Abstract

Load cycle oscillations in the drive train of a motor vehicle are reduced by detecting a change in available torque in the drive train, determining the period of a load cycle oscillation, and, at the commencement of the available torque change, applying at least one additional torque pulse, which causes an oscillation in phase opposition to the load cycle oscillation and which lasts half the period of the load cycle oscillation.
