Abstract
When the state of charge of a power storage device is equal to or higher than a predetermined ratio in a specific acceleration time where an acceleration request is equal to or greater than a predetermined level, a hybrid vehicle controls an engine such that the rotation speed of the engine is not increased in a range of an output limit of the power storage device and that the engine is operated at an operation point on a fuel consumption priority operation line. When the state of charge of the power storage device is lower than the predetermined ratio in the specific acceleration time, the hybrid vehicle controls the engine such that the rotation speed of the engine is not increased in the range of the output limit of the power storage device and that the engine is operated at an operation point on a power priority operation line.
