본 고안은 차속감응식 비상등회로에 관한 것으로서, 좀 더 상세히는 자동차가 소정속도 이상의 고속주행 중에 급제동을 하게 되면 자동적으로 비상등이 점등되도록 한 차속감응식 비상등회로에 관한 것이다.The present invention relates to a vehicle speed-sensitive emergency light circuit, and more particularly, to a vehicle speed-sensitive emergency light circuit for automatically turning on the emergency light when the vehicle brakes rapidly during a high speed over a predetermined speed.

주행중인 자동차가 급제동을 하게 되면 후방차량의 운전자가 이를 인식하지 못하거나 이를 인식하더라도 미처 대처하지 못하여 추돌사고를 일으키거나 인접차량이나 지형지물에 충돌하게 되는 등 교통사고를 유발하게 된다. 그런데, 이러한 급제동을 하는 경우에 운전자가 인접차량에게 긴급한 상황을 알리는 적절한 수단이 기존의 자동차에는 제공되어 있지 않다. 종래의 비상등은 운전자의 수동조작에 의해 작동되므로 급제동을 요하는 긴급상환에서 운전자가 신속하게 비상등을 점등시키는 것을 기대하기는 곤란하다.When the driving car suddenly brakes, the driver of the rear vehicle may not recognize it, or even if it recognizes it, it may not cope with it, causing a crash or crashing into an adjacent vehicle or a feature. However, in the case of such sudden braking, there is no suitable means for the existing vehicle to inform the driver of the emergency situation to the adjacent vehicle. Since a conventional emergency light is operated by the driver's manual operation, it is difficult to expect the driver to turn on the emergency light quickly in an emergency situation requiring rapid braking.

본 고안은 전술한 바와 같은 급제동시의 문제점에 착안하여 제안된 것으로서, 자동차가 일정속도 이상으로 주행하는 중에 급제동을 하게 되면 이를 감지하여 자동으로 비상등을 점등시키는 차속감응식 비상등회로를 제공 하고자 하는 것이다.The present invention has been proposed in view of the problems of the sudden braking as described above, to provide a vehicle speed-sensitive emergency light circuit that detects this when the car suddenly brakes while driving at a certain speed and automatically turns on the emergency light. .

본 고안에 따르면, 자동차의 브레이크페달에 연동되는 가동탭을 구비한 가변저항부와, 상기 가변저항부의 가동탭에 접속되며 가동탭에서 검출되는 변동점압이 인가되어 충방전되는 콘덴서와, 자동차의 속도계로부터의 차속 신호가 입력되며 차속이 소정치를 초과하면 하이신호를 출력하는 차속판별부와, 상기 콘덴서의 출력신호와 상기 차속판별부의 출력신호가 각각 입력되는 AND게이트와, 상기 AND게이트의 출력단에 접속되며 AND게이트의 하이신호 출력시간을 카운트하여 소정시간 이상이면 하이신호를 출력하는 제동시간판별부와, 상기 제동시간판별부의 출력단에 접속되는 비상등구동부를 포함하는 것을 특징으로 하는 차속감응식 비상등회로가 제공된다.According to the present invention, a variable resistor unit having a movable tab interlocked with a brake pedal of a vehicle, a capacitor connected to the movable tab of the variable resistor unit, and having a variable point pressure detected by the movable tab applied and charged and discharged, and a speedometer of a vehicle A vehicle speed discrimination unit for outputting a high signal when a vehicle speed signal from the vehicle speed exceeds a predetermined value, an AND gate to which an output signal of the capacitor and an output signal of the vehicle speed discrimination unit are respectively input, and an output terminal of the AND gate And a braking time judging unit connected to the high signal output time of the AND gate and outputting a high signal when it is equal to or greater than a predetermined time, and an emergency light driver connected to an output terminal of the braking time judging unit. Is provided.

이하에서 도면을 참조하여 본 고안의 바람직한 실시예를 설명한다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention.

제1도는 본 고안에 따른 차속감응식 비상등회로의 구성도로서, 도시된 바와 같이, 속도계(1)와 차속판별부(2)가 순차로 접속되어 차속판별부(2)의 출력신호가 AND게이트(G2)의 하나의 입력단에 입력된다. 한편, 브레이크페달(3)의 회동작동에 연동되는 가동탭(4)을 구비한 가변저항(VR)의 일단에는 시동스위치(S1)을 통해 전원(B+)이 인가되며, 가동탭(4)의 후단에는 NOT게이트(Gl)와 결합콘덴서(C1)을 거쳐 충방전 콘덴서(C2)와 저항(Rl)이 병렬로 접속되어 접지된다. 그리고 충방전콘덴서(C2)의 출력단은 (소신호증폭 트랜지스터(TR2)를 거쳐) AND게이트(G2)의 다른 입력단에 접속된다.1 is a block diagram of a vehicle speed-sensitive emergency light circuit according to the present invention, and as shown, the speedometer 1 and the vehicle speed discrimination unit 2 are sequentially connected so that the output signal of the vehicle speed discrimination unit 2 is AND gated. It is input to one input terminal of (G2). On the other hand, a power source B + is applied to one end of the variable resistor VR having the movable tab 4 interlocked with the rotation operation of the brake pedal 3 through the start switch S1, At the rear end, the charge / discharge capacitor C2 and the resistor Rl are connected in parallel through the NOT gate Gl and the coupling capacitor C1 and grounded. The output terminal of the charge / discharge capacitor C2 is connected to the other input terminal of the AND gate G2 (via the small signal amplifier transistor TR2).

그리고, AND게이트(G2)의 출력단에는 제동시간판별부(6)와 비상등구동부(7)가 순차 접속된다. 이 비상등 구동부(7)와 병렬로 통상적인 비상등스위치(S2)와 비상등점멸제어부(10)가 구비되며, 비상동구동부(7)와 비상등 점멸제어부(10)에 의해 비상등(L)이 점등된다.The braking time discriminating section 6 and the emergency light driving section 7 are sequentially connected to the output terminal of the AND gate G2. The emergency light switch S2 and the emergency light blink control unit 10 are provided in parallel with the emergency light drive unit 7, and the emergency light L is turned on by the emergency drive unit 7 and the emergency light blink control unit 10.

이러한 구성에 따른 본 고안의 작동을 설명하면 다음과 같다.Referring to the operation of the present invention according to this configuration is as follows.

속도계(1)에서 검출된 차속신호는 차속판별부(2)로 입력되며 차속판별부(2)에서는 차량속도가 소정치, 예를들면 40km/h를 초과하면 AND게이트(G2)로 하이신호를 출력시킨다. 한편, 브레이크페달(3)을 밟으면 페달을 움직임에 따라 작동되는 브레이크페달스위치(4)에 연동되는 가동탭(5)이 가변저항(VR)을 따라 이동하게 되고, 가동탭(5)의 위치에 따라 변동되는 검출전압은 NOT게이트(Gl)에 의해 반전되고 결합콘덴서(C1)를 거치면서 변동신호 성분만이 통과되어 콘덴서(C2)에 충전된다. 여기서, NOT게이트(G2)의 후단에서 측정한 검출전압은 일반적인 제동시에는 제2a도에서와 같이 완만한 상승곡선(al)을 이루지만, 급제동시에는 제2b도에서와 같이 급격한 상승곡선(bl)을 이루게 된다. 따라서, 콘덴서(C2)의 출력단의 신호는 일반제동시에는 제3a도와 같이 상대적으로 긴 상승곡선과 이에 따른 긴 하이레벨주기(tl)를 나타내며, 급제동시에는 제3b도에서와 같이 상대적으로 짧은 상승곡선과 이에 따른 짧은 하이레벨주기(t2)를 나타낸다.The vehicle speed signal detected by the speedometer 1 is input to the vehicle speed judging section 2, and when the vehicle speed exceeds a predetermined value, for example, 40 km / h, the high signal is sent to the AND gate G2. Output On the other hand, when the brake pedal 3 is pressed, the movable tab 5 linked to the brake pedal switch 4 operated according to the movement of the pedal moves along the variable resistor VR, and the position of the movable tab 5 is moved. The detection voltage which varies accordingly is inverted by the NOT gate Gl, and only the variable signal component is passed through the coupling capacitor C1 to charge the capacitor C2. Here, the detection voltage measured at the rear end of the NOT gate G2 forms a gentle rising curve al as shown in FIG. 2a during normal braking, but a sharp rising curve bl as shown in FIG. 2b during sudden braking. ) Is achieved. Accordingly, the signal at the output terminal of the capacitor C2 shows a relatively long rising curve and a long high level period tl as shown in FIG. 3a during normal braking, and a relatively short rise as shown in FIG. 3b during sudden braking. Curve and thus a short high level period t2.

이와 같이, 브레이크페달을 밟는데 소요된 시간에 따른 콘덴서(C2)의 출력신호는 트랜지스터(TR2)에 의해 증폭된 후 전술한 차속판별부(2)의 신호와 함께 AND게이트(G2)에 입력된다. 따라서, 자동차의 속도가 소정치 이상이어서 차속판별부(2)로부터 하이신호가 입력되는 동안에는 AND게이트(G2)는 콘덴서(C2)로부터 하이신호가 입력되는 동안만큼 하이신호를 출력한다. AND게이트(G2)의 출력은 제동시간판별부(6)로 입력되며, 이 제동시간판별부(6)에서는 AND게이트(G2)의 하이신호주기를 기준펄스로 카운트하여 소정펄스수 이하이면, 즉 제동시간이 소정시간(예를들면 0. 5초 이하이면) 이하의 급제동인 경우에 하이신호를 출력하여 후단의 비상등구동부(7)를 구동시킨다.As such, the output signal of the capacitor C2 according to the time taken to press the brake pedal is amplified by the transistor TR2 and then input to the AND gate G2 together with the signal of the vehicle speed discriminating unit 2 described above. . Therefore, while the speed of the vehicle is greater than or equal to the predetermined value and the high signal is input from the vehicle speed judging section 2, the AND gate G2 outputs the high signal as much as the high signal is input from the capacitor C2. The output of the AND gate G2 is input to the braking time judging section 6, where the braking time judging section 6 counts the high signal period of the AND gate G2 as a reference pulse, i.e. When the braking time is a sudden braking for less than a predetermined time (for example, 0.5 seconds or less), a high signal is output to drive the emergency light driver 7 at the rear stage.

이 비상등구동부(7)는 통상적인 비상등스위치(S2)나 비상등점멸제어부(10)와는 별도로 이들과 병렬로 제공되며, 트랜지스터(TR)과 시정수설정부(C, R)을 구비하여, 제동시간판별부(6)의 하이신호에 따라 시정수설정부(C. R)에 의해 정해지는 소정시간(예를들면 3 내지 5초) 동안 트랜지스터(TR)를 온시켜서 비상등(L)을 점등시킨다. 바람직하게는 이 비상동(L)으로는 좌우 방향지시등(Ll. L2)을 사용하며 도시된 회로에서는 이들비상등(L)을 일정시간 점등상태로 유지하는 것으로 설명하였으나, 통상적인 비상등조작과 마찬가지로 비상등을 일정시간 점멸시켜도 좋을 것이다.The emergency light driving unit 7 is provided in parallel with the emergency light switch S2 or the emergency light flashing control unit 10 separately from each other, and includes a transistor TR and a time constant setting unit C and R to determine braking time. The emergency light L is turned on by turning on the transistor TR for a predetermined time (for example, 3 to 5 seconds) determined by the time constant setting unit C. R in accordance with the high signal of the section 6. Preferably, the emergency operation L is used as a left and right direction indicator light (Ll. L2), and the circuit shown in the figure shows that these emergency lights L are kept on for a predetermined time. May flash for a period of time.

이상에서 설명한 본 고안에 따르면, 자동차가 소정속도 이상의 고속으로 주행하는 중에 급제동을 걸게 되면, 자동적으로 비상등이 일정시간 점등되므로 후방차량의 운전자에게 긴급상황임을 효과적으로 알릴 수 있어서, 교통사고의 예방에 기여할 수 있다.According to the present invention described above, if the car brakes suddenly while driving at a high speed of a predetermined speed or more, the emergency light is automatically turned on for a certain time, so that the driver of the rear vehicle can be effectively informed that it is an emergency, thus contributing to the prevention of traffic accidents. Can be.
