첨부한 제1도는 본 발명에 따른 접촉사고 방지장치의 회로도이다.1 is a circuit diagram of a contact accident prevention apparatus according to the present invention.
차량의 시동여부를 감지하기 위한 시동 감지센서(S2)가 구비되고, 소정의 감지영역내에 다른 차량이나 장애물이 있는지를 감지하기 위하여 차량의 사이드 미러(14)에 물체 감지센서(S1)가 설치되며, 차량의 선회방향을 검출하기 위한 조향 스위치(SW2)와 본 발명의 장치를 수동으로 온/오프하기 위한 메인 스위치(SW1)가 갖추어져 있다.A start detection sensor S2 is provided to detect whether the vehicle is started, and an object detection sensor S1 is installed in the side mirror 14 of the vehicle to detect whether there is another vehicle or an obstacle in a predetermined detection area. And a steering switch SW2 for detecting the turning direction of the vehicle and a main switch SW1 for manually turning on / off the apparatus of the present invention.
또한, 상기 시동 감지센서(S2), 물체 감지센서(S1), 조향 스위치(SW2), 메인 스위치(SW1)로부터 출력되는 신호가 전자제어 유니트(10)로 입력되면, 전자제어 유니트(10)내의 동작 프로그램에 따라 제동을 위한 모터(M)와, 주위를 환기시키기 위한 경고등(L1)이 순차적으로 작동된다.In addition, when signals output from the start detection sensor S2, the object detection sensor S1, the steering switch SW2, and the main switch SW1 are input to the electronic control unit 10, the electronic control unit 10 According to the operation program, the motor M for braking and the warning light L1 for ventilating the surroundings are sequentially operated.
이를 좀더 상세히 설명하면, 상기 메인 스위치(SW1)가 온되고, 시동 감지센서(S2)를 통하여 차량의 시동이 걸렸음을 감지한 후, 상기 조향 스위치(SW2)를 이용하여 차량의 왼쪽인가 아니면 오른쪽인가를 검출하고, 이와 동시에 물체 감지센서(S1)로부터 소정의 감지 영역내에 다른 차량이나 장애물이 감지될 경우, 제2릴레이(RY2)를 여자시켜 경고등(L1)을 점등시키고, 이와 함께 제1릴레이(RY1)를 여자시켜 제동용 모터(M)를 구동시키면, 이 모터(M)의 축에 있는 웜 기어(20)와 이것과 연접된 웜 휠(16)이 치합 전동되고, 이 웜 휠(16)의 회전에 의해 체인(19)이 돌아가면서 브레이크 페달(17)을 당겨져 차량이 제동될 수 있게 되는 것이다.In more detail, the main switch SW1 is turned on, and after detecting that the vehicle is started through the start detection sensor S2, the left side or the right side of the vehicle is controlled using the steering switch SW2. And at the same time, when another vehicle or obstacle is detected within the predetermined detection area by the object detection sensor S1, the second relay RY2 is excited to light the warning lamp L1, and together with the first relay ( When the RY1 is excited to drive the braking motor M, the worm gear 20 on the shaft of the motor M and the worm wheel 16 connected thereto are meshed with each other and the worm wheel 16 is engaged. As the chain 19 rotates by the rotation of the brake pedal 17, the vehicle can be braked.
즉, 운전자에 의한 인위적인 페달조작이 없이도 차량이 타 차량 또는 물체와 접촉할 가능성이 있으면, 브레이크 페달이 당겨지면서 차량이 제동됨에 따라 접촉 사고를 사전에 막을 수 있는 것이다.That is, if there is a possibility that the vehicle may come into contact with another vehicle or an object without an artificial pedal operation by the driver, the braking pedal may be pulled and the vehicle may be braked to prevent contact accidents in advance.
첨부한 제2도는 조향 스위치(SW2)의 구성을 보여주고 있다.FIG. 2 shows the configuration of the steering switch SW2.
차량 스티어링휠의 축에는 조향 휠(13)이 일체 설치되고, 운전자의 휠 조작에 따라 조향 휠(13)이 회전되면서 단자 A 또는 단자 B가 조향 스위치(SW2)와 선택적으로 접점을 형성하고, 이때의 신호가 전자제어 유니트(10)로 입력된다.The steering wheel 13 is integrally installed on the shaft of the vehicle steering wheel, and the steering wheel 13 is rotated according to the driver's wheel operation, so that the terminal A or the terminal B forms a contact with the steering switch SW2 selectively. Is input to the electronic control unit (10).
첨부한 제3a도와 3b는 물체 감지센서(S1)의 구성을 보여주고 있다.3a and 3b show the configuration of the object detecting sensor S1.
상기 물체 감지센서(S1)는 차량의 사이드 미러 앞부분에 설치되어 소정의 감지영역 예를 들면, 차량의 길이에 따라 약 15cm 정도의 폭에 해당하는 영역을 커버하게 되며, 양쪽의 사이드 미러에 각각 설치되어 차량의 우회전 또는 좌회전에 따라 해당되는 쪽의 센서가 작동되어 그 감지신호를 전자제어 유니트(10)로 보낼 수 있게 된다.The object detection sensor S1 is installed at the front of the side mirror of the vehicle to cover a predetermined detection area, for example, an area corresponding to a width of about 15 cm depending on the length of the vehicle, and is installed at both side mirrors. As the right or left turn of the vehicle is activated the sensor of the corresponding side is able to send the detection signal to the electronic control unit (10).
여기서, 상기 15cm 정도의 영역은 실험에 의한 적정값이지만 차량의 사양에 따라 변경가능한 수치이다.Here, the area of about 15cm is an appropriate value by experiment, but is a numerical value that can be changed according to the specification of the vehicle.
첨부한 제4도는 제동수단의 구성을 보여주고 있다.The attached figure 4 shows the configuration of the braking means.
전자제어 유니트(10)의 제어에 따라 제동용 모터(M)가 구동되고, 이 모터(M)의 축에 있는 웜 기어(20)와 여기에 치합되어 있는 웜 휠(16)이 맞물려 회전되면 웜 휠(16)에 있는 체인(19)이 회전되며, 이 체인(19)의 회전에 따라 브레이크 페달(17)이 당겨지게 되므로서, 운전자가 브레이크 페달(17)을 밟은 것과 동일한 효과로 차량이 제동될 수 있는 것이다.When the braking motor M is driven under the control of the electronic control unit 10, and the worm gear 20 on the shaft of the motor M is engaged with the worm wheel 16 engaged therewith, the worm is rotated. The chain 19 on the wheel 16 is rotated and the brake pedal 17 is pulled according to the rotation of the chain 19, so that the vehicle is braked with the same effect as the driver stepped on the brake pedal 17. It can be.
여기서, 도면부호 18은 스프링으로서, 일정시간이 경과된 다음 자체 탄성 복원력을 이용하여 체인(19)과 웜 휠(16)을 반대방향으로 회전시켜 주는 역할을 하며, 이것에 의해 당겨졌던 브레이크 페달(17)이 원래의 위치로 복귀될 수 있게 된다.Here, reference numeral 18 denotes a spring, which rotates the chain 19 and the worm wheel 16 in the opposite direction by using a self-elastic restoring force after a predetermined time has elapsed. 17) can be returned to its original position.
첨부한 제5도는 본 발명에 따른 접촉사고 방지장치의 흐름도이다.5 is a flowchart of a contact accident prevention apparatus according to the present invention.
차량 시동 후, 제1스텝에서 차량이 왼쪽 또는 오른쪽으로 방향을 트는지의 여부를 판단하는 단계와, 제2스텝에서 센서의 감지영역내에서 다른 차량이나 장애물이 감지되는지를 판단하는 단계와, 상기 2가지 조건을 만족할 경우 차량을 제공 시키고 이와 동시에 경고등을 점등시키게 된다.Determining whether the vehicle turns to the left or the right in the first step after starting the vehicle, and determining whether another vehicle or an obstacle is detected in the sensing area of the sensor in the second step; If the two conditions are met, the vehicle is provided and at the same time the warning light is turned on.
이와 같이 밀집 주차지역에서 차량을 주차시키거나 주차된 차량을 빼내는 경우 인접한 차량이나 장애물과의 접촉 우려가 있게 되면, 이를 사전에 감지하여 차량을 제동시킴과 동시에 경고 등을 점등시킴으로써, 차량 접촉사고를 막을 수 있다.In the case of parking a vehicle in a dense parking area or removing a parked vehicle, if there is a risk of contact with an adjacent vehicle or obstacle, the vehicle is detected in advance by braking the vehicle and turning on a warning light, You can stop it.
이상에서와 같이 본 발명은 주차 밀집지역에서 차량을 주차시키거나 주차된 차량을 빼낼 때, 이를 경고함과 동시에 차량을 제동시켜 줄 수 있게 됨으로써, 차량 접촉사고를 막을 수 있는 효과가 있는 것이다.As described above, the present invention is capable of warning the vehicle and braking the vehicle when the vehicle is parked or pulled out of the parked dense area, thereby preventing vehicle contact accidents.
