Description

차량의 연료 공급 차단 장치Vehicle fuel cut off device

본 발명은 차량의 연료 공급 차단 장치에 관한 것으로서, 특히 차량 충돌 사고 발생시 연료 누설로 인한 화재 발생을 막기 위하여 다단계의 페일 세이프 구조에 의해 연료를 차단하는 차량의 연료 공급 차단 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel supply cutoff apparatus of a vehicle, and more particularly, to a fuel supply cutoff apparatus of a vehicle which cuts off fuel by a multi-level fail-safe structure in order to prevent a fire caused by fuel leakage when a vehicle crash occurs.

도 1은 종래 기술의 일실시예에 따른 연료 공급 차단 장치를 나타낸 개략도이다.1 is a schematic view showing a fuel supply blocking device according to an embodiment of the prior art.

도 1에 도시된 바와 같이 대한민국 특허청에 출원된 특허출원번호 제95-58571호 "연료공급 차단장치"는, 충돌센서(2)와 속도센서(3)를 통해 에어백 A를 작동시키는 에어백 전자제어장치(4)와, 상기 전자제어장치(4)에 의해 전원이 인가될 때 동작하므로써 연료 파이프를 차단하도록 설치된 솔레노이드 밸브부재(6)를 포함하여 이루어짐을 특징으로 한다.As shown in FIG. 1, Patent Application No. 95-58571, "Fuel Supply Blocking Device," filed with the Korean Intellectual Property Office, operates an airbag electronic control device for operating the airbag A through the collision sensor 2 and the speed sensor 3. (4) and a solenoid valve member (6) installed to shut off the fuel pipe by operating when power is applied by the electronic controller (4).

상기 솔레노이드 밸브부재(6)는 연료 파이프의 망 플레이트에 설치되는 솔레노이드 밸브(SL)와, 상기 솔레노이드 밸브(SL)의 작동에 의해 연동하므로써 차단 포트의 포트 시이트에 밀착하여 차단하도록 하는 차단 플레이트(12)를 포함하여 이루어진다.The solenoid valve member 6 is connected to the solenoid valve SL installed on the mesh plate of the fuel pipe by the operation of the solenoid valve SL so that the solenoid valve member 12 closes and closes against the port sheet of the blocking port. )

반면, 도시되진 않았지만 특허출원번호 제95-056067호 "자동차의 연료펌프 제어장치"는, 차의 시동상태, 엔진의 회전 상태 및 엔진오일의 압력에 따른 신호를 출력하는 엔진제어모듈과, 상기 엔진제어모듈의 출력에 따라 전원전류의 공급을 단속하는 릴레이와, 상기 릴레이의 접속에 의해 공급된 전원전류로 구동되는 펌핑모터로 구성된 자동차의 연료펌프 제어장치에 있어서, 차에 충돌사고가 발생하면 상기 펌핑모터로 공급되는 전원이 차단되도록 상기 릴레이와 상기 펌핑모터와의 사이에 차의 충돌을 감지하는 충돌감지센서를 접속시켜서 됨을 특징으로 한다.On the other hand, although not shown in the patent application No. 95-056067 "car fuel pump control device", the engine control module for outputting a signal according to the starting state of the car, the rotational state of the engine and the pressure of the engine oil, and the engine In the fuel pump control apparatus of a vehicle comprising a relay for controlling the supply of the power current according to the output of the control module, and a pumping motor driven by the power current supplied by the connection of the relay, when the collision occurs in the vehicle, It is characterized in that the collision detection sensor for detecting a collision of the car between the relay and the pumping motor so that the power supplied to the pumping motor is cut off.

그러나, 상술한 바와 같은 종래의 연료 공급 차단 장치들은 차량의 충돌이 감지된 후 연료의 공급을 차단하기 위한 수단을 구비하고 있긴 하지만, 페일 세이프 개념(Fail Safe)을 적용하고 있지 못하다.However, although the conventional fuel supply cutoff devices as described above are provided with a means for shutting off the supply of fuel after a collision of the vehicle is detected, it does not apply a fail safe concept.

즉, 차량 충돌로 인해 연료공급 차단수단 자체가 손상을 받은 경우에는 차량 충돌이 감지되더라도 연료가 정상적으로 차단될 수 없으며, 이로인해 연료 공급 라인 중 어느 한 부분에서 누설이 시작된다면 차량 화재 혹은 폭발과 같은 2차적인 피해를 입게 되는 문제점이 있었다.In other words, if the fuel supply blocking means itself is damaged due to a vehicle collision, the fuel cannot be blocked normally even when a vehicle collision is detected. Therefore, if a leakage starts at any part of the fuel supply line, a vehicle fire or explosion may occur. There was a problem of secondary damage.

상기와 같은 문제점을 해결하기 위하여 본 발명의 목적은 차량 사고 발생후 연료 누설로 인한 화재 발생을 원천적으로 방지하기 위하여 다단계에 걸쳐 연료의 공급을 차단할 수 있는 장치를 제공하는데 있다.SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide a device that can cut off the supply of fuel in multiple stages in order to prevent the occurrence of fire due to fuel leakage after the vehicle accident.

참조부호 10은 충돌 감지 센서로서, 차량의 충격가속도를 감지하여 충돌감지신호를 출력한다. 상기 충돌 감지 센서 10은 차량 전방 양쪽에 설치되어 전방충돌감지신호를 출력하는 전방 충격가속도 센서와, 차량 중앙에 설치되어 중앙충돌감지신호를 출력하는 중앙 충격가속도 센서로 구성된다.Reference numeral 10 denotes a collision detection sensor and detects an impact acceleration of the vehicle and outputs a collision detection signal. The collision detection sensor 10 includes a front impact acceleration sensor installed at both sides of the front of the vehicle and outputting a front collision detection signal, and a central impact acceleration sensor installed at the center of the vehicle and outputting a central collision detection signal.

상기 전방 충격가속도 센서의 예로서는 편심회전 매스를 갖는 기계식 가속도 센서를 사용할 수 있으며, 편심회전 매스를 장치한 로터 플레이트, 회전 접점, 고정 접점 및 코일 스프링으로 이루어진다. 상기 중앙 충격가속도 센서의 예로서는 가속도 센서 칩을 내장한 가속도 센서를 사용할 수 있으며, 캔틸레버를 구비한 가속도 센서 칩, 실리콘 오일 및 캔 케이스로 이루어진다.As an example of the front impact acceleration sensor, a mechanical acceleration sensor having an eccentric rotational mass may be used, and includes a rotor plate equipped with an eccentric rotational mass, a rotational contact, a fixed contact, and a coil spring. An example of the central shock acceleration sensor may be an acceleration sensor incorporating an acceleration sensor chip, and includes an acceleration sensor chip having a cantilever, silicon oil, and a can case.

참조부호 20은 차속 감지 센서로서, 휠 일측에 장착되어 차속감지신호를 출력한다. 상기 차속 감지 센서(20)으로는 주로 주파수 검출형 센서 혹은 자기 저항 소자식 센서를 사용한다.Reference numeral 20 is a vehicle speed sensor, which is mounted on one side of the wheel and outputs a vehicle speed detection signal. The vehicle speed detecting sensor 20 mainly uses a frequency detecting sensor or a magnetoresistive element type sensor.

참조부호 30은 제어기로서, 상기 충돌감지신호와 차속감지신호의 입력에 응답하여 차량이 충돌로 인하여 정지하였음을 판단하면 밸브차단신호, 펌핑중지신호 및 분사정지신호를 출력한다.Reference numeral 30 is a controller, and when it is determined that the vehicle has stopped due to a collision in response to the input of the collision detection signal and the vehicle speed detection signal, it outputs a valve cutoff signal, a pumping stop signal, and an injection stop signal.

상기 제어기의 제어 과정을 도 2 및 도 3을 참조하여 살펴보면 다음과 같다.The control process of the controller will now be described with reference to FIGS. 2 and 3.

101과정에서 상기 제어기(30)는 충돌 감지 센서(10)로부터 출력된 충돌감지신호에 의해 차량에 충돌이 있었음을 감지하고, 감지된 충격이 미리 설정된 기준 이상의 충돌인지를 판단한다.In step 101, the controller 30 detects that there is a collision in the vehicle by the collision detection signal output from the collision detection sensor 10, and determines whether the detected shock is a collision exceeding a preset reference.

상기 충돌 판단 과정에서 기준 이상의 충돌이 있었음을 판단하면, 102과정에서 차속 감지 센서(20)로부터 출력된 차속감지신호에 의해 차량이 정지되었는가를 판단한다. 이어, 상기 정지 판단 과정에서 차량이 정지되었음을 판단하면, 103과정에서 연료 차단 밸브(40)로 밸브차단신호를 출력한다.When it is determined that there is a collision higher than the reference in the collision determination process, it is determined whether the vehicle is stopped by the vehicle speed detection signal output from the vehicle speed sensor 20 in step 102. Subsequently, if it is determined that the vehicle is stopped in the stop determination process, the valve shutoff signal is output to the fuel shutoff valve 40 in step 103.

만일, 상기 정지 판단 과정에서 차량이 진행중임을 판단하면 차량이 정지될 때까지 밸브차단신호의 출력을 유보한다. 이와같이 밸브차단신호의 출력을 유보하는 이유는 차량 충격후 도로 한편으로 차를 주차시키는 등 임시 조치를 위해 필요한 차량 구동 시간을 확보하기 위함이다.If it is determined that the vehicle is in progress in the stop determination process, the output of the valve blocking signal is reserved until the vehicle is stopped. The reason why the output of the valve cutoff signal is reserved is to secure vehicle driving time necessary for temporary measures such as parking a car on one side of the road after the impact of the vehicle.

또한, 상기 제어기(30)는 밸브차단신호의 출력 후 104과정에서 연료 펌프(50)로 펌핑중지신호를 출력하고, 이어 105과정에서 연료 분사기(60)로 분사정지신호를 출력한다.In addition, the controller 30 outputs a pumping stop signal to the fuel pump 50 in step 104 after outputting the valve cutoff signal, and then outputs an injection stop signal to the fuel injector 60 in step 105.

참조부호 40은 연료 차단 밸브로서, 연료 탱크와 연료 펌프 사이를 연결하는 연료 파이프 내측에 설치된다. 상기 연료 차단 밸브(40)은 밸브차단신호 입력시 상기 연료 파이프를 차단하는 솔레노이드 밸브로 구성한다.Reference numeral 40 is a fuel shutoff valve, which is installed inside the fuel pipe connecting the fuel tank and the fuel pump. The fuel shutoff valve 40 is configured as a solenoid valve that shuts off the fuel pipe when a valve shutoff signal is input.

참조부호 50은 연료 펌프로서, 배터리(전원부)로부터 구동전압을 공급받아 아래쪽에 설치된 연료탱크에서 위쪽에 설치된 기화기(또는 연료분사장치)로 연료가 이동할 수 있도록 펌핑 역할을 한다.Reference numeral 50 denotes a fuel pump, which receives a driving voltage from a battery (power supply unit) and pumps the fuel to move from a fuel tank installed below to a vaporizer (or fuel injection device) installed above.

참조부호 60은 연료 분사기로서, 상기 제어기(30)로부터 공급되는 신호(전류)에 의해 개폐되는 분사밸브를 구비한다. 상기 분사밸브의 솔레노이드 코일에 전류가 흐르면 밸브 니들이 흡인되어 분사밸브의 출구가 열리고, 비로소 연료가 분사되기 시작한다. 반대로 상기 솔레노이드 코일에 전류가 차단되면, 밸브 니들이 분사밸브의 출구와 밀착되어 연료가 분사되지 않는다.Reference numeral 60 denotes a fuel injector, which includes an injection valve opened and closed by a signal (current) supplied from the controller 30. When a current flows through the solenoid coil of the injection valve, the valve needle is sucked to open the outlet of the injection valve and fuel starts to be injected. On the contrary, when the current is blocked in the solenoid coil, the valve needle is in close contact with the outlet of the injection valve, and the fuel is not injected.

즉, 본 발명의 특징에 따른 차량의 연료 공급 차단 장치는, 설정된 기준 이상의 차량 충돌이 있은 후 차량이 정지함을 판단한 제어기(30)이 연료 차단 밸브 (40), 연료 펌프(50), 연료 분사기(60)로 연료를 차단하기 위한 제어신호를 출력함으로써 연료 누설로 인한 화재 등을 방지한다.That is, in the fuel supply cutoff apparatus of the vehicle according to the aspect of the present invention, the controller 30 that determines that the vehicle is stopped after the vehicle collision exceeds the set reference is determined by the fuel shutoff valve 40, the fuel pump 50, and the fuel injector. A control signal for cutting off fuel is output to 60 to prevent a fire or the like due to fuel leakage.

상술한 바와 같이 본 발명의 실시예에 따른 차량의 연료 공급 차단 장치는 차량에 사고가 발생하더라도 다단계에 걸쳐 연료 공급을 차단함으로써 연료 누설로 인한 차량의 화재 및 폭발과 같은 위험을 방지할 수 있는 효과가 있다.As described above, the fuel supply cutoff apparatus of the vehicle according to the embodiment of the present invention is capable of preventing a risk such as a fire and an explosion of the vehicle due to fuel leakage by cutting off the fuel supply in multiple stages even if an accident occurs in the vehicle. There is.
