Abstract

The invention pertains to methods and systems for assisting drivers, automated driver systems, and other vehicle operators with detection, avoidance, and mitigation of the hazards posed by aberrations in roadways. The invention provides complete or partial relief to vehicles traveling on roadways in a variety of conditions.

Claims

1. A method comprising:

communicating to a vehicle, in response to sensor data aggregated from a plurality of other vehicles, a probable geo-location of a road aberration and a recommended vehicle action for traversing the road aberration, wherein the communicating causes an action selected from;

a change in the vehicle operation;

a physical change to the vehicle; and

a change in a driver alert system within the vehicle.

2. The method of claim 1, wherein the probable geo-location for the road aberration is determined from the sensor data aggregated from the plurality of other vehicles, and the recommended vehicle action is determined from aggregated sensor data.

3. The method of claim 1, wherein the probable geo-location for the road aberration is determined from the sensor data aggregated from the plurality of other vehicles, and the recommended vehicle action is determined from aggregated sensor data, and wherein the aggregated sensor data comprises geo-location and vehicle action data from a plurality of vehicles, each vehicle having encountered the road aberration.

4. A method comprising:

receiving from a plurality of vehicles, by a computer system via a network, sensor data pertaining to a road segment, wherein the road segment comprises a road aberration and wherein the sensor data from each of the plurality of vehicles corresponds to an encounter of the vehicle with the road aberration, and wherein the sensor data comprises geo-location data and vehicle action data;

producing aggregated sensor data by processing the sensor data in the computer system;

determining a probable geo-location for the road aberration by the computer system from the aggregated sensor data;

determining a recommended vehicle action for the road aberration by the computer system from the aggregated sensor data; and

communicating to a vehicle positioned in the road segment or adjacent to the road segment the determined probable geo-location of the road aberration and the determined recommended vehicle action.

5. The method of claim 4, wherein the method further comprises adding the determined probable geo-location for the road aberration and the determined recommended vehicle action to a digital map comprising the road segment.

6. The method of claim 4, wherein the communicating causes an action selected from:

a change in the vehicle operation;

a physical change to the vehicle; and

a change in a driver alert system within the vehicle.

7. The method of claim 4, wherein the communicating causes a change in the vehicle operation, and wherein the vehicle takes an action consistent with the determined recommended vehicle action.

8. The method of claim 4, wherein the communicating causes a mechanical reconfiguration of a physical component of the vehicle, and wherein the physical component is a suspension system of the vehicle.

9. The method of claim 4, wherein the sensor data for each of the plurality of vehicles is obtained from a mobile device disposed within the vehicle.

10. The method of claim 4, wherein the method further comprises adding the determined probable geo-location for the road aberration and the determined recommended vehicle action to a digital map comprising the road segment, and wherein the communicating causes an action selected from:

a change in the vehicle operation;

a physical change to the vehicle; and

a change in a driver alert system within the vehicle.

11. The method of claim 4, wherein the method further comprises characterizing and labeling the road aberration according to the sensor data and wherein the communicating causes an action selected from:

a change in the vehicle operation;

a physical change to the vehicle; and

a change in a driver alert system within the vehicle.

12. The method of claim 4, wherein the sensor data further comprises vehicle type information and wherein the communicating causes an action selected from:

a change in the vehicle operation;

a physical change to the vehicle; and

a change in a driver alert system within the vehicle.

13. The method of claim 4, wherein the sensor data further comprises vehicle type information, and the determined recommended vehicle action is matched to a vehicle type of the vehicle positioned in the road.

14. The method of claim 4, wherein the sensor data further comprises vehicle type information, and wherein the method further comprises adding to a digital map the determined probable geo-location for the road aberration, and the determined recommended vehicle action indexed by vehicle type.

15. A computer system, comprising:

a processor; and

a memory coupled to the processor, the memory configured to store program instructions executable by the processor to cause the computer system to implement;

receiving from a plurality of vehicles, by the computer system via a network, sensor data pertaining to a road segment, wherein the road segment comprises a road aberration and wherein the sensor data from each of the plurality of vehicles corresponds to an encounter of the vehicle with the road aberration, and wherein the sensor data comprises geo-location data and vehicle action data;

producing aggregated sensor data by processing the sensor data in the computer system;

determining a probable geo-location for the road aberration by the computer system from the aggregated sensor data;

determining a recommended vehicle action for the road aberration by the computer system from the aggregated sensor data; and

communicating to a vehicle positioned in the road segment or adjacent to the road segment the determined probable geo-location of the road aberration and the determined recommended vehicle action.

16. The system of claim 15, wherein the system further comprises a digital map, and wherein the computer system is configured to add the determined probable geo-location for the road aberration and the determined recommended vehicle action to the digital map, and wherein the communication is configured to cause an action selected from:

a change in the vehicle operation;

a physical change to the vehicle; and

a change in a driver alert system within the vehicle.

17. The system of claim 15, wherein the system is further configured to characterize and label the road aberration according to the sensor data and wherein the communication is configured to cause an action selected from:

a change in the vehicle operation;

a physical change to the vehicle; and

a change in a driver alert system within the vehicle.

18. A method comprising:

communicating to a vehicle positioned in a road segment a probable geo-location of a road aberration and a recommended vehicle action, the road aberration being located in the road segment or adjacent to the road segment, the probable geo-location of the road aberration and the recommended vehicle action having been calculated from sensor data from a plurality of vehicles.

19. The method of claim 18, further comprising determining a feature selected from vehicle type, vehicle age, vehicle performance capability, driver age, driver skill, and environmental situation, and

further comprising matching the recommended vehicle action with the determined feature.

20. The method of claim 18, wherein each of the plurality of vehicles is characterized by vehicle type, and wherein the method comprises forming a digital map of road aberrations and corresponding recommended vehicle actions from sensor data received from the plurality of vehicles, and wherein the communicating is initiated using a proximity function determining a distance of the vehicle from the road aberration.
