To suppress a decrease in brake fluid pressure against a driver's intention during vehicle stop time holding control.SOLUTION: A vehicle brake fluid pressure control device is a vehicle brake fluid pressure control device capable of executing vehicle stop time holding control (time t2 to t3) for holding brake fluid pressure when it is determined that a vehicle has stopped. The vehicle brake fluid pressure control device releases the vehicle stop time holding control even if there is no operation of an operation member for operating the vehicle when a first condition is satisfied (time t3), the first condition including a fact that a vehicle body speed Vb at the time of brake input is equal to or greater than a speed specified value Vth, a fact that an absolute value (maximum value Awmax) of a wheel deceleration has exceeded a deceleration specified value Ath after the brake input, and a fact that a lateral behavior amount (yaw rate Y) of the vehicle is equal to or greater than the specified value Yth during the vehicle stop time holding control.SELECTED DRAWING: Figure 7

    【課題】停車時保持制御中においてドライバーの意図に反するブレーキ液圧の低下を抑えることを目的とする。【解決手段】車両用ブレーキ液圧制御装置は、車両が停止したと判定した場合にブレーキ液圧を保持する停車時保持制御(時刻t2~t3)を実行可能な車両用ブレーキ液圧制御装置であって、ブレーキ入力時の車体速度Vbが速度規定値Vth以上であったこと、ブレーキ入力後に車輪減速度の絶対値(最大値Awmax)が減速度規定値Ath以上になったこと、および、停車時保持制御中において車両の横方向の挙動量(ヨーレートY)が規定値Yth以上であることを含む第1条件が満たされた場合には(時刻t3)、車両を操作するための操作部材の操作がなくても、停車時保持制御を解除する。【選択図】図7
