New driver assistance systems on their way to automated driving are pushing the currently available E/E architectures to the limits. On the one hand, this applies to the domain and ECU topology, which will be extended by additional components, e.g., for environmental sensing, data processing, automated vehicle control and for the required surround view. On the other hand, redundant communication and system functions are necessary to ensure a “fail-degraded” or “fail-operational” system behavior. These redundancy requirements also apply to the vehicle power supply so that a redundant power supply is available to ensure that the braking system and steering system remain available even in the event of failure.This paper introduces an E/E architecture proposal for Commercial Vehicles (medium & heavy duty) which supports the automated driving functions such as Traffic Jam Pilot, Highway Pilot and Pairing/Platooning1 and discusses the necessary redundancy concepts for communication, system functions and power supply.Technological enablers for economic implementation of the necessary redundancies, as well as zone-based structures based on central communication backbones and energy backbones, are also proposed that offer potential for simplifying wiring harnesses available today.Since connecting the vehicle to the Internet and to other vehicles or to the vehicle environment is also part of automated driving systems, such as Pairing for instance, a multilevel security concept for automotive applications is also presented that secures the vehicle against external attacks and provides multi-level security to the functions and communication in the vehicle. The resulting structural requirements on E/E architectures are also represented.
