Abstract

A Method and System for Tuning the Effect of Vehicle Characteristics on Risk Prediction is disclosed. The system many incorporate many of those driver risk assessment system features previously disclosed by Assignee'"'"'s Prior Applications. The present system provides a major functional distinction from those prior systems by adding the feature of real-time tuning of the risk assessment/prediction/analysis system in response to ongoing changes in vehicle motion characteristics. Specifically, system monitors the vehicle center of gravity for changes on a real-time basis, and then adjusts the risk prediction/assessment/analysis system responsively. The system executes an initialization feature that implements an initial, or series of initial vehicular motion profiles at the commencement of either a driving trip of the system being powered up. A catalog or index of “standardized” motion profiles are accessible for initial comparison to actual vehicle motion characteristics in order to streamline the tuning of the driver risk analysis system. The system determines if and when an offset in Center of Gravity (i.e. from where initialized) has occurred, after which the system responsively tunes the driver risk assessment/prediction/analysis/reporting system.

Claims

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

a spatial motion sensor coupled to a vehicle that provides spatial motion data;

a processor configured to;

compare the spatial motion data of the vehicle to a historical motion profile of the vehicle stored in a data repository;

determine whether the spatial motion data of the vehicle is consistent with the historical motion profile of the vehicle, wherein the vehicle has particular spatial motion characteristics that are stored in the historical motion profile for that particular vehicle;

in the event that a first predetermined amount of inconsistency is detected in the spatial motion data in comparison to the historical motion profile, provide a first alert indicating historical inconsistency;

determine whether the spatial motion data is inconsistent by a second predetermined amount that indicates the spatial motion sensor has been moved to a different vehicle, wherein the second predetermined amount indicates a more drastic change in the spatial motion characteristics;

in the event that the spatial motion data of the vehicle indicates that the spatial motion sensor has been moved to the different vehicle, provide a second alert that the spatial motion sensor has changed to the different vehicle.

2. A system as in claim 1, wherein the first alert is provided to an evaluation server.

3. A system as in claim 1, wherein the second alert is provided to an evaluation server.

4. A system as in claim 1, wherein the first predetermined amount of inconsistency indicates that the event capture device has changed.

5. A system as in claim 1, wherein first predetermined amount of inconsistency indicates that the vehicle has wear/maintenance issues.

6. A system as in claim 1, wherein first predetermined amount of inconsistency indicates that the vehicle is improperly loaded.

7. A system as in claim 1, wherein first predetermined amount of inconsistency indicates that the vehicle is being used for improper purposes.

8. A system as in claim 1, wherein the processor is further configured to in the event the spatial motion data is consistent, continue monitoring the spatial motion.

9. A system as in claim 1, wherein the spatial motion data further comprises a center of gravity offset.

10. A system as in claim 1, wherein the processor is further configured to determine whether a center of gravity offset is within a vehicle type/class profile of the vehicle.

11. A system as in claim 1, wherein the processor is further configured to detect a driving event based at least in part on a trigger threshold.

12. A system as in claim 1, wherein the processor is further configured to store driving event data in the event a driving event is detected.

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

comparing spatial motion data of the vehicle to a historical motion profile of the vehicle stored in data repository;

determining, using a processor, whether the spatial motion data of the vehicle is consistent with the historical motion profile of the vehicle, wherein the vehicle has particular spatial motion characteristics that are stored in the historical motion profile for that particular vehicle;

in the event that a first predetermined amount of inconsistency is detected in the spatial motion data in comparison to the historical motion profile, providing a first alert indicating historical inconsistency;

determining whether the spatial motion data is inconsistent by a second predetermined amount that indicates the spatial motion sensor has been moved to a different vehicle, wherein the second predetermined amount indicates a more drastic change in the spatial motion characteristics;

in the event that the spatial motion data of the vehicle indicates that the spatial motion sensor has been moved to the different vehicle, provide a second alert that the spatial motion sensor has changed to the different vehicle.

14. A method as in claim 13, wherein the first alert is provided to an evaluation server.

15. A method as in claim 13, wherein the second alert is provided to an evaluation server.

16. A method as in claim 13, wherein the first predetermined amount of inconsistency indicates that the event capture device has changed.

17. 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:

comparing spatial motion data of the vehicle to a historical motion profile of the vehicle stored in data repository;

determining whether the spatial motion data of the vehicle is consistent with the historical motion profile of the vehicle, wherein the vehicle has particular spatial motion characteristics and that are stored in the historical motion profile for that particular vehicle;

in the event that a first predetermined amount of inconsistency is detected in the spatial motion data in comparison to the historical motion profile, providing a first alert indicating historical inconsistency;

determining whether the spatial motion data is inconsistent by a second predetermined amount that indicates the spatial motion sensor has been moved to a different vehicle, wherein the second predetermined amount indicates a more drastic change in the spatial motion characteristics;

in the event that the spatial motion data of the vehicle indicates that the spatial motion sensor has been moved to the different vehicle, provide a second alert that the spatial motion sensor has changed to the different vehicle.
