Abstract: A CMS for a vehicle includes a camera that is mounted to a tractor and records images that depict a trailer having a wheelbase. An electronic display displays the images. A CMS controller is operatively connected to the camera and electronic display. The CMS controller performs image processing on the images to extract at least the wheelbase. The CMS controller determines whether a trailer angle of the trailer exceeds a jackknife warning threshold based on a depiction of the trailer in the images. A distance to a jackknife event is depicted on the display if the jackknife warning threshold is exceeded.
