Abstract

Methods and systems for adjusting a trailer attached to a vehicle. The system includes a hitch of the vehicle located on a track along a rear end of the vehicle and configured to couple the vehicle to the trailer and move along the track. The system also includes one or more actuators coupled to the hitch and configured to move the hitch along the track. The system also includes an electronic control unit (ECU) configured to instruct the one or more actuators to move the hitch along the track.

First claim

What is claimed is:

1. A system for adjusting a trailer attached to a vehicle, the system comprising:
a hitch located on a track along a rear end of the vehicle and configured to couple the vehicle to the trailer and move along the track;
one or more actuators coupled to the hitch and configured to move the hitch along the track;
one or more rear corner sensors configured to detect sensor data including information related to proximity of the trailer to one or more corresponding corners of the vehicle; and
an electronic control unit (ECU) coupled to the one or more actuators and the one or more rear corner sensors and configured to cause the one or more actuators to move the hitch along the track based on the sensor data.

2. The system of claim 1 , further comprising one or more sensors configured to detect additional sensor data indicating a location and an orientation of the trailer relative to the vehicle, and
wherein the ECU is further configured to determine an ideal hitch location based on the additional sensor data and cause the one or more actuators to move the hitch to the ideal hitch location.

3. The system of claim 2 , wherein the one or more sensors include a rear-view camera configured to detect image data of an environment behind the vehicle.

4. The system of claim 2 , wherein the one or more sensors include one or more rear parking clearance sensors configured to detect proximity of the trailer to the rear end of the vehicle.

5. The system of claim 2 , wherein the one or more sensors include an angle detection sensor configured to detect an angle of the trailer relative to the vehicle.

6. The system of claim 2 , further comprising a vehicle speed sensor configured to detect a vehicle speed, and
wherein the ECU is further configured to determine the ideal hitch location based on the additional sensor data and the vehicle speed.

7. The system of claim 2 , further comprising a location sensor configured to detect location data associated with the vehicle, and
wherein the ECU is further configured to determine the ideal hitch location based on the additional sensor data and the location data.

8. The system of claim 1 , wherein the one or more actuators are configured to move the hitch along the track using a rail parallel to the track and having threads.

9. The system of claim 1 , wherein the one or more actuators are configured to move the hitch along the track using a pneumatic or hydraulic cylinder.

10. The system of claim 1 , wherein the one or more actuators are configured to move the hitch along the track using a rail parallel to the track and having teeth for engaging a gear coupled to the hitch.

11. A vehicle coupled to a trailer, the vehicle comprising:
a hitch located on a track along a rear end of the vehicle and configured to couple the vehicle to the trailer and move along the track;
one or more actuators coupled to the hitch and configured to move the hitch along the track;
one or more rear corner sensors configured to detect sensor data including information related to proximity of the trailer to one or more corresponding corners of the vehicle; and
an electronic control unit (ECU) coupled to the one or more actuators and the one or more rear corner sensors and configured to cause the one or more actuators to move the hitch along the track based on the sensor data.

12. The vehicle of claim 11 , further comprising one or more sensors configured to detect additional sensor data indicating a location and an orientation of the trailer relative to the vehicle, and
wherein the ECU is further configured to determine an ideal hitch location based on the additional sensor data and cause the one or more actuators to move the hitch to the ideal hitch location.

13. The vehicle of claim 12 , wherein the one or more sensors include at least one of:
a rear-view camera configured to detect image data of an environment behind the vehicle,
one or more rear parking clearance sensors configured to detect proximity of the trailer to the rear end of the vehicle, or
an angle detection sensor configured to detect an angle of the trailer relative to the vehicle.

14. The vehicle of claim 12 , further comprising a vehicle speed sensor configured to detect a vehicle speed, and
wherein the ECU is further configured to determine the ideal hitch location based on the additional sensor data and the vehicle speed.

15. The vehicle of claim 12 , further comprising a location sensor configured to detect location data associated with the vehicle, and
wherein the ECU is further configured to determine the ideal hitch location based on the additional sensor data and the location data.

16. The vehicle of claim 11 , wherein the one or more actuators are configured to move the hitch along the track using a rail parallel to the track and having threads, move the hitch along the track using a pneumatic or hydraulic cylinder, or move the hitch along the track using a rail parallel to the track and having teeth for engaging a gear coupled to the hitch.

17. A method for adjusting a trailer attached to a vehicle, the method comprising:
detecting, by one or more sensors including at least one rear parking clearance sensor configured to detect information related to proximity of the trailer to a rear end of the vehicle, sensor data indicating a location and an orientation of the trailer relative to the vehicle;
determining, by an electronic control unit (ECU) coupled to the one or more sensors and one or more actuators and based on the sensor data, an ideal hitch location of a hitch located on a track along a rear end of the vehicle and configured to couple the vehicle to the trailer and move along the track; and
causing, by the ECU, the one or more actuators to move the hitch to the ideal hitch location.

18. The method of claim 17 , further comprising:
identifying, by the ECU and based on the sensor data, potential contact between the vehicle and the trailer; and
determining, by the ECU, a hitch movement to avoid the potential contact between the vehicle and the trailer, and
wherein determining the ideal hitch location includes determining the ideal hitch location based on the hitch movement to avoid the potential contact between the vehicle and the trailer.

19. The method of claim 17 , further comprising:
identifying, by the ECU, one or more lines associated with a parking space; and
determining, by the ECU, a trailer movement to align the trailer with the one or more lines associated with the parking space, and
wherein determining the ideal hitch location includes determining the ideal hitch location based on the trailer movement to align the trailer with the one or more lines associated with the parking space.
