Abstract

This invention relates to an automatically controlled clutch in a motor vehicle drive train. Rotational speed differences between the clutch input and the clutch output are determined by a computer from rotational speeds of the vehicle engine, on the one hand, and rotational speeds of the vehicle drive wheels, on the other hand. Variations of a frequency which is characteristic of resonant frequencies in the drive train when the clutch is closed are not taken into account.
