Abstract

A Driver Risk Assessment System and Method Employing Selectively Automatic Event Scoring. The system and method provides robust and reliable event scoring and reporting, while also optimizing data transmission bandwidth. The system includes onboard vehicular driving event detectors that record data related to detected driving events, selectively store or transfer data related to said detected driving events. If elected, the onboard vehicular system will score a detected driving event, compare the local score to historical values previously stored within the onboard system, and upload selective data or data types to a remote server or user if the system concludes that a serious driving event has occurred. The system may further respond to independent user requests by transferring select data to said user at a variety of locations and formats.

Claims

1. A system for determining a driving event, comprising:

an event capture device associated with a vehicle for detecting data related to the vehicle, wherein the data related to the vehicle comprises regularly uploaded data and selectively uploaded data;

an event detector coupled to the vehicle for;

generating an event score based on the data related to the vehicle; and

determining whether the event score meets a pre-determined criteria; and

an event data management module for;

in the event that the event score meets the pre-determined criteria, determining that the driving event has occurred; and

uploading the selectively uploaded data to a remote computer device based on the determination that the driving event has occurred.

2. The system of claim 1, wherein the uploading is further responsive to a data request received by the event detector.

3. The system of claim 2, wherein the data request received by the event detector is sent from the remote computer device.

4. The system of claim 1, wherein the data comprises audio, video, or telemetry data.

5. The system of claim 1, wherein the event score is calculated using a first set of data selected from a group of data representing vehicle velocity, vehicle acceleration, vehicle special orientation, vehicle directional heading, vehicle metadata, and vehicle location.

6. The system of claim 5, wherein the event score is calculated excluding the selectively uploaded data.

7. The system of claim 1, wherein the uploading is further responsive to a user request.

8. The system of claim 1, wherein the determining whether the event score meets a pre-determined criteria comprises comparing the event score with a group of previously stored event scores, and the event data management module uploads the selectively uploaded data in the event the comparison so dictates.

9. The system of claim 8, wherein the group of previously stored event scores comprises a set of representative event scores stored in a local data repository associated with the event detector.

10. The system of claim 1, wherein the event capture device repeatedly generates data.

11. The system of claim 1, wherein the event capture device is one of a plurality of event capture devices.

12. A method for determining a driving event, comprising:

detecting data related to the vehicle using an event capture device associate with a vehicle, wherein the data comprises regularly uploaded data and selectively uploaded data;

generating, using an event detector coupled to the vehicle, an event score based on the data related to the vehicle,

determining whether the event score meets a pre-determined criteria;

in the event that the event score meets the pre-determined criteria, determining that the driving event has occurred; and

uploading the selectively uploaded data using an event data management module to a remote computer device based on the determination that the driving event has occurred.

13. The method of claim 12, wherein the uploading is further responsive to a data request received by the event detector.

14. The method of claim 13, wherein the data request received by the event detector is sent from the remote computer device.

15. The method of claim 12, wherein the data comprises audio, video, or telemetry data.

16. The method of claim 12, wherein the event score is calculated using a a first set of data selected from a group of data representing vehicle velocity, vehicle acceleration, vehicle special orientation, vehicle directional heading, vehicle metadata, and vehicle location.

17. The method of claim 16, wherein the event score is calculated excluding the selectively uploaded data.

18. The method of claim 12, wherein the uploading is further responsive to a user request.

19. The method of claim 12, wherein determining whether the event score meets a pre-determined criteria further comprises comparing the event score with a group of previously stored event scores, and uploading the selectively uploaded data in the event the comparison so dictates.
