Abstract

Methods and systems are provided for responding to drowsiness of a driver. The method and system comprise detecting by a module the drowsiness of the driver based on a detected level exceeding a threshold associated with at least one of a set of conditions of the driver which indicate the drowsiness of the driver. The conditions of driver drowsiness include driver performance, vigilance, judgment and alertness. A response to the conditions which have been detected is provided by assists to the driver to at least facilitate reducing the detected level below the threshold associated with the conditions and any subsequent drowsiness of the driver.

Claims

1. A method for responding to drowsiness of a driver, the method comprising:

detecting, by a module, the drowsiness based on a detected level exceeding a threshold associated with at least one of a set of conditions of the driver which indicate the drowsiness of the driver, the conditions comprise driver performance, vigilance, judgment and alertness; and

responding to the conditions which have been detected by providing assists to the driver to at least facilitate reducing the detected level below the threshold associated with the conditions and any subsequent drowsiness associated therewith wherein the assists comprise a plurality of tasks which are automated tasks which comprise;

passive, interactive and external assists for providing countermeasures to reduce the detected level of the condition of drowsiness.

3. The method of claim 1, wherein in a next responding step:

the method further comprises;

escalating a response, if the detected level either increases or is not reduced of the condition associated with the drowsiness of the driver by selecting another assist or a combination of assists from a plurality of assists comprising passive assists, interactive assists and external assists.

2. (canceled)

4. The method of claim 2, wherein the passive assists further comprise tasks not requiring a response on the part of the driver in an attempt to at least facilitate reducing the detected level of conditions of driver drowsiness.

5. The method of claim 2, wherein the passive assists comprise notifications sent to the driver which further comprise:

a subliminal or auditory cue, a flashing of an interior light, a comfort setting change, information about localities, and a driver seatbelt action.

6. The method of claim 2, wherein the interactive assists comprise tasks requiring a response on the part of the driver in an attempt to at least facilitate reducing the detected level of conditions of driver drowsiness.

7. The method of claim 2, wherein the interactive assists comprise tasks of the driver which requiring a response which further comprise:

altering a primary control of the vehicle, posing an audible question, requiring a secondary task, and using phone calling features.

8. The method of claim 2, wherein the external assists comprise tasks requiring a response on the part of the driver to converse with third parties for assistance or intervention, in an attempt by communications with the driver either, to at least facilitate reducing the detected level of the condition of driver drowsiness or to intercede in a driving activity.

9. A computer program product tangibly embodied in a non-transitory computer-readable storage device and comprising instructions that when executed by a processing module perform a method for responding to conditions of driver drowsiness, the method comprising:

detecting, by a processing module, the drowsiness based on a detected level exceeding a threshold associated with at least one of a set of conditions of the driver which indicate the drowsiness of the driver, the conditions comprise driver performance, vigilance, judgment and alertness; and

responding to the conditions which have been detected by providing assists to the driver to at least facilitate reducing the detected level below the threshold associated with the conditions and any subsequent drowsiness associated therewith wherein the assists are a plurality of tasks which are automated tasks which comprise;

passive, interactive and external assists for providing countermeasures to reduce the detected level of the condition of drowsiness.

11. The method of claim 9, wherein in a next responding step:

the method further comprises;

escalating a response, if the detected level either increases or is not reduced of the condition associated with the drowsiness of the driver by selecting another assist or a combination of assists from a plurality of assists comprising passive assists, interactive assists and external assists.

10. (canceled)

12. The method of claim 10, wherein the passive assists further comprise tasks not requiring a responsive action on the part of the driver in an attempt to reduce the detected level of conditions of driver drowsiness.

13. The method of claim 10, wherein the passive assists comprise notifications sent to the driver which further comprise:

a subliminal or auditory cue, a flashing of an interior light, a comfort setting change, information of localities, and a driver seatbelt action.

14. The method of claim 10, wherein the interactive assists comprise tasks requiring a responsive action on the part of the driver in an attempt to reduce the detected level of conditions of driver drowsiness.

15. The method of claim 10, wherein the interactive assists comprise tasks requiring a responsive action which further comprise:

altering a primary control of the vehicle, posing an audible question, requiring a secondary task, and using phone calling features.

16. The method of claim 10, wherein the external assists comprise tasks requiring a responsive action on the part of the driver to converse with third parties for assistance or intervention, in an attempt by communications with the driver either to reduce the detected level of the condition of driver drowsiness or to intercede in a driving activity.

17. A system comprising:

at least one processor; and

at least one computer-readable storage device comprising instructions that when executed causes performance of a method for providing countermeasures for driver drowsiness, the method comprising;

determining, using information provided by one or more sensors of a vehicle, a level exceeding a threshold for a condition associated with driver drowsiness wherein the information provided by the sensors is at least of driver performance, vigilance, judgement or alertness with respect to vehicle operations; and

responding to the condition associated with driver drowsiness by providing a plurality of countermeasures to at least facilitate reducing the level below the threshold for the condition of driver drowsiness wherein;

the countermeasures comprise a plurality of passive, interactive, and external vehicle assists for reducing a detected level of the condition of the driver drowsiness.

18. The system of claim 17, wherein in a next responding step:

the method further comprises;

escalating by responding, if the level either increases or is not reduced of the condition associated with the drowsiness of the driver by selecting another assist or a combination of assists from the plurality of assists according to a particular scheme.

19. The system of claim 18, wherein the step of selecting further comprises:

selecting, in conjunction with context sensing and monitoring information derived from the sensors of vehicle, additional assists from the plurality of assists for reducing the condition associated with the drowsiness of the driver.

20. The system of claim 17, wherein the passive assists further comprise demands not requiring a responsive action on the part of the driver in an attempt to reduce the level of the condition of driver drowsiness.
