    摘要： A method for operating a hybrid vehicle drive-train having an engine, electric machine, transmission and a planetary gearset comprising ring, sun and carrier elements. A first planetary element is coupled to a transmission input shaft, a second planetary element is coupled to the electric machine, and a first clutch couples a third planetary element to the engine while a second clutch couples two of the three elements. When the second clutch is disengaged, the drive-train operates in a first mode while, when the second clutch is engaged, the drive-train operates in a second mode. When starting up or crawling, to change from first to second mode while maintaining traction force at the output, the second clutch engages to reduce the transmission capacity of the first clutch until slip occurs, then the engine speed is regulated, while synchronizing the second clutch, after which the second clutch engages without any load.

    摘要： 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.

    摘要： A motor vehicle transmission having main group and a range group that is connected downstream from the main group which has a planetary stage with transmission components. A first component couples an output shaft of the range group and a second component couples an output shaft of the main group. A third component can couple a housing and the first or the second components. For carrying out a range shift of the range group, which cannot be shifted under load, and to enable an arrangement of gear steps of the upstream main group, the drive output shaft passes axially through the planetary stage to the main group. The output shaft is a central shaft with which the input shaft of the main group can be connected in a rotationally fixed manner, and over which the output shaft of the main group is positioned as a coaxially extending hollow shaft.
