Abstract

A system and method for routing based on a predicted connectivity quality is disclosed. The method includes receiving, by a controller, map information corresponding to a geographical area. The method also includes receiving, by the controller, wireless connectivity information corresponding to the geographical area. The method also includes generating output data of at least one route between a starting location and a destination location within the geographical area. The generating is based on the wireless connectivity information.

First claim

What is claimed is:

1. A method, the method comprising:
receiving, by a controller, map information corresponding to a geographical area;
for locations within the geographical area, identifying nodes by infrastructure that provide wireless communication to those locations based upon crowd-sourced information;
determining which of the locations have wireless connectivity based on the node infrastructure;
determining quality of wireless connectivity information of the locations determined to have wireless connectivity, based on quality-of-service measurements including transmission latency from crowd-sourced connectivity-quality statistics;
receiving, by the controller, the quality of wireless connectivity information; and
generating output data of at least one route between a starting location and a destination location within the geographical area, wherein the generating is based on the quality of wireless connectivity information.

2. The method of claim 1 , wherein the generating is based on determined quality of wireless connectivity information for a vehicle that travels along the at least one route.

3. The method of claim 1 , wherein the generating is based on at least one of a determined travel time, a determined travel distance, and a determined average travel speed for a vehicle that travels along the at least one route.

4. The method of claim 2 , wherein the vehicle corresponds to a connected-automated vehicle that is configured to receive data for eco-driving via wireless communication.

5. The method of claim 1 , wherein the wireless connectivity information comprises measurements of vehicle-to-infrastructure connectivity and measurements of vehicle-to-vehicle connectivity.

6. The method of claim 1 , wherein the quality-of-service measurements comprise measurements corresponding to at least one of an error rate, a transfer rate, and a signal jitter.

7. The method of claim 1 , wherein the starting location corresponds to a current vehicle location.

8. The method of claim 1 , wherein the generated at least one route corresponds to a route with an optimized determined cost, wherein the cost is based on a determined travel time and a determined amount of fuel used.

9. A system within a vehicle, comprising:
an electronic controller configured to:
receive map information corresponding to a geographical area;
for locations within the geographical area, identify nodes by infrastructure that provide wireless communication to those locations based upon crowd-sourced information;
determine which of the locations have wireless connectivity based on the node infrastructure;
determine quality of wireless connectivity information of the locations determined to have wireless connectivity, based on quality-of-service measurements including transmission latency from crowd-sourced connectivity-quality statistics;
receive the quality of wireless connectivity information; and
generate output data of at least one route between a starting location and a destination location within the geographical area, wherein the generating is based on the quality of wireless connectivity information.

10. The system of claim 9 , wherein the generating is based on determined quality of wireless connectivity information for a vehicle that travels along the at least one route.

11. The system of claim 9 , wherein the generating is based on at least one of a determined travel time, a determined travel distance, and a determined average travel speed for a vehicle that travels along the at least one route.

12. The system of claim 10 , wherein the vehicle corresponds to a connected-automated vehicle that is configured to receive data for eco-driving via wireless communication.

13. The system of claim 9 , wherein the wireless connectivity information comprises measurements of vehicle-to-infrastructure connectivity and measurements of vehicle-to-vehicle connectivity.

14. The system of claim 9 , wherein the quality-of-service measurements comprise measurements corresponding to at least one of an error rate, a transfer rate, and a signal jitter.

15. The system of claim 9 , wherein the starting location corresponds to a current vehicle location.

16. The system of claim 9 , wherein the generated at least one route corresponds to a route with an optimized determined cost, wherein the cost is based on a determined travel time and a determined amount of fuel used.
