摘要:
Described is a braking-pressure control system, especially for a road vehicle, having a pneumatic brake booster (14), having a main cylinder (16) in which a main-cylinder pressure (PHZ) can be generated by a pneumatic brake booster (14), and having a hydraulic modulator (17) which is connected between the main cylinder (16) and at least one wheel-brake cylinder (10-13) of at least one wheel; the hydraulic modulator (17) including a configuration of switchable valves (ASV, USV, EV, AV), as well as one pump (25, 25′); and a wheel-brake cylinder pressure (PRZ) being able to be generated in the at least one wheel-brake cylinder (10-13), using the hydraulic modulator; the wheel-brake cylinder pressure being higher than the main-cylinder. pressure (PHZ). The braking-pressure control system is characterized in that the pneumatic brake booster (14) is designed in a manner allowing it to already reach its saturation point (A0, A1) at a main-cylinder pressure (PHZ) of less than 50 bar.
