Antriebssystem für ein Kraftfahrzeug

Source: WO15028147A1 [EN] The invention relates to a method for driving a motor vehicle and a drive system for a motor vehicle, for the solely electro-motorized forward movement of which at least one electric motor is directly or indirectly connected to a drive shaft of the motor vehicle, which electric motor is supplied with electrical energy via an energy storage unit, which energy is supplied with electrical charge current by a generator, which generator is driven by a gas engine. The invention is characterized in that the gas engine is operated during forward movement of the motor vehicle such that an average power demand, which can be allocated to the electric motor, equals an average power output, which can be allocated to the gas engine, such that a charge state, which can be allocated to the energy storage unit, does not change or changes solely within a charge state range subject to tolerances.
