Abstract:
1. A brake system for a vehicle, comprising: a brake actuating element; a first piston-cylinder unit, wherein the brake actuating element is disposed at the first piston-cylinder unit in such a way that a first piston of the first piston-cylinder unit is displaced by actuation of the brake actuating element by at least a predefined minimum actuation so that a first internal pressure in the first piston-cylinder unit is increased; at least one wheel brake cylinder hydraulically connected to the first piston-cylinder unit in such a way that a brake pressure of the at least one wheel brake cylinder is increased using the increased first internal pressure in the first piston-cylinder unit; a first brake booster; a second piston-cylinder unit, wherein the first brake booster is disposed at the second piston-cylinder unit in such a way that a second piston of the second piston-cylinder unit is displaced by the first brake booster so that a second internal pressure in the second piston-cylinder unit is increased, and wherein the at least one wheel brake cylinder is hydraulically connected to the second piston-cylinder unit in such a way that the brake pressure of the at least one wheel brake cylinder is increased using the increased second internal pressure in the second piston-cylinder unit; and an evaluation-and-control device that specifies a target force of the first brake booster applied to the second piston of the second piston-cylinder unit, wherein the target force does not influence a brake pressure increase produced by the first piston-cylinder unit.
