Apparatus, system, and method for back up control of a towed vehicle

A signal bearing medium tangibly embodying a program of machine-readable instructions executable by a digital processing apparatus to perform an operation to control back up of a towed-vehicle, the operation comprising:

• interpreting a back up signal indicating that a towing-vehicle is backing up;
• interpreting a misalignment signal indicating that a towed-vehicle is misaligned;
• and
• producing a turn mode signal indicating a direction to turn the steering wheel of the towed-vehicle in response to the back up signal and the misalignment signal.

A system for back up control of a towed-vehicle, the system comprising:

• a back up detector producing a back up signal indicating that a towing-vehicle is backing up;
• at least one misalignment sensor producing a misalignment signal indicating that a towed-vehicle is misaligned;
• a controller interpreting the back up signal and the misalignment signal, the controller producing a turn mode signal in response to the back up signal and the misalignment signal;
• and
• a misalignment responder coupled to the steering wheel of a towed-vehicle, the misalignment responder turning the steering wheel in response to the turn mode signal.
