Patent ID: 8380414

Claim:
System for simulating brake feel for a vehicle braking installation comprising a hydraulic braking system ( 7 , 8 ) operated by muscle power of the driver, and an auxiliary braking system, characterized in that the system comprises a first chamber ( 20 ) containing a force transmitting fluid ( 21 ) and in which there slides a hydraulic piston ( 22 ) driven by a manual braking operating member ( 1 ) and a piston ( 23 ) for operating the hydraulic braking system ( 7 , 8 ), said first chamber ( 20 ) communicating on command with a second, secondary simulation chamber ( 4 ) via a simulation valve ( 3 ), a degree of opening of which allows a force to be simulated at a brake pedal, and in that the system comprises a blocking valve ( 80 ) blocking operation of said hydraulic braking system ( 7 , 8 ), this blocking valve being commanded into a blocking state by a central control unit ( 5 ) when the simulation system is actuated.
