Abstract

Systems, methods, and apparatuses are provided for determining an optimal warning distance for a vehicle. For example, the geographic location of the vehicle is received along with a reaction profile of the operator of the vehicle. Based on the geographic location, a roadway condition is determined. An optimal warning distance is then determined based on a braking distance of the vehicle and the reaction profile of the operator of the vehicle. The operator of the vehicle, or a navigation system of the vehicle itself, is alerted to the roadway condition when the vehicle is located at the optimal warning distance.

Claims

1. A method comprising:

receiving a geographic location of an autonomous vehicle;

accessing a road attribute based on the geographic location;

identifying a personalized braking distance for a passenger of the autonomous vehicle, wherein the passenger is not a driver of the vehicle;

accessing a passenger profile for the passenger in response to the passenger entering the autonomous vehicle, wherein the profile includes personalized braking distance for a comfortable rate of braking for the passenger based on a personal attribute of the passenger;

calculating an optimal warning distance based on the accessed road attribute and the personalized braking distance of the passenger; and

providing a message for the autonomous vehicle in response to the optimal warning distance.

2. The method of claim 1, wherein the message includes a command for the autonomous vehicle.

3. The method of claim 2, wherein the command is a driving command configured to operate the autonomous vehicle.

4. The method of claim 3, wherein the driving command steers the autonomous vehicle, shifts a gear of the autonomous vehicle, or adjusts a throttle of the autonomous vehicle.

5. The method of claim 3, wherein the driving command applies a brake of the autonomous vehicle.

6. The method of claim 1, wherein the message includes an alert.

7. The method of claim 1, wherein the message is an audio message or a video message relayed to the passenger of the autonomous vehicle.

8. The method of claim 1, wherein the message is provided at the optimal warning distance to a roadway condition.

9. An apparatus comprising:

at least one processor; and

at least one memory including computer program code for one or more programs;

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform;

receiving a geographic location of an autonomous vehicle;

accessing a road attribute based on the geographic location;

identifying a personalized braking distance for a passenger of the autonomous vehicle;

accessing a passenger profile for the passenger, wherein the profile includes personalized braking distance for a comfortable rate of braking for the passenger based on a personal attribute of the passenger;

calculating an optimal warning distance based on the accessed road attribute and the personalized braking distance of the passenger; and

providing a message for the autonomous vehicle in response to the optimal warning distance.

10. The apparatus of claim 9, wherein the message includes a command for the autonomous vehicle.

11. The apparatus of claim 10, wherein the command is a driving command configured to operate the autonomous vehicle.

12. The apparatus of claim 11, wherein the driving command steers the autonomous vehicle, shifts a gear of the autonomous vehicle, or adjusts a throttle of the autonomous vehicle.

13. The apparatus of claim 11, wherein the driving command applies a brake of the autonomous vehicle.

14. The apparatus of claim 9, wherein the message includes an alert.

15. The apparatus of claim 14, wherein the message is an audio message or a video message relayed to the passenger of the autonomous vehicle.

16. The apparatus of claim 15, wherein the message is provided at the optimal warning distance to a roadway condition.

17. A non-transitory computer readable medium containing program instructions for causing a computer to perform a method of:

receiving a geographic location of an autonomous vehicle;

accessing a road attribute based on the geographic location;

identifying a personalized braking distance for a passenger of the autonomous vehicle;

accessing a passenger profile for the passenger, wherein the profile includes personalized braking distance for a comfortable rate of braking for the passenger based on a personal attribute of the passenger;

calculating an optimal warning distance based on the accessed road attribute and the personalized braking distance of the passenger; and

providing a message for the autonomous vehicle in response to the optimal warning distance.

18. The non-transitory computer readable medium of claim 17, wherein the message includes a driving command that steers the autonomous vehicle, shifts a gear of the autonomous vehicle, or adjusts a throttle of the autonomous vehicle.

19. The non-transitory computer readable medium of claim 17, wherein the message includes an alert including audio or video relayed to the passenger of the autonomous vehicle at the optimal warning distance to a roadway condition.
