汽车凭借其机动灵活、可达性强等特点,成为了现代生活中的首选代步工具.针对汽车电控系统日趋复杂、故障小且隐蔽的问题,将汽车的监测和诊断与智能手机相结合,以智能手机取代传统诊断仪器,利用蓝牙通信从汽车的OBDⅡ诊断接口获取汽车的状态数据和故障信息,并通过Internet技术将数据传输到远程服务器.在本地以手机和用户进行交互,远程以Web浏览器作为显示终端.这样不仅解决了时间和空间对汽车故障诊断的限制,而且对构建车联网和实现车与人之间的信息互联都具有很重要的意义.%With its flexibility , high accessibility , the automobile has become the preferred tool of transportation in modern life .Combining the monitoring and diagnosis of automobiles with the smart phone for the increasingly com -plicated and small fault of the automobile electronic control system , it replaces the traditional diagnostic instrument with a smartphone , uses Bluetooth communication from the OBDⅡdiagnostic interface of the car to obtain the vehi-cle's state data and fault information , and through the Internet technology to transfer data to the remote server .In the local, the user uses the phone to interact;in the remote, the Web browser is the display terminal .This will not only solve the limitation of time and space on vehicle fault diagnosis , but also be of great significance for the con-struction of vehicle networking and the realization of inter vehicle information communication .
