And as shown in table 1, table 1 is as follows:

TABLE 1

As shown in table 1, when only the client 2 and the vehicle-mounted terminal 1 report that the vehicle status is "available vehicle", the system classifies the vehicle as an "available vehicle"; as long as one of the two is reported as the vehicle to be maintained, the system necessarily classifies the vehicle into the vehicle to be maintained; other situations are classified as "vehicles to be serviced".

When a certain vehicle state is "vehicle to be repaired" or "vehicle to be maintained", the customer terminal 2 of the maintenance person will receive the repair/maintenance task and be authorized to use the vehicle. After the maintenance personnel finish the vehicle maintenance task, the vehicle state of the vehicle can be applied and updated to be the available vehicle, and the cloud 3 system withdraws the vehicle using authority of the maintenance personnel and updates the vehicle state to be the available vehicle.
