Abstract:
A drive device for a vehicle having a combustion engine and a multistage manual transmission having first and second sub-transmissions, each of which has a separate input shaft. A first input shaft of the first sub-transmission couples, via a first clutch, the combustion engine or is assigned an electrical machine. A second input shaft of a second sub-transmission couples, via a second clutch, the combustion engine. The first input shaft is additionally assigned a start-up element having at least one hydrodynamic transfer element, which has first and second functional wheels which together form a working chamber. The working chamber can be filled with fluid in order to generate a hydrodynamic transfer torque such that at least one start-up function, affecting the first sub-transmission, can carried out by way of the start-up element.
