Abstract

Methods and apparatus are provided for a charging receptacle lock. The method includes receiving a speed of the vehicle, and receiving sensor data indicating a position of a door covering a receptacle associated with the charging system of the vehicle. The receptacle adapted to receive a connecting device of an external power supply. The method includes outputting one or more control signals to move a lock pin associated with the receptacle between a first, extended position and a second, refracted position based on the speed of the vehicle and the position of the door.

Claims

1. A method of controlling a charging system of a vehicle, comprising the steps of:

receiving a speed of the vehicle;

receiving sensor data indicating a position of a door covering a receptacle associated with the charging system of the vehicle, the receptacle adapted to receive a connecting device of an external power supply; and

outputting one or more control signals to move a lock pin associated with the receptacle between a first, extended position and a second, retracted position based on the speed of the vehicle and the position of the door.

2. The method of claim 1, wherein the receptacle includes an interface, and in the second, retracted position, the connecting device of the external power supply is couplable to the interface.

3. The method of claim 2, wherein in the first, extended position, the lock pin prevents coupling the connecting device of the external power supply to the interface.

4. The method of claim 1, further comprising:

receiving a gear range of a transmission associated with the vehicle; and

outputting the one or more control signals to move the lock pin based on the gear range of the transmission.

5. The method of claim 1, further comprising:

receiving a power status of an ignition associated with the vehicle; and

outputting the one or more control signals to move the lock pin based on the power status of the ignition.

6. The method of claim 1, wherein outputting the one or more control signals to move the lock pin between the first, extended position and the second, retracted position further comprises:

moving the lock pin from the first, extended position to the second, retracted position based on the speed of the vehicle being less than a predetermined threshold speed and the position of the door being open.

7. The method of claim 1, wherein outputting the one or more control signals to move the lock pin between the first, extended position and the second, retracted position further comprises:

moving the lock pin from the second, retracted position to the first, extended position based on the speed of the vehicle being greater than a predetermined threshold speed and the position of the door being closed.

8. The method of claim 2, further comprising:

receiving data regarding a condition of the interface; and

outputting the one or more control signals to move the lock pin based on the condition of the interface.

9. A charging system for a vehicle, comprising:

a receptacle for receiving a connecting device of an external power supply;

a lock pin associated with the receptacle and movable between a first, extended position and a second, refracted position;

a source of range data that indicates a range of a transmission of the vehicle;

a source of speed data that indicates a speed of the vehicle; and

a control module that generates one or more control signals to move the lock pin between the first, extended position and the second, retracted position based on the range data and the speed data.

10. The charging system of claim 9, wherein the receptacle includes an interface, and in the second, retracted position, the connecting device of the external power supply is couplable to the interface.

11. The charging system of claim 10, wherein in the first, extended position, the lock pin prevents coupling the connecting device of the external power supply to the interface.

12. The charging system of claim 9, further comprising:

source of ignition data that indicates a power status of an ignition associated with the vehicle,

wherein the control module generates the one or more control signals to move the lock pin based on the power status of the ignition.

13. The charging system of claim 9, further comprising:

source of door data that indicates a position of a door associated with the receptacle,

wherein the control module generates the one or more control signals to move the lock pin based on the position of the door.

14. The charging system of claim 9, wherein the control module generates the one or more control signals to move the lock pin to the second, refracted position from the first, extended position when the transmission is in a park range and the speed of the vehicle is less than a predetermined threshold speed.

15. The charging system of claim 13, wherein the control module generates the one or more control signals to move the lock pin to the second, retracted position from the first, extended position when the transmission is in a park range, the speed of the vehicle is less than a predetermined threshold speed and the position of the door is open.

16. The charging system of claim 12, wherein the control module generates the one or more control signals to move the lock pin to the second, retracted position from the first, extended position when the transmission is in a park range, the speed of the vehicle is less than a predetermined threshold speed and the power status of the ignition is off.

17. A method of controlling a charging system of a vehicle, comprising the steps of:

receiving a range of a transmission associated with the vehicle;

receiving sensor data indicating a position of a door covering a receptacle associated with the charging system of the vehicle, the receptacle including an interface for coupling a connecting device of an external power supply to the vehicle; and

outputting one or more control signals to move a lock pin associated with the receptacle from a first, extended position to a second, retracted position to enable the coupling of the connecting device to the interface based on the range of the transmission and the position of the door.

18. The method of claim 17, wherein in the first, extended position, the lock pin prevents coupling the connecting device of the external power supply to the interface.

19. The method of claim 17, further comprising:

receiving a power status of an ignition associated with the vehicle; and

outputting the one or more control signals to move the lock pin based on the power status of the ignition.

20. The method of claim 17, further comprising:

receiving a speed of the vehicle; and

outputting the one or more control signals to move the lock pin based on the speed of the vehicle.
