| 摘要 |
A brake hydraulic pressure control apparatus includes a reservoir, a brake hydraulic pressure supply device, a hydraulic pump, a plurality of wheel cylinders, a cut valve, a plurality of pressure-increasing solenoid valves, a plurality of pressure-decreasing solenoid valves, a discharge passage including a plurality of relief passages and a circulating passage, a controlling device bringing a brake hydraulic pressure to be applied to the wheel cylinders from the hydraulic pump by disconnecting the brake hydraulic pressure supply device from the wheel cylinders by the cut valve while the pressure-increasing solenoid valves are in an open state, and bringing the brake fluid within the wheel cylinders to be circulated to the reservoir via the discharge passage by operating the pressure-decreasing solenoid valves, and a pulsation transmission decreasing device provided at the discharge passage and decreasing a transmission of a pressure pulsation generated by at least one of the pressure-decreasing solenoid valves.
