METHOD AND DEVICE FOR DETERMINING THE OFFSET OF AN ELECTRIC WINDOW LIFT SYSTEM

摘要

The invention relates to a method for operating an electric window lift system for electrically moving a vehicle door window by means of a cable, according to which, based on the length change of the cable, the offset of the movement of the window is determined, in which the charge modification of the electric motor is monitored, the offset being used to exactly position (opening, closing) the window.

主权项

1. A method for operating an electric window lift system for electrically moving a window pane for a vehicle door, comprising the following steps:
when a status signal is received, starting a drive motor which is coupled to the window pane via a mechanical connection; and stopping the drive motor at a stop position which depends on a predefined change in position and on a position specification of the drive motor relating to the change in position of the drive motor since the starting; determining an offset which specifies the change in position of the drive motor between the starting of the drive motor and an occurrence of a change in load after a run-up of the drive motor, wherein the stop position also depends on the determined offset.
