Abstract

Disclosed are methods and apparatus for using black box data to analyze vehicular accidents. The methods include obtaining information from an event data recorder associated with a vehicle and using the data obtained therefrom in determining and analyzing the vehicular accident. Attributes to be analyzed include impact severity, change in velocity, and other desired parameters. Further disclosed are methods to securely communicate the downloaded black box information to a secure location for later analysis and processing.

Claims

1. A computer-implemented method for analyzing a collision between a first vehicle and a second vehicle, comprising:

receiving information obtained from an event data recorder of said first vehicle that records black box information, at a computer system remote from the first vehicle and the second vehicle;

determining an impact severity of said first and second vehicles in the computer system using said information, the impact severity including a change in velocity for the first and second vehicles, by modeling the impact severity in the computer system using the Information; and

reporting the impact severity from the computer system.

2. The method of claim 1, wherein said information comprises a change in velocity of said first vehicle, and further comprising calibrating said change in velocity prior to using said information.

3. The method of claim 1, said receiving comprising receiving said information via a network of interconnected computers or via wireless transmission.

4. The method of claim 1, further comprising storing said information in a secure manner.

5. The method of claim 1, further comprising comparing said impact severity determined from said information to a second determination of impact severity, said second determination calculated in said computer system without said information.

6. The method of claim 1, wherein said information comprises a change in velocity and a pre-impact speed of said first vehicle.

7. The method of claim 1, further comprising using the information in the computer system in connection with a database of vehicle data including benchmark data for a benchmark vehicle related to one of the first or second vehicles to determine the impact severity of the one of the first or second vehicles.

8. The method of claim 1, further comprising using the information in the computer system in connection with repair estimate information for at least one of the first and second vehicles.

9. The method of claim 1, further comprising determining a point of impact and a principal direction of force for each of the first and second vehicles.

10. The method of claim 5, further comprising weighting said impact severity determined from said information differently than the second determination of impact severity.

11. The method of claim 6, wherein using said information comprises determining a change in velocity of said second vehicle based on said change in velocity and said pre-impact speed of said first vehicle.

12. The method of claim 6, wherein using said information further comprises determining a relative velocity of said first and second vehicles based on said change in velocity of said first vehicle.

13. The method of claim 9, further comprising determining the impact severity of at least one of the first and second vehicles using the determined point of impact and the determined principal direction of force.

14. The method of claim 11, further comprising adjusting said change in velocity of said first vehicle prior to using said information.

15. A computer-implemented method for determining impact severity of a collision between a first vehicle and a second vehicle, comprising:

receiving information obtained from an event data recorder of said first vehicle that records black box data, during a claim evaluation process;

electronically storing said information on a storage medium, said information comprising the black box data;

electronically accessing said information from said storage medium;

selecting one of different algorithms to use in modeling said impact severity based on a type of said event data recorder, wherein the selection is further based on a type or characteristics of information provided by the type of event data recorder;

utilizing said information in a computer to model said impact severity via the selected algorithm; and

reporting the impact severity from the computer.

16. The method of claim 15, wherein said information comprises a change in velocity of said first vehicle;

and wherein said modeling is based at least in part on said change in velocity.

17. The method of claim 15, further comprising performing a simulation to generate a distribution of change in velocity calculations for said first vehicle using said information.

18. The method of claim 17, further comprising determining if said distribution is consistent with at least one user input.

19. A computer-implemented method for assessing an accident involving a first vehicle, comprising:

receiving black box information obtained from an event data recorder of said first vehicle;

extracting non-visual data from said black box information;

determining a first measure of impact severity by modeling the impact severity using said non-visual data in a system external to the first vehicle;

determining a second measure of impact severity in the system, the second measure of impact severity determined from information obtained from a source independent of the first vehicle;

weighting differently in the system the first measure of impact severity and the second measure of impact severity to develop a final measure of impact severity; and

storing the final measure of impact severity in the system for later use.

20. The method of claim 19, wherein said information comprises a change in velocity of said first vehicle.

21. The method of claim 19, further comprising selecting an algorithm to use in determining said first measure of impact severity based on a type of said event data recorder.

22. The method of claim 19, further comprising:

receiving input information related to the accident from a user of the system; and

determining if at least one inconsistency exists between the input information and the first measure of impact severity or the second measure of impact severity.

23. The method of claim 20, further comprising adjusting said change in velocity before determining said first measure of impact severity.

24. The method of claim 23, further comprising performing a simulation to generate a distribution of change in velocity calculations for said first vehicle using said adjusted change in velocity.

25. A computer-implemented method for analyzing a vehicle accident, comprising:

receiving information harvested from an event data recorder of a first vehicle in a system external to the first vehicle;

storing said information in a secure manner in said system;

accessing said information in said system;

determining a first measure of impact severity for said first vehicle in said system by modeling based at least in part on said information harvested from the event data recorder;

determining a second measure of impact severity in said system for said first vehicle without said information and using information obtained from an independent source from the event data recorder; and

storing the first measure of impact severity and the second measure of impact severity for later use.

26. The method of claim 25, wherein said information comprises a change in velocity of said first vehicle.

27. The method of claim 25, further comprising weighting the first measure of impact severity and the second measure of impact severity differently.
