Abstract
An oil pump driven by an engine generates a hydraulic pressure supplied to a frictional engagement element. An accumulator provided at an intermediate position of an oil path supplies the hydraulic pressure generated by the oil pump to the frictional engagement element. A controller stops the engine after a hydraulic pressure reducing condition to reduce the hydraulic pressure supplied to the frictional engagement element holds and the hydraulic pressure supplied to the frictional engagement element is reduced.
