본 발명은 후속차량의 안전거리미확보시 정지등자동구동장치에 관한 것으로, 특히 자동차후방의 소정위치에 후속차량과의 거리를 감지하는 거리감지센서를 설치하여 후속차량이 안전거리범위내로 진입하였을 경우 정지등이 자동으로 작동하도록 된 후속차량의 안전거리미확보시 정지등자동구동장치에 관한 것이다.The present invention relates to a stop light automatic driving device when the safety distance of the subsequent vehicle is not secured. In particular, when a subsequent vehicle enters the safety distance range by installing a distance sensor to detect a distance to the next vehicle at a predetermined position in the rear of the vehicle. The present invention relates to an automatic stop light driving device when the safety distance of a subsequent vehicle is not secured so that the stop light operates automatically.
현재, 제품화되어 판매되고 있는 차량의 전단과 후단에는 방향표시등과 정지등이 설치되어 있는 바, 방향표시등은 차량의 진행방향을 표시할 뿐만 아니라 차량의 전면제어패널 또는 핸들자체에 부착된 비상등레버의 조정에 의하여 점멸되어 후속차량의 운전자에게 차량의 이상 또는 안전운전에 대한 비상사태 등의 발생 등을 알려주는 작용을 하고, 정지등은 운전자의 브레이크조작에 의해 자동으로 점등되어 후속차량의 운전자에게 현재 제동중임을 알리는 기능을 수행한다.At present, commercialized and sold vehicles are equipped with direction indicators and stop lights at the front and rear ends of the vehicle, and the direction indicators not only indicate the direction of the vehicle, but also the front of the vehicle control panel or the steering wheel itself. It blinks by adjustment and informs the driver of the next vehicle about the occurrence of an abnormality in the vehicle or the safe driving, and the stop light is automatically turned on by the driver's brake operation to present the driver of the next vehicle. It performs the function to inform that it is braking.
따라서, 국도나 고속도로상에서 고속주행 중에 급제동이 이루어지면 정지등이 자동으로 점등되어 후속차량에게 현재 제동중임을 알려주게 된다.Therefore, if a rapid braking is made during high-speed driving on a national road or a highway, the stop light is automatically turned on to inform subsequent vehicles that they are currently braking.
그러나, 선행차량은 안전속도(규정속도)를 유지한 채 주행하고 있는데 후속차량이 안전속도 이상의 가속으로 선행차량을 뒤따라오는 경우 선행차량의 운전자는 방어운전의 일환으로서 브레이크조작을 하여 정지등을 점등시켜 후속차량의 운전자에게 경각심을 일깨워주게 되므로 인위적인 브레이크조작을 해야되는 불편함이 발생하게 되고, 대부분의 선행차량의 운전자는 거의 전방 및 옆차선의 차량주행상태에 대해서만 신경쓰면서 주행하므로 후속차량의 주행상태를 똑바로 관찰하지 않기 때문에 후속차량의 가속상태를 인식하지 않는 상태에서 전방에 돌출사고가 발생하여 급제동하였을 경우 차량의 후단에 설치된 정지등이 점등되지만 후속차량의 안전거리미확보로 인하여 추돌사고를 일으키게 될 뿐만 아니라 그 추돌사고로 인하여 주행차선을 벗어남에 따라 마주 오는 대형차와 충돌사고를 일으키는 2차 사고가 발생된다.However, when the preceding vehicle is running at a safe speed (regulated speed) and the following vehicle follows the preceding vehicle with an acceleration above the safe speed, the driver of the preceding vehicle brakes as part of the defensive driving and turns on the stop light. This causes the driver of the following vehicle to be alerted, causing inconvenience to man-made brake operation, and most of the driver of the preceding vehicle travels with only caring about the driving conditions of the front and side lanes. If you do not observe the state of the vehicle upright and suddenly braking due to a sudden accident in front of the vehicle without recognizing the acceleration state of the following vehicle, the stop light installed at the rear of the vehicle will be lit, but it will cause a collision accident due to the inability to secure the safety distance of the following vehicle.

일단, 제 2 도의 단계 200에서 차속검출부(12)는 브레이크(10)조작으로 인한 급감속되는 차속 또는 현재 주행중인 차량(A)의 차속을 검출하게 된다. 이어, 단계 210에서 제어부(18)는 그 차속검출부(12)에서 검출된 차속에 해당하는 후속차량(B)의 안전거리를 기준안전거리데이타기억부(14)에서 검출함과 동시에 그 검출된 안전거리범위를 방사할 수 있는 광량조절신호를 출력하게 되고, 단계 220에서 거리감지부(16)의 적외선발광소자(16a)는 그 광량조절신호에 따라 적외선을 방사하게 된다. 이어, 단계 230에서 제어부(18)에서는 적외선수광소자(16b)에 수광되는 적외선이 있는지를 판단하게 되는 바, 수광되는 적외선이 없는 경우 제어부(18)는 안전거리내로 후속차량(B)이 진입하지 않은 것으로 판단하여 상기 단계 220을 반복수행하도록 하는 반면, 수광되는 적외선이 있는 경우 단계 240에서 상기 제어부(18)는 후속차량(B)이 안전거리범위내로 진입하였다고 판단하게 되므로 그에 따른 경고발생신호를 출력하게 된다. 그후, 단계 250에서 정지등구동부(20)는 그 제어부(18)에서 출력되는 경고발생신호에 따라 정지등구동신호를 출력하게 된다. 그후, 단계 250에서 정지등구동부(20)는 그 제어부(18)에서 출력되는 경고발생신호에 따라 정지등구동신호를 출력하므로 정지등(22)이 자동으로 점등되어 후속차량(B)의 운전자는 그 선행차량(A)의 점등되는 정지등(22)을 보고 상기 선행차량(A)이 감속주행중임을 알게 되거나 자신의 차량(B)이 가속주행중임을 인식하여 감속주행을 하게 된다.First, in step 200 of FIG. 2, the vehicle speed detection unit 12 detects a rapidly decelerated vehicle speed or a vehicle speed of a vehicle A currently being driven due to the operation of the brake 10. Subsequently, in step 210, the control unit 18 detects the safety distance of the subsequent vehicle B corresponding to the vehicle speed detected by the vehicle speed detection unit 12 in the reference safety distance data storage unit 14, and simultaneously detects the safety distance. A light amount control signal capable of emitting a distance range is output, and in step 220, the infrared light emitting element 16a of the distance sensing unit 16 emits infrared light according to the light amount control signal. Subsequently, in step 230, the controller 18 determines whether there is infrared light received by the infrared light receiving element 16b. When there is no infrared light received, the controller 18 does not enter a subsequent vehicle B within a safety distance. In step 240, the controller 18 determines that the subsequent vehicle B has entered the safety distance range. Will print. Thereafter, in step 250, the stop light driving unit 20 outputs a stop light driving signal according to the warning generation signal output from the control unit 18. Then, in step 250, the stop light driving unit 20 outputs a stop light driving signal according to the warning signal output from the control unit 18, so that the stop light 22 is automatically turned on so that the driver of the subsequent vehicle B By looking at the stop light 22 of the preceding vehicle A is turned on to know that the preceding vehicle A is decelerating, or recognizes that the vehicle B is being accelerated, the vehicle decelerates.
상기와 같이 구성된 본 발명에 따른 후속차량의 안전거리미확보시 정지등자동구동장치에 의하면 국도나 고속도로상에서 후속차량이 안전거리를 무시한 채 가속으로 뒤따라오고 있는 경우 인위적으로 브레이크조작을 하여 정지등이 점등되도록 하는 종래의 방식과는 달리 거리감지센서에서 감지되는 감지신호에 의해 자동으로 정지등이 점등되므로 종래의 브레이크조작을 해야 되는 불편함이 해소될 뿐만 아니라 후속차량의 주행상태에 신경을 쓰지 않아도 되므로 훨씬 여유있는 운전을 할 수 있게 된다.According to the stop light automatic driving device when the safety distance of the subsequent vehicle according to the present invention configured as described above is secured when the subsequent vehicle follows the acceleration while ignoring the safety distance on a national road or a highway, the stop light is turned on by artificially operating the brake. Unlike the conventional method, the stop light is automatically turned on by the detection signal detected by the distance sensor, so that the inconvenience of the conventional brake operation is eliminated and the car does not have to worry about the driving state of the subsequent vehicle. You will be able to drive much more relaxedly.
