Window glass lifter for vehicle and method for operating window glass lifter

Abstract

The invention relates to a window glass lifter for a vehicle and a method for operating the window glass lifter. In the operating process of the window glass lifter, window glass (2) of the vehicle is opened completely or partially and closed again in the work cycle by means of a servo motor (3) of the window glass lifter (1). In this way, in the work cycle, the metric (x') of the adjustment position (x) of the window glass (2) is worked out according to the operating parameter (phi) of the servo motor (3). In the standardization process following the work cycle, when the window glass (2) is driven and controlled for at least a preset period of blocking time after being driven and controlled by the servo motor (3) to exceed the upper blocking position, the metric (x') of the adjustment position (x) of the window glass (2) is standardized to a reference value. Otherwise, when the window glass (2) is driven and controlled by the servo motor (3) in the time period not exceeding the blocking time after reaching the upper blocking position, the window glass (2) is completely or partially opened again automatically.

Description

technical field [0001] The invention relates to a window regulator for a vehicle, in particular a motor vehicle. The invention also relates to a method for operating such a window regulator. Background technique [0002] Motor-driven window lifters are generally used in motor vehicles to move movable window panes, in particular side panes, of the motor vehicle between their closed position and their open position. For this purpose, the window regulator usually includes an electric servomotor, which is coupled to the window pane via an adjusting mechanism, and a control unit for controlling the servomotor. [0003] Such window regulators are generally designed to additionally carry out an automatic adjustment process in addition to a manually controlled adjustment process, the entire process of which is controlled by the vehicle user via operating buttons or other commands. The transmitter is controlled. Such an automatic adjustment process can either be triggered by the v...

Problems solved by technology

[0011] Reliable recognition of the upper blocking position (the upper blocking position is a prerequisite for permanently blocking the movement of the window over the entire blocking time) cannot be guaranteed in this case, since the actuating button can be released by the user at any time

Experience has shown here that the operating button is often released too early, so that the blocking position cannot be detected

This can lead to non-standardization over many successive working cycles, which in turn can lead to successively larger deviations of the logical and mechanical adjustment positions and—if the deviation is sufficiently large—resulting in the raising and lowering of the windows involved organ dysfunction
