Abstract

A method for operating a closure panel of a vehicle, comprising: using a processor, determining whether a first proximity sensor and a second proximity sensor located on a periphery of the vehicle have been sequentially activated to indicate an object moving across the first proximity sensor and the second proximity sensor; and, controlling the closure panel to open or close when the first proximity sensor and the second proximity sensor have been sequentially activated.

Claims

1. A method of operating a closure panel of a vehicle, comprising:

locating a sensor module on a periphery of a vehicle having at least one proximity sensor;

authenticating a fob with an authentication system;

determining whether the at least one proximity sensor has been activated after the fob has been authenticated without requirement of a waving gesture by a user;

providing visual feedback to the user to indicate activation of the at least one proximity sensor; and

controlling the closure panel to open or close in response to activation of the at least one proximity sensor as well as authentication of the fob.

2. The method of claim 1, wherein the sensor module is located on a side of the vehicle adjacent to a rear wheel-well such that the user standing beside the vehicle activates the at least one proximity sensor without the requirement to wave a foot within the wheel-well or under the vehicle.

3. The method of claim 2, further comprising locating the sensor module such that the at least one proximity sensor is horizontally oriented along the side of the vehicle between the rear wheel-well and a rear end portion of the vehicle.

4. The method of claim 2, further comprising locating the sensor module such that the at least one proximity sensor is vertically oriented along the side of the vehicle rearward of the rear wheel-well.

5. The method of claim 2, wherein the step of providing visual feedback to indicate activation of the at least one proximity sensor includes flashing at least one taillight of the vehicle.

6. The method of claim 2, wherein the sensor module includes a first proximity sensor and a second proximity sensor, and wherein the first and second proximity sensors are activated after authentication of the fob without requirement of the waving gesture of the user'"'"'s foot.

7. The method of claim 6, further comprising:

using a processor to determine whether the first and second proximity sensors have been activated; and

controlling the closure panel to open or close when both the first and second proximity sensors have been activated.

8. The method of claim 7, further comprising:

locating the first proximity sensor and the second proximity sensor in a horizontally spaced-apart orientation along the side periphery of the vehicle.

9. The method of claim 6, wherein the first proximity sensor and the second proximity sensor are elongate capacitive proximity sensors.

10. The method of claim 6, wherein the first proximity sensor and the second proximity sensor are vertically oriented.

11. The method of claim 6, wherein each of the first proximity sensor and the second proximity sensor has a respective horizontal portion extending along or toward an underside of the vehicle.

12. The method of claim 6, wherein the first proximity sensor and the second proximity sensor are mounted or formed on a printed circuit board.

13. The method of claim 6, further comprising:

controlling the closure panel to stop moving when the first proximity sensor and the second proximity sensor are activated simultaneously while the closure panel is moving.

14. The method of claim 13, wherein the determining of the order of activation of the first proximity sensor and the second proximity sensor further comprises comparing respective occurrences of a capacitive signal level peak magnitude for the first proximity sensor and the second proximity sensor.

15. The method of claim 6, wherein authentication of the fob with the authentication system further comprises monitoring an antenna located on the vehicle to determine whether the fob is within a predetermined distance from the vehicle.

16. The method of claim 15, wherein the determination of whether the first proximity sensor and the second proximity sensor located on the side periphery of the vehicle have been activated is performed when the fob is within the predetermined distance and has been authenticated.

17. The method of claim 6, wherein the side periphery of the vehicle is at least one of the side of the vehicle and a rear corner of the vehicle.

18. The method of claim 6, wherein the first proximity sensor and the second proximity sensor are mounted in a lens of a taillight or a headlight of the vehicle.

19. The method of claim 6, wherein the first proximity sensor and the second proximity sensor are mounted in a rear bumper of the vehicle.

20. The method of claim 6, wherein the first proximity sensor and the second proximity sensor are positioned at or on either side of a rear corner of the periphery of the vehicle.
