Abstract
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.
