State of charge recovery control is performed in a next trip to control the engine and motor, such that the state of charge is recovered during operation of the engine. When parking at the predetermined point is expected based on a destination that is estimated by a vehicle exterior system, the state of charge reduction control is performed by a first procedure. When parking at the predetermined point is expected based on a destination that is set by the user, the state of charge reduction control is performed by a second procedure. ## Claims ### Claim 1 A hybrid vehicle, comprising: an engine;
