illustrated in detail in fig1 such as a combustion engine or the like moreover the drive train 12 can in this case be a gear mechanism and similar the electric induction machine 14 is embodied in a multi phase manner in the present case with three phases and is controlled by means of an electronic power system 18 the electronic power system 18 is connected to an energy supply such as a dc voltage supply e g rechargeable battery 20 of the vehicle 10 and is used for the purpose of converting dc voltage that is provided by the rechargeable battery 20 into three ac currents for the three phases of the electric induction machine the electronic power system 18 comprises for this purpose a plurality of power switches and is controlled by means of a control device 22 the control device 22 can moreover be connected to the electric induction machine 14 in order to obtain by way of example actual values of the rotation speed and or the angular position of a rotor of the electric induction machine 14 moreover the control device 22 can be connected to the rechargeable battery 20 finally the control device 22 can be connected to a higher priority or equal priority control device 24 for the purpose of.
