Optionally, the preset time difference range is a time range set according to a preset duration. The time difference may be within a predetermined time difference range, and may not yet reach the predetermined time difference range. And if the time difference is within the preset time difference range, indicating that the preset time length is elapsed after the vehicle positioning module determines the positioning time through the satellite. The exact current time should be the positioning time plus a preset duration. And if the time difference is not in the preset time difference range, indicating that the time length passing after the vehicle positioning module determines the positioning time through the satellite does not reach the preset time length.

The vehicle control apparatus then detects whether the recalculated time difference is greater than 995 milliseconds and less than 1005 milliseconds. If the recalculated time difference is greater than 995 milliseconds and less than 1005 milliseconds, the vehicle control device adds 1 second to the positioning time to obtain a current time correction time corresponding to the vehicle dome lamp. If the recalculated time difference is not within the preset time difference range, the vehicle control device continues to wait for 1 millisecond and recalculate the time difference between the current system time and the acquisition time of the current positioning information until the time difference is greater than 995 milliseconds and less than 1005 milliseconds.
