Development of Evaluating Methods for Passenger’s Motion Sickness in Real Driving Environment

Abstract

With the commercialization of autonomous driving technology and diversification of how passengers spend their time, it is concerned that a mismatch between somatosensory and visual information induces motion sickness. However, no effective quantitative method using physiological indices in driving conditions of a vehicle has been found out. The objective of this study is to develop a robust method for quantitative evaluation in real driving environment. As a result of inducing motion sickness of a back passenger by driving a vehicle on a test course, changes of forehead humidity, which reflects the amount of sweating, increased significantly. The result indicates forehead humidity is an effective index for quantifying motion sickness in real driving environment.
