Summary:The present invention provides a shock attenuation device mounted as a module on a frame of a vehicle, the device comprising: a speed sensor for detecting the driving speed of a vehicle; a distance detection sensor for measuring the distance between the vehicle and an object in front of or behind the vehicle; a shock detection determination unit for determining, on the basis of the driving speed of the vehicle and information on the distance from the object, whether it is possible for the vehicle and the object to collide; a buffer cylinder; a piston which is provided to be movable inside the buffer cylinder and has a shock-absorbing bumper connected to the front thereof; and a gas generation device provided inside the buffer cylinder to be adjacent to a head of the piston at the rear of the buffer cylinder. La présente invention concerne un dispositif d'atténuation de choc monté en tant que module sur un châssis d'un véhicule, le dispositif comprenant : un capteur de vitesse permettant de détecter la vitesse de conduite d'un véhicule ; un capteur de détection de distance permettant de mesurer la distance entre le véhicule et un objet devant ou derrière le véhicule ; une unité de détermination de détection de choc permettant de déterminer, sur la base de la vitesse de conduite du véhicule et d'informations sur la distance vis-à-vis de l'objet, s'il est possible que le véhicule et l'objet entrent en collision ; un vérin amortisseur ; un piston qui est prévu pour être mobile à l'intérieur du vérin amortisseur et qui comporte un pare-chocs amortisseur relié à l'avant de celui-ci ; et un dispositif de génération de gaz disposé à l'intérieur du vérin amortisseur de sorte à être adjacent à une tête du piston à l'arrière du vérin amortisseur. 본 발명은 자동차의 프레임에 모듈로 장착되는 충격 감쇄 장치로서, 상기 충격 감쇄 장치는: 차량의 주행 속도를 검출하는 속도센서; 차량과 차량 전방 또는 후방의 물체와의 거리를 측정하는 거리감지센서; 차량의 주행 속도와 물체와의 거리 정보를 토대로 차량과 물체와의 충돌 가능성 여부를 판단하는 충돌감지판단부; 완충실린더; 상기 완충실린더 내부에서 이동 가능하도록 설치되며 전방에 충격 흡수용 범퍼가 연결된 피스톤; 및 완충실린더의 후방에 피스톤의 헤드와 인접하여 완충실린더의 내부에 설치된 가스발생장치로 이루어지는, 충격 감쇄 장치를 제공한다.
