Method and device for the position-dependent control of a mobile element in a motor vehicle
First Claim
1. Method for the position-dependent control of a mobile element in a motor vehicle, wherein the element is movable in a drive movement by an electrically powered positioning device, wherein the positioning device is operable in several different operational modes, and characteristics of a drive signal of the positing device, the characteristics being at least a ripple of a drive current, are used for determination of the position of the element, comprising the steps of:
- at least one of a characteristic variable which is influenced by the drive movement of the positioning device and a specific value which characterizes the positioning device are evaluated for the determination of an error value of the determined position of the mobile element, and controlling the operating modes of the positioning device in dependence of the determined error value.

Abstract
The present invention concerns a method for the position-dependent control of a mobile element in a motor vehicle, wherein the element is movable in a drive movement by an electrically powered positioning device, wherein the positioning device has several different operational modes, and characteristics of a drive signal of the positing device, in particular a waviness of a drive current, are used for the determination of the position of the element. According to the invention, a characteristic variable, which influences the drive movement of the positioning device, and/or a specific value, which characterizes the positioning device, are evaluated for the determination of an error value of the determined position of the mobile element, and that the operating modes of the positioning device are controlled in dependence of the determined error value.
