A vehicle 1 towing a trailer 4 is fitted with three video cameras 5, 6, 7 fitted to the rear of the vehicle and on each door mirror. A view from any camera can be presented to the driver on a display 11. A predicted trailer path, calculated in a computing unit 10, is also presented to the driver on the display 11 as guide lines overlaid on the camera view. The computing unit 10 is also configured to calculate a hitch angle by tracking the position of a trailer-mounted marker in the camera view.
1. A system for determining a hitch angle of a trailer attached to a vehicle, comprising: a camera operable to capture images rearward of the vehicle;an image processor processing the captured images and locating a position of a marker on the trailer; anda computer determining the hitch angle betwee
1. A system for determining a hitch angle of a trailer attached to a vehicle, comprising: a camera operable to capture images rearward of the vehicle;an image processor processing the captured images and locating a position of a marker on the trailer; anda computer determining the hitch angle between the vehicle and the trailer based on the position of the located marker. 2. The system of claim 1, wherein the camera is located on the vehicle. 3. The system of claim 1, wherein the marker comprises at least one of a mark, a sticker attached to the trailer and an edge of the trailer. 4. The system of claim 1 further comprising a display for displaying a trailer view visible to a driver of the vehicle. 5. The system of claim 1, further comprising a steering angle sensor for sensing a vehicle steering angle, wherein the computer further calculates a predicted path of a trailer from the hitch angle and the vehicle steering angle. 6. The system of claim 1 further comprising the step of displaying the marker on a display for a driver confirmation that the selected marker is rigidly connected to the trailer. 7. The system of claim 1, wherein the computer compares the hitch angle to a stored value and, if the hitch angle is within a predetermined range of the stored value, wherein the trailer is likely to jack-knife, generating a warning signal to the driver indicative of an imminent jack-knife event. 8. A method of determining a hitch angle of a trailer towed by a vehicle, comprising: obtaining an image of a trailer towed by the vehicle with a camera;tracking a position of a marker associated with the trailer in the image with an image processor; anddetermining with a computer the hitch angle between the vehicle and trailer based on the position of the marker. 9. The method of claim 8, wherein the camera is located on the vehicle. 10. The method of claim 8 further comprising the steps of: measuring a steering angle of the vehicle; andcalculating with the computing unit a predicted path of the trailer from the hitch angle and steering angle. 11. The method of claim 10 further comprising the step of displaying the predicted trailer path on a display as an overlay track on the image. 12. The method of claim 8, wherein the marker comprises at least one of a mark, a sticker attached to the trailer and an edge of the trailer. 13. The method of claim 8 further comprising the step of displaying a trailer view visible to a driver of the vehicle. 14. The method of claim 8 further comprising the step of displaying the marker on a display for a driver confirmation that the selected marker is rigidly connected to the trailer. 15. The method of claim 8 further comprising the steps of comparing the hitch angle to a stored value and, if the hitch angle is within a predetermined range of the stored value, wherein the trailer is likely to jack-knife, generating a warning signal to the driver indicative of an imminent jack-knife event. 16. A method of predicting a path of a trailer attached to a vehicle, comprising: measuring a vehicle steering angle;obtaining an image of the trailer with a video camera;tracking a position of a marker associated with the trailer in the image using an image processor;determining a hitch angle between the vehicle and trailer based on the position of the marker using a computer; andcalculating a predicted path of the trailer from the hitch angle and vehicle steering angle using the computer. 17. The method of claim 16, wherein the camera is located on the vehicle. 18. The method of claim 16 further comprising the step of displaying the predicted trailer path on a display. 19. The method of claim 18 further comprising the step of displaying the predicted trailer path on a display as an overlay track on the image. 20. The method of claim 16, wherein the marker comprises at least one of a mark, a sticker attached to the trailer and an edge of the trailer.
