First Claim
Patent Images
1. A method for determining a driver'"'"'s driving skill of a vehicle, said method comprising:
- reading a vehicle speed signal and a vehicle yaw rate signal from vehicle sensors;
determining that the vehicle has started a turn if the yaw rate signal is greater than a first yaw rate threshold;
determining a vehicle heading angle based on the yaw rate signal and a sampling time if the vehicle has started a turn;
determining that the vehicle maneuver has been completed if the yaw rate signal is less than a second yaw rate threshold;
determining that the completed maneuver was a left/right-turn maneuver if the vehicle yaw rate signal is less than a third yaw rate threshold during the maneuver, the vehicle heading angle at the end of the maneuver is within a heading angle range and the time duration of the maneuver is less than a predetermined time threshold; and
classifying the driver'"'"'s driving skill using information obtained from the left/right-turn maneuver.

Abstract
A system that classifies driver driving skill based on left/right turning maneuvers. The system reads sensor signals for vehicle speed and vehicle yaw rate. The system determining that the vehicle has made a left/right-turn maneuver using the vehicle speed signal and the yaw-rate signal and then classifies the driver'"'"'s driving skill using selected discriminant features obtained or derived from the left/right-turn maneuver.
