Abstract
A method for monitoring wheel speeds, having the following steps: Determining the wheel speeds (S ), determining the wheel having the maximum wheel speed (S ), determining the wheel having the minimum wheel speed (S ), determining the speed difference between the maximum wheel speed and minimum wheel speed (S ), and comparing the speed difference to a threshold value (S ), deep snow or road conditions of comparable effect being inferred if the speed difference is greater than a threshold value and the slowest wheel has changed exactly once and the fastest wheel has changed exactly once or the slowest wheel has not changed and the fastest wheel has not changed and the speed difference between a driven axle and a non-driven axle exceeds a threshold value.
