Beschreibung
Zusammenfassung:	A powertrain includes a prime mover, a transmission, an input shaft adapted to transmit torque between the prime mover and the transmission, an output shaft adapted to transmit torque between the transmission and a driveline, and a master clutch between the prime mover and the input shaft, the clutch being movable between a disengaged position and an engaged position in which the clutch is not and is adapted to transmit torque between the prime mover and the input shaft, respectively. An electric motor is arranged for torque transmission with at least one of the input shaft and the output shaft, and a controller is provided for controlling the electric motor to rotate the input shaft at a rotational speed within an operating range of the prime mover when the clutch is moved from the disengaged to the engaged position.
