Method and apparatus for preventing tailgate collision with hitch accessory
A method and apparatus that prevent a collision with a hitch accessory are provided. The method includes: detecting an input to open a gate or detecting a gate opening motion, determining whether hitch accessory is present in a path of the gate opening motion, and in response to determining that the hitch accessory is absent from the path, opening the gate.
1. A method that prevents a collision with a hitch accessory, the method comprising:
detecting, by a processor, an input to open a gate or detecting an opening motion of a gate;
in response to detecting the input or detecting the opening motion of the gate, determining, by a processor, whether hitch accessory is present in an area of the opening motion of the gate; and
in response to determining that the hitch accessory is present in the path, inhibiting, by a processor, the opening motion of the gate by locking the gate, stopping an actuator configured to move the gate, or reversing an actuator configured to move the gate,
wherein the detecting input to open a gate comprises detecting actuation of a gate latch,
wherein the detecting the opening motion of the gate comprises detecting movement of the gate via a camera capturing an image of the gate or a sensor configured to sense movement of a hinge of the gate, and
wherein the determining whether the hitch accessory is present in the area of the opening motion of the gate comprises calculating coordinates of the hitch accessory from an image of the hitch accessory captured by the camera.
2. The method of claim 1 , wherein the determining whether the hitch accessory is present in the area of the opening motion of the gate further comprises determining whether the calculated coordinates intersect with preset coordinates corresponding the area of the opening motion of the gate.
3. The method of claim 2 , wherein the calculated coordinates and the preset coordinates are 3 axis coordinates corresponding to a real world space.
4. The method of claim 1 , wherein the determining whether the hitch accessory is present in the area of the opening motion of the gate further comprises calculating the area of the opening motion of the gate from a plurality of images of the gate captured during the opening motion of the gate, and determining whether the calculated coordinates intersect the calculated area of the opening motion of the gate.
5. The method of claim 1 , further comprising:
in response to determining that the hitch accessory is present in the path, outputting a notification indicating that the opening motion of the gate is inhibited or that the hitch accessory is in the path of the gate onto a display.
6. The method of claim 1 , wherein the hitch accessory comprises a hitch receiver including a ball mount.
7. An apparatus prevents a collision with a hitch accessory, the apparatus comprising:
a camera configured to capture an image of a hitch accessory and a gate;
at least one memory comprising computer executable instructions; and
at least one processor configured to read and execute the computer executable instructions, the computer executable instructions causing the at least one processor to:
detect an input to open the gate by detecting actuation of a gate latch or detect an opening motion of the gate from the image captured by the camera;
in response to detecting the input or detecting the opening motion, determine whether the hitch accessory is present in an area of the opening motion of the gate by calculating coordinates of the hitch accessory from the image of the hitch accessory captured by the camera; and
in response to determining that the hitch accessory is present in the path, inhibit the opening motion of the gate by locking the gate, stopping an actuator configured to move the gate, or reversing an actuator configured to move the gate,
wherein the detecting the opening motion of the gate further comprises detecting movement of the gate via a sensor configured to sense movement of a hinge of the gate.
8. The apparatus of claim 7 , wherein the computer executable instructions cause the at least one processor to determine whether the hitch accessory is present in the area of the opening motion of the gate by determining whether the calculated coordinates intersect with preset coordinates corresponding the area of the opening motion of the gate.
9. The apparatus of claim 8 , wherein the calculated coordinates and the preset coordinates are 3 axis coordinates corresponding to a real world space.
10. The apparatus of claim 7 , wherein the computer executable instructions cause the at least one processor to determine whether the hitch accessory is present in the area of the opening motion of the gate by calculating the area of the opening motion of the gate from a plurality of images of the gate captured during the opening motion of the gate and determining whether the calculated coordinates intersect the calculated area of the opening motion of the gate.
11. The apparatus of claim 7 , wherein the computer executable instructions cause the at least one processor to output a notification indicating that the opening motion of the gate is inhibited or that the hitch accessory is in the path of the gate to a display in response to determining that the hitch accessory is present in the path.
