Abstract
Various vehicles are produced according to the development of the industrial technology. The driver will take a different driving posture for vehicles of these various vehicles. Moreover, not only the driving posture but also driver itself diversifies because of increases of the senior citizen and female drivers. The combinations of the driving posture and drives become vast number. In the future, the system that can simulate various driving posture and physical characteristic to develop the vehicle is necessary. Then, the study develops postural evaluation system based on biomechanics simulation. In this paper, the introduction of the outline of the postural evaluation system and the consideration of the posture evaluation result are done. From the results of numerical simulation, Muscle activity could be obtained according to running situation.
