Abstract
이 발명은 자동차의 엔진소음의 일종인 부밍 노이즈(Booming)를 제거하기 위한 능동소음 제거장치(Active Noise Control system) 및 그 제어방법에 관한 것으로서, 기준신호의 주파수에 대응하여 미리 매핑되어 있는 위상값을 저장하는 메모리와; 운전자의 조작에 따라 진폭갑이 결정되도록 하는 튜너와 기준 신로를 받아들이고, 상기 메모리로부터 기준신호의 주파수에 대응하는 위상갑을 페취하고, 상기 튜너에서 결정된 진폭값을 입력 하며, 상기 기준신호의 주파수, 상기 폐취된 위상 및 입력된 진폭으로 구성되는 사인파형을 상쇄파형으로서 생성하여 출력하는 제오기와; 상기 제어기이서 출력되는 사인파형에 따라 구동되는 스피커로 구성되어, 간단하게 부밍노이즈를 제거할 수 있으며, 적은 비용으로 능동소음 제거장치를 구성할 수 있을 뿐만 아니라 계산량이 적기 때문에 급가속시의 부밍 노이즈도 효과적으로 제거할 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an active noise control system for removing booming noise, which is a kind of engine noise of an automobile, and a control method thereof, wherein a phase value previously mapped to a frequency of a reference signal is pre-mapped. A memory for storing; Accepts a tuner and a reference path for determining the amplitude value according to the driver's operation, fetches the phase value corresponding to the frequency of the reference signal from the memory, inputs the amplitude value determined by the tuner, and the frequency of the reference signal. A squirrel generating and outputting a sinusoidal waveform composed of the closed phase and the input amplitude as an offset waveform; It is composed of a speaker driven according to the sine wave output from the controller, it is possible to simply remove the booming noise, and to configure the active noise canceling device at a low cost, as well as a small amount of calculation booming noise during rapid acceleration Can be effectively removed.
