Abstract

본 발명은 차량 선루프의 풍절음 제어장치에 관한 것으로서, 선루프(R)에 설치되어 개방시 유입되는 공기와의 마찰로 발생하는 진동을 감지하는 진동감지센서(4)와; 선루프(R)와 공기의 마찰소음과 제어용 스피커(2)에서 발생하는 제어음의 합성으로 생기는 에러소음을 제어기로 피이드백시켜 제어의 오차를 저감시키는 마이크로폰(1)과; 진동감지센서(4)에서 제공되는 랜덤 신호를 디지탈 제어필터에 통과시켜 제어음을 발생시키고, 이 신호를 증폭용 앰프를 거쳐 스피커(2)로 인가시키며, 다시 에러소음 감지용 마이크로폰(1)에서 피이드백 되어지는 에러 소음으로 제어용 디지탈 필터의 계수들을 보정하여 소음의 제어를 안정화시키는 제어기(3)와; 제어기(3)에서 발생하는 제어신호를 실제로 발생시켜 소음을 제거하는 제어용 스피커(2)를 상호 연결시켜 선루프(R)의 개폐시 풍절음을 저감시킬 수 있도록 한 것으로 차량의 정숙성을 향상시킨 것이다.The present invention relates to a windshield control device for a vehicle sunroof, and more particularly, to a windshield control device for a vehicle sunroof, comprising: a vibration detection sensor (4) installed in a sunroof (R) for sensing vibration generated by friction with air introduced upon opening; A microphone 1 for reducing an error of control by feeding back the error noise generated by the friction noise of the sunroof R and the air and the control sounds generated by the control speaker 2 to the controller; A random signal provided from the vibration detection sensor 4 is passed through a digital control filter to generate a control sound and the signal is applied to the speaker 2 via an amplifier for amplification, A controller (3) for stabilizing control of noise by correcting coefficients of a control digital filter with feedback noise to be fed back; The control speaker 3 is connected to a control speaker 2 which actually generates a control signal to remove noise to reduce the wind noise during opening and closing of the sunroof R, thereby improving the quietness of the vehicle.
