<p>Damping device for suppressing torsional vibrations in the drive branch (3) of an internal combustion engine (1) comprises a detection device for determining a mechanical state variable ( Delta alpha MODELL, Delta alpha IST, alpha 1, alpha 2, alpha '1, alpha '2) reproducing the torsion of the drive branch, and a control device (2) for controlling the engine with a control variable (m) according to the determined state variable. The detection device has a predictor element (4) that contains a model of the drive branch and/or the engine and determines the state variable ( Delta alpha MODELL, alpha 1, alpha 2, alpha '1, alpha '2) in response to the control variable using this model. The model has adaptable model parameters. - Independent claims are also included for: - (1) Engine control device comprising the above damping device; and - (2) Damping process for suppressing torsional vibrations in the drive branch of an internal combustion engine.</p> |
