Method for operating electronic power steering system of motor vehicle, involves predetermining steering angle as measure for desired wheel steering angle from steering wheel of motor vehicle by steering handling device

摘要

The method involves predetermining a steering angle (Delta-S) as a measure for a desired wheel steering angle (Delta-Fm) from a steering wheel (5a,5b) of a motor vehicle by a steering handling device (2). A torque boost of an electric servo drive (12) is deactivated at a steering position in an area before a mechanical end stop of a gear rack (6) of a steering gear (4) and at a drive speed of the vehicle from approximately zero such that no further position of the gear rack or rack stroke takes place in direction of the mechanical end stop. Independent claims are also included for the following: (1) a computer program with program code unit for the execution of an electronic power steering system operating method; and (2) a computer program product with program code unit.
