본 발명은 자동차의 사각지대를 감소시키기 위한 아웃사이드미러 제어시스템 및 그 방법에 관한 것으로서, 후측방경보작동스위치의 ON 상태시 후측방레이더센서가 활성화된 상태에서 상기 방향지시등스위치의 스위치 신호가 입력되면, 상기 후측방레이더센서로부터 전달받는 신호와 상기 SVM 모듈로부터 전달되는 영상에 기초하여 후측방으로부터 접근하는 차량의 영역을 도출하여, 아웃사이드조절모터를 구동하여 해당 차량의 영역이 보일 수 있도록 아웃사이드미러의 시야각을 조절하는 제어부를 포함하여 구성되는 것을 특징으로 하는 아웃사이드미러 제어시스템 및 그 방법에 관한 것이다.The present invention relates to an outside mirror control system and method for reducing a blind spot of a vehicle, and relates to an outside mirror control system and method thereof, wherein a switch signal of a direction indicator light switch is input in a state in which a rear side radar sensor is activated when a rear side warning operation switch is in an ON state Then, based on the signal transmitted from the rear side radar sensor and the image transmitted from the SVM module, the area of the vehicle approaching from the rear side is derived, and the outside control motor is driven so that the area of the vehicle can be seen. It relates to an outside mirror control system and method comprising a control unit for adjusting the viewing angle of a side mirror.

일반적으로, 자동차의 사각지대는 운전자의 시야에 직접 보이지 않을 뿐만 아니라, 차량 실내의 후방미러(back mirror)나 차량 좌우측의 아웃사이드미러(outside mirror)에도 보이지 않는 영역을 가리킨다. In general, a blind spot of a vehicle refers to an area that is not directly visible to the driver's field of view and is also invisible to the rear mirror inside the vehicle or the outside mirrors on the left and right sides of the vehicle.

이러한 사각지대는 차량의 운행중 사고를 유발할 수 있어 운전자가 사각지대를 감안하여 운행에 주의를 기울여야 한다.Such a blind spot may cause an accident while driving the vehicle, so the driver should pay attention to driving in consideration of the blind spot.

이러한 사각지대를 해소하기 위하여, 차량 전방 및 후방의 영상을 카메라로 촬영하여 차량의 AVN 시스템으로 보여주는 전방카메라와 후방카메라, 차량 후진시 후방에 위치한 사람이나 물체를 감지하여 경보를 출력하는 후방감지센서 등이 활용되고 있다.In order to solve these blind spots, a front camera and a rear camera take images of the front and rear of the vehicle and show them through the vehicle's AVN system, and a rear detection sensor that detects people or objects located in the rear and outputs an alarm when the vehicle is reversing. etc. are being used.

또한, 후측방경보시스템(Blind Spot Detection, BSD)라 불리우는 시스템도 적용되고 있는데, 상기 후측방경보시스템은 차량의 후방에 레이더센서(Radar sensor)를 설치하여, 차량의 후측방으로부터 접근하는 차량을 감지하여 아웃사이드미러에 후측방으로 차량이 접근중임을 경보를 표시하는 시스템으로서, 아웃사이드미러의 사각지대를 해소하는데 도움을 주고 있다.In addition, a system called Blind Spot Detection (BSD) is also being applied. The blind spot detection system installs a radar sensor at the rear of the vehicle to detect a vehicle approaching from the rear of the vehicle. It is a system that detects and displays a warning that a vehicle is approaching from the rear side to the outside mirror, helping to eliminate the blind spot of the outside mirror.

나아가, 서라운드 뷰 모니터(SVM, Surround View Monitor)라 불리우는 시스템도 활용되고 있는데, 차량에 190 도를 투영할 수 있는 초광각 카메라 4 개를 부착하여 차량의 주변부의 영상을 360 도로 내려다보는 시야를 AVN 시스템으로 보여주는 시스템으로서, 주로, 주차시 차량의 사방의 상황을 운전석에서 확인할 수 있도록 하여 안전사고 예방에 도움을 주는 시스템이다.Furthermore, a system called the Surround View Monitor (SVM) is also being used, and by attaching four ultra-wide-angle cameras that can project 190 degrees to the vehicle, the AVN system provides a 360-degree view of the surroundings of the vehicle. It is a system that helps prevent safety accidents by allowing the driver to check the situation in all directions of the vehicle when parking.

그러나, 상술한 바와 같은 시스템들을 적용하여 운행을 하여도, 아웃사이드미러 주위의 사각지대는 여전히 상존하고 있어 운행상 주의를 기울여야 하며, 특히, 아웃사이드미러의 후측방경보시스템(BSD)을 적용한 차량에서 후측방으로 차량이 접근할 경우 아웃사이드미러에 경보가 표시되어도 접근중인 차량은 보이지 않는 경우가 많아 운전자가 자칫 방심할 수 있는 우려가 있었다.However, even when driving with the above-described systems applied, blind spots around the outside mirrors still exist, so care must be taken while driving. In the case of a vehicle approaching from the rear side, even if an alarm is displayed on the outside mirror, the approaching vehicle is often not visible, so there is a concern that the driver may be careless.

또한, 야간에는 아웃사이드미러 주변부가 어두워 아웃사이드미러에 보여지는 차량이 잘 안보여 불편한 문제점도 상존한다.In addition, at night, the periphery of the outside mirror is dark, and the vehicle shown in the outside mirror is not well seen, causing an uncomfortable problem.

본 발명은 상기와 같은 종래의 제반 문제점을 해소하기 위하여 창안된 것으로서, 후측방경보시스템에 의한 경보 표시뿐만 아니라 후측방에 접근중인 차량을 아웃사이드미러에 보여줄 수 있도록 하여 운전자에게 확실하게 경보를 줄 수 있으며, 나아가, 야간에도 아웃사이드미러를 잘 보일 수 있도록 하는 구성을 제공하는 것에 본 발명의 기술적 과제가 있다. The present invention was conceived to solve the above-mentioned problems of the prior art, and not only displays an alarm by the rear side warning system, but also shows a vehicle approaching the rear side in the outside mirror, thereby giving a reliable warning to the driver. Furthermore, there is a technical problem of the present invention to provide a configuration that allows the outside mirror to be well visible even at night.

상기와 같은 기술적 과제를 달성하기 위한 본 발명의 사각지대 개선을 위한 아웃사이드미러 제어시스템 및 그 방법은, 후측방경보작동스위치의 ON 상태시 후측방레이더센서가 활성화된 상태에서 상기 방향지시등스위치의 스위치 신호가 입력되면, 상기 후측방레이더센서로부터 전달받는 신호와 상기 SVM 모듈로부터 전달되는 영상에 기초하여 후측방으로부터 접근하는 차량의 영역을 도출하여, 아웃사이드조절모터를 구동하여 해당 차량의 영역이 보일 수 있도록 아웃사이드미러의 시야각을 조절하는 제어부를 포함하여 구성되는 것을 특징으로 한다.In order to achieve the above technical problem, an outside mirror control system and method for improving blind spots of the present invention are provided in a state in which a rear side radar sensor is activated when a rear side warning operation switch is in an ON state, and a direction indicator switch is activated. When the switch signal is input, the area of the vehicle approaching from the rear side is derived based on the signal received from the rear side radar sensor and the image transmitted from the SVM module, and the outside control motor is driven to determine the area of the vehicle. It is characterized in that it is configured to include a control unit for adjusting the viewing angle of the outside mirror so that it can be seen.

상기와 같은 구성을 가지는 본 발명의 사각지대 개선을 위한 아웃사이드미러 제어시스템 및 그 방법은, SVM 카메라와 후측방경보를 위한 레이더를 이용하여 후측방에 접근중인 차량을 아웃사이드미러에 보여줌으로써 운전자에게 보다 확실하게 후측방에 대한 경보를 줄 수 있어 차량 운행상의 안전성을 향상시킬 수 있는 효과가 있다.The outside mirror control system and method for improving the blind spot of the present invention having the configuration as described above shows a vehicle approaching from the rear side on the outside mirror using an SVM camera and a radar for rear side traffic warning, thereby showing the driver in the outside mirror. It is possible to more reliably give a warning about the rear side to the driver, which has the effect of improving vehicle driving safety.

또한, 아웃사이드미러에 아웃사이드램프를 설치하여 야간에 아웃사이드미러를 잘 보일 수 있도록 함으로써 야간 운행시 안전성을 제고시킬 수 있게 된다.In addition, by installing an outside lamp on the outside mirror so that the outside mirror can be clearly seen at night, safety during night driving can be improved.

From the rear side warning operation switch 30 that activates the rear side warning system (BSD) that detects the presence of a vehicle approaching from the rear side of the vehicle by the sensor signal and displays an alarm on the outside mirror, and the ultra-wide angle camera installed in the vehicle A surround view monitor (SVM) module 40 for receiving and displaying images of the surrounding area of the vehicle and displaying them on the display, an outside adjusting motor 60 for adjusting the viewing angle of the outside mirror, and installed in the housings of the left and right outside mirrors When the outside mirror lamp 70 and the rear side warning operation switch 30 are ON, the rear side radar sensor 50 is activated, and the switch signal of the turn indicator switch 20 is activated. When is input, the area of a vehicle approaching from the rear side is derived based on the signal received from the rear side radar sensor 50 and the image transmitted from the SVM module 40, and the outside control motor 60 is driven. It is configured to include a control unit 10 that adjusts the viewing angle of the outside mirror so that the corresponding area can be seen.

또한, 상기 제어부(10)는 야간 운행시 방향지시등스위치(20)가 ON 상태로 되면 해당 방향의 아웃사이드미러의 아웃사이드미러램프(70)를 점등시켜, 야간운행시 아웃사이드미러를 잘 보일 수 있도록 제어한다.In addition, when the direction indicator switch 20 is turned on during night driving, the controller 10 turns on the outside mirror lamp 70 of the outside mirror in the corresponding direction, so that the outside mirror can be clearly seen during night driving. control so that

이때, 상기 제어부(10)는 차량이 야간 운행중임을 확인하기 위하여, 차량에 설치된 조도센서를 이용하여 차량 주위의 밝기에 따라서 차량의 전조등을 자동적으로 점등 또는 소등시키는 일명 오토 라이트(auto light) 모듈로부터 조도센서의 신호를 전달받아 차량의 주간 또는 야간 운행을 확인한다. At this time, in order to confirm that the vehicle is running at night, the control unit 10 uses an illuminance sensor installed in the vehicle to automatically turn on or off the headlights of the vehicle according to the brightness around the vehicle from a so-called auto light module. It receives the signal from the illuminance sensor and checks the daytime or nighttime operation of the vehicle.

상기 제어부(10)는 후측방레이더센서(50)로부터 전달받는 신호와 SVM 모듈(40)로부터 전달되는 영상에 따라서 후측방으로부터 접근하는 차량의 영역을 도출하기 위하여, 다음의 방법을 사용한다.The control unit 10 uses the following method to derive the area of a vehicle approaching from the rear side according to the signal received from the rear side radar sensor 50 and the image transmitted from the SVM module 40.
