Patent Primary Examiner
A motor vehicle includes apparatus for towing a trailer with a retractable drop leg. A backup camera captures a detection image with a field of view including the trailer. A vehicle controller detects an initiation of driving with the trailer being connected. A pattern memory prestores at least one image pattern indicative of an extended position or a retracted position of the drop leg. An image scanner receives the detection image when the initiation of driving is detected, wherein the image scanner compares the detection image and the at least one image pattern to detect whether the drop leg is in the extended position. A notification device responsive to the image scanner alerts a driver if the extended position is detected.
