US 7,389,178 B2 · System and method for vehicle driver behavior analysis and evaluation

Abstract

A system and method for analyzing and evaluating the performance and attitude of a motor vehicle driver. A raw data stream from a set of vehicle sensors is filtered to eliminate extraneous noise, and then parsed to convert the stream into a string of driving event primitives. The string of driving events is then processed by a pattern-recognition system to derive a sequence of higher-level driving maneuvers. Driving maneuvers include such familiar procedures as lane changing, passing, and turn and brake. Driving events and maneuvers are quantified by parameters developed from the sensor data. The parameters and timing of the maneuvers can be analyzed to determine skill and attitude factors for evaluating the driver's abilities and safety ratings. The rendering of the data into common driving-related concepts allows more accurate and meaningful analysis and evaluation than is possible with ordinary statistical threshold-based analysis.

Dependent claims

A system for analyzing and evaluating the performance and behavior of a driver of a vehicle, the system comprising:

(a) a vehicle sensor utility operative to monitor the state of the vehicle and to output a raw data stream corresponding thereto;
(b) a driving event handler operative to receive the raw data stream, detect from said raw data stream a plurality of distinctive patterns each associated with a corresponding driving event representation and to output a driving event string containing said driving event representations and their corresponding values;
and
(c) a maneuver detector operative to receive said driving event string, compare a sequence of said driving event representations comprised in the driving event string with patterns of driving maneuvers comprised in a database, to enable recognizing patterns of driving maneuvers in said driving event string and to construct and output a driving maneuver representation corresponding thereto, said driving maneuver representation containing a representation of at least one driving maneuver.
