PROBLEM TO BE SOLVED: To improve durability of a device at the time of shifting from a pressure increase mode to a pressure decrease mode, relating to a vehicular brake.SOLUTION: A vehicular brake device includes a decision part which decides execution of state shifting from a pressure increase mode in which an electric pump is operated in a closed state of a differential pressure valve and an open state of a holding valve to a pressure decrease mode in which the electric pump is operated in a closed state of the holding valve and the open state of the pressure decreasing valve, and a control part which, following decision of execution of the state shifting by the decision part, controls any one or more of the differential pressure valve, the holding valve, the pressure decreasing valve, and the electric pump, to reduce an amount of brake fluid which is resident in a path between the differential pressure valve and the holding valve.SELECTED DRAWING: Figure 6
【課題】 車両用制動装置において、増圧モードから減圧モードに推移する場合、装置の耐久性を向上する。【解決手段】差圧弁が閉状態かつ保持弁が開状態で電動ポンプを作動させる増圧モードから、前記保持弁が閉状態かつ減圧弁が開状態で前記電動ポンプを作動させる減圧モードへの状態遷移の実行を決定する決定部と、前記決定部により、前記状態遷移の実行が決定されたことに伴って、前記差圧弁、前記保持弁、前記減圧弁、前記電動ポンプのいずれか一つ以上制御を行い、前記差圧弁と前記保持弁との間の経路に滞留するブレーキ液の量を低減する制御部と、を備えることを特徴とする。【選択図】 図6
