Abstract
A method for controlling a drivetrain in a motor vehicle which has an internal combustion engine with a crankshaft, an automated gearbox with engagable and disengagable gears and a gearbox input shaft and a gearbox output shaft which drives drive wheels, a friction clutch which connects the crankshaft and the gearbox input shaft in a separable manner and is operated in an automated fashion, and a control unit for controlling the drivetrain. For driving comfort, before the vehicle comes to a stop, a starting gear is engaged in an overrun mode such that, after opening the friction clutch, a synchronization of gearbox input and output shaft rotational speed of the starting gear is initiated at a gearbox input shaft rotational speed which is higher than a target rotational speed of the gearbox input shaft yielded by the transmission ratio of the starting gear between the gearbox input and output shaft.
