11. A method for controlling vibrations effected by electric machine units of a vehicle, wherein the vehicle comprises a first electric machine unit for driving a first wheel of the vehicle and a second electric machine unit for driving a second wheel of the vehicle, the method comprising:
operating the first electric machine unit in dependence on a first torque to be applied at the first wheel;
operating the second electric machine unit in dependence on a second torque to be applied at the second wheel;
operating the first electric machine unit and the second electric machine unit in synchronization with respect to each other so as to effect predefined target vibrations by superimposing first vibrations caused by operation of the first electric machine unit and second vibrations caused by operation of the second electric machine unit; and
operating the first electric machine unit and the second electric machine unit in dependence on at least one of characteristic data or a machine-learned unit,
wherein the at least one of the characteristic data or the machine-learned unit is configured to determine, in dependence on the first torque and the second torque, control instructions for the first electric machine unit and for the second electric machine unit, operation of the first electric machine unit and of the second electric machine unit with the target vibrations being effected by the control instructions.
