Improvement of Vehicle Dynamics Based on Human Sensitivity (First Report) - Development of Human Sensitivity Evaluation System -

An understanding of human sensitivity is an important factor in enhancing vehicle dynamics. The purpose of this study was to evaluate human sensitivity to vehicle dynamics, especially visual and motion sensitivity. The first step of this study involved the development of a human sensitivity evaluation system composed of a highly responsive six-degree-of-freedom motion device and a visual device with high spatial frequency resolution. This system is able to apply sensory and visual information to a test subject corresponding to that experienced during driving. Perceptional characteristics with regard to single motions were evaluated using this system.
