and when the first electric quantity value is higher than a first threshold value or the vehicle is in an ignition state, detecting that the vehicle-mounted terminal enters a full-speed mode, wherein the full-speed mode is a mode that all modules of the vehicle-mounted terminal are in a normal working state. It can be understood that the vehicle-mounted terminal can be powered by power when the vehicle is in the ignition state, and therefore the vehicle-mounted terminal does not need to be controlled to enter the sleep mode.
