State of charge recovery control is then performed in a next trip to control the engine and the motor such that the state of charge is recovered during operation of the engine. Even when parking is expected at the predetermined point, execution of the state of charge reduction control is restricted in the case where the temperature of the motor is higher than a predetermined temperature. ## Claims ### Claim 1 A hybrid vehicle, comprising: an engine; a motor; a power storage device configured to transmit electric power to and from the motor; and a control device configured
