HYBRID VEHICLE AND CONTROL METHOD THEREOF

摘要

After completion of warm-up of an engine, upon satisfaction of an exhaust gas recirculation condition by setting the drive mode of a hybrid vehicle to a normal mode according to the driver's accelerator operation, when a power difference DeltaPe representing a decrease rate of a power demand Pe* required for the engine is less than a preset reference value alpha, the engine and motors MG1 and MG2 are controlled to ensure output of a power equivalent to the power demand Pe* from the engine with prohibition for exhaust gas recirculation via an EGR valve and to ensure output of a torque equivalent to a torque demand Tr* to a ring gear shaft or an axle (steps S300 to S330 and step S390).
