Bus Systems in Automobiles
Bus systems in automobiles allow the communication, which means the exchange
of data between the electronic control units (ECUs), smart sensors and actuators.
Depending on the respective requirements, different bus systems are used. Typi-
cal requirements consist of required data rate, allowed message length, number
of connectable nodes (ECUs), required topologies, requirements on deterministic
transmission capability and in further reliability, availability or safety-oriented re-
quirements. Further requirements address aspects of physical characteristics, like
tolerance against voltage deviations, temperature stability, impacts on wiring har-
ness (electromagnetic compatibility (EMC), copper wire, plastic or glass fibre,
