Abstract
An adjustment device as well as a corresponding method for operation of the final control element in a motor vehicle are specified. In this case, a motor is provided for operation of the final control element, a sensor element is provided for detection of a parameter that characterizes the motor and a control unit, which is connected to the sensor element and to the motor, is provided for control of the motor. The control unit is designed to record the profile of a parameter that characterizes the motor, or of a signal that is derived from it, over the actuating movement, to compare the recorded profile with a switching-off threshold that is dependent on the actuating movement, to stop and/or to reverse the drive if the switching-off threshold is exceeded, and to change the switching-off threshold as a function of the time for which the final control element is switched off. This allows reliable jamming protection, in which the probability of spurious detection of jamming is reduced.
