Abstract
본 발명은 가변 대역 노크 제어 회로에 관한 것으로, 증폭기로부터 출력되는 노크 신호와 제어 신호를 입력받아, 상기 제어 신호에 의해 결정되는 가변 주파수대의 신호를 필터링함으로써, 변화하는 노크 신호 중 가장 큰 노크 신호를 선택하여 출력하는 가변 대역 필터와, 상기 노크 신호를 감지하고 제어하면 감지된 노크 신호를 디지탈 신호로 변환시켜 이에 해당하는 제어 신호를 상기 가변 대역 필터로 출력하는 마이컴부를 포함하여 구성되어 있으며, 가변 대역 필터를 이용하여 차량 엔진의 실린더에서 발생되는 노크 신호를 정확하게 감지하고 제어할 수 있도록 한 가변 대역 노크 제어 회로에 관한 것이다.The present invention relates to a variable band knock control circuit, which receives a knock signal and a control signal output from an amplifier and filters a signal of a variable frequency band determined by the control signal, thereby receiving the largest knock signal among the changed knock signals. And a variable band filter for selecting and outputting a variable band filter, and a microcomputer unit for converting the detected knock signal into a digital signal when the knock signal is detected and controlled, and outputting a corresponding control signal to the variable band filter. The present invention relates to a variable band knock control circuit that enables a filter to accurately detect and control a knock signal generated from a cylinder of a vehicle engine.
