Abstract

본 발명은 시동이 켜져 있는 상태임에도 불구하고 운전자의 착각에 의하여 시동을 켜기 위하여 다시 시동 키이를 돌려 스타트 모터를 가동시킬 경우,스타트 모터에 무리를 주는 것을 방지하기 위한 스타트 모터 손상 방지 장치에 관한 것이다.이같은 본 발명은,자동차의 엔진 회전수를 체크하고,만약 시동키이가 돌려져 스타트 릴레이를 동작시키려고 할때 상기 마이컴이 체크한 자동차 엔진 회전수가 소정치 이하이면 엔진이 정지되어 있는 것으로 판단하여 스타트 릴레이를 구동시키게 하고,상기 마이컴이 체크한 자동차 엔진 회전수가 소정치 이상이면 시동이 켜져 있는 것으로 판단하여 스타트 릴레이가 동작하는 것을 방지함으로써 재시동에 의한 스타트 모터의 손상을 효과적으로 방지될 수 있도록 하는 것이다.The present invention relates to a start motor damage prevention device for preventing an excessive load on the start motor when the start key is rotated to turn on the start by the driver's illusion even though the start is turned on. The present invention checks the engine speed of the vehicle, and if the start key is turned to operate the start relay, it is determined that the engine is stopped if the engine engine speed checked by the microcomputer is less than or equal to a predetermined value. When the engine speed of the car checked by the microcomputer is more than a predetermined value, the starter is determined to be turned on, and the start relay is prevented from operating so that damage to the start motor due to restarting can be effectively prevented.
