The disclosure relates to a method for controlling a powertrain of an electric vehicle. The method comprises receiving a torque demand signal (S1). 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 (S2). Alternatively or additionally the loss can be estimated as a function of a free rolling state of at least one of the electric machines (S2). 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 (S3). 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 comprises such a data processing device and at least two electric traction machines and/or a clutch device.
