Abstract
A control method using a continuous variable duration apparatus provided to adjust opening duration of an intake valve of an engine may include: setting a desired deceleration speed when a vehicle starts decelerating, determining a pumping loss by the engine that is required for the desired deceleration speed, setting desired duration for the required pumping loss by the engine, and controlling duration of the intake valve on the basis of the set desired duration.
