PROBLEM TO BE SOLVED: To provide a vehicular brake fluid pressure controller which can suppress unnecessary extension of a drive time of a motor and discomfort of a crew member caused by operation sound of the motor during ABS control.SOLUTION: A vehicular brake fluid pressure controller 1 comprises: an inlet valve 13 interposed at a fluid pressure passage from a fluid pressure source to a wheel brake; an outlet valve 14 interposed at a fluid pressure passage from the wheel brake to a reservoir; a pump 17 interposed at a fluid pressure passage from the reservoir to the fluid pressure source; an electric motor 21 driving the pump 17; and a control unit 100 which performs a control in which the brake fluid reserved in the reservoir is returned to the fluid pressure source side by ABS control and driving of the electric motor 21. The control unit 100 starts driving of the electric motor 21 when starting a pressure reduction control and sets target discharge time based on a road surface friction coefficient. The control unit stops the electric motor 21 even during ABS control in a case that the target discharge time has passed since completion of the pressure reduction control.SELECTED DRAWING: Figure 3

    【課題】ABS制御中における、モータの駆動時間が不要に長くなるのを抑えたり、モータの作動音により乗員が不快に感じるのを抑えたりすることができる車両用ブレーキ液圧制御装置を提供する。【解決手段】車両用ブレーキ液圧制御装置1は、液圧源から車輪ブレーキへの液圧路に介装された入口弁13と、車輪ブレーキからリザーバへの液圧路に介装された出口弁14と、リザーバから液圧源への液圧路に介装されたポンプ17と、ポンプ17を駆動する電動モータ21と、ABS制御とリザーバ内に溜めたブレーキ液を電動モータ21の駆動によって液圧源側へ戻す制御を実行する制御部100とを備える。制御部100は、減圧制御を開始する際に電動モータ21の駆動を開始するとともに、路面摩擦係数に基づいて目標吐出時間を設定し、減圧制御の終了から目標吐出時間が経過した場合には、ABS制御中であっても電動モータ21を停止する。【選択図】図3
