RELATIVE POSITIONING FOR VEHICLES USING GPS ENHANCED WITH BLUETOOTH RANGE FINDING

摘要

A relative vehicle positioning system for a vehicle includes a GPS antenna adapted to receive satellite signals generated in response to relative vehicle positioning and generate therefrom a GPS signal. A Bluetooth radio is adapted to exchange bearing information with a second vehicle and generate therefrom a PVT signal. A GPS unit including a controller is adapted to receive the GPS signal and the PVT signal, the GPS unit is further adapted to generate therefrom a GPS-Bluetooth relative position signal.
