그런데, 상기와 같은 비교예는 문제점이 발생하는 바, 먼저 가속도 센서를 이용한 비상등 자동 점등회로는 차량에 가속도 센서(1)를 추가적으로 부착해야 하며, 이와 관련된 회로도 추가적으로 제작해야 한다는 점에서, 추가적인 비용부담이 발생한다.However, the comparative example as described above has a problem, firstly, the emergency light auto-lighting circuit using the acceleration sensor has to additionally attach the acceleration sensor 1 to the vehicle, and additionally bears additional costs in that the related circuits must be additionally manufactured. This happens.

또한, 상기 가속도 센서(1)는 현재 자동차의 안정성, 신뢰성, 안락성, 편의성 향상을 위하여 전자식 엔진 제어시스템, ABS(Anti-lock Braking System), 지능형 현가장치(Smart Suspension System), 조향 시스템, 자동 잠금장치 등에 사용되고 있으나, 거의 모두가 기계식이기 때문에 코일 내에 장치된 이동체가 가속에 의해 움직일 시, 자장의 변화를 측정하는 서보 타입(Servo Type)이 대표적인 예이다.In addition, the acceleration sensor 1 is an electronic engine control system, an anti-lock braking system (ABS), an intelligent suspension system (Smart Suspension System), a steering system, and an automatic lock to improve the stability, reliability, comfort, and convenience of the current vehicle. Although it is used in an apparatus or the like, almost all of them are mechanical, and a servo type for measuring a change in a magnetic field when a moving body installed in a coil moves by acceleration is a typical example.

이러한, 기계식 가속도 센서(1)는 구조가 복잡하고, 크고 무거우며 규격 양산이 힘들어 신뢰성이 낮고, 가격이 높아 그 활용이 제한된다.Such a mechanical acceleration sensor 1 is complicated in structure, large and heavy, difficult to mass-produce a standard, low reliability, high price, and its use is limited.

물론, 소형인 실리콘 가속도 센서가 있기는 하지만 사용되는 분야에 따라 센서의 감지특성(Sensing Characteristics), 신뢰성(Reliability), 적용성(Applicability), 생산성(Productibility) 등의 4가지가 동시에 고려되어야 하기 때문에 차량속도를 측정하기 위해 차량에 이를 적용하기 위해서는 가속도 센서에 대한 추가적인 연구가 필요하다.Of course, although there is a small silicon acceleration sensor, depending on the field of use, the four characteristics such as sensing characteristics, reliability, applicability, and productivity must be considered at the same time. Further research on acceleration sensors is needed to apply it to vehicles to measure vehicle speed.

또한, 제동장치를 이용한 비상등의 자동 점등에 대한 기술은 현재의 차량속도가 일정속도 이상이고 브레이크의 기울기가 설정된 값을 넘었을 경우에 작동하는 방식으로 이 두상태를 통해 차량의 감속상태를 판단한다는 데에 한계를 가지고 있을 뿐더러 브레이크에 여러가지 기구를 추가적으로 설치해야 하므로 이 또한 비용적인 추가가 요구되는 문제점이 있다.In addition, the technology for automatic lighting of the emergency light using the braking device is to operate when the current vehicle speed is over a certain speed and the brake slope exceeds the set value. In addition, there is a problem in that it requires a costly addition because there are limitations in addition to the installation of various mechanisms in the brake.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로서, 기존의 자동차에 장착되는 차속센서 및 차륜센서의 속도신호를 제어장치에서 연산처리하여 차량속도와 차륜속도를 얻게되고, 급제동 시에 발생하는 슬립율을 연산처리하여 비상등을 자동으로 점등되도록 제어함으로써, 추가적인 비용이 소요되지 않으며, 기존 차량에 장착되어 있는 인증 센서들을 사용하므로 내구성 또는 신뢰성을 충분히 만족시킬 수 있는 자동차의 비상등 자동점등 제어방법를 제공하는데 그 목적이 있다.Therefore, the present invention has been made in order to solve the above problems, the speed signal of the vehicle speed sensor and the wheel sensor mounted on an existing vehicle is processed by the control device to obtain the vehicle speed and the wheel speed, when sudden braking By controlling the generated slip rate to automatically turn on the emergency light, no additional cost is incurred, and the emergency light automatic lighting control of the car can satisfy the durability or reliability by using the authentication sensors installed in the existing vehicle. The purpose is to provide a method.

이하, 상기와 같은 목적을 달성하기 위한 본 발명의 특징에 대해 설명하면 다음과 같다.Hereinafter, the features of the present invention for achieving the above object are as follows.

본 발명에 따른 자동차의 비상등 자동점등 제어방법은 설정 차량속도이상 일 경우, 차속센서에서 감지된 차량속도와, 차륜센서에서 감지된 차륜속도를 통해 제어장치에서 두입력 신호를 비교하여 연산처리된 슬립율이 설정 슬립율보다 클 경우에 비상등이 점등되도록 제어하는 것을 특징으로 한다.According to an exemplary embodiment of the present invention, an emergency lighting control method for an auto lighting system includes a slip processed by comparing two input signals at a control device through a vehicle speed detected by a vehicle speed sensor and a wheel speed detected by a wheel sensor when the vehicle speed is higher than a set vehicle speed. When the rate is greater than the set slip rate, the emergency light is characterized in that the control to turn on.

특히, 상기 설정 차량속도는 50km/h이고, 설정 슬립율은 20%인 것을 특징으로 한다.In particular, the set vehicle speed is 50km / h, characterized in that the set slip ratio is 20%.

이하, 첨부도면을 참조하여 본 발명의 구성에 대해 상세하게 설명하면 다음과 같다.Hereinafter, the configuration of the present invention with reference to the accompanying drawings in detail.

도 1은 본 발명에 따른 자동차의 비상등 자동점등 제어방법을 나타내는 순서도,1 is a flow chart showing a method for controlling emergency light automatic lighting of a vehicle according to the present invention;

도 2는 본 발명에 따른 슬립율에 대한 제동력을 나타내는 그래프이다.2 is a graph showing the braking force with respect to the slip ratio according to the present invention.

본 발명은 기존 차량에 장착된 차속센서와 차륜센서를 이용하여 차량속도 및 차륜속도를 통해 제어장치에서 연산처리된 타이어의 슬립율을 설정슬립율과 비교하여 급 감속 시, 비상등을 점등 가능하도록 하는 발명인 것이다.The present invention compares the slip rate of the tire computed by the control device with the vehicle speed and the wheel speed by using the vehicle speed sensor and the wheel sensor mounted on the existing vehicle to enable the emergency light to be turned on at the time of rapid deceleration. It is an invention.

상기 차속센서는 자기 접점방식으로서, 내구성이 강하고, 차량속도를 감지하기 위해 스피드미터 드리븐 기어의 회전수를 검출하여 차량속도를 계산한다.The vehicle speed sensor is a magnetic contact method, and has a high durability, and calculates the vehicle speed by detecting the rotation speed of the speed meter driven gear to detect the vehicle speed.

또한, 상기 차륜센서는 내부에 자석과 코일로 구성되어 있고, 소형 발전기의 원리를 이용하게 되는데, 이때 발생하는 전압 및 진폭을 이용해 타이어의 속도를 감지한다.In addition, the wheel sensor is composed of a magnet and a coil inside, and uses the principle of a small generator, at this time to detect the speed of the tire using the voltage and amplitude generated.

상기와 같이, 차속센서와 차륜센서를 사용하여 급제동 시, 자동차의 비상등을 자동으로 점등하려는 바, 먼저 차속센서를 통해 설정된 차속(50km/h)이상일 때에만 비상등이 작동하며, 저속 시에는 자동 점등장치가 작동되지 않도록 되어 있다.As described above, when emergency braking using the vehicle speed sensor and the wheel sensor, the emergency light of the car is to be automatically turned on. First, the emergency light operates only when the vehicle speed (50km / h) or more is set through the vehicle speed sensor, and the vehicle lights automatically at low speed. The device is disabled.

이때, 도 1에 도시된 바와 같이, 설정된 차량속도이상 일 경우에는 차속센서에서 감지된 차량속도와 타이어에 장착된 차륜센서에서 감지된 차륜속도를 통해 제어장치에서 두입력 데이터를 비교하여 연산처리된 슬립율이 설정 슬립율보다 클 경우, 비상등이 작동되도록 제어하게 된다.In this case, as shown in FIG. 1, when the vehicle speed is higher than the set vehicle speed, the control device compares two input data with the vehicle speed detected by the vehicle speed sensor and the wheel speed detected by the wheel sensor mounted on the tire. If the slip ratio is greater than the set slip ratio, the emergency light is controlled to operate.

상기 슬립율은 ABS(Anti-lock Braking System)의 작동을 위해 사용되는 요소로서, 타이어에 구동력 또는 제동력이 작용하면 차량속도와 타이어의 차륜속도는 일치하지 않게 되며, 노면과 타이어 사이에 미끄러짐(slip)이 발생하며, 이 슬립에 의해 차량이 가속되거나 감속되는데, 이때 차량속도와 차륜속도와의 차이를 비율로 나타낸 것이 슬립율이며, 노면상태에 따라 슬립율은 차이가 나지만, 어느 조건에서나 슬립율이 15~20%일 때 제동력이 최대가 되며, 아래와 같은 식으로 계산된다.The slip ratio is an element used for the operation of the anti-lock braking system (ABS). When the driving force or the braking force is applied to the tire, the vehicle speed and the wheel speed of the tire do not coincide, and the slip between the road surface and the tire (slip) ), The vehicle is accelerated or decelerated by this slip, and the slip rate is the ratio of the difference between the vehicle speed and the wheel speed, and the slip rate varies depending on the road surface. At this 15 ~ 20%, the braking force becomes the maximum and is calculated as follows.

슬립율(%) = (차량속도 - 차륜속도)/차량속도 ×100Slip Rate (%) = (Vehicle Speed-Wheel Speed) / Vehicle Speed × 100

일반적으로, 슬립율이 0%일 때를 차량의 정지상태, 슬립율이 100%일 때를 주행 중, 차륜이 완전히 잠긴 상태(lock)라 할 수 있다.In general, when the slip ratio is 0%, the vehicle is in a stationary state, and when the slip ratio is 100%, the wheel may be completely locked while driving.

이러한 슬립율의 원리를 이용하여 고속일 때, 급제동을 수행하면 슬립이 발생되는데, 이 슬립율을 연산처리하여 미리 설정 슬립율보다 클 경우에 비상등이 자동으로 점등되도록 되는 것이다.By using the principle of the slip rate at high speed, if a sudden braking is performed, slip is generated. When the slip rate is calculated, the emergency light is automatically turned on when the slip rate is larger than the preset slip rate.

도 2는 슬립율에 대한 제동력을 나타내는 그래프로서, 이를 통해 사전에 슬립율을 설정할 수 있게 되는데, 일반적으로 급제동이라고 할 수 있는 슬립율의 양을 본 발명에서는 도 2에 도시된 바와 같이, 20%로 설정한다.Figure 2 is a graph showing the braking force against the slip rate, it is possible to set the slip rate in advance, the amount of slip rate that can be generally referred to as a rapid braking in the present invention, as shown in Figure 2, 20% Set to.

이상에서 상술한 바와 같이, 본 발명에 따른 자동차의 비상등 자동점등 제어방법은 기존의 자동차에 장착되는 차속센서 및 차륜센서의 속도신호를 제어장치에서 연산처리하여 차량속도와 차륜속도를 얻게되고, 급제동 시에 발생하는 슬립율을 연산처리하여 비상등을 자동으로 점등되도록 제어함으로써, 추가적인 비용이 소요되지 않으며, 기존 차량에 장착되어 있는 인증 센서들을 사용하므로 내구성 또는 신뢰성을 충분히 만족시킬 수 있는 효과가 있다.As described above, in the emergency light automatic lighting control method of the vehicle according to the present invention by calculating the speed signal of the vehicle speed sensor and the wheel sensor mounted on the existing vehicle in the control device to obtain the vehicle speed and the wheel speed, and sudden braking By calculating the slip rate generated at the time of operation to control the emergency light to be automatically turned on, no additional cost is required, and since the authentication sensors installed in the existing vehicle are used, the durability or reliability can be sufficiently satisfied.
