Marker following group: BackgroundValue Chain: Mechanics -> Embedded Systems



Data dependencies between all components; Functions are spread across ECUs (G. Spiegelberg, Siemens AG)

Example: automatic engine start-stop systems o Affects ~30 ECUs , functions spread across ECUso High complexity of communication and design processes

“Hard wired” architectures with distributed ECUs Dedicated bus systems with different transport

parameters and service qualities




Marker following group: BackgroundState-of-the-art automobiles have about 70 (partly over 100) ECUs, with

limits reached in - Weight - Space (size of car)- Cost- Cables and connectors
