The transmission (2) further includes a second sub-transmission (6) including a second input shaft (8), the second sub-transmission (6) being a planetary transmission (PG) with a sun gear (24), a ring gear (22), and a carrier (23).

The present invention relates to a hybrid driving module, in which an input member is aligned in a radial direction and/or an axial direction by a rotor hub, and thus the hybrid driving module may be easily assembled and ensure the high axial balance and the operability and durability of the engine clutch. In the hybrid driving module, the input member may be aligned at least in the radial direction or in the axial direction by a central shaft extension part of the rotor hub. A bearing configured to support a rotation and thrust may be installed between the central shaft extension part and the input member. The input member may be supported to be rotatable relative to a housing. The input member may be aligned in the radial direction and/or the axial direction by the housing.

The present invention provides a hybrid driving module which fixes a rotor while hub ridges of the rotor are provided on a rotor hub and firmly provides the hub ridge to the rotor hub so as to enable vibration noise to be reduced, and which has a structure in which the hub ridges support the rotor in a state in which the hub ridges are fastened to the rotor hub at which the rotor is provided. The hybrid driving module may further include a ridge fixing structure that prevents the hub ridge from separating from the rotor hub. For example, the ridge fixing structure may be a ridge snap ring. The hybrid driving module may further include an elastic body that elastically presses the hub ridge toward the ridge snap ring. The elastic body may elastically press the rotor in the axial direction. The elastic body may also serve as a return spring of the piston plate of the engine clutch.

A method for controlling a powertrain of a hybrid vehicle includes the following steps performed by a hybrid controller: determining whether an ambient air temperature is lower than a predetermined temperature; driving a motor and operating a heating disc of an electrically heated catalytic converter disposed in an exhaust pipe of an internal combustion engine during a predetermined operating time when an ambient air temperature is lower than a predetermined temperature; supplying ambient air to the heating disc; and varying a flow rate of the ambient air supplied to the heating disc in response to a temperature change of the heating disc.

A method for operating a hybrid drive assembly for a motor vehicle, which has an internal combustion engine and an electric engine. A separating clutch arranged in drive terms between the internal combustion engine and the electric engine is set to a target clutch torque by at least partially engaging during an attempt to start the internal combustion engine. An actual clutch torque actually transmitted via the separating clutch and a speed of the internal combustion engine are determined during the attempt to start, and if a characteristic value dependent on the actual clutch torque exceeds a threshold value and if an integral of the speed over time continuously falls below a limit value during the attempt to start, the attempt to start is aborted.
