본 발명은 자동차의 비상등 자동 점등에 관한 것으로, 특히 주행중 급격한 차량속도 감소시 자동으로 비상등을 점등시켜 후속 차에 위험을 알리도록 한 자동차의 비상등 자동 점등방법에 관한 것이다.The present invention relates to the automatic lighting of the emergency light of the vehicle, and more particularly, to a method of automatically lighting the emergency light of the vehicle to turn on the emergency light automatically when the sudden vehicle speed decreases while driving to inform the danger of the next car.
일반적으로 자동차의 비상등은 후속차에게 위험을 경고하기 위해 점등 시킨다.Normally, emergency lights on a car will light up to warn the car of danger.
이러한 비상등에 있어서 종래의 비상등 제어는 사용자가 수동으로 비상등 온/오프 스위치를 조작하여 제어하였다.In such emergency lights, conventional emergency light control is controlled by a user by manually operating an emergency light on / off switch.
즉, 사용자가 위험을 시각적으로 확인 한 후 후속차에게 이를 알리고자 할 경우에 비상등 온/오프 스위치를 눌러 비상등을 점등시켰고, 아울러 위험 요소가 제거된 경우에는 다시 한 번 비상등 온/오프 스위치를 눌러 비상 등을 소등시켰다. 첨고로, 비상 등을 점등시키는 대부분의 경우는 앞차의 급정거나 돌출물의 출현에 따른 급정거가 대부분을 차지하고 있다.In other words, when the user visually checks the danger and wants to inform the next car, the emergency light is turned on by pressing the emergency light on / off switch, and when the risk factor is removed, the emergency light on / off switch is pressed again. Turned off the emergency light. In most cases, emergency stops are turned on because of sudden stops in front of vehicles or sudden stops due to the appearance of protrusions.
그러나 이러한 종래의 비상등 제어방법은 사용자에 의한 수동 제어이므로 고속 주행중 순간적으로 위험이 발생된 경우에는 신속한 대처가 불가능한 문제점이 있었다. 따라서 본 발명은 상기와 같은 종래 기술의 제반 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 주행중 급격한 차량 속도 감소시 자동으로 비상 등을 점등시켜 후속 차에 위험을 알리도록 한 자동차의 비상등 자동 점등방법을 제공하는데 있다.However, such a conventional emergency light control method is a manual control by the user, there is a problem that can not be quickly dealt with when a danger occurs momentarily during high-speed driving. Therefore, the present invention is to solve the problems of the prior art as described above, an object of the present invention is to automatically turn on the emergency light when a sudden decrease in the vehicle speed while driving the emergency light automatic lighting method of the vehicle to notify the danger to the next car To provide.
이러한 본 발명의 목적을 달성하기 위한 방법은 현재의 차속을 미분하여 차속 감속 여부를 판단하고 검출한 차속과 급격한 감속 판단을 위한 제1기준 속도와를 비교하는 제1과정과, 검출한 차속이 제1기준 속도일 경우 제1기준 속도에서부터 제2기준 속도까지의 감속을 적분하는 제2과정과, 상기 적분치와 비상등 점등여부를 판단하기 위해 설정된 기준 적분치와를 비교하는 제3과정과, 상기 비교결과치와 수동 조작의 여부와를 논리하여 비상 등의 점등 유무를 판별하고 비상등 점등일 경우 자동으로 비상등이 점등되도록 제어하는 제4과정으로 이루어진다.The method for achieving the object of the present invention is to determine whether the vehicle speed deceleration by differentiating the current vehicle speed, the first process of comparing the detected vehicle speed and the first reference speed for the sudden deceleration determination, and the detected vehicle speed is A second process of integrating the deceleration from the first reference speed to the second reference speed in the case of the first reference speed, and a third process of comparing the integral value with the reference integral value set to determine whether the emergency light is turned on; A fourth process is performed by determining whether the emergency light is turned on by logic comparing the result of the comparison with the manual operation and controlling the emergency light to be automatically turned on when the emergency light is turned on.
이하, 본 발명을 첨부한 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings of the present invention.
제1도는 본 발명이 적용되는 비상등 제어장치 구성도로서, 도시된 바와 같이 자동차의 속도를 연속적으로 검출하는 속도 검출부(1)와, 상기 속도 검출부(1)에서 검출되는 가속도에 따라 비상등의 자동 점등 유무를 판단하고 자동 점등을 위한 제어신호를 발생시키는 마이콤(2)과. 상기 마이콤(2)에서 출력되는 제어신호에 의해 비상등을 점등시키는 비상등 제어부(3)로 구성되어 있다.FIG. 1 is a block diagram of an emergency light control apparatus to which the present invention is applied. As shown in FIG. 1, the speed detector 1 continuously detects the speed of a vehicle, and the emergency light is automatically turned on according to the acceleration detected by the speed detector 1. Microcomputer (2) to determine the presence and generate a control signal for automatic lighting. The emergency light control part 3 which lights an emergency light by the control signal output from the said microcomputer 2 is comprised.
이와 같이 구성된 본 발명이 적용되는 자동차의 비상등 점등장치를 참조하여 본 발명 비상등 자동 점등방법을 첨부한 도면 제2도 및 제3도에 의거 설명하면 다음과 같다.Referring to the drawings 2 and 3 attached to the emergency light automatic lighting method of the present invention with reference to the emergency light lighting device of the vehicle to which the present invention configured as described above is as follows.
먼저, 속도 검출부(1)는 현재 주행중인 자동차의 속도(V)를 연속 검출하여 마이콤(2)에 입력시키게 된다.First, the speed detector 1 continuously detects the speed V of a vehicle currently being driven and inputs it to the microcomputer 2.
마이콤(2)은 입력되는 현재의 속도(V)를 미분(즉, 특정시간 t마다의 속도의 변화량을 계산)하고 그결과치(V')를 검색하여 차 속의 변화 유무를 판단한다.The microcomputer 2 differentiates the current speed V input (that is, calculates the amount of change of the speed at each specific time t) and searches the result value V 'to determine whether the vehicle speed is changed.
즉, 미분치(V)가 0이하이고 현재의 차속(V)이 제3도에 도시한 제1기준 속도(V2)와 동일하게 되면 차 속의 감소로 판단하고 급격 제동의 검출을 위해 상기 제1기준 속도(V2)에서부터 제3도의 그래프와 같이 기설정된 제2기준 속도(V1)까지의 감속량을 적분하여 그 결과치(S)를 산출한다.That is, when the derivative value V is equal to or less than zero and the current vehicle speed V becomes equal to the first reference speed V2 shown in FIG. 3, it is determined that the vehicle speed is decreased and the first vehicle is detected for sudden braking. The resultant value S is calculated by integrating the deceleration amount from the reference speed V2 to the preset second reference speed V1 as shown in the graph of FIG.
이후 그 적분치(S)와 급격한 차속 감소를 판단하기 위해 기준으로 설정된 기준 적분치(Sf)와를 비교하고 그 결과치와 사용자에 의한 수동 조작 여부치와를 논리하여 비상 등의 점등 유무를 판단한다.Thereafter, the integral value S is compared with the reference integral value S f set as a reference to determine a sudden decrease in the vehicle speed, and the result value and the manual operation by the user are logically determined to determine whether the emergency light is turned on. .
즉, 감속시 산출한 적분치(S)가 기준 적분치(Sf) 보다 작거나 사용자 비상등 온/오프 스위치를 온시켰을 경우에는 비상 등을 점등시키는 것으로 판단을 하고 비상등을 자동 점등 시킨다.That is, when the integral value S calculated during deceleration is smaller than the reference integral value S f or the user emergency light on / off switch is turned on, it is determined that the emergency light is turned on and the emergency light is automatically turned on.
아울러 감속시 산출한 적분치(S)가 기준 적분치(Sf) 보다 크거나 사용자가 비상등 온/오프 스위치를 오프시켰을 경우에는 비상 등을 오프시키는 것으로 판단을 하고 비상등을 오프시키게 되는 것이다.In addition, when the integral value S calculated at the time of deceleration is larger than the reference integral value S f or the user turns off the emergency light on / off switch, the emergency light is judged to be turned off and the emergency light is turned off.
이후, 상기와 같은 과정이 되풀이 되면서 비상등의 온/오프 제어가 계속 수행된다.Thereafter, the above process is repeated, and the on / off control of the emergency light is continuously performed.
이상에서와 같이 본 발명은 급격한 차량 감속시 자동으로 비상등을 점등시키므로써 후속 차량에게 위험 경고를 신속히 할 수 있으므로 사고를 미연에 방지할 수 있는 효과가 있다.As described above, the present invention has an effect of preventing an accident in advance because a danger warning can be promptly issued to a subsequent vehicle by automatically turning on an emergency light when the vehicle decelerates suddenly.
