FlexRay is a hybrid in-vehicle communication protocol for automotive networks, which handles time-triggered messages in static segment as well as event-triggered messages in dynamic segment. In this paper, we study the problem of holistic scheduling of time-triggered tasks and messages in FlexRay. Our solution is based on synchronous scheduling between tasks executions and message transmissions, and supports slot multiplexing as defined by FlexRay V3.0 specification. Our objective is to obtain an optimum schedule with respect to minimizing used bandwidth, subject to FlexRay specifications and delay requirements. We demonstrate the efficiency of our approach using case studies consisting of an X-by-wire system on actual prototype vehicles.
