Abstract: A hydraulic adaptive braking system is disclosed which uses a single fluid to both actuate the brakes of the vehicle and to provide a power assist to the vehicle operator when the brakes are applied. The system includes a brake booster which utilizes pressurized fluid from the vehicle''s power steering pump to develop braking pressure which is communicated to the brakes of the vehicle. Adaptive braking valve means are located in both the front and the rear brake lines and include electrically operated valve means which control fluid communication between the booster, the brakes of the vehicle and a fluid reservoir. When an incipient skid condition is sensed, the electrically operated valve means terminate fluid communication between the booster and the vehicle''s brakes, and then initiates communication between the vehicle''s brakes and the aforementioned reservoir to permit braking pressure at the brakes of the vehicle to decay. When the incipient skid condition terminates, the electrically operated valve means again communicates braking pressure to the vehicle''s brakes.

Abstract: A hydraulic brake booster is disclosed which includes a housing defining a bore therewithin, a boost piston which is slidably mounted in the bore and cooperates with one end of the latter to define a pressure chamber between the piston and the end of the bore, and a valve which controls fluid communication between a pressure source and the pressure chamber. A valve actuation rod is controlled by the vehicle operator and includes an inner member for operating the valve and an outer member which is responsive to the fluid pressure level in the chamber to transmit reaction forces to the vehicle operator, thereby providing brake ''''feel''''. The outer member is effective to transmit reaction forces only when the pressure level in the pressure chamber exceeds a predetermined value. Therefore, when the vehicle operator initially applies the brakes of the vehicle, only a very small reaction force will be transmitted through the valve operating rod. However, when the pressure level in the pressure chamber exceeds the predetermined value, a substantially greater portion of the force generated by the fluid pressure in the pressure chamber is transmitted to the vehicle operator.

Abstract: A hydraulic brake booster is disclosed which includes a housing in fluid communication with a fluid pressure source and with a reservoir. A piston is slidably mounted in the housing, and valve means are provided to selectively admit fluid from the fluid pressure source to one side of the piston for shifting the latter within the housing to apply the brakes of the vehicle. Operatoractuated means are provided for controlling the valve means. Movement of the piston within the housing progressively pressurizes a deformable rubber member disposed adjacent one end of the piston. A plunger is provided that senses a proportional amount of the pressurization of the deformable member and transmits a corresponding force to the operator-actuated means, opposing movement of the latter, to thereby provide braking ''''feel'''' to the vehicle operator.
