Abstract

본 발명은 차량의 노크(knock) 제어회로에 관한 것으로, 보다 상세하게는 차량엔진의 실린더에 발생되는 노크(knock) 신호를 증폭하여 정확한 노크신호를 감지제어가 될 수 있도록 하는 장치에 관한 것이다.The present invention relates to a knock control circuit of a vehicle, and more particularly, to an apparatus for amplifying a knock signal generated in a cylinder of a vehicle engine so that an accurate knock signal can be detected and controlled.

본 발명은 엔진실린더에서 발생되는 노크신호를 노크감지센서가 감지한 후 이를 증폭부에서 마이컴부(MCU)의 제어에 의해 노크신호를 증폭시키는데 다수의 라인을 구비하는 버스선(bus)을 이용하여 상기 마이컴부와 증폭부를 상호접속시켜 제어신호를 인가시키므로서 훨씬 세분화된 제어를 할 수 있다.The present invention uses a bus line (bus) having a plurality of lines to amplify the knock signal by the control of the microcomputer unit (MCU) in the amplifier after detecting the knock signal generated in the engine cylinder. The microcomputer unit and the amplification unit are interconnected to apply a control signal, thereby enabling a much finer control.
