The combustion engine will be the dominant drive for motor vehicles despite all the advances in the electrification of the drive train, for many years. The greater are the challenges for the automotive industry, especially in fuel consumption (CO2) and the environmental impacts of other emissions. From the fuel supply to the engine, up to the exhaust after treatment, new or improved functions are needed, which are integrated into increasingly powerful control electronics. This modern electronic engine management and powertrain controller will remain key components in the vehicle.As most of the micro controllers for future applications will be MultiCores, this paper gives an overview on how PowerSAR® supports this kind of architectures. It shows the concepts applied in the basic software area as well as for the applicative software. Further it will show the impact on the development process as well as the integration support for software delivered by the OEM.This work will give an outlook on upcoming micro controller architectures and the new challenges in the future in this domain.
