The invention relates to a method for operating a drive train (2) having an electromotive drive (4), wherein a speed and a drive torque of the electromotive drive (4) can be converted via a toothed transmission stage (12) for an output (19), and the electromotive drive (4) is controlled with a control signal (40), wherein a periodic torque change signal (5) which alternately reduces and amplifies the drive torque is superimposed on the control signal (40) in order to damp transmission noises, wherein the periodic torque change signal (5) is in phase with a periodic change in the tooth stiffness of the toothed transmission stage (12). The method according to the invention proposes, on the basis of a software architecture extended by machine-learning knowledge, detecting a change in state of the drive train over the service life that can be attributed to a long-term change in the tooth stiffness of the transmission stage, and based on these changes, to adjust a torque control in such a way that progressive noise effects caused by ageing or wear can be better damped.
