초록 ▼

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.

대표청구항 ▼

1. A relative vehicle positioning system for a first vehicle comprising:a GPS antenna adapted to receive satellite signals generated in response to relative vehicle positioning and generate therefrom a GPS signal;a first Bluetooth radio coupled to the first vehicle and adapted to exchange bearing information with a second vehicle and generate therefrom a PVT signal;a second Bluetooth radio coupled to the first vehicle and adapted to synchronize the first vehicle with said second vehicle; anda GPS unit comprising a controller adapted to receive said GPS signal and said PVT signal and generate therefrom, a GPS-Bluetooth relative position signal. 2. The system of claim 1 wherein said second Bluetooth radio is adapted to transfer data to other Bluetooth radios attached to said GPS unit to support Differential GPS and interferometric methods. 3. The system of claim 1 wherein said second Bluetooth radio and a third Bluetooth radio on said second vehicle generate a mesh topology network on which said synchronization is performed. 4. The system of claim 1 wherein a time synchronization is generated between said first Bluetooth radio and a second Bluetooth radio on said second vehicle through a piconet Bluetooth configuration. 5. The system of claim 1 wherein said GPS-Bluetooth generates a platoon signal whereby a human operator or a control system receive said platoon signal and control a number of vehicles in a formation in response thereto. 6. The system of claim 1 wherein said GPS-Bluetooth is either battery powered or externally powered. 7. The system of claim 1 wherein a second GPS-Bluetooth is coupled to a stationary location. 8. The system of claim 1 wherein said GPS-Bluetooth is adapted to use communication protocols that can synchronize and be used for range measurements. 9. A relative vehicle positioning system for a first vehicle comprising:a GPS antenna adapted to receive satellite signals generated in response to a relative vehicle positioning and generate therefrom a GPS signal;a first Bluetooth radio adapted to exchange bearing information with a second vehicle and generate therefrom a PVT signal;a second Bluetooth radio coupled to the first vehicle adapted to synchronize the first vehicle with said second vehicle;a vehicle network adapted to generate a network signal; anda GPS unit comprising a controller adapted to receive said GPS signal, said PVT signal and said network signal, and generate therefrom, a GPS-Bluetooth relative position signal. 10. The system of claim 9 wherein said second Bluetooth radio is adapted to transfer data to other Bluetooth radios attached to said GPS unit to support Differential GPS and interferometric methods. 11. The system of claim 9 wherein said second Bluetooth radio and a third Bluetooth radio on said second vehicle generate a mesh topology network on which said synchronization is performed. 12. The system of claim 9 wherein said GPS-Bluetooth is either battery powered or externally powered. 13. A method of communicating between vehicles having GPS-Bluetooth devices comprising:receiving timing and vehicle data;generating a GPS signal;computing range through time of flight and velocity through Doppler shift;generating a GPS-Bluetooth relative position signal as a function of said timing and vehicle data, said GPS signal, said velocity and said range;sharing information between the Bluetooth devices; andsynchronizing the GPS-Bluetooth devices. 14. The method of claim 13 wherein sharing further comprises sharing ephemeris information. 15. The method of claim 13 wherein synchronizing further comprises synchronizing a piconet Bluetooth configuration. 16. The method of claim 13 further comprising generating a platoon signal whereby a human operator or a control system receive said platoon signal and control a number of vehicles in a formation in response thereto. 17. The method of claim 13 further comprising activating a vehicle system in response to said position signal, wherein said veh icle system comprises a pre-crash system, a warning system, a navigation system, an avoidance system or a safety system.
