Abstract
In a hybrid vehicle that includes an engine having a particulate matter removing filter configured to remove particulate matters in an exhaust system, when an increase in temperature of the particulate matter removing filter is requested in order to regenerate the particulate matter removing filter, dither control is executed to execute control such that an air-fuel ratio of the engine is repeated between a rich state and a lean state. Then, when the dither control is executed, control is executed such that the engine is operated at an operation point where the increase in temperature of the particulate matter removing filter is promoted among operation points where power output from the engine is retainable.
