Based on the automotive open system architecture (AUTOSAR) specification of FlexRay bus, this paper designs the FlexRay bus communication protocol stack. With the development of rail vehicles, the driving safety, driving comfort and passenger comfort of rail vehicles have been significantly improved. Accordingly, the number and the complexity of electronic control units (ECUs) are increasing, and the amount of software code is rising rapidly. However, the bandwidth and data volume of controller area network (CAN) bus are relatively limited, and its fault tolerance and reliability are relatively low. It will be difficult to meet the requirements of future vehicle network control. FlexRay bus replaces CAN bus, which has higher bandwidth and better fault-tolerant performance. At the same time, the communication protocol stack conforming to AUTOSAR specification can shorten the software development cycle of electronic control system for railway vehicles, reduce the labor cost of products and improve the software portability rate. Experimental results verify the feasibility and validity of the protocol stack.
