Architecture and System Safety Requirements for Automated Driving

Driver assistance systems have been successfully deployed to the market in the last fifteen years resulting in an increase of driving comfort and driving safety. In the future, these systems will be able to analyze ever more complex traffic situations and to support the driver or even act independently. Upcoming functionality will lead to partially automated driving, highly automated functions will follow soon after. With the increase of automation the role of the driver is going to change gradually from an active driver to a passenger at least for some duration of the drive. We discuss the implications of this evolution on the requirements for future vehicle architectures. In particular, we discuss the electric on-board power supply of critical driving components for longitudinal and lateral vehicle guidance and derive system safety and architectural requirements.
