While a vehicle is decelerating starting at a braking start time, start-off pre-shifting starts when speed falls to a predetermined speed. At a vehicle stoppage time, an idle stop permission flag is not set to on if start-off pre-shifting is incomplete, even if idle stop permission conditions have been met. The idle stop permission flag is set to on when start-off pre-shifting is completed, and an idle stop flag is set to on and the engine stopped when engine rotational speed falls below a set speed. The engine is restarted in response to braking being released, and the idle stop flag is set to off and the idle stop control ended when the engine rotational speed reaches or exceeds a set speed. The restarting of the engine causes an engine-driven oil pump to dispense oil to be used as a medium to manifest an automatic clutch command hydraulic pressure.
