트랜스미션의 뉴트랄 스위치의 고장 판단방법How to determine fault of neutral switch of transmission

본 발명은 북미 수출용 사양 차종에 적용되고 있는 컴프리센시브 모니터링 항목 중 트랜스미션에 장착되어 있는 뉴트랄 스위치의 고장 판단시 진단하는 기능 로직을 가지는 트랜스미션의 뉴트랄 스위치의 고장 판단방법에 관한 것이다.The present invention relates to a failure determination method of a neutral switch of a transmission having functional logic for diagnosing a failure of a neutral switch mounted on a transmission among the compensatory monitoring items applied to a North American export specification vehicle.

종래의 차량에는 트랜스미션에 뉴트랄 스위치를 부착하고 차량이 중립에 있는지를 ECU에서 판단하게 되어 있으나 뉴트랄 스위치의 고장여부는 알 수 없었다.In a conventional vehicle, the neutral switch is attached to the transmission and the ECU determines whether the vehicle is in neutral, but it is not known whether the neutral switch is broken.

본 발명의 목적은 뉴트랄 스위치의 고장을 판단하도록 차속, 충전효율, 회전수 등을 검출하여 이 값들이 소정치 이상에 있어도 드라이브 레인지라고 판단하지 못하면 뉴트랄 스위치가 고장임을 판단하는 고장판단방법을 제공하고자 하는 것이다.An object of the present invention is to detect a vehicle speed, charging efficiency, the number of revolutions, and the like to determine the failure of the neutral switch, if the value is not determined that the drive range even if the value is above a predetermined value failure determination method for determining that the neutral switch is a failure It is to provide.

본 발명을 첨부된 도면에 도시된 실시예를 참조하여 하기에 설명한다.The invention is described below with reference to the embodiments shown in the accompanying drawings.

제1도에는 본 발명의 뉴트랄 스위치의 고장 판단방법을 수행하는 하드웨어가 도시되는데, 트랜스미션(1)에는 뉴트랄 센서(2)가 부착되고 뉴트랄 센서(2)는 신호를 ECU(3)에 보낸다.FIG. 1 shows hardware for performing the fault determination method of the neutral switch of the present invention, in which the transmission 1 is equipped with a neutral sensor 2 and the neutral sensor 2 transmits a signal to the ECU 3. send.

ECU(3)는 본 발명의 진단로직을 수행하며 각종 시프트 솔레노이드 밸브(4)와 차속센서(5) 및 드로틀 포지션 센서(6)의 신호를 받는다.The ECU 3 performs the diagnostic logic of the present invention and receives signals from various shift solenoid valves 4, vehicle speed sensors 5, and throttle position sensors 6.

제2도에는 본 발명의 뉴트랄 스위치의 고장 판단방법을 수행하는 플로우챠트가 도시되는데, 현재 RPM이 800rpm인가를 판단하고 Yes인 경우에는 충진효율값이 1.0 이상인가를 판단한다. 충진효율값이 1.0 이상이면 차속이 229Km/h 이상인가를 판단하고 Yes인 경우에는 현재 RPM이 이 Target rpm 이상인가를 판단한다.2 is a flow chart for performing the fault determination method of the neutral switch of the present invention, it is determined whether the current RPM is 800rpm, and if yes, it is determined whether the filling efficiency value is 1.0 or more. If the filling efficiency value is 1.0 or more, it is determined whether the vehicle speed is 229 km / h or more, and if yes, it is determined whether the current RPM is more than this target rpm.

현재 RPM이 Target rpm 이상이면 진단허가 flag xioen=1 상태인가를 판단하며 Yes이면 xnldex=1인가, 뉴트랄 상태로 판정하고 있는가를 판단한다.If the current RPM is greater than or equal to the target rpm, it is determined whether the diagnosis permission flag is xioen = 1, and if yes, it is determined whether xnldex = 1 or neutral.

뉴트랄 상태로 판정하고 있다면 지속시간이 33.4초 이상 경과하였는가를 판정하여 Yes이면 뉴트랄 스위치가 고장임을 판정한다.If it is determined to be a neutral state, it is determined whether the duration has elapsed over 33.4 seconds, and if it is yes, it is determined that the neutral switch has failed.

본 발명의 트랜스미션의 뉴트랄 스위치의 고장 진단방법에 따르면, 트랜스미션에 부착된 뉴트랄 센서가 제대로 작동하는 지를 판단하여 북미 수출 차량이 OBD-II의 입출력 사양에 따라 진단을 행할 수 있게 해 준다.According to the method for diagnosing the failure of the neutral switch of the transmission of the present invention, it is possible to determine whether the neutral sensor attached to the transmission is operating properly so that the North American export vehicle can perform diagnosis according to the input / output specification of the OBD-II.
