Patent ID: 8398527

Claim:
A method of controlling a dual-clutch transmission in a motor vehicle, including two partial drivetrains, each having a plurality of gears, which each can be connected to a crankshaft of an internal combustion engine by means of a friction clutch, the method comprising the following steps: the first friction clutch transmits a first torque to the first partial drivetrain assigned to it; the second friction clutch transmits a second torque to the second partial drivetrain; and, the two partial drivetrains have a common differential, wherein when there are changes in torque and the amount of torque to be transmitted is low, and there is downshifting into a gear with a high transmission ratio in the first partial drivetrain, downshifting occurs into a gear with a low transmission ratio in the second partial drivetrain, and a preliminary torque is applied to the differential by this gear.
