Abstract

본 발명은 자동차 에어백 ECU용 안전 센서를 사전에 테스트하여 에어백의 오전개 방지를 위한 자기 진단 방법에 관한 것이다.The present invention relates to a self-diagnosis method for preventing the opening of an airbag by testing a safety sensor for an automobile airbag ECU in advance.

자장을 감지함으로서 리드 핀(13)를 쇼트시키고 전기적 회로의 전류 패스를 형성시켜주는 리드 스위치(14)와, 자석이 충격의 반대 방향에서 지정된 거리만큼 압축되도록 하는 코일 스프링(12)과, 질량과 자속밀도를 가지고 리드 스위치(14)가 쇼트되도록 자장을 형성시켜주는 펄라이트 마그네트(15)를 구비하는 단계와, 상기 코일 스프링(12)을 도통시키는 단계와, 상기 펄라이트 마그네트(15)에 자장이 형성되어 리드 핀이 크로즈되는 가를 판단하는 단계로 구성된다.A reed switch 14 which senses the magnetic field to shorten the lead pin 13 and forms a current path in the electrical circuit, a coil spring 12 which allows the magnet to be compressed by a specified distance in the opposite direction of the impact, Providing a magnetic field having a magnetic flux density to form a magnetic field such that the reed switch 14 is short-circuited, conducting the coil spring 12 in a conductive state, and a magnetic field is formed in the pearlite magnet 15. And determining whether the lead pin is closed.
