Abstract

본 발명은 차량 주행시 타차량 또는 기타 장애물에 충돌하였을 경우, 충돌 순간 차량이 자동적으로 정지할 수 있도록 한 차량충돌시 2차충돌 방지용 자동 브레이크 시스템에 관한 것으로, 충격감지 센서(10)가 신호증폭부(20)에 연결되고, 상기 증폭부(20)의 출력측이 신호처리부(30)의 입력측에 연결되며, 상기 신호처리부(30)의 출력측이 유압콘트롤러(40)의 입력측에 연결되고, 상기 유압콘트롤러(40)의 출력측이 방향전환밸브(50)의 제어단자(a)에 연결되되, 유압원(60)의 유압이 상기 방향전환밸브(50)를 통해 마스터 실린더(2)내의 피스톤(3)을 전,후진시키도록 연결구성되어 차량 주행시 타차량 또는 기타 장애물에 충돌하였을 경우, 운전자가 브레이크를 밟을 수 없는 상태가 되더라도 충격감지 센서를 통해 충돌을 감지하고, 유압원의 유압이 마스터 실린더를 작동시켜 차량이 자동적으로 정지되도록 함으로써 차량의 제2, 제3충돌을 미연에 방지하여 운전자 및 차량의 피해를 최소화시킬 수 있고, 에어백이 장착된 차량일 경우에도 에어백의 효과를 극대화 할 수 있도록 하는데 그 특징이 있다.The present invention relates to an automatic brake system for preventing a secondary collision when a vehicle crashes so that when a vehicle collides with another vehicle or other obstacle while driving, the impact sensor 10 includes a signal amplifier. (20), the output side of the amplifier 20 is connected to the input side of the signal processor 30, the output side of the signal processor 30 is connected to the input side of the hydraulic controller 40, the hydraulic controller The output side of the (40) is connected to the control terminal (a) of the diverter valve (50), the hydraulic pressure of the hydraulic source (60) to the piston (3) in the master cylinder (2) through the diverter valve (50) It is configured to move forward and backward so that if the vehicle collides with other vehicles or other obstacles while driving, it detects the collision through the shock sensor even when the driver cannot press the brake. By operating the vehicle to stop automatically, it prevents the second and third collisions of the vehicle in advance, thereby minimizing the damage to the driver and the vehicle, and also maximizes the effect of the airbag even in a vehicle equipped with an airbag. It has its features.
