Abstract
A method for controlling and regulating a power train of a hybrid vehicle and a power train of a hybrid vehicle having one internal combustion engine, one electric machine, one shifting element and one output in a power flow of the power train and designed with continuously variable transmitting capacity and one clutch device and the internal combustion engine. The electric machine can be operatively interconnected via the clutch device, the hybrid vehicle being optionally driveable via the electric machine and/or via the internal combustion engine and the internal combustion engine can be started via the electric machine. In the operation of the power train, the transmitting capacity of the shifting element during the starting operation of the internal combustion engine is adjusted so that on the output of the power train, a torque abuts which is independent of the starting operation of the internal combustion engine.

- 19. A method for controlling and regulating a power train (1) of a hybrid vehicle having one internal combustion engine (2), one electric machine (3), one shifting element disposed in a power flow of the power train (1) between the electric machine (3) and an output (5) and designed with continuously variable transmitting capacity and one clutch device (7), located between the electric machine (3) and the internal combustion engine (2), which can bring to operative connection the electric machine (3) and the internal combustion engine (2), the hybrid vehicle can optionally be driven via one of more of the electric machine (3) and the internal combustion engine (2), the internal combustion engine (2) can be started by means of the electric machine (3) by creating the operative connection between the electric machine (3) and the internal combustion engine (2) via the clutch device (7), in the operation of the power train (1) the transmitting capacity of a shifting element (11) is adjusted during a starting operation of the internal combustion engine (2) so that a torque independent of the starting operation of the internal combustion engine (2) abuts on an output of the power train (1).
- 31. A power train (1) of a hybrid vehicle having one internal combustion engine (2), one electric machine (3), one shifting element (11) situated between the electric machine (3) and one output (5) in a power flow of the power train (1) and designed with continuously variable transmitting capacity, and one clutch device (7) situated between the electric machine (3) and the internal combustion engine (2) by which the electric machine (3) and the internal combustion engine (2) can be brought to operative connection wherein the hybrid vehicle can optionally be driven via one or more of the electric machine (3) and the internal combustion engine (2), the internal combustion engine (2) can be started by means of the electric machine (3) by creating a connection between the electrical machine (3) and the internal combustion engine (2) via the clutch device (7), between the internal combustion engine (2) and the electric machine (3) one device (6) is provided for dampening rotational irregularities and is at least partly integrated in a housing of the transmission (4).
