Abstract

A system and method for wirelessly exchanging information concerning the location of E85 gas stations between E85 vehicles. The method includes transmitting messages from an E85 gas station that identifies the location of the E85 gas station, the time of the transmission and the price of the E85 gas, and receiving the messages by E85 vehicles that pass within a certain distance of the E85 gas station. The method also includes identifying that two E85 vehicles pass close to each other, where the vehicles periodically broadcast an E85 beacon identifying them as E85 vehicles. When two E85 vehicles are identified, the vehicles exchange information concerning a list of the E85 gas stations that they have stored from messages received from E85 gas stations and/or other E85 vehicles. The two vehicles update their lists to include those E85 gas stations that one vehicle may have that the other does not.

Claims

1. A method for exchanging information concerning E85 gas stations between E85 vehicles, said method comprising:

broadcasting messages from an E85 gas station that include the location of the E85 gas station, the time of the broadcast and the price of the E85 gas;

receiving and storing the messages on E85 vehicles that pass within a certain distance of the E85 gas station;

identifying two vehicles as E85 vehicles that pass close to each other; and

exchanging information between the two E85 vehicles concerning the E85 gas stations stored on the two vehicles so that a first vehicle receives and stores information about E85 gas stations from a second vehicle and the second vehicle receives and stores information about E85 gas stations from the first vehicle.

2. The method according to claim 1 wherein exchanging information between the two vehicles concerning the E85 gas stations includes exchanging an index list of the E85 gas stations stored on the first and second vehicles that includes a station ID number and a time stamp of when the original information about the E85 gas station was generated.

3. The method according to claim 2 wherein exchanging information between the two E85 vehicles concerning the E85 gas stations includes identifying which E85 gas stations in the index list received by the first or the second vehicle are not currently stored by that vehicle, and then requesting that the other first or second vehicle send complete information about the E85 gas station for the stations that the first or second vehicle does not have.

4. The method according to claim 3 wherein the full information includes gas station ID number, gas station location, time stamp, and gas price.

5. The method according to claim 2 wherein exchanging information between the two E85 vehicles concerning the E85 gas stations includes exchanging complete information about the E85 gas stations for those E85 gas stations that the first or second vehicle has stored, but the other first or second vehicle has a more recent time stamp for that E85 gas station.

6. The method according to claim 1 wherein storing the messages on the E85 vehicle includes storing information concerning the E85 gas stations ID number, its location, a time stamp when the information was generated and the current price of the E85 gas of that E85 gas station.

7. The method according to claim 6 wherein storing the messages on the E85 vehicles also include storing a coupon that provides value for purchasing gas at the E85 gas station.

8. The method according to claim 1 wherein broadcasting messages from an E85 gas station includes using a short range communication transmitter.

9. The method according to claim 1 wherein the certain distance is less than 5 kilometers.

10. The method according to claim 1 wherein identifying two vehicles as E85 vehicles includes periodically transmitting a beacon from a vehicle identifying the vehicle as an E85 vehicle and receiving the beacon by another E85 vehicle.

11. A method for exchanging information concerning E85 gas stations between E85 vehicles, said method comprising:

broadcasting messages from an E85 gas station that include the location of the E85 gas station, the time of the broadcast and the price of the E85 gas;

receiving and storing the messages on E85 vehicles that pass within a certain distance of the E85 gas station;

identifying two vehicles as E85 vehicles that pass close to each other; and

exchanging information between the two E85 vehicles concerning the E85 gas stations stored on the two vehicles so that one of the vehicles receives and stores information about E85 gas stations from the other vehicle and the other vehicle receives and stores information about E85 gas stations from the one vehicle, wherein exchanging information between the two vehicles includes first exchanging an index list of the E85 gas stations stored on the two E85 vehicles that only includes a station ID number and a time stamp of when the vehicle received the information about the E85 gas station, identifying E85 gas station information that each of the two vehicles do not have that are on the other vehicles index list, identifying the E85 gas station ID numbers that are common between the two vehicles, but one vehicles time stamp for that E85 gas station is more current than the other vehicles time stamp for that E85 gas station, and requesting that the vehicles transmit a complete list of information concerning the E85 gas stations that one vehicle has but the other does not have and one vehicle has a more current time stamp for where the complete information includes the E85 gas station ID number, its location, a time stamp when the information is received and the current price of the E85 gas at that time.

12. The method according to claim 11 wherein storing the messages on the E85 vehicles also include storing a coupon that provides value for purchasing gas at the E85 gas station.

13. The method according to claim 11 wherein broadcasting messages from an E85 gas station includes using a short range communication transmitter.

14. The method according to claim 11 wherein identifying two vehicles as E85 vehicles includes periodically transmitting a beacon from a vehicle identifying the vehicle as an E85 vehicle and receiving the beacon by another E85 vehicle.

15. A system for exchanging information concerning E85 gas stations between E85 vehicles, said system comprising:

means for broadcasting messages from an E85 gas station that include the location of the E85 gas station, the time of the broadcast and the price of the E85 gas;

means for receiving and storing the messages on E85 vehicles that pass within a certain distance of the E85 gas station;

means for identifying two vehicles to each other as E85 vehicles that pass close to each other; and

means for exchanging information between the two vehicles concerning the E85 gas stations stored on the two vehicles where one of the vehicles receives and stores information about E85 gas stations from the other vehicle that it does not have and the other vehicle receives and stores information about E85 gas stations from the one vehicle that it does not have.

16. The system according to claim 15 wherein the means for exchanging information between the two vehicles concerning the E85 gas stations exchanges an index list of the E85 gas stations stored on the vehicles that includes a station ID number and a time stamp of when the original information about the E85 gas station was generated.

17. The system according to claim 16 wherein the means for exchanging information between the two E85 vehicles concerning the E85 gas stations includes identifying which E85 gas stations in the index list received by the one or other vehicle are not currently stored by that vehicle, and then requesting that the one or other vehicle send complete information about the E85 gas station for the stations that the one or other vehicle does not have.

18. The system according to claim 16 wherein the means for exchanging information between the two E85 vehicles concerning the E85 gas stations exchanges complete information about the E85 gas stations for those E85 gas stations that the one or other vehicle has stored, but the one or other vehicle has a more recent time stamp for that E85 gas station.

19. The system according to claim 15 wherein the means for storing the messages on the E85 vehicle stores information concerning the E85 gas stations ID number, its location, a time stamp when the information was generated and the current price of the E85 gas.

20. The system according to claim 19 wherein the means for storing the messages on the E85 vehicles also stores a coupon that provides value for purchasing gas at the E85 gas station.
