Disclosed is a method for controlling diesel particulate filter (DPF) regeneration for a hybrid vehicle using a diesel engine and an electric motor. According to an embodiment of the present invention, the method for controlling DPF regeneration comprises: (a) a pre-regeneration step of burning a part of particulate matters (PM) collected in the DPF; and (b) a post-regeneration step of burning the remaining part of the PM collected in the DPF. The pre-regeneration step is performed while distributing power to the diesel engine and the electric motor to set an operation condition of the diesel engine as the first operation condition where the temperature of exhaust gas of the diesel engine is a preset reference temperature or more. According to the present invention, a problem where the DPF is damaged due to an excessive increase of the inside temperature of the DPF in an initial step of the DPF regeneration can be resolved.

    디젤 엔진과 전기 모터를 사용하는 하이브리드 차량용 DPF 재생 (디젤입자필터 재생: Diesel Particulate Filter regeneration) 제어 방법이 개시된다. 본 발명의 일 실시예에 따르면, 상기 제어 방법은, (a) 상기 DPF에 포집된 입자상 물질들(PM: particulate matters) 중 일부를 연소시키는 선-재생 단계; 및 (b) 상기 DPF에 포집된 입자상 물질들 중 나머지 부분을 연소시키는 후-재생 단계;를 포함하며, 상기 선-재생 단계는 상기 디젤 엔진의 배기 가스 온도가 기 설정된 기준 온도 이상으로 나타나는 제1 운전 조건으로 상기 디젤 엔진의 운전 조건이 설정되도록 상기 디젤 엔진과 상기 전기 모터에 동력을 배분하면서 수행된다.
