Abstract
In a control unit and a method for operating a hybrid drive arrangement () with an internal combustion engine (), an electric drive () and a coupling device () that is arranged therebetween, when the internal combustion engine () and the electric drive () should be coupled together, the rotational speed of the internal combustion engine () is pilot-controlled to a target rotational speed level (N) such that the drive shafts () of the internal combustion engine () and the electric drive () run at least approximately synchronously. The pilot-control takes place by the throttle valve. Subsequently, the rotational speed of the internal combustion engine () is controlled in such a manner that the drive shafts () of the internal combustion engine () and the electric drive () run essentially synchronously. Then, the drive shafts () are joined by the coupling device ().
