Title: Method for controlling and regulating a motor-driven adjusting device

Abstract: The invention relates to a method for controlling and adjusting a motor-driven adjusting device, especially a window lifter, a seat adjusting device or a sliding roof of a motor vehicle, comprising an anti-jamming protection. The motor drive is switched off or blocked at a value below a predetermined load limit when said predetermined load limit is exceeded. The aim of the invention is to provide a method with which the adjusting device is subjected to as little loads as possible under all operating conditions. To this end, state variables of the motor drive are continuously detected and the load actually generated by the motor drive is determined from said state variables on the basis of a mathematical model of the drive.
