Method for operating an electric power steering system of a motor vehicle and electric power steering system for a motor vehicle

摘要

The invention relates to a method for operating an electric power steering system (1) of a motor vehicle (50), in which by means of a steering handle (2) a steering wheel angle as a measure of a desired Radlenkwinkel for at least one steerable wheel (5) of the motor vehicle (50) is specified in that an electric servo drive (8) with an electric motor (9) provides steering assistance, and wherein an additional restoring force (20) is provided depending on temperature to compensate for increased internal friction of the power steering system (1), the additional restoring force (20) depending on a steering input detected at the steering handle (2) is reduced. Furthermore, the invention relates to an associated electric power steering system (1), an associated computer program and an associated control unit (11).
