Abstract
A braking system may include a brake booster, the piston-cylinder system of which is driven by an electric motor, wherein at least one working chamber of the piston-cylinder system is connected by hydraulic lines to at least two wheel brakes, a wheel brake being allocated a 2/2-way switching valve in each case and the hydraulic connection lines between the wheel brakes and the piston-cylinder system being closable, optionally separately or jointly, by means of the 2/2-way switching valves, so that a pressure can be adjusted in the wheel brakes one after the other in terms of a multiplex method and/or simultaneously. The electric motor and switching valves may be activated by a control device configured to adjust or control the piston movement and piston speed during the pressure generation and pressure reduction as a function of the pressure-volume characteristic of the wheel brakes.
