본 발명은 보다 효과적인 촉매 히팅 제어 시점의 선정과 선정된 시점에 따른 후속 대응이 가능한 하이브리드 자동차 및 그를 위한 촉매 히팅 제어 방법에 관한 것이다. 본 발명의 일 실시예에 따른 하이브리드 자동차의 촉매 가열 제어 방법은, 구동 모터만 구동원으로 사용하는 제1 모드에서 구동축과 엔진이 단절된 상태에서 상기 엔진을 구동하는 제2 모드로 진입하여 상기 엔진의 촉매 가열을 시작하는 단계; 및 상기 촉매 가열이 완료되기 전에 상기 구동 모터의 최대 출력을 상회하는 요구 토크가 발생할 경우, 상기 요구 토크가 상기 최대 출력에 일정 마진을 더한 값을 상회하기 전까지 상기 제2 모드를 유지하는 단계를 포함할 수 있다.

    A hybrid electric vehicle and a catalyst heating control method are configured to select a point in time at which catalyst heating control is performed and to perform a follow-up measure based on the selected point in time. The catalyst heating control method includes performing mode switching from a first mode in which only a drive motor is used as a driving source to a second mode in which an engine is driven in a state in which a drive shaft and the engine are disconnected from each other to start heating of a catalyst of the engine. When demand torque higher than a maximum output of the drive motor occurs before the catalyst heating is completed, the second mode is maintained until the demand torque is greater than the sum of the maximum output and a predetermined margin.
