Abstract

A user-activated, non-contact power closure member system and method of operating a closure member of a vehicle are provided. The system includes at least one sensor for sensing an object or motion. An indicator is located on the vehicle to inform the user of the appropriate location to make an activation gesture, which initiates opening of the closure member. The indicator is located adjacent the at least one sensor. The indicator also informs the user if the system is activated, in motion, and/or waiting for the activation gesture. An electronic control unit is connected to the at least one sensor and the indicator. When the object or motion is detected by the at least one sensor, the control unit notifies the user with the indicator, determines if the object or motion is the correct activation gesture, and initiates movement of the closure member.

Claims

1. A user-activated, non-contact power closure member system for operating a closure member of a vehicle, comprising:

at least one sensor for sensing at least one of an object and motion adjacent the closure member and outputting data corresponding to at least one of an object and motion;

at least one indicator disposed on the vehicle in a location indicating an appropriate location to make a correct activation gesture;

an electronic control unit coupled to said at least one sensor and said at least one indicator and configured to;

receive and process data corresponding to the at least one of the object and motion from said at least one sensor,

determine whether the data associated with the at least one of the object and motion is the correct activation gesture required to move the closure member,

initiate movement of the closure member in response to the at least one of the object and motion being the correct activation gesture, and

notify the user using said at least one indicator of the appropriate location to make the correct activation gesture and inform the user that that they are making the activation gesture in the correct location.

2. The system as set forth in claim 1, wherein said electronic control unit is further configured to receive data corresponding to the at least one of the object and motion in response to detection of a fob associated with the vehicle being located within a predetermined distance of the vehicle.

3. The system as set forth in claim 1, wherein said indicator is disposed directly adjacent said at least one sensor.

4. The system as set forth in claim 1, wherein the closure member is a rear liftgate and said indicator is disposed on a rear bumper of the vehicle below the rear liftgate.

5. The system as set forth in claim 1, wherein the closure member is a sliding door and said indicator is disposed on the vehicle below sliding door.

6. The system as set forth in claim 1, wherein said indicator is at least one of a projected image and a light.

7. The system as set forth in claim 6, wherein said indicator has a different color in an on state and in an off state.

8. The system as set forth in claim 1, wherein said at least one sensor includes a pair of sensors and one of said pair of sensors is a transmit sensor and the other is a receive sensor.

9. The system as set forth in claim 1, wherein said control unit is further configured to notify the user that said system is activated.

10. The system as set forth in claim 1, wherein said control unit is further configured to notify the user that said system detects a key fob.

11. The system as set forth in claim 1, wherein said electronic control unit includes at least one light emitting diode and is disposed within a housing.

12. The system as set forth in claim 11, further including an image cover disposed over said housing including a cutout of a graphic lit by said at least one light emitting diode.

13. A method of operating a closure member of a vehicle using a non-contact power closure member system comprising the steps of:

notifying a user of an appropriate location to make a correct activation gesture using at least one indicator disposed on the vehicle in a location indicating the appropriate location;

detecting at least one of an object and a motion located adjacent the closure member using at least one sensor;

determining whether data associated with at least one of the object and the motion is the correct activation gesture which is required to initiate opening of the closure member; and

initiating movement of the closure member in response to determining that the data associated with the at least one of the object and the motion is the correct activation gesture.

14. The method as set forth in claim 13, further including the step of registering a false signal in response to determining that the data associated with the at least one of the object and the motion is not the correct activation gesture.

15. The method as set forth in claim 13, further including the step of notifying the user in response to the system beginning powered system activation.

16. The method as set forth in claim 13, further including the step of notifying the user that the system is activated.

17. The method as set forth in claim 13, further including the step of notifying the user that the system detects a key fob.

18. The method as set forth in claim 13, further including the step of notifying the user that the closure member is in motion.

19. The method as set forth in claim 13, further including the step of notifying the user in response to the system waiting for the activation gesture.

20. The method as set forth in claim 13, wherein the step of detecting at least one of the object and the motion located adjacent the closure member using at least one sensor includes detecting at least one of the object and the motion located adjacent the closure member using at least one sensor in response to a key fob associated with the vehicle being within a predetermined distance of the vehicle.
