The invention relates to vehicle ECU remote upgrading equipment and a vehicle ECU remote upgrading method, and provides a method for realizing vehicle ECU remote upgrading based on a UDS communicationprotocol in allusion to the current situation that different vehicle factories need to independently develop respective vehicle ECU remote upgrading systems. The method is based on CAN communicationdata of a vehicle. A vehicle UDS diagnosis protocol and a remote monitoring platform scheme are compiled; remote data upgrading of the vehicle ECU is achieved through the hardware vehicle-mounted terminal 4G module, manual offline upgrading of the ECU is not needed any more, the upgrading time of the vehicle ECU can be set at the background, and the ECU is upgraded automatically through remote networking after the set time is up. An ECU delivery recovery mechanism is specified in the UDS protocol, and the situations of ECU crash damage, data loss and the like caused by networking failure in the upgrading process are avoided. By establishing the cloud platform, the vehicle-mounted hardware and the data management algorithm and combining the UDS diagnosis protocol for encryption security access, ECU upgrading is safer and more convenient.

    本发明涉及车辆ECU远程升级设备及方法,针对不同车厂需独立开发各自的车辆ECU远程升级系统的现状,提供一种基于UDS通信协议实现车辆ECU远程升级的方法。本发明基于车辆的CAN通信数据,编制出车辆UDS诊断协议和远程监控平台方案,通过硬件车载终端4G模块实现远程对车辆ECU的数据升级,无需再通过人工手动线下升级ECU,可以在后台设定车辆ECU升级时间,到达设定时间后ECU自动通过远程联网进行升级。UDS协议中规定了ECU出厂恢复机制,避免了升级过程中出现联网失败造成ECU死机损坏、数据丢失等情况。本发明通过建立云端平台、车载硬件和数据管理算法,结合UDS诊断协议进行加密安全访问,让ECU升级更加安全便捷。
