Abstract
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.
