To provide a front bumper unit of a vehicle which prevents deterioration of impact absorption performance during a frontal collision or a pedestrian collision while inhibiting deterioration of cooling performance of a radiator caused by a bumper beam and impact absorption materials.SOLUTION: A front bumper unit of a vehicle is constituted so as to include: a bumper beam (32) disposed in front of a radiator; impact absorption members (39) which are disposed at a front side of the bumper beam in a manner such that the impact absorption members can move in a lateral direction; a bumper fascia (50) which covers the bumper beam and the impact absorption members from the front side of the vehicle; impact absorption member moving means (60) which move the impact absorption members; collision detection means (70L, 70R) which detect a collision of a collided body (80) with the bumper fascia; and controlling means (90) which can control the impact absorption member moving means on the basis of information from the collision detection means. The controlling means determines a collision position of the collided body on the basis of the information from the collision detection means and moves the impact absorption members to positions corresponding to the collision position according to the collision position.SELECTED DRAWING: Figure 5
【課題】バンパビームや衝撃吸収材によるラジエータの冷却性能の低下を抑制しつつ、前突や歩行者衝突時における衝撃吸収性能の低下を防止する車両のフロントバンパユニットを提供する。【解決手段】ラジエータの前方に配設されるバンパビーム(32)と、バンパビームの前側に左右方向に移動可能に配設される衝撃吸収部材(39)と、バンパビーム及び衝撃吸収部材を車両の前方から覆うバンパフェイシア(50)と、衝撃吸収部材を移動させる衝撃吸収部材移動手段(60)と、バンパフェイシアへの被衝突体(80)の衝突を検出する衝突検出手段(70L,70R)と、衝突検出手段からの情報に基づき衝撃吸収部材移動手段を制御可能な制御手段(90)とを備えて構成され、制御手段は、該衝突検出手段からの情報に基づき被衝突体の衝突位置を判定し、該衝突位置に応じて該衝突位置に対応する位置に衝撃吸収部材を移動させる。【選択図】図5
