Description
본 발명은 자동차의 주행중에 자동차의 전방에 위치한 장애물의 존재를 운전자에게 알려줄 수 있도록 하는 자동차의 주행중 노면상태 경고장치에 관한 것으로, 더 자세하게는 주행중인 자동차 전방의 노면상태가 나쁠 경우에 운전자가 안전하게 그 부위를 통과할 수 있도록 사전 경보음이나 안내음 성신호를 발생시키는 것에 관한 것이다.The present invention relates to a road warning state during driving of a vehicle that enables the driver to be notified of the presence of an obstacle located in front of the vehicle while driving the vehicle, and more particularly, when the road condition in front of the driving vehicle is bad. It is about generating a pre-alert or guide sound to pass through the area.
일반적으로 자동차를 주행함에 있어서는 전방의주행 노면에 돌이나 움푹 패인 구덩이, 과속방지턱 등의 장애물에 나타날 수 있게 되는 바, 운전자가 이러한 돌발적인 장애물을 정확하게 인지한 경우에는 자동차의 속도를 적절하게 줄여 안전하게 통과할 수 있게 되지만 장애물을 존재를 인지하지 못하고 무심하게 지나다보면 자동차가 전체적으로 충격을 받게 되어 완충댐퍼를 포함한 현가장치의 수명이 크게 단축될 뿐 아니라 자체가 장애물과 접촉하게 되어 많은 손상을 입게 된다.In general, when driving a car, it may appear on obstacles such as stones, potholes, speed bumps, etc. on the road ahead, and if the driver recognizes such an unexpected obstacle accurately, the speed of the car is appropriately reduced. Although it is possible to pass through obstacles without knowing the existence of obstacles, the car is shocked as a whole, which greatly shortens the lifespan of the suspension system including the shock absorber, and also causes a lot of damage by contacting the obstacle itself.
또한 상기 장애물을 미리 대비함 없이 무심코 지날 때의 갑작스러운 충격은 운전자는 물론 자동차의 내부에 탑승한 각 승객에 심리적인 불안감을 줄 뿐 아니라 충격이 심한 경우에는 승객의 부상을 입게 되는 등 각종 안전사고까지 초래하게 된다.In addition, the sudden impact of accidentally passing the obstacle without prior preparation not only gives the driver psychological anxiety to each passenger in the interior of the vehicle, but also injuries of the passengers in case of severe impact. Will result in.
본 발명은 상기 종래의 실정을 감안하여 안출한 것이며, 그 목적은 주행중인 자동차의 전방 노면에 나타나는 장애물의 존재를 운전자에게 화면이나 경보음 등으로 알려줌으로써 운전자가 장애물에 대해 안전하게 대처할 수 있도록 하는 자동차의 주행중 노면상태 경고장치를 제공하는 데에 있는 것이다.The present invention has been made in view of the above-described conventional situation, and its object is to inform the driver of the presence of an obstacle appearing on the road surface in front of the vehicle being driven by a screen or an alarm sound so that the driver can cope with the obstacle safely. It is to provide a road surface warning device while driving.
제1도는 본 발명의 관계하는 자동차의 측면도.1 is a side view of a motor vehicle in accordance with the present invention.
제2도는 본 발명의 구성 블록도.2 is a block diagram of the present invention.

본 발명은 상기의 목적을 달성하기 위하여 자동차의 전방범퍼에 장애물을 존재를 식별할 수 있도록 하는 카메라센서를 설치하고, 이 카메라센서에서 엔진콘크롤유니트로 입력되는 신호를 제어하여 경보음이나 음성신호로 운전자에게 전달할 수 있도록 하는 것을 특징으로 하며, 이하 그 구체적인 내용을 첨부도면에 의거하여 더욱 자세히 설명하면 다음과 같다.The present invention is to install a camera sensor to identify the presence of obstacles in the front bumper of the vehicle in order to achieve the above object, by controlling the signal input to the engine control unit from the camera sensor alarm sound or voice signal It is characterized in that it can be delivered to the driver as described below, in more detail based on the accompanying drawings as follows.
즉, 본 발명은 제1도 및 제2도와 같이 자동차(1)의 전방범퍼(2)의 좌우 양측에 카메라센서(3)를 설치하고, 이 카메라센서(3)와 속도센서(4)를 엔진콘트롤유니트(5)의 입력측에 접속하는 한편 엔진콘트롤유니트(5)의 출력측에 경보수단(6)을 접속하여서 되는 것이다.That is, according to the present invention, the camera sensors 3 are installed on both the left and right sides of the front bumper 2 of the vehicle 1, as shown in FIGS. 1 and 2, and the camera sensor 3 and the speed sensor 4 are engines. The alarm means 6 is connected to the input side of the control unit 5 and to the output side of the engine control unit 5.
상기에서 경보수단(6)은 스피커를 포함하는 것으로, 본 발명에 있어서 경보수단(6)을 통한 경고는 엔진콘트롤유니트(5)에 “전방 왼쪽(오른쪽, 중앙)에 장애물 조심”이라든지 그 밖의 음성신호를 녹음해 놓은 후 카메라센서(3)의 입력신호에 따라 선택적으로 운전자에게 전달하는 방식이나 “삐-, 삐-, 삐-”등의 일반 경보음을 발생하는 방식, 경보 등을 점등하는 방식 등 예측가능한 방식을 사용할 수 있음은 물론이며, 경우에 따라서는 둘 이상의 경보방식을 채용할 수도 있다.In the above, the alarm means 6 includes a speaker. In the present invention, the warning means through the alarm means 6 means that the engine control unit 5 is “obstructed at the front left (right, center) and other voices”. Record the signal and then selectively transmit it to the driver according to the input signal from the camera sensor (3), generate a general alarm sound such as “beep, beep, beep”, and light up the alarm. Of course, a predictable method may be used, and in some cases, two or more alarm methods may be employed.
또한 상기 엔진콘트롤유니트(5)는 입력단의 카메라센서(3)에서 출력한 차량 전망측의 노면상태에 대한 전기적인 신호를 입력하여 운전자 전방의 화면출력수단에 노면상태를 운전자가 알 수 있도록 출력하는 것이다.In addition, the engine control unit 5 inputs an electrical signal for the road surface state of the vehicle view side output from the camera sensor 3 of the input stage to output the road surface so that the driver knows the road state to the screen output means in front of the driver. will be.
여기서 화면출력수단은 운전자가 눈으로 확인할 수 있는 영상신호를 출력할 수 있는 것으로 흑백 영상이나 칼라영상 등을 출력할 수 있는 모니터이다.Here, the screen output means is a monitor capable of outputting a video signal that the driver can visually check, and can output a black and white image or a color image.
한편 본 발명에 있어서는 속도센서(4)의 입력신호를 통해 장애물에 도달하기까지의 시간을 연산한 후 사전에 노면상태를 경고함으로써 운전자가 충분히 대처할 수 있는 시간적 여유를 주게 된다.(예컨데 장애물 도달 23초 전에 경고)On the other hand, in the present invention, after calculating the time to reach the obstacle through the input signal of the speed sensor 4, and warns the road surface condition in advance, it gives the driver enough time to cope with sufficiently. Alert 3 seconds ago)
상기에서 장애물 도달시간(t)은 장애물까지의 거리(s)를 현재 주행속도(v)로 나누면 된다.(t=s/v)The obstacle arrival time t is obtained by dividing the distance s to the obstacle by the current traveling speed v. (T = s / v)
이상에서와 같이 본 발명은 주행중인 자동차의 전방 노면상태를 감지하여 장애물이 있는 그 장애물에 도달하기 전에 운전자에게 장애물의 존재를 영상수단이나 음성출력수단을 통해 확실하게 알려줄 수 있게 한 것으로, 본 발명에 의하면 운전자가 장애물의 위치를 정확하게 파악하여 안전하게 지날 수 있게 되므로 현가장치의 수명을 크게 연장할 수 있게 되고, 차체의 손상을 방지할 수 있게 되며, 승객의 부상을 방지할 수 있게 되는 등 자동차의 안전성을 큭 향상시킬 수 있게 되는 효과를 얻을 수 있게 된다.As described above, the present invention is to detect the road surface state of the driving vehicle to ensure that the driver to know the existence of the obstacle through the video means or audio output means before reaching the obstacle with the obstacle, the present invention According to the present invention, the driver can pinpoint the location of obstacles and pass safely, thus greatly extending the life of the suspension system, preventing damage to the vehicle body, and preventing injuries of passengers. It is possible to obtain an effect that can greatly improve safety.
