<p>The invention essentially relates to a method for upshifting gear ratio under torque in a dual clutch transmission (DCT) gearbox (1), comprising the following steps: controlling the output clutch (2.1, 2.2) and the input clutch (2.1, 2.2), respectively, such that the torque transmitted by the output clutch decreases and the torque transmitted by the input clutch increases; completely opening the output clutch (2.1, 2.2); freezing the torque instruction of the input clutch (2.1, 2.2); and controlling the input member (2.1, 2.2) in order to ensure the synchronization of the engine speed with the speed of the main input shaft, characterized in that the step of opening the output clutch (2.1, 2.2) is carried out at the moment a change in the indicia of the torque transmitted by the output clutch is detected.</p> |
