Driver risk assessment system and method employing automated driver log
First Claim
1. A system for driving score generation, comprising:
- an interface configured to receive driving data comprising sensor data from one or more sensors on a vehicle; and
a processor configured to;
generate a drive event score for a driving trip of the vehicle based at least in part on the driving data;
normalize the drive event score based at least in part on one or more challenge factors; and
generate a driver score based at least in part on the normalized event score,wherein the driver score comprises a numerical representation used to rank a driver based at least in part on the one or more challenge factors and an effect of the one or more challenge factors on the driving trip.

Abstract
A Driver Risk Assessment System and Method Employing Automated Driver Log. 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, vehicle condition and/or tasking, roadway environmental conditions, 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 if the system concludes that a serious driving event has occurred. The system may respond to independent user requests by transferring select data to said user at a variety of locations and formats. Furthermore, by tracking driver identity and other environmental factors, the system may be configured to generate a driver score, a driver log, and a dispatch log. The driver score can be normalized by consideration of environmental factors related to the strenuousness of the driver'"'"'s driving or the driving challenges experienced by the driver during his or her driving trip.
