摘　　要：提出了基于车载总线的PC式汽车故障诊断系统的设计思路,依据ISO/OSI网络模型,将整个系统划分为应用层、协议转换层、物理层,以及应用协议接口和链路物理接口的模块化&层次化体系结构。整个系统由PC诊断应用软件、VCI盒和车载网络组成,着重阐述了系统的软硬件设计方案。通过某公司全车系实车测试表明,该系统在满足基本的故障诊断功能基础上,兼具数据处理、存储和图形显示功能,具有系统升级及远程诊断扩展的优势。PC-style car fault diagnosis system based on-board bus was proposed.According to ISO/OSI network model,the whole system was divided into application layer,physical layer,modular and hierarchical system structure of application protocol port and link physical port.The system was composed of PC diagnostic software,VCI boxes,vehicle network.The corresponding software and hardware design were conducted.The vehicle testing indicates that in addition to the basic fault diagnosis,this apparatus has the advantages of data processing,storage,graphics display,system upgrades and expansion of remote diagnosis.
