When creating a software upgrade task, selecting the corresponding vehicle controller's workstation is actually confirming the VIN of the corresponding OTA main control unit. After the software upgrade task is successfully created, the OTA main control unit will query whether there is a software upgrade task on the OTA cloud server. After querying the software upgrade task, it will first read the vehicle controller information of the corresponding workstation according to the OTA process and feedback it to the OTA cloud server. The OTA cloud server generates a software upgrade package for the corresponding vehicle controller. The OTA main control unit will download the software upgrade package generated by the OTA cloud server and feedback the download progress information to the OTA main control unit.

[0079] S303: The master control unit sends a confirmation upgrade instruction. After confirming that the software upgrade package has been downloaded, the master control unit sends a confirmation upgrade instruction to the OTA master control unit.

[0080] S304: The vehicle controller starts to upgrade. After receiving the upgrade confirmation instruction, the OTA main control unit starts to control the vehicle controller upgrade as a host computer.

[0081] S305: Feedback of software upgrade results to the master control unit. After the vehicle controller upgrade is completed, the OTA master control unit will feed back the software upgrade results to the OTA cloud server. The master control unit will parse the software upgrade results of all vehicle controllers on the OTA cloud server and output them to the user on the program interface.
