Abstract
In normal operation, a control or regulating device controls vehicle rear wheel steering in accordance with freely-selectable specifications. If a malfunction of the control or regulating device is detected, the latter becomes inoperative immediately. A piston-cylinder unit drivingly connected to the front wheel steering and a piston-cylinder unit drivingly connected to the rear wheel steering are simultaneously positively coupled to one another, with the result that the rear wheel steering is actuated positively via the front wheel steering.
