That is, when the vehicle-ground communication is normal, the interactive software between the vehicle-mounted subsystem and the ground subsystem and the bottom hardware of the vehicle-mounted subsystem and the ground subsystem can be determined to be in a normal working state; when vehicle-to-ground communication is not possible, it may be determined that the underlying hardware of the interactive software between the vehicle-mounted subsystem and the ground subsystem, or both, may be malfunctioning. In the related art, the vehicle-mounted subsystem and the ground subsystem to be tested are generally tested for vehicle-ground communication by connecting an LTE (Long Term Evolution) router.
