Course: FlexRay in automotive

Any introduction to motor vehicle electronics will inevitably have to cope with the ever more complex network interconnection in today's models. This involves sensors, actuators and control units, as well as entertainment and navigation equipment. FlexRay is the most important communication system for drive-by-wire and other such interconnected networks. The primary requirements for such systems are higher data transmission rates, deterministic communication, high fault tolerance and flexibility. This UniTrain course covers the subject of FlexRay in a way which closely reflects authentic modern practice.
