  • Patent number: 10286773
    Abstract: A device includes a transmission and an electric machine for a hybrid drive of a motor vehicle, and the transmission includes first and second subtransmissions. The substransmissions each have an input shaft and they share an output shaft. The input shafts of the subtransmissions can be selectively coupled to the output shaft via form locking clutches of the subtransmissions. In particular, a first input shaft of the first subtransmission is allocated to a first friction locking clutch while a second input shaft of a second subtransmission is allocated to a second friction locking clutch. Furthermore, a third clutch is incorporated between an input drive side clutch half of the first friction locking clutch and an input drive side clutch half of the second friction locking clutch.

  • Patent number: 10099684
    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.
