본 발명은 측방차량의 차선변경 경고장치에 관한 것으로, 좀더 상세하게는 운전중에 확인하기 어려운 측방차량의 차선변경에 대비하여 방어운전할 수 있도록 하는 측방차량의 차선변경 경고장치에 관한 것이다.The present invention relates to a lane change warning device for a side vehicle, and more particularly, to a lane change warning device for a side vehicle to enable a defensive operation in preparation for a lane change of a side vehicle that is difficult to check during driving.

운전자들은 차량운행중에 교통상황을 확인하기 위해 주로 전방을 주시하지만, 수시로 백미러나 사이드밀러를 통해서 후방과 측방을 확인하여야만 돌발할 수 있는 사고를 미연에 방지할 수 있다. 그러나 종래에는 운전자가 상기한 백미러나 사이드미러로 측방에 근접하여 나란히 주행하는 자동차를 확인할 수 없어 돌발적인 상황에 당황하는 경우가 많았다. 특히, 옆차선에서 나란히 주행하던 자동차가 갑자기 추월하면서 차선변경하고자 하는 경우에는 더욱 그러하다.Drivers often look ahead to check traffic conditions while the vehicle is in motion, but they often need to check rear and side through rear-view mirrors or side-mirrors to prevent accidents that can break out. However, in the past, the driver was often embarrassed in an unexpected situation because the rear mirror or the side mirror could not identify a vehicle traveling side by side close to the side. In particular, this is especially true when a car that is traveling side by side in a lane passes suddenly overtaking and wants to change lanes.

일반적으로, 운전자의 시야는 차의 주행속도가 고속이 될수록 더욱 좁아지게 되는 바, 고속주행중에 전방을 주시하는 상태에서는 측방의 상황확인이 불가능하다. 따라서 운전자는 시선을 돌려서 측방자동차의 주행상황을 확인하여야 하는데 자동차는 그사이에 수십미터의 거리를 주행하게 되므로 교통사고를 유발할 우려가 있다는 문제점이 있었다. 이러한 문제점을 해결하기 위한 본발명은 자동차의 운전중에 전방을 주시한 상태에서는 확인하기 어려운 측방차량의 차선변경을 감지하고 이를 운전자에게 경고 되도록 함으로써 측방차량의 차선변경에 대비할 수 있도록 하려는 목적이 있다.In general, the driver's field of view becomes narrower as the driving speed of the car becomes higher, so it is impossible to check the situation of the side in the state of looking forward while driving at a high speed. Therefore, the driver should turn to his eyes to check the driving situation of the side car, but the car runs a distance of several tens of meters in between, causing a traffic accident. The present invention for solving this problem is to prepare for lane change of the side vehicle by detecting a lane change of the side vehicle, which is difficult to check in the state of watching the front while driving the vehicle and alerts the driver.

이와 같은 목적을 달성하기 위한 본 발명에 따르면, 차체의 양 측면에 각각 설치되어 측방차량(B) 방향지시등(2)의 입사광을 적, 녹, 청의 빛으로 분해한 후 각각의 전기신호로 변환하는 칼라센서(10)와, 상기 칼라센서(10)에서 출력되는 각각의 전기신호를 증폭하는 증폭기들(21~23)과 상기 증폭기들 (21∼23)에서 증폭된 신호들을 샘플링하며 적, 녹, 청의 광량비를 검출하여서 입사광 칼라와 기설정된 방향지시등(2) 칼라의 유사여부를 판별하는 마이컴(30)과, 상기 마이컴(30)의 출력단에 접속되어 측방차량(B)의 방향지시등(2)이 점등되면 경고 신호를 발하는 경고발생수단(40)으로 구성되는 것을 특징으로 하는 측방차량의 차선변경 경고 장치가 제공된다.According to the present invention for achieving the above object, respectively installed on both sides of the vehicle body to decompose the incident light of the side vehicle (B) direction indicator (2) into red, green, blue light and then to convert each electric signal The color sensor 10, the amplifiers 21 to 23 for amplifying each electric signal output from the color sensor 10 and the signals amplified by the amplifiers 21 to 23, and red, green, The microcomputer 30 which detects the light quantity ratio of blue and determines whether the incident light color and the preset direction indicator light 2 are similar, and the direction indicator light of the side vehicle B connected to the output terminal of the microcomputer 30. When turned on is provided with a lane change warning device for a side vehicle, characterized in that consisting of warning means for emitting a warning signal (40).

이하, 도면을 참조하여 본 발명의 바람직한 실시예를 더욱 상세히 설명한다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention in more detail.

제1도는 본 발명의 블록도이고, 제2도는 본 발명에 의한 칼라센서의 설치상태도이며, 제3도는 본 발명에 의한 칼라센서의 구조도이다.1 is a block diagram of the present invention, Figure 2 is a state diagram of the installation of the color sensor according to the present invention, Figure 3 is a structural diagram of the color sensor according to the present invention.

본발명은 제1도에 도시한 바와 같이, 차체의 양 측방에 각각 설치되어 입사광을 적, 녹, 청의 빛으로 분해한 후 각각의 전기신호로 변환하는 칼라센서(10)의 출력단에 다수의 증폭기가 접속되며, 상기 증폭기들 (21∼23)의 출력단에는 증폭기에서 증폭된 신호들을 샘플링하여 적, 녹, 청의 광량비를 검출하여서 입사광의 칼라와 기설정된 방향지시등(2)의 칼라의 유사여부를 판별하는 마이컴(30)이 접속되고, 상기 마이컴(30)의 출력단에는 경고 발생수단(40)이 접속되어 측방차량(B)의 방향지시등(2)이 점등될 때 경고 신호를 발하도록 구성된다.As shown in FIG. 1, the present invention has a plurality of amplifiers installed at both sides of the vehicle body, each of which is output to the output of the color sensor 10 that decomposes incident light into red, green, and blue light and converts the light into electrical signals. Is connected to the output terminals of the amplifiers 21 to 23, and the signals amplified by the amplifier are sampled to detect the ratio of red, green, and blue light to determine whether the color of the incident light and the color of the preset direction indicator 2 are similar. A microcomputer 30 for discriminating is connected, and a warning generating means 40 is connected to the output terminal of the microcomputer 30 so as to emit a warning signal when the direction indicator 2 of the side vehicle B is turned on.

상기 칼라센서(10)는 제2도에 도시한 바와 같이, 측방차량(B)에서 발하는 방향지시등(2)의 빛이 입사되기 용이한 위치인 본 차량(A)의 양 측방, 예를 들어 양측 팬더패널(4)에 설치된다.As shown in FIG. 2, the color sensor 10 is located at both sides of the vehicle A, for example, at both sides, where the light of the turn signal 2 emitted from the side vehicle B is easily incident. It is installed in the panda panel (4).

또한, 상기 칼라센서는(10)는 제3도에 도시한 바와 같이, 각각 분리형성되어 자연광중에서 일정파장의 빛만을 투과시키는 다수개의 칼라필터들 (11∼13)과, 이 칼라필터들(11∼13)배면에 각각 구비된 포토다이오드(16∼18)로 구성된다.In addition, the color sensor 10 is a plurality of color filters (11 to 13), each of which is separately formed to transmit only a certain wavelength of light in natural light, as shown in FIG. And photodiodes 16 to 18 respectively provided on the rear surface.

상기 칼라필터들 (11∼13)은 각각 적, 녹, 청색의 빛만을 투과시키도록 된 것이며, 상기포토다이오드(16∼18)는 일반적인 것이므로, 자세한 설명은 생략한다.The color filters 11 to 13 transmit only red, green, and blue light, respectively, and the photodiodes 16 to 18 are general, and thus, detailed description thereof will be omitted.

도면의 미설명한 도면부호는 f는 빛을 투과시키는 유리기판이며, 도면부호는 c는 상기 상기 증폭기(21∼23)가 접속되는 포토다이오드(16∼18)의 뒷면전극을 도시한 것이고, 도면부호 d는 리드프레임을 도시한 것이다.Unexplained reference numerals in the drawings indicate that f is a glass substrate that transmits light, and c indicates the rear electrodes of the photodiodes 16 to 18 to which the amplifiers 21 to 23 are connected. d shows the lead frame.

상기 포토다이오드(16∼18)의 배면에는 고트수지(e)가 도포되어 외부로부터 절연되도록 구성된다. 따라서, 외부의 빛이 칼라센서(10)에 비추면, 이 칼라필터들 (11∼13)은 각각 적, 녹, 청색의 빛만을 투과시킨다. 따라서, 이 칼라필터들 (11∼13)의 배면에 각각 배치된 포토다이오드(16∼18)에 상기 칼라필터들 (11∼13)를 통과한 적, 녹, 청색의 빛이 비추게 되고 이러한 적, 녹, 청색의 빛의 강도에 따라, 각각의 포토다이오드(16∼18)에서 전압이 출력된다. 따라서 상기 포토다이오드(16∼18)에 연결된 마이컴(30)이 각 포토다이오드(16∼18)에서 발생된 전압의 비율을 비교하여, 빛의 삼원색인 적, 녹, 청의 비율을 판단할 수 있으며, 이에 따라, 빛이 차량의 방향지시등에서 발광되는 노란색인지의 여부를 판단하게 된다.On the back surface of the photodiodes 16 to 18, a goth resin (e) is coated to be insulated from the outside. Therefore, when external light shines on the color sensor 10, these color filters 11 to 13 transmit only red, green and blue light, respectively. Accordingly, red, green, and blue light passing through the color filters 11 to 13 is reflected on the photodiodes 16 to 18 disposed on the rear surfaces of the color filters 11 to 13, respectively. Voltages are output from the respective photodiodes 16 to 18 according to the intensity of light of green, green and blue. Therefore, the microcomputer 30 connected to the photodiodes 16 to 18 compares the ratio of voltages generated at each photodiode 16 to 18 to determine the ratios of red, green, and blue, which are three primary colors of light. Accordingly, it is determined whether the light is yellow that is emitted from the direction indicator of the vehicle.

이와 같이 구성되는 본 발명의 작용과 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

먼저, 측방의 자동차가 차선변경을 하려고 방향지시등(2)를 점등하면, 칼라센서(10)는 방향지시등(2)로부터 입사된 빛이 칼라필터들 (11∼13)를 통해서 빛의 3원색의 적, 녹, 청의 빛으로 분해되고, 상기 포토다이오드들 (16∼18)은 이러한 빛의 광량에 대응한 전압의 신호를 각각 출력한다.First, when the vehicle on the side turns on the turn signal light 2 to change lanes, the color sensor 10 causes the light incident from the turn signal light 2 to pass through the three primary colors of light through the color filters 11 to 13. It is decomposed into red, green, and blue light, and the photodiodes 16 to 18 respectively output signals of a voltage corresponding to the amount of light.

이와 같이 광량에 대응한 전압의 신호들은 각각의 증폭기(21∼23)를 거치면서 마이컴(30)에서 인식될 수 있는 레벨의 신호로 증폭되고, 상기 마이컴(30)은 입력된 각 신호들의 전압에 의해 입사광의 적, 녹, 청의 광량을 검출한 후 메모리에 기설정되어 있는 방향지시등(2)의 색상과 비교하게 된다. 즉, 마이컴(30)에는 황색을 띤 방향지시등(2)의 칼라를 적, 녹, 청의 비율에 대한 데이터, 예를 들어 5:5:2의 데이터로 입력되는 동시에 약간의 오차를 포함하여 메모리된다. 이때, 칼라센서(10)를 통해 입사광에서 분해된 적, 녹, 청의 비율이 상기한 바와 같이 오차를 포함한 5:5:2에 유사하다면, 마이컴(30)은 이 빛이 측방차량(B)의 방향지시등(2)에서 발생된 것으로, 측방차량(B)의 방향지시등(2)이 점등되고 있음을 판별하게 된다. 따라서, 상기한 바와 같이 측방차량(B)의 사천변경여부를 판별한 마이컴(30)은 경고 발생수단(40)으로 제어신호를 출력하고, 경고 발생수단(40)은 경고 신호를 발함으로써, 본차량(A)의 운전자는 측방차량(B)의 차선변경을 알 수 있게 된다.As such, signals having a voltage corresponding to the amount of light are amplified into signals having a level that can be recognized by the microcomputer 30 through the respective amplifiers 21 to 23, and the microcomputer 30 is applied to the voltages of the input signals. By detecting the amount of red, green, and blue light of the incident light, it is compared with the color of the turn indicator 2 preset in the memory. That is, the microcomputer 30 inputs the color of the yellowish indicator light 2 as red, green, and blue data, for example, data of 5: 5: 2, and is stored with some errors. . At this time, if the ratio of red, green, and blue decomposed from the incident light through the color sensor 10 is similar to 5: 5: 2 including an error as described above, the microcomputer 30 determines that the light of the side vehicle B It is generated by the turn indicator 2, and it is determined that the turn indicator 2 of the side vehicle B is turned on. Accordingly, as described above, the microcomputer 30 having determined whether the side vehicle B is changed or not is output a control signal to the warning generating means 40, and the warning generating means 40 issues a warning signal. The driver of the vehicle A can know the lane change of the side vehicle B.

이상에서 설명한 바와 같이 본 설명은 차선변경하는 측방차량을 방향지시등에 의해서 감지하고 이를 경고 하도록 함으로써 운전자가 차선변경차량에 대비한 방어운전할 수 있도록 하여 사고를 방지하는 효과가 있다.As described above, the present description has an effect of preventing an accident by allowing a driver to defensively prepare for a lane change vehicle by detecting a side vehicle changing lane by a direction indicator and warning the warning.
