Abstract
본 발명은 노이즈가 입력되지 않도록 정류 방식을 달리하여 정확한 노크값을 검출하여 노킹상태에 해당하는 점화시기를 안전하게 찾는 효율적인 제어가 이루어지도록 한다. 노크센서(1)로부터 입력받은 신호를 인지가 가능하도록 증폭하는 증폭(2)부와; 상기 증폭(2)부로부터 증폭된 신호를 입력받아 특정 범위 즉 노크 신호에 대한 주파수를 통과시키기 위한 필터(3) 처리부와; 상기 필터(3) 처리부로부터 필터된 신호를 입력받아 노이즈를 검쇄하는 고정 전압이 설정되어 정류되는 정류(4) 처리부와; 상기 정류(4) 처리부로부터 정류된 신호로 적분하는 적분(5) 처리부로 이루어져 있는 자동차의 노크 검출장치인 것이다.The present invention allows the efficient control to find the ignition timing corresponding to the knocking state by detecting the correct knock value by changing the rectification scheme so that noise is not input. An amplification unit 2 for amplifying a signal received from the knock sensor 1 so as to be recognized; A filter (3) processing unit for receiving the amplified signal from the amplifying unit (2) and passing a frequency for a specific range, that is, a knock signal; A rectifying (4) processing unit for receiving a filtered signal from the filter (3) processing unit and setting and rectifying a fixed voltage for detecting noise; It is a knock detection device for a motor vehicle comprising an integration (5) processing unit for integrating the signal rectified from the rectification (4) processing unit.
