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:

an interface to

receive a spacial motion data; and

a processor to;

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

in the event that the spacial motion data does not fall within the vehicle profile, modify trigger threshold levels for event detection.

2. A system as in claim 1, wherein the spacial motion comprises a motion in an x axis.

3. A system as in claim 1, wherein the spacial motion comprises a motion in a y axis.

4. A system as in claim 1, wherein the spacial motion comprises a motion in a z axis.

5. A system as in claim 1, wherein the spacial motion comprises a pitch motion.

6. A system as in claim 1, wherein the spacial motion comprises a roll motion.

7. A system as in claim 1, wherein the spacial motion comprises a yaw motion.

8. A system as in claim 1, wherein the spacial motion comprises an acceleration.

9. A system as in claim 1, wherein the vehicle profile comprises a range of motion.

10. A system as in claim 1, wherein the vehicle profile comprises a center of gravity location.

11. A system as in claim 1, wherein the vehicle profile comprises a rigidity of a ride.

12. A system as in claim 1, wherein the vehicle profile comprises a range of motion.

13. A system as in claim 1, wherein the vehicle profile comprises a standardized motion profile.

14. A system as in claim 1, wherein the vehicle profile comprises a historical profile.

15. A system as in claim 1, wherein the vehicle profile comprises a changed profile.

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

receiving a spacial motion data;

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

in the event that the spacial motion data does not fall within the vehicle profile, modifying trigger threshold levels for event detection.

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:

receiving a spacial motion data;

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