Abstract

A device and a corresponding method including a vehicle data recording section having a plurality of vehicle operating characteristic sensors, a main system controller, and an event data recorder subservient to the main system controller. Also included in the device is a driver action recording section including at least one driver action sensor, a driver action system controller not subservient to the main system controller, and a driver action recorder. The at least one driver action sensor obtains information regarding actions of a driver of the vehicle concurrently with at least one of the plurality of vehicle operating characteristic sensors such that sensor data corresponding to an event is obtained independently by each of the vehicle data recording section and the driver action recording section.

Claims

1. A system, comprising:

a vehicle data recording section including;

a plurality of vehicle operating characteristic sensors configured to obtain information regarding operation of a vehicle,

a main system controller configured to control operation of the vehicle, and

an event data recorder subservient to the main system controller and configured to record data obtained by the plurality of vehicle operating characteristic sensors; and

a driver action recording section including;

at least one driver action sensor configured to obtain information regarding actions of a driver of the vehicle,

a driver action system controller not subservient to the main system controller and configured to control operation of the driver action recording section, and

a driver action recorder configured to record data obtained by the at least one driver action sensor,

wherein the at least one driver action sensor obtains information regarding actions of a driver of the vehicle concurrently with at least one of the plurality of vehicle operating characteristic sensors obtaining information of an operating characteristic triggered by the actions of the driver of the vehicle such that sensor data corresponding to an event is obtained independently by each of the vehicle data recording section and the driver action recording section.

2. The system according to claim 1, wherein the at least one driver action sensor is at least one of a camera/illuminator pair and a tactile sensor.

3. The system according to claim 2, wherein the at least one driver action sensor includes a plurality of tactile sensors.

4. The system according to claim 1, wherein the at least one driver action sensor includes at least one tactile sensor disposed in a brake pedal or an accelerator pedal.

5. The system according to claim 1, wherein the at least one driver action sensor includes a camera/illuminator pair attached to the arm of a brake pedal or accelerator pedal.

6. The system according to claim 1, wherein the at least one driver action sensor includes a camera/illuminator pair attached above a brake pedal or accelerator pedal to a housing of the vehicle.

7. The system according to claim 1, wherein the at least one driver action sensor includes a camera/illuminator pair attached above a brake pedal or accelerator pedal and hidden in a housing of the vehicle.

8. The system according to claim 1, wherein the driver action recorder is further configured to record data obtained by the at least one driver action sensor for a predetermined amount of time before overwriting the obtained data.

9. The system according to claim 8, wherein the overwriting of the obtained data is halted in response to an event.

10. The system according to claim 8, wherein the event is a vehicle accident.

11. A method, comprising:

obtaining information regarding operation of a vehicle via a plurality of vehicle operating characteristic sensors;

controlling operation of the vehicle using a main system controller;

recording data obtained by the plurality of vehicle operating characteristic sensors using an event data recorder subservient to the main system controller;

obtaining information regarding actions of a driver of the vehicle via at least one driver action sensor, the at least one driver action sensor obtaining information regarding actions of a driver of the vehicle concurrently with at least one of the plurality of vehicle operating characteristic sensors obtaining information of an operating characteristic triggered by the actions of the driver of the vehicle;

recording data obtained by the at least one driver action sensor using a driver action recorder such that sensor data corresponding to an event is obtained independently by each of the event data recorder and the driver action recorder; and

controlling operation of the driver action recorder using a driver action system controller not subservient to the main system controller.

12. The method according to claim 11, wherein the at least one driver action sensor is at least one of a camera/illuminator pair and a tactile sensor.

13. The method according to claim 12, wherein the at least one driver action sensor includes a plurality of tactile sensors.

14. The method according to claim 11, wherein the at least one driver action sensor includes at least one tactile sensor disposed in a brake pedal or an accelerator pedal.

15. The method according to claim 11, wherein the at least one driver action sensor includes a camera/illuminator pair attached to the arm of a brake pedal or accelerator pedal.

16. The method according to claim 11, wherein the at least one driver action sensor includes a camera/illuminator pair attached above a brake pedal or accelerator pedal to a housing of the vehicle.

17. The method according to claim 11, wherein the at least one driver action sensor includes a camera/illuminator pair attached above a brake pedal or accelerator pedal and hidden in a housing of the vehicle.

18. The method according to claim 11, further comprising:

recording data obtained by the at least one driver action sensor for a predetermined amount of time before overwriting the obtained data using the driver action recorder.

19. The method according to claim 18, wherein the overwriting of the obtained data is halted in response to an event.

20. The method according to claim 18, wherein the event is a vehicle accident.

21. A non-transitory computer readable storage medium having stored thereon a program that when executed by a computer causes the computer to execute a method comprising:

obtaining information regarding operation of a vehicle via a plurality of vehicle operating characteristic sensors;

controlling operation of the vehicle using a main system controller;

recording data obtained by the plurality of vehicle operating characteristic sensors using an event data recorder subservient to the main system controller;

obtaining information regarding actions of a driver of the vehicle via at least one driver action sensor, the at least one driver action sensor obtaining information regarding actions of a driver of the vehicle concurrently with at least one of the plurality of vehicle operating characteristic sensors obtaining information of an operating characteristic triggered by the actions of the driver of the vehicle;

recording data obtained by the at least one driver action sensor using a driver action recorder such that sensor data corresponding to an event is obtained independently by each of the event data recorder and the driver action recorder; and

controlling operation of the driver action recorder using a driver action system controller not subservient to the main system controller.
