Abstract

A method is provided for regulating the rotational speed in a hybrid drive of a vehicle having a first drive source, in particular an internal combustion engine, and a second drive source, in particular an electric motor. A rotational speed variable which is a function of a rotational speed of the first drive source and of a rotational speed of the second drive source is determined. The rotational speed of the first drive source or of the second drive source is regulated based on the rotational speed variable for oscillation reduction. The rotational speed variable used is preferably a mean value of the two rotational speeds. The two rotational speeds may be weighted on the basis of inertia in order to form the mean value as well.
