Summary:PURPOSE: A shock absorber is provided to release a brake system for a while and brake again by adding effort of a brake pedal in a rear-end collision of a vehicle at a stop. CONSTITUTION: A shock detecting sensor(21) of a vehicle at a stop detects the impact and applies to an ECU(Electronic Control Unit)(22) at a rear-end collision in waiting for a signal change with full effort of a brake pedal. The ECU opens a solenoid valve(23) mounted in front and rear wheel brake lines, and lowers pressure of brake oil in a brake system. The vehicle absorbs the impact from the back with being pushed forward by releasing the locked brake temporarily. An obstacle detecting sensor(20) detects a front obstacle and applies to the ECU in case of being vehicles or obstacles in front of the vehicle. The stop vehicle is prevented from being bumped into the front obstacle due to the inoperative solenoid valve against the impact from the following vehicle. 본 발명은 자동차의 제동장치에 관한 것이며, 특히는 정지하고 있는 자동차의 후부에 달려오던 자동차가 추돌되었을 때 정지해 있던 자동차의 탑승자에게 충격을 최소화하는 후방 추돌시 충격완화장치에 관한 것이다. 본 발명은 주브레이크장치에 있어서, 상기 주브레이크장치의 전,후륜 브레이크 라인에 설치된 솔레노이드밸브(23), 상기 솔레노이드밸브(23)에 연결된 ECU(22), 상기 ECU(22)에 연결되며 자동차의 후방에 설치된 후방충격감지센서(21) 및 자동차의 전방에 설치된 전방장애물감지센서(20)를 구성함으로써, 브레이크페달에 답력을 가하여 정차해 있을 때 자동차의 후방에서 다른 자동차가 달려와 충돌하게 되면 정지해 있는 자동차의 브레이크장치가 일시적으로 릴리스되면서 충격을 흡수하여 탑승자의 안전을 도모할 수 있는 후방 추돌시 충격완화장치를 제공할 수 있게 된다.
