    Abstract: Using a model calculation, desired changes in the yaw rate .DELTA..phi. and the transverse acceleration .DELTA.y are determined from a small change actually made in the steering angle and are compared to measured quantities .DELTA..phi..sub.F and .DELTA.y.sub.F determined on the vehicle. The deviations of the actual values of yaw rate and transverse acceleration from the calculated values are weighted using predetermined weighting factors for the relative importance of yaw rate and transverse acceleration and supplied with factors dependent on the individual wheel; finally, the values relating to the same wheel are added. They represent desired changes in the brake slip values and a controller finally converts these into brake slip value changes.

    Abstract: A brake-pressure controller regulates the brake pressure on the individual wheels according to the instantaneous slip values in comparison with variable desired slip values. The angle of inclination of one wheel of each axle is determined, and the desired slip values are varied as a function of these angles of inclination with the effect of a better vehicle controllability.

    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 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.

    Abstract: A lower limiting value of the yaw speed is calculated as a function of the steering angle, the vehicle speed, and the coefficient of friction between tires and road. If the yaw speed falls below the lower limiting value, the brake pressure is reduced in order to increase lateral stability.
