Abstract

Embodiments described herein describe an immobilization device configured to simulate the communication of safety signals of a charging cable to a charging port of an electric vehicle; such that a processor of the electric vehicle may determine that the charging state of electric vehicle is ready to charge, thus immobilizing the vehicle. In embodiments, the immobilization device may be configured to restrict the movement of the electric vehicle without supplying power to the electric vehicle, and be configured to allow the components of the electric vehicle to be utilized if the immobilization device is coupled to the charging port of the electric vehicle.

Claims

1. A system for immobilizing a vehicle, the system comprising:

a processor configured to determine a charging state of the vehicle, wherein when the charging state of the vehicle is ready to charge then the vehicle is immobilized;

a charging port configured to be disposed within the vehicle;

an immobilization device including a charging port interface configured to be coupled with the charging port, the charging port interface being configured to communicate signals to the processor through the charging port to change the charging state of the vehicle to ready to charge.

2. The system of claim 1, wherein the charging port interface is configured to simulate that the vehicle is being charged without charging the vehicle.

3. The system of claim 1, further comprising:

at least one component of the vehicle, wherein the at least one component of the vehicle is operable when the charging port interface is coupled to the charging port.

4. The system of claim 3, wherein the at least one component of the vehicle includes power windows, air-conditioning, power locks, opening a trunk, and a radio.

5. The system of claim 1, further comprising:

an authorized key configured to authenticate a user of the vehicle responsive to determining that the authorized key is engaged with the vehicle, wherein the charging port interface is configured to immobilize the vehicle when the authorized key is engaged with the vehicle.

6. The system of claim 5, wherein the authorized key configured to be physically or wirelessly engaged with the vehicle.

7. The system of claim 1, wherein when the charging state of the vehicle is passive the vehicle is mobile.

8. The system of claim 7, wherein the signals communicated from the charging port interface are configured to change the charging state of the vehicle from passive to ready to charge.

9. The system of claim 1, wherein responsive to decoupling the charging port interface from the charging port, the charging state of the vehicle is changed from ready to charge to passive.

10. The system of claim 1, wherein the charging port interface is configured to transmit the signals to the processor without transmitting power signals.

11. A method for immobilizing a vehicle, the method comprising:

determining a charging state of the vehicle, wherein when the charging state of the vehicle is ready to charge then the vehicle is immobilized;

coupling a charging port interface, positioned on a mobile immobilization device, with the charging port for the vehicle;

communicating signals from the charging port interface to the processor through the charging port;

changing the charging state of the vehicle to ready to charge.

12. The method of claim 11, further comprising:

simulating that the vehicle is being charged via the signals without charging the vehicle.

13. The method of claim 11, further comprising:

operating at least one component of the vehicle when the charging port interface is coupled to the charging port.

14. The method of claim 13, wherein the at least one component of the vehicle includes power windows, air-conditioning, power locks, opening a trunk, and a radio.

15. The method of claim 11, further comprising:

authenticating a user of the vehicle responsive to determining that an authorized key is engaged with the vehicle, wherein the charging port interface is configured to immobilize the vehicle when the authorized key is engaged with the vehicle.

16. The method of claim 15, wherein the authorized key is configured to be physically or wirelessly engaged with the vehicle.

17. The method of claim 11, wherein when the charging state of the vehicle is passive the vehicle is mobile.

18. The method of claim 17, further comprising:

changing the charging state of the vehicle from passive to ready to charge responsive to the signals being communicated from the charging port interface.

19. The method of claim 11, further comprising:

changing the charging state of the vehicle from ready to charge to passive responsive to decoupling the charging port interface from the charging port.

20. The method of claim 11, further comprising:

transmitting the signals to the processor without transmitting power signals.
