Abstract

In response to detection of connection between a power supply outside a vehicle and a charge plug, control device invalidates key verification performed for determining whether a key of a user is regular or not, when a shift position is parking and a parking brake is active. This satisfies system start conditions, and the control device turns on respective relays to start a system, and executes charge control for charging a power storage device from the power supply outside the vehicle.

Claims

1. A vehicle comprising:

a power storage device capable of being charged;

a charge plug for receiving an electric power for charging said power storage device from a power supply outside the vehicle;

charging means configured to be capable of receiving the electric power input from said charge plug and charging said power storage device;

authenticating means for determining whether a user is a regular user or not, and allowing starting of a vehicle system when it is determined that the user is the regular user; and

control means for starting said vehicle system independently of the determination result of said authenticating means when said power storage device is charged from said power supply.

2. The vehicle according to claim 1, further comprising:

connection detecting means for detecting connection or disconnection between said charge plug and said power supply, wherein

said control means starts said vehicle system independently of the determination result of said authenticating means when said connection detecting means detects the connection between said charge plug and said power supply during stop of said vehicle system.

3. The vehicle according to claim 1, wherein

said control means invalidates the determination result of said authenticating means and instructs said charging means to execute the charging of said power storage device from said power supply, when said power storage device is to be charged from said power supply.

4. A control method for a vehicle allowing charging of a power storage device mounted on the vehicle from a power supply outside the vehicle, wherein

said vehicle includes authenticating means for determining whether a user is a regular user or not, and allowing starting of a vehicle system when it is determined that the user is the regular user, and

said control method comprises:

a step of starting said vehicle system independently of the determination result of said authenticating means when said power storage device is to be charged from said power supply; and

a step of executing the charging of said power storage device from said power supply when said vehicle system starts.

5. The control method according to claim 4, further comprising:

a step of detecting the connection between said power supply and a charge plug receiving the electric power for charging said power storage device from said power supply, wherein

said vehicle system is started in the step of starting said vehicle system independently of the determination result of said authenticating means, when the connection between said charge plug and said power supply is detected during stop of said vehicle system.

6. The control method according to claim 4, further comprising:

a step of invalidating the determination result of said authenticating means at the time of charging said power storage device from said power supply, wherein

said vehicle system starts and the charging of said power storage device from said power supply is executed when the determination result of said authenticating means is invalidated.

7. A vehicle comprising:

a power storage device capable of being charged;

a charge plug for receiving an electric power for charging said power storage device from a power supply outside the vehicle;

a charging device configured to be capable of receiving the electric power input from said charge plug and charging said power storage device; and

a control device executing a series of process, wherein

said control device determines whether a user is a regular user or not, allows starting of a vehicle system when it is determined that the user is the regular user, and starts said vehicle system independently of a result of the determination whether the user is the regular user or not, at the time of charging said power storage device from said power supply.

8. The vehicle according to claim 7, wherein

said control device detects the connection or disconnection between said charge plug and said power supply, and when the connection between said charge plug and said power supply is detected during stop of said vehicle system, said control device starts said vehicle system independently of the result of the determination whether the user is the regular user or not.

9. The vehicle according to claim 8, wherein

when said power storage device is to be charged from said power supply, said control device invalidates the result of the determination whether the user is the regular user or not, and instructs said charging device to execute the charging of said power storage device from said power supply.
