Abstract
In a hybrid vehicle, when the engine is started and caused to make a transition from a stopped state into an operating state, the control device performs an operation control of the rotary machine and an output control of the engine to increase the rotation speed of the engine so that the rotation speed reaches a target rotation speed after the transition of the engine into the operating state, determined by the shifting control, and during increasing the rotation speed, when suppression conditions further including a condition that a vehicle speed is equal to or lower than a predetermined vehicle speed, and a condition that an output request amount by a driver is smaller than a predetermined output request amount, are satisfied, the control device suppresses an increase rate of the rotation speed until a predetermined time elapses from an initiation of starting of the engine as compared with when the suppression conditions are not satisfied.
