Abstract

An authentication-based multi-stage powering scheme is disclosed. An initial authentication stage can include low-power components to sense user initialization signal and authenticate the user. When the user is authenticated the vehicle system can be initialized and one or more subsequent sensing components can be powered up and activated. When the one or more subsequent sensing components receives further user information, such as user proximity to the vehicle, subsequent parts of the vehicle system can be powered up and activated to allow user access to the vehicle.

Claims

1. An electric vehicle comprising:

an initialization signal detector;

initial authentication circuitry; and

one or more subsequent signal detectors.

2. The electric vehicle of claim 1, wherein the initial authentication circuitry is activated by the initialization signal detector.

3. The electric vehicle of claim 2, wherein a subsequent signal detector is activated by the initial authentication circuitry.

4. The electric vehicle of claim 1 further comprising access authorization circuitry activated by a subsequent signal detector.

5. The electric vehicle of claim 1 further comprising operation authorization circuitry activated by a subsequent signal detector.

6. The electric vehicle of claim 1 further comprising authorization circuitry configured to authorize one or more vehicle functions, the authorization circuitry activated by a subsequent signal detector.

7. The electric vehicle of claim 1, wherein the initialization signal detector is configured to detect at least one of a radio frequency signal and an infrared signal.

8. A method for enabling authorized use of a vehicle comprising:

receiving an initialization signal;

initializing the vehicle upon receiving the initialization signal;

receiving a subsequent signal; and

authorizing access to the vehicle upon receiving the subsequent signal.

9. The method of claim 8 further comprising authorizing operation of the vehicle.

10. The method of claim 9 further comprising receiving a third signal, wherein authorizing operation of the vehicle occurs based at least in part on receiving the third signal.

11. The method of claim 9, wherein the operation of the vehicle comprises activation of a powertrain of the vehicle.

12. The method of claim 8 further comprising authorizing one or more functions of the vehicle.

13. The method of claim 12 further comprising receiving a third signal, wherein authorizing one or more functions of the vehicle occurs based at least in part on receiving the third signal.

14. The method of claim 8, wherein the initialization signal and the subsequent signal comprise at least one of a short field radio frequency signal and an infrared signal.

15. A system comprising:

a portable interface; and

an electric vehicle comprising;

an initialization signal detector configured to detect the portable interface;

initial authentication circuitry; and

one or more subsequent signal detectors.

16. The system of claim 15, wherein a subsequent signal detector is activated by the initial authentication circuitry.

17. The system of claim 15, wherein the electric vehicle further comprises access authorization circuitry.

18. The system of claim 15, wherein the portable interface comprises at least one of a key fob and a personal electronic device.

19. The system of claim 15, wherein the portable interface is configured to communicate with the initialization signal detector by at least one of short field radio frequency, passive radio frequency, and infrared.
