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