Abstract

PURPOSE: An automatic control method for an interior lighting is provided to set a reference value of luminosity by drivers using a control knob, to decide consecutively signals detecting the luminosity of surroundings by an illumination sensor, and to adjust the luminosity to the reference value by drivers' setting compared with an illumination setting value. CONSTITUTION: An interior lighting automatically controlling method includes a step of deciding if power is fed to the interior lighting. A reference control duty is set as drivers adjust the optimum luminosity of the interior lighting by operating a control knob. An illumination sensor detects the luminosity of surroundings around the interior lighting. A compensation control duty is settled to compare a detected value of the illumination sensor with a reference illumination value of the reference control duty. A current signal lighten the lighting luminosity up to the reference illumination value on the compensation control duty is transmitted when the detected illumination value of the illumination sensor is smaller than the reference illumination value. On the contrary, the current signal darken the lighting luminosity down to the reference illumination value on the compensation control duty is delivered when the detected illumination value of the illumination sensor is bigger than the reference illumination value.

이와 같은 단계로 이루어진 본 발명 따른 차량의 실내조명등 자동 조절 방법을 첨부한 도면을 참조로 더욱 상세하게 설명하면 다음과 같다.When described in more detail with reference to the accompanying drawings, the method for automatically adjusting the interior lighting of the vehicle according to the present invention made as described above as follows.

첨부한 도 1은 본 발명에 따른 차량의 실내조명등 자동 조절 방법을 나타내는 회로도로서, 입력부와 제어부와 출력부로 나누어진다.1 is a circuit diagram illustrating a method for automatically adjusting interior lighting of a vehicle according to the present invention, which is divided into an input unit, a control unit, and an output unit.

상기 입력부는 실내조명등에 인가되는 전원과, 조도센서, 그리고 조정노브로 구성되어 있다.The input unit is composed of a power applied to the indoor lighting, an illuminance sensor, and an adjusting knob.

따라서, 실내조명등에 전원이 인가되는 상태에서 운전자가 조정노브를 조작하여 실내조명등의 기준밝기를 가장 적절하다고 판단되는 수준으로 조정하게 된다.Therefore, the driver operates the adjustment knob while the power is applied to the indoor lighting to adjust the reference brightness of the indoor lighting to the level determined to be most appropriate.

또한, 조도센서가 실내조명등의 주변밝기 감지를 시작하게 된다.In addition, the illuminance sensor starts to detect the ambient brightness such as indoor lighting.

상기 제어부는 상기 조도센서의 감지값과 상기 조정노브의 기준밝기값을 비교 연산하여, 실내조명등의 조도를 기준 밝기값으로 가감 연산하여 출력부를 통하여 출력하는 곳으로서, 이미 상기 조정노브의 기준밝기값은 입력된 상태가 된다.The control unit compares the detected value of the illuminance sensor with the reference brightness value of the adjusting knob, and calculates and outputs the illuminance of the indoor lighting, etc. to a reference brightness value, and outputs it through the output unit. Becomes input state.

여기서, 첨부한 2를 참조로 본 발명에 따른 차량의 실내조명등 자동 조절 방법을 순서대로 설명하면 다음과 같다.Here, with reference to the accompanying 2 will be described in the order of automatically adjusting the interior lighting of the vehicle according to the invention as follows.

먼저, 실내조명등으로 전원이 인가되는 상태인지를 판단하는 단계로서, 테일 스위치(Tail switch)가 온인지를 판단한다.First, as a step of determining whether power is applied by indoor lighting, it is determined whether a tail switch is on.

상기 테일 스위치가 온이면, 운전자는 실내조명등의 조정 노브를 조작하여, 실내조명등의 밝기를 운전자에게 가장 적절하다고 판단되는 수준까지 조정하게 되고, 이때 조정된 밝기는 기준조도값이 되어, 제어부로 입력되어진다.When the tail switch is turned on, the driver operates an adjustment knob of an indoor lighting lamp to adjust the brightness of the indoor lighting lamp to a level determined to be most suitable for the driver, and the adjusted brightness is a reference illuminance value and is input to the controller. It is done.

즉, 상기 조정노브의 조작에 따라 연산부에는 기본제어 듀티가 결정(듀티기준)된다.That is, the basic control duty is determined (duty reference ) in the calculation unit in accordance with the operation of the adjustment knob.

이때, 상기 조도센서에서 실내조명등의 주위 밝기를 계속 감지하는 단계가 진행되는 바, 실내조명등 주변의 가변되는 조도를 계속 감지하여 제어부로 그 감지신호를 보내게 된다.At this time, the step of continuously detecting the ambient brightness of the indoor light in the light sensor is progressed, it continues to detect the variable illumination around the indoor light and sends the detection signal to the control unit.

다음으로, 상기 연산부에서 상기 조도센서의 감지값을 수신하여 기준 제어 듀티의 기준조도값과 비교한 후, 보상제어 듀티를 결정하는 단계가 진행된다.Next, the operation unit receives the detected value of the illuminance sensor, compares it with the reference illuminance value of the reference control duty, and then determines the compensation control duty.

따라서, 첨부한 도 3a,3b,3c에 도시한 바와 같이 기준조도값으로 실내조명등의 밝기가 자동 조절되어진다.Accordingly, as shown in FIGS. 3A, 3B, and 3C, the brightness of the indoor light is automatically adjusted to the reference illuminance value.

즉, 상기 조도센서의 감지조도값이 기준조도값보다 작으면, 상기 연산부에서결정된 보상제어 듀티에 의하여 조명등의 밝기를 기준조도값까지 밝아지게 하는 전류신호를 출력부를 통하여 상기 실내조명등으로 보내게 됨으로써, 실내조명등이 기준조도값을 갖는 밝기로 점등된다.That is, when the detected illuminance value of the illuminance sensor is smaller than the reference illuminance value, a current signal for illuminating the brightness of the lamp to the reference illuminance value is sent to the indoor illuminator through the output unit by the compensation control duty determined by the calculating unit. , The indoor lighting is turned on with the brightness having the standard illuminance value.

또한, 상기 조도센서의 감지조도값이 기준조도값보다 크면, 상기 연산부에서 결정된 보상제어 듀티에 의하여 조명등의 밝기를 기준조도값까지 어두워지도록 감소된 전류신호를 보내어, 결국 실내조명등이 기준조도값으로 발광된다.In addition, if the detected illuminance value of the illuminance sensor is greater than the reference illuminance value, the current signal is reduced to darken the brightness of the lamp to the reference illuminance value by the compensation control duty determined by the calculating unit. Light emission.

이상에서 본 바와 같이, 본 발명에 따른 차량의 실내조명등 자동 조절 방법에 의하면, 실내조명등의 밝기정도를 운전자가 가장 적절하다고 생각되는 수준으로 미리 입력하여, 실내조명등의 밝기가 항상 일정한 수준으로 자동 조절되도록 함으로써, 운전자의 시야에 맞는 수준으로 실내밝기가 조절되어 편의성과 안정성을 제공하는 잇점이 있다.As described above, according to the method for automatically adjusting the interior lighting of the vehicle according to the present invention, the brightness of the interior lighting is input in advance to the level that the driver thinks most appropriate, and the brightness of the interior lighting is always automatically adjusted to a constant level. By doing so, the room brightness is adjusted to a level suitable for the driver's field of view to provide convenience and stability.
