The invention discloses an automobile OTA upgrade power supply mode switching system and method, and belongs to the technical field of automobile electronics, the switching system comprises an OTA cloud server, a TBOX, a BCM controller and a to-be-flashed ECU; the OTA cloud server is used for storing an OTA upgrade package and deploying an upgrade task; the vehicle end TBOX is in communication connection with the OTA cloud server and is used for downloading an upgrade package from the OTA cloud server and sending a remote control encrypted message to the vehicle body controller BCM; the BCM is used for switching a power supply mode; flashing is carried out in the power-on mode, and power-off is carried out after flashing. According to the system and the method, the encryption of the remote control message is realized, and the security of communication is ensured. And the power supply mode of the whole vehicle is IG ON in the flashing process, and the user can be notified to upgrade task related information in the mode.

    本发明公开了一种汽车OTA升级供电模式切换系统及方法,属于汽车电子技术领域,所述切换系统包括OTA云服务器、TBOX、BCM控制器及待刷写ECU;所述OTA云服务器,用于存储OTA升级包及部署升级任务;所述车端TBOX,与OTA云服务器通信连接,用于从OTA云服务器上下载升级包、向车身控制器BCM发送远控加密报文;所述车身控制器BCM,用于供电模式的切换;在上电模式下进行刷写,刷写后下电。该系统及方法实现了对远控报文的加密,保证了该通信的安全性。且在刷写过程中整车供电模式为IG ON,该模式下可以通知用户升级任务相关信息。
