| 发明名称 | Control method for exhaust gas recirculation of hybrid electric vehicle | ||
| 摘要 | A control method for exhaust gas recirculation of a hybrid electric vehicle includes detecting a pressure of an intake manifold. A difference between the pressure of the intake manifold and atmospheric pressure is determined. A load of an engine, which generates torque by combusting a fuel and external air supplied through the intake manifold, is determined. An opening rate of an exhaust gas recirculation valve is controlled to be a first value according to a rotational speed of the engine when the difference is smaller than or equal to a reference pressure and the load of the engine is smaller than or equal to a reference load. | ||

| 主权项 | 1. A control method for exhaust gas recirculation of a hybrid electric vehicle, comprising: detecting a pressure of an intake manifold; determining a difference between the pressure of the intake manifold and atmospheric pressure; determining a load of an engine which generates torque by combusting a fuel and external air supplied through the intake manifold; controlling an opening rate of an exhaust gas recirculation valve to be a first value according to a rotational speed of the engine when the difference is smaller than or equal to a reference pressure and the load of the engine is smaller than or equal to a reference load; and controlling the opening rate of the exhaust gas recirculation valve to be 0 when the difference is smaller than or equal to the reference pressure and the load of the engine is greater than the reference load. | ||
