Procedures for influencing and, where appropriate. Control of rotational states in a multi-coupling drive train

摘要

Method for generation or alteration of rotational movement conditions in a motor vehicle drive train with drive unit, gearbox (36), with at least two gear shafts, and coupling arrangements linked together. A torsion vibration damping arrangement is provided that varies slip in the two couplings of the drive train, dependent on the rotational velocity or acceleration of the drive train components in order to reduce rotational vibrations. ??The invention also relates to a corresponding motor vehicle drive train with a double coupling arrangement (32, 34) and means for limiting rotational vibrations.
