Method and device for reducing meshing noise of an electrically drivable drive train of a motor vehicle

摘要

In order to provide a method for reducing meshing noise of an electrically drivable drive train of a motor vehicle with a gear transmission and with an electric machine with which direct and high frequency can be acted upon the electric machine and which allows high dynamics largely independent of control circuits and calculation times, is at A method (100) for reducing meshing noise of an electrically drivable drive train (10) of a motor vehicle with a gear transmission (11) and with an electric machine (12), wherein an alternating torque is superimposed on a current torque, proposed that the alternating torque by a voltage specification for the electric machine (12) by means of power electronics (13) is generated.
