Suggested is a gasoline particulate filter (GPF) regeneration control system for a hybrid vehicle, including: a GPF filtering soot contained in combustion gas discharged from an engine; a generation determination part monitoring the condition of the GPF and determining whether the regeneration of the GPF is required based on the monitored condition of the GPF; a generation means selection part selecting, as a GPF generation means, at least one of a clutch which regulates connection between a driving motor and an engine based on the monitored condition of the GPF or the driving condition of the vehicle and a hybrid starter generator (HSG) which is connected to the engine to rotate along with the same if the generation of the GPF is determined to be required by the generation determination part; and an HSG controller controlling the rpm of the HSG if the HSG is selected as a GPF generation means by the generation means selection part. Therefore, the GPF regeneration control system is capable of improving drivability as well as increasing fuel efficiency.
엔진에서 배출된 연소 가스에 포함된 Soot를 필터링하는 GPF(Gasoline Particulate Filter); GPF의 상태를 모니터링하고, 모니터링한 GPF의 상태를 기반으로 GPF의 재생이 필요한지 여부를 판단하는 재생 판단부; 재생 판단부에서 GPF의 재생이 필요한 것으로 판단된 경우, 모니터링한 GPF의 상태 또는 차량의 주행 상태를 기반으로 엔진과 구동모터 사이의 연결을 단속하는 클러치 및 엔진과 연결되어 엔진과 함께 회전하는 HSG(Hybrid Starter Generator) 중 어느 하나 이상을 GPF 재생 수단으로 선택하는 재생 수단 선택부; 및 재생 수단 선택부에서 HSG가 GPF 재생 수단으로 선택된 경우, HSG의 회전속도를 제어하는 HSG 제어기;를 포함하는 하이브리드 차량의 GPF 재생 제어시스템이 소개된다.
