Abstract

본 발명은 페일 세이프 기능을 지닌 자동차의 자동변속기에 있어서 변속계통의 고장 발생시 댐퍼클러치의 작동을 제어하는 방법에 관한 것으로, 페일 세이프 기능을 지닌 자동변속기에서 가령 쓰로틀 밸브 또는 펄스 제네레이터 등에 페일 발생시 엔진 회전수를 검출하여, 검출된 회전수가 설정된 소정의 회전수 보다 높을 경우 댐퍼클러치를 작동시켜 자동 변속기 오일의 과열을 방지한다.The present invention relates to a method for controlling the operation of the damper clutch in the event of a failure of the transmission system in an automatic transmission of a vehicle having a fail safe function. The number is detected, and when the detected rotation speed is higher than the predetermined predetermined rotation speed, the damper clutch is operated to prevent overheating of the automatic transmission oil.
