In a vehicle which has an automatic stop/restart device of the engine 1, the engine 1 is started rapidly only in cases where a quick start of the engine 1 is required such as when the vehicle is stationary on a rising slope, or cuts across the opposite lane for a left turn. For this purpose, excitation of an motor 2 is performed before startup of the motor 2 for restarting the engine 1 quickly. When automatic stop conditions are satisfied, the engine 1 stops, and when restart conditions are satisfied, the motor 2 is started to restart the engine 1. When the vehicle is on a rising slope and it is required to start the vehicle quickly, the motor 2 is energized first before the motor 2 is started. Also, when it is determined that the vehicle must start rapidly such as when the vehicle is trying to cut across the opposite lane for a left turn, the motor 2 is excited before it starts. In this way, when it is desired to start the vehicle quickly, a rapid restart of the engine 1 and therefore rapid start of the vehicle is possible.
