Vehicle and system having trailer coupler connection detection
A vehicle is provided with a trailer hitch, a camera oriented to capture images of the trailer hitch, and a controller processing the captured images, detecting a trailer coupler coupled to the trailer hitch, determining a locked or unlocked state of the hitch coupler by comparing the captured images to known trailer coupler images, and generating an output indicative of the determined state of the trailer coupler.
1. A vehicle comprising:
a trailer hitch;
a camera oriented to capture images of the trailer hitch; and
a controller processing the captured images, detecting a trailer coupler coupled to the trailer hitch, determining a locked or unlocked state of the hitch coupler by comparing the captured images to known trailer coupler images, and generating an output indicative of the determined state of the trailer coupler, wherein the known images are leaded images, and wherein the learned images are earned by the controller during a calibration procedure by saving images of the hitch coupler in the locked and unlocked states.
2. The vehicle of claim 1 , wherein the saved images are stored in memory.
3. The vehicle of claim 1 , wherein the trailer hitch comprises a tow ball.
4. The vehicle of claim 1 further comprising a display for displaying the output as a warning to a driver of the vehicle.
5. A vehicle comprising:
a trailer hitch;
a camera oriented to capture images of the trailer hitch; and
a controller processing the captured images, detecting a trailer coupler coupled to the trailer hitch, determining a locked or unlocked state of the hitch coupler by comparing the captured images to known trailer coupler images, and generating an output indicative of the determined stat o the trailer coupler, wherein the controller further detects the vehicle is in a trailer mode before generating the output.
6. The vehicle of claim 5 , wherein the controller detects the trailer mode when a driving task is initiated.
7. The vehicle of claim 6 , wherein the initiation of the driving task comprises a vehicle transmission shifted out of park.
8. The vehicle of claim 5 , wherein the controller detects the trailer mode by a user input.
9. A system for detecting a state of a trailer coupler connected to a vehicle trailer hitch on a vehicle, comprising:
a camera oriented to capture images of the vehicle trailer hitch; and
a controller processing the captured images, detecting the trailer coupler coupled to the vehicle trailer hitch, determining a locked or unlocked state of the trailer coupler by comparing the captured images to known trailer coupler images, and generating an output indicative of the determined state of the trailer coupler, wherein the known images are learned images, and wherein the learned images are learned by the controller during a calibration procedure by comparing images of the hitch coupler in the locked and unlocked states.
10. The system of claim 9 , wherein the vehicle trailer hitch comprises a tow ball.
11. The system of claim 9 further comprising a display for displaying the output as a warning to a driver of the vehicle.
12. The system of claim 9 , wherein the controller further detects the vehicle is in a trailer mode before generating the output.
13. The system of claim 12 , wherein the controller detects the trailer mode when a driving task is initiated.
14. The vehicle of claim 13 , wherein the initiation of a driving task comprises a vehicle transmission shifted out of park.
15. The system of claim 12 , wherein the controller detects the trailer mode by a user input.
