Abstract

A method for supplying information to a driver of a vehicle is provided. The preferred method includes estimating a cognitive load on the driver, sensing information for the driver, selecting information based on the estimated cognitive load, and supplying the selected information to the driver.

Claims

1. A method for supplying information to a driver of a vehicle in an environment, comprising:

estimating a cognitive load on the driver;

sensing information for the driver;

selecting information based on the estimated cognitive load; and

supplying the selected information to the driver.

2. The method according to claim 1 wherein said estimating a cognitive load includes collecting a vehicle factor.

3. The method according to claim 2 wherein said collecting a vehicle factor includes collecting the vehicle speed of the vehicle.

4. The method according to claim 3 wherein said collecting a vehicle factor further includes collecting the interior noise of the vehicle.

5. The method according to claim 4 wherein said collecting a vehicle factor includes collecting historical data of the vehicle.

6. The method according to claim 1 wherein said estimating a cognitive load includes collecting an environmental factor.

7. The method according to claim 6 wherein said collecting an environment factor includes collecting the weather condition of the environment.

8. The method according to claim 7 wherein said collecting an environmental factor further includes collecting the road condition of the environment.

9. The method according to claim 8 wherein said collecting an environmental factor further includes collecting the road complexity of the environment.

10. The method according to claim 9 wherein said collecting an environmental factor includes collecting the historical data of the environment.

11. The method according to claim 1 wherein said estimating a cognitive load includes collecting a driver factor.

12. The method according to claim 11 wherein said collecting a driver factor includes collecting the historical data of the driver.

13. The method according to claim 1 wherein said selecting information includes selecting information from the sensed information.

14. The method according to claim 1 wherein said sensing information includes sensing vehicle performance information.

15. The method according to claim 1 wherein said sensing information includes sensing vehicle position information.

16. The method according to claim 1 wherein said sensing information includes sensing engine performance information.

17. The method according to claim 1 wherein said sensing information includes sensing climate control information.

18. The method according to claim 1 wherein said sensing information includes sensing audio control information.

19. The method according to claim 1 wherein said sensing information includes sensing driver usage information.

20. The method according to claim 1 wherein said sensing information includes sensing vehicle warning information.

21. The method according to claim 1 wherein said estimating a cognitive load includes collecting several factors, normalizing the collected factors, weighting the normalized factors, and summing the weighted factors.

22. The method according to claim 21 wherein said selecting information further includes comparing the summed factor to a predetermined value and selecting only a portion of the sensed information if the summed value is greater than the predetermined value.

23. The method according to claim 1 wherein said supplying the selected information includes visually supplying the selected information to the driver.

24. The method according to claim 23 wherein said supplying the selected information further includes aurally supplying the selecting information to the driver.

25. The method according to claim 1 wherein said supplying the selected information further includes aurally supplying the selecting information to the driver.
