Abstract
본 발명은 자기 상관 기법에 의한 노크신호의 추정방법 및 그 장치에 관한 것으로서, 자동차 엔진에 발생하는 노킹을 감지하여, 그에 따른 전기적인 신호를 출력하는 노킹 감지부(10)와, 상기 노킹 감지부(10)로부터 출력되는 신호를 입력받아, 필터링을 하여 잡음을 제거하는 대역통과필터(Band Pass Filter, 20)와, 상기 대역통과필터(20)로부터 출력되는 신호를 입력받아, 디지탈 신호로 변환하여 출력하는 아날로그-디지탈 변환기(30)와, 상기 아날로그-디지탈 변환기(30)로부터 출력되는 신호를 입력받아, 노킹 상태의 추정값을 생성하여 출력함으로써, 노킹 제어를 할 수 있도록 하는 노킹 추정부(40)와, 상기 노킹 추정부(40)로부터 출력되는 신호를 입력받아 그에 따라 해당하는 노킹을 제어하는 노킹 제어장치(50)로 이루어져 있으며, 자동차 엔진의 노킹이 발생할 경우, 발생하는 노킹을 제어하는 데에 있어서, 자기 상관 기법에 의하여, 노킹의 정도를 추정하여 제어하도록 하는, 자기 상관 기법에 의한 노크신호의 추정방법 및 그 장치에 관한 것이다.The present invention relates to a knock signal estimating method and apparatus therefor by autocorrelation, and includes a knocking sensing unit 10 for detecting knocking occurring in an automobile engine and outputting an electrical signal according to the knocking sensing unit. A band pass filter 20 which receives a signal output from the signal 10, filters the noise, and receives a signal output from the band pass filter 20, converts the signal into a digital signal. A knock estimator 40 for receiving the analog-digital converter 30 to output and a signal output from the analog-digital converter 30, generating an estimated value of the knocking state, and outputting the estimated value. And a knocking control device 50 which receives a signal output from the knocking estimating unit 40 and controls a corresponding knocking accordingly, and knocking of an automobile engine occurs. In this case, the present invention relates to a method and apparatus for estimating a knock signal by an autocorrelation technique for controlling knocking generated by estimating the degree of knocking by an autocorrelation technique.
