Abstract
The present invention relates to a drivetrain having a first clutch, which has an input side and an output side which is selectively connectable in terms of rotational drive to the input side, and having a transmission, which has a transmission shaft which is connected or connectable in terms of rotational drive to the output side and which is selectively connectable in terms of rotational drive to a gearwheel by means of a second clutch, wherein a rotor of an electric machine is arranged on the output side, and the electric machine, in motor operation, can be controlled or regulated so as to cause the rotational speeds of the transmission shaft and of the gearwheel to be approximated to or aligned with one another before the closure of the second clutch. The present invention also relates to a method for performing gearshifts in a transmission within a drivetrain of the type according to the invention.
