摘　　要：为了研究电动公交客车上CAN总线网络节点信息的实时性及可靠性问题,依据CAN总线网络通讯协议技术的特点,研究并设计了一种电动公交客车的CAN总线网络通讯结构,并给出了适用于电动公交客车的SAE J1939应用层协议及汽车CAN总线网络的硬件接口模块,软件模块采用了基于优先权竞争的模式,通过CAN总线网络和基于优先权模式的方法,实现了实时采集、分析、处理电动公交客车的各个数据节点的信息和数据.最后,在路况测试中通过对实际数据的采集,验证了电动公交客车CAN总线网络通讯结构的硬件、软件模块设计合理,具有实际的学术价值和应用前景.In order to research the study on the real-time and reliability of the CAN BUS informations on electric vehicle, this study designed a structure of CAN BUS network communication for electric vehicle based on the characteristics of CAN BUS technology and an application layer protocol of SAE J1939 for electric vehicle and the hardware modules. The software modules used the priority-based of the right mode of competition to ensure the system＇s real-time and reliability. Through the actual data collection on road, the hardware circuits and the software design are reasonable. So the designed of CAN BUS network communication structure for electric vehicle has practical application value.
