PROBLEM TO BE SOLVED: To provide a vehicle stop maintaining device capable of executing both a vehicle stop state maintaining function and a fuel efficiency improvement function.SOLUTION: A vehicle stop maintaining device comprises: an idling stop device 2; a DSC device 4; an ECU 6 which activates the idling stop device 2 to stop an engine 7 when brake fluid pressure Pb in accordance with pressing operation of a brake pedal 10 exceeds a threshold t1 and executes automatic hold control by activating the DSC device 4 when the brake fluid pressure Pb exceeds the threshold t3; and an automatic hold switch 60 which can switch between a permission mode to permit the automatic hold control through the DSC device 4 and a prohibition mode to prohibit the same. The ECU 6 is adapted to change the threshold t1 to the threshold t2 lower than the same when the permission mode to permit the automatic hold control through the DSC device 4 is selected.SELECTED DRAWING: Figure 2

    【課題】車両の停止状態維持機能と燃費改善機能とを両立可能な車両の停止維持装置を提供する。【解決手段】アイドルストップ装置2と、DSC装置4と、ブレーキペダル10の踏込操作に応じたブレーキ液圧Pbが閾値t1を超えたときにアイドルストップ装置2を作動させてエンジン7を停止すると共にブレーキ液圧Pbが閾値t3を超えたときにDSC装置4を作動させてホートホールド制御を実行するECU6と、DSC装置4を介したオートホールド制御を許可する許可モードと許可しない禁止モードとを切り替え可能なオートホールドスイッチ60とを有し、ECU6は、DSC装置4を介したオートホールド制御が許可モードのとき、閾値t1に代えて閾値t1よりも低い閾値t2を設定するように構成される。【選択図】 図2
