摘要： The invention relates to a method for controlling a shift process in a dual-clutch gearbox having a dual-clutch gearbox input shaft connected to a drive engine, having two friction clutches and having two partial gearboxes. The method comprises the steps of detecting a demand for a shift from a source gear into a target gear, with the source gear and the target gear being assigned to one of the two partial gearboxes, opening the friction clutch which is assigned to the one partial gearbox and closing the friction clutch assigned to the other partial gearbox in order to transmit drive power via an intermediate gear of the other partial gearbox, disengaging the source gear and temporarily exerting pressure in the friction clutch assigned to the one partial gearbox before the engagement of the target gear, with the rotational speed of the one partial gearbox being reduced as a result of the pressure-exerting operation by virtue of a drag torque, opening the friction clutch assigned to the other partial gearbox and closing the friction clutch assigned to the one partial gearbox in order to transfer drive power to the target gear without an interruption in tractive force.
