Abstract

A method is provided for operating a drive unit for a hybrid vehicle. Through a planetary transmission, an electric motor is coupled to an input shaft of a first sub-transmission and an input shaft of a second sub-transmission shifted in parallel to the first sub-transmission. Through a frictional-locking separating clutch, an internal combustion engine is able to be coupled to the input shaft of the first sub-transmission and, if the separating clutch is locked, is coupled to the same element of the planetary transmission together with the input shaft of the first sub-transmission. For coupling the internal combustion engine at the output coming out of all-electric driving, the torque provided by the internal combustion engine is transferred through the slip-controlled separating clutch in order to unload the previously locked shift element and disengage it in the unloaded state.

Description

technical field

[0001] The invention relates to a method for operating a drive unit for a hybrid vehicle. Background technique

[0002] A drive unit for a hybrid vehicle is known from DE 10 2006 059 591 A1, wherein the drive unit comprises a drive unit with an internal combustion engine and an electric machine and a transmission connected between the drive unit and an output. The transmission is designed as a dual clutch transmission and includes a plurality of sub-transmissions. The electric machine of the drive unit of the drive unit is coupled via a planetary gear to an input shaft of a first sub-transmission and an input shaft of a second sub-transmission parallel to the first sub-transmission. The internal combustion engine can be coupled via a friction-locking release clutch to the input shaft of the first sub-transmission and, with the release clutch engaged, the internal combustion engine can be coupled directly to the input shaft of one of the sub-transmissions.
