PROBLEM TO BE SOLVED: To effectively reduce a degree of damage applied to passengers due to collision, even when adequate physical safety measures have not been adopted.SOLUTION: When predicted that a collision will occur after time Tc, on the basis of relative position data with respect to an object obtained by a sensor 3 and a speed vector Vc, a vehicular posture range in which turning is possible within the collision prediction time Tc is obtained, and then the obtained vehicular posture range is divided into multiple small ranges to obtain collidable sites of a vehicle for each of the small ranges, before collision occurs with the object. Further, collision damage scores are obtained expressing a degree of collision damage for each site of the vehicle, and a vehicle site minimizing the collision damage score is selected, and then a vehicular posture is controlled by a drive unit 2 such that the selected vehicle site collides with the object.SELECTED DRAWING: Figure 2【課題】十分な物理的安全対策が施されていない場合でも、衝突により搭乗者が受ける被害の度合いを効果的に軽減する。【解決手段】対象物と衝突する前に、センサ３により得られた対象物との相対位置データおよび速度ベクトルＶc をもとに、時間Ｔc 後に衝突が発生すると予測した場合に、上記衝突予測時間Ｔc内に回動可能な車両の姿勢の範囲を求め、この姿勢の範囲を複数の小範囲に分割してこれらの小範囲ごとに衝突させることが可能な車両の部位を求める。そして、この車両の部位ごとに衝突被害の度合いを表す衝突被害スコアを求めて、この衝突被害スコアが最少となる車両の部位を選択し、この選択された車両の部位が対象物と衝突するように、駆動装置２により車両の姿勢を制御する。【選択図】図２
