摘要
随着综合电子系统总线网络的发展以及特种车辆自身设计的需要,越来越多的车辆需要两种或多种总线系统实现内部不同分系统之间的数据交互;为实现CAN和FLexray两种总线数据交互目的,结合CAN总线与Flexray总线的不同协议特性进行由浅入深的分析研究,并采用具有CAN和Flexray协议控制器的Freescale芯片进行了硬件设计、软件流程设计和具体的函数开发,最终实现了针对某种车辆应用的总线网关设计;从中总结了进行CAN/Flexray网关开发所要求具备的先决条件和主要注意事项,对相关类似研究开发具有重要借鉴意义。
With the development of integrated electronics systems bus networks and the need of self--design of special vehicle, more and more vehicles need realize data transfer among different sub-- systems by two or more buses. In order to realize the purposes for data transfu- sion between CAN and Flexray bus, make research and analyse based on the Communications System Protocol Specification of FlexRay and CAN bus from superficial to depth. Have design about hardware, software and function developing based on one chip from Freescale Which include CAN and Flexray bus Protocol controller. Bus gateway have be achieved and applied in view of some vehicle finally, it summarize preliminary requirements and which items should pay attention to about designing of CAN/Flexray gataway, which have important reference value for similar research or development.
