Abstract

A method for identifying a trailer connection for a vehicle includes storing a plurality of connection configurations as saved configurations. The connection configurations identify a hitch compatibility of a coupler of a trailer to a hitch assembly. The method further comprises capturing image data depicting the hitch assembly and processing the image data. Based on the processing of the image data, the method further identifies a detected hitch configuration of the hitch assembly as a first hitch configuration of the saved configurations.

Claims (53)

1. A method for identifying a trailer connection for a vehicle, the method comprising:

storing a plurality of connection configurations as saved configurations, wherein the connection configurations identify a compatibility of a coupler of a trailer to a hitch assembly;

identifying a hitch configuration of the hitch assembly as a first hitch configuration of the saved configurations, wherein the first hitch configuration comprises a hitch ball diameter of a hitch ball of the hitch assembly;

capturing first image data depicting the trailer;

processing the first image data and identifying a detected coupler configuration of the coupler of the trailer as a second configuration of the saved configurations;

comparing the first configuration of the hitch assembly to the second configuration of the coupler;

identifying the compatibility of the coupler to the hitch ball diameter of the hitch assembly based on the comparison; and

controlling a navigation operation of the vehicle based on the first hitch configuration of the hitch assembly in response to the compatibility.

2. The method according to claim 1 , further comprising:

receiving a confirmation of the first hitch configuration via a user interface.

3. The method according to claim 1 , further comprising:

displaying the first hitch configuration on a display identifying the detected hitch configuration.

4. The method according to claim 1 , further comprising:

identifying a location of a coupler of a trailer in first image data; and

controlling a navigation of the vehicle based on the first hitch configuration of the hitch assembly and the location of the coupler.

5. The method according to claim 1 , wherein the saved configurations comprise a position of the hitch ball relative to the vehicle.

6. The method according to claim 5 , further comprising:

processing a path derivation routine identifying a navigation path of the vehicle aligning the hitch ball with the coupler based on the position of the hitch ball.

7. The method according to claim 1 , wherein the coupler configuration comprises a connection diameter of the coupler.

8. A vehicle system, comprising:

a hitch assembly mounted on a vehicle;

an imaging system configured to capture image data comprising the hitch assembly;

a user interface comprising a display; and

a controller that:

identifies a coupler of a trailer based on the image data;

accesses a coupler configuration of the trailer in response to the identification of the trailer;

identifies a compatibility of the coupler configuration to a hitch ball diameter of the hitch assembly based on the coupler configuration; and

controls an automated navigation operation of the vehicle based on the configuration for the hitch assembly.

9. The system according to claim 8 , wherein the controller further:

identifies the hitch assembly based on the image data;

accesses a hitch configuration of the hitch assembly in response to the identification displays the hitch configuration on the display; and

receives a selection of the hitch configuration.

10. The system according to claim 9 , wherein the controller further:

displays the coupler configuration on the display; and

receives a selection of the coupler configuration.

11. The system according to claim 10 , wherein the selection of the coupler configuration is a confirmation that the detected coupler is correctly identified.

12. The system according to claim 8 , wherein the controller further:

in response to a positive determination of the connection compatibility, controls the automated navigation operation.

13. The system according to claim 8 , wherein the controller further:

in response to a negative determination of the connection compatibility, outputs an instruction to adjust at least one of the hitch configuration and the coupler configuration.

14. A method for identifying a trailer connection for a vehicle, the method comprising:

storing a plurality of connection configurations as saved configurations, wherein the connection configurations identify a hitch compatibility of a coupler of a trailer to a hitch assembly;

capturing first image data of the hitch assembly;

processing the first image data and identifying a detected hitch configuration of the hitch assembly as a first hitch configuration of the saved configurations, wherein the first hitch configuration comprises a hitch ball diameter of a hitch ball of the hitch assembly;

capturing second image data of the trailer;

processing the second image data and identifying a detected trailer configuration of a coupler of the trailer as a second configuration of the saved configurations;

comparing the first configuration of the hitch assembly to the second configuration of the coupler;

identifying a compatibility of the coupler to the hitch ball diameter of the hitch assembly based on the comparison; and

controlling a navigation operation of the vehicle based on the compatibility.

15. The method according to claim 1 , further comprising:

capturing second image data depicting the hitch assembly;

processing the second image data and identifying the hitch configuration of the hitch assembly as the first hitch configuration of the saved configurations.

16. The system according to claim 9 , wherein the selection of the hitch configuration is a confirmation that the detected hitch assembly is correctly identified.
