Description
본 발명은 안전 장치에 관한 것으로서, 보다 상세하게는 자동차의 신호 대기 시 안전 장치에 관한 것이다.The present invention relates to a safety device, and more particularly, to a safety device when waiting for a signal of a vehicle.
일반적으로, 자동차를 운행하게 되면 도로상의 신호에 따라 주행하게 되는 바, 교차로등에 설치된 신호등의 지시에 따라 차량이 운행하게 되는 것이다.In general, when a car is driven, the vehicle is driven according to a signal on a road, and the vehicle is driven according to an instruction of a traffic light installed at an intersection.
즉, 통상의 4색 신호등에 따라 녹색이면 진행, 적색이면 정지, 황색이면 대기, 화살표 신호이면 신호에 따라 진행하게 되는 것이다.That is, according to the conventional four-color traffic light, if the green, the progress is red, the stop, the yellow is waiting, if the arrow signal is to proceed according to the signal.
여기서, 상기한 교차로등에서 황색 또는 적색이면 차량이 정지선에서 정지한 상태로 대기하게 되고, 상기한 신호등이 녹색 또는 화살표로 변경되면 진행하게 되는 것이다.Here, when the intersection light is yellow or red, the vehicle waits in a stopped state at the stop line, and when the traffic light changes to green or arrow, the vehicle proceeds.
물론, 상기한 정지선에서 정지 시 운전자는 브레이크 페달을 밟거나 주차 브레이크를 동작시킨 상태로 대기하게 된다.Of course, when the driver stops at the stop line, the driver waits while pressing the brake pedal or operating the parking brake.
그러나, 상기한 바와 같이 교차로 정지 시 운전자가 브레이크 페달 또는 주차 브레이크를 동작시킬 때 브레이크 페달을 약하게 밟거나 평지에서는 밟지 않고, 주차 브레이크도 동작시키지 않은 상태에서 정지하고 있기 때문에 후방 차량 추돌 시 연쇄 충돌이 발생되는 문제점이 있다.However, as described above, when the driver operates the brake pedal or the parking brake at the intersection stop, the driver does not step on the brake pedal weakly or on the flat surface and stops the parking brake. There is a problem that occurs.
따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 교차로에서 황색 또는 적색 신호에서 정지 시 운전자가 브레이크를 밟지 않아 발생되는 연쇄 충돌을 방지할 수 있는 자동차용 안전 장치를 제공함에 있다.Accordingly, an object of the present invention to solve the above problems, to provide a safety device for a vehicle that can prevent a chain collision caused by the driver does not press the brake when the stop at the yellow or red signal at the intersection.

상기한 목적을 실현하기 위하여 본 발명은 차량 정지 시 교차로 신호등의 색 신호를 판별하여 적색 또는 황색 신호일 경우 브레이크를 동작시키고 녹색 신호일 경우 브레이크를 해제시키도록 구성된 제한 수단을 브레이크 페달에 연결 설치하여 구성함을 특징으로 한다.In order to realize the above object, the present invention is configured by connecting to the brake pedal a limiting means configured to determine the color signal of the intersection traffic light when the vehicle is stopped, to operate the brake when the red or yellow signal, and to release the brake when the green signal. It is characterized by.
도면은 본 발명에 따른 자동차용 안전 장치를 도시한 개략도로서, 차속 센서(SS)가 차속을 정지 상태로 판별할 때 교차로 신호등(S)의 색 신호를 판별하여 적색 또는 황색 신호일 경우 브레이크를 동작시키고 녹색 신호일 경우 브레이크를 해제시키도록 구성된 제한 수단이 브레이크 페달(P)에 연결 설치되어 있다.Figure is a schematic diagram showing a safety device for a vehicle according to the present invention, when the vehicle speed sensor (SS) determines the vehicle speed to the stop state to determine the color signal of the intersection traffic light (S) to operate the brake in the case of a red or yellow signal In the case of a green signal, a limiting means configured to release the brake is connected to the brake pedal P.
상기한 제한 수단은 신호등(S)의 색을 감지할 수 있도록 차량 외부에 설치된 카메라(1)등과 같은 감지 수단과, 상기한 카메라(1)에 연결되어 색 신호를 전달받는 ECU(2)와, 상기한 ECU(2)에 의해 제어됨과 아울러 상기한 적색 또는 황색 신호 감지 시 브레이크 페달(P)을 동작시키고 녹색 신호일 경우 해제시키도록 설치된 제동 수단으로 구성되어 있다.The limiting means includes a sensing means such as a camera 1 installed outside the vehicle so as to detect the color of the traffic light S, an ECU 2 connected to the camera 1 and receiving a color signal; In addition to the control by the ECU (2), the brake pedal (P) is activated when the detection of the red or yellow signal, and is provided with a braking means provided to release the green signal.
즉, 상기한 카메라(1)가 신호등의 색 신호를 감지한 후 이를 ECU(2)에 전달하게 되면 ECU(2)가 황색 또는 적색 신호일 때 브레이크를 자동 제동하게 됨으로써 후방 추돌시에도 연쇄 충돌을 방지할 수 있는 것이다.That is, when the camera 1 detects a color signal of a traffic light and transmits it to the ECU 2, the ECU 2 automatically brakes the brake when the ECU 2 is a yellow or red signal, thereby preventing a chain collision even in the rear crash. You can do it.
상기한 제동 수단은 브레이크 페달(P)에 연결됨과 아울러 ECU(2)에 전기적으로 연결된 솔레노이드(3)로 구성되어 있다.The braking means described above is composed of a solenoid 3 connected to the brake pedal P and electrically connected to the ECU 2.
상기한 바와 같은 본 발명의 작용 효과를 설명하면 운전자가 주행중 교차로에서 정지하게 되면 상기한 브레이크 페달(P)을 밟은 상태가 된다.Referring to the operation and effect of the present invention as described above, when the driver stops at the intersection while driving, the brake pedal P is in a state of being pressed.
이때, 상기한 교차로가 평지일 경우 운전자가 브레이크 페달(P)에서 발을 떼게 되는 바, 상기한 카메라(1)가 교차로 신호등(S)의 색을 감지하게 된다.In this case, when the intersection is flat, the driver releases the brake pedal P, and thus the camera 1 detects the color of the intersection traffic light S. FIG.
카메라(1)가 교차로 신호등(S)의 색을 감지하여 ECU(2)에 전달하게 되면 상기한 ECU(2)가 색 신호를 판별하게 된다.When the camera 1 detects the color of the intersection traffic light S and transmits the color to the ECU 2, the ECU 2 determines the color signal.
색 신호를 판별하여 황색 또는 적색일 경우 ECU(2)가 솔레노이드(3)에 전류를 공급하게 되고, 상기한 솔레노이드(3)를 동작되어 브레이크 페달(P)을 당기게 된다.When the color signal is determined to be yellow or red, the ECU 2 supplies current to the solenoid 3, and the solenoid 3 is operated to pull the brake pedal P. FIG.
브레이크 페달(P)이 당겨지게 되면 상기한 차량의 브레이크가 동작되면서 후방 추돌시에도 차량이 전방으로 밀리지 않도록 하는 것이다.When the brake pedal P is pulled, the brake of the vehicle is operated to prevent the vehicle from being pushed forward even in the rear crash.
물론, 상기한 색 신호가 녹색일 경우에는 ECU(2)가 솔레노이드(3)에 전류를 공급하지 않게 되고, 상기한 전류가 공급되지 않으면 브레이크 페달(P)이 작동되지 않게 됨으로서 운전자 의지대로 차량을 조종할 수 있게 된다.Of course, when the color signal is green, the ECU 2 does not supply current to the solenoid 3, and if the current is not supplied, the brake pedal P is not operated, thereby driving the vehicle at the driver's will. You can control it.
즉, 적색 또는 황색일 때는 자동적으로 브레이크 페달(P)이 작동하지만 녹색일 경우에는 작동하지 않게 되는 것이다.In other words, the brake pedal (P) is automatically activated when the red or yellow, but does not operate when the green.
상기한 바와 같이 교차로 신호등(S)의 색에 따라 차량의 브레이크를 제어하게 되면 교차로 후방 추돌 시 연쇄 충돌을 방지함과 아울러 교차로 급출발을 방지할 수 있게 된다.As described above, when the brake of the vehicle is controlled according to the color of the intersection traffic light S, it is possible to prevent the chain collision during the rear collision of the intersection and to prevent the rapid start of the intersection.
이상과 같이 본 발명은 교차로에서 차량 정지 시 적색 또는 황색 신호에서 자동적으로 차량 브레이크가 동작되도록 함으로써 후방 추돌 시 연쇄 충돌을 방지할 수 있는 잇점이 있는 것이다.As described above, the present invention has an advantage of preventing a chain collision during a rear collision by automatically operating a vehicle brake at a red or yellow signal when the vehicle is stopped at an intersection.
