Abstract
An upshift control method for a dual clutch transmission (DCT) for a vehicle includes: determining, by a controller, whether or not an inertia phase begins when a driver accelerator pedal depression amount increases during power-on upshifting; calculating, by the controller, a first control amount, which is a first final clutch torque for controlling an engaging clutch, when the inner phase begins, in consideration of a difference between a current accelerator pedal depression amount and an accelerator pedal depression amount at beginning of the inertia phase, a difference between the current accelerator pedal depression amount and a maximum value of an accelerator pedal depression amount during the inertia phase elapsed until a present time, and a target engine torque, and controlling, by the controller, the engaging clutch with the final clutch torque calculated in the calculating.
