이하, 본 고안을 첨부한 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 의한 자동차의 전조등/안개등 자동 제어장치 구성도이다.도시된 바와 같이, 차량 주변의 조도를 검출하는 조도센서(1)와; 감지 영역내의 일측에서 광을 투사하고 그 감지 영역 타측에서 광을 수광하여 눈 또는 비의 양을 감지하는 포토인터럽트부(2)와; 상기 조도센서(1) 및 포토인터럽트부(2)에서 각각 출력되는 신호로 차량 주변의 조도 및 눈/비의 양을 판단하고 그 판단 결과 주변 조도가 낮거나 눈 또는 비의 양의 많은경우 자동으로 안개등 및 전조등 점등신호를 발생하는 마이컴(3)과; 상기 마이컴(3)에서 출력되는 안개등 점등신호에 따라 좌,우측 안개등을 점등시키는 안개등 릴레이(4)와; 상기 안개등 릴레이(4)를 통해 공급되는 전원으로 점등되는 좌,우측 안개등(5)(6)과; 상기 마이컴(3)에서 출력되는 전조등 점등신호에 따라 좌,우측 전조등을 점등시키는 전조등 릴레이(7)와; 상기 전조등 릴레이(7)로 부터 공급되는 전원으로 점등되는 좌,우측 전조등(8)(9)으로 구성 되었다.1 is a block diagram of an automatic control device for a headlight / fog light of a vehicle according to the present invention. As shown, an illuminance sensor 1 for detecting illuminance around a vehicle; A photo interrupter (2) for projecting light from one side of the sensing area and receiving light from the other side of the sensing area to sense the amount of snow or rain; The light output from the light sensor 1 and the photo interrupter 2 are used to determine the amount of illuminance and snow / rain in the vicinity of the vehicle. A microcomputer 3 for generating a fog light and a headlamp lighting signal; A fog light relay 4 for lighting the left and right fog lights according to the fog light lighting signal output from the microcomputer 3; Left and right fog lights (5) and (6) which are turned on by the power supplied through the fog light relay (4); A headlight relay 7 for lighting the left and right headlights according to the headlight lighting signal output from the microcomputer 3; It consists of left and right headlights (8) and (9) which are turned on by the power supplied from the headlight relay (7).

상기에서, 포토인터럽트부(2)는 감지 영역의 일측에 구비되어 광을 투사하는 발광부(2a)와, 상기 감지 영역의 타측에 구비되어 발광부(2a)에서 투사되는 광을 수광하여 전기적인 신호로 변환하는 수광부(2b)로 구성 되었다.In the above, the photointerrupter 2 is provided on one side of the sensing area to project light, and is provided on the other side of the sensing area to receive light projected from the light emitting part 2a to be electrically connected. It consists of the light receiving part 2b which converts into a signal.

이와 같이 구성된 본 고안에 의한 전조등/안개등 자동 제어장치의 작용을 설명하면 다음과 같다.Referring to the operation of the headlight / fog light automatic control device according to the present invention configured as described as follows.

먼저, 이그니션이 온(ON)되면, 마이컴(3)은 자동으로 전조등 및 안개등을 제어하기 위해 조도센서(1)의 출력값과 포토인터럽트부 (2)의 출력값을 읽어들인다.First, when the ignition is ON, the microcomputer 3 automatically reads the output value of the illuminance sensor 1 and the output value of the photo interrupter 2 to control the headlamp and the fog lamp.

즉, 조도 센서(1)는 차량 주변의 조도를 감지하여 마이컴(3)의 아날로그/디지탈 포트를 통해 마이컴(3)에 전달하게 되고, 포토 인터럽트부(2)는 도 2 와 같이 발광부(2a)로 감지 영역내로 광을 투사하고, 수광부(2b)로 그 광을 수광하여 전기적인 신호로 변환을 하게된다.That is, the illuminance sensor 1 detects illuminance around the vehicle and transmits the illuminance to the microcomputer 3 through the analog / digital port of the microcomputer 3, and the photo interrupter 2 emits the light emitting unit 2a as shown in FIG. 2. ) Projects the light into the sensing area, receives the light with the light receiving portion 2b, and converts the light into an electrical signal.

이때, 눈이나 비등이 오지 않는 경우에는 발광부(2a)에서 투사된 광이 그대로 수광부(2b)에 수광이 되며, 이와는 달리 눈이나 비등이 많이 오게되면 발광부(2a)에서 투사된 광이 눈이나 비등에 의해 반사되므로 실제적으로 수광부(2b)로 수광되는 광은 거의 없다.At this time, when the snow or boiling does not come, the light projected from the light emitting unit 2a is received by the light receiving unit 2b as it is, otherwise, if a lot of snow or boiling comes, the light projected from the light emitting unit 2a is eye Since it is reflected by light or boiling, practically no light is received by the light receiving portion 2b.

이러한 원리에 의해 수광부(2b)는 광의 수광 여부에 따른 신호를 발생하여 상기한 마이컴(3)에 전달하게되고, 마이컴(3)은 상기한 조도 센서(1)의 출력신호와 포토인터럽트부(2)의 출력신호를 검색하여 안개등 및 전조등의 점등 여부를 결정한다.By this principle, the light receiving unit 2b generates a signal according to whether light is received or not and transmits the signal to the microcomputer 3, and the microcomputer 3 outputs the photo signal of the illuminance sensor 1 and the photo interrupting unit 2. Search for the output signal to determine whether the fog light and the headlight are lit.

즉, 차량 주변의 조도가 낮거나 눈 또는 비등이 많이 오는 것으로 판단되면 자동으로 전조등 및 안개등을 점등시키기 위한 점등신호를 발생하게 되고, 그 발생되는 점등신호에 의해 안개등 릴레이(4)는 구동하여 좌측 및 우측 안개등(5)(6)에 점등 전원을 공급해준다.That is, when it is determined that the ambient light around the vehicle is low or a lot of snow or rain comes, a lighting signal for automatically turning on the headlights and fog lights is generated, and the fog light relay 4 is driven to the left by the generated lighting signal. And a lighting power supply to the right fog light (5) (6).

이에 따라 좌,우측 안개등(5)(6)은 공급되는 전원으로 점등을 하게된다.Accordingly, the left and right fog lights 5 and 6 are turned on by the power supplied.

아울러, 발생되는 점등신호에 의해 전조등 릴레이(7)는 구동하여 좌측 및 우측 전조등(8)(9)에 점등 전원을 공급해주게되며, 이에 따라 좌,우측 전조등(8)(9)은 공급되는 전원으로 점등을 하게되는 것이다.In addition, the headlight relay 7 is driven by the lighting signal generated to supply lighting power to the left and right headlights 8 and 9, and thus the left and right headlights 8 and 9 are supplied with power. It turns on.

이상에서와 같이 본 고안은 차량 주변의 조도와 눈 또는 비의 양을 검출하여 자동으로 안개등 및 전조등을 제어 함으로써 기존과 같이 수동조작에 따른 불편함을 해소시킬 수 있는 효과가 있다.As described above, the present invention detects the amount of illuminance and snow or rain around the vehicle and automatically controls the fog light and the headlight, thereby eliminating the inconvenience caused by manual operation.

또한, 자동으로 안개등 및 전조등을 점등시킴으로써 운전자의 운전 집중을 도모하므로써 안전 운전을 도모하는 효과도 있다.In addition, by automatically turning on the fog light and headlights, the driver's driving concentration can be achieved, thereby promoting safe driving.

본 고안은 자동차의 전조등/안개등 자동 제어에 관한 것으로, 특히 주간에 눈,비가 많이 내릴때에 자동으로 전조등(헤드램프)이나 안개등을 자동으로 점등시켜 운전자의 수동 조작에 따르는 불편함을 해소시키도록 한 자동차의 전조등/안개등 자동 제어장치에 관한 것이다.The present invention relates to the automatic control of the headlight / fog light of the automobile, and in particular, in order to alleviate the inconvenience caused by the manual operation of the driver by automatically lighting the headlight or the headlight automatically when it rains or rains a lot during the day. A vehicle headlight / fog light automatic control device.
