摘要: Driven by the increasing demand for high speed communication of in-vehicle automotive systems, car manufacturers and suppliers have developed FlexRay protocol. Being dedicated to safety time-critical applications, availability appropriate timing analysis methods prediction behaviour is essential. Consequently, several solutions been proposed. Due limitation in number frame identifiers dynamic segment, slot-multiplexing (or cycle-multiplexing) mechanism gaining importance realistic systems. This allows share between messages. Moreover, cycle multiplexing segment often used signals with deadlines beyond signal period. Despite its practical relevance, none existing response-time approaches able consider configurations. In this paper we overcome limitations previous work present a more general approach which accurately takes into account. We illustrate applicability proposed an industrial case-study synthetic testcases.
