PROBLEM TO BE SOLVED: To provide a vehicular brake device capable of suppressing noise to reduce a power consumption while suppressing the brake fluid from moving around.SOLUTION: A vehicular brake device according to the present invention comprises: a pump 57 which discharges a brake fluid to an upstream part 59 connected to two wheel cylinders 14, 15; a first solenoid valve 51 which adjusts differential pressure between a master pressure and an upstream pressure as a pressure of the upstream part 59; a second solenoid valve 52 which adjusts a pressure of one wheel cylinder 14; a third solenoid valve 53 which adjusts a pressure of the other wheel cylinder 15; and a control part 6 which controls the pressures of the two wheel cylinders 14, 15. The control part 6 sets a discharge amount of the pump 57 based on an amount of brake fluid needed to raise the pressure of a low pressure-side wheel cylinder between the two wheel cylinders 14, 15 up to the same pressure as a target value of the high pressure side.SELECTED DRAWING: Figure 3

    【課題】回り込みを抑制しつつ、騒音を抑制し消費電力を低減させることができる車両用制動装置を提供する。【解決手段】本発明は、2つのホイールシリンダ14、15に接続された上流部59にブレーキ液を吐出するポンプ57と、マスタ圧と上流部59の圧力である上流圧との差圧を調整する第1電磁弁51と、一方のホイールシリンダ14の圧力を調整する第2電磁弁52と、他方のホイールシリンダ15の圧力を調整する第3電磁弁53と、2つのホイールシリンダ14、15の圧力を制御する制御部6と、を備え、制御部6は、2つのホイールシリンダ14、15のうち低圧側のホイールシリンダの圧力を高圧側のホイールシリンダの圧力の目標値と同じ圧力にまで増圧するのに必要なブレーキ液の液量である必要液量に基づいて、ポンプ57の吐出量を設定する。【選択図】図3
