ABSTRACT:
A power-assisted steering system for a vehicle such as an automobile or truck and having an electro-mechanical servo drive. The servo drive directs the wheels to be steered which are journalled on a wheel carrier assembly and coacts with a steering wheel of the vehicle. The steering system includes a controller to which a steering wheel torque and a steering torque are supplied for forming a control difference with the steering wheel torque being generated by the driver when steering. The steering torque is the actuating torque occurring between the servo drive and the wheel carrier and the forces developed on the steering wheel are controlled to pregiven values while considering the mechanical reaction.
