A method for controlling a powertrain of an electric vehicle. The method includes receiving a torque demand signal. Thereafter, a future power loss within the powertrain is estimated as a function of a torque distribution between at least two electric traction machines of the powertrain. Alternatively or additionally the loss can be estimated as a function of a free rolling state of at least one of the electric machines. Subsequently, a torque distribution between the electric traction machines is determined and/or a free rolling state of at least one of the electric machines is determined which minimizes the future power loss. Moreover, a corresponding data processing device, a corresponding computer program and a corresponding computer-readable medium are presented. Moreover, a powertrain for an electric vehicle is described. The powertrain includes such a data processing device and at least two electric traction machines and/or a clutch device.
