Powertrain and method of reducing tooth meshing noise of an electrically driven drive train with a gear transmission

There are proposed a drive train and a method for reducing a meshing noise of an electrically driven drive train (10) with a gear transmission (2) and an electric motor (1). The method comprises the steps of: - determining an operating state of the drive train (10), - reading out a associated with the determined operating state record from a data memory (3), and - adapting a torque of the electric motor (1) corresponding to the record.
