摘要:

J1939协议是目前在大型汽车中应用广泛的通信协议,被应用于以CAN为基础的嵌入式网络中。阐述了J1939协议和CAN的对应关系,介绍了在ECU通信中的功能应用、通信过程及数据包组织方式,以及常用参数组含含义,并给出示例说明通信过程。通过对J1939协议使用的介绍有效推进了J1939协议在汽车行业的发展和应用。

关键词: J1939, CAN, 通信, 数据包, 参数组

Abstract:

J1939 protocol is a communication protocol widely used in largescale automobiles currently.It is applied to the embedded CANbased networks.This paper mainly expounds the relationship between the CAN and J1939 protocol,focusing on details of the function application in the ECU communication,the communication process and how to organize data packets.It also describes the meaning of the commonly used parameter set and gives examples to explain the communication process.Detailed instructions on how to use the J1939 protocol effectively promote the further development and application of J1939 protocol in the automotive industry.

Key words: J1939;CAN;communications;data packets;parameter set
