Abstract
A hydraulic brake system wherein a portion of a volume of a first fluid supplied to a steering system by a pump is selectively diverted to an actuator assembly for a master cylinder to develop an force for actuating a master cylinder to pressurize fluid which is supplied to wheel brakes. An electronic control unit (ECU) for the brake system receives a first input signal indicative of the flow of fluid from the pump in the steering system, a second input signal indicative of the input force applied by the operator and a third input signal indicative of the speed of the wheels of the vehicle for developing a pulse modulated operational signal. The electronic control develops an operational signal which is supplied as the pulse modulated operational signal to a magnetic responsive valve. The pulse modulated operational signal creates a variable orifice in the magnetic responsive valve to restrict the flow of the first fluid to the steering gear and increases the fluid pressure of the first fluid. This increase in the fluid pressure of the first fluid is develops an operational force for actuating the master cylinder to effect a brake application. The electronic control unit supplies t…
