摘要： The invention relates to a method for controlling a shifting-up process (e.g. 4-6) in a double-clutch transmission (10) which has a double-clutch transmission input shaft (12) which is connected to a drive engine (14), two friction clutches (16, 18) and two component transmissions (20, 22), having the steps: - sensing of a shifting request from a low source gearspeed (4) into a higher target gearspeed (6), wherein the source gearspeed and the target gearspeed are assigned to one (22) of the two component transmissions (20, 22) of the double-clutch transmission (10), - opening of the friction clutch (18) which is assigned to the one component transmission (22), and closing of the friction clutch (16) which is assigned to the other component transmission (20), in order to transmit, without a dip in the tractive force, driving power via an intermediate gearspeed (5) of the other component transmission (20), wherein, as a result, the rotational speed of the double-clutch transmission input shaft (12) is lowered, - disengagement of the source gearspeed (4) and intermediate pressing on the friction clutch (18), assigned to the one component transmission (22), before the target gearspeed (6) is engaged, wherein the rotational speed of the one component transmission (22) is reduced by the pressing operation by virtue of the fact that the double-clutch transmission input shaft (12) which rotates at a reduced rotational speed transmits a drag torque (58) to the one component transmission (22), with the result that it is possible to start synchronization of the target gearspeed (6) at a reduced differential rotational speed (w), and - opening of the friction clutch (16) which is assigned to the other component transmission (20), and closing of the friction clutch (18) which is assigned to the one component transmission (22), in order to transfer driving power to the target gearspeed (6) without a dip in tractive force.
