Abstract: A drive train for a motor vehicle comprises an internal combustion engine which has a crankshaft and is designed to provide drive power for the motor vehicle. A clutch arrangement has an input member and at least one output member, the input member being connected to the crankshaft. A transmission arrangement implements a plurality of gear stages, the transmission arrangement having a transmission housing, at least one input shaft, and at least one output shaft. The output shaft is connectable to driven wheels of the motor vehicle. An electric machine is designed to provide drive power for the motor vehicle and is connected to a transmission shaft of the transmission arrangement. The transmission shaft has a shaft section which extends from the transmission housing and is connected to the electric machine via a traction drive mechanism.

Abstract: Method for controlling a hybrid drivetrain which has a drive engine and a dual-clutch gearbox which, to establish two power transmission paths, has a first and a second friction clutch and a first and a second component gearbox. An electric machine is connected to the second power transmission path downstream of the second friction clutch in the power flow direction. Purely electric driving operation can be realized by means of the second component gearbox assigned to the second friction clutch. In the event of a gear change in the second component gearbox during purely electric driving operation, a fill-in torque is provided. The fill-in torque is provided from inertial energy of the previously cranked, non-fired drive engine, wherein the drivetrain also has an electric starter motor, and wherein the starter motor is used to crank the drive engine.
