<P>PROBLEM TO BE SOLVED: To provide an operating method distinguished in particular by increased comfort when an internal combustion engine is connected into a drive train. <P>SOLUTION: The method for operating the drive train 1 provided with the internal combustion engine 2, an electric motor 10, a transmission 11, and a first clutch 12 connecting the internal combustion engine 2 to the electric motor 10 is provided, wherein during an operation mode for applying a current requested torque to a transmission input part 15 in such a state that the electric motor 10 is ON and the internal combustion engine 2 is OFF, the internal combustion engine 2 is connected to the power train by ; increasing a torque applied from the electric motor 10 to the drive train 1 before the internal combustion engine 2 starts such that only the current requested torque is applied to the transmission input part 15; extracting excess torque from the drive train 1 by actuating the first clutch 12 and applying the excess torque to the internal combustion engine 2 to accelerate the internal combustion engine 2; and starting the internal combustion engine 2 when a starting state is reached. <P>COPYRIGHT: (C)2008,JPO&INPIT |
