[산업상 이용분야][Industrial use]

본 발명은 자동 변속차량의 댐퍼 클러치 제어방법에 관한 것으로서, 보다 상세하게는 댐퍼 클러치 작동영역내에서 엔진 브레이크 효과를 얻을 수 있도록 하는 댐퍼 클러치 제어방법에 관한 것이다.The present invention relates to a damper clutch control method for an automatic transmission vehicle, and more particularly, to a damper clutch control method for obtaining an engine brake effect in a damper clutch operating region.

[종래기술][Private Technology]

Doing.

상기한 토오크 컨버터는, 엔진의 크랭크 축에 고정되어 합께 회전하는 임펠러와, 변속기의 입력축에 스플라인으로 결합되어 임펠러와 대향배치되는 터어빈과, 상기한 임펠러와 터어빈 사이에 위치하여 오일의 흐름을 바꾸어 주는 스테이터를 포함하여 이루어진다.The torque converter includes an impeller fixed to the crankshaft of the engine and rotating together, a turbine coupled to the input shaft of the transmission by a spline and disposed between the impeller and the impeller and the turbine to change the flow of oil. It includes a stator.

이러한 토오크 컨버터에는 동력전달 효율을 좋게하여 연비를 향상시킬 수 있는 이른바 댐퍼 클러치가 장착된다.The torque converter is equipped with a so-called damper clutch that can improve fuel efficiency by improving power transmission efficiency.

상기한 댐퍼 클러치는 토오크 컨버터내의 터어빈과 프론트 커버 사이에 장착되어 유압에 의해 이 클러치가 프론트 커버의 내면에 밀착됨으로서 엔진의 동력을 변속기의 입력축으로 직접 전달하게 된다.The damper clutch is mounted between the turbine and the front cover in the torque converter so that the clutch is in close contact with the inner surface of the front cover by hydraulic pressure, thereby directly transmitting the power of the engine to the input shaft of the transmission.

이러한 댐퍼 클러치는 스로틀 개도와 터어빈의 회전수에 관련하여 정하여진 작동영역에서 작동이 이루어진다.This damper clutch is operated in an operating region determined in relation to the throttle opening and the number of revolutions of the turbine.

상기한 댐퍼 클러치의 작동은, 트랜스밋션 제어 유닛(TCU)의 신호에 따라 듀티로 제어되며 전기적인 신호를 유압으로 변환시키는 댐퍼 클러치 컨트롤 솔레노이드 밸브에 의해 유로절환을 행하는 댐퍼 클러치 컨트롤 밸브에 의해 제어된다.The operation of the damper clutch is controlled by the damper clutch control valve which is flow-controlled by the damper clutch control solenoid valve which is controlled duty by the signal of the transmission control unit (TCU) and converts the electrical signal into hydraulic pressure. .

그런 이와 같이 스로틀 밸브의 개도와 엔진의 속도영역에 관련하여 결정되는 댐퍼 클러치 작동영역은 차량이 주행중 돌발적인 상황에 직면하거나 운전자가 엔진 브레이크 효과를 얻어야 하는 상황이 발생하는 경우, 댐퍼 클러치가 해제되므로 엔진 브레이크 효과가 현저히 저하되는 문제점이 있다.As such, the damper clutch operating area determined in relation to the opening of the throttle valve and the speed range of the engine may be released when the vehicle encounters an unexpected situation while driving or when a driver needs to obtain an engine brake effect. There is a problem that the engine brake effect is significantly lowered.
