摘要
研究了CAN总线在CVT控制系统中应用。针对目前比较流行的高层协议如CANopen、DeviceNet、SAEJ1939、SDS等,用于节点较少的CAN网络时会造成不必要的资源浪费的缺点,在分析了TMS320F2812内嵌的eCAN模块的基础上,提出了一种简单、可靠且实用性较高的CAN高层通信协议,并完成了相关的软、硬件设计,实现了CVT控制系统与汽车上其它ECU的数据通信。该通信协议也为汽车CAN网络节点间的通信提供了借鉴。
The study of the applications of CAN bus in the CVT controlling systenu To avoid the unnecessary waste which may be caused when the popular high-layer protocol,e.g. CANopen,DeviceNet, SAE J1939,SDS applied in CAN network with few knobs ,the eCAN module was analyzed,a simple,reli- able and practical high-layer CAN communication protocol was developed and the relevant hardware ＆ software was designed. Moreover,the communication between CVT controlling unit and other ECUs was realized. The study of the protocol lays the foundation of the communications between ECUs in car＇s CAN network.
