Abstract

A system for evaluating risk in driving comprises a processor and a memory. The processor is configured to determine whether a spacial motion data does not fall within the vehicle profile and, in the event that the spacial motion data does not fall within the vehicle profile, to change class/type assignment associated with the vehicle and to modify a trigger threshold associated with an event detector that monitors the spacial motion data. The memory is coupled to the processor and is configured to provide the processor with instructions.

Claims

1. A system for evaluating risk in driving, comprising:

a processor configured to;

determine whether a spacial motion data falls within a vehicle profile of a vehicle; and

in the event that the spacial motion data does not fall within the vehicle profile;

change class/type assignment associated with the vehicle; and

modify a trigger threshold associated with an event detector that monitors the spacial motion data; and

a memory coupled to the processor and configured to provide the processor with instructions.

2. The system of claim 1, wherein the processor is further configured to determine whether a spacial motion data is consistent with a historical profile.

3. The system of claim 2, wherein determining whether the spacial motion data is inconsistent with the historical profile more than a predetermined amount.

4. The system of claim 2, wherein in the event that the spacial motion data is not consistent with the historical profile, then the processor is further configured to provide an alert.

5. The system of claim 4, wherein the alert indicates one or more of the following:

an equipment change, a maintenance issue, or an improper vehicle loading.

6. The system of claim 1, wherein the spacial motion data comprises a center of gravity offset.

7. The system of claim 1, wherein the processor is further configured to adjust a filtration parameter associated with a raw data filter.

8. A method for evaluating risk in driving, comprising:

determining, using a processor, whether a spacial motion data falls within a vehicle profile of a vehicle; and

in the event that the spacial motion data does not fall within the vehicle profile;

changing class/type assignment associated with the vehicle; and

modifying a trigger threshold associated with an event detector that monitors the spacial motion data.

9. The method of claim 8, further comprising determining whether a spacial motion data is consistent with a historical profile.

10. The method of claim 9, wherein determining whether the spacial motion data is inconsistent with the historical profile more than a predetermined amount.

11. The method of claim 9, wherein in the event that the spacial motion data is not consistent with the historical profile, then providing an alert.

12. The method of claim 11, wherein the alert indicates one or more of the following:

an equipment change, a maintenance issue, or an improper vehicle loading.

13. The method of claim 8, wherein the spacial motion data comprises a center of gravity offset.

14. The method of claim 8, further comprising adjusting a filtration parameter associated with a raw data filter.

15. A computer program product for evaluating risk in driving, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

determining whether a spacial motion data falls within a vehicle profile of a vehicle; and

in the event that the spacial motion data does not fall within the vehicle profile;

changing class/type assignment associated with the vehicle; and

modifying a trigger threshold associated with an event detector that monitors the spacial motion data.

16. The computer program product recited in claim 15, further comprising determining whether a spacial motion data is consistent with a historical profile.

17. The computer program product recited in claim 16, wherein determining whether the spacial motion data is inconsistent with the historical profile more than a predetermined amount.

18. The computer program product recited in claim 16, wherein in the event that the spacial motion data is not consistent with the historical profile, then providing an alert.

19. The computer program product recited in claim 18, wherein the alert indicates one or more of the following:

an equipment change, a maintenance issue, or an improper vehicle loading.

20. The computer program product recited in claim 15, wherein the spacial motion data comprises a center of gravity offset.

21. The computer program product recited in claim 15, further comprising adjusting a filtration parameter associated with a raw data filter.
