Abstract

본 발명은 호올집적소자를 이용한 차량속도 검출장치의 개량에 관한 것이다, 본 발명은 자기력을 발생시키는 영구자석(1), 차속에 비례하여 회전하며 영구자석(1)에서 발생된 자기력을 단속하는 자기단속부재(2) 및 개방 콜렉터 출력단자를 가지며 영구자석(1)에 대향 설치되어 상기 자기력의 단속에 따른 출력을 발생시키는 호올집적소자(5)를 구비하여 외부의 전자제어유니트에 차속신호를 제공하는 차량속도 검출장치에 있어서, 호올집적소자(5)의 출력단과 전자제어유니트(10~12) 사이에 노이즈방지용 트랜지스터(Q1)를 삽입한 것을 특징으로 한다.The present invention relates to an improvement of an apparatus for detecting a vehicle speed using a hol integrated element. The present invention relates to a permanent magnet (1) for generating a magnetic force, a magnet that rotates in proportion to a vehicle speed and regulates a magnetic force generated in the permanent magnet (1). It has an interlocking member (2) and an open collector output terminal and is provided opposite the permanent magnet (1) to generate an output according to the interruption of the magnetic force to provide a vehicle speed signal to the external electronic control unit In the vehicle speed detecting apparatus, a noise preventing transistor Q1 is inserted between the output terminal of the hol integrated element 5 and the electronic control units 10 to 12.
