摘要： A pneumatic brake booster (10) has a booster housing (12), the interior of which is subdivided by at least one movable wall (22) into a vacuum chamber (24) and a working chamber (26). Projecting into the booster housing (12) is a control valve (28) which, after a response force acting counter to its operating direction has been overcome, controls a pneumatic pressure difference acting upon the movable wall (22). The control valve (28) is operable both by means of a mechanical input element (36) and, independently thereof, by means of an electromagnetic arrangement (48) comprising a coil (58) and an armature (50), which are displaceable relative to one another along the operating direction. To reduce the response force which has to be overcome by a user, a device for detecting an operation of the control valve (28) effected by means of the mechanical input element (36) is provided which, once such an operation has been detected, during said operation prompts an energizing of the electromagnetic arrangement (48) of an intensity sufficient to reduce the response force of the control valve (28) yet not increase the braking force provided by the brake booster in accordance with the operation.

摘要： A hydraulic pressure generator for a vehicle brake system comprises a piston and a cylinder that movably accommodates the piston. The piston defines a first hydraulic chamber and a second hydraulic chamber in the cylinder on opposite piston sides, wherein each hydraulic chamber has a hydraulic inlet and a hydraulic outlet. An actuating unit is able to put the piston into a back-and-forth motion so that an intake stroke with regard to the first hydraulic chamber corresponds to a discharge stroke with regard to the second hydraulic chamber, and vice versa.

摘要： In an electronically controllable brake booster a value is sensed which is characteristic for the actual pressure characteristic in the pressure chamber. The actual pressure characteristic is checked for the existence of periodic oscillation components of a predetermined frequency band with a predetermined minimum amplitude. Upon the existence of such periodic oscillation components, the current flowing through an electromagnetic actuator for a control valve arrangement of the brake booster is decreased by a first predetermined value for a first pressure changing position. Further, the current for a second pressure changing position is decreased by second predetermined value.

摘要： The invention utilizes the finding that a pressure variation or pressure difference between two chambers of a brake booster is a parameter of considerable influence on the behavior of a brake booster control valve arrangement in the operation of the brake booster. Starting from a holding position for the control valve arrangement, pressure levels related to changeovers from the holding position to a first pressure changing position and a second pressure changing position, respectively, are determined. Depending on the thus determined pressure level differences, current values for an actuation of the control valve arrangement defining upper and lower limits for the holding position are adjusted.
