Abstract: A method for controlling a braking system in an all-wheel drive vehicle having a viscous coupling or a viscous lock, wherein a viscous torque acting on a wheel is estimated, the viscous torque is taken into account in estimating a desired braking pressure for the wheel, and the desired braking pressure is applied to the wheel.

Abstract: Brake pressure is varied briefly by means of pressure pulses at regular intervals during phases when brake pressure is otherwise maintained constant, and any variations in transverse acceleration at each axle are determined. These variations at the axles are used to modify the wheel slip by varying the brake pressure in order to increase stability while retaining an adequate steerability reserve or vice versa.

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 method for improving the controllability of motor vehicles during braking wherein desired slip values are determined and adjusted with the aid of a wheel slip controller. According to the method, the following are measured: the yaw rate .psi., the steering angle .delta., the wheel speeds V.sub.Ri, the inlet pressure P.sub.inlet or wheel brake pressure P.sub.i, and, if required, the engine speed and the throttle valve angle. The following variables are estimated using the measured values: the longitudinal vehicle speed V.sub.X, the longitudinal vehicle acceleration V.sub.X, the wheel slip values .lambda..sub.i, the braking forces F.sub.Bi, the tire forces F.sub.Ri, and the transverse speed V.sub.Y. Desired slip values .lambda..sub.i * are then determined from these measured and estimated variables with the aid of a simple vehicle model and supplied to the slip controller to control the vehicle wheel brake pressure.
