ABSTRACT
FlexRay, developed by a consortium of over hundred automotive companies, is a real-time communication protocol for automotive networks. A communication cycle in FlexRay consists of an event-triggered component known as the dynamic (DYN) segment, apart from a time-triggered segment. Predicting the worst-case response time of messages transmitted on the DYN segment is a difficult problem. This is because a set of complex rules, apart from the priorities of the messages, govern the DYN segment protocol. In this paper, we survey techniques for the timing analysis of the DYN segment. We discuss the challenges associated with the timing analysis of the FlexRay protocol, the proposed techniques and their limitations.
