Abstract

A method (600) of synthesizing a response to an operating situation of a vehicle includes the step of generating a master condition list (602), determining the existence of an operating situation (604), determining an operator cognitive load (606) and determining a response to the operating situation based in part on the master condition list and the operator cognitive load (608). The master condition list is a fusion of sensor data gathered within and around the vehicle. The operator cognitive load is a measure of the operator'"'"'s ability to handle tasks within the vehicle.

Claims

1. A method of synthesizing a response to an operating situation of a vehicle;

the method comprising the steps of;

generating a master condition list, the master condition list being a fusion of sensor data within the vehicle;

determining the existence of an operating situation based on the master condition list;

determining a driver cognitive load based upon the master condition list; and

determining a response to the operating situation in view of the operator cognitive load and the operating situation.

2. The method of claim 1, wherein the sensor data comprises vehicle operating data.

3. The method of claim 1, wherein the sensor data comprises operator activity data.

4. The method of claim 1, wherein the sensor data comprises environment data.

5. The method of claim 1, wherein the sensor data comprises operator condition data.

6. The method of claim 1, wherein the sensor data comprises operator preference data.

7. The method of claim 1, wherein the sensor data comprises driver action feedback data.

8. The method of claim 1, wherein the step of determining the existence of an operating situation comprises determining the existence of a problem condition.

9. The method of claim 1, wherein the step of determining the existence of an operating situation comprises determining the existence of a problem correction.

10. The method of claim 1, wherein the step of determining the existence of an operating situation comprises determining the existence of a problem exacerbation.

11. The method of claim 1, wherein the step of determining the existence of an operating situation comprises determining the existence of an operator task requirement.

12. The method of claim 1, wherein the step of determining the existence of an operating situation comprises determining the existence of an agent task requirement.

13. The method of claim 1, wherein the step of determining the existence of an operating situation comprises determining the existence of a completion of an operator task.

14. The method of claim 1, wherein the step of determining the existence of an operating situation comprises determining the existence of a completion of an agent task.

15. The method of claim 1, wherein the step of determining a response to the operating situation comprises synchronizing an information flow to an operator of the vehicle.

16. The method of claim 1, wherein the step of determining a response to the operating situation comprises generating an alert to the driver.

17. The method of claim 1, wherein the alert comprises one of an audio alert, a visual alert and a haptic alert.

18. The method of claim 1, wherein the step of determining a response to the operating situation comprises terminating operation of selected services within the vehicle.
