A method and control means for operating a drivetrain

Method for operating a drivetrain of a motor vehicle, wherein the drive train comprises a drive unit (1), a transmission (5) and an output (4), for starting a frictional shift element (10) of the gearbox (5) is such a slipping concluded that during the closing operation of the slip at which serves as a starting element frictional shift element (10) a defined pressure-driving the switching element (10) is reduced, which serves during the closing operation of the starting element frictional shift element (10), the differential speed on serving as a starting element frictional switching element (10) or a dependent of the differential rotational speed value is determined, and wherein when the differential speed or dependent on the rotational speed difference value is smaller than a first threshold value or reaches the first threshold value, the rotational speed of the drive unit (1) is changed so that within a d efinierten period, the differential speed, or dependent on the rotational speed difference becomes smaller size than a second threshold value or reaches the second limit value, wherein the second threshold is smaller than the first threshold.
