The present invention relates to a device and a method for learning a touch point of an engine clutch of a hybrid electric vehicle wherein a touch point of an engine clutch can be learned even during the drive of a hybrid electric vehicle depending on the change of engine torque. The device for learning a touch point of an engine clutch of a hybrid electric vehicle according to an embodiment of the present invention comprises the steps of: determining whether or not the touch of an engine clutch is required after the gear change of a hybrid electric vehicle; determining whether or not the driving state of the hybrid electric vehicle satisfies learning entry conditions if the touch of the engine clutch is required after the gear change; increasing the touch pressure of the engine clutch if the learning entry conditions are satisfied; comparing the change of engine torque, which is caused by the increased touch pressure of the engine clutch, with a set value; and learning a touch point of the engine clutch if the change of the engine torque is greater than or equal to the set value.

    본 발명은 엔진 토크의 변화에 따라 하이브리드 차량의 주행 시에도 엔진 클러치 접합점을 학습할 수 있는 하이브리드 차량의 엔진 클러치 접합점 학습 장치 및 방법에 관한 것이다. 본 발명의 실시예에 따른 하이브리드 차량의 엔진 클러치의 접합점 학습 방법은 하이브리드 차량이 변속 후 엔진 클러치 접합이 요구되는지를 판단하는 단계; 상기 변속 후 엔진 클러치 접합이 요구되면, 하이브리드 차량의 주행 상태가 학습 진입 조건을 만족하는지 판단하는 단계; 상기 학습 진입 조건이 만족되면, 엔진 클러치의 접합 압력을 증가시키는 단계; 상기 증가된 엔진 클러치의 접합 압력에 따른 엔진 토크의 변화량을 설정값과 비교하는 단계; 그리고 상기 엔진 토크의 변화량이 설정값 이상이면, 엔진 클러치의 접합점을 학습하는 단계;를 포함할 수 있다.
