To accurately calculate a behavior of an occupant seated on a vehicular seat.SOLUTION: The human body behavior program uses a human body behavior model which is divided into an upper part including a head and a chest, a middle part including a pelvis, and a lower part including a lower half of body which is a lower part of the pelvis, and which comprises a joint 1 between the middle part and lower part and a joint 2 between the upper part and the middle part, for calculating a joint torque of the joint 1 for preventing posture loss, from a joint angle of the joint 1, then, for calculating a joint torque of the joint 2 for inverting a head against the acceleration applied to a vehicle, according to the acceleration of the head, for calculating a behavior of an occupant including the joint angle of the joint 1 and the joint angle of the joint 2.SELECTED DRAWING: Figure 1
【課題】車両のシートに着座した乗員の挙動を精度良く計算することができるようにする。【解決手段】頭部及び胸部を含む上部、骨盤を含む中部、及び骨盤より下の下半身を含む下部に分割され、中部及び下部の間の関節1と、上部及び中部の間の関節2とを有する人体挙動モデルを用いて、姿勢の崩れを防ぐための関節1の関節トルクを、関節1の関節角から演算し、車両に印加される加速度に対抗して頭部を倒立させるための関節2の関節トルクを、頭部の加速度に応じて演算することにより、関節1の関節角と、関節2の関節角とを含む乗員の挙動を計算する。【選択図】図1
