본 발명의 실시예를 첨부도면에 의하여 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.
본 발명의 실시예는 후방 차량과 자기 차량 사이의 거리인 차간 거리(S1)를 검출하는 차간 거리 검출 수단(10)과; 자기 차량의 속도를 검출하는 차속 검출 수단(20)과; 상기 자기 차량의 운전자에게 후방 차량의 근접을 경고하는 운전석 경고부(31)와, 후방 차량의 운전자에게 앞 차량에게 근접하여 위험함을 경고하는 후방 차량 경고부(32)로 이루어진 근접 경고 수단(30)과; 자기 차량과 후방 차량의 속도차에 따른 주행 안정 거리인 기준 차간 거리(S)에 대한 데이터를 메모리에 저장하고 있으며, 상기 차간 거리 검출 수단(10)에서 입력되는 차간 거리(S1)와 차속 검출 수단(20)에서 입력되는 자기 차량의 속도(V1)로부터 후방 차량의 속도(V2)를 산출하고, 후방 차량의 속도(V2)가 자기 차량의 속도(V1) 보다 높은 경우(V2V1) 상기 운전석 경고부(31)를 작동시킨 다음, 상기 검출된 차간 거리(S1)가 상기 후방 차량과 자기 차량의 속도차에 따른 기준 차간 거리(S)보다 작은 작은 경우 상기 후방 차량 경고부(32)를 작동시키는 후방 차량 감지 제어부(40)로 구성된다.An embodiment of the present invention includes an inter-vehicle distance detecting means (10) for detecting an inter-vehicle distance (S1) which is a distance between a rear vehicle and a own vehicle; Vehicle speed detecting means (20) for detecting the speed of the vehicle; Proximity warning means (30) consisting of a driver's seat warning unit (31) for warning the driver of the vehicle to approach the rear vehicle, and a rear vehicle warning unit (32) for warning the driver of the rear vehicle in proximity to the front vehicle. )and; The data about the reference distance S, which is the driving stability distance according to the speed difference between the own vehicle and the rear vehicle, is stored in the memory, and the distance S1 and the vehicle speed detecting means input from the distance detecting means 10 are different. When the speed V2 of the rear vehicle is calculated from the speed V1 of the own vehicle inputted at 20, and the speed V2 of the rear vehicle is higher than the speed V1 of the own vehicle (V2V1), the driver's seat warning unit After operating 31, the rear vehicle warning unit 32 is operated when the detected inter-vehicle distance S1 is smaller than the reference inter-vehicle distance S according to the speed difference between the rear vehicle and the own vehicle. The vehicle detection control unit 40 is configured.
여기서 상기 차간 거리 검출 수단(10)은 적외선 센서 등 공지의 거리 검출 센서로 구성되고, 차속 검출 수단(20)은 자동차의 바퀴 회전수를 검출하여 주행속도를 산출하는 공기의 차속센서로 구성된다.Here, the inter-vehicle distance detecting means 10 is constituted by a known distance detecting sensor such as an infrared sensor, and the vehicle speed detecting means 20 is constituted by a vehicle speed sensor of air that detects the number of wheel revolutions of an automobile and calculates a traveling speed.
또한, 상기 운전석 경고부(31)는 도 3과 도 4a와 같이 후방 차량의 속도를 나타내어 자기 차량의 운전자로 하여금 자기 차량의 속도(V1)가 후방 차량의 속도(V2)보다 느린 것을 알려서 주의하도록 하며, 후방 차량 경고부(32)는 도 3과 도 4b가 같이 램프를 점멸하거나 또는 SPEED DOWN등의 문구를 표시하고 램프를 점멸하여 후방 차량의 운전자에게 속도를 줄일 것을 경고하게 된다.In addition, the driver's seat warning unit 31 indicates the speed of the rear vehicle as shown in FIGS. 3 and 4A so that the driver of his vehicle may be aware of the fact that the speed V1 of the vehicle is slower than the speed V2 of the rear vehicle. In addition, the rear vehicle warning unit 32 blinks the lamp as shown in FIG. 3 and FIG. 4B, or displays a phrase such as SPEED DOWN and flashes the lamp to warn the driver of the rear vehicle to reduce the speed.
그리고 후방 차량 감지 제어부(40)의 메모리에는 도 5와 같이, 자기 차량과 후방 차량의 속도차에 따른 주행 안정 거리인 기준 차간 거리(S)에 대한 데이터가 저장되어 있으며, 상기 기준 차간 거리(S)는 자기 차량과 후방 차량의 속도차가 클수록, 즉 후방 차량의 속도가 자기 차량의 속도보다 빠를 수록 길어진다.In addition, as shown in FIG. 5, the memory of the rear vehicle detecting controller 40 stores data about a reference distance S, which is a driving stability distance according to the speed difference between the vehicle and the rear vehicle, and the reference distance S ) Increases as the speed difference between the vehicle and the rear vehicle is large, that is, the speed of the rear vehicle is faster than that of the vehicle.
상기 후방 차량 감지 제어부(40)는 상기 차간 거리 검출 수단(10)에서 입력되는 차간 거리(S1)와 차속 검출 수단(20)에서 입력되는 자기 차량의 속도(V1)로부터 후방 차량의 속도(V2)를 산출한다. 그리고 후방 차량의 속도(V2)가 자기 차량의 속도(V1)보다 높은지를 판단하여 후방 차량의 속도(V2)가 자기 차량의 속도(V1)보다 높은 경우(V2V1). 먼저 상기 운전석 경고부(31)를 작동시킨다. 그러면 상기 운전석 경고부(31)는 후방 차량의 속도(V2)를 자기 차량의 운전자에게 알려주므로 운전자는 후방 차량에게 주의를 기울어지게 된다.The rear vehicle detecting control unit 40 may determine the speed V2 of the rear vehicle from the distance S1 input by the inter-vehicle distance detecting means 10 and the speed V1 of the own vehicle input by the vehicle speed detecting means 20. To calculate. In addition, when the speed V2 of the rear vehicle is determined to be higher than the speed V1 of the vehicle, the speed V2 of the rear vehicle is higher than the speed V1 of the vehicle (V2V1). First, the driver's seat warning unit 31 is operated. Then, the driver's seat warning unit 31 informs the driver of the vehicle of the speed V2 of the rear vehicle, the driver pays attention to the rear vehicle.
또한, 상기 후방 차량 감지 제어부(40)는 상기와같은 후방 차량의 속도(V2)가 자기 차량의 속도(V1)보다 높은 경우(V2V1), 상기 후방 차량과 자기 차량의 속도차를 구한 다음 상기 속도차에 따라 메모리에 저장된 기준 차간 거리(S)를 선택하고 상기 검출된 차간 거리(S1)가 상기 선택된 기준 차간 거리(S)보다 작은지를 판단한다. 즉, 후방 차량이 상기 기준 차간 거리(S) 이내로 자기 차량 후방에 접근했는지를 판단하며, 상기 판단결과 상기 차간 거리(S1)가 상기 선택된 기준 차간 거리(S) 보다 작은 경우, 상기 후방 차량 감지 제어부(40)는 상기 후방 차량 경고부(32)를 작동시킨다. 그러면 후방 차량 경고부(32)는 램플르 점멸시키거나 또는 SPEED DOWN의 문구와 함께 램프를 점멸시켜서 후방 차량의 운전자에게 자기 차량에 너무 가까이 근접하여 위험함을 경고하고 속도를 줄일 것을 요구하게 된다.In addition, the rear vehicle detection control unit 40 obtains a speed difference between the rear vehicle and the vehicle when the speed V2 of the rear vehicle is higher than the speed V1 of the vehicle (V2V1), and then calculates the speed difference. A reference distance S stored in the memory is selected according to the difference, and it is determined whether the detected distance D is less than the selected reference distance D. That is, it is determined whether the rear vehicle approaches the rear of the vehicle within the reference inter-vehicle distance S. When the inter-vehicle distance S1 is smaller than the selected reference inter-vehicle distance S, the rear vehicle detection controller 40 activates the rear vehicle warning part 32. The rear vehicle warning unit 32 then flashes the lamp or flashes the lamp with the words SPEED DOWN to warn the driver of the rear vehicle to be too close to his vehicle and to alert him to reduce speed.
그러므로 운전자는 후방 차량에 대한 시야가 확보되지 않은 상태에서 근접 경고수단을 통해서 후방 차량에 대한 정보, 후방 차량의 유무, 후방 차량의 속도 및 근접 정도 등을 얻을 수 있어 운전자가 이를 고려하여 운전하게 되므로 보다 안전한 주행을 할 수 있다.Therefore, the driver can obtain information about the rear vehicle, the presence or absence of the rear vehicle, the speed and proximity of the rear vehicle through the proximity warning means without the visibility of the rear vehicle, and the driver will drive in consideration of this. You can drive more safely.
본 발명 후방 차량 근접 감지 장치는 주행중 뒤따라 오는 후방 차량이 자기 차량에 근접한 정도를 자기 차량의 운전자에게 알리고 후방 차량의 운전자에게도 근접에 대한 경고를 하는 것으로, 후방 차량에 대한 운전자의 시야가 확보되지 않은 상태에서도 자기 차량에 근접한 차량의 유무, 속도 등의 근접의 위험성을 파악할 수 있어 안전주행을 할 수 있도록 하는 유용한 것이다.The rear vehicle proximity detecting device of the present invention informs the driver of the vehicle of the vehicle behind him while driving, and warns the driver of the vehicle of the rear vehicle that the vehicle behind the vehicle is not secured. It is useful to make it possible to drive safely because it can grasp the dangers of proximity, speed, etc. of a vehicle close to its own vehicle even in a state.
