To provide a brake fluid pressure control device which can improve an operation feeling of a brake operator at interlocked brake control while suppressing a manufacturing cost.SOLUTION: A brake fluid pressure control device U has brake systems K1, K2 at a front wheel side and a rear wheel side, and a control device 7. The front-wheel side brake system K1 comprises a pressure regulation valve 1 which can regulate valve-opening pressure for making a brake fluid flow to an output fluid pressure path A side from a wheel fluid pressure path B side. The control device 7 sets the valve-opening pressure of the pressure regulation valve 1 to target pressure at interlocked brake control by which a brake force is generated at a front-wheel side wheel brake in conjunction with the rear-wheel side brake system K2. Also, when a front-wheel side brake lever L1 is operated at the interlocked brake control, the control device 7 sets the valve-opening pressure of the pressure regulation valve 1 to correction pressure which is higher than the target pressure.SELECTED DRAWING: Figure 2
【課題】製造コストを抑えつつ、連動ブレーキ制御時のブレーキ操作子の操作フィーリングを向上させることができるブレーキ液圧制御装置を提供する。【解決手段】前輪側および後輪側のブレーキ系統K1,K2と、制御装置7と、を有するブレーキ液圧制御装置Uである。前輪側のブレーキ系統K1は、車輪液圧路B側から出力液圧路A側にブレーキ液を流すための開弁圧を調整可能な調圧弁1を備えている。制御装置7は、後輪側のブレーキ系統K2に連動して前輪側の車輪ブレーキに制動力を発生させた連動ブレーキ制御時に、調圧弁1の開弁圧を目標圧力に設定する。また、制御装置7は、連動ブレーキ制御時に前輪側のブレーキレバーL1が操作されたときには、調圧弁1の開弁圧を目標圧力よりも大きい補正圧力に設定する。【選択図】図2
