Abstract

A keyless entry system may include one or more Near Field Communication (NFC) devices. Also described herein is a keyless entry system including a NFC device and a keypad. In a particular embodiment there is provided a vehicular keyless entry system that is integrated with a vehicle trim component. Some implementations include an antenna carried by or embedded in the trim component.

First claim

The invention claimed is:

1. A vehicular keyless entry system comprising: an electronic circuit, a NFC device integrated with the electronic circuit, a door lock system electronically coupled with the electronic circuit, and a pillar capping having an outer surface defining a portion of an exterior surface of the vehicle and an inner surface, the inner surface including a mount for carrying the NFC device and the mount including a recess extending toward the outer surface, and wherein when installed on a vehicle, the NFC device is positioned behind the pillar capping, and the NFC device operates to receive an NFC signal through the pillar capping.

2. The keyless entry system of claim 1 wherein the electronic circuit is adapted to be communicated with a controller for the door lock system and the signal provided from the interface is capable of causing the electronic circuit to issue a command to the controller to change the state of a vehicle door lock.

3. The keyless entry system of claim 1 wherein the NFC device includes an NFC initiator for transmitting a NFC signal.

4. The keyless entry system of claim 1 wherein the electronic circuit is electronically coupled with the vehicle electronics system.

5. The keyless entry system of claim 1 wherein the electronic circuit includes a CAN or LIN communication device coupled with an output device for transmitting information to a vehicle electronics system.

6. The keyless entry system of claim 1 which further comprises a keypad coupled with the NFC device.

7. The keyless entry system of claim 6 wherein the keypad includes a signal generated by a nondescript pattern or entered code.

8. The keyless entry system of claim 6 wherein the door lock system includes a lock actuator that is actuated by a signal produced by a nondescript pattern entered at the key pad.

9. The keyless entry system of claim 1 which also includes an antenna communicated with at least one of the NFC device and the electronic circuit for communication of a NFC signal.

10. The keyless entry system of claim 1 wherein the recess defines a thinner section of the pillar capping with a smaller distance between the inner surface and outer surface.

11. The keyless entry system of claim 10 wherein the NFC device includes an antenna and the antenna is received within the thinner section of the pillar capping.

12. The keyless entry system of claim 1 wherein the NFC device includes an interface including an indicia that is visible through the outer surface.

13. The keyless entry system of claim 12 wherein the pillar capping includes a translucent material between the outer surface and the NFC device.

14. A vehicular keyless entry system, comprising:
a keyless entry system including an electronic circuit and an NFC device integrated with the electronic circuit, wherein the keyless entry system is electronically coupled to a door lock to unlock a vehicle door in response to receiving an NFC communication signal;
a pillar capping having an outer surface defining a portion of an exterior surface of the vehicle and an inner surface, the inner surface including a mount for carrying a portion of the keyless entry system, and
wherein when installed on a vehicle, the NFC device is positioned behind the pillar capping, and the NFC device operates to receive an NFC signal through the pillar capping and the NFC device includes an interface including an indicia that is visible through the outer surface.

15. The vehicular keyless entry system of claim 14 , wherein the NFC device is spaced between the top and bottom ends of the pillar capping when installed on a door, and between edges of the pillar capping connecting the top and bottom ends.

16. The vehicular keyless entry system of claim 14 , wherein the keyless entry system further includes an antenna carried by the capping.

17. The vehicular keyless entry system of claim 16 , wherein at least part of the antenna is at the inner surface of the capping.

18. The vehicular keyless entry system of claim 16 , wherein the antenna is contoured to match a contour of an adjacent portion of the outer surface and maintain an at least somewhat uniform distance from the outer surface along at least a majority of the antenna.

19. The vehicular keyless entry system of claim 16 , wherein the antenna is a loop type antenna made from a silver-based conductor, copper-based conductor or low resistance ink.

20. The vehicular keyless entry system of claim 14 , which also includes a cover that includes connection features adapted to cooperate with the mount of the capping to retain the cover on the capping.

21. The vehicular keyless entry system of claim 20 , wherein the cover includes openings through which pegs extending from the capping are received, and wherein the pegs may be snap-fit, glued, heat staked, welded or screwed to secure the cover to the pegs.

22. The vehicular keyless entry system of claim 14 , wherein the pillar capping includes a translucent material in front of at least a portion of the keyless entry system to allow light indicators on the keyless entry system to shine through the translucent material to on activation of the keyless entry system.

23. The vehicular keyless entry system of claim 14 , wherein the NFC device is passive, enabling one-way communication with a coupled external NFC device.

24. The vehicular keyless entry system of claim 14 , wherein the NFC device is powered, enabling two-way communication with a coupled external NFC device.
