The invention relates to a non-railbound land vehicle () comprising a drive system with the following components; a combustion engine-generator unit (=VG unit) (); at least one electric drive motor (); a power control station () for the electric motor that can be operated by the driver of the vehicle and a control electronics () that is connected to the VG unit, the electric motor and the power control station. The invention is characterized in that the control electronics is configured and can operate in such a way that it reduces temporarily the electrical power demanded by the electric motor and/or at least one secondary current consumer for the transition from one operating phase with a first power state of the electric motor and/or at least one secondary current consumer () of the vehicle to an operating phase with a higher, second power state of the electric motor and/or at least one secondary current consumer in order to attain fster transition of the combustion engine () from a first power output to a higher second power output.

Method for operating a non-railbound land vehicle with a combustion engine-generator unit and an electric drive motor and corresponding vehicle

For enhancing the operational safety of an electric drive unit of a vehicle comprising a generator, which is operated by a combustion machine, and drive motors, which are connected to said generator via a direct-voltage intermediate circuit, the generator and drive motors are each subdivided into partial units, and these partial units have partial power electronics units associated therewith. The mutually corresponding partial units of generator, motors and power electronics units each constitute a drive circuit of their own, with control signals being supplied to components thereof by a specifically assigned system control unit. The system control units that are interconnected via an information exchange channel can undertake compensation measures in their drive circuit or in the other drive circuits in the event of a complete or partial failure of a drive circuit. As an alter-native to the assignment of one system control unit at a time to a drive circuit, here may also be several system control units connected to the individual drive circuits via bus connections or via multiple single channels.

Electric drive system, especially for vehicles

For obtaining a compact superconductive power switch for rapid switching speeds and with high dielectric strength, several winding layers ( ) with several windings each are lined up adjacent each other in axial direction. Between individual layers ( ), there are provided cooling/heating elements ( to ) in order to transfer the high-current switch unit ( ) to the superconducting state and the normally conducting state, respectively, by cooling/heating, i.e. for closing and opening said unit, respectively. Mutually adjacent current conductors have the switching current flowing therethrough in opposite directions, so that the high-current switch unit ( ) is of low induction, which permits fast switching times in particular when the switch is opened by an additional current pulse. Due to the numerous windings of the current conductor sections in each layer and the plurality of layers in axial directions, only a low voltage differential results between the adjacent current conductors, and an assembly with high dielectric strength is obtained in total.
