1. Method for controlling and regulating a motor driven adjusting device, more particularly a window lifter, seat adjuster or a sun-roof, of a motor vehicle with an anti-jamming protection, wherein input variables of the motorised drive are continuously detected and the actual load of the adjusting device or motorised drive is determined through systems of equations which were set up using a mathematical model of the complete adjusting device including the drive, and on exceeding a predetermined load limit the motorised drive is switched off or regulated to a value below the load limit, characterised in that the continuously detected input variables are converted into individual force components (F mot, F Beschl, F res, F s&plus;h ) which contribute to increasing or reducing the overall load (F Einkl ) of the adjusting device or individual components of the adjusting device and which are entered with a positive sign into the calculation of the actual total load (F Einkl ) of the adjusting device or drive, which depends on whether the relevant force component (F mot, F Beschl, F res, F s&plus;h ) assists the adjusting movement of the adjusting device or drive or counteracts the adjusting movement of the adjusting device or drive.
