摘　　要：针对电动汽车动力系统的通信特点,该文设计了包含电机控制器(MCU)、整车控制器(VCU)、电池管理系统(BMS)和仪表(HEC)4个节点的CAN总线型通信网络;基于SAE J1939协议,系统介绍了制定电动汽车动力系统CAN网络应用层协议的流程;利用CANoe软件搭建了动力系统CAN网络模型并进行了仿真测试;通过CANoe硬件接口连接真实的通信节点进行硬件在环测试。结果表明制定的应用层协议是可行的,设计的CAN网络工作正常,具有良好的实时性和可靠性。According to the communication characteristics of electric vehicle power system,the CAN bus network including motor controller unit（MCU）,vehicle controller unit（VCU）,battery management system（BMS）and display instrument（HEC）is designed. Systematically introducing the process of CAN network application layer protocol for electric vehicle power system based on SAE J1939 protocol. The model of this network is set up by CANoe software,and the simulation of it is carried out. Hardware in the loop test is performed by using the CANoe hardware interface to connect the real communication nodes. The results show that the application layer protocol is feasible,the state of CAN bus communication network is normal,and possesses a good quality of real time and credibility.
