Abstract
A method of controlling a drive-train of a motor vehicle, which comprises an internal combustion engine with a driveshaft, an electric machine in driving connection with the driveshaft of the internal combustion engine, a semi-automatic transmission with an input shaft and a plurality of gears that can be engaged selectively, and an automated friction clutch arranged between the driveshaft of the internal combustion engine and the input shaft of the transmission, such that a gearshift of the transmission occurs in combination with suitable control of the internal combustion engine while the friction clutch is at least partially and/or briefly engaged. To speed up the shifting process and to attenuate torque and speed surges during the shifting process, the electric machine is operated briefly as a generator and/or as a motor.
