Abstract

A method of evaluating a driving skill executed by a computer includes a skill evaluation step of evaluating a driver's driving skill based on a detection value of a vehicle state, a component separating step of separating the detection value of the vehicle state into a driver's operation component reflecting a driver's motion and a non-driver's operation component without reflecting the driver's motion, and a skill evaluation modifying step of correcting or abandoning evaluation of the driving skill based on at least one of an amount of the driver's operation component and an amount of the non-driver's operation component.
