Abstract
본 발명은 자동차의 자동변속기에 사용되는 ATF(자동변속기 액)의 온도를 감지하여 ATF의 온도가 높을때 록업 모우드로 변속함으로써 마찰열을 낮춰 자동변속기를 보호할 수 있도록 하는 자동변속차량의 ATF 고온시 자동변속기 보호를 위한 강제 록업장치에 관한 것이다.The present invention relates to an ATF (Automatic Transmission Fluid) of an automatic transmission which is capable of protecting an automatic transmission by lowering frictional heat by shifting to a lockup mode when the ATF temperature is high, To a forced lockup device for automatic transmission protection.
종래 자동변속차량에 있어 ATF시 고온인 상태로 주행하게 되는 경우 ATF의 점도 불량 및 변속기의 마찰열 증가고 내구성에 문제가 발생되고 연비가 낮아지는 등의 문제점이 있다.In the conventional automatic transmission, there is a problem in that when the AT is running at a high temperature in the ATF, the ATF has a bad viscosity, a frictional heat increases in the transmission, a problem in high durability, and a low fuel efficiency.
본 발명은 자동변속차량에서 D레인지 주행인 경우 차속센서와 드로틀위치센서의 감지신호에 따라 시프트패턴에 의거 변속작동을 수행하도록 하는 자동변속차량의 시프트방법에 있어서, 상기 차속신호와 드로틀위치신호에 따라 시프트패턴을 수행하는 과정중 자동변속기 액의 온도가 약 145℃의 고온인 경우에는 룩업 솔레노이드 밸브를 작동시켜 록업시프트 패턴에 의한 록업작용을 수행하도록 이루어진 발명임.A shift method of an automatic transmission vehicle that performs a shift operation based on a shift pattern in response to a detection signal of a vehicle speed sensor and a throttle position sensor in the case of a D range travel in an automatic transmission vehicle, When the temperature of the automatic transmission fluid is a high temperature of about 145 캜 during the process of performing the shift pattern, the lockup solenoid valve operates the lock-up shift pattern by operating the look-up solenoid valve.
