Claim:
1. A method for operating a power steering system comprising an electronic processor for computing a motor torque, an electric motor for introducing the motor torque, and a device for detecting a measured manual torque, the method comprising: computing the motor torque by the electronic processor as a function of the measured manual torque; correcting said measured manual torque by either one of adding or subtracting a value of added torques of at least one special function to said measured manual torque to achieve a corrected manual torque that equals the measured manual torque plus or minus said value of added torques of said at least one special function; substituting the corrected manual torque for the measured manual torque as an input to a plausibility check of the computed motor torque; performing said plausibility check of the computed motor torque by the electronic processor based on said corrected manual torque; and introducing the computed motor torque by the electric motor in dependence of a result of performing the plausibility check.
