Abstract

Systems and methods for managing a formation of vehicles include at least one of the vehicles having a crossbar switch and a unidirectional antenna coupled to the crossbar switch. The vehicle is configured to form several networks, each including the vehicle and each other vehicle of the formation, using the crossbar switch and the antenna.

Claims

1. A system comprising:

a first vehicle including a crossbar switch and a unidirectional antenna coupled to the crossbar switch, the first vehicle being configured to form a plurality of networks each including the first vehicle and a second vehicle traveling in a formation with the first vehicle using the crossbar switch and the antenna.

2. The system of claim 1, wherein each of the networks is configured for supporting a different service for the formation.

3. The system of claim 1, wherein a first one of the networks is configured to support collective decision making for resolving a travel dilemma of the formation, and a second one of the networks is configured to support maintaining the formation.

4. The system of claim 3, wherein the first network is configured to support collective decision making for passing the formation through an upcoming traffic signal.

5. The system of claim 3, wherein the second network is configured to support maintaining a predefined gap between the first vehicle and the second vehicle.

6. The system of claim 1, further comprising a database including quality of service data for each of the networks stored on the first vehicle, wherein the first vehicle is configured to form each network based on the quality of service data for the network included in the database.

7. The system of claim 6, wherein the second vehicle comprises a plurality of second vehicles, the database includes a network topology for the first vehicle and the second vehicles for each network, and the first vehicle is configured to form each network based on the network topology for the network included in the database.

8. The system of claim 1, wherein responsive to receiving timing data from an upcoming traffic signal, the first vehicle is configured to

transmit a first ranked list of potential actions for the formation generated based on the timing data to the second vehicle over one of the networks;

and

responsive to receiving a second ranked list of potential actions for the formation from the second vehicle over the one network

identify a preferred action based on the first ranked list and the second ranked list, and

implement the preferred action.

9. The system of claim 8, wherein the potential actions for the formation include stopping the formation before an intersection of the upcoming traffic signal, passing the formation through the intersection, and splitting the formation such that the first vehicle passes through the intersection and the second vehicle stops before the intersection.

10. The system of claim 1, wherein responsive to a third vehicle entering the formation between the first and second vehicles, the first vehicle is configured to automatically reconfigure the networks to each include the first, second, and third vehicles.

11. A system comprising:

a plurality of vehicles traveling in a formation, each vehicle including a crossbar switch and a plurality of unidirectional antennas coupled to the crossbar switch and being configured to form a plurality of networks each including the vehicles using the crossbar switch and at least one of the antennas of the vehicle.

12. The system of claim 11, wherein a first one of the networks is configured to support collective decision making by the formation, and a second one of the networks is configured to support maintaining the formation.

13. The system of claim 11, wherein each vehicle includes a database having quality of service data for each network, and each vehicle is configured to form each network according to the quality of service data for the network in the database of the vehicle.

14. The system of claim 13, wherein the database of each vehicle further includes a network topology for the vehicles of the formation for each network, and each vehicle is configured to form each network based on the network topology for the network stored in the vehicle.

15. The system of claim 11, wherein responsive to receiving timing data from an upcoming traffic signal, each vehicle is configured to:

transmit a first ranked list of potential actions for the formation generated based on the timing data to each other vehicle of the formation over one of the networks; and

responsive to receiving a second ranked list of potential actions from each other vehicle of the formation over the one network

identify a preferred action based on the first ranked list and the second ranked list from each other vehicle of the formation, and

implement the preferred action.

16. A method comprising:

forming, by a first vehicle, a plurality of networks each including the first vehicle and a second vehicle traveling in a formation with the first vehicle via a crossbar switch of the first vehicle and a unidirectional antenna of the first vehicle facing the second vehicle.

17. The method of claim 16 further comprising:

supporting a collective decision making service for the formation via a first one of the networks; and

supporting a formation maintenance service via a second one of the networks.

18. The method of claim 16, wherein the second vehicle comprises a plurality of second vehicles, and further comprising forming each network based on a topology for the first vehicle and the second vehicles that is stored for the network in the first vehicle.

19. The method of claim 16 further comprising, by the first vehicle, responsive to receiving timing data from an upcoming traffic signal:

transmitting a first ranked list of potential actions for the formation generated based on the timing data to the second vehicle over one of the networks;

identifying a preferred action based on the first ranked list and a second ranked list of potential actions received from the second vehicle; and

implementing the preferred action.

20. The method of claim 16, further comprising, responsive to a third vehicle entering the formation between the first and second vehicles, reconfiguring the networks to each include the first, second, and third vehicles.
