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.
