摘　　要：在分析车载CAN网络诊断协议与车载网络诊断结构的基础上,设计基于ISO15765的车载网络诊断,采用VC软件开发平台及USBCANII硬件接口,实现诊断工具的设计与开发。测试结果表明,该诊断系统的通信过程符合诊断协议,在开发与测试支持诊断功能的ECU过程中得到较好应用。On the basis of the research and analysis of CAN network diagnostic protocol and automotive diagnostic structure, in-vehicle network diagnosis is designed and developed. The design and development of diagnostic tool is realized through VC software development platform and USBCANII hardware interface. System test result shows that communication process of the designed diagnostic system conforms to diagnostic standard. The developed low cost diagnostic tool is applied well on developing and testing ECU with diagnostic function.
