[0036] The engine status and the target controller status both meet the flashing requirements, including: the engine is not started, and the target controller is awake or working.

[0037] The vehicle terminal is also connected to the display module; the display module is connected to the steering wheel; the display module is used to display the target program flashing confirmation information and the target program flashing status. When the target vehicle is in the working state, the vehicle terminal receives the information sent to remind the driver to confirm the flashing, and the driver confirms the flashing through the steering wheel.

[0038] The vehicle terminal is also connected to the client; the vehicle terminal will provide feedback to the client when the target program flashing instruction does not meet the integrity requirements; and will provide feedback to the client when either the engine status or the target controller status does not meet the flashing requirements. The vehicle terminal is also used to remind the driver that the target program flashing is complete and provide feedback to the client at the same time after the target program flashing is completed.

[0039] The vehicle-mounted terminal is also used to temporarily save the received target program.

[0040] In this application, the vehicle-mounted terminal is T-BOX; the full name of T-BOX is Telematic BOX, which refers to the vehicle-mounted terminal of the Internet of Vehicles system, which is used to collect various types of data. T-BOX is a wireless gateway that provides a remote information interface for the vehicle.

[0041] The network communication server is responsible for receiving the program and sending it to T-BOX. T-BOX is responsible for receiving the program file and temporarily storing it, checking the vehicle status and the target controller status, and reminding the client that the program can be flashed when the flashing conditions are met. The instrument panel displays the program flashing confirmation information and the program flashing status. When the vehicle is in working state, T-BOX will send a reminder to the instrument panel, and the driver will confirm the flashing. If the flashing conditions are not met, specific information will be fed back to the client. After the program is flashed, the driver will be reminded that the program is flashed and the client will be fed back.
