초록 As an approach to evaluate human comfort during driving conditions, an objective riding comfort evaluation measure is proposed. The related feeling due to vehicle motion associated with low-frequency roll and pitch motions is called ‘hold feeling’. We consider the degree of interference and the sense of unity between each part of a seated human body. The present approach is based on the dynamic pressure distribution measurements for a seated subject on a seesaw-type, roll motion simulator. According to the present experimental results for two selected commercial seats, a high-end seat( seat A) and a popular seat(seat B), the consistently higher temporal variation of segmental pressure ratio at the hip region is identified with seat B, which may negatively affect the level of comfort associated with higher SPD(seat pressure distribution) values. The proposed hold feeling evaluation method may be a good candidate as an objective measure to evaluate seat comfort in low-frequency, dynamic environments.
