Résumé :
[en] Software defined vehicle puts the challenges not only on the computing systems in the vehicle but also on the network. To design a system that can exhibit the required level of determinism for a set of distributed control applications, it is not enough to have a network that is predictable from the timing perspective, one also needs proper real-time scheduling mechanisms in the operating system and in the communication stack, i.e. the interface between the application and the network. In this contribution, we present:
- Overall concept, or what do we mean with a time-predictable system,
- State of the art in deterministic real-time Ethernet communication,
- The real-time scheduling mechanisms commonly used in Automotive,
- Examples of challenging issues and practical use cases that OEMs need to address toward timing predictability in the system.
