Description
본 고안은 자동차의 등화회로에 관한 것으로, 더욱 상세하게는 조도센서를 통해 운행장소의 조도를 감지하여 스몰등이나 전조등의 밝기를 자동으로 조절하는 자동차의 조도순응식 등화회로에 관한 것이다.The present invention relates to a lighting circuit of a vehicle, and more particularly, to an illuminance-compliant lighting circuit of the vehicle to automatically sense the brightness of the small light or the headlight by detecting the illuminance of the driving place through the light sensor.
일반적으로 자동차에는 어두운 곳이나 야간에 주행하게 될 때 전방을 밝게 비쳐주어 운전자의 시야를 확보해 줄 수 있도록 된 전조등으로서 헤드램프가 설치되어 있는 바, 주로 운전자가 조작하기 용이한 위치의 조향축에 설치되는 컴비네이션스위치(여기서 컴비네이션스위치라 함은 조명에 관련된 라이트스위치를 말함)를 운전자가 조작함에 따라 차체의 앞쪽에 설치되어 있는 전조등이 점등 또는 소등되도록 되어 있다.In general, a headlamp is installed as a headlight that can illuminate the driver's sight by brightly illuminating the vehicle when driving in a dark place or at night, and is mainly provided on a steering shaft that is easily operated by a driver. As the driver operates the combination switch (here, the combination switch refers to a light switch related to lighting), the headlights installed in front of the vehicle body are turned on or off.
또한 헤드램프는 주로 근거리를 조사하도록 된 하향등과 원거리까지 조사할 수 있는 상향등으로 구성되어 있는데, 상향등은 원거리까지 조사하기 위하여 조사각도가 수직방향으로 좀 더 윗쪽으로 넓게 퍼지도록 이루어져 있다.In addition, the headlamp mainly consists of a low-light to be irradiated at a short distance and a high-light that can be irradiated to a long distance, the upper light is composed so that the irradiation angle to spread farther upward in the vertical direction to irradiate far.
그런데 헤드램프를 작동시킨 상태에서 야간에 운전을 하다가 차량이 교차로등에서 신호대기로 정차를 할 경우 또는 횡단보도등에서 보행자신호의 점등에 의해 일정시간 동안 정차를 하고 있게 될 경우 마주 보고 서있거나 주행하고 있는 상대 차량이나 동일 진행방향의 앞차에 눈부심을 주지 않기 위하여 또는 횡단보도를 보행하고 있는 보행자에게 눈부심을 주어 보행에 불편을 주지 않도록 하기 위한 등의 이유로 헤드램프를 소등시키고 있게 된다.However, when driving at night with the headlamp activated, the vehicle stops with a signal stand at an intersection, or when the vehicle stops for a certain period of time by turning on a pedestrian signal at a pedestrian crossing. The headlamps are turned off for the purpose of not giving a glare to an opponent vehicle or a vehicle in the same traveling direction, or to give a pedestrian walking on a crosswalk so as not to cause inconvenience to walking.
또한 주행중에 마주오는 차량이 없는 경우 상향등을 점등시켜 원거리까지 시야를 확보하면서 주행하다가 마주오는 차를 발견하게 되면 다시 하향등으로 바꾸어 주행하므로써 마주오는 차량의 운전자에 대한 시야확보에 지장을 주지 않으려 하고 있다.In addition, if there is no vehicle coming while driving, the driver lights up the high light to secure the view to a long distance, and when it finds an oncoming car, it switches back to the lower light so that it does not interfere with securing the visibility of the driver of the oncoming vehicle. have.
그러나 종래의 자동차에 있어서는 헤드램프의 상하향등의 점등 및 소등은 운전자의 컴비네이션스위치 조작에 따라 이루어지도록 되어 있었기 때문에 주행도중에 일일이 운전자가 주행환경(조도)이 바뀔때마다 컴비네이션스위치를 조작하여 전조등을 점등 또는 소등시키게 되는 동작을 반복하게 되면 운전자가 매우 불편함을 느끼게 될 뿐만 아니라 경우에 따라서는 마주오는 차량이 있는데도 불구하고 상향등을 켠채 그대로 주행하게 되면 상대방 차량의 운전자에게 불쾌감을 주게 될 뿐만 아니라 안전운전에도 지장을 주게 되는 문제점이 발생된다.However, in a conventional car, the headlamps are turned on and off according to the driver's combination switch operation. Therefore, each time the driver changes the driving environment (illumination), the headlight is turned on. Or if you repeat the operation to turn off, the driver will not only feel very uncomfortable, but in some cases, even if there is an oncoming vehicle, driving with the upper lights on will not only discomfort the driver of the other vehicle, but also drive safely. Even the problem that causes trouble.
본 고안은 상기한 문제점을 개선하기 위하여 안출된 것으로, 야간 운전시 운전자가 조도 즉 주행도로상의 빛의 밝기에 따라 헤드램프를 점등 또는 소등시키지 않아도 되도록 컴비네이션스위치를 통해 자동 조도 모우드를 선택하면 주행환경의 조도에 따라 예컨데 초저녁과 같이 어두워지기 시작할 때에는 차폭등이나 테일램프 또는 차량번호판램프 등을 점등시키고 일몰이후 어두울 때에는 헤드램프를 점등시키면서 또다시 주변의 어두움 정도에 따라 헤드램프의 밝기를 가변시켜 조도에 따라 헤드램프 및 스몰드의 점소등과 함께 밝기를 가변시킬 수 있도록 된 자동차의 조도순응식 등화회로를 제공하고자 함에 고안의 목적이 있다.The present invention was devised to improve the above problems, and when the driver selects the auto illuminance mode through the combination switch so that the driver does not have to turn on or off the headlamp according to the illuminance, that is, the brightness of the light on the road. When it starts to get dark like early evening, turn on the headlight, tail lamp or license plate lamp, and turn on the head lamp when it is dark after sunset and change the brightness of the head lamp according to the darkness of surroundings. The purpose of the present invention is to provide an illuminance compliant equalization circuit of a vehicle that can vary the brightness with headlights and small lights.
상기한 목적을 실현하기 위한 본 고안은 컴비네이션스위치에 램프자동점등 단자를 추가로 구비하고, 차체에는 차량외측의 조도를 감지하여 조도레벨을 판단할 수 있는 수단을 구비하며, 스몰등(차폭등, 테일램프, 차량번호판램프등)과 헤드램프에는 상기 컴비네이션스위치측과 조도레벨 감지수단측에 선택적으로 접소될 수 있는 스위칭수단을 접속시킴으로써 운전자가 기존과 같이 수조작으로 램프류를 구동하거나 또는 자동 모우드를 선택한 경우에는 조도레벨 감지수단에 의해 접속되는 스위칭소자에 따라 램프류가 자동으로 점등될 수 있도록 이루어진 것이다.The present invention for realizing the above object is further provided with a lamp automatic lighting terminal in the combination switch, the vehicle body is provided with a means for determining the illumination level by detecting the illumination from the outside of the vehicle, and the small light (vehicle lamp, Tail lamps, license plate lamps, etc.) and head lamps are connected to the combination switch side and illuminance level sensing means side by means of a selective switching means. In the case of selection, the lamps are automatically turned on in accordance with the switching elements connected by the illuminance level detecting means.

Is connected to the control unit 20, and the output coil of the control unit 20 is connected to the drive coils of the relays 22 and 24, and at the input end, an illuminance sensor for sensing and inputting illuminance outside the vehicle ( 30) analog / digital conversion It is connected to a 28-mediated.
제1도는 본 고안에 따른 자동차 등화회로의 구성도를 도시한 것이다.1 is a block diagram of an automobile equalization circuit according to the present invention.
컴비네이션스위치(12)는 통상 도면에 OFF로 표시된 오프단자와 TNS로 표시된 스몰등점등단자, 그리고 헤드램프 점등단자로 이루어져 TNS단자는 스몰등(14; 차폭등, 테일램프, 차량번호판램프, 오디오램프 등을 종합적으로 일컫는 용어로 표시함)에 접속되어 있고 헤드램프 점등단자는 헤드램프(16)에 접속되어 있는 것인데, 본 고안을 위해 자동 모우드단자가 추가로 구비되어 있는 것이다.The combination switch 12 is usually composed of an OFF terminal marked OFF in the drawing, a small lighting terminal marked TNS, and a head lamp lighting terminal, and the TNS terminal is a small lamp 14 (vehicle lamp, tail lamp, license plate lamp, audio lamp). And a head lamp lighting terminal are connected to the head lamp 16, and an automatic mode terminal is additionally provided for the present invention.
먼저 컴비네이션스위치(12)가 TNS 단자나 헤드램프 점등단자에 접속되도록 조작되어 있을 때에는 스몰등(14)이나 헤드램프(16)에 자동차 배터리(10)의 전원이 직접 인가되어 해당 램프가 점등되고, OFF 에 접속되어 있을 때에는 배터리(10) 전원공급이 차단되어 소등된다.First, when the combination switch 12 is operated to be connected to the TNS terminal or the headlamp lighting terminal, the power of the vehicle battery 10 is directly applied to the small lamp 14 or the headlamp 16, and the corresponding lamp is turned on. When connected to OFF, the power supply of the battery 10 is cut off and turned off.
그러나 컴비네이션스위치(12)가 자동 모우드단자에 접속된 경우에는 릴레이(18)의 릴레이코일에 배터리(10)의 전원이 인가되고 그에 따라 릴레이(18)의 릴레이스위치가 온상태로 접속되어 릴레이(22)(24)의 릴레이스위치 즉 스몰등(14)과 헤드램츠(16)가 점등가능한 상태로 된다. 이때 릴레이(22)(24)의 릴레이스위치는 오프되어있는 상태이며 후술되는 바와같이 조도에 따라 콘트롤유니트(20)에서 출력되는 제어신호에 의해 온오프된다.However, when the combination switch 12 is connected to the automatic mode terminal, the power of the battery 10 is applied to the relay coil of the relay 18, and accordingly, the relay switch of the relay 18 is connected to the on state so that the relay 22 The relay switch of the 24), i.e., the small lamp 14 and the headlamps 16 are turned on. At this time, the relay switches of the relays 22 and 24 are in an off state and are turned on and off by a control signal output from the control unit 20 according to illuminance as described below.
즉 예시도면 제2도에 도시된 바와같이 자동 모우드가 선택된 경우에는 조도센서(30)에 의해 감지되는 차량주변의 조도신호가 아날로그/디지탈변환기(28)를 거쳐 콘트롤유니트(20)로 입력되고, 그에 따라 콘트롤유니트(20)는 조도의 레벨을 감지한 후 사전에 기준레벨로 설정되어 있는 조도레벨과 비교하여 현재의 조도가 초저녁에 해당되는지 대낮에 해당되는지 또는 아주 어두운 밤에 해당되는지를 판단한다.In other words, when the automatic mode is selected as shown in FIG. 2, an illuminance signal around the vehicle sensed by the illuminance sensor 30 is input to the control unit 20 via the analog / digital converter 28. Accordingly, the control unit 20 detects the level of illuminance and compares it with the illuminance level previously set as a reference level to determine whether the current illuminance corresponds to early evening, daylight or very dark night. .
그 결과 주변의 조도가 초저녁에 해당된다고 판단되면 릴레이(22)에 제어신호를 송출하여 릴레이(22)의 릴레이코일을 구동시켜 그 스위치를 온상태로 접속시킨다. 그에 따라 배터리(10)의 전원이 스몰등(14)에 인가되어 스몰등(14)이 점등된다.As a result, when it is determined that the ambient illuminance corresponds to the early evening, the control signal is sent to the relay 22 to drive the relay coil of the relay 22 to connect the switch to the on state. As a result, power of the battery 10 is applied to the small lamp 14 so that the small lamp 14 is turned on.
이와는 달리 주변의 조도가 아주 어둡다고 판단되면 릴레이(24)에 제어신호를 송출하여 릴레이(24)의 릴레이코일을 구동시켜 그 스위치를 온상태로 접속시킨다. 그에 따라 배터리(10)의 전원이 볼륨(26)를 통해 헤드램프(16)에 인가되어 헤드램프(16)가 점등된다. 이때 볼륨(26)의 가변저항값은 콘트롤유니트(20)에 의해 출력되는 제어신호에 의해 조정되며 콘트롤유니트(20)는 조도센서(30)로부터 입력되는 조도신호에 따라 볼륨(26)의 저항값을 조정하게 된다. 이러한 볼륨(26)은 디지털 볼륨으로서 콘트롤유니트(20)에 의해 출력되는 제어신호에 따라 그 저항값이 조정될 수 있도록 된 것이다.On the other hand, when it is determined that the ambient illuminance is very dark, the control signal is sent to the relay 24 to drive the relay coil of the relay 24 to connect the switch to the on state. Accordingly, the power of the battery 10 is applied to the headlamp 16 through the volume 26 to light the headlamp 16. At this time, the variable resistance value of the volume 26 is adjusted by the control signal output by the control unit 20 and the control unit 20 is the resistance value of the volume 26 in accordance with the illuminance signal input from the illuminance sensor 30. Will be adjusted. This volume 26 is a digital volume so that the resistance value can be adjusted in accordance with the control signal output by the control unit 20.
따라서 자동 모우드시 컴비네이션스위치(12)를 조작하여 헤드램프(16)를 점등시키게 되면 차량 주변 특히 조도센서(30)를 차량의 전방에 설치한 경우에는 전방의 조도에 따라 헤드램프(16)의 밝기가 자동으로 조절된다.Accordingly, when the headlamp 16 is turned on by operating the combination switch 12 in the automatic mode, the brightness of the headlamp 16 according to the illuminance of the front side, especially when the ambient light sensor 30 is installed in front of the vehicle. Is adjusted automatically.
상기한 바와같이 본 고안은 차량의 운행중 등화회로의 점등제어에 있어 운전자가 일일이 컴비네이션스위치를 조작하지 않아도 조도센서의 작동에 따라 자동으로 스몰등이나 헤드램프가 점,소등되고, 특히 헤드램프의 경우 그 밝기가 조절되므로 운전자의 편리를 도모할 수 있는 장점이 있다.As described above, the present invention is designed to control the lighting of the light circuit while the vehicle is running. Even though the driver does not operate the combination switch, the small light or the head lamp is automatically turned on or off according to the operation of the illumination sensor. Since the brightness is adjusted, there is an advantage to facilitate the driver's convenience.
