    摘要： The invention relates to a braking system having a brake booster, the piston-cylinder system (14, HZ, THZ) thereof being driven by an electrical motor, wherein at least one working chamber of the piston-cylinder system (14, HZ, THZ) is in connection to at least two wheel brakes via hydraulic lines, wherein a 2/2-way switching valve (17a, 17b, 17c, 17d) is allocated to each wheel brake and the hydraulic connection lines between the wheel brakes (18a, 18b, 18c, 18d) and the piston-cylinder system (14, HZ) are separately or commonly closable by means of the 2/2-way switching valves (17a, 17b, 17c, 17d), such that a pressure can be adjusted in the wheel brakes (18a, 18b, 18c, 18d) one after another in terms of a multiplexer process and/or simultaneously, wherein the electrical motor and the switching valves (17a, 17b, 17c, 17d) are activated by a control device and the hydraulic connection line from the working chamber of the piston-cylinder system (14, HZ, THZ) to the respective magnetic valve has a flow resistance RL
    i and each switching valve has a flow resistance RV
    i together with the hydraulic line to the wheel cylinder (17a, 17b, 17c, 17d), wherein the flow resistances RL
    i and RV
    i are small, such that the HZ piston speed determines the pressure reduction gradients and pressure generation gradients in each wheel brake (18a, 18b, 18c, 18d), wherein the flow resistance RL
    i is smaller than the flow resistance RV
    i and the control device regulates or activates the piston movement and piston speed during pressure generation and pressure reduction in dependence on the pressure-volume characteristic curve of the wheel brakes (18a, 18b, 18c, 18d).

    摘要： The invention relates to a brake system comprising a brake booster, the piston-cylinder system (14, HZ, THZ) of which is driven mechanically or hydraulically by an electric motor, in particular by means of transmission means, at least one working chamber of the piston-cylinder system (14, HZ, THZ) being connected to at least two wheel brakes via hydraulic lines, each wheel brake being associated with a 2/2 distribution control valve (17a, 17b, 17c, 17d) and the hydraulic connecting lines between the wheels brakes (18a, 18b, 18c, 18d) and the piston-cylinder system (14, HZ) being selectively disconnectable or jointly closable by means of the 2/2 distribution control valves (17a, 17b, 17c, 17d) such that in the wheel brakes (18a, 18b, 18c, 18d) a pressure can be adjusted consecutively in terms of a multiplex method and/or simultaneously, the electric motor and the control valves (17a, 17b, 17c, 17d) being actuated by a regulating device, characterized in that the regulating device calculates the respective pressure ( p
    R (t) ) in the wheel brakes by means of a pressure model (103) and transmits the calculated pressure values ( p
    R (t) ) to at least one ABS-ESP regulator (104) and to a pressure regulating device (106), wherein the pressure regulating device (106) actuates at least the 2/2 distribution control valves (17a, 17b, 17c, 17d) and the electric motor, and a prioritization device (105) performs a wheel selection on the basis of the data transmitted by the ABS/ESP regulator (104) and transmits it to the pressure regulating device (106).
