본 발명은 차량에 설치된 헤드램프의 점등을 제어하는 장치에 관한 것으로, 특히 차량이 주행중 터널이나 지하도와 같은 어두운 곳에 진입할 경우 헤드램프가 자동적으로 점등되게 하므로써 안전운전에 도움을 줄 수 있도록 한 차량의 헤드램프 제어장치에 관한 것이다.The present invention relates to a device for controlling the lighting of a headlamp installed in a vehicle. In particular, when the vehicle enters a dark place such as a tunnel or an underground road while driving, the headlamp is automatically turned on to assist in safe driving. Relates to a headlamp control device.

일반적으로 자동차의 야간 주행에 시야를 확보하기 위해 설치되어 있는 헤드램프는, 운전자가 헤드램프스위치를 조작하여 on작동시키도록 되어 있고, 이 헤드램프 스위치를 별도로 off작동시키지 않으면 소등되지 않도록 되어 있다.In general, a headlamp provided to secure a vision at night driving of a vehicle is designed to be operated by a driver by operating a headlamp switch, and is not turned off unless the headlamp switch is separately turned off.

그러나, 통상 자동차가 주간에 주행하는 경우에 헤드램프를 소등시킨 상태에서 주행하게 되므로, 조명이 어두운 터널이나 지하도를 통과할 때 운전자는 안전운행을 위해 수동으로 스위치를 조작하여 헤드램프를 점등시켜야 하고, 또한 터널이나 지하도를 통과한 뒤에는 다시 스위치를 조작하여 헤드램프를 소등시켜야 하는 번거로움이 있을뿐 아니라 운전자가 터널이나 지하도를 통과후 헤드램프의 점등상태를 잊고서 소등하지 않은 채 주행하게 되는 등의 문제점이 있다.However, in general, when the vehicle is driven during the day, the headlamp is turned off, so when the driver passes a tunnel or underpass where the lighting is dark, the driver has to manually switch on the headlamp for safe driving. In addition, after passing through the tunnel or underpass, it is not only a hassle to turn off the headlamp by operating the switch again, but after the driver passes through the tunnel or underpass, the driver forgets the lighting state of the headlamp and runs without turning off. There is a problem.

그러나, 일반적인 차량에서는 헤드램프를 소등시키기 위해서는 헤드램프스위치를 off시켜야만 하므로 그 조작에 번거로움이 있고, 잠깐 동안 정차한 후에 차량이 다시 출발하는 경우에는 상기 헤드램프스위치를 다시 점등시켜야 하므로 이중적인 불편함이 있는 것이다.However, in a typical vehicle, the headlamp switch must be turned off in order to turn off the headlamp. Therefore, it is inconvenient to operate the headlamp switch. Is there.

이에 본 발명은 상기한 바와 같은 문제점을 해소시키기 위해 안출된 것으로, 차량이 주행중에 주위의 조도상황에 의해 자동으로 헤드램프가 점등 내지는 소등 제어되도록 한 차량의 헤드램프 점등제어장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, to provide a head lamp lighting control device of the vehicle so that the head lamp is turned on or off automatically controlled by the ambient light conditions while the vehicle is running. There is this.

상기한 바의 목적을 달성하기 위한 본 발명은, 헤드램프와, 차량주위의 조도상태에 따라 점등신호를 입력하게 된 점등수단, 상기 점등수단의 출력을 입력받아 이그니션스위치가 온이고 헤드램프스위치가 오프일 때 상기 헤드램프를 점등시키도록 제어전류를 출력하게 된 엔드게이트로 구성된 것을 특징으로 한다.In order to achieve the above object, the present invention provides a head lamp, lighting means for inputting a lighting signal according to the illumination condition around the vehicle, and an ignition switch is turned on by receiving an output of the lighting means. And an end gate configured to output a control current to turn on the head lamp when the head lamp is turned off.

이러한 구조로 이루어진 본 발명의 장치는 주간에 헤드램프스위치를 소등시킨 상태에서 주행을 하다가 터널이나 지하도 등과 같이 어두운 곳을 통과할 때 차량의 헤드램프가 자동으로 점등되고, 이어서 상기 어두운 곳을 통과하여 밝은 지역으로 나올 때는 다시 헤드램프가 소등되도록 하게 해준다.In the apparatus of the present invention having such a structure, the headlamp of the vehicle is automatically turned on when the vehicle passes through a dark place such as a tunnel or an underpass while the headlamp switch is turned off during the day, and then passes through the dark place. When you come out into a bright area, let the headlamp go out again.

이와같이 운전자가 헤드램프스위치를 별도로 조작함이 없이 헤드램프를 주위의 조도상황에 따라 점소등되게 하므로써, 편리함을 도모함과 더불어 안전운전을 도모할 수가 있는 것이다.In this way, the driver can turn the headlamp on and off according to the ambient light conditions without operating the headlamp switch separately, thereby achieving convenience and safe driving.

이하 본 발명을 첨부한 예시도면을 참조하여 자세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

제1도는 본 발명에 따른 장치를 구현하는 전기회로도를 도시한 것으로서, 헤드램프(10)와, 차량주위의 조도상태에 따라 점등신호를 입력하게 된 점등수단(20), 상기 점등수단(20)의 출력을 입력받아 이그니션스위치가 온이고 헤드램프스위치가 오프일 때 상기 헤드램프(10)를 점등시키도록 제어전류를 출력하도록 된 앤드게이트(30)로 구성되어 있다.1 shows an electric circuit diagram for implementing an apparatus according to the present invention, wherein the headlamp 10, a lighting means 20 for inputting a lighting signal according to the illuminance state around the vehicle, and the lighting means 20 And an gate gate 30 configured to output a control current to turn on the head lamp 10 when the ignition switch is turned on and the head lamp switch is turned off.

여기서, 상기 앤드게이트(30)는 주위의 조도상태에 따라 제어전류를 출력하는 점등수단(20)과, 이그니션스위치가 on되면 제어전류를 인가하게 된 이그니션스위치 접점(12) 및, 헤드램프스위치가 off되면 제어전류를 인가하게 된 헤드램프스위치 접점(14)이 입력측에 연결되고, 상기 입력측으로부터 제어전류가 모두 입력되는 경우 헤드램프(10)에 제어전류를 출력하여 점등시키게 된 것이다.Here, the AND gate 30 is a lighting means 20 for outputting a control current according to the ambient illumination condition, the ignition switch contact 12 for applying the control current when the ignition switch is turned on, and the headlamp switch When off, the head lamp switch contact 14 to which the control current is applied is connected to the input side, and when all the control currents are input from the input side, the head lamp switch contact 14 outputs the control current to the head lamp 10 to be turned on.

이때 상기 이그니션스위치 접점(12)은 a접점으로 연결되어 있어 이그니션스위치(미도시)가 동작하는 경우 닫히게 되어 밧데리(B+)로부터 상기 앤드게이트의 입력측에 high신호를 인가해주게 된 것이고,상기 헤드램프스위치 접점(14)은 b접점으로 연결되어 있어 헤드램프스위치(미도시)가 동작하는 경우에는 열리게 되므로써 헤드램프스위치에 의해 직접적으로 헤드램프(10)가 동작하는 경우에는 상기 앤드게이트(30)가 low신호를 출력하도록 된 것이다.In this case, the ignition switch contact point 12 is connected to a contact point and is closed when the ignition switch (not shown) is operated to apply a high signal from the battery B + to the input side of the end gate, and the headlamp The switch contact 14 is connected to a contact b so that the open gate is opened when the head lamp switch (not shown) operates, so that when the head lamp 10 is directly operated by the head lamp switch, the end gate 30 is closed. It is to output low signal.

한편, 상기 점등수단(20)은 주위가 밝을 때는 low신호를 출력하고, 주위가 어두울 때는 high신호를 출력하게 된 것으로, 주위의 조도에 따라 저항값이 가변되어 전류통과량을 제어하게 된 조도센서(22)와, 상기 조도센서(22)로부터 출력되는 전류를 입력받아 동작하게 된 포토커플러(24, 26) 및, 상기 포토커플러(26)의 출력신호를 역변환하여 앤드게이트(30)의 입력단자에 연결시켜 주게 된 인버터(28)로 구성되어 있다.On the other hand, the lighting means 20 outputs a low signal when the surroundings are bright, and outputs a high signal when the surroundings are dark. The illuminance sensor controls the current passing amount by varying the resistance value according to the ambient illumination. And an input terminal of the AND gate 30 by inverting the output signals of the photocouplers 24 and 26 and the photocouplers 26 which are operated by receiving the current output from the illuminance sensor 22. Inverter 28 is connected to the.

상기 조도센서(22)는 예컨대 황화카드뮴셀(CdS Cell)로 된 것으로, 주위가 밝으면 저항치가 줄어들어 전류를 흐르게하여 high신호를 출력하는 한편, 주위가 어두워지면 저항치가 커지면서 전류를 흐르지 않도록 되어 low신호를 출력하게 된 것이다.The illuminance sensor 22 is made of, for example, a cadmium sulfide cell (CdS Cell). When the ambient light is low, the resistance value decreases to flow a current to output a high signal, while when the ambient light becomes dark, the resistance value increases so that the current does not flow. It will output a signal.

그리고, 상기 포토커플러의 발광부(24)는 상기 조도센서(22)로 밧데리(B+)에 연결되어 있어 상기 조도센서(22)가 전류를 통과시키게 되면 동작하여 발광하게 되고, 이때 포토커플러의 수광부(26)는 상기 발광부(24)로부터 조사된 빛이 베이스단자로 입력되면 밧데리(B+)로부터 인가된 전류를 통과시켜 high신호를 출력하게 된다.In addition, the light emitting unit 24 of the photocoupler is connected to the battery B + by the illuminance sensor 22 so that the illuminance sensor 22 operates when the current passes, and emits light. When the light emitted from the light emitting unit 24 is input to the base terminal, the light receiving unit 26 outputs a high signal by passing a current applied from the battery B + .

또한, 상기 포토커플러의 수광부(26)로부터 출력된 제어전류는 상기 인버터(28)로 역변환되어 앤드게이트(30)의 입력측에 연결된다.In addition, the control current output from the light receiving unit 26 of the photocoupler is inversely converted into the inverter 28 and connected to the input side of the AND gate 30.

이와 같은 구성으로 된 본 발명의 헤드램프 점등제어장치의 동작은 다음과 같다.Operation of the headlamp lighting control device of the present invention having such a configuration is as follows.

차량을 주간에 주행하게 되는 경우, 즉 이그니션스위치가 on됨과 아울러 헤드램프스위치를 켠 상태에서 주행시에는, 상기 이그니션스위치 접점(12)이 on되므로써 엔드게이트(30)의 입력측에 high신호를 출력하게 되고, 또한 헤드램프스위치 접점(14)이 on되므로써 상기 앤드게이트(30)의 다른 입력측에 high신호를 출력하게 된다.When the vehicle is driven during the day, that is, when the ignition switch is turned on and the head lamp switch is turned on, the ignition switch contact 12 is turned on to output a high signal to the input side of the end gate 30. In addition, the head lamp switch contact 14 is turned on to output a high signal to the other input side of the AND gate 30.

따라서 상기 앤드게이트(30)는 또 다른 입력측에 연결된 점등수단(20)에 의해 헤드램프(10)의 점등 및 소등을 제어하게 되는 바, 상기 점등수단(20)으로부터 high신호가 입력되면 헤드램프(10)를 점등시키게 되고, 상기 점등수단(20)으로부터 low신호가 입력되면 헤드램프(10)를 소등시키게 된다.Therefore, the AND gate 30 controls the lighting and turning off of the head lamp 10 by the lighting means 20 connected to another input side. When the high signal is input from the lighting means 20, the head lamp ( 10) is turned on, and when the low signal is input from the lighting means 20, the headlamp 10 is turned off.

즉 차량이 주위가 어두운 터널이나 지하도를 헤드램프스위치를 off시킨 상태에서 통과하는 경우에 상기 점등수단(20)이 high신호를 앤드게이트(30)의 입력측에 출력하여 헤드램프(12)가 점등되고, 다시 차량이 터널이나 지하도를 통과하여 주위가 밝아지면 상기 점등수단(20)이 low신호를 앤드게이트(30)의 입력측에 출력하므로써 헤드램프(10)가 소등되게 제어하게 된다.That is, when the vehicle passes through a tunnel or underpass with the headlamp switch turned off, the lighting means 20 outputs a high signal to the input side of the AND gate 30 so that the headlamp 12 is turned on. When the vehicle becomes bright again by passing through the tunnel or the underpass, the lighting means 20 outputs a low signal to the input side of the AND gate 30 so that the headlamp 10 is turned off.

또한 차량이 주차하여 기동되지 않는 상태에서는 상기 이그니션스위치 접점(12)이 off되어 헤드램프(10)는 주위의 조도에 관계없이 소등된 상태를 유지하게 된다.In addition, when the vehicle is not parked and started, the ignition switch contact 12 is turned off so that the headlamp 10 remains unlit regardless of ambient illuminance.

그리고, 야간운행시에 운전자가 헤드램프스위치를 on시킨 상태에서는 상기 점등수단(20)의 출력에 의해 제어됨이 없이 헤드램프(10)는 on상태를 유지하게 된다.In the state where the headlamp switch is turned on by the driver at night, the headlamp 10 is kept on without being controlled by the output of the lighting means 20.

이와같이 본 발명은 차량의 주간 운행시에 주위에 조도상황에 따라 적절하게 헤드램프(10)를 점소등하게 되므로써 운전자의 편의를 도모하게 해주는 효과가 있는 것이다.As described above, the present invention has the effect of facilitating the driver's convenience by turning the headlamp 10 on and off according to the illumination condition in the daytime operation of the vehicle.
