摘要
分析了使用于车内安全性和实时性相关系统的FlexRay通信协议规范,并以线控转向模型的通信系统为例介绍在开发FlexRay总线通信集群过程中的三个步骤:通信模型仿真,节点ECU软硬件设计和系统整合。最后在系统整合的过程中,将开发的FlexRay节点替换掉通信模型中的仿真节点,利用CANoe.FlexRay和具有FlexRay协议分析功能示波器对通信的时序和波形物理特性进行测试和分析,以此验证本文所设计的FlexRay通信集群满足设计需求并符合FlexRay通信协议规范。
The features of the FlexRay communication protocol specification are introduced in this paper,which will be used in safety-critical and real time system.Then describe the three steps to build a FlexRay communication cluster for Steer-by-Wire based on CANoe.FlexRay:modeling and simulating,hardware and software design for FlexRay node and system integration. During the process of system integration,the measurement and test environment for the FlexRay bus communication schedule and physical characteristics is described.Finally,ion cluster development.
