摘要
CAN总线的应用体现了电控系统优势,优化了整车性能。在某一自主研发的重型卡车上应用了CAN总线,采用J1939协议,连接发动机、ABS、组合仪表以及安全气囊,通过网络进行控制和信息交流,大大的提升了整车性能。通过对J1939协议的研究,对各节点的发送报文进行了定义。通过对ABS/ASR的控制过程的研究确定其同发动机通讯的控制时序和报文发送的数据。同时结合开发流程设计了三个步骤的测试方法。
CANbus exert advantage that electronic control system and optimize vehicle capability,CANbus has application in selfdevelopment heavy truck,used the SAEJ1939 communication protocol,connect engine,ABS,dashboard,air bag control module, use network to control and information communication,advance vehicle capability.With the research to J1939,defines each node transmit message.With the research to ABS/ASR control process,decide engine control time schedule and message data.For test network communication and capability.
