In the case of a window lift, these end positions are predetermined by the closed position and the opening position of the vehicle window.
  • the adjusting mechanism of such a control device usually comprises a drive screw coupled to the drive shaft of the servo motor and a worm wheel meshing therewith.
  • the closed position is often not fixed in a window regulator. Rather, the actuator for the window is adjusted only after installation in a vehicle to the closed position of the vehicle window.

  • the thus determined closed position of the window pane is usually deposited in a control unit of the adjusting device.
  • the window pane is then held by the adjusting device usually just before the stop on the vehicle frame.

  • the mechanical stress transmitted by the vehicle frame to the vehicle window is absorbed by the adjusting device.
  • the worm wheel of the adjusting mechanism with respect to the drive screw with a torque of typically up to 5 - 20 Nm braced. Due to this stress, a deformation of the worm wheel, which usually consists of plastic, can occur. This deformation can affect the function of the actuator. In particular, a deformation of the worm wheel can lead to a non-circular running of the actuating mechanism. This, in turn, may provide other functions of the actuator, e.g. impair the function of an automatic anti-trap protection provided if necessary.

At a high outside temperature and / or under strong sunlight, it may well in the typical installation environments of an adjusting device, especially in a vehicle door, come to temperatures that reach or exceed 80 0 C. Under these circumstances, the plastic of the worm wheel or optionally further plastic components of the adjusting mechanism is relatively soft and tends to undergo plastic deformation under mechanical stress.

  • the vehicle interior or vehicle outside temperature is here preferably in the context of an external vehicle component, e.g. an on-board computer, detected and the adjusting device provided via a CAN bus or other data transmission connection.
  • a calculated actuator motor temperature is used as the temperature parameter. In the context of a conventional adjusting device, this actuator temperature is often calculated anyway by means of an overheating protection provided there in accordance with the standard and is thus already available within the scope of many conventional adjusting devices.
  • the threshold value of the actuating speed measured variable used as a condition for the detection of the end position is preferably set to zero, so that in this case the reaching of the end position is recognized by the fact that the actuating speed completely comes to a standstill.
