Ride Comfort Control System of Active Seat Suspension by Using Psychological Measurement

(Prediction of Subjective Evaluation by Multiple Biological Signal Processing)

Abstract

The authors have proposed to mount a small active seat suspension on the seat as a way to improve ride comfort. In this paper, we investigated quantitative and objective method for evaluation of ride comfort. In addition, participants evaluated the feel of ride comfort in the experiments by a visual analog scale (VAS), and the results were digitized to VAS values which were able to quantitively evaluated the ride comfort. Moreover, the relationship between participants’ biological information and their VAS values was modeled by using multiple regression analysis, and an estimation function of the occupants' ride comfort was established from the model. Therefore, the possibility of objective evaluation for subjective ride comfort was investigated using the model.
