본 발명은 차량의 야간 주행시 전방 모니터링 장치에 관한 것으로, 특히 차량의 전방 적소에 설치된 적외선 카메라 및 좌/우측 보조 적외선램프를 이용하여 차량의 야간 주행시 전방의 사각지역까지 뚜렷하게 디스플레이함으로써, 운전자가 야간 주행시에도 차량 전방 전체의 상황을 용이하게 파악하여 사고를 미연에 방지할 수 있는 차량의 야간 주행시 전방 모니터링 장치에 관한 것이다.The present invention relates to a front monitoring device during night driving of a vehicle, and particularly by using an infrared camera and a left / right auxiliary infrared lamp installed at a right position in front of the vehicle to clearly display the blind spots in front of the vehicle at night, so that the driver can drive at night. In addition, the present invention relates to a front monitoring device during the night driving of the vehicle that can easily grasp the situation in front of the vehicle to prevent accidents in advance.

일반적으로, 차량의 주행에 있어서 전방의 시야확보는 전적으로 운전자의 시각에 의존하게 된다. 그러나, 일광이 있는 주간과는 달리 야간에는 주로 전조등의 조명에 의지하여 주행하게 되는데, 이는 주간에 비하여 시야가 좁아지고 주의를 뺏기기 쉽고, 더욱이 안개가 낀 날이나 우천시의 야간 주행은 주변의 조도가 낮기 때문에 시야확보가 곤란하여 사고의 위험이 배가된다.In general, the visibility of the front in driving a vehicle depends entirely on the driver's vision. However, unlike daytime with daylight, driving at night is mainly dependent on the lighting of headlights, which is narrower than the daytime and is easier to be distracted, and moreover, nighttime driving in fog or rainy weather Because of the low visibility, it is difficult to secure the field of view, which doubles the risk of an accident.

상기와 같은 문제점을 해결하기 위해 대한민국 실용신안 공개번호 제1998-0007667호(자동차의 야간 운전용 비젼장치)에서는 적외선 카메라를 차내에 장착시켜 야간 운행시 운전자에게 전방 영상을 실시간으로 전달해줌으로써, 야간 운행시 운전자의 시야확보에 도움이 되도록 한 자동차의 야간 운전용 비젼장치가 제안되었다.In order to solve the above problems, Republic of Korea Utility Model Publication No. 1998-0007667 (Vision driving device for night driving of the car) is equipped with an infrared camera in the car to deliver the front image to the driver in real time at night, driving at night A vision device for driving a car at night is proposed to help the city driver secure the vision.

도 1은 종래 자동차의 야간 운전용 비젼장치를 나타낸 구성도로서, 종래 자동차의 야간 운전용 비젼장치는, 차내의 상단에 장착되어 적외선을 피사체로 송출 하고 그 피사체로부터 반사되는 적외선을 전기적신호로 변환하여 영상신호로 출력하는 적외선 카메라(1)와, 적외선 카메라(1)에서 출력된 영상신호로부터 윤곽선만을 추출하는 영상처리부(2)와, 영상처리부(2)에서 추출된 윤곽선을 디스플레이하는 모니터(3)로 구성되어 있다.1 is a configuration diagram showing a vision device for driving at night of a conventional vehicle, the vision device for driving at night of a conventional vehicle is mounted on the upper end of the vehicle to send infrared rays to the subject and convert the infrared rays reflected from the subject into electrical signals An infrared camera 1 for outputting an image signal, an image processor 2 for extracting only contour lines from the image signal output from the infrared camera 1, and a monitor for displaying the contour lines extracted from the image processor 2 It consists of).

As the image of the area is not displayed clearly, the driver may not know the situation of the blind spot accurately.

따라서, 자동차의 운행 중에 좌/우회전하거나 좌/우측으로 차선 변경을 할 때 좌/우측의 사각지역에 물체(전형적으로 또 다른 차량)가 존재하는 것을 운전자가 깨닫지 못하게 되어 여러 가지 치명적인 충돌 사고가 발생하게 되는 문제점이 있다.Therefore, when the driver turns left / right or changes lanes to the left / right while driving, the driver does not realize that an object (typically another vehicle) exists in the left / right blind spot, causing various fatal crash accidents.

좌/우측 보조 적외선발생부(300)(300')는 원통형의 하우징(310)(310') 및 하우징(310)(310')의 일측면에 원주방향으로 일정거리만큼 이격되도록 고정설치된 다수의 좌/우측 보조 적외선램프(320)(320')로 이루어지는 바, 좌/우측 보조 적외선램프(320)(320')가 차량 전방의 사각지역을 향해 적외선을 발생시키도록 차량의 전방 범퍼(350)의 좌/우측에 설치됨이 바람직하지만, 이에 국한하지 않으며, 차량의 전방 그릴(150)의 양측 끝단부에 설치될 수도 있다.The left and right auxiliary infrared generators 300 and 300 'are fixed to be spaced apart by a predetermined distance in the circumferential direction on one side of the cylindrical housings 310 and 310' and the housings 310 and 310 '. The left and right auxiliary infrared lamps 320 and 320 'include a front bumper 350 of the vehicle such that the left and right auxiliary infrared lamps 320 and 320' generate infrared rays toward a blind spot in front of the vehicle. It is preferable to be installed at the left / right side of the, but is not limited thereto, and may be installed at both end portions of the front grill 150 of the vehicle.

여기서, 좌/우측 보조 적외선램프(320)(320')는 소정의 적외선을 발생시키는 것이면 어느 것(예를 들어, 원적외선 램프, 근적외선 램프 등)이라도 상관없지만, 일반적으로 널리 공지된 적외선(Infrared Ray, IR) 발광다이오드(Light Emitting Diode, LED)로 구현됨이 바람직하다.Here, the left and right auxiliary infrared lamps 320 and 320 'may be any ones (for example, far-infrared lamps, near-infrared lamps, etc.) as long as they generate predetermined infrared rays, but generally known infrared rays (Infrared Ray) , IR) Light Emitting Diode (LED).

보조 적외선램프 스위치부(400)는 운전자가 동작시키기 용이하도록 미도시된 차량의 핸들 일측에 구비될 수 있으며, 상기 핸들의 좌측 하방에 미등 및 전조등을 동작시키기 위해 구비된 다기능스위치(미도시)의 일측에 구비될 수도 있다.The auxiliary infrared lamp switch unit 400 may be provided at one side of a handle of a vehicle not shown to facilitate the operation of a driver, and may be provided on a left side of the handle of a multifunction switch (not shown) provided to operate a tail light and a headlight. It may be provided on one side.

디스플레이부(500)는 운전자가 용이하게 볼 수 있도록 차량 내부에 구비된 인스트루먼트 패널(미도시)의 중앙에 설치됨이 바람직하다. 또한, 디스플레이부(500)는 통상의 LCD(Liquid Crystal Display)패널 또는 PDP(Plasma Display Panel)패널로 구성될 수 있다.The display unit 500 is preferably installed in the center of the instrument panel (not shown) provided in the vehicle so that the driver can easily see. In addition, the display unit 500 may be configured of a conventional liquid crystal display (LCD) panel or a plasma display panel (PDP) panel.

한편, 디스플레이부(500)는 보조 적외선램프 스위치부(400)를 온(ON)시킬 경우 자동으로 동작되도록 구성됨이 바람직하지만, 이에 국한하지 않으며, 카 오디오의 전면패널(미도시)에 미도시된 디스플레이부(500)의 전용 온/오프(ON/OFF)동작스위치 또는 외부 영상기기(예컨대, TV 또는 VTR 등)와 적외선 카메라(100)로부터 포착된 전방 영상을 운전자가 임의로 선택해서 볼 수 있도록 전환스위치를 구비할 수도 있다.Meanwhile, the display unit 500 is preferably configured to automatically operate when the auxiliary infrared lamp switch unit 400 is turned on. However, the display unit 500 is not limited thereto, and is not illustrated on the front panel of the car audio. Dedicated ON / OFF operation switch of the display unit 500 or switching so that the driver can arbitrarily select and view the front image captured from an external video device (for example, TV or VTR) and the infrared camera 100. A switch may be provided.

그리고, 제어부(600)는 차량의 전체적인 제어를 담당하는 전자제어유닛(Electronic Control Unit, ECU) 또는 이와 별도로 마련되어 이루어질 수 있다.In addition, the controller 600 may be provided separately from an electronic control unit (ECU) that is in charge of overall control of the vehicle.

따라서, 상기와 같이 구성된 차량의 야간 주행시 전방 모니터링 장치를 장착한 상태에서 야간에 좁은 길을 운행하거나 주차할 때, 주변이 어둡기 때문에 적외선 카메라(100)의 전방 영상을 포착할 수 있는 능력이 떨어지게 된다. 따라서, 운전자는 보조 적외선램프 스위치부(400)를 작동시켜 좌/우측 보조 적외선램프(320)(320')를 온(ON)시켜 차량의 야간 주행시 전방의 사각지역까지 차내의 적소에 설치된 디스플레이부(500)에 뚜렷하게 표시해줌으로써, 운전자가 야간 주행시에도 차량 전방 전체의 상황을 용이하게 파악하여 사고를 미연에 방지할 수 있다.Therefore, when driving or parking a narrow road at night with the front monitoring device mounted at night while the vehicle is configured as described above, since the surroundings are dark, the ability to capture the front image of the infrared camera 100 is inferior. . Accordingly, the driver operates the auxiliary infrared lamp switch unit 400 to turn on the left and right auxiliary infrared lamps 320 and 320 'so that the display unit is installed at the right spot in the vehicle to the blind spot in front of the vehicle at night. By clearly displaying the 500, the driver can easily grasp the entire situation in front of the vehicle even when driving at night, thereby preventing an accident.
