Motion Analysis of a Passenger in Reaction to Vehicle Sway Associated with Seating Posture

Abstract

A passenger seated on a 6-axis motion base has been exposed to vehicle sway that simulates lane-changing with the seat which changed the torso angle of the back rest and the position of the arm rest. The logistic regression result of the relationship between the subjective evaluation and the motion of the physical parts of the passenger measured with a motion capture system suggests that the angular velocity of skull is a major factor that influences subjective evaluation. In addition, it has been demonstrated that the armrest position influences the angular velocity of skull.
