Control device and method for controlling window lifter with Anti-trap protection for motor vehicle

Abstract

The invention relates to a control device for controlling an externally-powered window lifter with anti-trap protection for a motor vehicle window. The control device of this type is designed to determine that an operating element for closing the window is actuated and, in response thereto, the window is moved in the closing direction. The control device is further designed to determine that the functional activity of the anti-trap protection is no longer guaranteed. In the case of a control device and in the event that it has been determined that the functional activity of the anti-trap protection is not guaranteed, the window lifter is actuated in response to the actuation of the operating element in such a way that the window is moved at a lower displacement speed in the closing direction when compared with the displacement speed with guaranteed functionality. In the case of an alternative control device and in the event that it has been determined that the functional activity of the anti-trap protection is not guaranteed, the window lifter is actuated in response to the actuation of the operating element with a predetermined actuation sequence of the window lifters in such a way that the window is displaced in the closing direction starting from the idle state.

Description

technical field [0001] The invention relates to a control device and a method for controlling a window regulator with pinch protection for windows of a motor vehicle according to the preambles of the co-claims. Background technique [0002] In modern motor vehicles, especially passenger cars, externally operated window regulators, in particular electric window regulators with electric motors, are installed for essentially vertically raising and lowering the windows. The window pane without the operator himself having to exert force for moving the window pane (for example via a crank handle). The windows are usually closed by raising the window glass and opened by lowering the window glass. [0003] A distinction is made between manual closing and automatic closing when the windows are closed by force-operated window regulators. [0004] When closing manually, the window is closed along the edge as soon as the associated operating element, such as the window regulator opera...

AI Technical Summary

Problems solved by technology

If just in this very improbable situation the additional closing force limitation does not function at all or does not function sufficiently and in addition the body part is located in the area of ​​movement of the window, this can lead to pinching with very low probability, at least in theory and may cause injury to persons
