PROBLEM TO BE SOLVED: To provide a stop maintaining device of a vehicle capable of achieving securing of execution reliability of automatic hold and suppression of generation of allophone.SOLUTION: A stop maintaining device of a vehicle comprises: an idle stop device 2; a foot brake device 3 which can brake wheels 11 through a liquid pressure brake mechanism 20; a DSC device 4; and an ECU 6 which holds a brake liquid pressure Pb in accordance with a stepping operation of the brake pedal 10 when a stop state of a vehicle V is detected and maintains a stop state. The ECU 6 has a first threshold t1 in accordance with a brake liquid pressure ta higher than an upper limit of a stick slip generation possible area on the liquid pressure brake mechanism 20, and when the vehicle V is in the stop state, and the brake liquid pressure Pb in accordance with the stepping operation of the brake pedal 10 is less than the first threshold t1, executes a first boosting correction for boosting the brake liquid pressure Pb in accordance with the stepping operation of the brake pedal 10 to equal to or more than the first threshold t1 by actuating the DSC device 4.SELECTED DRAWING: Figure 2
【課題】オートホールドの実行信頼性確保と異音の発生抑制を両立させることができる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、液圧ブレーキ機構20を介して車輪11を制動可能なフットブレーキ装置3と、DSC装置4と、車両Vの停止状態が検出されたときにブレーキペダル10の踏込操作に応じたブレーキ液圧Pbを保持して停止状態を維持するECU6とを備え、ECU6は、液圧ブレーキ機構20にスティックスリップ発生可能領域の上限よりも高いブレーキ液圧taに応じた第1閾値t1を有すると共に、車両Vが停止状態で且つブレーキペダル10の踏込操作に応じたブレーキ液圧Pbが第1閾値t1未満のとき、DSC装置4を作動させてブレーキペダル10の踏込操作に応じたブレーキ液圧Pbを第1閾値t1以上に増圧する第1増圧補正を実行する。【選択図】 図2
