Abstract
A method for operating a steering system of a vehicle, wherein the steering system comprises a steering mechanism and at least one electric motor cooperating with the steering mechanism, and wherein a stiffness of a steering assembly of the steering mechanism and/or play in the steering mechanism is determined includes determining the stiffness of the steering assembly and/or play in the steering mechanism. The steering mechanism is brought into a defined test position and/or blocked in the test position and the electric motor is actuated with an excitation signal, and the stiffness of the steering assembly and/or play in the steering mechanism is determined in that, during the actuation of the electric motor with the excitation signal, a motor torque of the electric motor and a rotor orientation angle of the electric motor is monitored and a change in the motor torque is evaluated according to the rotor orientation angle.
