汽车远程诊断技术研究

Research on Automobile Remote Diagnosis Technologies

随着5G通讯技术的快速发展,远程诊断技术逐渐成为汽车领域诊断技术发展的主要方向。远程诊断架构主要包括车端、云端、车云通讯协议3部分,云端主要实现ODX、OTX文件的编辑和推送,通过车云协议发送到车端执行,同时车端将诊断运行反馈给云端。远程诊断技术的应用,使操作者不必在车辆现场仅通过远程技术手段就能对车辆进行诊断,解决了对车辆实时性诊断的需求。

With the rapid development of 5G communication technology,Remote diagnosis is becoming the main method in the vehicle diagnosis technology domain.Remote diagnosis architecture includes vehicle side,cloud side and the transport protocol between them.The cloud side includes the ODX,OTX file edit and diagnostic assignment,which are pushed to the vehicle side by the vehicle and cloud protocol,the vehicle returns the diagnostic feedback to cloud.The Application of remote diagnosis technology makes the user easy to achieve vehicle diagnosis that meets the need about real time diagnosis and the future big data analysis development based on it.Remote diagnosis technology also provides the necessary technical method about the full period monitoring vehicle health.
