ADAPTIVE VEHICLE CONTROL SYSTEM WITH DRIVING STYLE RECOGNITION BASED ON HEADWAY DISTANCE
First Claim
1. A system for classifying a drivers driving style of a subject 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 maneuvers of the vehicle relating to a headway distance between the subject vehicle and a preceding vehicle, said maneuver identification processor determines a range and range rate between the subject vehicle and the preceding vehicle, and providing maneuver identifier signals including the range rate; and
a style characterization processor responsive to the maneuver identifier signals, said style characterization processor classifying the driving style based on the signals and providing driving style classification signals that identify the type of driver driving the subject vehicle.

Abstract
An adaptive vehicle control system that classifies a drivers driving style based on vehicle headway control. The system reads sensor signals to identify the range and range rate between a subject vehicle and a preceding vehicle, where the range rate is close to zero if the distance between the subject vehicle and the preceding vehicle is relatively steady, the range rate is negative when the subject vehicle is closing in on the preceding vehicle and the range rate is positive when the subject vehicle is falling behind the preceding vehicle. The range rate, the subject vehicle speed and other signals are used to classify the drivers driving style based on how fast the subject vehicle closes in on the preceding vehicle or falls behind, and the following distance between the subject vehicle and the preceding vehicle. The system can then classify the headway-control maneuver using selected discriminant features.
