Description

안전거리를 유지하기 위한 경고단계 표시장치Warning level indicator to maintain safety distance

본 고안은 안전거리를 유지하기 위한 경고단계 표시장치에 관한 것으로서, 보다 상세하게는 자동차를 운행하는 과정에서 선행차의 후방으로 전파를 송출하여 송출된 신호에 의해 감지되는 거리값으로 운행속도를 감지하고,이 감지된 운행속도에 대한 거리로 후방차량과 안전거리미확보의 단계를 판별하여 판별된 신호로 위험정도에 따라 램프의 점멸주기를 조절하여 후방차량의 운전자에게 위험정도를 표시하도록 한 안전거리를 유지하기 위한 경고단계 표시장치에 관한 것이다.The present invention relates to a warning level display device for maintaining a safe distance, and more particularly, to detect the driving speed by the distance value detected by the signal transmitted by transmitting a radio wave to the rear of the preceding vehicle in the course of driving the car. The distance of the detected vehicle speed is determined by determining the level of the rear vehicle and the non-safety distance, and by using the determined signal, the flashing period of the lamp is adjusted according to the degree of danger to indicate the degree of danger to the driver of the rear vehicle. Warning step for maintaining the display device.

일반적으로 자동차에는 배터리전원에 점소등되는 램프가 구비되고, 각 램프의 기능에 따라 운전자가 램프를 점등시키는 각 스위치접점을 브레이크상태로 변환하여 변환된 접점으로 배터리전원이 공급된다. 따라서, 전후방의 운전자들에게 자동차의 진행방향(방향지시등), 현재상태(비상등), 감속 및 제동등(브레이크등) 등의 램프를 점등시키게 되는 조명장치가 구비되고, 상기 조명장치를 점소등시키는 스위치의 접점에 의해 자동차를 운행하는 과정에서 현재상태를 각 램프를 점등시켜 선후방의 운전자에게 알리게 되는 것이다.In general, a vehicle is provided with a lamp that is turned on and off the battery power, and according to the function of each lamp, the battery power is supplied to the converted contact by converting each switch contact for the driver to turn on the lamp to the brake state. Therefore, the front and rear drivers are provided with a lighting device which lights the lamps such as the driving direction (direction indicator), the current state (emergency lamp), the deceleration and the braking lamp (brake lamp), etc., and switches on and off the lighting device. In the process of driving a car by the contact of the lamp, each lamp is turned on to inform the driver behind the ship.

이와 같이 자동차의 후방에 설치된 조명장치에는 자동차를 운행하는 과정에서 감속이나 제동을 하기 위해 브레이크페달을 밟게 될 때 페달스위치의 접점이 브레이크상태가 되어 브레이크등이 점등되고, 선행차의 감속을 표시하게 된다. 상기 브레이크등이 점등되는 경우에는 후방차량의 운전자에게 선행차가 감속 또는 정지하기 위해 속도를 감속함을 표시하게 되므로, 후방차량의 속도를 감속하기 위해 브레이크등을 점등시켜 후방차량과 추돌사고를 방지하는 역할을 겸하게 되는 램프인 것이다.In this way, when the brake pedal is pressed to decelerate or brake the vehicle in the process of driving the vehicle, the contact point of the pedal switch is in a brake state so that the brake light is turned on and the deceleration of the preceding vehicle is displayed. do. When the brake light is turned on, the driver of the rear vehicle shows that the preceding vehicle decelerates in order to reduce or stop the vehicle. Thus, the brake vehicle is turned on to reduce the speed of the rear vehicle, thereby preventing a collision with the rear vehicle. It is a lamp that also serves as a role.

그러나, 이와 같이 자동차의 후미에 설치된 브레이크등에 의하여 후방차량으로 하여금 선행차가 정지하려 하거나 감속함을 알려주기 위해 브레이크페달을 밝게 되나 안전거리를 무시한 후방차량이 있고, 선행차의 사정에 의해 갑작스럽게 정지를 하게 되는 경우에는 아무리 선행차가 정지하기 위해 브레이크페달을 밟는다 하더라도(브레이크등이 자동점등되어 후방의 운전자에게 선행차의 정지상태 혹은 속도를 늦추고 있음을 경고하고 있으나) 안전거리를 확보하지 않은 후방차량으로서는 브레이크를 밟았다 하더라도 이미 달리는 속도에 의해 선행차와 추돌할 수 밖에 없는 문제점을 내포하게 된다.However, the brake pedal lights up to inform the rear vehicle that the preceding vehicle is about to stop or decelerate by the brake lights installed at the rear of the vehicle. However, there is a rear vehicle that ignores the safety distance and suddenly stops due to the circumstances of the preceding vehicle. However, even if the brake pedal is applied to stop the preceding vehicle (the brake light is automatically turned on to warn the driver behind the vehicle to stop or slow down), the rear vehicle without securing a safety distance Even if the brakes are applied, there is a problem that they have to collide with the preceding vehicle by the speed at which they are already running.

따라서, 선행차와의 안전거리를 유지하기 위해 후방차량의 운전자에게 경고할 수 있는 경고장치를 필요로 하게 되었다.Therefore, there is a need for a warning device that can warn the driver of the rear vehicle to maintain a safe distance from the preceding vehicle.

이에 본 고안은 상기와 같은 문제점을 고려하여 안출된 것으로서, 그 목적은 자동차를 운행하는 과정에서 선행차의 후방으로 전파를 송출하여 송출된 신호에 의해 감지되는 거리값으로 운행속도를 감지하고,이 감지된 운행속도에 대한 거리로 후방차량과 안전거리미확보의 단계를 판별하여 판별된 신호로 위험정도에 따라 램프의 점멸주기를 조절하여 후방차량의 운전자에게 위험정도를 표시하도록 한 안전거리를 유기하기 위한 경고단계 표시장치를 제공함에 있다.The present invention is conceived in consideration of the above problems, the purpose is to send a radio wave to the rear of the preceding vehicle in the course of driving the vehicle to detect the driving speed by the distance value detected by the transmitted signal, To determine the level of the rear vehicle and the non-safety distance based on the detected driving speed, and to control the flashing cycle of the lamp according to the degree of danger by using the signal determined to induce the safety distance to indicate the degree of danger to the driver of the rear vehicle. It is to provide a warning step display device for.

이러한 본 고안의 목적은, 자동차를 운행하는 과정에서 선행차와 후방차량의 안전거리가 확보되지 않으면 경고하는 경고단계 표시장치에 있어서, 후방으로 전파를 송출하여 송출된 신호로 선행차와 후방차량의 거리를 감지하는 거리감지센서와; 상기 후방차량의 차속을 감지하는 후방차량차속감지센서와; 상기 거리감지센서와 후방차량차속감지센서에서 출력된 신호로 배터리전원의 공급이 제한되도록 제어신호를 출력하는 제 1출력포트와, 거리에 대한 속도에 의해 위험정도의 단계에 따라 출력신호의 전류량을 제어하는 제 2출력포트를 갖는 컨트롤부와; 상기 컨트롤부의 제 1출력포트에서로부터 출력된 신호에 의해 배터리전원을 스위칭하는 스위칭소자와; 상기 스위칭소자에 의해 스위칭된 배터리전원와 컨트롤부의 제 2출력포트에서 출력된 신호에 의해 펄스신호의 주기를 따르게 출력하는 피리어드릴레이부와; 상기 피리어드릴레이부에서 출력된 펄스신호에 의해 외부로 경고램프를 점멸시키는 경고표시수단을 포함하여 이루어진 안전거리를 유지하기 위한 경고단계 표시장치에 의해서 달성될 수 있다.The object of the present invention is a warning step display device for warning if the safety distance between the preceding vehicle and the rear vehicle is not secured in the course of driving the vehicle, by transmitting a radio wave to the rear of the preceding vehicle and the rear vehicle A distance sensor for detecting a distance; A rear vehicle speed sensor for detecting a vehicle speed of the rear vehicle; A first output port for outputting a control signal to limit the supply of battery power to the signals output from the distance sensor and the rear vehicle speed sensor, and the current amount of the output signal according to the level of danger by the speed with respect to the distance.

첨부도면, 도 1은 본 고안에 따른 안전거리를 유지하기 위한 경고단계 표시장치의 구성을 보인 회로도이다. 도 1을 살펴보면, 자동차를 운행하는 과정에서 후방으로 전파를 송출하여 송출된 신호로 후방차량과의 거리를 감지하는 거리감지센서(10)로, 후방차량과의 거리를 감지하고, 감지된 신호는 컨트롤부(30)에 입력된다.1 is a circuit diagram showing a configuration of a warning step display device for maintaining a safe distance according to the present invention. Referring to FIG. 1, a distance detection sensor 10 that detects a distance from a rear vehicle as a signal transmitted by transmitting an electric wave backward in a process of driving a vehicle, detects a distance from a rear vehicle, and the detected signal is It is input to the control part 30.

또한, 후방차량의 속도를 감지하는 후방차량차속감지센서(20)로, 상기 거리감지센서(10)에서 감지된 거리신호에 대한 시간값으로 후방차량의 차속을 감지하며, 감지된 신호는 컨트롤부(30)에 입력된다.In addition, the rear vehicle vehicle speed sensor 20 for detecting the speed of the rear vehicle, and detects the vehicle speed of the rear vehicle as a time value for the distance signal detected by the distance sensor 10, the detected signal is a control unit It is input to 30.

상기 컨트롤부(30)은 거리감지센서(10)와 후방차량차속감지센서(20)에서 출력된 신호에 의해 후방차량과의 안전거리를 판별하게 되고, 판별된 신호에 따라 출력신호를 제어하게 된다. 즉, 선행차의 후방으로 전파를 송출하여 송출된 신호로 후방차량과의 거리과의 거리가 50km일 때, 후방차량의 운행속도가 50km로 운행하게 될 때와, 100km로 운행하게 될 때와, 150km로 운행하게 될 때, 200km로 운행하게 될 때의 거리에 대한 속도를 컨트롤부(30)에서 비교판단하여 판단된 신호에 의해 배터리전원의 공급이 제한되는 제 1출력포트(32)와, 위험정도의 단계에 따라 출력신호의 전류량을 증가시키는 제 2출력포트(34)로 출력하게 된다.The control unit 30 determines the safety distance from the rear vehicle by the signal output from the distance sensor 10 and the rear vehicle speed sensor 20, and controls the output signal according to the determined signal. . That is, when the distance from the rear vehicle is 50km as the signal transmitted by transmitting the radio wave to the rear of the preceding vehicle, when the driving speed of the rear vehicle runs at 50km, when driving at 100km, and 150km The first output port 32, the supply of battery power is limited by the signal determined by comparing the speed with respect to the distance when the driving to 200km when the driving to 200km, when determined to drive the drive, and the degree of danger According to the step of outputting to the second output port 34 to increase the amount of current of the output signal.

따라서, 후방차량과의 안전거리가 유지되면 출력은 로우신호가 출력되고, 상기 후방차량과의 안전거리가 유지되지 않으면 출력은 하이신호가 출력된다. 상기 컨트롤부(30)의 제 1출력포트(32)는 스위칭소자(40)에 입력되고, 제 2출력포트(34)는 피리어드릴레이부(50)에 입력된다.Therefore, if the safety distance with the rear vehicle is maintained, the output is a low signal, and if the safety distance with the rear vehicle is not maintained, the output is a high signal. The first output port 32 of the control unit 30 is input to the switching element 40, the second output port 34 is input to the period drill lay unit 50.

상기 스위칭소자(40)는 컨트롤부(30)의 제 1출력포트(32)에서 출력된 하이신호일 때 배터리전원을 스위칭하도록 접점이 브레이크상태로 유지되고, 상기 브레이크접점에 의해 공급된 배터리전원은 피리어드릴레리부(50)에 입력된다.The switching element 40 has a contact in a brake state to switch the battery power when the high signal output from the first output port 32 of the control unit 30, the battery power supplied by the brake contact is period It is input to the relay unit 50.

상기 피리어드릴레이부(50)는 스위칭소자(40)에 의해 스위칭된 배터리전원과, 컨트롤부(30)의 제 2출력포트(34)에서 출력된 신호는 피리어드릴레이부(50)의 입력에서 합이되어 입력된다. 즉, 피리어드릴레이부(50)로 공급된 배터리전원과 제 2출력포트(34)에서 입력된 전류에 의해 피리어드릴레이부(50)의 입력신호가 증가된다. 따라서, 증가된 신호에 의해 피리어드릴레이부(50)의 접점은 브레이크 상태와 액티브 상태를 입력된 전류량에 의해 펄스주기가 제어되고, 제어된 펄스주기는 경고표시수단(60)에 입력된다.The period drilllay unit 50 has a battery power switched by the switching element 40 and the signal output from the second output port 34 of the control unit 30 is equal to the sum of the inputs of the period drilllay unit 50. Is entered. That is, the input signal of the period drill lay unit 50 is increased by the battery power supplied to the period drill lay unit 50 and the current input from the second output port 34. Therefore, by the increased signal, the pulse period is controlled by the amount of current inputted to the brake state and the active state of the contact point of the drill hole, and the controlled pulse period is input to the warning display means 60.

상기 경고표시수단(60)은 피리어드릴레이부(50)에서 제어된 신호에 따라 자동차의 후방에 설치된 제 1경고램프(62)가 점멸되어 후방차량의 운전자에게 안전거리 이내로 진입한 상태를 표시하게 된다. 또한, 인스트루먼트 패널 일측 계기판에 구비된 제 2표시램프(64)가 점멸되어 후방차량이 안전거리 이내로 진입한 상태를 표시하게 되고, 경고음을 송출하는 경고음송출부(66)를 작동시켜 운전자에게 경고음으로 알리게 된다. 즉, 후방차량의 운행속도에 대한 일정거리를 유지하게 못하게 되면 컨트롤부(30)는 거리에 대한 위험정도의 단계가 검출되고, 검출된 신호에 의해 전류량이 증가되어 제 2출력포트(32)로부터 출력되고, 출력된 신호에 따라 피리어드릴레이부(50)의 펄스주기 신호를 제어하게 되는 것이다.The warning display means 60 is flickering the first warning lamp 62 installed in the rear of the vehicle in accordance with the signal controlled by the period drill lay unit 50 to display the state entered within the safety distance to the driver of the rear vehicle. . In addition, the second display lamp 64 provided on the instrument panel on one side of the instrument panel blinks to indicate a state in which the rear vehicle enters the safety distance, and operates a warning sound transmitting unit 66 that emits a warning sound as a warning sound to the driver. You will be notified. That is, when it is impossible to maintain a certain distance with respect to the driving speed of the rear vehicle, the control unit 30 detects a step of a risk level for the distance, and the amount of current is increased by the detected signal so that the second output port 32 The pulse period signal of the period drill lay unit 50 is controlled according to the output signal.

한편, 상기 경고표시수단(40)을 브레이크등(안전거리미확보등)을 이용하여 피리어드릴레이부(30)의 출력에 의해 점멸시키게 되면, 후방의 운전자에게 브레이크등과 구별되게 사용할 수 있으며, 거리감지센서(10)와 후방차량차속감지센서(20)에서 출력된 신호에 의해 후방차량의 속도에 따라 안전거리를 판별하게 되고, 이 판별된 신호로 브레이크등이 점멸되어 후방차량의 운전자에게 안전거리미확보 경고하게 되는 것이다.On the other hand, if the warning display means 40 flashes by the output of the period drill lay unit 30 by using a brake light (not secured safety distance), it can be used to distinguish the brake light to the driver of the rear, the distance detection The safety distance is determined according to the speed of the rear vehicle by the signal output from the sensor 10 and the rear vehicle vehicle speed sensor 20, and the brake lamp flashes by the determined signal to secure the safety distance to the driver of the rear vehicle. You will be warned.

이와 같은, 구성을 갖는 본 고안의 작용은 자동차를 운행하는 과정에서 후방차량이 선행차와 일정거리를 유지하지 아니하고, 운전하게 될 때 선행차의 후방에서 전파를 송출하여 송출된 신호에 의해 후방차량과의 거리를 감지하는 거리감지센서(10)와, 후방차량의 차속을 감지하는 후방차량차속감지센서(20)에서 거리신호에 대한 시간값으로 후방차량의 차속이 감지된다.As described above, the operation of the present invention having the configuration does not maintain a certain distance with the preceding vehicle in the course of driving the vehicle, and when driving, the rear vehicle is transmitted by transmitting a radio wave from the rear of the preceding vehicle. The vehicle speed of the rear vehicle is detected as a time value for the distance signal from the distance sensor 10 for detecting the distance between the vehicle and the rear vehicle vehicle speed sensor 20 for detecting the vehicle speed of the rear vehicle.
