Description

자동차의 중앙선 침범 경보 장치Central line invasion alarm of car

본 고안은 자동차의 중앙선 침범 경보 장치에 관한 것으로, 특히 차량의 적소에 컬러 디지탈 카메라를 설치하여 자차가 현재 중앙선을 침범하는 지를 감지하고, 중앙선 침범하는 경우에는 경보를 발하는 자동차의 중앙선 침범 경보 장치에 관한 것이다.The present invention relates to a vehicle center line intrusion alarm device of the vehicle, in particular to install a color digital camera in place of the vehicle to detect whether the vehicle is currently invading the center line, and in the case of the center line invasion alarms in the car center line invasion alarm device It is about.

근래 들어, 각종 센서 기술과 전자 제어 기술의 발달에 힘입어서 주행 중인 운전자의 안전을 도모하기 위한 여러 장치들이 다양하게 제안되어 있다. 이러한 장치들은 크게 사고를 미연에 방지하기 위한 사전안전장치와 사고가 일어나 후의 안전을 확보하기 위한 사후안전장치로 구별할 수 있다.In recent years, various devices have been proposed for the safety of the driver while driving due to the development of various sensor technologies and electronic control technologies. These devices can be largely classified into pre-safety devices to prevent accidents and post-safety devices to ensure safety after an accident occurs.

사전안전장치의 예로는 자차의 전방을 향하여 레이저 등의 전파를 발사하고, 이렇게 발사된 전파가 선행 차량의 후미에 부착된 반사판에 맞고 되돌아 오기까지의 시간을 측정하여 자차와 선행차량과의 거리를 연산하고, 이렇게 연산된 거리를 자차의 절대속도에 대입하여 추돌 위험성을 예측하고, 이러한 예측 결과에서 추돌 위험성이 있는 경우에는 경보를 발하여 운전자의 주의를 환기시키는 전방추돌 방지시스템이 대표적이다.As an example of the pre-safety device, the distance between the own vehicle and the preceding vehicle is calculated by emitting a radio wave such as a laser toward the front of the own vehicle, and measuring the time until the emitted radio wave returns to the reflector attached to the rear of the preceding vehicle and returns. In this case, the collision risk is predicted by substituting the calculated distance into the absolute speed of the host vehicle, and when there is a risk of collision, the front collision prevention system that alerts the driver to alert the driver is representative.

사후안전장치의 예로는 잘 알려진 바와 같은 안전벨트나 에어백 시스템이 대표적이다.Examples of post-safety devices are safety belts or airbag systems as are well known.

한편, 차량이 중앙선을 침범하여 충돌하는 경우에는 대부분 정면 충돌을 하게 되므로 추돌사고에 비하여 치명적인 인사 사고가 발생할 확률이 대단히 높다. 그러나, 종래에는 단지 추돌방지 시스템이나 사후 안전장치만 제안되어 있을 뿐이고 자차가 중앙선을 침범한 것을 감지하여 경보하는 장치가 개발되어 있지 않아서 운전자의 안전 확보가 미흡하다고 하는 문제점이 있었다.On the other hand, when a vehicle invades the center line and collides, most of the frontal collisions have a high probability of fatal personnel accidents compared to a collision accident. However, in the related art, only a collision avoidance system and a post-safety device have been proposed, and there is a problem that the driver's safety is not secured because a device for detecting and warning that the vehicle invades the center line has not been developed.

본 고안은 전술한 문제점을 해결하기 위하여 안출된 것으로서, 차량의 적소에 컬러 디지탈 카메라를 설치하여 자차가 현재 중앙선을 침범하는 지를 감지하고, 중앙선 침범하는 경우에는 즉시 경보를 발하므로써 치명적인 안전 사고를 미연에 방지할 수 있도록 한 자동차의 중앙선 침범 경보 장치를 제공하는데 그 목적이 있다.The present invention has been devised to solve the above-mentioned problems, by installing a color digital camera in place of the vehicle to detect whether the vehicle is currently invading the centerline, and in the event of a centerline violation, an immediate alarm is not provided. The purpose of the present invention is to provide a vehicle's central line intrusion alarm device to prevent.

전술한 목적을 달성하기 위한 본 고안의 자동차의 중앙선 침범 경보 장치는 크게 차선의 존재 및 색상을 감지하는 차선 감지부, 차선 감지부에서 감지된 신호를 처리하여 차선의 존재 여부 및 색상을 판단하고, 이를 중앙선의 색상에 대한 기준 신호와 비교하여 중앙선 여부를 판정하는 중앙선 판정부, 자차가 중앙선을 침범했음을 운전자에게 경보하는 경보 발생부 및 중앙선 판정부에서 제공된 신호에 따라 경보 발생부를 제어하는 제어부로 이루어진다.In order to achieve the above-mentioned object, a vehicle centerline invasion alarm device of the present invention largely determines a lane presence and color by processing a signal detected by a lane detection unit and a lane detection unit that detect the presence and color of a lane, It is composed of a center line judging unit for judging whether the center line is compared with the reference signal for the color of the center line, an alarm generating unit for alerting the driver that the host vehicle has invaded the center line, and a control unit for controlling the alarm generating unit according to a signal provided from the center line judging unit. .

The color input unit 30 is given to set and input the color of the center line. The color input unit 30 is provided to set and input the color of the center line when the color of the center line is different for each country. The center line determiner 40 detects the lane detection unit 20 and then provides a digital signal provided by the color input unit 30 separately from the three primary colors of R (Red), G (Green), and B (Blue). It is determined whether the center line is compared with the reference signal. The alarm generator 50 is preferably implemented as a buzzer or the like.

도 2는 본 고안에 따른 차선 감지 센서를 자동차에 장착한 상태를 개략적으로 보인 투시도이다. 도 2에 도시한 바와 같이, 본 고안에 따른 차선 감지 센서 즉 디지탈 카메라의 렌즈(21)는 차체 프레임(60)의 좌측 하부의 적소, 예를 들어 전방 좌측 차륜(21)의 직전방에 노면과 대향하도록 장착될 수 있다.2 is a perspective view schematically showing a state in which a lane detecting sensor according to the present invention is mounted on a vehicle. As shown in FIG. 2, the lane detection sensor according to the present invention, that is, the lens 21 of the digital camera, has a road surface in front of the left lower part of the body frame 60, for example, in front of the front left wheel 21. Can be mounted to face each other.

이하에는 본 고안의 자동차의 중앙선 침범 경보 장치의 동작에 대해서 상세하게 설명한다.Hereinafter will be described in detail the operation of the center line intrusion alarm device of the vehicle of the present invention.

먼저, 본 고안의 장치가 동작하기 위해서는 색상 입력부(30)를 조작하여 중앙선의 기준 색상, 예를 들어 한국의 경우에는 황색을 입력해야 하는데, 이렇게 입력된 색상은 이후에 중앙선 판정부(40)에 제공되어 차선 감지부(20)에서 감지된 차선의 색상과 비교되게 된다. 즉, 중앙선 판정부(40)에서는 차선 감지부(20)에서 감지된 후에 R(Red), G(Green), B(Blue)의 삼원색 성분으로 분리되어 제공되는 디지탈 신호를 상기 색상 입력부(30)에서 제공된 기준 색상에 대응되는 신호와 비교하여 중앙선 여부를 판정한 후에 그 결과를 제어부(10)에 전달한다. 다음, 제어부(10)에서는 상기 중앙선 판정부(40)에서 판정한 결과에 따라 경보 발생부(50)를 제어하는데, 예를 들어 중앙선 판정부(40)에서 판정한 차선이 중앙선이 아닌 경우에는 제어부(10)에서는 경보 발생부(50)를 제어하여 경보가 발생되지 않도록 한다. 반면에, 중앙선 판정부(40)에서 판정한 차선이 중앙선, 즉 황색인 경우에는 경보 발생부(50)를 제어하여 즉시 경보가 발생하도록 한다.First, in order for the device of the present invention to operate, the color input unit 30 is operated to input a reference color of the center line, for example, yellow in the case of Korea, which is then input to the center line determination unit 40. It is provided to be compared with the color of the lane detected by the lane detection unit 20. That is, in the center line determiner 40, the color input unit 30 receives a digital signal provided after being detected by the lane detector 20 and separated into three primary color components of R (Red), G (Green), and B (Blue). After determining whether the center line is compared with the signal corresponding to the reference color provided by the and transmits the result to the controller 10. Next, the control unit 10 controls the alarm generating unit 50 according to the result determined by the center line determining unit 40. For example, if the lane determined by the center line determining unit 40 is not the center line, In 10, the alarm generator 50 is controlled to prevent an alarm from occurring. On the other hand, when the lane determined by the center line determining unit 40 is a center line, that is, yellow, the alarm generating unit 50 is controlled to immediately generate an alarm.

본 고안에 따른 자동차의 중앙선 침범 경보 장치는 전술한 실시 예에 국한되지 않고, 본 고안의 기술사상이 허용하는 범위내에서 다양하게 변형하여 실시될 수가 있다.The centerline infringement warning apparatus for a vehicle according to the present invention is not limited to the above-described embodiment, and may be variously modified and implemented within the range permitted by the technical idea of the present invention.

이상에서 설명한 바와 같은 본 고안의 자동차의 중앙선 침범 경보 장치에 따르면, 차량의 적소에 컬러 디지탈 카메라를 설치하여 자차가 현재 중앙선을 침범하는 지를 감지하고, 중앙선 침범하는 경우에는 즉시 경보를 발하므로써 치명적인 안전 사고를 미연에 방지할 수 있는 효과가 있다.According to the centerline invasion alarm device of the vehicle of the present invention as described above, by installing a color digital camera in the right place of the vehicle to detect whether the vehicle is currently invading the centerline, and in the event of a centerline invasion, a fatal safety There is an effect that can prevent accidents in advance.
