Abstract
A vehicle steering device has a single electric motor which, at the same time, introduces energy for desired rotational speed conversion and auxiliary power support into the system. Steering interventions by a driver of the vehicle, in the form of a driving moment exerted by a vehicle steering wheel, are superimposed with a driving movement of the electric motor, and these two motors are initiated jointly onto a driving element.
