Abstract
The supplementary steering system operates automatically as a function of the change of the transverse velocity (v.sub.y) of the vehicle to provide compensation steering movements to stabilize a vehicle in skidding situations. The system relies on the fact that a great increase invehicle transverse velocity is characteristic of skidding movements. Critical travel conditions can be stabilized by a rapid reaction to the change of transverse velocity. Under steady travel conditions, i.e., when only a negligible change of transverse vehicle velocity occurs, the supplementary steering system is not actuated, or is reset to its central position.
