Ride Comfort Control System Considering Physiological, Psychological, and Psychological Characteristics: Experimental Study of LIR

Ultracompact mobility refers to vehicles that are intended for near-distance travel for one to two passengers. This mobility is compact and easy to turn around, so it can enter narrow roads and poor roads that are not paved. In such a road surface environment, it is susceptible to the influence of vibration caused by steps and the unevenness of the road surface, and deterioration of the ride comfort of the vehicle is expected even at low speed. The authors analyzed an organoleptic evaluation and biological information to improve the ride comfort based on a proposed control method. In this paper, the stress state of the occupant received by the vertical vibration is clarified from the cerebral blood flow, which is used as an indicator of the activity of the central nervous system.
