Hybrid vehicle, method of controlling hybrid vehicle, program for causing computer to execute the method of controlling hybrid vehicle, and computer readable storage medium having the program stored therein
First Claim
1. A hybrid vehicle comprising:
- an internal combustion engine;
an electric motor used to drive a wheel;
a chargeable and dischargeable electric power storage device supplying said electric motor with electric power;
an electric power generation device receiving mechanical motive power from said internal combustion engine to generate electric power;
an electric power input unit receiving electric power provided from external to the vehicle to charge said electric power storage device; and
a control device controlling an amount charged from said electric power generation device to said electric power storage device to allow said electric power storage device to have an amount of a state, representing a state of charge of said electric power storage device, approaching a target control value, wherein said control device inquires of an occupant of the vehicle whether the occupant has an intention to go to a previously set charging location when the vehicle'"'"'s current position has a distance of at most a predetermined value to said charging location, and said control device changes said target control value in accordance with an instruction of the occupant.

Abstract
The present invention contemplates a hybrid vehicle capable of changing an amount to be charged to an electric power storage device in accordance with whether it is externally charged. The hybrid vehicle includes a control device inquiring of an occupant of the vehicle whether the occupant has an intention to go to a charging location for example at home. If so, the control device sets a target value for the electric power storage device'"'"'s amount of a state (SOC) to have a value smaller than when the occupant does not have an intention to go to the charging location. This allows as much energy as possible to be received at the charging location and a vehicle can thus be obtained that less depends on an internal combustion engine and contributes to environmental protection.

7. A method of controlling with a control device a hybrid vehicle including an internal combustion engine, an electric motor used to drive a wheel, a chargeable and dischargeable electric power storage device supplying said electric motor with electric power, an electric power generation device receiving mechanical motive power from said internal combustion engine to generate electric power, and an electric power input unit receiving electric power provided from external to the vehicle to charge said electric power storage device, the method of using the control device comprising the steps of:
-
inquiring of an occupant of the vehicle whether the occupant has an intention to go to a charging location, said charging location being previously set; controlling first charging, controlling an amount charged from said electric power generation device to said electric power storage device to allow said electric power storage device to have an amount of a state, representing a state of charge of said electric power storage device, approaching a first target control value; controlling second charging, controlling the amount charged from said electric power generation device to said electric power storage device to allow said amount of said state to approach a second target control value lower than said first target control value; determining in accordance with an instruction of the occupant to perform one of the step of controlling said first charging and the step of controlling said second charging; obtaining a distance extending from the vehicle'"'"'s current position to said charging location; and determining whether said distance is at most a predetermined value, wherein the step of inquiring inquires whether the occupant has an intention to go to said charging location when said distance is at most said predetermined value. - View Dependent Claims (8, 9, 10, 11, 12, 13)
