Abstract
A method for controlling an electric drive machine of a motor vehicle, the drive machine having a rotor shaft which is connected to an output shaft of the motor vehicle via a gear train, wherein, during a load change of the drive machine, a torque provided by the drive machine is adjusted by accelerating the drive machine and decelerating the drive machine by a torque provided by the drive machine, in order to bridge play between teeth of intermeshing gears when switching between the drive flank and the coast flank.

A method for controlling an electric drive machine of a motor vehicle, the drive machine comprising a rotor shaft that is connected to an output shaft of the motor vehicle via a gear transmission, the method comprising:
- setting, during a load change of the drive machine, an acceleration of the drive machine and a deceleration of the drive machine by a torque provided by the drive machine, to bridge a backlash between teeth of gears meshing with one another when changing over between a drive flank and a coast flank.
A control device for an electric drive machine of a motor vehicle, wherein the drive machine comprises a rotor shaft that is connected to an output shaft of the motor vehicle via a gear transmission, wherein the control device is configured to:
- set, during a load change of the drive machine, an acceleration of the drive machine and a deceleration of the drive machine by a torque provided by the drive machine, to bridge a backlash between teeth of gears meshing with one another when changing over between a drive flank and a coast flank.
