Abstract

When parking is expected at a predetermined point, state of charge reduction control is performed in a current trip to control an engine and a motor, such that the state of charge of a power storage device is lower than the state of charge of the power storage device when parking is not expected at the predetermined point. 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.

Dependent claims

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 to, when parking is expected at a predetermined point, perform state of charge reduction control in a current trip and to perform state of charge recovery control in a next trip, wherein the state of charge reduction control controls the engine and the motor such that state of charge of the power storage device when parking is expected at the predetermined point is lower than the state of charge of the power storage device when parking is not expected at the predetermined point, and the state of charge recovery control controls the engine and the motor such that the state of charge of the power storage device is recovered during operation of the engine, wherein
when parking at the predetermined point is expected based on a destination that is not set by a user but that is estimated by a vehicle exterior system, the control device performs the state of charge reduction control by a first procedure, and
when parking at the predetermined point is expected based on a destination that is set by the user, the control device performs the state of charge reduction control by a second procedure that is different from the first procedure.
