Abstract:
1. Braking control system for automotive vehicles comprising a braking control member ( 1 ), a brake booster ( 4 ) which comprises a vacuum chamber ( 40 ) and a working chamber ( 41 ) separated by a servomotor piston ( 42 ), said brake booster ( 4 ) being operable to provide increased braking control according to the difference in pressure existing between said two chambers, a brake master cylinder ( 5 ) receiving increased braking commands from the brake booster ( 4 ) and producing a braking pressure in the hydraulic braking circuit ( 6 ) of the vehicle, the system further comprising a simulator ( 3 ) coupled one of pneumatically and hydraulically to the piston ( 42 ) of the brake booster ( 4 ), said simulator ( 3 ) receiving at least one braking command from the braking control member ( 1 ) and being operable to one of establish and monitor, in return, a difference in pressure between the vacuum chamber ( 40 ) and the working chamber ( 41 ) of the brake booster so as to control the displacement of the piston ( 42 ) characterized in that said simulator ( 3 ) comprises a hydraulically controlled pneumatic three-way valve operable to: the event of a braking command initiated by the braking control member ( when the pressure in the hydraulic braking circuit ( an axially mobile probe ( an axially mobile check valve ( an axially mobile check valve seat ( the mobile probe (
