Abstract
A vehicle powertrain has a first electrical machine with first power electronics and a second electrical machine with second power electronics. In symmetrical operation, the first and second electrical machines are loaded or operated with the same torque and with the same torque gradient. In a non-symmetrical operation, the first and second electrical machines are loaded or operated with a different torque and/or with a different torque gradient. If, after non-symmetrical operation the symmetrical operation is resumed, a subsequent modified operation can be used in which the electrical machine that was loaded or operated in non-symmetrical operation with higher torque and/or a higher torque gradient, is loaded or operated with a limited torque and/or with a limited torque gradient or is switched off or decoupled for a defined period of time, thereby at least partially compensating for a different aging of the electrical machines due to non-symmetrical operation.
