초록 ▼

A braking system having a pressure modulator which, during normal braking operation, delivers a fluid pressure which is a predetermined multiple of a fluid pressure generated by the master cylinder to a wheel cylinder. The pressure modulator has a solenoid actuator which is energized during braking force proportioning and anti-skid operations to reduce the delivery pressure. In a preferred embodiment, the pressure modulator further includes another solenoid actuator for increasing the delivery pressure during braking force proportioning operation and for delivering fluid pressure during traction control operation.

대표청구항 ▼

A braking system for providing an anti-skid function and a braking force proportioning function for a wheeled vehicle, wherein, during anti-skid operation, a fluid pressure communicated to a wheel cylinder of a brake is reduced upon occurrence of a potential wheel skid condition to eliminate the potential wheel skid condition, whereupon said fluid pressure is increased to retard the rotation of the wheel, and wherein, during a braking force proportioning operation, the fluid pressure communicated to the wheel cylinder is controlled in response to a varying load condition imposed upon the wheel or to a varying road surface condition to which the wheel is subjected, said braking system comprising: the brake, including the wheel cylinder, responsive to a fluid pressure for retarding the rotation of the wheel; a master cylinder actuated by a vehicle operator for generating a controlled fluid pressure; a source of a predetermined fluid pressure substantially higher than said controlled fluid pressure; a reservoir for a brake fluid; and, a pressure modulator in fluid communication with said wheel cylinder, said master cylinder, said source and said reservoir for controlling fluid pressure communicated to said wheel cylinder; said modulator comprising valve means responsive to said controlled fluid pressure for controlling communication between said source and said wheel cylinder and between said wheel cylinder and said reservoir so that a modulated fluid pressure which is a multiple of said controlled fluid pressure is communicated to said wheel cylinder during normal braking operation; said modulator also comprising electronically controllable first biasing means responsive to electric control signals for biasing said valve means in such a manner that said modulated fluid pressure communicated to the wheel cylinder is reduced during anti-skid and braking force proportioning operations of the braking system.
