PROBLEM TO BE SOLVED: To provide a vehicular brake fluid pressure controller for accurately estimating a brake fluid pressure in a fluid passage on an upstream side of a control valve unit, without using a pressure sensor.SOLUTION: The higher a brake fluid pressure (upstream side brake fluid pressure), namely a master cylinder pressure Pmc, in a fluid passage 104 on an upstream side which is a discharge side of a brake fluid of a pump 70 is, the greater load is applied to a motor 72 for driving the pump 70 at an operation start of the pump 70, and accordingly a rotation start current Imstart of the motor 72 becomes greater. Therefore, the rotation start current Imstart is correctly detected by increasing a motor current Im from a zero value with a gentle gradient, and on the basis of the detected rotation start current Imstart, the upstream side brake fluid pressure (the master cylinder pressure Pmc) can be correctly estimated.SELECTED DRAWING: Figure 1

    【課題】圧力センサを用いないで、制御弁ユニットの上流側液路のブレーキ液圧を精度よく推定する車両用ブレーキ液圧制御装置を提供する。【解決手段】ポンプ70のブレーキ液の吐出側である上流側液路104のブレーキ液圧(上流側ブレーキ液圧)、すなわちマスタシリンダ圧Pmcが高い程、ポンプ70の作動開始時にポンプ70を駆動するモータ72に大きな負荷がかかり、モータ72の回転開始電流Imstartが大きくなる。そこで、モータ電流Imを0値から緩勾配で増加させて回転開始電流Imstartを正確に検出し、検出した回転開始電流Imstartに基づき上流側ブレーキ液圧(マスタシリンダ圧Pmc)を精度よく推定できる。【選択図】図1
