Disclosed are a method and a device for controlling an engine clutch of a hybrid vehicle, capable of improving driving responsiveness of the hybrid vehicle by learning a kiss point of an engine clutch. The method includes the steps of: setting, by a controller, a target speed of an engine to change a driving mode of the hybrid vehicle from an electric vehicle (EV) mode to an hybrid electric vehicle (HEV) mode; operating, by the controller, a hybrid starter-generator (HSG) to adjust a speed of the engine to follow the target speed; engaging, by the controller, an engine clutch that connects the engine with a driving motor or disconnects the engine from the driving motor to start when the speed of the engine is maintained at the target speed; detecting, by the controller, a kiss point generated when the engine clutch is in a slip state to learn the kiss point of the engine clutch; and increasing, by the controller, an output of the engine based on a torque required by a driver of the hybrid vehicle when the speed of the engine and a speed of the driving motor are synchronized after the kiss point is learned.

    하이브리드 차량의 엔진 클러치 제어 방법은, 제어기가 하이브리드 차량의 주행 모드를 EV 모드(electric vehicle mode)로부터 HEV 모드(hybrid electric vehicle mode)로 전환하기 위한 엔진의 목표 속도를 설정하고 하이브리드 시동 발전기를 제어하여 엔진의 속도가 목표 속도가 되도록 제어하는 단계와, 엔진의 속도가 목표 속도로 유지될 때, 제어기가 엔진과 구동 모터를 연결 또는 분리하는 엔진 클러치의 결합이 시작되도록 제어하는 단계와, 제어기가 엔진 클러치가 슬립 결합될 때 생성되는 엔진 클러치의 접합점을 검출하여 엔진 클러치의 접합점을 학습하는 단계와, 엔진 클러치의 접합점이 학습된 후 엔진의 속도와 구동 모터의 속도가 동기화될 때, 제어기가 하이브리드 차량의 운전자의 요구 토크에 근거하여 엔진의 출력을 증가시키는 단계를 포함한다.
