1. A method for positionally controlling an electric drive (21), characterized by the following method steps:

  • determining the actual position (δ

    SW) of a steering device (1);

    converting said actual-position-(δ

    SW) into a setpoint (δ

    SW, set) for the position of said electric drive (21);

    detecting an actual value (δ

    pinion) of the position of said electric drive (21);

    generating a control difference (δ

    SW

    δ

    pinion) between said setpoint and said actual value of the position of said electric drive (21);

    adjusting the position of said electric drive (21) according to said control difference (δ

    SW, set

    δ

    pinion);

    adjusting a restoring force acting on said steering device (1) or a restoring torque (MH) acting on said steering device (1) according to the torques and/or forces acting on said electric drive (21) or generated via a family of characteristic curves or a performance graph.
