자동차의 야간주행시에 교통 신호 또는 혼잡으로 자동차가 주행과 정지를 반복하는 경우, 정지시에는 헤드램프를 오프하고, 출발시 다시 헤드램프를 온하는 단순동작을 반복해야 하는 번거로움이 있었다.When the car repeatedly runs and stops with a traffic signal or congestion during night driving of the car, it is troublesome to repeat the simple operation of turning off the head lamp and stopping the head lamp again when starting.
본 고안은 상기한 사정을 감안해서 안출된 것으로, 자동차가 정지하면 이를 엔진의 회전수를 매개로 감지하여 자동으로 헤드램프를 오프하는 한편 출발시에는 헤드램프를 온시킴으로써 편리성을 향상시킨 자동차의 헤드램프 제어장치를 제공함에 그 목적이 있다.The present invention has been devised in view of the above circumstances, and when the vehicle is stopped, it detects this by the engine speed and automatically turns off the head lamp, while turning on the head lamp at the start of the The object is to provide a headlamp control device.
상기 목적을 달성하기 위한 본 고안의 자동차의 헤드램프 제어장치는 디스트리뷰터로부터 인출한 엔진의 회전수에 비례하는 펄스신호를 증폭하는 증폭부와, 증폭된 펄스신호에서 고주파 잡음을 제거하는 필터부, 헤드램프의 온/오프에 대한 제어레벨을 설정함과 더불어 설정된 제어레벨에 따라 엔진회전수의 감지신호를 생성하는 제어신호부 이 제어신호부의 제어신호에 따라 하이/로우레벨의 신호를 출력하는 타이머 회로부, 이 타이머 회로부의 출력신호에 따라 온/오프 동작하면서 각각 다른 접점에 접속되어 헤드램프를 온/오프하는 릴레이부를 포함하여 구성된 것을 특징으로 한다.In order to achieve the above object, the headlamp control apparatus of a vehicle of the present invention includes an amplifier for amplifying a pulse signal proportional to the number of revolutions of an engine drawn from a distributor, a filter unit for removing high frequency noise from an amplified pulse signal, and a head. A control signal unit for setting the control level for the lamp on / off and generating a detection signal of the engine speed according to the set control level. The timer circuit unit outputs a high / low level signal according to the control signal of the control signal unit. And a relay unit connected to different contacts while the on / off operation is performed according to the output signal of the timer circuit unit.
상기 구성으로 된 본 고안에 의하면, 자동차가 정지하여 디스트리뷰터에서 낮은 주파수의 펄스신호가 인출되는 경우에 상기 타이머 회로부에서 하이레벨의 신호가 상기 릴레이부로 출력되어 헤드램프가 오프됨과 더불어, 자동차가 출발하여 상기 디스트리뷰터에서 높은 주파수의 펄스신호가 인출되면 헤드램프가 온되게 된다.According to the present invention having the above configuration, when the vehicle is stopped and the pulse signal of low frequency is drawn from the distributor, a high level signal is output from the timer circuit unit to the relay unit, and the head lamp is turned off, When the pulse signal of the high frequency is drawn from the distributor, the head lamp is turned on.
이하, 도면을 참조하여 본 고안의 실시예를 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the drawings.
제1도는 본 고안의 1실시예에 따른 자동차의 헤드램프 제어장치의 구성을 나타낸 회로도로서, 도면에서 참조번호 1은 자동차의 디스트리뷰터로부터 인출되는 엔진의 회전수에 비례하는 펄스신호를 증폭하는 증폭부이고, 2는 이 증폭부의 펄스신호에서 고주파 잡음을 제거하기 위한, 예컨대 LPF(Low Pass Filter)로 이루어진 필터부, 3은 헤드램프를 온/오프하기 위한 제어레벨을 설정함과 더불어 엔진 회전수를 감지하여 감지신호를 생성하는 제어신호부, 4는 제어신호에 따라 하이/로우레벨의 신호를 출력하는 타이머 회로부, 5는 이 타이머 회로부(4)의 출력신호에 따라 온/오프되면서 각각 다른 접점에 접속되는 릴레이부이다. 이러한, 제1도의 회로구성에 있어서, 야간주행시 교통혼잡이나 정지신호등으로 자동차가 정지하면 상기 디스트리뷰터에서는 낮은 주파수의 펄스신호가 인출되는 바, 이 펄스신호는 상기 필터부(2)를 거쳐 상기 제어신호부(3)의 가변저항(VR)에 전압신호로 인가된다. 이 제어신호부(3)의 트랜지스터(Q1)가 온/오프되는 상기 펄스신호의 레벨은 상기 가변저항(VR)의 값을 조정함에 따라 변경할 수 있다. 이 제어신호부(3)의 감지신호는 상기 트랜지스터(Q1)의 온/오프에 따라 생성된다. 즉, 상기 디스트리뷰터의 펄스신호에 의한 상기 가변저항(VR)의 전압이 소정레벨 이하(즉, 자동차가 정지한 상태)로 되면, 상기 제어신호부(3)의 트랜지스터(Q1)가 오프되며, 그에 따라 Vcc 전원이 제1도의 LPF를 거쳐 상기 타이머 회로부(4)로 입력된다. 이때 타이머 회로부(4)는 저항(R6)과 캐패시터(C3)의 시정수에 따라 결정되는 일정 시간 만큼 대기한 후, 하이레벨의 신호를 상기 릴레이부(5)로 출력하며 그에 따라 릴레이의 스위치가 이 헤드램프를 오프하는 접점(A)에 접속된다. 즉, 상기 타이머 회로부(4)가 일정한 대기시간을 갖기 때문에 자동차가 일시적으로 정지하는 경우에는 헤드램프가 꺼지지 않는다.FIG. 1 is a circuit diagram showing the configuration of a headlamp control apparatus for a vehicle according to an embodiment of the present invention. In the drawing, reference numeral 1 denotes an amplifier for amplifying a pulse signal proportional to the number of revolutions of an engine drawn from a distributor of an automobile. 2 is a filter part for removing high frequency noise from the pulse signal of this amplifier part, for example, a filter part composed of a low pass filter (LPF), and 3 is an engine speed while setting a control level for turning on / off the head lamp. A control signal unit for sensing and generating a detection signal, 4 is a timer circuit unit for outputting a high / low level signal according to the control signal, 5 is turned on / off in accordance with the output signal of the timer circuit unit 4 to each other contact point Relay section to be connected. In the circuit configuration of FIG. 1, when the vehicle is stopped due to a traffic congestion or a stop signal during night driving, a pulse signal of a low frequency is extracted from the distributor, and the pulse signal is passed through the filter unit 2 to the control signal. It is applied to the variable resistor VR of the unit 3 as a voltage signal. The level of the pulse signal at which the transistor Q1 of the control signal section 3 is turned on / off can be changed by adjusting the value of the variable resistor VR. The detection signal of this control signal section 3 is generated in accordance with the on / off of the transistor Q1. That is, when the voltage of the variable resistor VR due to the pulse signal of the distributor falls below a predetermined level (that is, the vehicle is stopped), the transistor Q1 of the control signal unit 3 is turned off. Accordingly, the Vcc power source is input to the timer circuit section 4 via the LPF of FIG. At this time, the timer circuit unit 4 waits for a predetermined time determined according to the time constants of the resistor R6 and the capacitor C3, and then outputs a high level signal to the relay unit 5, whereby the switch of the relay It is connected to the contact A which turns off this head lamp. That is, the headlamp does not turn off when the vehicle is temporarily stopped because the timer circuit 4 has a constant waiting time.
또한, 자동차가 출발하면, 상기 디스트리뷰터에서는 높은 주파수의 펄스신호가 인출되고, 그에 따라 상기 제어신호부(3)의 트랜지스터(Q1)가 온되며, 그에 따라 상기 타이머 회로부(4)에는 로우레벨의 신호가 입력된다. 이때 타이머 회로부(4)는 곧바로 로우레벨의 신호를 상기 릴레이부(5)에 인가하며, 그에따라 릴레이의 스위치는 헤드램프를 온하는 접점(B)에 접속된다. 따라서 자동차가 출발하면 곧바로 헤드램프가 켜지게 된다.In addition, when the vehicle starts, the distributor outputs a pulse signal of a high frequency, and accordingly, the transistor Q1 of the control signal part 3 is turned on, so that the timer circuit part 4 has a low level signal. Is input. At this time, the timer circuit section 4 immediately applies a low level signal to the relay section 5, whereby the switch of the relay is connected to the contact point B for turning on the headlamp. Therefore, the headlamps are turned on as soon as the vehicle starts.
이상에서 설명한 바와 같이, 본 고안에 의하면 교통혼잡이나 신호 등으로 인하여 야간운행중인 자동차가 정지하면, 헤드램프가 오프되고, 자동차가 출발하면 온되는 자동차의 헤드램프 제어장치가 실현된다.As described above, according to the present invention, the head lamp is turned off when the car in night operation is stopped due to traffic congestion or a signal, and the head lamp control device for the car is turned on when the car starts.
또한 본 고안은 상기 실시예에 한정되지는 않으며 본원 발명의 기술적 요지를 벗어나지 않는 범위내에서 변형실시할 수 있다.In addition, the present invention is not limited to the above embodiment and can be modified within the scope without departing from the technical spirit of the present invention.
