Abstract
A shift control method for a hybrid vehicle having a dual clutch transmission may include an undershoot determination step of determining, by a controller, whether the amount of undershoot occurring during an inertia phase of power-off upshift is equal to or greater than a prescribed reference amount, a response-starting step of starting, by the controller, when the amount of undershoot is equal to or greater than the prescribed reference amount, coordinated engine torque control using a first coordinated torque, which is determined as the larger one of engine model torque determined from a model and engine map torque obtained from a map in a response to clutch slippage, and a response-maintaining step of determining, by the controller, second coordinated torque to control the engine and controlling engine torque until the inertia phase is completed.
