Abstract
A method for assuring that a signal, for damping drive train vibrations, is overlaid during the same time period as the drive train vibration, and not delayed by one time period. The method comprises the steps of continuously calculating a correction torque for the vibration damping, determining, through a parallel signal path, whether the vibration damping is to be activated or deactivated, and overlaying the correction torque to the drive train vibration, if the necessity arises for activation of the vibration damping.
