Relative positioning for vehicles using GPS enhanced with bluetooth range finding

The present invention relates generally to vehicle communication systems, and more particularly to a method and apparatus for communicating between multiple vehicles in close proximity to each other. 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.
