摘要： A hydraulic pressure control device in a vehicle anti-skid braking system includes a brake master cylinder, a wheel brake actuating cylinder for braking a wheel in response to a fluid pressure from the brake master cylinder, and a directional control valve actuatable in response to a control signal from a control unit which detects a wheel condition such as wheel skidding, for returning a braking fluid from the wheel brake actuating cylinder via a return passage to a fluid pressure supply passage connected to the master cylinder. The return passage has an accumulator for storing part of the fluid from the wheel brake actuating cylinder in an anti-skid control mode. A fluid overflow from the accumulator is delivered via a restriction in the supply passage to the master cylinder to act on the brake pedal as a pedal reaction.

摘要： In an anti-skid braking apparatus for vehicles of the type having a fluid-pressure control valve arranged between a master cylinder and a wheel cylinder for controlling the brake fluid pressure within the wheel cylinder, when it is detected that the vehicle stops, the fluid-pressure control valve is controlled so as to assume a pressure-maintaining mode and a pressure-increasing mode alternately for a predetermined period of time as long as the brake pedal is continuously depressed. As a result, the pressure of the fluid increases stepwise preventing the occurrence of uncomfortable kickback at the brake pedal.

摘要： An automotive anti-lock brake control system includes first and second directional control valves selectively shiftable between a first position in which a master cylinder communicates with first and second wheel cylinders associated with front and rear wheels, respectively, and a second position in which the first and second wheel cylinders communicate with a reservoir. A proportional valve is disposed between the master cylinder and the second directional control valve for producing a fluid pressure difference between the first and second wheel cylinders. The brake fluid stored in the reservoir is pumped by a fluid pump back to a pipe portion between the master cylinder and the proportional valve.
