摘　　要：针对目前汽车故障诊断设备通常需要单独硬件支持并且扩展性、便携性较差等问题,在如今智能手机日益普及的环境下,通过分析车载CAN网络诊断协议ISO15765以及UDS统一诊断服务,提出建立可跨平台与车系的诊断数据库。设计蓝牙通信模块并在此基础上基于iOS平台开发汽车故障诊断软件,实现便携式的汽车故障诊断。通过在实验平台上的测试结果表明,所设计的汽车故障诊断仪能够准确诊断和解析汽车ECU中的故障,实现不需要额外硬件成本仅利用移动终端完成的汽车故障诊断与定位。Considering the problems that current vehicle fault diagnosis instruments usually need to be supported by sole hardware,and have poorer scalability and portability,etc.,we put forward to establish the cross-platform and car series diagnoses database under the environment of increasing popularity of smartphone and by analysing the vehicular CAN network diagnosis protocol ISO15765 and UDS (uniform diagnostic services).We also designed the Bluetooth communication module,and on this basis we developed the vehicle fault diagnosis software based on iOS platform,implemented the portable vehicle fault diagnosis.It was demonstrated through the results of test on experimental platform that the designed vehicle fault diagnosis instrument could accurately diagnose and resolve the faults in car’s ECU,and achieved the vehicle fault diagnosis and positioning without extra hardware cost by only using mobile terminals.
