Adaptive vehicle control system with integrated maneuver-based driving style recognition
First Claim
1. A system for classifying a driver'"'"'s driving style of a vehicle, said system comprising:
- a plurality of vehicle sensors providing sensor measurement signals;
a maneuver identification processor responsive to the sensor signals from the plurality of vehicle sensors, said maneuver identification processor identifying different characteristic maneuvers of the vehicle and providing maneuver identifier signals identifying the characteristic maneuvers; and
a style characterization processor responsive to the maneuver identifier signals and the sensor measurement signals, said style characterization processor including separate classifiers for each different type of maneuver, said classifiers being selected based on the maneuver identifier signal to classify driving style using sensor signals corresponding to a particular maneuver, each classifier providing a driver style classification signal that identifies the type of driver driving the vehicle for the particular maneuver, said style characterization processor further including a first combiner that receives and combines the style classification signals from each of the selected classifiers and provides a combined style classification signal for a single one of several different maneuvers.

Abstract
A vehicle control system that classifies a driver'"'"'s driving style based on characteristic maneuvers. The system includes a plurality of vehicle sensors that detect various vehicle parameters. A maneuver identification processor receives the sensor signals to identify a characteristic maneuver of the vehicle and provides a maneuver identifier signal of the maneuver. A style characterization processor receives the maneuver identifier signals, sensor signals from the vehicle sensors and the traffic and road condition signals, and classifies driving style based on the signals to classify the style of the driver driving the vehicle. The classification of the driver style can be provided for a level-1 combination that combines the classification results from different maneuver type classifiers for a single maneuver, a level-2 combination that combines the classification results from multiple maneuvers that are of the same type and a level-3 combination that combines the classification results from different types of characteristic maneuvers.
