A device for controlling vibrations generated by electric machines of a vehicle is provided. The vehicle includes a first electric machine unit for driving a first wheel and a second electric machine unit for driving a second wheel. The device is configured to operate the first electric machine unit depending on a first torque to be applied to the first wheel and to operate the second electric machine unit depending on a second torque to be applied to the second wheel. Furthermore, the device is configured to operate the first electric machine unit and the second electric machine unit in a manner coordinated to one another such that predefined target vibrations can be generated as a result of the superimposition of first vibrations caused by the operation of the first electric machine unit and second vibrations caused by the operation of the second electric machine unit.
