The invention relates to a method for operating a hybrid dual clutch transmission of a drive train having an internal combustion engine, a dual clutch device, a first and a second sub-transmission, and an electric machine which is connected to or can be connected to an input of the second sub-transmission, in the power-assisted operation of the hybrid power, the drive power of the electric machineis first transmitted via the second sub-transmission, the friction clutch associated with the second sub-transmission is disconnected and engaged with the gear 2, the drive power of the internal combustion engine is transmitted via the first sub-transmission, the friction clutch arranged in the sub-transmission is closed and engaged with the gear 3, and the gear 2 is engaged with the gear 3. Whencontinuing to accelerate, the method comprises shifting the electric machine into a first sub-transmission in a drive-effective manner, operating the two drive machines in a gear position 3 via the first sub-transmission until a limit rotational speed of the internal combustion engine is about to be reached, shifting the electric machine to a gear position 4, and shifting the internal combustionengine from the gear position 3 to the gear position 4 in a small time interval for this purpose.
