Description

야간주행시 조명등 및 CCD카메라 제어방법Lighting and CCD Camera Control Method at Night

본 발명은 야간주행시 조명등 및 CCD카메라 제어에 관한 것으로, 특히 야간에 차량을 후진시 속도센서와 기어의 동작상태를 자동체크하여 전조등 및 라이트, CCD 카메라를 자동으로 온, 오프시켜 접촉사고를 방지하도록 한 야간주행시 조명등 및 CCD카메라 제어방법에 관한 것이다.The present invention relates to lighting and CCD camera control at night driving, in particular to automatically check the operating state of the speed sensor and gear when the vehicle is retracted at night to automatically turn on and off the headlight, light, CCD camera to prevent contact accidents The present invention relates to a control method of a lighting lamp and a CCD camera when driving at night.

종래에는 야간주행시 동승자가 물건을 찾거나 또는 책이나 신문을 보는 등의 이유로 실내등을 점등시켰을 때 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 searching for an object or reading a book or newspaper during a night driving, the interior of the room is reflected by a wind shield, so that the indoor light cannot be used when driving, or the lighting is minimized. This is also the case when reversing.

또한, 자동차의 후면에는 밝은 라이트가 없어 야간에 주차하기 위해 후진할 때 자동차 뒷부분의 조명이 어두위 후방시야가 확보되지 않아 접촉사고의 위험성이 높다.In addition, there is no bright light at the rear of the car, so when the vehicle is backed up to park at night, the rear part of the car does not have a dark rear field of view, so there is a high risk of contact accidents.

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 1/2인치형 컬러 모니터 카메라(3)를 승용차의 리어 스포일러에 내장시키고, 카메라(3)의 렌즈에는 후방 시야각을 넓게하기 위해 초광각 렌즈가 사용되며, 이그니션 스위치가 온(on)에서 트랜스미션의 시프트 위치를 R렌지(후퇴)로 하면 멀티디스플레이(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 embedded 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. When the shift position of the transmission is set to R range (retract) at (on), an 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 가장자리 주의! 후퇴시는 후방을 직접 확인해 주세요"라는 메시지가 3초마다 반복되고 슈퍼 인포즈된다.In addition, for safety reasons, the monitor screen repeats the message "Caution on both edges! Please check the rear directly when retreating" to recognize the driver as the assist device for retreating the vehicle.

상기 CCD 영상소자는 수 mm 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 mm angle, 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 조도시에도 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.Also, even in low light at night, obstacles can be identified by only the illumination by 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, 야간주행시 실내등을 점등시켰을 때 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.

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

상기의 목적을 달성하기 위한 구체적인 수단으로, 전조등이 작동하고 있는 상태에서 후진기어가 들어가면 전조등의 하향등 조정 및 라이트(A,B,C)가 점등되고 CCD 카메라가 동작되는 단계와, 이후 드라이브 모드에서 전조등 조도의 원상복귀 및 라이트(A,B,C)가 점등상태를 유지하고 CCD카메라가 동작상태를 유지하는 단계와, 이후 주행속도가 15km 이상이면 상기 라이트(A,B,C) 및 CCD 카메라가 오프되는 단계로 이루어지는 것을 특징으로 한다.As a specific means for achieving the above object, when the reversing gear enters the state in which the headlight is operating, the downlight adjustment of the headlight and the lights (A, B, C) are turned on and the CCD camera is operated, and then the drive mode. Reverting the headlight illuminance and maintaining the lights (A, B, C) in the lighting state and maintaining the CCD camera in the operation state, and if the driving speed is 15 km or more, the lights (A, B, C) and CCD Characterized in that the step of turning off the camera.

이하, 본 발명의 실시예를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명 야간주행시 조명등 및 CCD카메라 제어방법으로서, 전조등(1)(headlight)이 작동하고 있는 상태에서 후진기어가 들어가면 전조등(10)의 하향등 조정 및 라이트(light)(A,B,C)가 점등(on)되고 CCD카메라(30)가 동작되는 단계와(S1-S3), 이후 드라이브 모드에서 전조등(10) 조도의 원상복귀 및 라이트(A,B,C)가 점등상태를 유지하고 CCD 카메라(30)가 동작상태를 유지하는 단계와(S4-S5), 이후 주행속도가 15km 이상이면 상기 라이트(A,B,C) 및 CCD 카메라(30)가 오프(off)되는 단계(S6-S7)로 이루어지는 것으로, 이의 동작과정을 도 3 및 도 4를 참조하여 상세히 설명하면 다음과 같다.2 is a method for controlling a lighting lamp and a CCD camera at night driving of the present invention, when the reverse gear is entered while the headlight 1 is operating, the downlight adjustment of the headlamp 10 and the light A, B, C) is turned on and the CCD camera 30 is operated (S1-S3), and then the original mode of illumination of the headlamp 10 and the lights A, B, and C remain lit in the drive mode. And maintaining the operation state of the CCD camera 30 (S4-S5), and then turning off the lights A, B, C and the CCD camera 30 when the traveling speed is 15 km or more ( S6-S7), the operation process thereof will be described in detail with reference to FIGS. 3 and 4 as follows.

차량 후방의 좌우측에 보조 라이트(A,B,C)를 설치하고, 후방의 범퍼에 보조라이트(C)를 설치하여 야간에 전조등(10)이 작동하고 있는 상태에서 차량의 후진기어가 들어갔을 경우 운전자의 조작상의 번거로움을 피하기 위해 자동으로 보조 라이트(A,B,C)가 점등되며 동시에 전조등(10)을 하향등으로 자동 조정한다.When the auxiliary gears (A, B, C) are installed on the left and right sides of the rear of the vehicle, and the auxiliary lights (C) are installed on the rear bumpers, and the reverse gear of the vehicle enters at night with the headlight (10) operating. Auxiliary lights (A, B, C) is automatically turned on to avoid the driver's troublesome operation, and at the same time, the headlight 10 is automatically adjusted to a downlight.

이때 CCD카메라(30)를 작동시켜 야간에 차량을 후진할 경우 운전자의 편의를 도모하고, 상기 라이트(A,B,C) 및 CCD 카메라(30)가 점등된 상태에서 운전자가 후진기어 모드에서 드라이브 모드로 기어 변환을 하면 일단 전조등(10)을 후진하기 전의 상태로 복귀시킨다.At this time, if the driver reverses the vehicle at night by operating the CCD camera 30, the driver's convenience is achieved, and the driver drives in the reverse gear mode while the lights A, B, and C and the CCD camera 30 are turned on. When the gear is switched to the mode, the headlamp 10 is returned to the state before the reverse.

한편, 속도센서가 차량의 속도를 감지하여 시속 15km 이상이 되면 운전자가 더 이상 후진할 의사가 없는 것으로 판단하여 보조 라이트(A,B,C)와 CCD 카메라(30)를 자동 오프시킨다.On the other hand, when the speed sensor detects the speed of the vehicle and the speed is more than 15km per hour, the driver determines that there is no intention to back up any more, and automatically turns off the auxiliary lights A, B, and C and the CCD camera 30.

이상에서 설명한 바와 같이 본 발명은 야간주행시 후진할 경우 후방조명을 자동조작하여 밝게 하여주고, CCD 카메라를 자동으로 온, 오프시킴으로써 운전자의 편의가 도모되고 후진시 안전성이 증대되어 접촉사고를 미연에 방지할 수 있는 효과가 있다.As described above, in the present invention, when driving backward at night, the rear lighting is automatically operated to brighten, and the CCD camera is automatically turned on and off to facilitate the driver's convenience and to increase safety when moving backward, thereby preventing contact accidents. It can work.
