Abstract
A method for controlling a supercharger of a vehicle includes: determining, at a first determination step, whether or not an engine operates in a cylinder deactivation (CDA) mode; calculating, at a second determination step, a difference value between a target boost pressure of a turbocharger and a current boost pressure of intake air boosted by the turbocharger, and determining whether or not the difference value is equal to or greater than a reference difference value; determining, at a third determination step, based on a current operating condition of the engine whether or not the supercharger is allowed to operate; determining, at a fourth determination step, a target rpm of the supercharger, and determining whether or not the target rpm is equal to or greater than a reference rpm; and operating the supercharger at an operating step.
