Abstract

The invention relates to a method for reducing chatter in automotive drive train which comprises an internal combustion engine as the drive and a clutch device. According to the method, a rotating component of the drive train is driven by means of the internal combustion engine and the speed of the component is detected. Any chatter is also detected. When chatter occurs, an electric motor is used to transmit a torque onto the rotating component in order to actively dampen the chatter. The rotating component is driven by the electric motor for any chatter component at which the speed of the rotating component decreases and the rotating component is slowed down by the electric motor for any chatter component at which the speed of the rotating component increases.
