Abstract
A method actively dampens a start-up resonance of a torsional damper when starting an internal combustion engine. The torsional damper () is fixed between an internal combustion engine () and a secondary side () of a torsional elasticity, and the internal combustion engine () is started using a starter generator () arranged on a side of the internal combustion engine () counter to the torsional elasticity. A counter excitation is applied to a torque generated by the starter generator () when the internal combustion engine () is started, which counter excitation is modulated on the basis of a parameter of the internal combustion engine () which changes when the internal combustion engine () is being started.
