Abstract

A method and system for using data associated with a first vehicle and a given road segment defined for a road network and using data associated with a second vehicle and the given road segment to determine a multi-vehicle probability value that indicates a probability that the first vehicle and the second vehicle will arrive at a common position of the given road segment simultaneously. The multi-vehicle probability value can be compared to a threshold probability value to determine whether the first vehicle and/or the second vehicle should take a responsive measure to avoid those vehicles arriving at the common position of the given road segment simultaneously. The data associated the first vehicle and the data associated with the second vehicle can each include a respective electronic horizon for that vehicle, and time parameters and probability values associated with those vehicles being on the given road segment.

Claims

1. A method comprising:

generating a first set of vehicle data at a first vehicle, the first set of vehicle data describing a first electronic horizon for the first vehicle;

sending the first set of vehicle data to a wireless access point;

receiving, from the wireless access point, data indicative of an intersection of the first electronic horizon for the first vehicle and a second electronic horizon for a second vehicle; and

providing, using a vehicle implemented processor, data indicative of at least one path of a road network on which the first vehicle can travel based on the intersection of the first electronic horizon and the second electronic horizon.

2. The method of claim 1, wherein the wireless access point is not near the road network associated with the first vehicle.

3. The method of claim 1, wherein the wireless access point is greater than five meters from the road network.

4. The method of claim 1, further comprising:

receiving a probability associated with the intersection of the first electronic horizon for the first vehicle and the second electronic horizon for the second vehicle.

5. The method of claim 1, wherein the data indicative of the intersection of the first electronic horizon for the first vehicle and the second electronic horizon for the second vehicle includes time parameters associated with a plurality of distances.

6. The method of claim 5, wherein the time parameters include expected arrival times for the plurality of distances.

7. The method of claim 1, further comprising:

providing, using the vehicle implemented processor, an alert in response to the intersection of the first electronic horizon and the second electronic horizon.

8. The method of claim 7, further comprising:

receiving an input from a user to turn off the alert.

9. The method of claim 1, wherein a speed or direction of the first vehicle or second vehicle is changed in response to the intersection of the first electronic horizon and the second electronic horizon.

10. The method of claim 1, further comprising:

receiving a selection of a route to a destination in response to the intersection of the first electronic horizon and the second electronic horizon.

11. An apparatus comprising:

a position determination device configured to generate a first set of vehicle data at a first vehicle, the first set of vehicle data describing a first electronic horizon for the first vehicle;

a communications interface configured to send the first set of vehicle data to a wireless access point and receive, from the wireless access point, data indicative of an intersection of the first electronic horizon for the first vehicle and a second electronic horizon for a second vehicle; and

a vehicle implemented processor configured to provide data indicative of at least one path on which the first vehicle can travel based on the intersection of the first electronic horizon and the second electronic horizon.

12. The apparatus of claim 11, wherein the communication interface transmits and receives radio frequency communications with the wireless access point.

13. The apparatus of claim 11, wherein the data indicative of an intersection of the first electronic horizon for the first vehicle and the second electronic horizon for the second vehicle includes time parameters associated with a plurality of distances.

14. The apparatus of claim 13, wherein the time parameters include expected arrival times for the plurality of distances.

15. The apparatus of claim 13, wherein the vehicle implemented processor is configured to provide an alert in response to the intersection of the first electronic horizon and the second electronic horizon.

16. The apparatus of claim 15, further comprising:

a user interface including a switch to generate a signal from a user input to turn off the alert or a selection of a route to a destination in response to the alert.

17. A method comprising:

receiving, at a wireless access point, a first set of vehicle data from a first vehicle, the first set of vehicle data describing a first electronic horizon for the first vehicle; and

calculating, by the wireless access point, data indicative of an intersection of the first electronic horizon for the first vehicle and a second electronic horizon for a second vehicle,

wherein a vehicle implemented processor is operable to provide data indicative of at least one path of a road network on which the first vehicle can travel based on the intersection of the first electronic horizon and the second electronic horizon.

18. The method of claim 17, wherein the wireless access point is not near the road network associated with the first vehicle.

19. The method of claim 17, wherein the wireless access point is greater than five meters from the road network.

20. The method of claim 17, further comprising:

calculating a probability of the intersection of the first electronic horizon for the first vehicle and the second electronic horizon for the second vehicle.
