摘　　要：控制器局域网络(CAN)通讯协议在自动化及工业控制领域有着极为广泛的应用。在现代汽车电气结构中,将微控制器、传感器、执行器通过CAN总线连接起来,已经成为一个显著的特点。在分析了CAN通讯协议及SAEJ1939标准的基础上,以NECV850系列32位微处理器70F3239为主控芯片,完成了电动汽车控制器CAN模块的开发工作,实现了与其它车载控制器之间基于CAN的连接,并且完成了CAN报文收发的软件设计。Controller Area Network （CAN） protocol has been widely applied in the field of automation and industry control. Connecting microcontrollers, sensors and actuators within the electronic architectures of modern vehicles based on CAN protocol has become a remarkable characteristics. According to the analysis of CAN protocol and SAE J1939, the development of CAN module of electric vehicle （EV） controller was accomplished in NEC V850 70F3239 microprocessor. The module realized the communication with other invehicle controllers through CAN bus. Meanwhile the software of CAN message transmission and reception was designed.
