Abstract

Systems and methods for vehicle routing may be based on wireless network performance data. A vehicle route includes one or more path segments included in the route based on the wireless performance data. The vehicle route may be updated based on updated wireless performance data. Driving assistance features of a vehicle may be enabled by the wireless performance data, and different driving assistance features may be enabled or disabled on the vehicle route according to changes in wireless performance data. As the vehicle traverses the route, the driving assistance features may be enabled or disabled based on the wireless performance data for the path segment. The vehicle route may be updated to continue to enable a set of the driving assistance features.

First claim

We claim:

1. A method for vehicle routing comprising:
receiving, by a processor, a wireless network performance data for a wireless network and associated with a plurality of path segments;
determining, by the processor, a score for one or more path segments of the plurality of path segments, the score based on the wireless network performance data for the one or more path segments;
determining, by the processor, a vehicle route based on the score of the one or more path segments; and
outputting, by the processor, the vehicle route.

2. The method of claim 1 , further comprising:
receiving, by the processor, a driving assistance data requirement; and
determining, by the processor, whether the performance data meets or exceed the driving assistance data requirement,
wherein the score is determined based on whether the performance data meets or exceed the driving assistance data requirement for the one or more path segments.

3. The method of claim 2 , wherein the driving assistance data requirement is a data rate required to enable an advanced driver-assistance feature.

4. The method of claim 3 , wherein the advanced driver-assistance feature is an autonomous driving feature.

5. The method of claim 2 , wherein the wireless network performance data includes a measurement of available bandwidth.

6. The method of claim 5 , wherein, when a plurality of wireless networks are available for a path segment of the one or more path segments, determining the score for the path segment is determined based on a combination of the wireless network performance data of a first wireless network of the plurality of wireless networks and the wireless network performance of a second wireless network of the plurality of wireless networks.

7. The method of claim 5 , further comprising:
receiving probe data generated by one or more vehicles, the probe data including a wireless network connection status of the one or more vehicles;
determining a number of vehicles connected to the wireless network based on the probe data; and
updating, by the processor, the measurement of available bandwidth based on the number of vehicles connected to the wireless network.

8. The method of claim 7 , wherein the wireless network connection status includes a measurement of a download speed, an upload speed, or the download speed and the upload speed between the one or more vehicles and the wireless network.

9. The method of claim 1 , wherein the performance data includes a measurement of signal strength.

10. The method of claim 1 , further comprising:
receiving data describing traffic, speed, distance, weather, functional classification, elevation, curvature, grade, number of accidents, traffic lights, lane size, or a combination thereof for the one or more path segments, and
wherein the vehicle route is determined based on the data describing traffic, speed, distance, weather, functional classification, elevation, curvature, grade, number of accidents, traffic lights, lane size, or a combination thereof for the one or more path segments.

11. The method of claim 1 , wherein the wireless network performance data includes a switchover from a first wireless network type to a second wireless network type for the associated plurality of path segments.

12. The method of claim 1 , wherein the wireless network performance data is received from an operator of the wireless network.

13. The method of claim 1 , further comprising:
receiving, by the processor, a start point and an end point; and
generating, by the processor, a path from the start point to the end point, the path passing through one or more contiguous path segments of the plurality of path segments having a highest score,
wherein the vehicle route is determined based on the path.

14. A system for vehicle routing comprising:
a network resource monitor configured to receive wireless network performance data associated with a plurality of path segments;
a route composer configured to determine a score for the plurality of path segments, the score based on whether or not the wireless network performance data associated with the plurality of path segments meets or exceeds a driving assistance data requirement and determine a route based on the score of the plurality of path segments; and
a dispatcher configured to output the route.

15. The system of claim 14 , wherein the wireless network performance data includes a measurement of available bandwidth for the plurality of path segments, and
wherein the driving assistance data requirement includes a required amount of bandwidth for enabling a driving assistance feature.

16. The system of claim 15 , wherein the driving assistance data requirement includes a plurality of threshold amounts of required bandwidth, and
wherein the score for the plurality of path segments is determined based on a highest threshold amount of required bandwidth of the plurality of threshold amounts met or exceeded by the wireless network performance data associated with the path segment.

17. The system of claim 15 , wherein the network resource monitor is configured to receive probe data from one or more vehicles, the probe data including a wireless network usage of the one or more vehicles and update the measurement of available bandwidth based on the wireless network usage of the one or more vehicles.

18. The system of claim 14 , wherein the network resource monitor is configured to receive data describing traffic, speed, distance, weather, functional classification, elevation, curvature, grade, number of accidents, traffic lights, lane size, or a combination thereof for the plurality of path segments, and
wherein the vehicle route is determined based on the data describing traffic, speed, distance, weather, functional classification, elevation, curvature, grade, number of accidents, traffic lights, lane size, or a combination thereof for the plurality of path segments.

19. A non-transitory computer-readable medium including instructions that when executed are operable to:
receive a vehicle routing request including a driving assistance capability of an vehicle and a driving assistance data requirement to enable the driving assistance capability;
receive a wireless network performance data associated with a plurality of path segments;
determine a score for the plurality of path segments, the score based on whether or not the wireless network performance data associated with the path segment fulfills the driving assistance data requirement;
determine a vehicle route based on the score of the one or more path segments, the wireless network performance data for the vehicle route at least partially enabling the driving assistance capability; and
output the vehicle route.

20. The computer readable medium of claim 19 , wherein the wireless network performance data includes a measure of available bandwidth for the associated path segment, and
wherein the driving assistance data requirement includes a required amount of bandwidth to enable the driving assistance capability.
