Abstract

A trailer sideswipe avoidance system for a vehicle towing a trailer is disclosed. The trailer sideswipe avoidance system includes a sensor system configured to detect objects in an operating environment of the vehicle. The trailer sideswipe avoidance system may include a controller that processes information received from the sensor system to determine whether the object detected in the operating environment of the vehicle is in the travel path of the towed trailer. A visual display displays a trailer collision alert zone and a trailer collision avoidance zone. The position of the trailer collision avoidance zone on the visual display relative to the position of the trailer collision alert zone on the visual display directionally corresponds with a collision avoidance steering angle of the vehicle relative to a current steering angle of the vehicle when the controller determines that the object is in the travel path of the towed trailer.

First claim

What is claimed is:

1. A trailer sideswipe avoidance system for a vehicle towing a trailer, comprising:
a sensor system configured to detect one or more objects in an operating environment of the vehicle;
a controller that processes information received from the sensor system to determine whether an object detected in the operating environment of the vehicle is in a travel path of the towed trailer as the vehicle turns; and
a visual display that displays a trailer collision alert zone and a trailer collision avoidance zone at respective positions on the visual display, wherein the position of the trailer collision avoidance zone on the visual display relative to the position of the trailer collision alert zone on the visual display directionally corresponds with a collision avoidance steering angle of the vehicle relative to a current steering angle of the vehicle when the controller determines that the object is in the travel path of the towed trailer, and wherein the position of the trailer collision avoidance zone on the visual display relative to the position of the trailer collision alert zone on the visual display directionally corresponds with the current steering angle of the vehicle relative to a collision inducing steering angle of the vehicle when the controller determines that the object is outside of the travel path of the towed trailer.

2. The trailer sideswipe avoidance system of claim 1 , wherein the trailer collision alert zone is a different color than the trailer collision avoidance zone.

3. The trailer sideswipe avoidance system of claim 1 , wherein the trailer collision avoidance zone includes a first subzone and a second subzone, wherein the second subzone is positioned further than the first subzone from the trailer collision alert zone, and wherein each of the first subzone, the second subzone, and the trailer collision alert zone are different colors.

4. The trailer sideswipe avoidance system of claim 1 , wherein the trailer collision avoidance zone and the trailer collision alert zone generally form an arc on the visual display.

5. The trailer sideswipe avoidance system of claim 4 , wherein the controller is further configured to prompt the visual display to display a steering indicator that represents the current steering angle of the vehicle, wherein the steering indicator corresponds with the trailer collision alert zone when the controller determines that the object is in the travel path of the towed trailer.

6. The trailer sideswipe avoidance system of claim 5 , wherein the steering indicator corresponds with the trailer collision avoidance zone when the controller determines that the object is outside of the travel path of the towed trailer.

7. A method of operating a trailer sideswipe avoidance system for a vehicle towing a trailer, comprising the steps of:
detecting an object in an operating environment of the vehicle;
determining the object is in a travel path of the towed trailer;
displaying a trailer collision alert zone and a trailer collision avoidance zone at respective positions on a visual display, wherein the position of the trailer collision avoidance zone on the visual display relative to the position of the trailer collision alert zone on the visual display directionally corresponds with a collision avoidance steering angle of the vehicle relative to a current steering angle of the vehicle;
displaying a steering indicator on the visual display, wherein the steering indicator represents the current steering angle of the vehicle;
steering the vehicle to achieve the collision avoidance steering angle; and
modifying the position of the steering indicator on the visual display from a first position, wherein the steering indicator corresponds with the trailer collision alert zone, to a second position, wherein the steering indicator corresponds with the trailer collision avoidance zone.

8. The method of claim 7 , further comprising the step of:
modifying the position of the trailer collision alert zone on the visual display based on information from a sensor system of the vehicle.

9. The method of claim 7 , wherein the trailer collision alert zone is a different color than the trailer collision avoidance zone.

10. The method of claim 7 , wherein the trailer collision avoidance zone includes a first subzone and a second subzone, wherein the second subzone is positioned further than the first subzone from the trailer collision alert zone, and wherein each of the first subzone, the second subzone, and the trailer collision alert zone are different colors.

11. The trailer sideswipe avoidance system of claim 7 , wherein the trailer collision avoidance zone and the trailer collision alert zone generally form an arc on the visual display.
