A hydraulic pressure control unit (50) and a vehicle brake system (1) including the hydraulic pressure control unit (50) are obtained. The hydraulic pressure control unit (50) can downsize the brake system (1) in comparison with a conventional brake system, esp. an optimized hydraulic boost (OHB) brake system with a downsized or eliminated booster. The hydraulic pressure control unit (50) according to the invention is a hydraulic pressure control unit (50) for a brake system (1) of a vehicle (100). The hydraulic pressure control unit (50) includes a pump (34) and an accumulator (33) in a secondary channel (14), the pump (34) increasing a hydraulic pressure of brake fluid and the accumulator (33) storing the brake fluid. The secondary channel (14) is configured to allow a flow of the brake fluid flowing into the accumulator (33) from a suction side of the pump (34) and/or from a second switching valve (HSV; 36) located in a supply channel between the master cylinder (11) and the suction side of the pump (34).

    L'invention concerne : une unité de commande hydraulique avec laquelle il est possible de fabriquer des systèmes de freinage plus compacts que dans la technique antérieure ; un système de freinage pour un véhicule équipé de ladite unité de commande hydraulique. Une unité de commande hydraulique (50) est une unité de commande hydraulique pour un système de freinage (1) pour un véhicule (100) ayant une pompe (34) permettant une amplification de la pression hydraulique de fluide de frein, et un accumulateur (33) qui accumule un fluide de frein, sur un chemin auxiliaire (14), le chemin auxiliaire (14) permettant l'écoulement du fluide de frein du côté d'admission de la pompe (34) vers l'accumulateur (33).

    ブレーキシステムを従来よりも小型化することができる液圧制御ユニット、及び該液圧 制御ユニットを備えた車両用のブレーキシステムを得る。 液圧制御ユニット50は、ブレーキ液の液圧を上昇させるポンプ34、及び、ブレーキ 液を貯留するアキュムレータ33を副流路14に有する車両100用のブレーキシステム 1の液圧制御ユニットであって、副流路14がポンプ34の吸込側からアキュムレータ3 3へ流入するブレーキ液の流れを許容する構成となっている。
