    • The invention relates to a method for operating a drive device (1) of a motor vehicle, said drive device (1) comprising at least one combustion engine (3) and at least one electric machine (9), as well as a dual clutch transmission (4) which can be functionally connected to the combustion engine (3) and which comprises a first sub-transmission (5), a first clutch (6) being associated therewith, and a second sub-transmission (7), a second clutch (8) and the electric machine (9) being associated therewith. In a purely electrical driving operation, the electric machine (9) is operated in a motorized manner, a driving gear is engaged in the second sub-transmission (7), and both clutches (6, 8) are disengaged. According to the invention, in order to start the combustion engine (3) during the electric driving operation, the second clutch (8) is engaged so as to drive the combustion engine (3) by means of the electric machine (9), a gear is engaged in the first sub-transmission (5), said gear having a lower gear ratio than the engaged driving gear of the second sub-transmission (7), the first clutch (6) is brought into a slip position and the second sub-transmission (7) is subsequently brought into a neutral position, the rotational speed of the electric machine (9) is increased at least to a starting rotational speed for the combustion engine (3) with the slip of the first clutch (6) being adjusted to maintain a forward torque of the motor vehicle, and the combustion engine (3) is started once its starting rotational speed has been reached. In addition, the invention relates to a device for operating a drive device of a motor vehicle.
    • 本发明涉及一种用于操作机动车辆的驱动装置(1)的方法,所述驱动装置(1)包括至少一个内燃机(3)和至少一个电机(9),以及双离合器 变速器(4),其能够在功能上连接到内燃机(3)并且包括第一副变速器(5),与其相关联的第一离合器(6)和第二副变速器(7),第二副变速器 离合器(8)和与其相关联的电机(9)。 在纯电动驾驶操作中,电机(9)以电动方式操作,驱动齿轮接合在第二副变速器(7)中,并且两个离合器(6,8)脱离。 根据本发明,为了在电驱动动作期间启动内燃机(3),第二离合器(8)接合以便通过电机(9)驱动内燃机(3), 齿轮接合在第一副变速器(5)中,所述齿轮具有比第二副变速器(7)的接合驱动齿轮低的齿轮比,第一离合器(6)进入滑动位置,第二离合器 副变速器(7)随后进入中立位置,电动机(9)的转速随着第一离合器(6)的滑动而增加至内燃机(3)的起动转速, 被调整为保持机动车辆的前转矩,并且一旦达到起动转速就起动内燃机(3)。 此外,本发明涉及一种用于操作机动车辆的驱动装置的装置。
