Abstract
A driver handling skill recognition system and related algorithm that identifies a driver skill level. The system includes a steering wheel angle processor responsive to a steering wheel angle signal that provides normalized DFT coefficients. The system also includes at least one feed-forward artificial neural network (FF-ANN) responsive to the normalized DFT coefficients, where the FF-ANN provides an output signal indicative of the driver skill level. In one embodiment, the system includes a plurality of FF-ANNs one for each of a plurality of different vehicle maneuvers. The system includes a maneuver identifier that identifies a vehicle maneuver. The system selects the output from one of the FF-ANNs depending on the identified maneuver. In an alternate embodiment, the system can include a single FF-ANN designed for a plurality of vehicle maneuvers.
