And a third step of selectively turning on the tail light and the headlamp when the brightness is less than a predetermined value as a result of the determination of the second step.
이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 따른 차량의 미등 및 전조등 자동 점등 장치는 도 1 에 도시된 바와 같이, 차량 외부의 밝기를 감지하고, 그 감지 결과에 따른 크기의 센싱 신호가 생성 출력되는 센서부(30)와, 상기 센서부(30)에서 출력되는 센싱 신호를 전달받아 차량 외부의 밝기를 판단하고, 차량의 미등(10) 및 전조등(20)의 점등 여부를 판단하는 마이컴(40)과, 상기 마이컴(40)의 판단 결과에 따라 상기 차량의 미등(10) 및 전조등(20)을 선택적으로 점등시키는 다수개의 스위치부(50, 60)를 포함하여 구성된다.As shown in FIG. 1, the apparatus for automatically lighting a taillight and a headlight of a vehicle according to the present invention detects the brightness of the outside of the vehicle and generates and outputs a sensing signal having a size corresponding to the detection result. The microcomputer 40 determines the brightness of the outside of the vehicle by receiving the sensing signal output from the sensor unit 30, and determines whether the tail light 10 and the headlamp 20 of the vehicle are turned on, and the microcomputer 40 of the microcomputer 40. And a plurality of switch units 50 and 60 for selectively lighting the tail light 10 and the headlamp 20 of the vehicle according to the determination result.
여기서, 상기 센서부(30)는 포토 다이오드(Photo Diode)가 사용되는데, 이러한 포토 다이오드는 p-n 접합 또는 정류성을 나타내는 금속과 반도체와의 접촉의 역방향 전류가 빛의 조사에 의한 광기전력효과로 증가하는 것을 이용한 것으로써, p영역에 음, n영역에 양의 전압을 가한 상태에서 임의의 파장을 가지는 빛을 조사하면, 저항이 높은 p-n 접합에서 전류가 발생되는 것이다.Here, a photo diode is used as the sensor unit 30. In this photo diode, a reverse current of a contact between a metal exhibiting a pn junction or rectification and a semiconductor increases due to a photovoltaic effect by irradiation of light. In this case, when light having an arbitrary wavelength is irradiated while a negative voltage is applied to the p region and a positive voltage is applied to the p region, a current is generated at the pn junction having a high resistance.
상기 마이컴(40)은 상기 센서부(30)에서 출력되는 센싱 신호를 전달받아 상기 차량의 미등(10) 및 전조등(20) 여부를 판단하게 되는데, 상기 센싱 신호의 크기가 설정치 미만으로 감소하게 되면, 상기 마이컴(20)은 상기 다수개의 스위치부(50, 60)가 선택적으로 온되도록 하는 제어 신호를 출력시키며, 그에 따라 상기 다수개의 스위치부(50, 60)가 온되어 상기 미등(10) 및 전조등(20)이 선택적으로 점등된다.The microcomputer 40 receives the sensing signal output from the sensor unit 30 to determine whether the tail light 10 and the headlamp 20 of the vehicle are reduced, and when the size of the sensing signal decreases below a set value. The microcomputer 20 outputs a control signal for selectively turning on the plurality of switch units 50 and 60, and accordingly, the plurality of switch units 50 and 60 are turned on so that the taillight 10 and Headlamp 20 is selectively lit.
이때, 상기 다수개의 스위치부(50, 60)는 상기 미등(10)과 연결되는 제 1 스위치부(50)와 상기 전조등(20)과 연결되는 제 2 스위치부(60)로 이루어진다.In this case, the plurality of switch units 50 and 60 may include a first switch unit 50 connected to the tail light 10 and a second switch unit 60 connected to the headlamp 20.
즉, 상기 마이컴(20)은 상기 센싱 신호의 크기가 제 1 설정치 미만으로 감소하게 되면, 상기 미등(10)과 연결되는 제 1 스위치부(50)를 온시키게 되고, 상기 센싱 신호의 크기가 상기 제 1 설정치보다 작은 제 2 설정치 미만으로 감소하게 되면, 상기 전조등(20)과 연결된 제 2 스위치부(60)를 온시키게 되어 결국, 상기 센싱 신호의 크기가 상기 제 2 설정치 미만으로 감소하게 되면, 상기 미등(10) 및 전조등(20)과 연결된 제 1 및 제 2 스위치부(50, 60)가 모두 온되어 미등(10) 및 전조등(20)이 함께 점등된 상태를 유지하게 된다.That is, when the size of the sensing signal decreases below the first set value, the microcomputer 20 turns on the first switch unit 50 connected to the tail light 10, and the size of the sensing signal When the reduction is less than the second set value smaller than the first set value, the second switch unit 60 connected to the headlamp 20 is turned on, and as a result, when the magnitude of the sensing signal decreases below the second set value, Both the first and second switch units 50 and 60 connected to the tail light 10 and the headlamp 20 are turned on to maintain a state in which the tail light 10 and the headlamp 20 are turned on together.
상기와 같이 구성되는 본 발명에 따른 차량의 미등 및 전조등 자동 점등 장치의 동작을 살펴보면 다음과 같다.Looking at the operation of the taillight and headlight automatic lighting device of the vehicle according to the present invention configured as described above are as follows.
본 발명에 따른 차량의 미등 및 전조등 자동 점등 방법은 도 2 에 도시된 바와 같이, 먼저 제 1 단계에서 상기 센서부(30)에서 차량 외부의 밝기를 감지하고, 그 감지 결과에 따른 크기의 센싱 신호가 생성 출력된다.(S1 및 S2 참조)In the method of automatically lighting the taillights and the headlights of the vehicle according to the present invention, as shown in FIG. 2, first, in the first step, the sensor unit 30 senses the brightness of the outside of the vehicle, and a sensing signal having a magnitude according to the detection result. Is generated and output (see S1 and S2).
즉, 상기 포토 다이오드 등으로 이루어진 센서부(30)에서 상기 차량 외부의 밝기에 따라 다른 크기의 전류가 생성 출력되는 것이다.That is, the sensor unit 30 including the photodiode or the like generates and outputs a current having a different size according to the brightness of the outside of the vehicle.
제 2 단계는 상기 제 1 단계에서 출력된 센싱 신호가 상기 마이컴(40)으로 전달되고, 상기 마이컴(40)은 상기 전달된 센싱 신호와 설정치를 비교하게 된다.(S3 참조)In the second step, the sensing signal output in the first step is transmitted to the microcomputer 40, and the microcomputer 40 compares the transmitted sensing signal with a set value (see S3).
제 3 단계는 상기 제 2 단계에서 전달된 센싱 신호의 크기가 제 1 설정치 미만인 경우 상기 마이컴(40)은 상기 미등(10)을 점등시키기 위하여 상기 제 1 스위치부(50)를 온시키게 된다.(S4 및 S5 참조)In the third step, when the magnitude of the sensing signal transmitted in the second step is less than the first set value, the microcomputer 40 turns on the first switch unit 50 to turn on the tail light 10. See S4 and S5)
제 4 단계는 상기 제 3 단계에서 제 1 스위치부(50)가 온됨에 따라 상기 미등(10)이 점등된다.(S6 참조)In the fourth stage, the tail light 10 is turned on as the first switch unit 50 is turned on in the third stage (see S6).
제 5 단계는 상기 제 4 단계의 미등(10) 점등 후 상기 마이컴(40)은 상기 센싱 신호의 크기를 상기 제 1 설정치보다 작은 제 2 설정치와 비교하게 된다.(S7 참조)In the fifth step, after the tail light 10 of the fourth step is turned on, the microcomputer 40 compares the magnitude of the sensing signal with a second set value smaller than the first set value (see S7).
제 6 단계는 상기 제 5 단계의 비교 결과 상기 센싱 신호가 상기 제 2 설정치 미만인 경우 상기 마이컴(40)은 상기 제 2 스위치부(60)를 온시켜 상기 전조등(20)이 온되도록 한다.(S8 및 S9 참조)In the sixth step, when the sensing signal is less than the second set value as a result of the comparison in the fifth step, the microcomputer 40 turns on the second switch unit 60 so that the headlamp 20 is turned on. And S9)
이때, 상기 6 단계에서 상기 제 2 스위치부(60)가 온되는 경우 상기 제 1 스위치부(50)도 온 상태를 유지하고 있기 때문에 상기 센싱 신호가 상기 제 2 설정치 미만인 경우에는 상기 미등(10)과 전조등(20)이 함께 점등된다.In this case, when the second switch unit 60 is turned on in the sixth step, since the first switch unit 50 is also maintained in the on state, when the sensing signal is less than the second set value, the taillight 10 is turned on. And headlights 20 are lit together.
상기와 같이 구성되는 본 발명에 따른 차량의 미등 및 전조등 자동 점등 장치 및 방법은 차량 주위가 어두워질 경우 포토 다이오드 등으로 이루어진 센서부를 통해 이를 감지하고, 상기 센서부에서 출력되는 센싱 신호의 크기가 설정치 미만으로 감소하게 되면, 상기 미등과 전조등을 순차적으로 점등시킬 수 있도록 하여 운전자가 야간 주행시 미등 및 전조등을 점등시키지 않고 주행할 경우 발생하는 차량 사고 등의 위험을 사전에 방지할 수 있는 효과가 있다.The apparatus and method for automatically lighting the taillights and the headlights of the vehicle according to the present invention configured as described above detects them through a sensor unit including a photodiode, etc., when the surroundings of the vehicle become dark, and the magnitude of the sensing signal output from the sensor unit is set to a set value. When the reduction is less than, it is possible to sequentially turn on the taillights and the headlights, thereby preventing the risk of a vehicle accident, which occurs when the driver does not turn on the taillights and the headlights at night, in advance.
