PROBLEM TO BE SOLVED: To improve fuel economy by reducing an energy loss of an oil pump motor and a high pressure accumulator in deceleration regeneration time.SOLUTION: A regenerative control method for a vehicle is provided that includes: a determination step of determining whether or not to satisfy a first condition in which an oil pump motor 13 is present in an oil pump motor number of revolutions area being undesirable in deceleration regeneration efficiency by the oil pump motor 13 or a second condition in which a high pressure accumulator 14 is present in a temperature area of the high pressure accumulator 14 causing an energy loss in deceleration regeneration time; and a sharing step of sharing deceleration regeneration on the oil pump motor 13 side and the engine 1 side by connecting both of an oil pump motor 13 side clutch 12 and an engine 1 side clutch 2 when determined as satisfying the first condition and the second condition by the determination step.SELECTED DRAWING: Figure 1
【課題】減速回生時に、オイルポンプモータや高圧蓄圧器のエネルギーロスを低減させて燃費を向上させる。【解決手段】減速回生時に、オイルポンプモータ13による減速回生効率の悪いオイルポンプモータ回転数領域にあるという第1条件又はエネルギーロスが発生する高圧蓄圧器14の温度領域にあるという第2条件を満たすか否かを判定する判定工程と、判定工程により第1条件又は第2条件を満たすと判定されたときに、オイルポンプモータ13側のクラッチ12及びエンジン1側のクラッチ2の両方を繋ぎ、減速回生をオイルポンプモータ13側及びエンジン1側に分担させる分担工程とを含む。【選択図】図1
