FlexRay networks for SAE benchamrk application using DDS middleware: Development of FlexRay driver and its Simulink Blockset implementation

Abstract

FlexRay networks is known as one of the newest x-by wire communication systems [1] thanks to its several features such as flexibility, fault-tolerance, determinism and high-speed. It is known for their speed and performance insuring communication over a shared medium since it offers reliable and real-time capable high-speed data transmission between electrical and mechatronic components. In the same context, the real-time middleware Data Distribution Service (DDS) is an appropriate alternative for the standard vehicular middleware. In this paper, we focus our interest on the development of FlexRay Driver and the Simulink Blockset implementation of its Driver in order to validate its performances and design and to provide current and future innovative functions into distributed systems within automotive applications. The proposed blockset is dedicated for the SAE(Society of Automotive Engineers) application. The SAE benchmark model is normally connected by the CAN bus we extended it to the FlexRay Bus. We have applied the real-time middleware Data Distribution Service (DDS) in order to guarantee the QoS of SAE benchmark using the FlexRay protocol.
