Abstract

According to an embodiment of the present invention, a particulate filter regeneration method of a diesel hybrid vehicle comprises the following steps of: determining whether a regeneration condition for a particulate filter that filters particulate matter in an exhaust gas discharged from an engine; entering a mode for increasing the temperature of the exhaust gas when the regeneration condition may be satisfied; increasing output torque of the engine to increase the temperature of the exhaust gas; determining redundant torque by subtracting current demand torque required for operation of the engine from the increased output torque; generating electricity by a motor by using the redundant torque; and storing the electricity generated by the motor in a battery.

Description

디젤 하이브리드 자동차의 매연필터 재생방법{PARTICULATE FILTER REGENERATION METHOD OF DIESEL HYBRID VEHICLE}FIELD OF THE INVENTION [0001] The present invention relates to a particulate filter regeneration method for a diesel hybrid vehicle,

본 발명은 디젤엔진과 주행모터를 이용하여 연료소모를 줄이고, 배기가스에포함된 입장상 물질의 배출량을 저감시켜 환경오염을 줄일 수 있는 디젤 하이브리드 자동차의 매연필터 재생방법에 관한 것이다. The present invention relates to a soot filter regeneration method for a diesel hybrid vehicle in which fuel consumption is reduced by using a diesel engine and a traveling motor, and the amount of exhausted substances contained in the exhaust gas is reduced to reduce environmental pollution.

일반적으로, 디젤 입자상 물질의 재생 방식은 별도의 열원 공급없이 배출가스만으로 재생이 이루어지는 자연재생 방식(Passive type)과 강제로 화학적열원을 공급하여 입자상 물질을 연소시키는 강제 재생 방식이 있다.In general, the regeneration method of the diesel particulate matter is a passive type in which regeneration is performed by only exhaust gas without supplying a separate heat source, and a forced regeneration method in which particulate matter is burned by forcibly supplying a chemical heat source.

여기서, 자연재생 방식은 철(Fe), 세륨(Ce), 구리(Cu), 백금(Pt) 등의 금속 물질을 연료에 혼합함으로써 입자상 물질을 재생온도를 낮추거나 백금 등의 귀금속을 필터 표면에 코팅하여 입자상 물질을 연소시키는 산화촉매 필터 방식, 입자상 물질을 직접 걸려내는 매연 필터를 설치하는 방식이 있다.  Here, the natural regeneration method is a method in which a regeneration temperature of particulate matter is lowered by mixing metallic materials such as iron (Fe), cerium (Ce), copper (Cu), and platinum An oxidation catalyst filter method in which particulate matter is burned by coating, and a soot filter in which particulate matter is directly caught is installed.

여기서, 매연 필터를 통해 입자상 물질을 포집한 다음 입자상 물질을 직접 연소시키거나 연소가 가능한 온도까지 가열하는 방식이다. 또한, 커먼레일 방식 디젤엔진에서 배기과정 후반에 연료를 분사시켜 연소시킴으로서 배출가스 온도를 증가 시키고 이로서 포집된 입자상 물질을 연소시킨다.  Here, the particulate matter is collected through the soot filter, and then the particulate matter is directly combusted or heated to a temperature at which combustion is possible. In a common-rail diesel engine, the fuel is injected and combusted at the latter stage of the exhaust process to increase the temperature of the exhaust gas, thereby burning the particulate matter collected.

최근에는, 디젤엔진에 주행모터를 결합하는 디젤 하이브리드 자동차가 연구 개발되고 있으며, 디젤 하이브리드 자동차는 배터리에 저장된 전기에너지를 이용하여 주행모터가 엔진을 보조하거나, 주행모터로만 주행을 수행하여 연료소모를 획기적으로 줄일 수 있다. Recently, a diesel hybrid vehicle that combines a driving motor with a diesel engine has been researched and developed. The diesel hybrid vehicle uses electric energy stored in the battery to assist the driving motor to support the engine, or to run only with the traveling motor, Can be dramatically reduced.

한편, 이러한 디젤 하이브리드 자동차에서 매연필터를 재생하기 위해서 배기가스의 온도를 상승시키는데, 이와 같이 배기가스의 온도를 상승시키기 위해서 후분사를 수행하는 경우에 출력은 거의 변화가 없고, 연료소모가 늘어난다. On the other hand, in order to regenerate the particulate filter in such a diesel hybrid vehicle, the temperature of the exhaust gas is raised. When the post-injection is performed in order to raise the temperature of the exhaust gas, the output is hardly changed and the fuel consumption is increased.

본 발명의 목적은 디젤매연필터를 재생시키기 위해서 배기가스의 온도를 상승시키되, 연료소모를 줄이는 동시에 이를 회수하여 운행비용을 절감할 수 있는 디젤 하이브리드 자동차의 매연필터 재생방법을 제공하는 것이다. An object of the present invention is to provide a soot filter regeneration method of a diesel hybrid vehicle in which the temperature of the exhaust gas is raised to regenerate the diesel particulate filter, and the fuel consumption can be reduced while recovering the fuel consumption.

상술한 바와 같이 본 발명의 실시예에 따른 디젤 하이브리드 자동차의 매연필터 재생방법에 의하면, 엔진에서 배출되는 배기가스에 포함된 입자상물질을 거르는 매연필터의 재생조건을 판단하는 단계, 상기 재생조건이 만족되면, 배기가스의 온도상승 모드에 진입하는 단계, 배기가스의 온도를 상승시키기 위해서 출력토크를 상승시키는 단계, 상승된 출력토크에서 상기 엔진의 운전에 필요한 현재요구토크를 차감하여 잉여토크를 연산하는 단계, 상기 잉여토크를 이용하여 모터가 발전을 수행하는 단계, 및 상기 모터에서 생성된 전기를 배터리에 충전하는 단계를 포함할 수 있다.
