ABSTRACT:
A system for electronically locating particular vehicles from within a large plurality of vehicles parked on a holding lot of an assembly plant. A control system transmits a signal encoded with a particular Vehicle Identification Number (VIN) to a plurality of signal repeaters disposed on lamp posts or other fixed items throughout the holding lot, where the lamp posts or other like items are disposed in a grid pattern or network over the holding lot. The signal repeaters transmit VIN-encoded low power radio frequency signals covering the entire holding lot. Each vehicle includes a Single Body Engine Controller (SBEC) which includes the VIN of the vehicle and a Body Control Module (BCM) in communication with its associated SBEC which is capable of activating the Vehicle Theft Alarm (VTA) of the vehicle, to thereby activate the horn and/or lights of the vehicle. The VTA includes an RF receiver associated therewith which receives the RF signal from the repeaters. The BCM checks to determine if the VIN encoded in its SBEC matches the VIN encoded in the received RF signal. If so, the BCM activates the lights and/or horn of the vehicle. Alternatively, the BCM or the VTA includes a radio frequency transceiver which transmits a location identifying signal back to one or more repeaters disposed closely adjacent the vehicle. The location identifying signal is displayed on a display system to enable the location of the vehicle to be relatively precisely determined on the holding lot.
