A method for operating an electric power steering system of a motor vehicle, wherein a steering wheel angle is specified by a steering handle as a measurement for a desired wheel steering angle for at least one steerable wheel of the motor vehicle, wherein an electric servo drive having an electric motor provides steering assistance, and wherein an additional restoring force is provided to compensate for increased internal friction in the power steering system based upon temperature, wherein the additional restoring force is reduced based upon a desired steering direction that is detected at the steering handle. Also disclosed is an associated electric power steering system, an associated computer program, and an associated control unit.
