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 method for evaluating risk in driving, comprising:

initializing a spacial motion detecting event capture device associated with a vehicle, said initialization comprising tuning said device responsive to preset vehicle type/class data;

monitoring vehicle spacial motion with said spacial motion detecting event capture device;

capturing driving event data at one or more event capture devices coupled with said vehicle;

analyzing the driving event data with at least one event detector device to calculate a driving event score, said score responsive to said spacial motion monitoring; and

combining a plurality of driving event scores in a local data repository associated with said vehicle.
