Abstract
A method sets the braking effect of the retarder brake as a function of the absolute value of the difference between wheel speed values which are derived from wheel speeds at wheels which can be influenced by the retarder brake and from wheel speeds at wheels which cannot be influenced by the retarder brake. The braking effect is reduced if the absolute value of the difference exceeds a prescribed limit value which is lower than the absolute value of the difference when one of the wheels starts to tend to lock. The effect of the retarder brake can thus already be reduced significantly before the locking point is reached so that the risk of wheels locking which otherwise exists owing to the comparatively slow decrease in braking torque of retarder brakes and thus the associated swerving of the axle of the retarder brake are reliably avoided.
