to unpredictable and unintended external action with no apparent. In day-to-day life, all over the countries are pressurizing the vehicle rider to follow the certain rule such as to wear the helmet and also the riding should be prohibited when the person is in drunken condition and also when the rider is on phone. But still the rules are being violated by the users. In order to overcome this we introduce an embedded based intelligent system.Smart Helmet system, which automatically detects whether the person is wearing the helmet and at the same time as non- alcoholic breath while riding. But the main aim of our proposal is to develop prototype of black box for wheeled vehicle analysis that can be retrofit into any vehicle. This prototype can be designed with minimum number of circuits. This can contribute to construct safer vehicles, improving the treatment for crash victims, helping insurance companies with their vehicle crash investigations, police investigations and enhancing road status in order to decrease the death rate. Its potentially life -saving features include accelerometers, real time clock, ultrasonic distance meter. Together the features provide the rider with information while riding or data in the event of an accident.

ABSTRACT: Solar Photovoltaic (PV) systems are having increasing importance in present time of electrical power system due to its non-polluting nature, less maintenance, and free fuel characteristics. Solar photovoltaic technology is considered as oneof the pure and clean technologies to produce electricity, but seems unattractive towards the use of it as a complement of electricity due to its low efficiency and high initial cost. As a result of its low efficiency it is nearly impossible to exploit the maximum solar power coming out of array therefore at its highest energy conversion output it leads to the operational failure of the device. As the radiation and temperature has their effects on the maximum power point, it is likely impossible to provide power operation at optimum level during all radiation levels.The efficiency of commercially available solar PV module is very low in the range of 10-25 %. In order to maximize their operating efficiency and to reduce installation cost, maximum power point trackers (MPPT) are coupled with the system. In this paper we are presenting the design and implementation of solar PV and MPPT controller for electric vehicles
Abstract—This paper describes the systemdesign and implementation of a vehicle management system and covers the following five sections: (1) GPS signal. (2) Microcontroller functions. (3) SD card storage technology with FAT32 file system. Most MCU use FAT16 file system to manage files, but it wastes a lot of memory space when small files are stored to each cluster. Using the FAT32 file system will ensure an efficient use of the memory space. (4) GPRS transmission. (5) Real-time monitoring Server, which is used to monitor vehicles accurately in real-time. The system adopts a web-based solution aimed at gathering the information of vehicle’s status and location in real-time. The location information is exposed with geographic coordinates, computed by a GPS processor in vehicle. The processor is embedded in the proposed device, a driving recorder, installed on a vehicle and responsible for transmitting location information to monitoring server. The recorder is a portable, highly accurate, and low powered vehicle tracking device, implemented with TI MSP430F5438 microcontroller.
Abstract: Accurate ship navigation is very essential for saving fuel as well as time. In order to achieve accurate tracking in Autonomous Ship navigation various controllers like PD, PID, Predictive and Adaptive controllers are used. In this work we design an autonomous system using PID controller to increase tracking efficiency. PID was chosen because it allows real-time implementation of an Autonomous Surface Vehicle. The work started with the implementation of supporting hardware like Brushless DC Motors, ESC for BLDC motors speed control. We then later interfaced GPS and Compass and Telemetry to check for the working of our system by giving waypoints and observe the course tracking. With the Implementation of PID along with all the above we get bet better tracking efficiency and computation is faster.
The system integrates with three type sensors to detect and decide the distance of obstacles. When the obstacle is located at a distance 20 ~ 40m, as shown in Figure 8 (a), LiDAR is unable to recognize the position of obstacles due to insufficient information. In the meanwhile, the system applies characteristics of millimeter wave radar that provides long-distance information steadily to recognize the distance of obstacle. In the short distance, the identification ability of LiDAR increases comparatively, as Figure 8 (b) shows that distance is 2 to 20 meters. Therefore, LiDAR enables to build complete information of obstacle and reckon reasonable position. According to LiDAR erected on the roof, if the distance between the vehicle and obstacle is shorter than 2m, as shown in Figure 8 (c), a blind area generates. Moreover, the system applies ultrasonic wave radar to detect the surrounding of vehicle and calculate relative position. Furthermore, the system with LiDAR information establishes in the same three-dimensional coordinate space for compensating blind area problem.

A line camera based lane following intelligent vehicle control system is an idea to satisfy the autonomous racing car for the Freescale™ cup. The Freescale™ cup is a global competition where student teams build, program, and race a model car around a racing track for speed without derailing from the track. This competition is believed to be a platform for the participants from around the globe to access to the latest technology and apply it by hands on.
To increase the overall efficiency of the photovoltaic (PV) system we employ a SEPIC converter, because the output voltage from the solar panel is fluctuating and variable DC which cannot be stored in a battery. Hence this fluctuating DC has to be converted into stiff DC with the help of a DC-DC converter. If the output voltage has to be increased, we use a boost converter else we require buck converter. In the case of a photovoltaic system we sometimes need to increase or reduce the output voltage, hence a buck boost converter can be used. But buck boost converter has certain disadvantages such as poor transient response, need of a filter in the input side, high peak current etc. Thus we use a SEPIC converter which can increase or lessen the output voltage of the photovoltaic system. The block diagram of a SEPIC converter shows that it employs two inductors L1 and L2, three capacitors Cin, C1 and C2, a switch S1, a diode D and a resistive load R which are connected in series and parallel. The capacitor Cin is used as a filter capacitor, C1 as coupling capacitor and C2 as decoupling capacitor.
The ESR impacts the output voltage ripple and the overall efficiency of the converter. Because of this, designers are moving to low ESR designs. Surface mount ceramic capacitors are becoming prevalent in systems that require high performance in a small form factor. The choice of multiple capacitors connected in parallel allows designers to achieve the necessary capacitance for the system while greatly reducing the equivalent ESR.
V. C ONTROLLER D ESIGN U SING SIMULINK The observer controller design takes into consideration that not all states can be sensed and there for the addition of an observer is needed in the system. This addition requires an additional loop in the controller and a second loop gain, the observer gain, L. The observer gain design is theoretically independent of the controller feedback gain design (K). However, in this case the gain, L, was calculated by pole placement based on the closed loop poles of the controller system with the gain K. The best system performance was achieved by placing the observer gain poles to be equal to the negative of the smallest magnitude of the real component of the closed loop controller poles.

Modeling and simulation of the intended system are indispensable for design and analysis using either analogue and/or digital computers/processors. The first problem facing the designer in simulating a missile guidance system is the translation of its tactical characteristics into design specifications. These specifications carried out through a complete set of equations representing the missile motion and yielding the mathematical model . This model constitutes the six degrees of freedom (6DOF) equations, which break down into those describing kinematics, dynamics (aerodynamics, thrust, and gravity), command guidance generation systems, and autopilot (electronics, instruments, and actuators) . The input stimuli to this model are launch conditions, target motion, and target trajectory characterization and the outputs are the missile flight data (speed, acceleration, range etc.) during an engagement. Conducting the flight simulation helps to draw contributions about the reliability of conceptual hardware design and its effectiveness with minimum cost and no need for the very expensive flight trials, especially at the starting phase .
“Surveillance system using phone line for security and tracking ”. Based on the above statement, it is targeted that this project will serve as good indication of how important it is to curb car theft in the country. Surveillance is specified to car alarm system and the means of sending the data to the owner of the vehicle using SMS when the alarm is triggered. Due to the inefficient conventional car security system, the possibility of the car can be stolen is high. The main reason is that the alarm is limited to the audible distance. Somehow if there is another way of transmitting the alarm to the car owner ,tracking the vehicle ,knowing the exactly that the car is been stolen at the same time that is not limited to the audible and line of sight, the system can be upgraded. SMS is a good choice of the communication to replace the conventional alarm, because it can be done and does not require much cost. Although most of people know GPS can provide more security for the car but the main reason people does not apply it because the cost. Advance car security system is too expensive. Cost for the gadget is too high. Beside that, people also must pay for the service monthly. Tracking systems were first developed for the shipping industry because they wanted to determine where each vehicle was at any given time. Passive systems were developed in the beginning to fulfill these requirements. For the applications which require real time location information of the vehicle, these systems can’t be employed because they save the location information in the internal storage and location information can only be accessed when vehicle is available. To achieve automatic Vehicle Location system that can transmit the location information in real time. Active systems are developed. Real time vehicular tracking system incorporates a hardware device installed in the vehicle (In- Vehicle Unit) and a remote Tracking server. The information is transmitted to Tracking server using GSM/GPRS modem on GSM network by using SMS or using direct TCP/IP connection with Tracking server through GPRS. Tracking server also has GSM/GPRS modem that receives vehicle location information via GSM network and stores this information in database. This information is available to authorized users of the system via website over the internet.
