Abstract

The slip differential control is used to retard the rotation of one or more of the vehicle driven wheels, as a result of the comparison of the relative rotations of the driven wheels with one another and/or with the non-driven wheels. The vehicle anti-skid device (10) includes a circuit (32) indicating slip of the driven wheels, its output supplied to the control input of a braking device for the driven wheels. Independent magnetic valves (1, 2) are used in addition to the control valves of the anti-skid device, to provide retardation of the driven wheels to limit slip.
