Abstract

A method for adaptive driver guidance for navigation and location-based services. A navigation system onboard a vehicle records errors, including both system errors and user errors, where the errors can be detected by missed turns, re-routing, and similar events. The error data is transmitted to a central server, where the data is analyzed to determine patterns of errors, both for an individual driver and across many drivers. Roadway locations which frequently experience driver navigational errors have the error type integrated as a route feature, and future navigational guidance is adapted to improve driver performance. Adaptations can include increased or decreased frequency, detail, timing and location of navigational instructions. Individual driver guidance can also be adapted based on the driver'"'"'s tendency to make errors in response to specific guidance instructions. Adaptation of guidance for location-based services is also provided.

Claims

1. A method for providing adaptive guidance for driver navigation, said method comprising:

recording navigation error data for navigation errors detected by a navigation system in a vehicle;

analyzing the navigation error data to detect patterns in the navigation errors; and

providing adaptive driver navigation guidance, where adaptations in guidance are made based on the patterns in the navigation errors.

2. The method of claim 1 further comprising communicating the navigation error data to a server computer.

3. The method of claim 2 wherein analyzing the navigation error data is performed on the server computer, and the server computer communicates with a route planning system which provides the adaptive driver navigation guidance.

4. The method of claim 1 wherein analyzing the navigation error data and providing adaptive driver navigation guidance are performed on the navigation system in the vehicle.

5. The method of claim 1 wherein navigation errors include navigation system errors and driver errors, and driver errors are detected by route recalculation, driver request for more information, or departure from a planned route.

6. The method of claim 5 wherein driver errors include missing a turn or highway exit, turning at a wrong location or in a wrong direction, taking a wrong highway exit, and driving past a selected final destination.

7. The method of claim 1 wherein navigation error data includes date and time, roadway location of the vehicle, type of error, information about the vehicle, driver identification, vehicle speed, roadway properties, road conditions and traffic conditions.

8. The method of claim 1 wherein analyzing the navigation error data includes using machine learning techniques.

9. The method of claim 1 wherein patterns in the navigation errors include patterns of errors made by an individual driver and patterns of errors made at a particular roadway location.

10. The method of claim 1 wherein adaptations in guidance include increasing or decreasing a number of notifications to a driver, changing timing of the notifications, recommending a change of vehicle speed or lane position, and adding supplemental explanation of an upcoming maneuver.

11. The method of claim 1 wherein the method is applied to routing for location-based services promotions.

12. A method for providing adaptive guidance for driver navigation, said method comprising:

recording navigation error data for navigation errors detected by a navigation system in a vehicle, where navigation errors include navigation system errors and driver errors, and driver errors are detected by route recalculation, driver request for more information, or departure from a planned route;

communicating the navigation error data to a server computer;

analyzing the navigation error data on the server computer to detect patterns in the navigation errors, including patterns of errors made by an individual driver and patterns of errors made at a particular roadway location;

incorporating information about the patterns in the navigation errors as a property in a route planning system; and

providing adaptive driver navigation guidance from the route planning system, where adaptations in guidance are made based on the patterns in the navigation errors.

13. The method of claim 12 wherein navigation error data includes date and time, roadway location of the vehicle, type of error, information about the vehicle, driver identification, vehicle speed, roadway properties, road conditions and traffic conditions.

14. The method of claim 12 wherein adaptations in guidance include increasing or decreasing a number of notifications to a driver, changing timing of the notifications, recommending a change of vehicle speed or lane position, and adding supplemental explanation of an upcoming maneuver.

15. A system for providing adaptive guidance for driver navigation, said system comprising:

a plurality of vehicles each equipped with a navigation system configured to detect navigation errors and record navigation error data for the errors;

an error analyzer which receives the navigation error data from the navigation systems in the plurality of vehicles, said error analyzer being configured to detect patterns in the navigation errors; and

a route planner configured to provide adaptive driver navigation guidance, where adaptations in guidance are made based on the patterns in the navigation errors.

16. The system of claim 15 wherein navigation errors include navigation system errors and driver errors, and driver errors are detected by route recalculation, driver request for more information, or departure from a planned route.

17. The system of claim 15 wherein navigation error data includes date and time, roadway location of the vehicle, type of error, information about the vehicle, driver identification, vehicle speed, roadway properties, road conditions and traffic conditions.

18. The system of claim 15 wherein patterns in the navigation errors include patterns of errors made by an individual driver and patterns of errors made at a particular roadway location.

19. The system of claim 15 wherein adaptations in guidance include increasing or decreasing a number of notifications to a driver, changing timing of the notifications, recommending a change of vehicle speed or lane position, and adding supplemental explanation of an upcoming maneuver.

20. The system of claim 15 wherein the system is applied to routing for location-based services and promotions.
