Description
본 발명은 차량의 조명 제어방법에 관한 것으로서, 보다 상세하게는 운전자의 눈부심을 방지하여 안전운전에 기여할 수 있도록 한 개선된 차량의 조명 제어방법에 관한 것이다.The present invention relates to a lighting control method of a vehicle, and more particularly, to an improved vehicle lighting control method for contributing to safe driving by preventing a glare of a driver.
리오스탯(RHEOSTAT)이란, 차량 실내에 실내(INTERIOR) 조명들의 밝기 정도를 운전자가 스스로 원하는 밝기의 정도로 조정할 수 있도록 한 장치이다.RHEOSTAT is a device that allows the driver to adjust the brightness level of INTERIOR lighting inside the vehicle to the desired brightness level.
즉, 너무 밝아서 운전에 장애가 되지 않도록 하거나, 너무 어두워서 식별이 잘 되지 않음으로 인한 장애가 되지 않도록 하기 위한 장치이다.That is, it is a device for preventing the obstacle due to too bright or too difficult to identify, or too dark to identify.
예컨대, 클러스터 페시아(CLUSTER FACIA)부의 클러스터는 엘이디(LED)를 사용하고, 센터 페시아(CENTER FACIA)부의 오디오(AUDIO) 클럭(CLOCK) 스위치 등은벌브(BULB)를 사용한다. 이와 같이 현재는 차량의 위치별로 조명원이 틀리게 설치되어 있다.For example, a cluster of the cluster faucet unit uses an LED, and an audio clock switch of the center fascia unit uses a bulb. As such, the lighting source is installed differently according to the position of the vehicle.
그리고 엘이디를 조명원으로 채용한 CLUSTER를 적용한 차종간의 비교를 보면, 리오스탯 감광시 도 1에 도시된 바와 같은 그래프와 같이 엘이디를 조명원으로 사용하는 클러스터와, 벌브를 조명원으로 사용하는 센터 페시아부 모두가 리오스탯의 듀티(Duty)비 입력에 의하여 감광정도가 조정되고 있다.In addition, when comparing the models using CLUSTER that uses LED as a light source, the cluster using LED as a light source and the center fascia using bulb as a light source as shown in the graph shown in FIG. Both parts are controlled by the duty ratio input of the riostat.
그런데, 리오스탯 감광시 엘이디를 조명원으로 사용하는 클러스터와, 벌브를 조명원으로 사용하는 센터 페시아부의 감광정도가 조명원 차이로 인하여 서로 다르다.However, the sensitivity of the cluster using the LED as a light source and the center fascia using the bulb as the light source are different from each other due to the difference of the light source.
즉, 실차에서 리오스탯 조정시 센터 페시아의 벌브에 의한 조명들은 상당히 어두워지게 되더라도, 클러스터는 밝은 상태이다.That is, the cluster remains bright even though the lights by the bulbs in the center fascia become significantly darker when adjusting the riostat in the actual vehicle.
그리고 도 1의 그래프에 도시된 바와 같이, 리오스탯 작동구간 내에서 임의의 전압대를 선택하여 보면 붉은 색으로 표현된 엘이디의 휘도점이 벌브의 휘도점 보다 더 높게 나타난다.As shown in the graph of FIG. 1, when a voltage level is selected within the riostat operating period, the luminance point of the LED represented by red color is higher than that of the bulb.
본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로서, 차량의 각 위치 및 조명원의 종류에 관계없이 동일한 밝기의 조명이 유지될 수 있도록 차량의 조명 제어방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a lighting control method of a vehicle such that lighting of the same brightness can be maintained regardless of each position of the vehicle and the type of lighting source.
도 1은 종래의 기술에 따른 차량의 조명 제어방법에 따라 휘도와 전압과의 관계를 나타내 보인 개략적인 그래프.1 is a schematic graph illustrating a relationship between luminance and voltage according to a lighting control method of a vehicle according to the related art.
도 2는 본 발명에 따른 차량의 조명 제어방법에 따라 휘도와 전압과의 관계를 나타내 보인 개략적인 그래프.Figure 2 is a schematic graph showing the relationship between the luminance and the voltage according to the lighting control method of the vehicle according to the present invention.
상기와 같은 목적을 달성하기 위한 본 발명의 차량의 조명 제어방법은, 리오스탯 감광시, 차량의 실내에서 벌브를 조명원으로 사용하는 벌브조명부는 상기 리오스탯의 듀티비 입력에 의하여 감광정도가 조정되고, 엘이디를 조명원으로 사용하는 엘이디 조명부는, 상기 리오스탯의 듀티비 입력을 차량의 전자장치에 설치된 마이컴에서 받아서 벌브 밝기에 해당되는 전압값으로 다시 재조정하여 엘이디로 전원을 공급하며, 상기 차량의 상기 리오스탯 조정시 상기 벌브조명부의 상기 벌브에 의한 조명들과 동등한 밝기로 상기 엘이디 조명부를 제어토록 하는 것을 그 특징으로 한다.In the lighting control method of the vehicle of the present invention for achieving the above object, the bulb lighting unit using the bulb as a light source in the interior of the vehicle when the riostat dimming, the degree of sensitivity is adjusted by the duty ratio input of the riostat The LED lighting unit using the LED as an illumination source receives the duty ratio input of the riostat from the microcomputer installed in the electronic device of the vehicle and readjusts the voltage value corresponding to the bulb brightness to supply power to the LED. It characterized in that to control the LED lighting unit at the same brightness as the lighting by the bulb of the bulb lighting unit when adjusting the riostat.
이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2에는 본 발명에 따른 차량의 조명 제어방법이 적용되어 나타낸 그래프가 도시되어 있다.2 is a graph showing a method of controlling the lighting of a vehicle according to the present invention.
본 발명에 따른 차량의 조명 제어방법은, 도 2에 도시된 바와 같이 리오스탯 감광시, 차량의 실내에서 벌브를 조명원으로 사용하는 벌브조명부는 리오스탯의 듀티비 입력에 의하여 감광정도가 조정되고, 엘이디를 조명원으로 사용하는 엘이디 조명부는 리오스탯의 듀티비 입력을 차량의 전자장치에 설치된 마이컴(μ-COM)에서 받아서 벌브 밝기에 해당되는 전압값으로 다시 재조정하여 엘이디로 전원을 공급하며, 차량의 리오스탯 조정시 상기 벌브조명부의 벌브에 의한 조명들과 동등한 밝기로 엘이디 조명부를 제어토록 하여 이루어진다.In the lighting control method of the vehicle according to the present invention, as shown in Figure 2, when the riostat sensitization, the bulb lighting unit using the bulb as an illumination source in the interior of the vehicle is adjusted by the duty ratio input of the riostat The LED lighting unit, which uses the LED as a light source, receives the duty ratio input of the riostat from the microcomputer (μ-COM) installed in the electronic device of the vehicle and readjusts the voltage value corresponding to the bulb brightness to supply power to the LED. When adjusting the vehicle riostat, the LED lighting unit is controlled to have the same brightness as those of the bulbs of the bulb lighting unit.
그리고 도 2에 도시된 그래프와 같이, 상기 엘이디 조명부의 엘이디의 밝기 변화를 리오스탯 작동구간의 절대값을 가진 2개의 1차 방정식으로 출력값이 나오도록 상기 마이컴의 알고리즘을 프로그램하여 벌브조명부의 벌브의 휘도치에 근접시키도록 한다.And, as shown in the graph shown in Figure 2, by programming the microcomputer's algorithm so that the output value of the brightness change of the LED of the LED lighting unit to the two first equation having the absolute value of the riostat operating interval of the bulb of the bulb lighting unit Close to the luminance value.
한편, 상기 벌브조명부는 차량의 실내에서 오디오, 클럭, 및 각 스위치류 등이 장착된 센터 페시아부에 적용되고, 상기 엘이디조명부는 차량의 클러스터부에 적용된다.On the other hand, the bulb lighting unit is applied to the center fascia unit equipped with audio, clock, and each switch in the vehicle interior, the LED lighting unit is applied to the cluster portion of the vehicle.
상술한 바와 같이, 본 발명에 따른 차량의 조명 제어방법은, 차량 실내에 실내 조명들의 밝기 정도를 엘이디 또는 벌브의 조명원의 차이에 관계없이 부품들간에 동등하게 변화시키게 된다.As described above, the lighting control method of the vehicle according to the present invention, the degree of brightness of the interior lights in the vehicle interior is equally changed between the components regardless of the difference in the illumination source of the LED or bulb.
상술한 바와 같이 본 발명에 따른 차량의 조명 제어방법은 다음과 같은 효과를 갖는다.As described above, the vehicle lighting control method according to the present invention has the following effects.
차량 실내의 위치나 조명원에 관계없이 동일한 조명 밝기를 유지할 수 있음으로, 차량의 상품성을 향상시키고, 운전자의 눈부심을 방지하여 안전운전에 기여할 수 있다.Since the same illumination brightness can be maintained regardless of the location or lighting source of the vehicle interior, it is possible to improve the merchandise of the vehicle and prevent the glare of the driver to contribute to safe driving.
본 발명은 도면에 도시된 일 실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 당해 기술 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 실시예가 가능하다는 점을 이해할 것이다. 따라서 본 발명의 진정한 보호 범위는 첨부된 특허청구범위에 의해서만 정해져야 할 것이다.Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.
