Abstract: A method for actuating a hydraulic brake system in a motor vehicle, in which a hydraulic brake pressure is generated specific to the wheel, data of a driving environment sensor system being taken into account for detecting the instantaneous lateral distance of the motor vehicle from the desired track.

Abstract: A hydraulic braking system is described having a brake master cylinder (10), at least two brake circuits (30, 32) which are hydraulically connected to the brake master cylinder (10), solenoid valves (58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80) which are individually assigned to the brake circuits (30, 32), and means for supplying voltage pulses to the solenoid valves (58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80), through which the hydraulic pressure in the brake circuits (30, 32) may be modulated, the solenoid valves (58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80) able to be supplied with activations which are individual for each wheel or specific to each brake circuit. Furthermore, a method of influencing a hydraulic braking system having a brake master cylinder and at least two brake circuits is described.

Abstract: The present invention relates to a method and a device for adjusting the braking effect and/or driving effect at the wheels of a motor vehicle. For this purpose, a tire tolerance adjustment has at least two different operating modes. It is determined whether a mounted spare wheel or temporary spare wheel is present. One of the operating modes is selected as a function of the determined existence of a spare wheel.

Abstract: A pressure-actuated valve which includes an effective pressure face by which the valve is opened, the face on which the pressure difference that opens the valve acts is completely independent of an openable flow opening. The effective pressure face and the openable flow opening can be selected arbitrarily within wide limits, independently of one another. The pressure-actuated valve according to the invention is preferably suitable for shock absorbers.

Abstract: A device for actuating a butterfly throttle valve of an internal combustion engine includes a hydraulic setting member for rotating a shaft of the throttle valve. The hydraulic setting member is driven by a branch flow of fuel delivered by a fuel pump and acting as pressure medium. The branch flow passes through a series of connection of adjustable throttles connected in a hydraulic bridge circuit. The throttles are adjusted by a regulating signal corresponding to the difference between an actual position signal delivered by a position sensor coupled to the throttle valve, and a desired position sensor coupled for example to a gas pedal of the motor vehicle.
