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 drive train of a motor vehicle. The method comprises the following steps: preparing a sample; the first driving unit provides first driving power and transmits the first driving power to the output device through the first friction clutch and the first sub-transmission; wherein a first internal combustion engine gear is shifted in the firstsub-transmission, while a second drive unit provides a second drive power to the output via the second sub-transmission, the second friction clutch is disengaged and a first motor gear lower than thefirst internal combustion engine gear is shifted in the second sub-transmission; determining whether to shift from a first motor gear to a higher second motor gear in a second sub-transmission, if yes, the first sub-transmission shifts from the first internal combustion engine gear to a second internal combustion engine gear higher than the first internal combustion engine gear; and the driving power of the second driving unit is transmitted to the output device through the second friction clutch, the first friction clutch and the first sub-transmission, and the second sub-transmission is switched to a 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 ...
