Abstract

본 발명은 자동차의 에어백 폭발시 연료펌프 작동 제어장치에 관한 것으로서, 종래의 차량에는 사고시 연료탱크의 누유를 막기위한 별도의 장치나 연료펌프의 작동을 중단하게 하는 장치가 설치되지 않아 사고차량이 화재로 부터 개방되게 하는 문제점이 있었다. 에어백 컨트롤유니트(10)가 에어백(20)의 인플레이터 (Inflator)를 폭발하게 하는 신호를 R/S래치(40)에 입력되게 설치하되, 상기 R/S래치(40)가 트랜지스터(TR)에 의하여 신호를 증폭하여 릴레리(50)를 작동하게 하므로서, 상기 릴레이(50)가 연료펌프의 전원공급을 차단 할 수 있도록 구성한다. 즉, 에어백(20)의 인플레이터(70)(Inflator)를 폭발하게 하는 신호를 입력받은 R/S래치(40)는 연료펌프전원을 제어하는 릴레이(50)를 작동하여 연료펌프가 구동되지 못하도록 구성된다. 이와같이, 본 발명을 이용한 자동차는 에어백이 작동하는 정도의 각종사고로 부터 연료펌프의 동작을 제한하여 누유에 의한 사고차량의 화제를 방지하게 하는 효과가 있다.The present invention relates to a fuel pump operation control device when the airbag explosion of the vehicle, the conventional vehicle is not provided with a separate device for preventing the leakage of the fuel tank in the event of an accident or the device to stop the operation of the fuel pump accident vehicle fire There was a problem to open from. The airbag control unit 10 is installed so that the signal to cause the inflator of the airbag 20 to be exploded into the R / S latch 40, wherein the R / S latch 40 is driven by the transistor TR. By amplifying the signal to operate the relay 50, the relay 50 is configured to cut off the power supply of the fuel pump. That is, the R / S latch 40 that receives the signal to explode the inflator 70 of the airbag 20 is configured to operate the relay 50 to control the fuel pump power so that the fuel pump cannot be driven. do. As described above, the vehicle using the present invention has an effect of preventing the topic of the accident vehicle due to leakage by limiting the operation of the fuel pump from various accidents of the degree of operation of the airbag.

Claims

In the air pump explosion control device of the vehicle, the airbag control unit is installed so that the airbag control unit to explode the inflator of the airbag to be input to the R / S latch, the R / S latch is signaled by the transistor Fuel pump operation control device in the event of an air bag explosion, characterized in that the relay is configured to cut off the power of the fuel pump by amplifying the relay to operate.
