Abstract

The invention concerns a drive system, especially for a motor vehicle, with a drive assembly, especially an internal combustion engine (1), and at least one electric machine (4) for active reduction of rotational nonuniformities, acting on the drive assembly, in particular, its drive shaft (10) or a shaft coupled or which can be coupled to it, wherein at least one sensor (16, 32) of the drive system and/or at least one quantity derived from sensor information serves both to control the drive assembly and also to control the electric machine (4), and/or wherein a control unit (31 and 33, respectively) responsible for the control of the electric machine (4) or of the drive assembly also partly or entirely controls the drive assembly or the electric machine (4), respectfully. The invention is also oriented to a method of operating such a drive system.
