Abstract

A pick-up truck includes a pick-up bed, a tailgate connected to the pick-up bed, a motor configured to move the tailgate along a path, a camera, and processors. The processors stop the tailgate while the tailgate is automatically moving in response to detecting, via the camera, any object within the path.

First claim

What is claimed is:

1. A pick-up truck comprising:
a pick-up bed;
a power tailgate connected to the pick-up bed;
a motor configured to move the power tailgate along a path;
a camera;
processors configured to, while the power tailgate is automatically moving, responsive to detecting, via the camera, any object within the path, stop the power tailgate;
walls connected to edges of the pick-up bed, a portion of the walls defining a truck tail, the truck tail configured to engage the power tailgate when the power tailgate is in a closed position; and
tactile sensors disposed on the truck tail, wherein the processors are further configured to, responsive to the power tailgate being in the closed position and responsive to less than all of the tactile sensors being activated, generate a warning command.

2. The pick-up truck of claim 1 , further comprising sensors, wherein the processors are further configured to, while the power tailgate is automatically moving, responsive to detecting, via the sensors, a level of force exerted on the power tailgate satisfying a threshold, stop the power tailgate.

3. The pick-up truck of claim 2 , further comprising a pitch sensor, wherein the processors are further configured to: responsive to detecting, via the pitch sensor, an angle of a pitch of the pick-up truck satisfying a pitch angle, adjust the threshold.

4. The pick-up truck of claim 2 , further comprising a pitch sensor, wherein the processors are further configured to: responsive to detecting, via the pitch sensor, that the pick-up truck is positioned in an incline, increase the threshold.

5. The pick-up truck of claim 2 , further comprising a pitch sensor, wherein the processors are further configured to: responsive to detecting, via the pitch sensor, that the pick-up truck is positioned in a decline, decrease the threshold.

6. The pick-up truck of claim 1 , wherein the processors are further configured to learn a range of degrees at which the power tailgate is able to move.

7. The pick-up truck of claim 1 , further comprising side mirror cameras, wherein the processors are further configured to, while the power tailgate is automatically moving and responsive to a view of the camera being obstructed:
monitor, via the side mirror cameras, an area surrounding the power tailgate; and
responsive to detecting, via the side mirror cameras, any object within the area, stop the power tailgate.

8. The pick-up truck of claim 1 , further comprising a speaker, wherein the processors are further configured to, responsive to detecting, via the camera, any object within the path, provide an audible warning though the speaker.

9. The pick-up truck of claim 1 , wherein a mobile device is wirelessly coupled to the processors, and wherein the processors are further configured to, responsive to detecting, via the camera, any object within the path, cause the mobile device to provide a warning to a user.

10. The pick-up truck of claim 1 , further comprising:
an arm connecting the power tailgate and the pick-up bed, wherein the arm is one of a group consisting: a hydraulic device and a pneumatic device, and wherein the motor is further configured to drive the arm to move the power tailgate along the path; and
pressure sensors configured to measure pressure applied to the arm, wherein the processors are further configured to while the power tailgate is automatically moving, responsive to detecting, via the pressure sensors, a level of pressure satisfying a threshold, stop the power tailgate.

11. A method of operating a power tailgate of a pick-up truck, the method comprising:
automatically moving the power tailgate along a path via a motor; and
while the power tailgate is automatically moving, responsive to detecting, via a camera, any object within the path, stopping the power tailgate while the power tailgate is automatically moving and responsive to a view of the camera being obstructed:
monitoring, via side mirror cameras, an area surrounding the power tailgate; and
responsive to detecting, via the side mirror cameras, any object within the area, stopping the power tailgate.

12. The method of claim 11 , further comprising: while the power tailgate is automatically moving, responsive to detecting, via sensors, a level of force exerted on the power tailgate satisfying a threshold, stop the power tailgate.

13. The method of claim 12 , further comprising, responsive to detecting, via a pitch sensor, an angle of a pitch of the pick-up truck satisfying a pitch angle, adjusting the threshold.

14. The method of claim 12 , further comprising, responsive to detecting, via a pitch sensor, that the pick-up truck is positioned in an incline, increasing the threshold.

15. The method of claim 12 , further comprising, responsive to detecting, via a pitch sensor, that the pick-up truck is positioned in a decline, decreasing the threshold.

16. The method of claim 11 , further comprising:
responsive to the power tailgate being in a closed position, activating tactile sensors; and
responsive to the power tailgate being in the closed position and responsive to less than all of tactile sensors being activated, generating a warning command.

17. The method of claim 11 , further comprising learning a range of degrees at which the power tailgate is able to move.

18. The method of claim 11 , further comprising responsive to detecting, via the camera, any object within the path, providing an audible warning though a speaker.

19. The method of claim 11 , further comprising, responsive to detecting, via the camera, any object within the path, causing a mobile device wirelessly coupled to the pick-up truck to provide a warning to a user.

20. A non-transitory, computer readable medium storing instructions that are executable by at least one processor to perform operations comprising:
causing a power tailgate to automatically move along a path via a motor;
while the power tailgate is automatically moving, responsive to detecting, via a camera, any object within the path, stopping the power tailgate; and
while the power tailgate is automatically moving and responsive to a view of the camera being obstructed:
monitoring, via side mirror cameras, an area surrounding the power tailgate; and
responsive to detecting, via the side mirror cameras, any object within the area, stopping the power tailgate.
