To restrain continuous driving of a pump operating motor in a braking-controlled state of a vehicle.SOLUTION: A braking control device comprises a control unit. The control unit determines whether or not a vehicle in an all-wheel pressure non-increase state, in which brake fluid pressures in all wheel cylinders are in a state of either being maintained or decreased in a braking-controlled state in which braking force of the wheels is controlled in accordance with a traveling state of the vehicle. When the all-wheel pressure non-increase state is determined, the control unit executes motor pumping-out restraining control which stops a pump operating motor and places a first pressure regulator valve in a valve open state, and further sets a pressure generated by pressurization means at a pressure smaller than a prescribed pressure generated in a reservoir.SELECTED DRAWING: Figure 4 【課題】車両の制動制御状態におけるポンプ作動用のモータの連続駆動を抑制する。【解決手段】制動制御装置は、車両の走行状態に応じて各車輪の制動力を制御する制動制御状態において、すべてのホイールシリンダのブレーキ液圧が保持または減圧のいずれかの状態である全輪非増圧状態か否かを判定し、全輪非増圧状態と判定した場合、ポンプ作動用のモータを停止するとともに、第１の調圧弁を閉弁状態とし、さらに、加圧手段の発生する圧力をリザーバ内で発生する所定圧力より小さい圧力とするモータ汲み出し抑制制御を実行する制御部を備える。【選択図】図４
