摘要：For enhancing the operational safety of an electric drive unit of a vehiclecomprising a generator, which is operated by a combustion machine, and drive motors,which are connected to said generator via a direct-voltage intermediate circuit, thegenerator and drive motors are each subdivided into partial units, and these partial units
have partial power electronics units associated therewith. The mutually correspondingpartial units of generator, motors and power electronics units each constitute a drivecircuit of their own, with control signals being supplied to components thereof by aspecifically assigned system control unit. The system control units that areinterconnected via an information exchange channel can undertake compensationmeasures in their drive circuit or in the other drive circuits in the event of a complete orpartial failure of a drive circuit. As an alter-native to the assignment of one systemcontrol unit at a time to a drive circuit, here may also be several system control unitsconnected to the individual drive circuits via bus connections or via multiple singlechannels.
