HYBRID VEHICLE AND CONTROL METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a hybrid vehicle provided with an internal combustion engine having an exhaust gas recirculation means for suppressing misfire in the internal combustion engine due to the exhaust gas recirculation.

SOLUTION: After completion of warm-up of an engine 22, upon satisfaction of an exhaust gas recirculation condition by setting the drive mode of a hybrid vehicle 20 to a normal mode according to the driver's accelerator operation, when a power difference ΔPe representing a decrease rate of a power demand Pe* required for the engine 22 is less than a preset reference value α, the engine 22 and motors MG1 and MG2 are controlled to ensure output of a power equivalent to the power demand Pe* from the engine 22 with prohibition for exhaust gas recirculation via an EGR valve 143 and to ensure output of a torque equivalent to a torque demand Tr* to a ring gear shaft 32a or an axle (steps S300 to S330 and step S390).
