[실시예]EXAMPLE
이하, 본 발명의 바람직한 일 실시예를 첨부한 도면에 의하여 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in more detail.
제1도는 본 발명에 따른 비상등 작동장치를 개략적으로 도시한 도면이고, 제2도는 본 발명에 따른 비상등 작동장치의 동작 순서도를 도시한 도면으로, 부호(1)은 비상등 작동장치를 지칭한다.1 is a view schematically showing an emergency light operating device according to the present invention, and FIG. 2 is a view showing an operation flowchart of the emergency light operating device according to the present invention, wherein reference numeral 1 designates an emergency light operating device.
상기한 비상등 작동장치(1)는 크게 크랭크축(2)에 설치되어 회전하는 원판 펄스 휠부재(3)와, 이 원판 펄스 휠부재(3)의 이(齒)(4)를 탈락시켜 형성된 감지포인틉부(5)를 감지하는 크랭크축 포지션 센서(6)와, 이 크랭크축 포지션 센서(6)를 통해 이(齒)수를 펄스신호로 인식하는 전자제어장치와(7)와, 이 전자제어장치(7)에 의해 급정차시 점멸 작동하는 비상등(8)으로 구성되어 이루어져 있다.The above-mentioned emergency light operating device 1 is largely installed on the crankshaft 2 to detect the disk pulse wheel member 3 which rotates and the tooth 4 of this disk pulse wheel member 3 dropping off. A crankshaft position sensor 6 for sensing the point 5, an electronic controller 7 for recognizing the number of teeth as a pulse signal through the crankshaft position sensor 6, and this electronic control The device 7 is composed of an emergency light 8 that blinks when suddenly stopped.
상기한 비상등 작동장치(1)의 원판 펄스 휠부재(3)는 크랭크축(2)에 의해 회전하게 설치되어 있으며, 외주에는 소정의 이(齒)(4)를 형성하고 있으며, 이 이(齒)의 일부를 탈락시켜 형성한 감지 포인트부(5)를 이루고 있다.The disk pulse wheel member 3 of the above-mentioned emergency light operating device 1 is installed to rotate by the crankshaft 2, and a predetermined tooth 4 is formed on the outer circumference thereof. The sensing point part 5 formed by dropping a part of the s) is formed.
상기한 원판 펄스 휠부재(3)가 회전할 때 이(齒)(4)부분이 크랭크축 포지션 센서(6)를 통과할 때 교류전압이 발생하는데 이(齒)(4)에 형성된 감지 포인트부(5)에서는 교류전압의 발생 간격이 확대된다.When the disc pulse wheel member 3 is rotated, an AC voltage is generated when the tooth 4 passes through the crankshaft position sensor 6, and the sensing point portion formed on the tooth 4 is generated. In (5), the generation interval of the AC voltage is extended.
상기한 이(齒)(4)를 감지한 크랭크축 포지션 센서(6)에 의해 발생하는 교류전압은 전자제어장치(7)에 의해 펄스신호로 바뀌어져서 크랭크축(2)의 회전 각속도를 감지하게 된다.The alternating voltage generated by the crankshaft position sensor 6 having detected the teeth 4 is converted into a pulse signal by the electronic controller 7 to detect the rotational angular velocity of the crankshaft 2. do.
상기한 바와 같이 크랭크축 포지션 센서(6)에 의해 회전하는 크랭크축(2)의 각속도 감지는 원판 펄스 휠부재(3)이 이(齒)(4)사이에 형성된 감지 포인트부(5)의 회전을 인식하여 크랭크각을 검출하게 된다.As described above, the angular velocity detection of the crankshaft 2 rotated by the crankshaft position sensor 6 causes the rotation of the sensing point portion 5 in which the disc pulse wheel member 3 is formed between the teeth 4. The crank angle is detected by detecting the crank angle.
상기한 크랭크축(2)에 설치된 원판 펄스 휠부재(3)의 감지 포인트(5)를 감지하게 되면 1회전당 소요시간의 측정이 이루어지고, 이에 다른 평균 각속도의 연산이 전자제어장치(7)에 의해 이루어질 수 있게 된다.When the sensing point 5 of the disc pulse wheel member 3 installed on the crankshaft 2 is detected, the required time per revolution is measured, and the calculation of the average angular velocity is performed by the electronic controller 7. It can be made by.
그리고 전자제어장치(7)는 전회의 회전 각속도와 비교 판단하여 기준치로 설정해 놓은 급제동시의 각속도 보다 상승하게 되면 비상등(8)을 작동시킨다.Then, the electronic control device 7 operates the emergency light 8 when it rises above the angular speed at the time of rapid braking set as the reference value by comparing with the previous rotational angular speed.
이때 전자제어장치(7)는 비상등(8)을 작동시키면서 차속 센서에 의해 입력되는 차속이 0 이면 비상등(8)을 오프(OFF)시키게 되고, 이어서 차량은 정상주행을 하게 된다.At this time, the electronic control device 7 turns off the emergency light 8 when the vehicle speed input by the vehicle speed sensor while operating the emergency light 8 is 0, and then the vehicle runs normally.
상기한 바와 같이 이루어지는 본 발명에 따른 구성의 제어방법은 엔진이 구동되어 자동차가 주행하는 단계(S10)에서 자동차 주행중 엔진의 크랭크축(2)이 1회전하는데 걸리는 시간을 측정 판독하도록 한다.(S20)The control method of the configuration according to the present invention made as described above allows the engine to be driven to measure and read the time taken for the crankshaft 2 of the engine to rotate one step while driving the vehicle (S10). )
그리고 크랭크축(2)의 1회전에 소요되는 시간을 측정한 후에 크랭크축(2)의 평균 각속도를 연산하여 판독(S30)한 전자제어장치(7)는 전회의 회전 각속도를 비교 판단(S40)하게 된다.Then, after measuring the time required for one revolution of the crankshaft 2, the electronic controller 7 which calculates and reads the average angular velocity of the crankshaft 2 (S30) compares and determines the previous rotational angular velocity (S40). Done.
상기한 전자제어장치(7)는 전회의 회전 각속도를 평균 각속도에 비교 판단하여 각속도의 감소율이 기준치로 설정된 급감속이 아니면 처음의 단계(S20)로 진행되고, 반대고 급감속이면 계속 진행하도록 판단(S50)한다.The electronic controller 7 judges that the previous rotational angular velocity is compared with the average angular velocity, and proceeds to the first step S20 unless the reduction rate of the angular velocity is set as a reference value, and proceeds if the reverse high acceleration is decelerated (S50). )do.
따라서 각속도의 감소율이 기준치로 설정된 급제동에 의한 급감속이면 전자제어장치(7)는 판단하여 비상등(8)을 작동시킨다.(S60)Therefore, if the reduction rate of the angular velocity is a sudden deceleration by the sudden braking set as the reference value, the electronic control device 7 judges to operate the emergency light 8 (S60).
이와 같이 비상등(8) 작동 상태에서 전자제어장치(7)는 차속 센서를 통해 차속이 0 인가를 판단(S70)하여, 차속이 0 가 아닐 때 가속상태인가? 아닌가를 판단(S80)한다.Thus, in the emergency light 8 operation state, the electronic control device 7 determines whether the vehicle speed is zero through the vehicle speed sensor (S70), and is the acceleration state when the vehicle speed is not zero? It is determined whether or not (S80).
상기한 가속상태를 판단하여 다시 비상등(8)의 작동상태가 계속되도록 하거나, 또는 가속상태이면 비상등(8)의 오프(OFF)가 이루어지도록 판단한다.By determining the acceleration state, the operation state of the emergency light 8 is continued again, or when the acceleration state is determined, the emergency light 8 is turned off.
상기한 전자제어장치(7)에 의한 비상등(8) 작동후 차속이 0이면 비상등이 오프(OFF) 상태가 되도록 한다.(S90)If the vehicle speed is 0 after the operation of the emergency light 8 by the electronic controller 7, the emergency light is turned off. (S90)
이에 따라 비상등(8)의 오프(OFF)후에 엔진이 오프(OFF)상태인가 판단(S100)하고, 그러하지 않고 주행상태이면 처음으로 진행하고, 엔진이 멈추어 오프(OFF)이면 비상등(8)의 작동도 마치도록 판단(S110)하게 된다.Accordingly, after the emergency light 8 is turned off, it is determined whether the engine is in an off state (S100). Otherwise, if the engine is in a running state, the vehicle proceeds to the first time, and when the engine is stopped and turned off, the emergency light 8 is operated. It is determined to finish (S110).
상기한 바와 같이 전자제어장치(7)에 비상등(8)을 제어하게 되는 펄스신호(10)을 도시하고 있다.As described above, the pulse signal 10 for controlling the emergency light 8 in the electronic controller 7 is shown.
상기한 펄스 신호(10)는 감지 포인트부(5)를 크랭크 포지션 센서(6)가 감지할 때 펄스 간격이 확장되는 A, A'부분은 크랭크축(2)의 1회전을 나타내며, 이에 따른 시간을 연속적으로 측정할 수 있게 된다.When the pulse signal 10 detects the detection point part 5 by the crank position sensor 6, the A and A 'portions of which the pulse interval is extended represent one rotation of the crankshaft 2, and thus time Can be measured continuously.
상기한 크랭크축(2)의 1회전당 평균 속도는 w=2π/T 에 의해 구한다.The average speed per rotation of the crankshaft 2 described above is obtained by w = 2π / T.
이러한 본 발명은 고속도로 등에서 고속 주행에 따른 급정차시 운전자가 직접 조작하므로서 발생하는 사고의 위험을 해소하며, 또 크랭크축의 회전 각속도에 의한 가감을 감지하여 비상등을 자동으로 점멸 제어하기 때문에 안전운행이 도모된다.The present invention eliminates the risk of accidents caused by the driver's direct operation during sudden stops due to high-speed driving on the highway, and also detects deceleration due to the rotational angular velocity of the crankshaft and automatically controls the flashing of emergency lights to promote safe driving. do.
그리고 가존 장치를 이용하기 때문에 구조의 복잡화에 미치는 영향이 없어 경제적인 발명이다.And since it uses an existing device, there is no influence on the complexity of the structure, so it is an economic invention.
