하이브리드 차량의 엔진 클러치 접합점 학습 방법은, 제어기가 엔진 및 모터의 정지를 확인한 후 엔진과 모터를 연결 또는 분리하는 엔진 클러치를 결합하고 엔진 클러치의 유압 라인에 대한 안정화 동작을 수행하도록 엔진 클러치를 제어하는 단계와, 안정화 동작이 수행된 후, 제어기가 모터가 일정 속도를 가지도록 제어하는 단계와, 모터의 속도가 안정화된 후, 제어기가 엔진 클러치가 연결되도록 제어하는 단계와, 제어기가 엔진 클러치가 연결될 때 발생하는 모터의 토크 변화가 기준값 이상인 지 여부를 판단하는 단계와, 제어기가 모터의 토크 변화가 기준값일 때의 유압을 엔진 클러치의 접합점으로 결정하는 단계를 포함한다.

    A method for learning an engine clutch kiss point of a hybrid vehicle includes: controlling, by a controller, an engine clutch which connects an engine with a motor or disconnects the engine from the motor so that the engine clutch is engaged after the controller checks stop of the engine and of the motor and stabilization operation for a hydraulic pressure line of the engine clutch is performed; controlling the motor to have a certain speed after the stabilization operation; controlling the engine clutch to be engaged after speed of the motor is stabilized; determining whether torque variation of the motor when the engine clutch is engaged is equal to or greater than a threshold value; and determining a hydraulic pressure at which the torque variation is the threshold value as the kiss point of the engine clutch.
