A Fuzzy Geometrical Evaluation Method for Motorcycle Driver's Posture

This paper presents a method for evaluating the comfort of driving posture on motorcycle.The method applies theory of reverse motivation for calculating the key angles of drivers on motorcycle and fuzzy logic for evaluating the comfort of the drivers. In the environment of VC++6.0,we draw the model of the driver and present the routine for fuzzy evaluation using the method of fuzzy logic.
