The aim of the invention is to devise an improved anti-trap protection unit for an electric window lifter (5) of a vehicle or generally to efficiently limit excess forces of an adjusting element (4) that can be driven by means of a drive unit (A). For this purpose, a compensation trajectory of the drive unit (A) is determined independent of the temperature, and a variable threshold function (33, 34) which is dependent on the temperature is determined as a function of the drive trajectory or the drive time, the threshold function (33, 34) approaching a defined threshold value asymptotically, and the drive force especially in the form of a measured speed of a drive motor (15) being continuously determined and being monitored in accordance with the determined threshold function (33, 34).
