A method for learning an engine clutch transmission torque of a hybrid vehicle comprises: a step in which a controller determines whether a power transmission from a transmission, which delivers output power of an engine and output power of a motor, is disconnected; a step in which, when the power transmission from the transmission is disconnected, the controller controls a speed of the motor such that the speed of the motor is maintained at a first speed; a step in which the controller calculates a first transmission torque of an engine clutch based on a second speed of the motor, which is generated after the engine clutch, which couples or separates the engine with or from the engine, is concatenated, and the first speed; a step in which, after the first transmission torque is calculated, the controller releases the engine clutch and controls the speed of the motor to be maintained at the second speed; and a step in which the controller calculates a second transmission torque of the engine clutch based on a third speed of the motor, which is generated after the engine clutch is concatenated, and the second speed. According to the present invention,, transmission torques related to different speeds of an engine clutch can be learned.
하이브리드 차량의 엔진 클러치 전달토크 학습방법은, 제어기가 엔진의 출력과 모터의 출력을 전달하는 변속기의 동력전달이 차단된 상태인 지 여부를 판단하는 단계와, 변속기의 동력전달이 차단된 상태일 때, 제어기가 모터의 속도를 제1 속도로 유지하도록 제어하는 단계와, 제어기가 엔진과 모터를 연결 또는 분리하는 엔진 클러치가 접합된 후 생성되는 모터의 제2 속도와 제1 속도에 근거하여 엔진 클러치의 제1 전달 토크를 계산하는 단계와, 제어기가 제1 전달 토크를 계산한 후 엔진 클러치를 해제하여 모터의 속도를 제2 속도로 유지하도록 제어하는 단계와, 제어기가 엔진 클러치가 접합된 후 생성되는 모터의 제3 속도와 제2 속도에 근거하여 엔진 클러치의 제2 전달 토크를 계산하는 단계를 포함한다.
