Research on the Control Unit for Automobile High Speed Communication Network

为拓展FlexRay总线在各种复杂网络中的应用,针对FlexRay总线开发流程复杂的问题,采用飞思卡尔公司的微控制器和恩智浦公司的收发器,设计了满足FlexRay通信协议的节点最小系统。该系统提供扩展接口,可满足实际需求。实践表明,该系统能够实现两节点间数据的高速通信,符合设计要求,为实现更复杂的网络通信提供了参考。

In order to expand the applications of FlexRay bus in various complex networks, and aiming at the problem of complexity of development process of FlexRay bus, a node minimum system satisfying FlexRay communication protocol is designed by using Freescale microcontroller and NXP transceiver. The system provides an extended interface to meet the expansion needs, which has practical value. The practice shows that the system can realize high speed communication between the two nodes, meet the design requirements, and provide reference for implementing more complicated network communication.
