Abstract
The invention concerns a drive system with a drive motor ( ), especially an internal combustion engine of a motor vehicle, and a drive train ( ); an electric machine ( ), which can apply a braking and/or driving torque to the drive motor ( ) and/or drive train ( ) and/or form a coupling in the drive train ( ); 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 ( ) 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 ( ) 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 so that it diminishes the torque and/or speed fluctuations (Step C).
