618 Quantifycation of vibration ride comfort by physiological index

Abstract

We quantified the sense of ride comfort Mr. Mitsumoto has, who has been a car journalist for a long time, with a new evaluating method called sensitive response MAP using the physiological index (Aortic Pulse Wave: hereinafter referred to as APW). This method is corresponding to the subjective rating well therefore it is suggested that this method can catch a psychological change. Furthermore it is shown that this method synchronizes with the result of the ride comfort by using response acceleration. Thus it is suggested that sensitive response MAP can be applied to the evaluation of ride comfort.
