Description

야간주행시 보조등 및 CCD카메라 제어방법Auxiliary light and CCD camera control method at night

본 발명은 야간 주행시보조등 및 CCD카메라 제어에 관한 것으로, 특히 야간에 차량으 후진시 속도센서와 기어의 동작상태를 자동체크하여 전조등 및 보조등, CCD카메라를 자동으로 온,오프시켜 접촉사고를 방지하도록 한 야간주행시 보조등 및 CCD카메라 제어방법에 관한 것이다.The present invention relates to the control of the auxiliary light and CCD camera when driving at night, and in particular, by automatically checking the operating state of the speed sensor and gear when the vehicle reverses at night, the headlight, auxiliary light, and the CCD camera are automatically turned on and off to contact accidents. The present invention relates to an auxiliary light and a CCD camera control method for driving at night.

종래에는 야간주행시 동승자가 물건을 찾거나 또는 책이나 신문을 보느 등의 이유로 실내등을 점등시켰을때 윈드 실드(wind shield)에 실내 모습이 반사되어 주행시에는 실내등을 사용할 수 없거나 조명도를 최소로 낮추는 방법을 사용하고 있는데, 이러한 것은 후진시에도 발생된다.Conventionally, when a passenger lights up an indoor light due to a passenger looking for something or reading a book or newspaper during a night driving, the interior of the room is reflected by a wind shield. This is also the case when reversing.

또한, 자동차의 후면에는 밝은 보조등이 없어 야간에 주차하기 위해 후진할 때 자동차 뒷부분의 조명이 어두워 후방시야가 확보되지 않아 접촉사고의 위험이 높다.In addition, there is no bright auxiliary light on the rear of the car, when the back of the car to park at night when the rear lights are dark, the rear view is not secured, there is a high risk of accident.

도 1은 일반적인 CCD카메라가 장착된 차량의 구조도로서, 이에 도시한 바와 같이 자동차 후퇴시에는 직접 눈으로 확인할 수 없는 자동차 후방의 사각을 보충할 목적으로 자동차 뒤쪽 끝에 모니터 카메라가 설치된다.FIG. 1 is a structural diagram of a vehicle equipped with a general CCD camera. As shown in FIG. 1, a monitor camera is installed at the rear end of a vehicle for the purpose of replenishing blind spots in the rear of the vehicle, which are not directly visible when the vehicle is retracted.

한편, 고감도 CCD 영상소자를 사용한 1/2 인치형 컬러 모니터 카메라(3)를 승용차의 리어 스포일러에 내장시키고, 카메라(3)의 렌즈에는 후방시야각을 넓게하기 위해 초광각 렌즈가 사용되며, 이그니션 스위치가 온(on)에서 트랜스미션의 시프트 위치를 R렌지(후퇴)로 하면 멀티 디스플레이(1) 패널(5,9형 TFT-LCD)위에 자동차 후방의 화상이 표시된다.On the other hand, a 1 / 2-inch type color monitor camera 3 using a high-sensitivity CCD imaging element is incorporated in the rear spoiler of a passenger car, and an ultra wide-angle lens is used for the lens of the camera 3 to widen the rear viewing angle, and the ignition switch is turned on. If the shift position of the transmission is set to R-range (retreat) at (on), the image of the rear of the vehicle is displayed on the multi-display 1 panel (5, 9 type TFT-LCD).

또한, 안전상 이 모니터 화면은 자동차 후퇴시의 보조장치라는 요지를 운전자에게 인식시키기 위해"양 가장자라 주의! 후퇴시는 후방을 직접 확인해 주세요"라는 메시지가 3초마다 반복되고 슈퍼 인포즈된다.In addition, for safety reasons, the monitor screen repeats the message, "Attention of both heads! Please check the rear directly when retreating" in order to recognize the driver as an auxiliary device when retreating.

상기 CCD 영상소자는 수 ㎜각의 수광면 위에 579×422개(약 24만 4000개)의 수광소자가 배열되어 있어 수광소자가 받은 광량에 따라 방출하는 전류값을 읽어 화상신호로 출력한다.In the CCD image device, 579 x 422 light receiving elements are arranged on the light receiving surface of several millimeters, and the current value emitted according to the amount of light received by the light receiving element is read and output as an image signal.

그리고, 야간 등의 낮은 조도시에는 백업램프에 의한 조명만으로 장애물을 확인할 수 있고,저온시에는 카메라 내부의 결로를 방지하기 위해 렌즈 앞면의 보호용 유리에는 히터가 삽입되며,카메라 내의 온도는 15℃이하로 작동한다.In low lighting conditions such as nighttime, obstacles can be identified only by the illumination of the backup lamp.At low temperatures, a heater is inserted into the protective glass on the front of the lens to prevent condensation inside the camera. Works.

한편, 야간 주행시 실내등을 점등시켰을때 윈드 실드에 실내 모습이 반사되어 실내등을 사용하기 곤란하고, 야간에 후진시 자동차 후방의 조명이 어두워 후방시야가 확보되지 않아 접촉사고가 발생되는 문제점이 있었다.On the other hand, when the indoor light is turned on during the night driving, the indoor appearance is reflected on the wind shield, making it difficult to use the indoor light, and when the vehicle is reversed at night, the rear light is dark so that a rear view is not secured, resulting in contact accidents.

본 발명은 상기의 문제점을 해소하기 위해 창안된 것으로, 야간에 차량을 후진시 속도센서와 기어의 동작상태를 자동체크하여 전조등,보조등 및 CCD 카메라를 자동으로 온,오프시킴으로써 접촉사고를 방지하는데 그 목적이 있다.The present invention was devised to solve the above problems, to prevent contact accidents by automatically checking the operating state of the speed sensor and gear when the vehicle is retracted at night to turn on and off the headlamp, the auxiliary lamp and the CCD camera automatically. The purpose is.

상기의 목적을 달성하기 위한 구체적인 수단으로, 전조등이 적동하고 있는 상태에서 후진기어가 들어가면 전조등의 하향등 조전 및 보조등 A,B,C가 점등되고 CCD 카메라가 동작되는 단계와, 이후 드라이브 모드에서 전조등 조도의 원상복귀 및 보조등A,B,C가 점등상태를 유지하고 CCD 카메라가 동작상태를 유지하는 단계와, 이후 주행속도가 15㎞ 이상이면 상기 보조등 A,B,C 및 CCD 카메라가 오프되는 단계로 이루어지는 것을 특징으로 한다.As a specific means to achieve the above object, when the reversing gear enters while the headlight is active, the downlight control of the headlight and the auxiliary lights A, B, C are turned on and the CCD camera is operated, and then in the drive mode. Restoring the headlight illuminance and the auxiliary lights A, B, and C remain lit and the CCD camera maintaining the operation state, and if the driving speed is 15 km or more, the auxiliary lights A, B, C and CCD camera Characterized in that the step is made off.
