0% of innovations are Electronics and Software

Incar SW increase by the power of 10 every 5-7 year

So in this context, How do we develop software ?

Autosar – the automotive sw arch standard

Standardized SW platform

Configured by xml-specs of application swc:s and

ECU descriptions.

Function specific applications

Standardized formal description of SW components

including I/F, CPU, memory, timing, etc.

Auto generated middleware from xml-specs

AR is de-facto for RT-systems.

There is also a candidate for

the Infotainment domain,

called Genivi.

Model fidelity accurate enough to

also evaluate mechanics!

• Separation of plant models and

controllers (reusability)

• Common architecture for MIL, SIL,

HIL, rigs

• Complete vehicle view; physical

and functional oriented

• Support for different simulation

environments and tools – enabling

multi-domain simulation

• Structural approach to define test environments in terms of sw components and

physical plant models.

• Layers of backlogs to control and manage weekly deliveries and maturity

growth.

• Still huge improvements needed, to efficiently manage the increasing

complexity without being infinite complicated. SAFe(?)

• As long as SW complexity increase, PMTs will always be a step behind.

- And that’s why it’s so fun to work with



prototype in disguise integrates all

aspects at once, big bang!

Lab (virtual) typically separates

• Electrical Integration

• Functional integration

• Mechanical integration

• User integration
