摘要

With the development of automotive electronics, more and more people use the wire control technology to overcome the defects of the traditional mechanical equipment and the hydraulic control system and to improve the handling stability, safety and comfort of the vehicles. FlexRay bus is a new advanced communication technology that aims to control the vehicle speed, and it has already been used in the concept vehicle. In order to further explore the potential of FlexRay when applied in the automotive industry, in this paper, we focus on the FlexRay communication module of the Steer-by-wire (SBW) System, and analyze and improve the complex part or deficiency of the protocol. Finally, we make the module’s communication function be well enough to ensure the real time and fault tolerance function of the SBW system. Through the monitoring of communication controller and bus monitor scheduling, we could make sure that the node only get access to the bus at the correct point, thus to provide theoretical basis of achieving bus monitoring capacity for the FlexRay.
