Innovation is the answer

Automotive suppliers like Valeo are indeed increasingly responsible for the development of complete systems and technological solutions for their OEM customers. This added responsibility obviously requires greater coordination with one’s own internal and external suppliers and technological partners, from the product design and engineering stage through to production and delivery to the customer. It also entails an ongoing effort to find synergies and complementarities among different product families and activities within the company, which can lead to the creation of innovative solutions that are reliable, economical and meet both automakers’ and consumers’ needs.

Valeo has long been a global leader in the supply of complete systems and solutions for safer, cleaner and more comfortable vehicles. The Group’s technological innovation and development activities are indeed organized into three market driven Domains – Driving Assistance, Powertrain Efficiency and Comfort Enhancement, in order to identify systems and modules which answer to essential market needs .

>> Driving Assistance

Our Driving Assistance Domain develops systems that enhance driving safety by monitoring the vehicle’s immediate environment and informing or alerting drivers and other road users of potential hazards, or providing this information to other vehicle systems. We have developed a full range of radar, ultrasonic and camera-based systems – showcased on our V360 demonstration vehicle – which provide drivers and vehicle systems with 360° vision by day or night. Blind spot detection, lane departure warning, dynamic bending light and night vision are just a few of the featured functions. Equally important for safety are the obstacle detection and parking assistance functions we have developed, including the new Park4U™ semi-automatic parallel park assist system featured as a world premiere on the 2007 VW Touran.

>> Powertrain Efficiency

Powertrain Efficiency is another key Domain, responsible for developing cost-effective systems that improve performance while reducing fuel consumption and emissions. Valeo is a world leader in this field, with a variety of thermal management, exhaust gas recirculation and micro-hybrid starter-alternator solutions already on the market, including the “Start-Stop” StARS system introduced in 2004 on the Citroën C3. This system reduces fuel consumption by up to 28% in congested urban driving conditions. Another promi-sing solution now in development is the camless engine system, upromi-sing smart variable valve actuation, which should further reduce consumption and emissions by 20% in the future, whilst improving low end torque.

>> Comfort Enhancement

Our third Domain of technological innovation, Comfort Enhancement, is dedicated to enhancing the health and well-being of drivers and passengers, notably through the development of systems that filter and purify cabin air. Vehicle access and security, as well as ergonomics and the Human Machine Interface (HMI) are other key areas covered by this Domain, with solutions including smart hands-free keyless entry and remote-controlled power closure systems, supervised by safety oriented sensor systems.

All of these solutions are not just dreamed up by our engineers, however. Our innovation process is driven by real consumer needs. Valeo uses a wide variety of regional consumer surveys and focus groups to test end-user interest and acceptance of new automotive features and systems.

>> Operational excellence

The 5 Axes methodology is deployed in all the Group’s sites worldwide.

The 5 Axes methodology is the Group’s standard for obtaining operational excellence and Total quality at the best possible cost. Methods, manufacturing, projects and purchasing are systematically optimized.

The 5 Axes - Involvement of Personnel, Production System, Constant Innovation, Supplier Integration, and Total Quality - have formed the cornerstone of Valeo’s culture for the last 5 years, with the ultimate objective of achieving customer satisfaction.

Valeo uses a full range of tools to enhance operational excellence, such as “pull-flow” or Kosu, which assesses the resources required to manufacture a particular part. Valeo’s pur-chasing department is permanently optimizing its costs through a strategy of selecting and integrating suppliers, and putting all its tools at their disposal.

>> Total Quality

Quality is a founding principle. It relies on method but first and foremost on a state of mind.

Total quality is an obsession for Valeo’s 70,000 employees. It requires the involvement of everyone at all times and in all circumstances.

San Gen Shugi is a common-sense, logical approach to problem solving based on a concrete analysis of what really happens on the production line: Gen-ba (where and when a problem arises), Gen-butsu (analyzing actual parts), Gen-jitsu (using measurable facts).

QRQC (Quick Response Quality Control) is used to detect and analyze any problem and deploy immediate corrective actions.

This approach applies to all domains: production, quality, purchasing, logistics, safety and projects.

StARS starter alternator

The StARS starter alternator, available exclusively from Valeo, provides

automakers with the possibility of reducing fuel consumption in city driving by

up to 5%, without making any radical changes to their engine architecture.

>> A winning technology

The reduction of fuel consumption, greenhouse gases and pollutant emissions is one of the major challenges that the automotive in-dustry faces today. Automakers are making massive R&D investments in a bid to improve the efficiency of their engines. But progress is only made in small steps. Since, in city driving, vehicles are at a standstill for almost 35% of the time, during which the engine idles needlessly, the benefits of the Stop-Start system are quite obvious. This system switches off the engine when the vehicle stops, at a traffic light, for example, and starts it up again as soon as the driver asks for power. Valeo’s StARS solution (Starter Alternator Reversible System) fully automates this function and can achieve fuel consumption savings of up to 28% in congested city driving. The StARS solution combines the alternator and starter functions. In starter mode, the engine is started immediately and silently by the belt linking the system to the crankshaft. The alternator mode features a new technology that improves the electrical efficiency of the system. These two decisive advantages make StARS the ideal product to achieve fuel savings and to improve comfort by doing away with the vibrations and noise made by the engine when it stops and restarts.

Thanks to its advanced design, the StARS starter alternator can be adapted to any Stop-Start strategy required by the automaker. The system can also take into account a multitude of parameters related to the engine, clutch, gearbox, brakes or other comfort and safety equipment. It also allows the engine to be restarted when in the process of stopping, if, for example, the driver unexpectedly chan-ges their mind. Conventional starters do not offer this function. StARS can be used with any gasoline engine with a capacity of up to 2.0 liters and Diesel engines up to .6 liters, and with all types of gearboxes. By 2009, the system will be available for all gasoline- and diesel-fuelled vehicles, irrespective of the engine capacity.

In 2004, Valeo became the first automotive supplier to market a starter alternator. StARS was launched in Citroën C3 .4i 6V, and then in Citroën C2. Today’s smart fortwo mhd (micro hybrid drive) also offers the benefits of the StARS starter alternator. Valeo’s solu-tion reduces its fuel consumpsolu-tion in busy city driving by 3% to 4 l/00 km and emits just 03 grams/kilometer of CO₂ (provisional figures). The ingenious design of Valeo’s StARS starter alternator was rewarded with the 2006 PACE Award, the Grand Prix of the EPCOS/SIA Jury and the 2004 Engineering Award, distinctions that underscore the keen interest shown by the automotive industry in this solution.

>> Operating principle

The starter alternator is driven by a belt that can also be used to drive other accessories, such as the air conditioning compressor, the water pump or the power steering. A reversible tensioner allows power to be transmitted in both directions, depending on whether the StARS starter alternator is working as a starter or a generator. The system features a battery based on technology that accepts high numbers of charge/discharge cycles. The battery is also fitted with a sensor that enables the system to inhibit the Stop-Start function if the charge level is too low or to restart the engine if the charge level drops below a critical threshold.

>> Details of the StARS starter alternator

The StARS starter alternator is a synchronous machine with a claw rotor. It is air-cooled and uses a three-phase current that is trans-formed to 2 V DC voltage by a separate electronic transformer.

In starter mode, the electronic transformer delivers three currents with a 20° phase shift in relation to the data from the machine’s three position sensors. It is capable of delivering a 600 A current generating enough torque to drive the internal combustion engine immediately and at higher revs than a conventional starter. The machine can start the engine in less than 0.4 seconds, before imme-diately switching to alternator mode. In this configuration, the electronic transformer uses MOSFET field effect transistor technology to rectify the three phases. This is one of the reasons behind the outstanding 82% efficiency of the StARS starter alternator, which is a full 0 points higher than the best conventional alternators on the market. The machine delivers a current of up to 80 A.

>> The benefits of the StARS starter alternator

Advantages for the automaker

• The StARS starter alternator significantly reduces fuel consumption and CO₂ emissions with minimal investment. • At 2.5 kW at 4 V, the starter power is high.

• Electrical efficiency is greater than that of a conventional alternator.

• The engine can be restarted when in the process of stopping, if, for example, the driver unexpectedly changes their mind. • Installation on the cylinder block and electrical integration are simple.

• The length of the powertrain is not increased, as it is when starter alternators are incorporated in the shaft line. Advantages for the user

• Consumption is reduced by up to 5% in city driving. • CO₂ emissions are reduced by up to 5% in city driving. • The engine stops and restarts automatically.

• The engine restarts in less than 350 milliseconds and in complete silence.

• Engine noise and vibrations are eliminated when the vehicle is at a temporary standstill, which represents 35% of city driving time.

e-Valve System

The e-Valve system replaces the traditional camshaft system.

It reduces fuel consumption and CO

₂

emissions by 5%-20% while

improving low end torque up to 5%.

>> Attractive concept

In the current context of global warming, reduced CO₂ emissions demanded of the automotive industry by governments worldwides are challenging targets - especially within the relatively short timeframe requested. Valeo’s e-Valve technology allows automakers to reduce vehicle emissions and consumption by 5%-20% in a mixed driving cycle.

The opening and closing of valves is no longer controlled by a camshaft but by an electromagnetic system that operates each valve individually and independently of the crankshaft position. This total flexibility is similar to that available with very sophisticated varia-ble valve actuation systems, allowing engine calibration engineers almost infinitely variavaria-ble valve timing and valve opening duration. The e-Valve system also offers other advantages such as cylinder deactivation, offering additional fuel consumption benefits for the internal combustion engine.

It is now possible to design engines that optimize engine performance with respect to the demands of the driver, applying different engine strategies such as cylinder deactivation or Atkinson-Miller cycle based on actual driving inputs.

This flexibility in engine valve control also significantly increases low-end torque, enhancing driving comfort.

>> Operating principle

Each valve is controlled by two springs and two magnets. The two opposing springs provide alternating forces, one to open the valve, the other to close it. The two magnets catch the armature plate attached to the valve stem, the lower magnet to open the valve and the upper magnet to close it. The whole unit is controlled by an electronic management system (the Valve Control Unit) with an integrated 2/42 Volt converter and cooling system.

A benefit of the increased valve control flexibility is that the engine no longer requires an air throttle valve. This reduces or even eli-minates the negative pressure in the intake combustion phase at low engine speed (also known as pumping losses), which therefore improves fuel consumption. As a result, idle speed can also be lowered. The e-Valve system gives engine calibration engineers a wide choice of settings that can favor low-end torque, engine performance and reduced emissions. For example, deactivating certain cylinders - by temporarily closing their valves - enables the active cylinders to work in a more efficient portion of the engine map. All these new options contribute to the reduction of fuel consumption and CO₂ emissions by 5-20%.

>> The e-Valve system in detail

An e-Valve system has one actuator for each pair of valves. Valve movement is controlled by two magnets that harness the energy released by two springs. At the start of the valve opening operation, the valve is released by the upper magnet - the valve is then driven open (down) by the energy stored in the upper spring. The lower magnet catches the armature plate, fully compressing the lower spring and keeping the valve open for the required time. Valve closure follows the identical procedure in reverse. The valve is kept closed by a locking strategy, reducing the energy being consumed by the magnets. The valves also remain closed while the engine is not running. Noise due to the opening and closing of the valves is managed by controlling the speed of the valve as it reaches the upper and lower limits of travel.

The Valve Control Unit (VCU), which is cooled by the engine cooling system, operates on a standard 2-Volt vehicle architecture. It is fitted with a voltage converter in order to locally power the actuators with 42 Volts.

The flexible e-Valve system allows infinitely variable valve timing and valve opening duration, along with the possibility to deactivate some cylinders. In addition, by opening and shutting valves faster than a cam system at low engine speeds, pumping-related losses are reduced and almost eliminated. In addition to improved thermodynamic performance and torque, it is also possible to use several different combustion strategies such as switching momentarily to a Miller cycle, or accelerating gas intake speed by opening one valve and so reducing the creation of pollutant gases.

Current tests on prototype vehicles are focusing largely on half-camless systems, which control inlet valves only and offer most of the benefits and an excellent cost-benefit ratio.

>> Advantages of e-Valve System

Valeo’s e-Valve System represents a major technological advance in the design of internal combustion engines, and can offer many advantages to automakers.

• Pumping losses are reduced to virtually zero, which improves performance and lowers engine idling speed.

• Engine calibration engineers benefit from almost infinitely variable valve opening settings, with a positive effect on: - Torque, notably at low engine speeds

- NOx and HC emissions

- Ease of recycling exhaust gases • The system is highly adaptable on:

- A very wide range of engine displacements

- Indirect and direct injection, atmospheric and turbocharged, even highly turbocharged, gasoline engines - Existing engines - those already in production equipped with traditional camshafts

• The system is compatible with all fuel blends and quality

• The deactivation of cylinders increases performance at low engine speeds. Advantages for the user

Customers benefit from a more efficient engine, with lower fuel consumption and reduced CO₂ emissions. In addition, the customer benefits from enhanced driving comfort through increased low-end torque.

• Consumption is reduced by 5-20%. • CO₂ emissions are reduced by 5-20%. • Low-end torque is increased by 5-20%.

Exhaust Gas Recirculation (EGR)

Valeo is a European market leader in exhaust gas recirculation;

offering systems that further improve dynamic and thermal

performance.

>> A tried and tested solution

The success of diesel engines in Europe is largely due to their low fuel consumption and reduced CO₂ emissions. The growth in diesel engine’s market share has been made possible by reducing pollutant emissions with optimized combustion and post-treatment devi-ces. The carbon oxide (CO) and unburnt gas (HC) are reduced by a catalytic converter and the particles are processed in a self-regene-rating filter (DPF: Diesel Particle Filter). The nitrogen oxides (NOx) are reduced by the Exhaust Gas Recirculation (EGR) system. The EGR system takes part of the exhaust gases at the cylinder head outlet and re-injects them into the air intake. The main benefit is that NOx is reduced at the source by limiting the quantities formed in the combustion process, rather than by post-treating the gases. Consequently, the combustion process is cleaner.

The gases are only recirculated under specific conditions, when the engine is idling or only lightly loaded. An electric valve fully or partially opens the recirculating circuit, depending on the operating phase of the engine. The valve is driven by a powerful electric motor that guarantees reliable operation, even under the severe constraints imposed by temperature, exhaust pressure, condensates and a highly corrosive environment. The maximum throughput is high and the control of the valve position allows the recirculation rate to be precisely adjusted. The system works in association with an electric throttle valve on the intake side that reduces the quantity of intake air. It is completed by a heat exchanger between the recirculated gases and the engine’s cooling circuit, which lowers the temperature, thereby increasing the reduction of NOx.

Valeo is one of Europe’s leading EGR system suppliers. With the expert knowledge of the Engine Management Systems and Engine Cooling branches, Valeo has the skills required for research and development of the exhaust gas recirculation function. EGR systems for gasoline engines are also available to reduce CO₂ emissions.

>> Operating principle

The new electric EGR valve is made up of an electric motor, gearing, a cam system, a valve and a position sensor. With a high-power DC motor, the valve can be fully opened or closed in just 00 and 75 milliseconds respectively. One of the system’s most distinctive features is the progressive cam-driven control device that converts the rotary movement of the engine into controlled downward travel of the valve. The valve’s opening mechanism must be very reliable; in a highly corrosive environment, it must take into account the risk of the valve being jammed by soot deposits or oil combustion residues. The rotation/travel ratio of the cam increases the thrust force by significantly gearing down the movement. Once the valve is open, the second priority is the speed of travel of the valve. The gradient of the cam is then gradually increased. The cam also ensures that the valve can be closed tightly and quickly. The cams are linked to the valve by two bearings that eliminate friction and risk of seizure.

Valeo has opted for an outward-opening valve for greater dependability, since the high exhaust gas pressure generated by a turbo-charger applies a force that tends to close the valve. Pressure loss in the gas recycling circuit is low thanks to the clearance area, the aerodynamics of the valve head and the small diameter of the shaft. This property is especially important when idling and with very low loads. A Hall-effect sensor precisely measures the position of the valve. This is an important point, since a precise recirculation rate reduces the flow tolerances and enables the engine to comfortably meet the requirements of the Euro IV standard and, more importantly, the Euro V standard.

(11)

The capacity to cool the exhaust gases is another major factor contributing to the reduction of NOx, and Valeo has succeeded in im-proving the heat exchange capacity with engine coolant. The round corrugated tubes developed for Euro IV have been replaced by flat corrugated tubes to meet Euro V emission standards. This increases the heat exchange surface, resulting in thermal efficiency of 85%, and a reduced exhaust gas pressure drop. A U-shaped heat exchange circuit reduces the dimensions of the part. The gases can bypass the cooler via a pneumatically controlled flap. This function is essential for Euro V-compliance and is useful after engine cold start, when the temperature in the combustion chamber must increase quickly in order to minimize toxic emissions.

>> NOx reduction in detail

High quantities of nitrogen oxides are produced in combustion at high temperatures with excess air. Consequently, both of these parameters must be reduced. By recircuating part of the exhaust gases into the air intake, the mass of intake air is reduced, as are the quantities of oxygen and nitrogen available for combustion. The mass of intake air is also limited by partly closing the intake circuit. Lower quantities of oxygen also help to lower the combustion temperature. The heat exchanger, which is cooled by the engine’s coolant, lowers the temperature of the recycled exhaust gases, which in turn reduces the combustion temperature. The temperature can be further reduced by incorporating the UltimateCooling™ concept, which is capable of further lowering the temperature of the coolant whenever necessary.

Exhaust gases are only recycled under certain conditions, when the engine is idling or only partly loaded, because in these circums-tances, combustion occurs with excess air.

>> The benefits of the EGR system

• The EGR system avoids the need for NOx post-treatment devices.

• The power of the cam-controlled electric motor offers dependability and enables the valve to be opened and closed quickly. • The valve remains closed in the event of a malfunction.

• The U-shaped circuit reduces the dimensions of the exchanger.

• The exchanger and bypass valve are protected against high temperatures and exhaust gas surges when the EGR valve is closed (when the valve is on the exhaust side).

• The thermal efficiency of the heat exchanger is 85% with minimal exhaust gas back-pressure. • Valeo is the only supplier of the full EGR systems that includes the valve and heat exchanger. Advantages for the user

• With an EGR system, vehicles can meet the requirements of Euro IV and upcoming Euro V standards without a significant cost im-pact, unlike other post-treatment solutions.

Double dry clutch

Valeo offers a double dry clutch that provides comfort when

shifting gears and fuel economy when compared to other automatic

transmissions.

>> The technology

The double clutch gearbox offers the automotive industry a future automatic transmission solution that provides a combination of comfort of use and reduced vehicle fuel consumption. Valeo offers a double dry clutch developed using its manual gearbox expe-rience. When coupled with electro-mechanical actuator technology, this concept offers significantly higher performance than that of the hydraulically actuated double clutch systems currently fitted in double clutch production vehicles.

The double dry clutch is designed to offer maximum comfort when shifting gears. This comfort is provided by ensuring controlled slipping of the plates in both clutches during gear changes. Valeo handles this harsh clutch use by offering an integrated clutch and actuator solution. This solution couples technologies already tried and tested in series production, such as bonded rather than riveted linings, with specially-developed technologies ensuring double-clutch strength and reliability, such as travel adjustment integrated within the actuators.

The double dry clutch offered by Valeo contains three plates. The central clutch plate is fixed axially and its rotation is linked to the engine’s flywheel. A disk presses on each side of the central plate, and a moving plate presses in turn on the disks. The disk on the plate’s motor side engages both when starting and when shifting to odd gears. The plate on the plate’s gearbox side engages only when shifting to even gears and reverse. The plates transmit torque to two coaxial shafts: one of them is hollow and is used for even gears, and the other passes inside it and is used for odd gears.

The plates are engaged by an electromechanical actuator applying a force, via a release fork, to a diaphragm spring that presses onto the corresponding moving plate. Both clutches are disengaged when at rest.

>> The double dry clutch in detail

To obtain maximum comfort during gearshifts, sufficient controlled slip from both plates is required. When one plate is disengaging, the other is engaging, meaning that the mechanism must withstand a high thermal load applied for a very short time. This heat is absorbed through a careful choice of materials. The slipping movement also increases plate wear. Valeo therefore utilizes its Tripod® plates with bonded linings (already in use in single clutches) offering a longer clutch plate life. This exclusive patented technology allows the total thickness of both plates to be reduced and thereby optimizes the thermal mass, which is key in efficient double dry clutch operation.

The engaging of a clutch requires the balancing of the forces applied by the diaphragm and those by the actuator. In order to reduce the demands made on the electric motor, the actuator includes an assisting spring. This utilizes a cam to apply a force almost equal to that applied by the diaphragm. The electric motor then provides the additional force required to control the plate engaging and disengaging actions, thereby consuming less energy. 5 Amperes electric current are required during gearshifts, and only Ampere is required between gearshifts to keep both clutches closed. This contributes to Valeo’s double dry clutch exceptional efficiency. Lastly, the actuators include a bi-directional travel adjustment mechanism that adjusts for disk wear and also adjusts automatically to com-pensate for production tolerances. This last point simplifies the vehicle assembly process.

(13)

8

If requested, Valeo can alternatively supply an automotive manufacturer with its electro-mechanical actuators alone, for fitting to wet friction clutches.

The double dry clutch can be fitted in conjunction with a dual mass flywheel if required for particular diesel or gasoline engines. The permitted torque range for a transverse gearbox varies from 200 to 350 Nm depending on the clutch plate diameter defined by the space available, the vehicle weight and the gearing reduction in the gearbox’s first gear.

>> Valeo double dry clutch advantages

Valeo offers a highly efficient mechanism, providing exceptional performance:

• The double dry clutch is more efficient than an automatic gearbox or a double wet clutch, due to the following: - The clutch plates are dry instead of being immersed in an oil bath, requiring a hydraulic pump

- Use of electro-mechanical rather than hydraulic actuators

The system results in an approximately 0% reduction in CO₂ emissions compared with an automatic gearbox and an approximately 4% reduction compared with a wet friction double clutch gearbox.

• Reliability is ensured by the careful choice of technologies that minimize the number of double clutch components, the use of clutch plates with bonded linings and the wear adjustment mechanism integrated in each actuator.

• The double dry clutch can be easily adapted to a large number of gearboxes. Advantages for the user

The customer enjoys not only better performance and improved fuel economy but also improved comfort and driving pleasure: • The Valeo double dry clutch system provides the comfort of an automatic transmission coupled with lower fuel consumption than

that offered by a manual transmission.

• This system also provides a truly pleasurable driving experience, compared to an automatic gearbox, by allowing the user the option of shifting gears without any torque interruption.

(14)

UltimateCooling™ System

The UltimateCooling™ system offers a major advance in comprehensive

vehicle module temperature management.

>> A totally new thermal management concept

A combination of up to four heat exchangers in a vehicle’s front structure is currently commonplace, with an engine cooling radiator, air to oil cooler, a charge air heat exchanger and an air conditioning heat exchanger. Valeo’s new UltimateCooling™ concept utilizes a single coolant for all heat exchangers, limiting the number of front-end exchangers and improving thermal flows.

The system is made up of two thermal loops, one cold and one hot, each feeding different heat exchangers located as close as possible to the unit requiring cooling or heating. This global approach also reduces the total volume of the cooling system.

UltimateCooling™ feeds all units requiring a cold loop in addition to those requiring a conventional hot loop, regardless of their loca-tion. An electric water pump, coupled with a valve (if required), provides the coolant flow according to the required uses and priorities. The cold loop feeds the charge air heat exchanger located at the cylinder head intake, the fuel cooler and the air conditioning water condenser. The hot loop is responsible for cooling the engine and the engine or transmission oil, and heating the cabin. The exhaust gas recirculation (EGR) system cooler and other additional systems may be connected to one or the other of the loops.

The circuits are therefore more efficient and less bulky, requiring less space in the front-end of the vehicle. This will help meet future pedestrian impact standards, and reduce the number of leaks and repair costs in the event of front-end impacts. The hot and cold loops are cooled either by a single dual-circuit radiator or by two separate radiators.

>> UltimateCooling™ in detail

The sizing of conventional cooling circuits is based on extreme use scenarios. The air conditioning system’s condenser is sized for operation when idling and/or at low speeds, whereas the engine’s radiator and the charge air heat exchanger are sized for driving at maximum speed or towing a trailer in mountainous conditions. A single coolant is used to ‘share’ the capacities of all front-end heat exchangers, and thereby improve their efficiency. UltimateCooling™ therefore reduces the volume of the thermal management system while providing equal or better performance.

UltimateCooling™ will give priority to cooling the air conditioning system’s condenser during startup conditions, or the engine in hot weather (to cool down the vehicle) and as such both cold loop and hot loop radiators will be used. When considerable torque is re-quired, the charge air heat exchanger, or the EGR cooler in other cases, will utilize the cold loop radiator (which is also sized to supply the condenser, as the air conditioning system requires less power when the vehicle’s speed increases and the thermal comfort level is reached inside the vehicle).

The cold loop’s distribution within the vehicle allows optimal positioning of the various modules, and avoids transferring liquids under high pressure to the front of the vehicle.

(15)

0

It is also possible to adjust the UltimateCooling™ system’s efficiency by means of a control valve between the hot and cold loops. In certain cases, only part of the high-temperature radiator will be required to cool the engine (during urban and highway driving or when ambient temperature is below 35°C, conditions frequently experienced when driving a vehicle), enabling the rest of the radiator’s po-tential to enhance the cooling of other functions.

Lastly, a reduction in the number of heat exchangers in the front-end of the vehicle reduces the vehicle’s required vertical dimensions, which could facilitate meeting «pedestrian impact» standards, as well as reducing the required depth. In a mid-range vehicle prototype produced by Valeo, the maximum depth was reduced from 8 mm to merely 50 mm with a multi-temperature radiator or 60 mm with two radiators, and the total volume of the cooling system was reduced by 22%.

>> UltimateCooling™ Advantages

The UltimateCooling™ system offers significant vehicle development potential:

• The intake air cooling system is more efficient. Its circuit is shorter, reducing lag time under acceleration, and the pressure loss between the charge air compressor and the intake manifold is also reduced.

• Engine performance is increased and pollutant emissions are reduced.

• The improved efficiency of the charger air’s cooler and the air conditioning condenser increases the vehicle’s overall energy efficiency. Fuel consumption can be reduced by up to 6% in a MVEG mixed cycle with the air conditioning operating.

• The multi-temperature radiator reduces the front-end module’s dimensional requirements by 40% and maximum depth requirements by approximately 50%.

• The vehicle’s Cx can also be improved due to use of a smaller front-end opening.

Water Cooled Charge Air Cooler

The air-to-water heat exchanger provides enhanced charge air cooling.

>> More efficient air-charging

The intake air entering turbo- or supercharged gasoline or diesel engines is traditionally cooled by an air-to-air heat exchanger located in the front-end of the vehicle. The system offered by Valeo is instead an air-to-water heat exchanger, in which the intake air is cooled by coolant flow. The turbo- or supercharger system therefore benefits from more efficient cooling coupled with a shorter airflow path, which improves engine response times under acceleration.

The Valeo water cooled charge air cooler’s first mass-production application was introduced in the Volkswagen Golf TSI engine exhibited at the 2007 IAA Frankfurt Motor Show. The unit represents the first step towards Valeo’s new global cooling concept, UltimateCooling™.

The water cooled charge air cooler is produced in brazed aluminum and provides considerably reduced pressure losses compared with air-to-air cooling. This heat exchanger can be located in the engine’s intake manifold, eliminating the need for hoses between the engine and the front-end of the vehicle. The reduced volume between the compressor outlet and inlet valves improves acceleration response time, reducing the time taken to attain maximum boost pressure at the engine’s intake by approximately 50 milliseconds at 500 rpm (a 4% improvement).

The charge air cooler’s coolant circuit is totally independent of the engine’s cooling circuit. As its temperature is a maximum of 5-20°C higher than ambient temperature, the charge air cooler’s coolant circuit is called a cold loop and can lower the temperature of the intake air easily since the heat absorption capacity of the coolant is higher than that of air. The intake air temperature rises by less than 5°C under acceleration at full load, compared with 20-30°C for an air-to-air system, due to its greater efficiency and inertia. The coolant is then cooled by a small radiator, which is located at the front or side of the vehicle and fed by small diameter (approximately 20mm) coolant hoses. The flow is driven by a low-powered electric pump.

>> Water Cooled Charge Air Cooler Advantages

The Valeo air-to-water heat exchanger offers many advantages over a conventional air-to-air cooler:

• It improves vehicle response times under acceleration. It ensures enhanced control of combustion parameters (the air temperature is virtually constant at the engine’s intake manifold) and provides denser intake air due to its improved efficiency and low internal pressure losses.

• Less pressure is lost between the turbo- or supercharger and the cylinder head intake, and the compressor’s workload and consumption are reduced while achieving the same engine intake air pressure. Alternatively, a higher intake charge air pressure can be provided, providing enhanced engine performance from the same compressor load.

• The unit is more compact: the cooling module in the front-end of the vehicle is up to 20% smaller, and the long charge air ducts leading to a heat exchanger at the front of the vehicle have been eliminated. Installation of a turbo- or supercharged engine in the engine compartment is simplified.

(17)

• This concept simplifies implementation of the future pedestrian impact standards. • Repairs resulting from a front impact are reduced (no air-to-air cooler out front).

• The water cooled charge air cooler will enable the introduction of future low-pressure EGR systems that can contribute to the reduction of nitrogen oxide production more efficiently in diesel engines.

Advantages for the user

The benefits of the air-to-water charge air heat exchanger are noticeable to customers: • An improved engine response time under acceleration.

• When coupled with the longer gear ratios accepted by turbo- or supercharged engines, the charge air cooler’s improved efficiency reduces fuel consumption by up to 2%.

THEMIS™ electronic valve

The THEMIS™ valve provides complete, intelligent control of

cooling system flows.

>> The first intelligent temperature control system

THEMIS™ (THErmal Management Intelligent System) is an electronic valve (with associated control strategies) that constantly optimi-zes, under all conditions, the flow and temperature of the engine coolant. With a wide range of settings, the proper management of the coolant flow improves the operation of many other functions.

This adaptability increases engine efficiency, saves fuel and reduces pollutant emissions, as well as enhancing comfort in the cabin.

The THEMIS™ valve, which is located at the outlet of the engine’s cooling circuit, replaces the conventional thermostat. It consists of a four-way rotary slide valve that progressively opens the engine cooling radiator, bypass and cabin heating circuits. The rotary valve, whose position is detected by a position sensor, is actuated by a brushless electric motor.

The opening and closing of each circuit is managed by predictive software developed by Valeo, which integrates the current tempe-rature, engine data and driving style parameters and incorporates a closed loop control algorithm to handle minor fluctuations. The system readjusts the flows before each measurement.

THEMIS™ can also enable the faster heating of the cabin, and maintain cabin thermal comfort even after the engine has been swit-ched off. The system provides optimized thermal distribution where and when it is needed.

>> The THEMIS™ valve in detail

A conventional wax thermostat’s operation is controlled by the temperature of the coolant flowing through it and does not react to the powertrain’s immediate needs, sometimes resulting in an operating lag.

Under strong acceleration, the engine immediately provides full power but the additional thermal energy also generated is detected only when the hot coolant has already passed through the cylinder head and reaches the thermostat. Engine designers must there-fore take into account the lag between the immediate production of heat and the cooling system’s activation. The resulting safety margin means that the coolant in the engine block and cylinder head does not remain at the optimum temperature but instead varies between 90 and 0°C.

These variations can be anticipated by using a rapid-response valve and an intelligent control unit algorithm. The valve’s electronic control ensures that the coolant maintains its optimum temperature, 0°C for example, while limiting deviations to +/- 2°C (compa-red with +/- 7°c for a conventional thermostat). The valve also opens in less than second, (compa(compa-red to 20 seconds for a conventio-nal thermostat), thus, improving engine performance. Combustion knocking effect can be reduced and combustion efficiency can be improved. The oil temperature can also be controlled more accurately, resulting in reduced viscosity and lower friction-related energy losses. The result: improved fuel consumption, CO₂ emissions, pollutant gas emissions and performance.

Other engine functions are also improved. “Zero flow” mode is provided when the THEMIS™ valve completely closes all of the circuits. This mode is used when starting up a “cold” engine, enabling the temperature of the combustion chamber walls to rise rapidly and

(19)

improving heat transfer to the engine oil. Test results on a gasoline engine have shown a 30°C rise in temperature of the cylinder head metal touching the combustion chamber in the first few seconds after the engine is first started. Unburned hydrocarbon and carbon monoxide emissions, along with engine oil dilution with fuel resulting in a shorter engine life, are therefore reduced. The THEMIS™ valve also considerably improves cabin comfort. Hot coolant normally passes continuously through the heater core in the air conditioning system, and parasitic thermal waste reduces the air conditioning’s performance in summer. In this case, the THEMIS™ valve closes the hot coolant circuit to the heater entirely. A reduction of up to 5°C in the vent discharge air temperature has been measured in our tests, improving passenger comfort. Additionnaly, when cabin thermal comfort conditions are met, reduced work is demanded of the air conditioning compressor and consequently the vehicle’s fuel consumption can be improved.

The THEMIS™ valve used in conjunction with a low-powered auxiliary water pump in the cabin comfort circuit can assist in maintai-ning a comfortable temperature when the engine is runmaintai-ning slowly or during temporary stops. This pump also prevents the engine from overheating if it is switched off immediately after running for a long period at maximum output. In this case, the engine is cooled by a coolant flow that passes through the radiator and coupled with the action of the engine cooling fan, this can prevent a dangerous rise in engine temperature (afterboil).

>> THEMIS™ Valve Advantages

The THEMIS™ valve provides the possibility to accurately control the cooling system under all circumstances taking into account many parameters, including coolant temperature:

• Engine efficiency is improved by maintaining the coolant temperature much more accurately at 0°C. A related 3% reduction in fuel consumption has been measured in testing.

• The water temperature is adjusted according to the engine’s load.

• “Zero flow” mode accelerates the engine’s temperature rise when cold, reducing the production of pollutants, etc. Hydrocarbon emission reductions of 0% and carbon monoxide emission reductions of 20% have been measured under mixed cycle conditions (MVEG cycle).

• The THEMIS™ valve improves engine and cooling system reliability:

- The engine does not overheat if switched off after a long period at full load (at the top of a hill, for example). - The risk of combustion knocking effect is reduced due to the fast response time of the THEMIS™ valve. - Engine thermal shocks are eliminated.

- Radiator thermal shocks are eliminated.

- A safety device opens the circuits in the unlikely event of an electrical failure.

• By closing the cabin heating circuit, the air conditioning compressor’s and water pump’s workload is reduced. The air conditioning compressor and the water pump can both be downsized.

• The THEMIS™ valve improves heating and maintains cabin comfort during colder months in hybrid vehicles and stop-start vehicles. • The THEMIS™ valve is easy to install at engine’s water outlet.

The customer enjoys better fuel economy but also increased comfort both in winter and summer. • Fuel consumption is reduced due to improved engine temperature management.

• CO₂ emissions are reduced as a result. • Engine and radiator reliability is improved.

• The cabin is heated more rapidly after the engine is started up in winter during urban driving conditions. • Air conditioning is more efficient.

STOPStayCOOL

STOPStayCOOL is an evaporator that continues to provide cool air when

the engine is temporarily stopped, a situation that is likely to become

more frequent with the uptake of the Stop-Start function.

>> Comfort and savings

The Stop-Start function is expected to be introduced in high volumes in the near future. This system significantly reduces fuel consumption and pollutant emissions by automatically and temporarily stopping the engine when the vehicle is at a standstill. When the engine stops, conventional air conditioning systems cannot continue to operate. Valeo’s «STOPStayCOOL» system stores cold energy, which is then released when the vehicle’s engine is temporarily stopped, saving energy without compromising the comfort of the vehicle’s occupants.

STOPStayCOOL is an air conditioning evaporator that performs the normal function of cooling the air in the cabin, while storing cold energy at the same time. The cold energy is stored by a phase change material in contact with the evaporator. The cold energy is stored using the energy required for the material to change phase: the material becomes solid when it is cooled, this cold is then released when the material returns to the liquid phase. The air conditioning can then generate cold air even when the compressor is not driven.

The system operates for about 45 seconds (operating time depends on ambient temperature), a duration that represents 90% of temporary stops in Europe. The duration is limited by a threshold applied to the temperature of the air in the evaporator (2°C). The STOPStayCOOL evaporator is recharged with cold energy when the compressor (and engine) restarts. Just 30 seconds are required to reach maximum capacity under normal operating conditions.

This additional feature requires the width and weight of conventional evaporators to be increased by 0% and 500 grams respectively.

>> The benefits of STOPStayCOOL

• The STOPStayCOOL evaporator continues to supply cold air when the engine is switched off.

• When associated with a Stop-Start system, this evaporator maintains the required temperature inside the vehicle while the engine is shut off.

• The system is easy to integrate into the air conditioning system. Advantages for the user

• The fuel savings made with the Stop-Start function are now compatible with air conditioning by avoiding the need to restart the engine to maintain a comfortable temperature inside the vehicle.

VALpower: the solution for rear

battery connection

An alternative to copper - aluminum bus bar is less expensive and lighter.

>> Perfect solution for vehicles equipped with rear battery

Due to the continuous integration of new electronic functions in on-board vehicles, electrical power needs are increasing. Space in the engine compartment, therefore, is becoming crucial. Thus, many cars have their batteries relocated into the trunk of the car. VALpower is a product optimized especially for rear battery applications.

In order to adapt innovation to a technological environment, Valeo developed a new product: VALpower. It is an aluminum bus bar connection for vehicles equipped with a rear battery.

>> The technology

The connection between the battery and the engine is currently made with copper, even for rear batteries, which implies heavy and expensive harnesses. Valeo proposes a new solution, the bus bar in aluminum. This innovation consists of a 3D bending aluminum rigid bar, and can be adapted to any routing under the car body. It is welded with an ultra-sonic technology at each extremity of the bar, if necessary, to a standard flexible wire in order to ensure the flexibility needs in the front engine or in the rear trunk.

>> Advantages of the VALpower

The use of aluminum allows for significant weight and cost reductions. First, for the same conductivity, weight reduction can be redu-ced to 3kg. The second advantage is price, aluminum is 0% cheaper than copper flexible wire. The third advantage is dimension for large sections; the external diameter of an aluminium bar can be smaller than that of flexible copper wire and even smaller than an aluminum flexible wire. The last advantage is rigidness which allows an automatic assembly on the manufacturer’s production line.

“Smart Closure”: automatic Power Closure System

with movement detection

Valeo, a leading expert in powered closure systems, announces its

tailgate and trunk closure system combined with a presence detector.

>> Safety and ease of use

Valeo’s smart tailgate closure system makes this automatic function even easier to use. The powered tailgate closure is activated operated by a button located in the trunk. This smart system checks that no adults or children are in the tailgate’s way before auto-matically closing. Users can command the tailgate to close before taking away their luggage with both hands. The tailgate will not close until everyone has left the defined rear detection area.

The system uses the existing four or six ultrasonic sensors at the rear that are part of the Park Assist function.

>> Functioning description

The Smart Power Closure System (Smart PCS) uses ultrasonic sensors used for objects or persons detection within a distance of 0 to 20 cm and capable of detecting people walking away from the vehicle by checking their movements every 00 milliseconds. The tailgate only starts to close automatically if there are no obstacles and when everyone is at a safe distance. If anyone starts moving towards the vehicle, the system automatically stops the tailgate.

Once the tailgate is closed, the sensors resume their park assist functions.

Valeo supplies all the system’s component parts, which include the powered actuators, four to six ultrasonic park assist sensors and the closure system software wich controls the position and speed of the actuators, performs the anti-pinch function and contains the sensor detection programs.

>> The benefits of the Smart PCS

• The car manufacturer can offer a new comfort option to its customers.

• The Smart PCS does not require any additional parts for vehicles that are already fitted with powered tailgates and park assist sensors. Advantages for the user

• Users can command the tailgate to close and then pick up their luggage with both hands.

• Safety is improved by presence and movement detection, which is added to the anti-pinch function. The safety is increased by movement detection by completing the obstacles detection functions.

Electric Compact Spindle Drive for trunks

and tailgates

Valeo extends its range of powered closure systems for trunks and

tailgates with a new technical solution: the Compact Spindle Drive.

Valeo, a leading supplier of powered closure systems, announces its new 35 mm diameter electric actuator, with a maximum pull force of around 000 N and travel of up to 250 mm.

>> Easy to integrate technology

Fitting motors that are linked to the hinges of a closure system can reduce rear visibility and often require certain parts of the vehicle, such as the hinges, the opening panel and the roof, to be reinforced.

With the Compact Spindle Drive (CSD) which avoids high mechanical loads on the hinges, Valeo meets the car manufacturer’s requests. The CSD is mounted in place of the conventional gas springs, preventing any interference with the driver’s field of vision.

>> Functioning description

The Compact Spindle Drive is composed by an electrical motor a gear box and a spindle which converts the rotary movement into linear motion. The power requirement is reduced by an internal compensation spring. The combination of this specific adjustes spring and the reversible spindle enables the tailgate to be opened and closed manually and supports the tailgate in any position, even on gradients, without electric power.

>> Details of the Compact Spindle Drive

The system is designed for tandem installation on each side of the vehicle. The movement of the actuators is commanded by an ECU which controls speed, position and direction of movement. A Software controls the speed of the actuators for smooth tailgate mo-vement. This prevents torsional stress in the structure of the tailgate. The ECU analyses the data from the position sensors integrates into the actuator.

The system includes a pinch force limitation which detects obstacles reliably. A contact detection sensor strip can also be added on the tailgate or the car body.

(24)

>> The benefits of the Compact Spindle Drive

• The Compact Spindle Drive can easily replace gas spring, which can be provided as alternative design for a single model. • Installation on the vehicle assembly line is similar to that of traditional gas springs.

• With its reasonably sized diameter, the CSD can be easily integrated.

• Noise and mechanical stress caused by unsynchronized movements are limited by the control software. • Valeo has taken special care with the style and finish of the actuator.

• The comfort of a powered tailgate: simpler loading and no slamming (smooth and automatic closing). • No loss of volume in the luggage compartment.

Smart car key

The smart car key from Valeo brings new functionality

to access remote controls.

>> A connected device

Valeo’s prototype smart car key is capable of sending data from the vehicle to the driver and remotely activating vehicle controls. After Valeo’s well-known passive entry function, the smart key can exchange data with the vehicle. The key can transfer navigation addresses pre-loaded from a PC or pre-ventilate the vehicle’s interior. Confirmation of each command is returned to the key’s screen or buzzer. On the key’s screen, drivers can view information on the current status of the vehicle: are the doors locked or unlocked, is the alarm switched on, how much fuel is left and what about safety factors, such as the tire pressure? The key sends an alert if a command cannot be executed. A future version of the key will also be capable of locating parked vehicles.

With a modular design, the key can be adapted to offer varying levels of functionality.

>> How it works

The innovation consists in controlling the vehicle’s functions with a key that communicates over a long-distance radio link.

In Europe, Valeo has selected the frequency of 868 MHz in both directions for the prototype and the key is powerful enough to com-municate with the vehicle over distances of at least 200 meters. Different types of screen can be used. The prototype’s design allows the use of OLED technology color screens (organic LEDs) or black and white LCD screens. Both screen types are large (27x20 mm, i.e., 28x00 pixels) but can be resized according to car manufacturer requirements. The user interface is fitted with a beeper to inform users of alert messages when the key is in a bag or a pocket. Communications are not restricted to the vehicle, since the key is also capable of exchanging data with other keys so that they can be synchronized.

>> The advantages of the smart car key

For the car manufacturer

• A high-technology image projected by an offer that is rich in functionality.

• Design in harmony with the spirit of the manufacturer’s brand, a distinctive identifying factor. • Modular design and range of functions.

For the user • Increased comfort:

- Permanent access to up-to-date information - Communication with the vehicle over long distances • User-friendly design for easy and intuitive navigation.

The E-Media™ control system

E-Media™ system offers the ideal compromise between managing a

large number of functions and ease of use.

>> An intuitive control system

How to realize a simple, intuitive control system for comfort and communication functions, without limiting at the same time the range of electronic control options? Valeo answered this question with its amazingly simple E-Media™ interface. The system compri-ses three joysticks, each one controlling its own function group: audio, air-conditioning and communication (navigation, telephone, etc.).

The major advantage of the E-Media™ system is its ergonomic design, which reduces its menu depth to a maximum of two levels. One menu level could have been reduced due to the integration of touch-detection. As soon as the user places his hand on one of the joysticks, the screen displays the menu for the corresponding function group: audio, air-conditioning or communication. The graphic interface developed by Valeo’s design and ergonomics specialists facilitates users form a mental picture of how the system works: the vehicle’s central screen displaying schematically the position of each control and the manipulation movement. For example, the air-conditioning joystick is integrated in the rear right of the middle console, and the corresponding information is displayed in the bottom right-hand section of the screen. Circle, bar and arrow displays give the user an instant visual representation of controls being rotated or moved backwards and forwards, or from side to side.

To make the controls even easier, the driver can activate basic, frequently-used functions such as audio volume, temperature and phone contact list, by simply rotating the corresponding joystick. Furthermore, additional buttons give direct access to safety and shortcut functions, such as answering the phone or demisting the windscreen.

In addition to its highly ergonomic design, the E-Media™ system is characterized by its joystick technology. The joysticks offer three types of movement in seven different directions: rotation in both directions, tilting in four directions, and push function to confirm an operation. Rotation disposes of 8 to 32 dents per rotation, also available with magnetic indexing. This contact less technology has no deterioration over lifetime and offers the driver a more comfortable haptic perception. The joysticks also stand out by possible integration of touch-detection. This function allows the user to select one of the three function groups - audio, air-conditioning or communication – when touching the corresponding joystick and therefore skip one menu level. The technology uses capacitive sen-sors that measure the change in electrical resistance between the vehicle and the user’s body.

An additional advantage of the E-Media™ system is the easy integration with vehicle electronics. The system can easily communicate with all vehicle systems independent of the protocol: CAN, MOST, etc. Thus the system has been fitted in Valeo’s demonstration vehi-cle and now controls all original functions.

(27)

>> E-Media™ advantages

Advantages for the automotive manufacturer

• The E-Media™ system reduces the number of buttons without limiting the number of functions.

• The system allows the integration of a wide range of functions independent of the protocol (CAN, MOST, etc.).

• The joysticks can easily be customized concerning: number of movements, touch detection, magnetic indexing, illuminated fixed central symbol and finishing.

• The E-Media™ system is easy to use and offers a maximum number of comfort and safety functions. • Utilization is intuitive, thanks to a graphic interface that displays control movements and positions.

Senseative

®

Seat Controls

Senseative

®

replaces conventional buttons with touch-sensitive controls.

>> An even more intuitive control

A successful control system is a combination of good ergonomics analysis and optimal technical fine-tuning. This applies also to electric seat controls, which are represented as embossed seat cushion and backrest: moving the controls horizontally or vertically causes the corresponding parts of the seat to move. Senseative heralds a new step forward in the realm of ergonomics. Commands are executed by simply moving the finger on a more realistic representation of the seat.

With Senseative®_{, simply moving the finger across the control is enough to understand how this highly intuitive system works. The} four possible movements of the seat are represented by four segments. After pressing the ON button, the user slides the finger over one of the segments to move the corresponding part of the seat. The demonstration vehicle developed by Valeo is fitted with the Senseative®_system.

In each segment a resistive sensor, measuring about 250 µm in thickness, is implemented. Resistance varies according to the activa-tion force applied to the sensor. When the resistance drops, during this proporactiva-tional activaactiva-tion, below a pre-defined threshold a signal is send to the electronics. At the same time, the exact point where the user presses the sensor can be measured by fixed resistors integrated into the sensor.

This type of integrated sensor allows the controls to be used with bare hands and when wearing gloves. Accidental seat movements are prevented by the electronics, which require the finger to move in a pre-defined direction and to remain pressed until the required position is reached.

The controls are available with a broad range of surface finishes, and can be covered with plastics, silicon or metal. The surface can be backlit by LEDs or an electroluminescent foil, in order to display characters or pictograms directly on the controls. Actuators built into the component can also provide tactile feedback.

The application of this technology to seat controls is just one example of its potential. It can be used to improve the ease of use of a multitude of functions, such as interior lighting, sun roofs, and functions mounted on the steering wheel or the central console, like dialing a phone number or inputting the destination by means of handwriting recognition.

Thermeo

Thermeo is an easy-to-install add-on thermal comfort module

for rear passengers.

>> Simple, ingenious air conditioning

Because air conditioning vents are located at the front of the vehicle, little cool air reaches rear passengers. The most frequent so-lution has been to install a second air conditioning unit in the central tunnel, a bulky and expensive answer employed only in a few top-end vehicles. Now, however, Valeo offers Thermeo, a compact add-on air conditioning unit requiring only an electrical connection for installation.

The Thermeo module uses entirely thermo-electric technology to produce cold air, meaning that the installation of refrigerant pipes leading to an evaporator is no longer necessary. The cooling modules and their fans are extremely small, allowing installation of the unit in the vehicle’s roof, for example. The module then sends cool air towards the rear of the cabin. Thermeo is reversible, enabling the system also to provide warm air very quickly, even before the engine has reached its normal operating temperature. Another benefit of the system is that it can provide the left and right sides of the cabin with air at different temperatures, meaning that the temperature in each of the cabin’s thermal zones can be adjusted to the occupants’ personal preferences. A remote control unit can be used to adjust Thermeo from the front seats of the vehicle if necessary.

Thermeo is currently available to automakers only. It will later be offered as an aftermarket system. Installation is simple: it connects the vehicle’s cigarette lighter.

The secret of the Thermeo system’s operation lies in its cooling module. The unit is composed of plates enclosing a bismuth telluride semiconductor. It works by transferring heat between two surfaces. When an electric current is applied, one plate cools down while the other heats up (the Peltier effect). A silent pulser pushes air over the cold plate and into the cabin. The hot plate is cooled by a second module and the warm air is then expelled.

Thermeo utilizes a 2V power supply and only consumes 00W to lower the temperature by 5°C and 250W to raise it by 25°C.

>> Advantages

For the automaker

• a cost-effective solution for supplying passengers in rows 2 and 3 with immediate cold or hot air. • small and entirely electric, therefore easy to install.

• Low power consumption.

• Standardizes the conventional HVAC unit in a system for use in several bodies, permits the use of a standardized HVAC unit on all automotive platforms.

For the user

• Generates cold or hot air for passengers in the second and third rows of seats.

• Provides immediate comfort in winter, even before the engine has reached its normal operating temperature. • In-roof installation, freeing up space for storage.

Park4U™ Semi-Automatic Parking

The Park4U™ system takes care of the most complicated

maneuver in urban driving: parking.

>> Parking made easy at last

The Park4U™ system parks the vehicle parallel to the curb automatically in a few seconds. After it detects a sufficiently large parking slot, it controls the vehicle’s steering while the driver controls the vehicle’s speed and braking.

The simple process of finding a parking slot is begun by pressing the Park4U™ button. Lateral sensors scan both sides of the street
