Fraunhofer demos tool chain for fail-operational cars

February 05, 2016 // By Christoph Hammerschmidt
Highly automated driving presupposes that the vehicles are capable of tolerating system errors until the driver is ready to intervene. Towards this end it is necessary that in the on-board systems the failsafe performance of critical functions be guaranteed. Fraunhofer ESK has created a tool chain developers can use to achieve this goal – based on the Autosar standard.

Within the EU project SafeAdapt, the Munich-based research institute has investigated methodologies and solutions that enable automotive developers to implement failsafe architectures. It was an important subgoal that these architectures can be implemented on a variety of ECUs and in heterogeneous environments. The way this subgoal has been achieved was integrating the design tools into an Autosar-compliant tool chain. Thus, the ESK concept enables automated ECU software generation. The researchers claim that this is the world’s first Autosar compliant solution for future electronic on-board networks with fail-operational behaviour as needed for future degrees of automated driving.

The researchers will showcase their solution at the upcoming Embedded World in Nuremberg, Germany. Using the example of a steer-by-wire steering, the researchers will demonstrate how such fail-operational E/E architectures can be implemented with the current Autosar Classic platforms. The demonstrator shows how the development process is structured and how the system functions. A model car with control units that are connected with a drive simulation will take centre stage.

The exhibit has been developed within the SafeAdapt research project. First evaluation results will be available in the middle of the year. Project partners include Fraunhofer ESK, CEA LIST (France), Delphi (Germany), DuraCar (The Netherlands) Fico Mirrors (Spain), Pinifarina (Italy) and TTTech Computertechnik (Austria).
