본 발명은 시동발전기의 토크를 최대 토크로 출력하는 엔진 크랭킹 과정 이후, 엔진 초폭 시점을 포함하는 엔진 점화 과정에서 엔진속도 프로파일을 실시간으로 참조하여 실제 엔진속도에 맞게 시동발전기의 토크 감소율을 능동적으로 증가 또는 감소 조절함으로써, 엔진클러치 접합을 위한 엔진속도와 모터속도의 동기화가 용이하게 이루어질 수 있도록 한 하이브리드 차량의 엔진클러치 접합 제어 시스템 및 방법을 제공하고자 한 것이다.
A system for controlling a lock-up of engine clutch may include an engine and a motor; the engine clutch mounted between the engine and the motor and configured to selectively transmit power of the engine between the engine and the motor; a hybrid starter generator (HSG) connected to a crank pulley of the engine and driven to start the engine; and a controller connected to the HSG and configured to determine a virtual engine speed in an engine firing process and a torque reduction ratio of the HSG according to the virtual engine speed after an engine cranking process and determine a correction reduction ratio with respect to the torque reduction ratio of the HSG using a difference value between the virtual engine speed and an actual engine speed, and adjust an increase or a decrease of the torque reduction ratio of the HSG to synchronize an engine speed with a motor speed for the lock-up of the engine clutch.
