In the vehicle provided with a device to automatically stop/start an engine, when a brake pedal depression amount decreases in a state where the engine has temporarily stopped, the engine is restarted to alert the driver. The brake pedal depression amount in this case is set to a level such that a braking force exceeds a creep force. This restarting of the engine encourages the driver to step on the brake pedal, and reinforces braking force. As a result, when the engine is restarted after temporarily stopping due to a command from a control unit regardless of the driver's intention, such as when the battery is being charged, there is less release of the brake pedal. In this way, moving-off of the vehicle regardless of the driver's intention can be prevented.When automatic stop conditions are satisfied, the engine 1 stops, and when start conditions are satisfied, an induction motor 2 for starting the vehicle is started to restart the engine 1. If the brake pedal depression amount decreases even slightly during temporary stop of the engine, when the brake is released, the engine is restarted. Due to the generation of a creep force, the driver is requested to step on the brake pedal again. As a result, when the engine restarts, for example in order to charge the battery, after temporarily stopping due to a command from the controller unrelated to the driver's intention, the vehicle can be prevented from moving off.
