Description
본 발명은 헤드램프 밝기 및 상·하향등 자동조절장치에 관한 것으로서, 보다 상세하게는 차량을 운행과정에서 각각의 감지센서에 감지되는 신호의 조건에 따라 헤드램프 밝기 및 상·하향등을 자동적으로 조절하도록 한 자동조절장치에 관한 것이다.The present invention relates to an automatic adjustment device for the head lamp brightness and the up and down lights, and more particularly, to automatically adjust the head lamp brightness and the up and down lights according to the condition of the signal detected by each sensor during the vehicle driving process. It relates to an automatic control device for adjusting.
일반적으로 헤드램프는 두 개의 필라멘트가 있으며, 하나는 먼 곳을 비추는 하이비임(High beam)의 역할을 하고, 다른 하나는 교행할 때 대향차의 운전자가 현혹되지 않토록 광도를 약하게 하고 동시에 비임을 낮추는 로우비임(Low beam)의 역할을 하게 되어 있다.In general, the headlamp has two filaments, one acting as a high beam that illuminates a distant place, and the other means that the driver of the opposite vehicle weakens the brightness and at the same time does not deceive the driver of the opposite vehicle when crossing. It acts as a low beam to lower.
도 1에는 도시된 바와 같이 헤드램프의 개략적인 구성을 도시한 회로도이다. 도 1을 살펴보면 헤드램프는 차량의 전원공구급수단에 의해 구동되며, 라이트스위치(1), 디머스위치(Dimmer switch:2)등으로 구성되며, 양쪽의 헤드램프은 하이비임과 로우비임별로 병렬로 접속되어 있다.1 is a circuit diagram showing a schematic configuration of a head lamp as shown. 1, the head lamp is driven by the power supply means of the vehicle, and consists of a light switch (1), a dimmer switch (2), and the like, and the head lamps on both sides of the high and low beams are paralleled. Connected.
상기 라이트스위치(1)는 2단계로 작동하게 되어 있으며, 제 1단계는 차량의 미등 및 계기판을 점등시키고, 제 2단계는 헤드램프(3)를 점등시키도록 되어 있다. 상기 라이트스위치(1)를 2단계에 위치시킨 상태에서, 손잡이(Knob)를 움직여 내부의 스위치접점을 섭동하여 전원공급수단과 접속하게 된다. 또, 디머스위치(2)는 라이트의 비임을 바꾸는 스위치로, 운전자가 손으로 손잡이를 전·후로 회동시켜 하이비임과 로우비임으로 작동시키게 되는 것이다.The light switch 1 is operated in two stages, the first stage lights up the tail light and the instrument panel of the vehicle, and the second stage lights up the head lamp 3. In the state where the light switch 1 is positioned in the second stage, the knob Knob is moved to perturb the internal switch contact to be connected to the power supply means. In addition, the dimmer switch 2 is a switch for changing the beam of light, and the driver rotates the handle back and forth by hand to operate the high beam and the low beam.
이와 같이, 차량에 설치되어 전방을 비추는 헤드램프(3)의 조작은 운전자가 차량의 시동을 건 상태에서 라이트스위치(1)의 접점을 섭동하고, 디머스위치(2)를 전·후방향으로 운전자가 주변의 교통상항에 따라 대향된 차량의 운전자의 시야를 방해하지 않토록 상향등과 하향등을 선택적으로 점등시킨다.As described above, the operation of the headlamp 3 installed in the vehicle to illuminate the front causes the contact of the light switch 1 to be disturbed while the driver starts the vehicle, and the dimmer switch 2 is moved forward and backward. The driver selectively turns on the high beam and the low beam so as not to obstruct the driver's view of the opposite vehicle according to the surrounding traffic conditions.
즉, 헤드램프의 조작은 차량을 운행하는 과정에서 주간에 안개등으로 전방시야를 확보하지 못하는 경우에 헤드램프를 점등시켜 전방의 시야를 확보하게 되고, 또 대향된 차선에서 차량의 식별이 용이하게 된다. 그리고, 야간에 전방을 환하게 비추어 전방시야를 확보하는 것으로 헤드램프를 운전자가 주변상황에 따라 상·하향등을 적절하게 조절하여 전방의 시야를 확보하는 것이다.That is, in the operation of the headlamp, when the front view cannot be secured by fog lights during the day of driving the vehicle, the headlamp is turned on to secure the front view, and the vehicle can be easily identified in the opposite lane. . In order to secure the front view by illuminating the front at night, the driver may adjust the headlights appropriately according to the surrounding conditions to secure the front view.
그러나, 이와 같은 헤드램프의 상·하향등 조작은 운전자가 차량을 운행과정에서, 야간에 헤드램프를 구동시킨 상태로 교행할 때 대향차량의 운전자의 시야를 방해하는 문제점을 가지며, 또 헤드램프의 비임에 의해 사람의 시야가 현혹되지 않토록 운전자가 상·하향등을 선택적으로 조절해야 하는 되는 불편한 문제점을 갖게 된다.However, such headlight up and down operation has a problem that the driver's view of the opposite vehicle is obstructed when the driver crosses the vehicle while driving the vehicle at night while driving. There is an uncomfortable problem that the driver must selectively adjust the up, down, etc. so that the vision of the person is not dazzled by the beam.
이에 본 발명은 상기와 같은 문제점을 고려하여 안출된 것으로서, 그 목적은 차량을 운행과정에서 각각의 감지센서에 감지되는 신호의 조건에 따라 헤드램프 밝기 및 상·하향등을 자동적으로 조절하도록 한 자동조절장치를 제공함에 있다.Accordingly, the present invention has been made in view of the above problems, the object of which is to automatically adjust the headlamp brightness and up and down according to the condition of the signal detected by each sensor in the course of driving the automatic In providing an adjusting device.
이러한, 본 발명의 목적은 차량의 차속을 감지하는 차속감지센서와, 상기 차량의 주변밝기를 감지하는 광센서와, 대향차량의 거리를 감지하는 거리감지센서와, 상기 차속감지센서와 광센서와 거리감지센서에서 출력된 신호에 따라 감지조건을 판별하여 판별된 신호를 출력하는 마이컴과 상기 마이컴에서 출력된 신호에 따라 헤드램프의 밝기를 조절하는 헤드램프밝기조절부와, 상기 헤드램프밝기조절부로부터 출력된 신호에 의해 헤드램프를 점등시키는 헤드램프구동부로 구성함으로서 달성될 수 있다.The object of the present invention is a vehicle speed sensor for detecting the vehicle speed of the vehicle, an optical sensor for detecting the ambient brightness of the vehicle, a distance sensor for detecting the distance of the opposite vehicle, the vehicle speed sensor and the optical sensor and A microcomputer for outputting a signal determined by determining a sensing condition according to a signal output from a distance sensor, a headlamp brightness controller for controlling a brightness of a headlamp according to the signal output from the microcomputer, and the headlamp brightness controller It can be achieved by configuring the head lamp driving unit for lighting the head lamp by the signal output from the.

In addition, the signal detected by the optical sensor 20 for detecting the ambient brightness of the vehicle is input to the microcomputer 40. Then, the distance sensor 30 for maintaining a constant distance with the opposite vehicle, by detecting the return time value of the radio wave is calculated by sending the radio wave forward reflected by the vehicle to calculate the distance by the detected signal The calculated distance signal is input to the microcomputer 40.
상기 마이컴(40)은 차속감지센서(10)와 광센서(20)와 거리감지센서(30)에서 각각 감지되는 신호에 따라 헤드램프의 상·하향등 변환 제어신호와, 헤드램프밝기를 조절하는 신호가 출력된다. 마이컴(40)에서 출력된 신호에 의해 헤드램프구동부(60)는 상향등 또는 하향등을 점등시키고, 헤드램프밝기조절신호는 차량의 전원공급수단의 전압을 가변저항으로 전압량을 조절하여 헤드램프의 밝기를 자동조절되며, 상기 헤드램프밝기조절부(50)에서 출력된 신호에 의해 헤드램프의 밝기가 자동조절되어 헤드램프구동부(70)를 통하여 점등시킨다.The microcomputer 40 adjusts the up / down light conversion control signal of the headlamp and the headlamp brightness according to signals detected by the vehicle speed sensor 10, the light sensor 20, and the distance sensor 30, respectively. The signal is output. According to the signal output from the microcomputer 40, the headlamp driving unit 60 lights up the uplight or the downlight, and the headlamp brightness control signal controls the voltage of the headlamp by adjusting the voltage of the vehicle power supply means with a variable resistor.
