    • 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.

    • An anti-skid brake control system for a motor vehicle includes at least one sensor for determining the deceleration V.sub.R of a vehicle wheel, a device for determining the deceleration V.sub.F of the vehicle, a device for determining the difference D of the vehicle and wheel decelerations (D=V.sub.F -V.sub.R), a control circuit responsive to the difference D for producing brake pressure control signals, and a brake pressure control device for increasing and decreasing the given brake pressure in response to the control signals from the control circuit. The difference D is also supplied to a ladder filter. During phases in which brake pressure is maintained at a constant level, the ladder filter is switched to identification by the control circuit and determines a reflection coefficient. The control signals then affect the brake pressure so as to select a slippage value on a stable branch of the .mu. slippage curve and near its maximum is derived from the distance of the reflection coefficient from the value "1".

    • Circuitry is disclosed for converting an input measurement signal V.sub.R(i), which is disturbed at least occasionally by a disturbance function, into an output, undisturbed signal V.sub.R(o) by means of a first digital adaptive filter having variable filter parameters. A control circuit is provided to change to parameters of the second adaptive filter to improve the ability of the system to filter out the disturbance signal. The apparatus includes a series circuit formed by a high pass filter and a second digital adaptive filter, coupled to receive the input signal V.sub.R(i). The control circuit switches the second adaptive filter to the adaptation mode, for determining the filter parameters necessary for suppression of the disturbance function n, when essentially only the disturbance signal reaches the second adaptive filter. Thereafter, the filter parameters of the second adaptive filter are transferred to the first adaptive filter to improve the performance of the first adaptive filter.
