In order to ascertain the actuating position of a vehicle part that is moved by an electric actuating motor via an actuating mechanism, an angle of rotation correlating with the number of motor shaft rotations during the actuation process or a motor signal correlated therewith are ascertained during an actuation process. An actuating position measure for the actuating position of the vehicle part is derived from the angle of rotation or the motor signal correlating therewith. During this process, an unloaded angle of rotation, through which the motor shaft rotates during an initial no-load phase of the actuation process without motion of the vehicle part is compensated by a predetermined correction term. The correction term is changed according to a stored dependency on a characteristic quantity for the age of the actuating mechanism.

Precise ascertainment of actuating position for a motor-driven vehicle part

A method is specified for ascertaining an actuating position of a vehicle part that can be moved by an electric actuating motor. The speed of an actuating motor correlated therewith is acquired in a time-resolved manner during an actuation process. An initial no-load phase of the actuation process is identified, during which the actuating motor rotates while overcoming the system tolerance of the actuating mechanism without motion of the vehicle part. An actuating position measure for the actuating position of the vehicle part is ascertained from the motor rotation, with this measure being corrected during the no-load phase. By averaging over time, a test quantity is ascertained from the second derivative or the measured quantity correlating herewith. The end of the initial no-load phase is identified in this process when the test quantity exceeds a predetermined limit.

An anti-trap protection unit for an electric window lifter of a vehicle or generally to efficiently limit excess forces of an adjusting element that can be driven by means of a drive unit is provided. For this purpose, a compensation trajectory of the drive unit is determined independent of the temperature, and a variable threshold function which is dependent on the temperature is determined as a function of the drive trajectory or the drive time, the threshold function approaching a defined threshold value asymptotically, and the drive force especially in the form of a measured speed of a drive motor being continuously determined and being monitored in accordance with the determined threshold function.

Method and device for monitoring a drive unit, especially of a window lifter, comprising a rotating drive motor

A method for monitoring the adjustment movement of a component, in particular a window pane or a sunroof in motor vehicles, which is driven by a drive device and can be adjusted in a translatory or rotary fashion. A plurality of input signals which can be derived from the drive device and which represent a deceleration of the adjustment movement of the drive device are input at input neurons of an input layer of a neural network with at least one hidden layer having hidden neurons. Said network outputting, at at least one output neuron of an output layer, an output value which corresponds to the adjusting force or to a trapped state or nontrapped state.

Method for monitoring the adjustment movement of a component driven by a drive device

A control system for controlling an adjustment device which is operated by electric motor in a motor vehicle includes an indirect anti-trapping system for detecting a trapping situation between an adjustment element, which is moved by the adjustment device in an adjustment movement along an adjustment path, and a vehicle element. The anti-trapping system stops or reverses the adjustment movement of the adjustment element if a defined threshold value for a mechanical running parameter&#x2014;which results from the adjustment movement is exceeded. The anti-trapping system operates with an analysis unit for analyzing the adjustment movement of the adjustment element, wherein the control system is configured and embodied in such a way that by means of the analysis unit, in an analysis mode, the running parameters of the adjustment device can be checked for mechanical functional faults of the adjustment device.
