A trailer type identification system is provided herein. The system includes an imaging device for capturing images of a trailer connected to a vehicle, and a controller for analyzing the captured. The controller identifies vehicle and trailer contours, predicts a trailer type based on detection of a connection between the identified vehicle and trailer contours, and validates the prediction if the identified trailer contour exhibits motion during a vehicle turn event.

대표청구항 ▼

1. A trailer type identification system comprising: an imaging device capturing images of a trailer connected to a vehicle; anda controller analyzing the captured images to: identify vehicle and trailer contours;predict that the trailer is a fifth wheel trailer if unable to detect a connection between the identified vehicle and trailer contours;validate the prediction if the identified trailer contour exhibits motion during a vehicle turn event; andcontrol backing the trailer based on the prediction. 2. The trailer type identification system of claim 1, wherein the controller predicts that the trailer is a standard trailer if able to detect the connection between the identified vehicle and trailer contours. 3. The trailer type identification system of claim 1, wherein an identified vehicle contour defines a rear bumper of the vehicle. 4. The trailer type identification system of claim 1, wherein the connection comprises a connecting member providing a qualified connection between the vehicle and the trailer. 5. The trailer type identification system of claim 4, wherein the connecting member is defined by a trailer tongue and a drawbar coupled thereto. 6. The trailer type identification system of claim 4, wherein the controller considers at least one of size and shape in detecting the connecting member. 7. The trailer type identification system of claim 1, wherein the controller saves one or more captured images showing an identified trailer contour in its last known position, and wherein the controller attempts to match the one or more saved captured images to subsequently captured images in order to ascertain the identity of the trailer. 8. A trailer type identification system comprising: an imaging device capturing images of a trailer connected to a vehicle; anda controller analyzing the captured images to: identify vehicle and trailer contours;predict a trailer type based on detection of a connection between the identified vehicle and trailer contours;validate the prediction if the identified trailer contour exhibits motion during a vehicle turn event; andcontrolling backing the trailer based on the trailer type. 9. The trailer type identification system of claim 8, wherein the controller predicts that the trailer is a fifth wheel trailer if unable to detect the connection between the identified vehicle and trailer contours. 10. The trailer type identification system of claim 8, wherein the controller predicts that the trailer is a standard trailer if able to detect the connection between the identified vehicle and trailer contours. 11. The trailer type identification system of claim 8, wherein the connection comprises a connecting member providing a qualified connection between the vehicle and the trailer. 12. The trailer type identification system of claim 11, wherein the connecting member is defined by a trailer tongue and a drawbar coupled thereto. 13. The trailer type identification system of claim 11, wherein the controller considers at least one of size and shape in detecting the connecting member. 14. The trailer type identification system of claim 8, wherein the controller saves one or more captured images showing an identified trailer contour in its last known position, and wherein the controller attempts to match the one or more saved captured images to subsequently captured images in order to ascertain the identity of the trailer. 15. A trailer type identification system comprising: an imaging device capturing images of a trailer connected to a vehicle; anda controller analyzing the captured images to: detect vehicle and trailer contours;predict a trailer type based on detection of a connection between the identified vehicle and trailer contours;validate the prediction if the detected trailer contour exhibits an expected motion during a vehicle turn event; andcontrol backing the trailer based on the trailer type. 16. The trailer type identification system of claim 15, wherein the controller predicts that the trailer is a fifth wheel trailer if unable to detect the connection between the identified vehicle and trailer contours. 17. The trailer type identification system of claim 15, wherein the controller predicts that the trailer is a standard trailer if able to detect the connection between the identified vehicle and trailer contours. 18. The trailer type identification system of claim 15, wherein the expected motion is based on input related to a turn direction of the vehicle. 19. The trailer type identification system of claim 18, wherein if the input indicates a turn in a leftward direction, the expected motion occurs in a clockwise direction. 20. The trailer type identification system of claim 18, wherein if the input indicates a turn in a rightward direction, the expected motion occurs in a counterclockwise direction.
