Abstract

Embodiments for driver confidence evaluation while operating a vehicle by a processor. Driver confidence, based upon one or more psychophysical parameters of a driver, is combined and correlated with a plurality of environmental factors and route information. A confidence in vehicular operational capabilities of the driver may be detected according to the correlation.

First claim

The invention claimed is:

1. A method, by a processor, for driver competency evaluation while operating a vehicle, comprising:
correlating driver confidence, based upon one or more psychophysical parameters of a driver, with a plurality of environmental factors and route information;
detecting a competency in vehicular operational capabilities of the driver according to the correlation; wherein detecting the competency includes identifying an anxiety road profile value determined by measuring the one or more psychophysical parameters associated with the route information of a particular travel route; and
performing one of a plurality of suggested confidence actions according to the detected competency to improve the vehicular operational capabilities through use of a user interface, thereby increasing driver safety while operating the vehicle; wherein performing one of the plurality of confidence actions further comprises performing at least one of:
providing at least one suggestion to increase the driver confidence or correct the confidence in the vehicular operational capabilities; and
providing customized travel routes for the driver to reduce the driver confidence.

2. The method of claim 1 , further including monitoring the one or more psychophysical parameters, wherein the one or more psychophysical parameters include at least a heart rate, blood pressure, or electro dermal activity.

3. The method of claim 1 , further including identifying a plurality of routes associated with a current location of the driver or target destination as eligible routes matching the vehicular operational capabilities.

4. The method of claim 1 , further including analyzing the route information and the plurality of environmental factors according to a knowledge domain for the correlation, wherein data relating to the correlation is stored in a driver profile for the driver.

5. The method of claim 1 , further including determining the driver confidence by comparing the one or more psychophysical parameters with a route associated with a current location of the vehicle or target destination and at least one of the plurality of environmental factors.

6. A system for driver confidence evaluation while operating a vehicle, comprising:
one or more computers with executable instructions that when executed cause the system to:
correlate driver confidence, based upon one or more psychophysical parameters of a driver, with a plurality of environmental factors and route information;
detect a competency in vehicular operational capabilities of the driver according

to the correlation; wherein detecting the competency includes identifying an anxiety road profile value determined by measuring the one or more psychophysical parameters associated with the route information of a particular travel route; and
perform one of a plurality of suggested confidence actions according to the detected competency to improve the vehicular operational capabilities through use of a user interface, thereby increasing driver safety while operating the vehicle; wherein performing one of the plurality of confidence actions further comprises performing at least one of:
providing at least one suggestion to increase the driver confidence or correct the confidence in the vehicular operational capabilities; and
providing customized travel routes for the driver to reduce the driver confidence.

7. The system of claim 6 , wherein the executable instructions monitor the one or more psychophysical parameters, wherein the one or more psychophysical parameters include at least a heart rate, blood pressure, or electro dermal activity.

8. The system of claim 6 , wherein the executable instructions identify a plurality of routes associated with a current location of the driver or target destination as eligible routes matching the vehicular operational capabilities.

9. The system of claim 6 , wherein the executable instructions analyze the route information and the plurality of environmental factors according to a knowledge domain for the correlation, wherein data relating to the correlation is stored in a driver profile for the driver.

10. The system of claim 6 , wherein the executable instructions determine the driver confidence by comparing the one or more psychophysical parameters with a route associated with a current location of the vehicle or target destination and at least one of the plurality of environmental factors.

11. A computer program product for driver confidence evaluation while operating a vehicle by a processor, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
an executable portion that correlates driver competency, based upon one or more psychophysical parameters of a driver, with a plurality of environmental factors and route information;
an executable portion that detects a competency in vehicular operational capabilities of the driver according to the correlation; wherein detecting the competency includes identifying an anxiety road profile value determined by measuring the one or more psychophysical parameters associated with the route information of a particular travel route; and
an executable portion that performs one of a plurality of suggested confidence actions according to the detected competency to improve the vehicular operational capabilities through use of a user interface, thereby increasing driver safety while operating the vehicle; wherein performing one of the plurality of confidence actions further comprises performing at least one of:
providing at least one suggestion to increase the driver confidence or correct the confidence in the vehicular operational capabilities; and
providing customized travel routes for the driver to reduce the driver confidence.

12. The computer program product of claim 11 , further including an executable portion that monitors the one or more psychophysical parameters, wherein the one or more psychophysical parameters include at least a heart rate, blood pressure, or electro dermal activity.

13. The computer program product of claim 11 , further including an executable portion that identifies a plurality of routes associated with a current location of the driver or target destination as eligible routes matching the vehicular operational capabilities.

14. The computer program product of claim 11 , further including an executable portion that analyzes the route information and the plurality of environmental factors according to a knowledge domain for the correlation, wherein data relating to the correlation is stored in a driver profile for the driver.

15. The computer program product of claim 11 , further including an executable portion that determines the driver confidence by comparing the one or more psychophysical parameters with a route associated with a current location of the vehicle or target destination and at least one of the plurality of environmental factors.
