Abstract
A hybrid driving system for a vehicle including a generator connected to an internal combustion engine () which is linked to an electric driving motor () by means of a generator frequency converter, an intermediate voltage circuit and a motor frequency converter. An energy-storage reservoir () is connected to the intermediate voltage circuit. The intermediate voltage circuit is divisible into two partial intermediate circuits () by means of a first switch (). Each partial intermediate circuit includes at least one driving motor () connected by means of the corresponding motor frequency converter. For the purpose of adjusting the hybrid driving system, when the voltage (U) in the energy storage reservoir () is lower than the voltage of the corresponding intermediate voltage circuit, the first switch () arranged between two intermediate circuits () switches off the link and the first switch () becomes an open conductor only.
