Abstract
Trailer guidance systems require sensors for detecting the hitch angle and the turning radius and output means for displaying the intended trailer destination. However, most vehicles do not have integral turning sensors and most trailers and/or hitches do not have integral hitch angle sensors. The present invention is a system for guiding a trailer while backing that can easily be installed or removed.
