Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress electric power consumption of a motor in a vehicle that performs idle stop control during deceleration by elaborately performing engine drive control by using the motor during the idle stop control.SOLUTION: A vehicle includes: an engine; a mechanical oil pump driven by the revolution of the engine; a step automatic transmission having a plurality of friction fastening elements that can be fastened by hydraulic pressure supplied from the mechanical oil pump; and a motor that can rotationally drive the engine. During the deceleration of the vehicle, when combustion of the engine is stopped and the engine is in a predetermined revolution decline state, the engine is rotationally driven by the motor so that hydraulic pressure in accordance with a gear shift stage corresponding to the driving state of the vehicle is discharged from the mechanical oil pump.SELECTED DRAWING: Figure 6 【課題】減速時アイドルストップ制御を行う車両において、この制御中におけるモータによるエンジン駆動制御を緻密に行うことにより、モータの電力消費を抑制する。【解決手段】エンジンと、エンジンの回転によって駆動される機械式オイルポンプと、機械式オイルポンプから供給される油圧によって締結可能な複数の摩擦締結要素を有する有段式の自動変速機と、エンジンを回転駆動可能なモータとを備えた車両において、車両の減速中において、エンジンの燃焼が停止され且つ該エンジンが所定の回転低下状態であるとき、車両の運転状態に対応する変速段に応じた油圧が機械式オイルポンプから吐出されるように、モータによってエンジンを回転駆動させる。【選択図】図６
