According to the present invention, an apparatus and a method for calibrating a clutch curve of a dual clutch transmission (DCT) system comprises: a clutch curve storing part; and a clutch curve calibrating part. The clutch curve storing part stores a clutch curve identifying a relation with a clutch apply stroke for transferring a transferrable torque and a corresponding torque of an engine. The clutch curve calibrating part performs learning of the clutch curve depending on a drive state of a vehicle, generates a clutch curve in accordance with a learning result, and calibrates the stored clutch curve. The clutch curve calibrating part divides a torque area into a first torque area and a second torque area in accordance with a value of the transferrable torque of the clutch curve, calculates a grade of a line connecting a point of a first learning value as a learning result of the first torque area with a point of a second learning value of a learning result of the second torque area, and generates a clutch curve based on the grade. According to the present invention, when a clutch curve used in the DCT system is calibrated depending on a learning result, a grade of a high torque area can be calibrated in accordance with the characteristics of an actual clutch.

    본 발명에 따른 DCT(Dual Clutch Transmission) 시스템의 클러치 커브 보정 장치는, 엔진의 전달 가능 토크 및 해당 토크를 전달하기 위한 클러치 인가 스트로크의 관계를 정의하는 클러치 커브를 저장하는 클러치 커브 저장부; 및 차량의 주행 상태에 따라, 상기 클러치 커브의 학습을 수행하고 학습 결과에 따라 클러치 커브를 생성하여, 상기 저장된 클러치 커브를 보정하는 클러치 커브 보정부를 포함하며, 상기 클러치 커브 보정부는, 상기 클러치 커브의 엔진의 전달 가능 토크의 값에 따라 제1토크영역 및 제2토크영역으로 구분하고, 상기 제1토크영역에서의 학습 결과인 제1학습값 및 상기 제2토크영역에서의 학습 결과인 제2학습값의 포인트를 연결한 선의 기울기를 계산하고, 상기 기울기에 기초하여 상기 클러치 커브를 생성한다.
