Abstract
A method of controlling a hybrid drive-train of a vehicle having a combustion engine with a driveshaft, a transmission with an input shaft and an output shaft that drives a transfer box. An electric machine has a rotor that is connected to the transmission input shaft. A separator clutch is arranged between the engine driveshaft and the transmission input shaft. For coupling of the engine, the engine is first accelerated, with a rotational speed regulation, toward a target speed until a reference speed is reached or exceeded while the clutch remains disengaged, then, with continuous speed regulation, the engine is adjusted to a corrected target speed while the clutch is engaged until a target torque is obtained, then, with torque control, the engine is adjusted to the target torque while the clutch, with differential rotational speed regulation, is regulated to a target speed difference, and finally the clutch is engaged.
