본 발명은 전방 차량에 대한 속도조절 장치에 관한 것으로, 더욱 상세하게는 속도에 따른 전방차량과의 안전차간거리를 설정하여 거리측정센서 및 속도센서로 현재차량의 속도에 따른 차량과 차량과의 거리를 안전거리이상 확보할 수 있도록 제어할 수 있는 전방 차량에 대한 속도조절 장치에 관한 것이다.The present invention relates to a speed control device for a front vehicle, and more particularly, the distance between the vehicle and the vehicle according to the speed of the current vehicle by setting a distance between the front vehicle according to the speed and a distance sensor and the speed sensor. It relates to a speed control device for the front vehicle that can be controlled to ensure that the safe distance.
자동차는 사람 및 승객을 수송하는 주요한 수단이지만 부주의한 운전시 사람의 생명에도 치명적인 손상을 입힐 수 있어 안전상의 문제가 항상 최우선적으로 고려되고 있다.Although automobiles are a major means of transporting people and passengers, safety problems are always the first priority as careless driving can cause fatal damage to human life.
통상적으로 자동차를 운행하다보면 주위를 잠깐 다른데 기울이거나 졸음운전을 하게 되는 경우 가벼운 접촉사고에서부터 인명피해를 가져오는 대형사고를 유발하는 요인이 자동차에는 포함되어 있다.Normally, when driving a car, the car includes a factor that causes a serious accident that causes a casualty from casual contact and people's injury when it is inclined around another moment or drowsy driving.
특히 일정속도이상에서는 차량의 중량에 따른 관성력이 커져 제동거리가 길어지므로 장애물 돌출시나 전방차량의 급정거시 순간적으로 민첩하게 대응하지 못하여 접촉사고 및 대형사고를 가져오는 경우가 종종 있다.In particular, over a certain speed, the inertia force increases according to the weight of the vehicle, and thus the braking distance is long. Therefore, when an obstacle protrudes or a sudden stop of the vehicle ahead, it is often unable to respond quickly and quickly, resulting in contact accidents and large accidents.
따라서 자동차는 반드시 전방차량과는 속도에 따라 일정 차간거리를 확보해야 함에도 불구하고 종래의 자동차는 이에 대한 차량자체의 대비책이나 조정수단이 없어 운전자의 운전숙련도나 운전습관에 맡기고 있는 실정이다.Therefore, although the vehicle must secure a certain distance between vehicles according to the speed of the vehicle ahead of the vehicle, the conventional vehicle does not have a vehicle's own countermeasures or adjustment means to leave it to the driver's driving skills or driving habits.
즉, 이와같이 종래의 자동차는 속도에 따라 전방차량과의 차간거리를 제어할 수 있는 수단이 없어 가벼운 접촉사고 및 대형사고를 유발할 위험성이 존재하는 문제가 있었다.That is, the conventional vehicle has a problem that there is a risk of causing a light contact accident and a large accident because there is no means for controlling the distance between the vehicle and the vehicle in accordance with the speed.
본 발명은 이와같은 종래의 문제점을 감안하여 발명한 것으로, 차량의 전방 장애물까지의 거리를 측정하여 그에 따르는 제한 속도를 설정하여 그 이상의 속력을 제한함으로서 전방 장애물과의 거리가 가까워짐에 따라 그 제한 속도도 점점 낮아져서 최종적으로 차량이 정지하도록 하는 전방 차량에 대한 속도조절 장치를 제공하는데 본 발명의 목적이 있다.The present invention has been invented in view of the above-described conventional problems, by measuring the distance to the front obstacle of the vehicle and setting the speed limit according thereto to limit the speed further, the speed limit as the distance to the front obstacle gets closer. It is an object of the present invention to provide a speed regulating device for a front vehicle which is gradually lowered to finally stop the vehicle.
상기와 같은 목적을 실현하기 위한 본 발명은 전방 장애물까지의 거리를 측정할 수 있는 거리측정수단과 속도를 감지할 수 있는 속도감지수단과 가속페달의 눌려진 정도를 측정하여 운전자의 가속의지를 판단할 수 있는 가속센서와 현재속도를 거리에 따라 설정된 제한속도와 비교하여 제한 속도로 조절하는 속도조절수단 및 이를 선택할 수 있는 선택스위치를 구비한 것으로, 운전자의 운전습관이나 부주의로 전방차량과 일정거리에서 설정된 제한속도를 초과하면서 가속되면 속도조절수단에 의해 제한속도로 조절되어 차간거리가 가까워짐에 따라 차량의 속도도 떨어져 전방차량과의 안전거리를 확보할 수 있도록 유도하는 효과를 가져올 수 있다.The present invention for realizing the above object is to determine the driver's acceleration will by measuring the pressed degree of the distance measuring means and the speed sensing means for detecting the speed and the accelerator pedal to measure the distance to the front obstacle. It is equipped with an acceleration sensor and a speed control means for adjusting the current speed to the speed limit compared to the speed limit set according to the distance, and a selector switch for selecting the speed, at a certain distance from the vehicle ahead of the driver's driving habit or carelessness. Accelerating while exceeding the set speed limit may be controlled to the speed limit by the speed control means to reduce the speed of the vehicle as the distance between the cars closer to bring the effect of inducing a safe distance to the vehicle ahead.
이하 상기한 바와 같은 본 발명에 의한 전방 차량에 대한 속도조절 장치를 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.Hereinafter, the speed control device for the front vehicle according to the present invention as described above will be described in more detail based on the accompanying drawings.
본 발명은 전방 장애물까지의 거리를 측정하도록 된 거리측정수단(10)과, 속도를 감지할 수 있는 속도감지수단(12)과, 가속페달의 눌려진 정도를 측정하여 운전자의 가속의지를 판단할 수 있는 가속센서(14)가 ECU(20)의 입력측에 연결되고, 현재속도를 거리에 따라 설정된 제한속도에 비교하여 제한속도로 조절하는 속도조절수단(16)이 ECU(20)의 출력측에 연결되되, 상기 속도조절수단(16)의 작동여부는 ECU(20)의 입력측에 연결된 선택스위치(18)로 선택되도록 된 전방 차량에 대한 속도조절 장치이다.The present invention can determine the driver's acceleration will by measuring the distance measuring means 10 to measure the distance to the front obstacle, the speed detecting means 12 for detecting the speed, and the pressed degree of the accelerator pedal. Accelerometer 14 is connected to the input side of the ECU 20, speed control means 16 for adjusting the current speed to the speed limit compared to the speed limit set according to the distance is connected to the output side of the ECU 20 The operation of the speed regulating means 16 is a speed regulating device for the front vehicle which is to be selected by the selection switch 18 connected to the input side of the ECU 20.
예시도면 제1도는 본 발명에 따른 전방 차량에 대한 속도조절 장치의 구성을 보인 구성도이며, 예시도면 제2도는 본 발명에 따른 전방 차량에 대한 속도조절방법을 보인 흐름도이다.Exemplary Drawing 1 is a block diagram showing a configuration of a speed control device for a front vehicle according to the present invention, Figure 2 is a flow chart showing a speed control method for a front vehicle according to the present invention.
상기 제한속도는 차량의 속도에 따른 관성력을 고려하여 제동거리를 확보할 수 있도록 차간안전거리에 따라 속도를 설정하여 ECU(20)에 입력된다.The speed limit is input to the ECU 20 by setting the speed according to the safety distance between the vehicles so as to secure a braking distance in consideration of the inertia force according to the speed of the vehicle.
또한, 상기 ECU(20)에서는 상기 거리측정수단(10) 및 속도감지수단(12)에 의해 감지된 거리 및 속도를 거리에 따른 제한속도와 비교한다.In addition, the ECU 20 compares the distance and the speed detected by the distance measuring means 10 and the speed detecting means 12 with the speed limit according to the distance.
이와같이 비교한 현재속도가 전방차량과의 이격거리에 비해 제한속도를 초과하면 ECU(20)에서 브레이크를 작동시켜 제한속도를 초과하지 않도록 하고, 운전자가 가속페달을 밟는 경우 이를 가속센서(14)에 의해 감지하여 가속페달의 작동을 일시적으로 정지시킨다.When the current speed compared in this way exceeds the speed limit compared to the distance from the front vehicle, the ECU 20 operates the brake so as not to exceed the speed limit, and when the driver steps on the accelerator pedal, it is applied to the acceleration sensor 14. It senses it and temporarily stops the operation of the accelerator pedal.
한편, 이와같은 속도조절 장치의 작동여부를 운전자가 선택할 수 있는 선택스위치(18)가 제어루프의 일단에 설치되어 있다.On the other hand, a selector switch 18, which allows the driver to select whether the speed regulation device is operated, is provided at one end of the control loop.
예시도면 제3도는 본 발명에 따른 거리측정수단(10)의 설치상태를 보인 개략도로서, 상기 거리측정수단(10)은 레이저 광원(22)과 반사경(24)을 갖는 센서로 구성되어 프런트 범퍼(26)의 양단에 설치된다.3 is a schematic view showing the installation state of the distance measuring means 10 according to the present invention, wherein the distance measuring means 10 is composed of a sensor having a laser light source 22 and a reflector 24 and a front bumper ( 26) are installed at both ends.
즉, 광에서 주사되는 레이저를 통해 전방의 장애물을 감지한 후 반사되는 레이저를 반사경(24)을 통해 감지하여 센서의 전압의 변화에 따라 거리를 감지하도록 된 것이다.In other words, after detecting the obstacle in front of the laser scanning from the light through the reflector 24 to detect the reflected laser to detect the distance in accordance with the change in the voltage of the sensor.
한편, 경보수단(28)을 설치하여 설정 제한속도 이상으로 현재속도를 증가시키려고 하는 경우 경보장치가 작동하도록 하므로서 운전자의 주의력을 환기시키는 수단도 가능하다.On the other hand, when the alarm means 28 is installed to increase the current speed above the set speed limit, it is also possible to alert the driver's attention by operating the alarm device.
이하 본 발명에 따른 전방 차량에 대한 속도조절 장치의 실시예를 설명하면 다음과 같다.Hereinafter, an embodiment of a speed control device for a front vehicle according to the present invention will be described.
예시도면 제4도는 본 발명에 따른 거리-제한속도의 관계를 나타낸 그래프로서, 본 발명에 따르면 운전자가 속도조절 장치의 선택스위치(18)를 선택해야만 작동하게 됨은 주지된 바와 같으며, 운전자가 자신도 모르게 주행중 전방차량과 일정거리 이상 가까워지려고 가속페달을 밟으면 ECU(20)에서 현재속도와 설정된 제한속도를 비교판단하여 가속페달의 작동을 일시적으로 정지시키면서 제한속도를 초과하지 않도록 제어한다.Exemplary Drawing 4 is a graph showing the relationship between the distance-limiting speed according to the present invention, and it is well known that the driver operates only by selecting the selection switch 18 of the speed regulating device according to the present invention. If you step on the accelerator pedal to get closer to the vehicle ahead of a certain distance while driving, the ECU 20 compares the current speed and the set speed limit, and stops the operation of the accelerator pedal temporarily so as not to exceed the speed limit.
한편, 고속도로 상에서 추월하고자 하는 경우에는 당연히 차의 진행방향이 전방차량과 사선방향으로 비틀리게 되므로 거리감지수단이 전방의 장애물을 인식하지 못하게 되어 운전자가 요구하는 속도를 이용해 바로 추월할 수 있으며, 선택스위치(18)를 조작할 필요는 없다.On the other hand, if you want to pass on the highway, of course, the direction of the car is twisted in the oblique direction with the vehicle ahead, so that the distance sensing means does not recognize the obstacle in front of you and can pass immediately using the speed required by the driver. It is not necessary to operate the switch 18.
이상에서 상세히 설명한 바와 같이, 본 발명에 의한 전방 차량에 대한 속도조절장치에 따르면 전방차량과의 적절한 차간거리를 유지할 수 있도록 제어하므로서 운전자의 운전습관이나 부주의로 인한 접촉사고나 대형사고를 미연에 방지할 수 있는 효과를 얻을 수 있다.As described above in detail, according to the speed control device for the front vehicle according to the present invention by controlling to maintain a proper distance between the vehicle and the front of the driver to prevent accidents or large accidents due to driving habits or carelessness The effect can be obtained.
