Abstract

Vehicle lane changing monitor functions are implemented by a lane sensor disposed in a vehicle, a gaze detection sensor disposed in the vehicle, and a computer processor embedded in the vehicle. Logic that is executable by the computer processor implements a method. The method includes receiving data, from the lane sensor, indicating an occurrence of a lane shifting event that indicates the vehicle is drifting away from a vehicle lane. The method further includes monitoring biometric data received from the gaze detection sensor and, upon determining a gaze change event has not occurred within a threshold period of time with respect to the lane shifting event, a corrective action within the vehicle is initiated.

Claims (40)

1. A system, comprising:

at least one lane sensor disposed in a vehicle;

a gaze detection sensor disposed in the vehicle;

a computer processor embedded in the vehicle, the computer processor communicatively coupled to the at least one lane sensor and the gaze detection sensor; and

logic executable by the computer processor, the logic configured to implement a method, the method comprising:

receiving data, from the at least one lane sensor, indicating an occurrence of a lane shifting event, the lane shifting event indicating the vehicle is drifting away from a vehicle lane;

monitoring biometric data received from the gaze detection sensor;

upon determining a gaze change event has not occurred within a threshold period of time with respect to the lane shifting event, initiating a corrective action within the vehicle;

storing data relating to the lane shifting event and the gaze change event in a log file in a memory device of the vehicle;

generating a report from the log file, the report directed to driving behavior of an operator of the vehicle; and

providing access to the report to an authorized entity.

2. The system of claim 1 , wherein the computer processor is communicatively coupled to the at least one lane sensor and the gaze detection sensor via a vehicle network.

3. The system of claim 1 , wherein the lane shifting event is determined using a drifting metric as a function of time.

4. The system of claim 1 , wherein the biometric data indicates eye positions detected for the operator of the vehicle.

5. The system of claim 1 , wherein the corrective action is a notification presented to an operator of the vehicle, the notification implemented as at least one of an audio signal and a visual signal delivered through the vehicle.

6. The system of claim 5 , wherein the audio signal is a voice message requesting the operator check at least one vehicle mirror before completing a lane change.

7. The system of claim 1 , wherein the corrective action includes activating an anti-drift control device on the vehicle, the anti-drive control device configured to return the vehicle to the vehicle lane.

8. The system of claim 1 , wherein the authorized entity comprises at least one of an owner of the vehicle, the operator of the vehicle and an insurer of the vehicle, and a government agency.

9. The system of claim 1 , wherein the providing access to the report to the authorized entity comprises transmitting the report to the authorized entity over a network.

10. A method, comprising:

receiving, from at least one lane sensor disposed in a vehicle, data indicating an occurrence of a lane shifting event, the lane shifting event indicating the vehicle is drifting away from a vehicle lane;

monitoring, by a computer processor embedded in the vehicle, biometric data received from a gaze detection sensor in the vehicle; to determine whether an operator of the vehicle has checked at least one vehicle mirror;

upon determining the operator has not checked the at least one vehicle mirror within a threshold period of time with respect to the lane shifting event, initiating a corrective action within the vehicle;

storing data relating to the lane shifting event and the determination of whether the operator checked the vehicle mirror in a log file in a memory device of the vehicle;

generating a report from the log file, the report directed to an operator's driving behavior with respect to use of vehicle mirrors when performing lane changes; and providing access to the report to an authorized entity.

11. The method of claim 10 , wherein the computer processor is communicatively coupled to the at least one lane sensor and the gaze detection sensor via a vehicle network.

12. The method of claim 10 , wherein the lane shifting event is determined using a drifting metric as a function of time.

13. The method of claim 10 , wherein the biometric data indicates eye positions detected for the operator of the vehicle.

14. The method of claim 10 , wherein the authorized entity comprises at least one of an owner of the vehicle, the operator of the vehicle and an insurer of the vehicle, and a government agency.

15. The method of claim 10 , wherein the providing access to the report to the authorized entity comprises transmitting the report to the authorized entity over a network.

16. A computer program product, the computer program product comprising a storage medium having computer program instructions embodied thereon, which when executed by a computer processor, cause the computer processor to implement a method, the method comprising:

receiving, from at least one lane sensor disposed in a vehicle, data indicating an occurrence of a lane shifting event, the lane shifting event indicating the vehicle is drifting away from a vehicle lane;

monitoring biometric data received from a gaze detection sensor;

upon determining a gaze change event has not occurred within a threshold period of time with respect to the lane shifting event, initiating a corrective action within the vehicle;

storing data relating to the lane shifting event and the gaze change event in a log file in a memory device of the vehicle;

generating a report from the log file, the report directed to patterns of behavior of an operator of the vehicle during driving the vehicle; and

providing access to the report to an authorized entity.

17. The computer program product of claim 16 , wherein the biometric data indicates eye positions detected for the operator of the vehicle.

18. The computer program product of claim 16 , wherein the authorized entity comprises at least one of an owner of the vehicle, the operator of the vehicle and an insurer of the vehicle, and a government agency.

19. The computer program product of claim 16 , wherein the providing access to the report to the authorized entity comprises transmitting the report to the authorized entity over a network.
