Abstract
A system for classifying a driver'"'"'s driving skill of a vehicle based on behavioral diagnosis. A plurality of vehicle sensors providing vehicle measurement signals. A maneuver qualification and identification processor qualifies and identifies characteristic maneuver identifying signals and a maneuver index and parameter processor creates a maneuver index and identifies relevant vehicle parameters. A path reconstruction processor reproduces an intended vehicle path for each characteristic maneuver identified by the maneuver characteristic processor. A maneuver model processor models the characteristic maneuvers and a driving skill diagnosis processor provides driving skill signals based on the maneuver model and driver input data. The driving skill diagnosis processor converts the maneuver model signals and the driver command input signal to the frequency domain to provide frequency content discrepancy analysis.
