Abstract
An intake system mounted to a vehicle controls an opening angle of a variable flap according to an RPM of an engine, an intake pressure, and an opening angle of a variable flap to optimize performance in various operation regions by detecting engine RPM and an intake air pressure, and determining an operation region based on the RPM of the engine; applying the intake pressure to determine a target amount of air and an opening angle of a variable flap for an operation region; driving an actuator to adjust an opening angle of the variable flap to a target opening angle; and analyzing an operation position of the actuator to detect an opening angle of the variable flap, and, when the target opening angle is not followed, correcting a drive of the actuator such that an opening angle of the variable flap follows the target opening angle.
