ADAPTIVE VEHICLE CONTROL SYSTEM WITH DRIVING STYLE RECOGNITION BASED ON VEHICLE STOPPING
First Claim
1. A method for identifying whether a vehicle maneuver is a vehicle stopping maneuver, said method comprising:
- determining a vehicle speed and a vehicle longitudinal deceleration,determining whether an average of the vehicle longitudinal deceleration during a first time window is greater than a longitudinal deceleration threshold;
determining that the vehicle is in the vehicle stopping maneuver if the average of the vehicle longitudinal deceleration during the first time window is less than the longitudinal deceleration threshold; and
determining that the vehicle stopping maneuver has ended if the vehicle speed during a second time window is less than a speed threshold.

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 a vehicle longitudinal deceleration. The system determines whether an average of the vehicle longitudinal deceleration during a time window is greater than a longitudinal deceleration threshold and, if not, determines that the vehicle is in the stopping maneuver. The system then determines that the stopping maneuver has ended if the vehicle speed signal during another time window is less than a speed threshold. The style characterization processor can then classify the vehicle stopping maneuver using selected discriminant features.
