Abstract: A wireless vehicle-trailer interface system for communication between a vehicle and a trailer is provided. The vehicle may include a vehicle hitch, a vehicle control system, a vehicle radio frequency system, and a processor, the processor configured to generate a unique data packet for each vehicle radio frequency system, determine, for each received response packet, a distance between a corresponding receiving vehicle radio frequency system and a corresponding transmitting trailer radio frequency systems, determine a relative physical position of each vehicle radio frequency system and trailer radio frequency system, determine dimensions of the trailer, determine a physical position of a vehicle hitch and a trailer coupled, and generate instructions for the vehicle control system to cause the vehicle to move to align the vehicle hitch with a trailer coupler.
