Abstract: The present invention relates to a method for estimating vehicle speeds independently on front and rear wheels of a four-wheel motor vehicle on the basis of front wheel speeds and rear wheel speeds, for use as a basis for determining slip rates for front and rear wheels. According to the first method of the invention, a reference wheel speed determined by the vehicle speed as estimated from the left and right wheel speeds cannot be unnecessarily increased during turning of the vehicle. According to the second and third methods of the invention, the estimated vehicle speed largely does not deviate from the actual vehicle speed in the event of a phase difference of variants produced between the left and right wheels due to an anti-lock control during the turning of the vehicle.
