Abstract

For the purpose of detecting a jam during the adjustment of a component of a motor vehicle using an adjustment drive, wherein measured values related to the adjustment force (F) are compared to a threshold value (FREF) and when the threshold value is reached, the adjusting movement is slowed or stopped, and optionally reversed, it is proposed that the component speed or a parameter correlated therewith is detected and the threshold value (FREF) modified accordingly.
