Analysis on the effects of high frequency body vibrations for vehicle maneuver feeling

Abstract

Influence of body stiffness on vehicle maneuverability and handling characteristics has been open problem for decades. This paper focuses on the influence of the high frequency body vibration on human motion sensitivity, and clarifies that the vibration reduction in the 20 Hz band shortens the time to recognize the lateral motion during the minute lane change. Furthermore, we derive sensory quantity of the lateral motion from skin shear displacement on the contact point with sheet back, and clarify the mechanism that "vibration reduction in the 20 Hz band reduces the noise of the sensory quantity of lateral motion and shortens the recognition time of the lateral motion". This shows that "vehicle body vibration characteristics in the 20 Hz band effect vehicle maneuver feeling".
