Abstract

A sunroof panel and sunshade assembly system includes a moveable sunroof panel operable to selectively move to a first closed position within a sunroof opening of a vehicle and a sunshade operable to selectively move to a second closed position within the sunroof opening. The sunshade includes a leading-edge portion and a spring force displacement member within the leading-edge portion of the sunshade, wherein the spring force displacement member is operable to deform when the sunshade contacts an obstruction while the sunshade is moving. The system further includes an electric machine providing motive force to the sunshade and a computerized sunroof panel and sunshade controller. The controller operates programming to monitor operation of the electric machine, determine a presence of the obstruction based upon the monitored operation, and command the electric machine to stop and reverse the sunshade based upon the determined presence.

First claim

What is claimed is:

1. A sunroof panel and sunshade assembly system, comprising:
a moveable sunroof panel operable to selectively move to a first closed position within a sunroof opening of a vehicle;
a sunshade operable to selectively move to a second closed position within the sunroof opening, the sunshade including:
a leading-edge portion disposed along an edge of the sunshade in a direction in which the sunshade moves to reach the second closed position;
a spring force displacement member within the leading-edge portion of the sunshade, wherein the spring force displacement member is operable to deform when the sunshade contacts an obstruction while the sunshade is moving to the second closed position; and

an electric machine providing motive force to the sunshade; and
a computerized sunroof panel and sunshade controller, operating programming to:
monitor operation of the electric machine;
determine a presence of the obstruction during the monitored operation; and
command the electric machine to stop and reverse the sunshade based upon the determined presence.

2. The sunroof panel and sunshade assembly system of claim 1 , wherein the computerized sunroof panel and sunshade controller further operates programming to:
monitor activation of a remote command to close the sunshade; and
command initiation of a closure event of the sunshade based upon the monitored activation.

3. The sunroof panel and sunshade assembly system of claim 2 , wherein monitoring the activation of the remote command includes receiving an activation command from a key fob device.

4. The sunroof panel and sunshade assembly system of claim 2 , wherein monitoring the activation of the remote command includes receiving an activation command from a smartphone device.

5. The sunroof panel and sunshade assembly system of claim 1 , wherein the computerized sunroof panel and sunshade controller further operates programming to:
monitor data from a rain sensor device; and
command initiation of a closure event of the sunshade based upon the data from the rain sensor device.

6. The sunroof panel and sunshade assembly system of claim 1 , wherein the spring force displacement member within the leading-edge portion of the sunshade includes a coil spring operable to compress as the sunshade contacts the obstruction.

7. The sunroof panel and sunshade assembly system of claim 1 , wherein the spring force displacement member within the leading-edge portion of the sunshade includes a flex arm operable to bend as the sunshade contacts the obstruction.

8. The sunroof panel and sunshade assembly system of claim 1 , wherein the sunshade includes a plastic tray; and
wherein the spring force displacement member within the leading-edge portion of the sunshade includes accordion-shaped bend in the plastic tray operable to bend as the sunshade contacts the obstruction.

9. The sunroof panel and sunshade assembly system of claim 1 , wherein the computerized sunroof panel and sunshade controller further operates programming to:
command the electric machine providing motive force to the sunshade to begin moving to the second closed position; and
command an electric machine providing motive force to the sunroof panel to begin moving to the first closed position with a time lag relative to the electric machine providing motive force to the sunshade.

10. The sunroof panel and sunshade assembly system of claim 1 , further comprising a compliant body structure interface providing a surface for the sunshade to seal against in the second closed position and including a body structure spring force member operable to deform when the sunshade contacts the obstruction while the sunshade is moving to the second closed position.

11. A sunroof panel and sunshade assembly system, comprising:
a moveable sunroof panel operable to selectively move to a first closed position within a sunroof opening of a vehicle;
a sunshade operable to selectively move to a second closed position within the sunroof opening, the sunshade including:
a leading-edge portion disposed along an edge of the sunshade in a direction in which the sunshade moves to reach the second closed position;
a spring force displacement member within the leading-edge portion of the sunshade, wherein the spring force displacement member is operable to deform when the sunshade contacts an obstruction while the sunshade is moving to the second closed position; and

an electric machine providing motive force to the sunshade; and
a computerized sunroof panel and sunshade controller, operating programming to:
monitor operation of the electric machine;
determine whether the obstruction is present within the sunroof opening based upon the monitored operation;
when the obstruction is determined to be present, command the electric machine to stop and reverse the sunshade;
when the obstruction is not determined to be present,
determine successful closure of the sunshade based upon the monitored operation; and
command the sunroof panel to move to the first closed position based upon the determined successful closure.

12. The sunroof panel and sunshade assembly system of claim 11 , wherein the computerized sunroof panel and sunshade controller further operates programming to:
monitor activation of a remote command to close the sunshade; and
command initiation of a closure event of the sunshade based upon the monitored activation.

13. The sunroof panel and sunshade assembly system of claim 12 , wherein monitoring the activation of the remote command includes receiving an activation command from a key fob device.

14. The sunroof panel and sunshade assembly system of claim 12 , wherein monitoring the activation of the remote command includes receiving an activation command from a smartphone device.

15. The sunroof panel and sunshade assembly system of claim 11 , wherein the computerized sunroof panel and sunshade controller further operates programming to:
monitor data from a rain sensor device; and
command initiation of a closure event of the sunshade based upon the data from the rain sensor device.

16. The sunroof panel and sunshade assembly system of claim 11 , further comprising a compliant body structure interface providing a surface for the sunshade to seal against in the second closed position and including a body structure spring force member operable to deform when the sunshade contacts the obstruction while the sunshade is moving to the second closed position.

17. A method for control of a vehicle sunroof panel and sunshade assembly, comprising:
operating a closure event of a sunshade of the vehicle sunroof panel and sunshade assembly, including using an electric machine to provide motive force to move the sunshade toward a closed position and wherein the sunshade includes a leading-edge portion including a spring force displacement member operable to deform when the sunshade contacts an obstruction; and
within a computerized sunroof panel and sunshade controller, operating programming to:
monitor operation of the electric machine;
determine a presence of the obstruction based upon the monitored operation; and
command the electric machine to stop and reverse the sunshade based upon the determined presence.

18. The method of claim 17 , further comprising:
monitoring activation of a remote command to close the sunshade via the controller; and
commanding initiation of the closure event of the sunshade via the controller based upon the monitored activation.

19. The method of claim 17 , further comprisi
