Abstract

Systems and methods are provided for a vehicle roof closure that can prevent pinching of obstructions within a roof opening. Example vehicles include a roof having an opening, a panel disposed adjacent to the opening and moveable by a first motor, a shade disposed below the panel and moveable by a second motor having a lower output than the first motor, and a controller configured to close the shade before closing the panel during a close panel operation, and stop the shade if an obstruction is detected within the opening. Example methods include upon receiving a command to close a panel over an opening, causing a shade motor to start closing a shade disposed below the panel by unrolling the shade; stopping the shade motor upon detection of an obstruction within the opening; and causing a panel motor to start closing the panel upon receiving a shade closed signal.

First claim

The invention claimed is:

1. A vehicle comprising:
a panel disposed adjacent to a roof opening and moveable by a first motor;
a shade disposed below the panel and moveable by a second motor having a low harmless impact output lower than the first motor; and
a controller configured to:
during a close panel operation, close the shade before closing the panel, and
stop the shade if an obstruction is detected within the opening.

2. The vehicle of claim 1 , wherein closing the shade includes unrolling the shade to cover the opening.

3. The vehicle of claim 1 , wherein the controller is further configured to open the shade after stopping the shade.

4. The vehicle of claim 1 , wherein the controller is further configured to retrieve a vehicle occupancy status, and initiate closing of the shade only if the vehicle occupancy status is positive.

5. The vehicle of claim 1 , further including an occupancy sensor configured to detect an occupant in close proximity to the vehicle and to determine a vehicle occupancy status based thereon.

6. The vehicle of claim 1 , wherein the shade includes a flexible fabric.

7. The vehicle of claim 1 , further comprising a pair of opposing side rails disposed adjacent to the opening for slidably receiving respective sides of the rollable shade.

8. The vehicle of claim 1 , wherein the close panel operation is initiated upon receiving a command from an actuator configured to enable remote user control of the panel.

9. The vehicle of claim 1 , wherein the close panel operation is automatically initiated by the controller upon receiving a pre-designated indication.

10. The vehicle of claim 1 , further comprising an obstruction detector positioned relative to a front edge of the shade.

11. The vehicle of claim 10 , wherein the obstruction detector is a pressure sensor disposed adjacent to a front end of the opening, the front end receiving the front edge of the shade.

12. The vehicle of claim 10 , wherein the obstruction detector is a capacitive sensor configured to detect an obstruction between the front edge of the shade and a front end of the opening.

13. A method of controlling a vehicle roof closure, comprising:
upon receiving, at a processor, a command to close a panel over an opening, causing a shade motor to start closing a shade below the panel by unrolling the shade only if an occupancy status is positive;
stopping the shade motor upon detection of an obstruction within the opening; and
upon receiving a shade closed signal, causing a panel motor to start closing the panel.

14. The method of claim 13 , further comprising causing the shade motor to open the shade after stopping the shade motor.

15. The method of claim 13 , wherein the shade includes a flexible fabric.

16. The method of claim 13 , wherein the command is received from an actuator configured to enable remote user control of the panel.

17. The method of claim 13 , wherein the command is included in a command to automatically close the panel.

18. The method of claim 13 , wherein the panel motor has a higher output than the shade motor.
