Abstract
To prevent slipping or spinning of a driven wheel which, selectively, can be braked or supplied with reduced torque from a vehicle engine, a reference speed is determined against which slipping or tendency to slip is measured. The reference value for slip measuring, derived from non-driven or rolling wheels, is tested for physically impossible conditions and, if such physically impossible conditions obtain, they are disregarded when determining slipping or tendency to slip. Proper speed values can be stored, utilized for subsequent measurement, directly or modified, which may also be made speed dependent, or dependent on differences between the speeds of two rolling wheels.
