본 발명은 자동차 연료캡 미장착시 시동불능 및 경고장치에 관한 것으로, 특히 자동차 연료주입구 캡의 개폐를 검출하도록 연료캡 스위치를 설치하고 이로부터의 신호를 처리하여 자동차의 시동을 제어하고, 연료캡이 개방되었음을 경고하고 위한 장치에 관한 것이다.The present invention relates to an inability to start and warning device when a vehicle fuel cap is not installed. In particular, a fuel cap switch is installed to detect the opening and closing of a vehicle fuel inlet cap, and a signal from it is controlled to control the starting of the vehicle. It relates to a device for warning that it has been opened.
일반적으로 자동차의 연료주입구는 차체 후방에 배치되어 있으므로 주유소등에서 연료를 주입하고 나서 캡을 다시 닫았는지 여부를 운전자가 확인하기에 어려움이 있고 만일 연료주입후 캡을 닫지않고 출발하였을 때 운전중 연료탱크내의 연료가 차의 진동으로 넘쳐 흘러 주위를 오염시키거나 누출된 연료가 불꽃에 의해 인화되어 차량의 화재로 이어지는 위험성이 있다.In general, it is difficult for the driver to check whether the cap is closed again after injecting fuel at a gas station, etc. There is a danger that the fuel in the vehicle overflows with the vibration of the car, polluting the surroundings, or the leaked fuel is ignited by the flame, leading to the fire of the vehicle.
따라서 본 발명은 위와같은 문제점을 해결하기 위한 것으로, 연료캡과 주입구 사이에 연료캡 닫힘여부를 감지하는 스위치를 장착하고 이 스위치의 오프신호에 따라 시동모터의 동작을 금지시키는 동시에 계기판의 경고등에 연료캡 열림경고등을 동작시켜 운전자로 하여금 연료캡의 미장착 상태를 알려줄 수 있는 장치를 제공함에 그 목적이 있다.Therefore, the present invention is to solve the above problems, equipped with a switch for detecting whether the fuel cap is closed between the fuel cap and the inlet, and prohibits the operation of the starting motor in accordance with the off signal of the switch at the same time the fuel warning lamp of the instrument panel It is an object of the present invention to provide a device that can inform the driver of the fuel cap is not mounted by operating the cab opening warning light.
본 발명에 따르면, 자동차 연료캡과 연료주입구사이에서 연료캡의 장착여부에 따라 스위치가 온/오프 되도록 연료캡 스위치를 장착하고, 이 스위치의 온/오프에 의해 회로동작전압 또는 접지레벨을 검출하도록 자동차 전자제어장치의 1입력단에 상기스위치가 연결되고, 전자제어장치의 1출력단은 시동모터구동릴레이를 통해 스타터모터와 연결되는 동시에 또하나의 출력단에서 스위칭 트랜지스터를 통해 전원전압을 공급받는 표시램프를 연결하여 구성되고, 상기 전자제어장치가 연료캡 스위치의 오프상태에 반응하여 시동모터 구동신호의 발생을 중지시킴과 동시에 경고램프구동신호를 발생하여 램프를 점등시키는 연료캡 미장착시 시동불능 및 경고장치가 제공된다.According to the present invention, the fuel cap switch is mounted so that the switch is turned on / off according to whether the fuel cap is mounted between the vehicle fuel cap and the fuel inlet, and the circuit operating voltage or the ground level is detected by turning on / off the switch. The switch is connected to one input terminal of the electronic control device of the vehicle, and the one output terminal of the electronic control device is connected to the starter motor through a starter motor relay and at the same time, a display lamp supplied with a power voltage through a switching transistor at another output terminal. And the electronic control device stops the generation of the starting motor drive signal in response to the off state of the fuel cap switch and at the same time generates a warning lamp driving signal to start the lamp when the fuel cap is not mounted. Is provided.
바람직하게, 상기 경고램프는 운전석앞의 계기판에 설치된다.Preferably, the warning lamp is installed on the instrument panel in front of the driver's seat.
상기한 본 발명의 목적과 특징 및 장점을 이해하기 쉽도록 이하 첨부도면을 참고하여 본 발명의 일 실시예에 대해 상세히 설명한다.To facilitate understanding of the objects, features and advantages of the present invention described above, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제2도를 참조하면, 본 발명에 따른 연료캡 미장착시 시동불능 및 경고장치의 전기회로도가 도시되어 있다. 자동차 전자제어장치(10)의 1입력단에 회로동작전압 Vcc과 접지레벨 사이의 어느하나를 검출하는 스위치 SW1가 연결되어 있다. 스위치 SW1는 제1도에 나타낸 것과 같이 자동차 연료캡(4)과 연료주입구(5) 사이에서 연료캡(4)의 장착여부에 따라 온/오프 되도록 장착된다.Referring to FIG. 2, there is shown an electrical circuit diagram of a non-startup and warning device when no fuel cap is mounted in accordance with the present invention. A switch SW1 for detecting any one between the circuit operating voltage Vcc and the ground level is connected to one input terminal of the vehicle electronic control apparatus 10. The switch SW1 is mounted so as to be turned on / off depending on whether the fuel cap 4 is mounted between the vehicle fuel cap 4 and the fuel inlet 5 as shown in FIG.
상기 전자제어장치(10)의 1출력단은 통상의 시동모터구동용 릴레이 RY가 연결되고 이 릴레이의 스위치를 통해 전원전압이 스타터모터(20)로 공급되도록 연결되어 있다. 전자제어장치(10)의 또하나의 출력단은 스위칭 트랜지스터를 통해 전원전압을 공급받는 표시램프 L1가 연결되어 있다.One output terminal of the electronic control apparatus 10 is connected to a normal starting motor driving relay RY and supplied with a power supply voltage to the starter motor 20 through a switch of the relay. Another output terminal of the electronic controller 10 is connected to a display lamp L1 that receives a power supply voltage through a switching transistor.
도면에서, SW2는 클러치페달의 작동에 반응하는 스위치를 나타낸다.In the figure, SW2 represents a switch in response to the operation of the clutch pedal.
이와같은 회로에서, 연료캡 스위치 SW1가 오프상태, 즉 미장착 상태이면 전자제어장치(10)는 시동모터 구동신호의 발생을 중지시켜 그 1출력단의 스위칭 트랜지스터를 턴 오프시키게 되고, 운전자가 엔진점화키스위치(도시생략)를 작동시키더라도 릴레이 RY가 동작되지 않으므로 시동이 불가능하게 된다.In such a circuit, if the fuel cap switch SW1 is in an off state, that is, not mounted, the electronic control device 10 stops the generation of the start motor drive signal and turns off the switching transistor of the first output stage. Even if the position (not shown) is operated, the relay RY does not operate, so starting is impossible.
한편 전자제어장치(10)는 연료캡 스위치 SW1의 오프상태에 반응하여 또 하나의 출력단에서 경고램프구동신호를 발생하고, 이에 의해 스위칭 트랜지스터를 턴 온 시키고 따라서 전원전압 Vcc이 램프 L1으로 공급되게 하여 경고등을 점등시킨다. 이 램프 L1은 바람직하게 운전석의 클러스터에 설치되어 운전자가 이 램프의 점등에 의해 연료 캡(4)의 미장착 상태를 인지할 수 있게 된다.On the other hand, the electronic controller 10 generates a warning lamp driving signal at another output terminal in response to the off state of the fuel cap switch SW1, thereby turning on the switching transistor so that the power supply voltage Vcc is supplied to the lamp L1. Turn on the warning lamp. This lamp L1 is preferably installed in the cluster of the driver's seat so that the driver can recognize the unmounted state of the fuel cap 4 by the lighting of this lamp.
이상 설명한 바와 같이 본 발명에 의하면, 연료캡과 주입구 사이에 연료캡 닫힘 여부를 감지하는 스위치를 장착하고 이 스위치의 오프신호에 따라 시동모터의 동작을 금지시키는 동시에 계기판의 경고등에 연료캡 열림경고등을 점등시켜 운전자가 연료캡의 미장착 상태를 알 수 있게 되는 효과가 있다.As described above, according to the present invention, a switch for detecting whether the fuel cap is closed between the fuel cap and the inlet is mounted, and the fuel cap opening warning light is applied to the warning lamp of the instrument panel while prohibiting the operation of the starting motor according to the off signal of the switch. It turns on so that the driver can know the fuel cap is not installed.
