Human Factors in the Steering System of Two Wheeled Vehicles

Abstract

This study analyzes the role of human factors in the steering system of two-wheeled vehicles, using equivalent mechanical elements as the first step toward systems analysis of the man/vehicle relationship. This steering system, including human factor, has approximately one torsional degree of freedom. These factors can be obtained by the frequency response of the steering bench model with rider. First, the reproducibility and linearity of human factors are checked. Then, the human factor values are shown, changing accordingly as the rider's handle grip and press forces vary. Finally, the equation for two-wheeled vehicle motion is derived, and the result of these calculations makes it clear that human factors play a major role in the behavior of two wheeled vehicles.
