Shift control method for hybrid vehicle having dual clutch transmission

A shift control method for a vehicle having a dual clutch transmission, the shift control method comprising:

• undershoot determination operation of determining, by a controller, when an amount of undershoot occurring during an inertia phase of power-off upshift is equal to or greater than a predetermined reference amount;
• response-starting operation of starting, by the controller, in a response that the amount of the undershoot is equal to or greater than the predetermined reference amount, coordinated engine torque control using a first coordinated torque, which is determined as a 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
• response-maintaining operation of determining, by the controller, a second coordinated torque to control an engine and controlling an engine torque until the inertia phase of the power-off upshift is completed.
