Abstract

A system includes a primary vehicle operable by a driver. The driver is associated with a first device having a plurality of features with which the driver may interact. The system further includes a second device integral with the primary vehicle and in communication with the first device. The second device is configured to detect an interaction between the driver and at least one of the features of the first device, and calculate a driver distraction level based upon the interaction between the driver and the at least one feature of the first device.

First claim

What is claimed is:

1. A system, comprising:
a primary vehicle operable by a driver, the driver being associated with a first device having a plurality of features with which the driver may interact;
at least one range-sensitive antenna installed in a steering wheel of the primary vehicle for measuring a distance between the steering wheel and the first device; and
a second device integral with the primary vehicle and in communication with the first device and the at least one range-sensitive antenna, the second device being configured to:
detect an interaction between the driver and at least one of the plurality of features of the first device,
detect a load on a steering column of the primary vehicle, and
calculate a driver distraction level based at least upon: the interaction between the driver and the at least one of the plurality of features of the first device, the distance between the steering wheel and the first device, and the detected load.

2. The system of claim 1 , wherein the second device is further configured to broadcast the driver distraction level.

3. The system of claim 2 , wherein the driver distraction level is broadcast as a component of a basic safety message (BSM).

4. The system of claim 2 , wherein the broadcast is receivable by a vehicle to pedestrian (V2P) communication device associated with at least one of a secondary vehicle and a pedestrian.

5. The system of claim 1 , wherein the second device is a vehicle to pedestrian (V2P) communication device.

6. The system of claim 1 , further comprising a vehicle safety system, the vehicle safety system being actuated in response to the driver distraction level exceeding a threshold level.

7. The system of claim 6 , wherein the vehicle safety system comprises at least one of a lane tracking system, a human machine interface (HMI), a braking system, an audible alert system, and a visual alert system.

8. The system of claim 1 , further comprising a proximity sensor mounted to the primary vehicle, the proximity sensor being configured to detect the location of the first device relative to the driver.

9. The system of claim 1 , further comprising a heart rate monitor for determining a heart rate of the driver, wherein the driver distraction level is further based upon the heart rate of the driver.

10. The system of claim 1 , further comprising a driver facing camera for detecting an emotional state of the driver, wherein the driver distraction level is further based upon the emotional state of the driver.

11. A method, comprising:
detecting a first device, the first device having a plurality of features with which a driver of a primary vehicle may interact;
measuring a distance between a steering wheel of the primary vehicle and the first device via at least one range-sensitive antenna installed in the steering wheel;
monitoring with a second device an interaction between the driver and at least one of the plurality of features of the first device;
detecting a load on a steering column of the primary vehicle; and
calculating a driver distraction level based at least upon: the interaction between the driver and the at least one of the plurality of features of the first device, the distance between the steering wheel and the first device, and the detected load.

12. The method of claim 11 , further comprising broadcasting the driver distraction level.

13. The method of claim 12 , wherein the driver distraction level is broadcast as a component of a basic safety message (BSM).

14. The method of claim 12 , wherein the broadcast is receivable by a vehicle to pedestrian (V2P) communication device associated with at least one of a secondary vehicle and a pedestrian.

15. The method of claim 11 , wherein the second device is a vehicle to pedestrian (V2P) communication device.

16. The method of claim 11 , further comprising:
comparing the driver distraction level with a threshold level; and
actuating a vehicle safety system in response to the driver distraction level exceeding the threshold level.

17. The method of claim 16 , wherein the vehicle safety system comprises at least one of a lane tracking system, a human machine interface (HMI), a braking system, an audible alert system, and a visual alert system.

18. The method of claim 11 , further comprising determining with a proximity sensor mounted to the primary vehicle the location of the first device relative to the driver.

19. The method of claim 11 , further comprising measuring with a heart rate monitor the heart rate of the driver, wherein the step of calculating the driver distraction level is further based upon the heart rate of the driver.

20. The method of claim 11 , further comprising detecting with a driver facing camera an emotional state of the driver, wherein the step of calculating the driver distraction level is further based upon the emotional state of the driver.
