Abstract

Aiming development of mechanical system which allows intervention of human factors without conflicts, ambiguous characteristics of vehicle drivers in path selection is discussed. The hypothesis of this study is that in order to achieve sufficient robustness constrained from driving environment, drivers intentionally control the distribution of their path on the road by controlling their sensory-motor system. Computer simulation using the preview driver model and behavioral experiment is conducted, and the hypothesis is discussed based on these experimental results. The simulation result shows that robustness can be regulated by the distribution of lateral deviations, whereas the result of behavioral experiment shows that lateral distribution is significantly constrained from road width. This suggests that driver balances between robustness and constraints by controlling distribution of lateral deviation.
