## Abstract

A system according to the present disclosure includes a trailer distance module, a trailer contact module, a trailer distance module, and at least one of a driver warning module, a brake control module, and a steering control module. The trailer distance module determines a distance from a cab of a truck to a fifth wheel trailer attached to the truck based on an input from a sensor. The trailer contact module identifies potential contact between the trailer and the truck cab based on the cab-to-trailer distance. The driver warning module warns a driver of the potential contact. The brake control module applies a brake of at least one of the truck and the trailer when potential contact is identified. The steering control module increases an amount of driver effort required to steer the truck in at least one direction when potential contact is identified.

### Claim 4 (depends on 3)

The system of claim 3 wherein:
the trailer angle module determine a current angle between the centerline of the fifth wheel trailer and the centerline of the truck; and
the trailer contact module identifies potential contact between the fifth wheel trailer and the truck cab based on a comparison of the current angle and the contact angle.

### Claim 5 (depends on 1)

the sensor is a camera mounted to the truck cab and operable to generate an image of the trailer; and
the trailer distance module determines the cab-to-trailer distance based on the image.

### Claim 6 (depends on 5)

The system of claim 5 wherein:
the camera is operable to generate a first image of the fifth wheel trailer before the truck and the fifth wheel trailer travel a first distance;
the camera is operable to generate a second image of the fifth wheel trailer after the truck and the fifth wheel trailer travel the first distance; and
the trailer distance module determines the cab-to-trailer distance based on the first and second images of the trailer and the first distance using vision-based ranging.
