Abstract
Disclosed is a method for operating a power steering system and to such a power steering system. A manual torque predetermined by a driver is superimposed in a superposition unit with a motor torque created by a motor. Impairment of the power steering system can thus be detected by evaluating rotational speed patterns of the motor.

A method for operating a power steering system of a motor vehicle, in which a predetermined manual torque is superimposed in a superposition unit by a motor torque applied by a motor, impairment of the power steering system is being detected by evaluating rotational speed patterns of the motor.
A power steering system comprising a steering handle for predetermining a manual torque;
- and a superposition unit with which the predetermined manual torque is superimposed with a motor torque of a motor, the power steering system being arranged such that impairment of the power steering system is detected by evaluating the rotational speed patterns of the motor.
