ADAPTIVE VEHICLE CONTROL SYSTEM WITH DRIVING STYLE RECOGNITION BASED ON VEHICLE ACCELERATING AND DECELERATING
First Claim
1. A method for identifying whether a vehicle maneuver is a vehicle accelerating and decelerating maneuver, said method comprising:
- determining a speed of the vehicle;
determining whether the vehicle is driving in a straight line;
determining whether the vehicle is driving on a curve;
determining whether the vehicle speed is greater than a vehicle speed threshold during a first time window;
determining that the vehicle is in the vehicle accelerating and decelerating maneuver if the vehicle is driving in a straight line or driving on a curve and the vehicle speed is less than the speed threshold during the first time window; and
determining that the vehicle accelerating and decelerating maneuver has ended if the vehicle is not driving in a straight line, is not driving on a curve or the vehicle speed is less than the vehicle speed threshold during a second time window.

Abstract
An adaptive vehicle control system that classifies a driver'"'"'s driving style based on vehicle stopping maneuvers. The system reads sensor signals to provide a vehicle speed and determines whether the vehicle is currently in straight line driving or curve driving. If the vehicle is in straight line or curve driving and the vehicle speed is less than a speed threshold, the system determines that the vehicle is in an accelerating or decelerating maneuver. The system then determines that the accelerating and decelerating maneuver has ended if the vehicle is not in straight line or curve driving or the vehicle speed signal is less than the speed threshold. The system can then classify the vehicle accelerating and decelerating maneuver using select discriminate features.
