  • Publication number: 20100209891
    Abstract: A skill characterization processor classifies driver skill based stop and go maneuvers. A maneuver identification processor determines whether the vehicle is in a braking maneuver, and the system determines the vehicle longitudinal deceleration, the brake pedal position and the brake pedal rate from the brake pedal position. The skill characterization processor then classifies the driver's driving skill based on the brake pedal rate, the brake pedal position and the vehicle longitudinal deceleration generally under normal driving conditions. In one embodiment, the processor classifies driver skill by performing frequency analysis on the brake pedal rate using a discrete Fourier transform to find a frequency component of the brake pedal rate to obtain a power spectrum density.

  • Publication number: 20100152950
    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.

  • Publication number: 20100152951
    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.

  • Publication number: 20100087987
    Abstract: A vehicle includes vehicle systems each having driver-selectable vehicle system settings (VSS), and a control system for statistically modeling the VSS to determine an identity of a driver. The control system automatically controls a setting of at least one of the vehicle systems using or based on the identity. The control system statistically models the VSS for the driver over time to produce a historical driver profile (HDP) for the driver, and can automatically update the HDP when said driver manually changes any one of the VSS. An optional driver identification device can verify the identity. A method for controlling a predetermined onboard system of a vehicle includes collecting a set of VSS for a plurality of onboard systems, processing the VSS through a statistical modeling algorithm to determine an identity of a driver of the vehicle, and automatically controlling a predetermined onboard system using the identity of the driver.

  • Publication number: 20100023180
    Abstract: An adaptive vehicle control system that classifies a driver's driving style based on lane-change maneuvers. A maneuver identification classification process reads sensor signals for vehicle speed, vehicle yaw rate and vehicle heading angle. The process determines if the vehicle is turning based on whether the yaw rate signal is greater than a yaw rate threshold and whether the heading angle is greater than a heading angle threshold. The process then determines whether the maneuver is an ordinary curve-handling maneuver or a lane-change maneuver by determining whether the yaw rate signal is greater than another yaw rate threshold, the difference between the heading angle and an initial heading angle is greater than another heading angle threshold and the lateral deviation is greater than a lateral deviation threshold. If the curve-handling maneuver is a lane-change maneuver, a maneuver identifier signal is provided to a style characterization processor.

  • Publication number: 20100023181
    Abstract: An adaptive vehicle control system that classifies a driver's driving style based on vehicle passing maneuvers. A process determines whether the vehicle has started a lane change from a first lane to a second lane as a first phase of the passing maneuver. If so, the process determines whether the lane change to the second lane has been completed as a second phase of the passing maneuver. If the lane change to the second lane has been completed, the process determines whether there has been a lane change back to the first lane to complete the passing maneuver as a third phase of the passing maneuver. Further, the process determines whether a time threshold has been exceeded after the passing maneuver is in a second phase, but no lane change back to the first lane has occurred.

  • Publication number: 20100023216
    Abstract: An adaptive vehicle control system that classifies a driver's driving style based on left/right-turn maneuvers. A process determines if the vehicle has started a turn if the yaw rate is greater than a first yaw rate threshold, and determines a vehicle heading angle based on the yaw rate and a sampling time if the vehicle has started a turn. The process then determines whether the vehicle maneuver has been completed by determining if the yaw rate is less than a second yaw rate threshold. The process then determines that the completed maneuver was a left/right-turn maneuver if the yaw rate is less than a third yaw rate threshold over the sampling time and the vehicle heading angle is within a heading angle range for a time period less than a predetermined time threshold. In one non-limiting embodiment, the heading angle range is between 75° and 105°.

  • Publication number: 20100023196
    Abstract: An adaptive vehicle control system that classifies a drivers driving style based on vehicle launching maneuvers. A process determines whether the vehicle speed signal during a predetermined time window is greater than a speed threshold, whether the vehicle speed signal before the time window is less than the speed threshold and whether the average of the vehicle longitudinal acceleration during the time window is greater than a first longitudinal acceleration threshold and, if so, determines if the vehicle is in a vehicle launching maneuver. The process then determines that the vehicle launching maneuver has ended if the average of the vehicle longitudinal acceleration during a second time window is less than the longitudinal acceleration threshold. The style characterization processor can then classify the vehicle launching maneuver using selected discriminant features.
