Abstract: The present invention relates to an electronic controlling device with a computer unit installed to control a regulating device especially a window lifter of a motor vehicle. The computer unit stops or initiates the stop of a regulating motion of the window lifter drive if a signal correlating to the rotary moment of the window lifter drive exceeds a response level. In the setting range of a starting motion from standstill of the window lifter drive, the response level is a setting range dependant and/or time-related dependant preset function with at least one parameter determining the course of this function. The parameter value is modified in dependence from the starting motion of the window lifter drive.

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.
