Driver Risk Assessment System and Method Having Calibrating Automatic Event Scoring
First Claim
1. A system for reducing risk in driving, comprising:
- at least one event capture device associated with a vehicle, said event capture device or devices detecting data related to the physical condition of said vehicle;
at least one event detector device coupled with the vehicle and configured to communicate with said event capture device or devices and to predict, responsive to analysis of the group of data captured by said event capture devices, whether or not data captured by said event capture devices represents a driving event, and assigning a unique risk identifier selected from a group of risk identities to said driving event;
an event scoring module attached to or otherwise associated to communicate with said event detector for generating an event score based upon the assigned said risk identifier data from said event capture device or devices and applying risk confidence data related to the specific risk; and
an event data management module attached to or otherwise associated to communicate with said event detector for uploading data from said event capture devices to a remote computing device, with said uploading being responsive to said event score.

Abstract
The system and method provides robust and reliable event scoring and reporting, while also optimizing data transmission bandwidth. The system includes onboard vehicular driving event detectors that record data related to detected driving events, selectively store or transfer data related to said detected driving events. If elected, the onboard vehicular system will score a detected driving event, compare the local score to historical values previously stored within the onboard system, and upload selective data or data types to a remote server or user if the system concludes that a serious driving event has occurred. Importantly, the onboard event scoring system, if enabled, will continuously evolve and improve in its reliability by being periodically re-calibrated the ongoing reliability results of manual human review of automated predictive event reports. The system may further respond to independent user requests by transferring select data to said user at a variety of locations and formats.

14. A method for evaluating risk in driving, comprising the steps of:
-
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 assign a predicted driving event identifier selected from a pre-determined group of driving event identifiers; assigning an event score to said predicted driving event identifier, said event score being either the result of actual human review of said driving event data associated with said predicted driving event identifier, or the historical confidence that prior human review of driving event data leading to the same predicted driving event identifier was confirmed; and selectively uploading all or part of said captured data to a remote computing device, said selective uploading being responsive to said assigned event score. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method for reducing risk in driving, comprising:
- obtaining a plurality of driving event data for the individual driver, said event data comprising selectively uploadable video or audio data and regularly uploaded velocity, acceleration, vehicle spatial orientation and heading, vehicle metadata and vehicle location data, the driving event data obtained from a data storage area comprising a plurality of captured driving event data for a plurality of drivers;
analyzing the plurality of regularly uploadable driving event data;
analyzing demographic data for the individual driver, said demographic data obtained from a data storage area comprising a plurality of driver records, said records comprising demographic data; and
scoring the individual driver based on the analysis of the plurality of driving event data and the analysis of the demographic data; and
uploading relevant portions of said selectively uploadable video and audio data to a remote computing device responsive to a two-stage analysis of said driving event data, said first stage being the numerical analysis of the driving event data in order to generate a predicted event identifier selected from a group of potential event identities, and the second stage being the assignment of a confidence score to the generated predicted event identifier, with said confidence score being responsive to intermittent human review of predicted driving events.
- obtaining a plurality of driving event data for the individual driver, said event data comprising selectively uploadable video or audio data and regularly uploaded velocity, acceleration, vehicle spatial orientation and heading, vehicle metadata and vehicle location data, the driving event data obtained from a data storage area comprising a plurality of captured driving event data for a plurality of drivers;
