Patent ID: 8444528

Claim:
A method for operating a drivetrain of a motor vehicle, the drivetrain comprising a transmission arranged between a drive assembly and an axle drive, such that an input shaft of the transmission being connected, via a controllable separator clutch, to the drive assembly and an output shaft of the transmission being connected to the axle drive, and the transmission comprises at least one shifting element formed as a claw clutch, the method comprising the steps of: to reduce a probability that a tooth-on-tooth position may occur in a shifting element formed as a claw clutch, an initial torque is applied thereto by at least one of a transmission-internal assembly and a transmission-external assembly, such that a speed difference at the claw clutch approaches a predetermined nominal value, commencing engagement of the claw clutch only when a speed difference of the claw clutch reaches the nominal value; and applying a reduced torque to the claw clutch, during engagement of the claw clutch before a tooth-on-tooth position occurs, by at least one of the transmission-internal assembly and the transmission-external assembly, and the reduced torque being less than the initial torque but at least as great as a friction torque of a tooth-on-tooth position that may form during engagement of the claw clutch.
