Abstract
The present invention provides a system and method which allow for the rapid and reliable identification of towed trailers parked together in loading areas. According to a first preferred embodiment, an exemplary method of the present includes: monitoring hook-up criteria indicating that the first truck is maneuvering to hook-up with the first trailer; scanning for one or more transmitting devices when hook-up event criteria are met; determining which transmitting devices are sufficiently close to require an angle calculation based on RSSI levels; performing an Angle of Departure/Angle of Arrival calculation for each of the selected signals; determining which of the closest identified trailers have an Angle of Departure/Angle of Arrival which falls within a pre-set threshold; identifying a hook-up trailer based on detecting the Angle of Arrival/Angle of Departure and the compared RSSI levels; pairing the hook-up trailer ID device with a tractor ID device of the first truck; and transmitting paired ID information linking the hook-up trailer ID and the tractor ID device.
