Patent ID: 8523294

Claim:
A system for use in a vehicle with a brake pedal and a brake circuit, comprising: a master cylinder assembly configured to pressurize fluid therein in response to movement of said brake pedal; a sensor assembly configured to generate a pedal position signal indicative of position of said brake pedal; an electronic control unit configured to (i) generate a brake request signal in response to generation of said pedal position signal, and (ii) generate a selector control signal; a selector valve assembly operable in a first mode and a second mode, said selector valve assembly being moved from said first mode to said second mode in response to generation of said selector control signal; a pedal feel simulator (i) in fluid communication with said master cylinder through said selector valve assembly when said selector valve assembly is positioned in said first mode, and (ii) isolated from fluid communication with said master cylinder by said selector valve assembly when said selector valve assembly is positioned in said second mode; a booster actuator configured to generate force in response to generation of said brake request signal; and a booster assembly configured to pressurize fluid therein in response to generation of force by said booster actuator, wherein said master cylinder assembly is (i) isolated from fluid communication with said brake circuit by said selector valve assembly when said selector valve assembly is positioned in said first mode, and (ii) in fluid communication with said brake circuit through said selector valve assembly and said booster assembly when said selector valve assembly is positioned in said second mode, wherein said booster assembly is in fluid communication with said brake circuit when said selector valve assembly is positioned in said first mode and in said second mode, and wherein said selector valve assembly includes a solenoid which is configured to move said selector valve assembly from said first mode to said second mode in response to generation of said selector control signal.
