  • Patent number: 5236056
    Abstract: A method for assisting the steering forces to be produced in a vehicle by means of an electric motor acting on the steering column is proposed. This method is characterized in that the additional torque produced by the electric motor is controlled in dependence upon the steering torque to be produced for actuating the steering and upon the steering torque supplied overall. The additional torque is thus dependent on the torque which is produced at the steering wheel by the driver and, in addition, on the torque which is supplied by the steering arrangement on the wheels to be steered. The electric motor is controlled by a controller 5 via an actuator 6, an additional torque M*.sub.R, which is dependent on the vehicle speed, being input into the controller. As characteristic shaper, the controller has a dead-time element by which the control intervenes only from a certain limit value of the torque M*.sub.R input into the controller 5.
