Abstract: This paper studies the advantages of FlexRay bus, application layer communication protocol and their application in all-electronic execution system. FlexRay bus is used as the internal network scheme of the system, and the hardware platform is constructed based on TMS570LS3137 processor. The main control units in the system are used as FlexRay nodes to communicate through the bus topology. A concrete implementation scheme is proposed in this paper, and the technical key points of FlexRay communication nodes in hardware and software design are discussed, which is helpful to the realization of data security communication transmission in the system.

Key words: FlexRay bus, TMS570LS3137, all-electronic execution system
