摘要
FlexRay是能够满足未来车内控制应用需求的通信系统。它采用了基于时间触发的数据传输技术,相对于当前在车内广泛采用的基于事件触发的通信总线(如CAN等),其应用开发方法有很大不同。为了阐明基于FlexRay总线的应用开发过程,使用DecomSys公司的分布式系统开发工具Designer软件设计了基于FlexRay总线的线控节气门原形控制系统。介绍了系统的体系结构、任务模型的构建以及应用开发过程,并对FlexRay在该系统中的应用进行了分析。
FlexRay is a communication system that will support the needs of future in-car control applications.The media access scheme of FlexRay is based on time-triggered technology,which makes its application development method different to that of the event-triggered bus （such as CAN,etc）,which is widely applied in car currently.In order to illustrate the application development method based on FlexRay,a throttle-by-wire prototype control system based on FlexRay is designed in this paper using DecomSys： ：Designer,which is a comprehensive development tool for distributed systems.The system architecture,task model,and the application development procedures are described.Finally the application of HexRay in this system is analyzed.
