Disclosed is an exhaust gas reduction system of a hybrid vehicle and a method thereof. According to an embodiment of the present invention, the exhaust gas reduction system of a hybrid vehicle includes: a battery management unit which measures the state of charge (SOC) regarding a high-voltage battery of the hybrid vehicle; a motor controller which controls a driving motor as a power source of the high-voltage battery and generates a motor driving force; an engine controller which drives an engine in accordance with an applied control command to generate and engine driving force; and a hybrid controller which checks an all-electric range (AER) in accordance with a charge-depleting (CD) mode operation of the hybrid vehicle and executes catalyst and warm-up control operations by driving the engine in the CD mode when the AER exceeds a preset reference AER.

    하이브리드 차량의 배기가스 저감 시스템 및 그 방법이 개시된다. 본 발명의 실시 예에 따른 하이브리드 차량의 배기가스 저감 시스템은, 하이브리드 차량의 고전압 배터리 충전상태(SOC)를 측정하는 배터리 관리부; 상기 고전압 배터리의 전원으로 구동모터를 제어하여 모터 구동력을 생성하는 모터 제어기; 인가되는 제어 지령에 따라 엔진을 기동하여 엔진 구동력을 생성하는 엔진 제어기; 및 상기 하이브리드 차량의 CD(Charge Depleting) 모드 운행에 따른 순수전기주행거리(All Electric Range, AER)를 체크하여 미리 설정된 기준 AER을 초과한 경우 상기 CD 모드에서 엔진을 기동하여 촉매 히팅 및 웜업 제어를 수행하는 하이브리드 제어기를 포함한다.
