Abstract: A method of coordinating a plurality of intervention measures into a driving performance of a vehicle includes determining a wheel slip angle of a front axle, determining a coefficient of friction on the front axle, determining a wheel slip angle threshold value, comparing the wheel slip angle to the wheel slip angle threshold value, and initiating a first intervention measure through at least one of a brake system of the vehicle and a drive system of the vehicle if an absolute value of the wheel slip angle is greater than an absolute value of the wheel slip angle threshold value.

Abstract: A method and a device for the control of a vehicle brake system are described. In this context, the setpoint values for each wheel are corrected based on the difference between brake pressures in at least one wheel brake of two different brake circuits.

Abstract: A method for estimating the pressure, i.e., pressure stroke, in a wheel brake cylinder, in particular in connection with a vehicle stability control system for calculating an effective control time, assignable to an instantaneous controller cycle, of an PWM-controlled valve actuating the wheel brake cylinder, on the basis of an actual control time definable by a control unit during the instantaneous controller cycle or an effective control time assignable to a preceding controller system and a valve stroke relative to a maximum stroke; and for calculating a pressure stroke of the wheel brake cylinder between two consecutive controller cycles, based on a valve pressure/volume characteristic retrievable from the control unit; an effective pressure difference across the valve; and the calculated effective control time.

Abstract: A method and apparatus for calculating the actuation control of a hydraulic sub-system of a braking system in order to reduce noises associated with the hydraulics is presented. Input signals and measured/determined characteristics are utilized to calculate a value of a drive time for an inlet valve, a value of a pulse width modulator output, a duration of a current signal reduction time and a pulse width modulator value associated with the current signal reduction time, all of which determine actuation control of the hydraulic sub-system.

A device for coordinating intervention measures into the driving performance of a vehicle is also described.

Abstract: A method and a device for determining a quantity describing the brake circuit pressure, with which the brake circuit pressure is determined for a pressure buildup, in particular a pressure buildup independent of the driver, and also for a pressure reduction. In a pressure buildup independent of the driver, the delivery performance of the pump which delivers the brake medium and is detected with sensing means is taken into account in determining the brake circuit pressure. In a pressure reduction, the brake circuit pressure is determined as a function of a quantity which describes the brake circuit pressure to be expected after the pressure reduction.

Abstract: A method and a device which are used for forming and/or adapting a driving signal of an arrangement for delivering a pressurized medium in a braking system. The driving signal, in particular, of a pump of a braking system, is a function of at least one driving signal and/or the formation of the driving signal of a shut-off device, in particular, of at least one valve, for the inlet and/or outlet and/or passage of the pressurized medium. A delivery rate of the pump is adapted in a manner compatible with the situation, including the valve position resulting from the driving signal and/or its formation and/or the prevailing pressure ratios.

Abstract: A device and a method for controlling an ABS antilock braking/ASR traction control system include a return pump, at least one aspirator valve (ASV), and at least one switch-over valve (USV). The return pump, the switch-over valve and/or the aspirator valve are triggered at least in dependence upon one signal which represents the actuation of the brake pedal.

Abstract: When a threshold value is exceeded by the rate of change in the input pressure, an automatic braking operation is initiated. The threshold value becomes lower as the potential for danger increases.

Abstract: A leveling system for vehicles has one pressure regulating valve for controlling each work cylinder disposed between the vehicle body and a wheel support, the work cylinder having a hydraulically controlled main valve and an electromagnetically controlled pilot valve. To avoid uncontrolled motion of the vehicle body upon start-up, the pilot valve has a valve piston controlled by an electromagnet and acted upon in the valve closing direction by pressure in the control chamber of the main valve, which chamber communicates with a fluid source via a throttle, and in the valve opening direction by the pressure in the work cylinder. The valve piston has a valve seat, cooperating with a fixed valve member. The valve inlet of the pilot valve communicates with the control chamber, and its valve outlet communicates with a fluid tank. The main valve has three valve positions.
