Abstract
A method for operating a steering system and such a steering system are presented. The steering system includes a steering wheel which acts on a steering rack via a steering pinion of a steering column, wherein a steering torque is transmitted to the steering rack by means of the steering wheel. Furthermore, a steering assistance unit is provided, by means of which a steering assistance torque can be applied to the steering rack. A control circuit with which the steering assistance torque is regulated, is used, wherein the control circuit takes into account the mass inertia of the steering column.
