본 발명은 하이브리드 차량의 TCS 작동 중 엔진클러치의 접합안정성 향상 및 접합시간 단축을 도모할 수 있도록 한 하이브리드 차량의 TCS 작동 중 엔진클러치 접합 제어 방법에 관한 것이다. 즉, 본 발명은 TCS작동 중 구동륜(전륜) 속도(=모터속도)를 기반으로 엔진클러치 접합 제어가 이루어지던 기존 제어 방식에서 탈피하여, TCS 작동 중 비구동륜(후륜) 속도를 기반으로 엔진클러치 접합 제어가 이루어지도록 함으로써, 엔진클러치의 접합 안정성 향상 및 엔진클러치의 접합 시간 단축을 실현할 수 있는 하이브리드 차량의 TCS 작동 중 엔진클러치 접합 제어 방법을 제공하고자 한 것이다.
A system and method of controlling engine clutch engagement during TCS operation of a hybrid vehicle are provided. The method includes determining whether a TCS is operating and upon determining that the TCS is operating, determining a compensation value for early engagement of an engine clutch during the TCS operation based on a difference between a front wheel speed and a rear wheel speed and a slip amount of front wheels. Additionally, the method includes determining whether engagement of the engine clutch is capable of being started based on the compensation value and starting the engine clutch engagement. Since the engagement of the engine clutch is controlled based on the speed of non-drive wheels during TCS operation, the engagement stability of the engine clutch is improved and the amount of time required to engage the engine clutch is decreased.
