Vibration Stress

Active seat suspension has been proposed to improve ride comfort for ultra-compact mobility. Regarding the ride comfort of passengers due to vertical vibration, the authors have confirmed from biometry measurements that reduction of the vibration acceleration does not always produce the best ride comfort for passengers. Therefore, heart rate variability that can quantitatively reflect stress is measured in real time, and a control method was proposed that feeds back to active suspension and confirms its effectiveness by fundamental verification. In this paper, we will confirm the influence of the vibration stress on the psychological state of the occupant by the masking method.

Low Weight

In the current automobile industry, the demand for ultra-compact vehicles as a means of transportation for elderly people and other travelers, has been increasing. The effect of vibration on the ride comfort of these vehicles is significant because of their small size and low weight. The vibration will increase the discomfort perceived by persons in the vehicle. Therefore, it is necessary to develop a vibration control system for safe and comfortable driving. To improve ride comfort, this research group proposed an active seat suspension using a voice coil motor at the seat section of the vehicle. In this study, the influence of jerk on the psychological state, which was obtained from bioinstrumentation, was investigated.
