도 1은 본 고안의 실시예에 따른 차량용 안전 거리 유지 장치의 블록 구성도이다.1 is a block diagram of a vehicle safety distance maintaining apparatus according to an embodiment of the present invention.
상기 차속 감지수단은 앞 뒤 4바퀴에 각각 설치되어 바퀴의 회전 속도를 톤 휠(tone wheel)과 센서에서의 자력선 변화로 감지하여 차량의 주행 속도를 산출하는 차속 센서(11)로 구성된다.The vehicle speed detecting means is installed in each of the front and rear four wheels is configured as a vehicle speed sensor 11 for detecting the rotational speed of the wheel by the change of the magnetic lines of force in the tone wheel and the sensor to calculate the running speed of the vehicle.
상기 이격 거리 감지수단은 차량의 전면부에 설치되어 적외선의 빔을 선행 차량에 조사하고 선행 차량으로부터의 반사를 검지하여 이격 거리를 감지하는 적외선 센서(12)로 구성된다.The separation distance detecting means includes an infrared sensor 12 installed at the front of the vehicle to irradiate a beam of infrared rays to the preceding vehicle and detect the reflection from the preceding vehicle to detect the separation distance.
상기 안전 거리 신호수단은 와이퍼 구동부(1)에 의한 와이퍼의 작동여부와 상기 차속 센서(11)에 의하여 감지된 당해 차량의 주행 속도를 기초, 데이터 테이블에 기 세팅된 산술식에 의거하여 선행 차량과의 안전 거리를 산출한 후 상기 적외선 센서(12)에 의하여 감지된 선행 차량과의 이격 거리와 비교하여 비교 결과에 따라 차량 제동 신호를 출력하는 전자 제어 유니트(21)로 구성된다.The safety distance signal means is based on the operation of the wiper by the wiper driving unit 1 and the preceding vehicle on the basis of an arithmetic expression previously set in the data table based on the traveling speed of the vehicle detected by the vehicle speed sensor 11. The electronic control unit 21 is configured to output a vehicle braking signal according to a comparison result after calculating the safety distance of the vehicle and comparing it with the separation distance from the preceding vehicle detected by the infrared sensor 12.
상기 안전 거리 유지수단은 상기 전자 제어 유니트(21)가 출력하는 차량 제동 신호에 따라 브레이크를 구동하여 차량을 제동하는 브레이크 구동부(31)로 구성된다.The safety distance maintaining means is composed of a brake drive unit 31 for braking the vehicle by driving the brake according to the vehicle braking signal output from the electronic control unit 21.
이하, 본 고안인 차량용 안전 거리 유지 장치의 작용을 일 실시예에 기초하여 설명한다.Hereinafter, the operation of the safety distance maintenance device for a vehicle according to the present invention will be described based on one embodiment.
앞 뒤 4바퀴에 각각 설치된 차속 센서(11)는 바퀴의 회전 속도를 톤휠(tone wheel)과 센서에서의 자력선 변화로 감지하여 차량의 주행 속도를 산출하여 전자 제어 유니트(21)에 입력한다.The vehicle speed sensor 11 installed at each of the front and rear four wheels detects the rotational speed of the wheel as a change of the magnetic lines of force in the tone wheel and the sensor, calculates the traveling speed of the vehicle, and inputs it to the electronic control unit 21.
또, 차량의 전면부에 설치된 적외선 센서(12)는 적외선의 빔을 전방 선행 차량에 조사하고 선행 차량으로부터의 반사를 검지하여 이격 거리를 감지하여 전자 제어 유니트(21)에 입력한다.In addition, the infrared sensor 12 installed in the front part of the vehicle irradiates an infrared beam to the front preceding vehicle, detects the reflection from the preceding vehicle, detects the separation distance, and inputs it to the electronic control unit 21.
상기 전자 제어 유니트(21)는 와이퍼 구동부(1)를 체크하여 와이퍼가 작동상태이면 상기 차속 센서(11)에 의하여 감지된 당해 차량의 주행 속도를 데이터 데이블에 기 세팅된 산출식중 우·설천시의 안전 거리 산출식에 대입하여 차량의 안전 거리를 산출한다.The electronic control unit 21 checks the wiper driving unit 1, and when the wiper is in an operating state, the driving speed of the vehicle detected by the vehicle speed sensor 11 is set in the data table. The safety distance of the vehicle is calculated by substituting the safety distance calculation formula of.
반면, 와이어 구동부(1)를 체크하여 와이퍼가 작동되지 않는 상태이면 상기 차속 센서(11)에 의하여 감지된 당해 차량의 주행 속도를 데이터 테이블에 기 세팅된 산술식중 맑은 날의 안전 거리 산출식에 대입하여 차량의 안전 거리를 산출한다.On the other hand, if the wiper is not operated by checking the wire driving unit 1, the driving speed of the vehicle detected by the vehicle speed sensor 11 is calculated according to the safety distance calculation formula on a clear day among the arithmetic formulas set in the data table. Substitute the safety distance of the vehicle.
다음으로, 산출된 안전 거리와 상기 적외선 센서(12)에 의하여 감지된 선행 차량과의 이격 거리를 비교하여 산출된 안전 거리가 선행 차량과의 이격 거리보다 크면 차량 제동 신호를 출력한다.Next, the vehicle braking signal is output when the calculated safety distance is greater than the separation distance from the preceding vehicle by comparing the calculated safety distance with the separation distance between the preceding vehicle detected by the infrared sensor 12.
이에, 브레이크 구동부(31)가 상기 전자 제어 유니트(21)가 출력한 차량 제동 신호에 따라 브레이크를 구동하여 차량을 제동한다.Accordingly, the brake driving unit 31 drives the brake according to the vehicle braking signal output by the electronic control unit 21 to brake the vehicle.
그러므로, 차량의 주행 속도가 저하되므로 선행 차량과 당해 차량의 이격 거리가 증대되어 안전 거리가 유지된다.Therefore, since the running speed of the vehicle is lowered, the separation distance between the preceding vehicle and the vehicle is increased and the safety distance is maintained.
상술한 바와 같이 본 고안의 차량용 안전 거리 유지 장치는, 차량의 주행 환경 즉, 우·설천시와 맑은 날을 구별하여 선행 차량과의 안전거리가 가변되어 자동으로 유지되게 함으로써, 선행 차량의 급정거시 발생될 수 있는 추돌 사고가 방지되는 효과가 있다.As described above, the safety distance maintenance device for a vehicle of the present invention distinguishes a driving environment of a vehicle, that is, rainy weather and a sunny day, so that the safety distance with the preceding vehicle is changed and maintained automatically, so that the sudden stopping of the preceding vehicle is performed. There is an effect that prevents a crash that can occur.
