Abstract

The invention concerns a drive system with a drive motor (1), especially an internal combustion engine of a motor vehicle, and a drive train (27); an electric machine (26), which can apply a braking and/or driving torque to the drive motor (1) and/or drive train (27) and/or form a coupling in the drive train (27); and an open-loop/closed-loop control system, which controls/regulates the electric machine such that it diminishes drive train torque and/or speed fluctuations. Moreover, the invention concerns a method for operating such a machine (26) in a drive system, wherein a drive train time function of the torque and/or speed is controlled/regulated, and in particular smoothed out, with the steps a) detection of the drive train torque and/or a rotary speed of the drive train (27) and/or a quantity derived from these quantities (Step A); b) determination of the torque and/or speed fluctuations (Step B); c) actuation of the electric machine 26 so that it diminishes the torque and/or speed fluctuations (Step C).
