  "textContent": "The method involves closing a coupling from an opened condition till coupling torque of the coupling exceeds drag torque of an internal combustion engine. The coupling is controlled with a torque gradient till rotational speed of the engine exceeds a resonance rotational speed of a two-mass-flywheel that is arranged between the coupling and an output shaft of the engine. The coupling is closed completely in such a manner that the rotational speed of the engine is matched with an input-sided rotational speed of a transmission in a skip-free manner.",
