Abstract: A hydraulic pressure control unit capable of reducing pulsation generated during driving of pumps and capable of suppressing enlargement of the hydraulic pressure control unit is provided. The hydraulic pressure control unit (50) includes the plural pumps (60) used to increase a hydraulic pressure of brake fluid in each hydraulic circuit. The hydraulic pressure control unit (50) also includes a discharge channel (140) provided on discharge sides of the plural pumps (60). The discharge channel (140) includes: a merging channel (141) having a downstream end; and plural distributary channels (142) respectively communicating with the discharge sides of the pumps (60).

Abstract: A hydraulic pressure control unit and a vehicle brake system including the hydraulic pressure control unit are obtained. The hydraulic pressure control unit can downsize the brake system in comparison with a conventional brake system. A hydraulic pressure control unit (50) is a hydraulic pressure control unit 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 that flows into the accumulator (33) from a suction side of the pump (34).
