Abstract

본 발명은 북미 수출용 사양 차종에 적용되고 있는 컴프리헨시브 모니터링항목 중 트랜스미션에 장착되어 있는 뉴트랄 스위치의 고장 판단시 진단하는 기능 로직을 가지는 트랜스미션의 뉴트랄 스위치의 고장 판단방법에 관한 것으로 차속, 충전효율, 회전수 등을 검출하여 이 값들이 소정치 이상에 있어도 드라이브 레인지라고 판단하지 못하면 뉴트랄 스위치가 고장임을 판단한다.The present invention relates to a method for determining the failure of a transmission's neutral switch having a function logic for diagnosing a failure of a neutral switch mounted on a transmission, among complementary monitoring items applied to a specification vehicle for North American export, Efficiency, and the number of revolutions of the motor, and if it is determined that these values are not within the drive range even if they are greater than a predetermined value, it is determined that the neural switch is malfunctioning.

Description

Claims (1)

차속, 충전효율, 회전수 등을 검출하여 현재 PRM이 소정치 이상인가를 판단하고 충진효율값이 소정치 이상인가를 판단하며 차속이 소정치 이상인가를 판단하고 현재 RPM 이 Target rpm 이상인가를 판단하며 진단 허가 상태인가를 판단하고 뉴트랄 상태로 판정하고 있는가를 판단하며 지속시간이 소정치 이상 경과하였는가를 판정하여 뉴트랄 스위치가 고장임을 판정하는 트랜스미션의 뉴트랄 스위치의 고장판단방법.It determines whether the PRM is greater than or equal to a predetermined value, determines that the filling efficiency is greater than or equal to a predetermined value, determines whether the vehicle speed is greater than or equal to a predetermined value, and determines whether the RPM is equal to or greater than the target rpm Judging whether or not the diagnosis is permitted, judging whether or not it is judged to be in the neural state, and judging whether or not the duration has exceeded the predetermined value, and judging that the neural switch is faulty. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
