Evaluation method for motion sickness and evaluation device for motion sickness

摘要

The present invention provides a method for evaluating motion sickness and a device for evaluating motion sickness that can prevent deterioration of evaluation accuracy and can evaluate motion sickness with high accuracy. SOLUTION: Translational acceleration and angular velocity of a moving vehicle are based on outputs of three two-axis acceleration sensors 11 arranged such that the directions of at least one axis are different from each other, and a three-axis angular velocity sensor 12. Are measured, and based on the measured translational acceleration and angular velocity, an discomfort index that represents the discomfort of the occupant is determined. The discomfort indicator is, for example, one of a frequency component of heart rate variability of an occupant, a heart rate, and an index obtained from a heart rate interval. The discomfort index is preferably determined based on the peak frequency and standard deviation of the measured translational acceleration or its rate of change, and a linear expression having the peak frequency and standard deviation of the measured angular velocity as variables.
