Abstract
An active damping system provides a torque adjustment command that is combined with the raw motor torque command of a vehicle to compensate for oscillations and vibrations in the driveline of a hybrid vehicle. Active damping may be provided by a derivative controller or by a lead-lag compensation between initiation of clutch engagement and full clutch engagement. Active damping is terminated upon full clutch engagement.
