Recently, an improvement of ride comfort is essential for vehicle designs to add commodity value. A technique to well estimate the ride comfort for vehicle passengers is strongly required from the above viewpoint. This paper investigates the modeling of a passenger with consideration of a postural control system of human body. Firstly, a passenger model on a rigid seat is constructed by multi-body approach, where only the passive property is taken into account. Secondly, the postural control system of human body is introduced into the multi-body model. The frequency range of interest is up to 3Hz, and the input vibration direction is in lateral direction.
