Beschreibung
Zusammenfassung:	A damping arrangement for dampening rotational irregularities in a drive train of a motor vehicle, having a slip arrangement providing slip between an input and output region of a torque-transmitting arrangement. The slip arrangement has a closed-loop control device that performs closed-loop control of the slip dependent on a measured signal for a rotational irregularity. The closed-loop control device performs closed-loop control of the slip dependent on at least one characteristic variable of a periodic oscillation component of an alternating component of a rotational speed proceeding from an average rotational speed. A sensor device is connected to the closed-loop control device and is designed to ascertain the average rotational speed in the torque-transmitting path downstream of the slip arrangement and to ascertain a frequency of the alternating component in the torque-transmitting path upstream of the slip arrangement.
