Embodiment Construction

[0056] exist figure 1 In the diagram, a hybrid drive train 10 for a schematically shown motor vehicle 11 is shown in schematic form. The hybrid powertrain 10 comprises a first drive unit 12 in the form of an internal combustion engine connected to a fuel tank 13 . Furthermore, the hybrid drive train has a dual clutch transmission 14 . The drive power of the first drive unit 12 can be transmitted via the dual clutch transmission 14 to an output in the form of a differential 16 . The differential 16 serves to distribute the drive power to driven wheels 18L, 18R of the motor vehicle 11 .

[0057] The dual clutch transmission 14 has a first friction clutch 20 ( K1 ), the input member of which is coupled in rotation to the first drive unit 12 . The output member of the first friction clutch 20 is connected to the input of a first sub-transmission 22 ( TG1 ) comprising the odd forward gears of the dual clutch transmission. The first sub-transmission 22 has a plurality of shiftin...

Abstract

The invention relates to a method for operating a hybrid powertrain of a motor vehicle, comprising the steps of: providing a first drive power from a first drive unit and transmitting it towards an output device via a first friction clutch and a first sub-transmission, in the first sub-transmission Shifting to the first internal combustion engine gear, while the second drive unit supplies the second drive power to the output device via the second sub-transmission, the second friction clutch is disengaged and shifted to a lower than the first internal combustion engine gear in the second sub-transmission first motor gear; determine whether a shift from the first motor gear to a higher second motor gear is required in the second subtransmission, and if so, the first subtransmission shifts from the first internal combustion engine gear to a higher In the second internal combustion engine gear of the first internal combustion engine gear, the second sub-transmission is shifted to neutral and the driving power of the second drive unit is transmitted to the output device through the second friction clutch, the first friction clutch and the first sub-transmission, and the second The subtransmission shifts to the second motor gear.

Description

technical field [0001] The invention relates to a method for operating a hybrid drive train of a motor vehicle, wherein the hybrid drive train has a first drive unit, in particular in the form of an internal combustion engine, a second drive unit, in particular in the form of an electric machine, and a dual clutch transmission, wherein the The dual-clutch transmission has a first power transmission path and a second power transmission path, the first power transmission path has a first friction clutch and a first sub-transmission, and the second power transmission path has a second friction clutch and a second power transmission path. A sub-transmission wherein the first drive unit is coupled to the input member of the first friction clutch and the input member of the second friction clutch, and wherein the second drive unit is coupled to the output member of the second friction clutch. Background technique [0002] Such a drive train is known, for example, from document DE ...
