A coasting regeneration control method of a vehicle equipped with a continuously variable valve duration (CVVD) engine includes: determining, by an engine control unit (ECU), whether a current state of the vehicle satisfies coasting regeneration conditions; and entering, by the ECU, a coasting regeneration mode and performing regenerative braking when the current state of the vehicle satisfies the coasting regeneration conditions, in which when the coasting regeneration mode is entered, a throttle valve is fully opened so that the amount of intake air of the engine is maximized, a CVVD target duration is controlled to be maximized, and a closing time of an intake valve is delayed after a start point of time of a compression stroke, thereby decreasing pumping loss of the engine.
