A system for the guidance of a vehicle (1 ) with at least one undriven support axle (2) provided with wheels following in the normal direction of travel of the vehicle after the front wheel axle (3) of the vehicle comprises a control circuit (7) for the support of the function of a control means (5) that has the nature of a steering wheel, a force arrangement (9) designed to transfer force onto the support axle in order to guide the alignment of its wheels (13), and a control unit (8) designed that control the force arrangement. An arrangement (15) is designed to determine whether the vehicle is in a normal condition with respect to the system or in a special condition with respect to the system with an increased need for support of the function of the control means relative to the normal condition of the vehicle. The control unit (15) is designed to control, when the special condition of the vehicle has been determined, the force arrangement to transfer force to guide the angular displacement of the wheels (13) of the support axle according to a relationship with larger angular displacement relative to the angular displacement of the wheels (6) of the front wheel axle than during the said normal condition. |
