摘　　要：文章针对当前汽车存在软硬件故障频发、故障发生时数据无法即时获取、问题复现和原因定位困难等问题,基于物联OMA-DM协议,结合车载Tbox和互联网技术,设计了一种车辆远程诊断系统。该系统可以通过Web页面配置和下发诊断任务,实时监控车辆运行状态,记录故障促发前后的车辆总线数据以及相关诊断数据,并通过车端Tbox将数据上传至云服务器后台,为故障分析定位提供帮助。In view of the current problems of frequent software and hardware failures,the data cannot be obtained immediately when the failure occurs,difficulty in problem recurrence and locating the cause and so on,a vehicle remote diagnosis system is designed combined with on-board Tbox and Internet technology based on IOT OMA-DM protocol.The system can configure and issue diagnostic tasks through Web pages,monitor the vehicle real time running status,and record the vehicle bus data and relevant diagnostic data before,during and after the issue happened.And the system can upload the data to the cloud server background through the vehicle end Tbox to provide help for fault analysis and location.
