PROBLEM TO BE SOLVED: To make a timing of estimating a road surface μ earlier.SOLUTION: A vehicular brake fluid pressure control device includes a wheel deceleration degree calculation means 110 for calculating a wheel deceleration degree of each wheel, a wheel cylinder pressure acquiring means (wheel cylinder pressure estimating means 120) for acquiring a wheel cylinder pressure of a front wheel, and a high μ path determination means 130 which determines whether or not a road surface is a high μ path based on the front wheel cylinder pressure acquired by the wheel cylinder pressure acquiring means and the wheel deceleration degree of each wheel that is calculated by the wheel deceleration degree calculation means.SELECTED DRAWING: Figure 3

    【課題】路面μを推定するタイミングを早くす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、各車輪の車輪減速度を算出する車輪減速度算出手段110と、前輪のホイールシリンダ圧を取得するホイールシリンダ圧取得手段(ホイールシリンダ圧推定手段120)と、ホイールシリンダ圧取得手段によって取得した前輪のホイールシリンダ圧と、車輪減速度算出手段によって算出された各車輪の車輪減速度とに基づいて、路面が高μ路であるか否かを判断する高μ路判定手段130と、を備える。【選択図】図3
