This enables the vehicle-mounted system to skip the upgrade judgment conditions and directly upgrade the firmware.

Step S304, receiving the first upgrade data and the first upgrade instruction sent by the detection end.

During specific implementation, after receiving the first upgrade instruction, the upgrade file corresponding to the component to be upgraded (that is, the ECU to be upgraded in the HMI) and the original component to be upgraded is determined through the upgrade list in the first upgrade data, and the specific operation is to analyze and fix The manifest.json file in the address, you can know which ECUs need to be upgraded, which is the corresponding upgrade file for each ECU, and the upgrade sequence of each ECU.

Step S305, perform firmware upgrade for each unit to be upgraded according to the first upgrade instruction and the first upgrade data.

During specific implementation, use the upgrade files determined in the above steps to upgrade the firmware of the components to be upgraded determined in the above steps, that is, upgrade the ECUs in sequence according to the upgrade sequence configured in the manifest.json.

Step S306, generating upgrade result information according to the upgrade result, and sending the upgrade result information to the detection end.

When generating the upgrade result information specifically, if the firmware upgrade fails, an upgrade failure list is added to the upgrade result information, and the upgrade failure list is used to make the detection end determine the unit that failed the upgrade; if the firmware upgrade is successful, the detection is notified through the upgrade result information The terminal upgrade is successful.

In step S307, the detection end receives the upgrade result information and determines the upgrade result. If the upgrade is successful, the firmware upgrade process ends, and if the upgrade fails, the process proceeds to step S308.

Step S308, determining second upgrade data according to the upgrade result information and the first upgrade data, and sending the second upgrade data and a second upgrade instruction to the vehicle-mounted system, so that the vehicle-mounted system can be upgraded again.
