특히, 야간에 주행을 하던중 도심지에서 주변이 밝을 경우 전조 등을 로우빔으로 조절하고, 아울러 주행 속도가 저속일 경우에도 로우 빔으로 조절하게 된다.In particular, while driving at night, when the surroundings are bright in the downtown area, the headlamps are adjusted to a low beam, and when the driving speed is low, the low beam is adjusted.
또한, 야간에 달리는 도중에도 상대방 차량의 전조등과 주행 속도에 따라 자주 전조등을 하이 빔과 로우 빔으로 조작해야 하는 불편함도 있었다.In addition, there is an inconvenience in that the headlights need to be frequently operated by the high beam and the low beam according to the headlights and the driving speed of the other vehicle even during the night running.
따라서 본 발명은 상기와 같은 종래 기술의 제반 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 차량 주변의 광량과 주행 속도에 따라 전조등을 제어하여 운전자의 편의를 도모 하도록 자동차의 전조등 제어장치를 제공함에 있다.Accordingly, the present invention is to solve the above problems of the prior art, an object of the present invention is to provide a headlight control device of the vehicle to control the headlights according to the amount of light and the traveling speed around the vehicle for the convenience of the driver. have.

제1도는 본 발명에 의한 자동차의 전조등 제어장치 구성도로서, 도시된 바와 같이, 자동차의 주행 속도를 감지하는 속도 센서(1)와, 상기 속도 센서(1)의 출력신호를 위상 반전 시키는 제1인버터(2)와, 차량 주변의 광량을 검출하는 조도 센서(3)와, 상기 조도 센서(3)의 출력신호를 위상 반전시키는 제2인버터(4)와, 상기 제2인버터(4)의 출력신호와 하이빔/로우빔 조절스위치(5)의 온/오프에 따른 신호를 논리곱하여 그 결과신호를 하이 빔(9) 제어신호로 출력하는 제1앤드게이트(6)와, 상기 앤드게이트(6)의 출력신호를 위상 반전 시키는 제3인버터(7)와, 상기 제3인버터(7)에서 출력되는 신호와 상기 제1인버터(7)의 출력신호를 논리곱하여 그 결과신호를 로우빔(10) 제어신호로 출력시키는 제2앤드게이트(8)로 구성 되었다.FIG. 1 is a block diagram of a headlight control apparatus for a vehicle according to the present invention. As shown in FIG. 1, a speed sensor 1 detecting a driving speed of a vehicle and a first phase inverting output signal of the speed sensor 1 are illustrated. An inverter 2, an illuminance sensor 3 for detecting the amount of light around the vehicle, a second inverter 4 for inverting the output signal of the illuminance sensor 3, and an output of the second inverter 4 A first end gate 6 which multiplies the signal according to the on / off signal of the high beam / low beam control switch 5 and outputs the result signal as a high beam 9 control signal, and the end gate 6 The third inverter 7 which phase-inverts the output signal of the output signal, the output signal of the third inverter 7 and the output signal of the first inverter 7, and the resultant signal to control the low beam 10. And a second end gate 8 for outputting a signal.
이와 같이 구성된 본 발명에 의한 자동차의 전조등 제어장치의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effect of the headlight control device of the vehicle according to the invention configured as described above are as follows.
먼저, 자동차가 주행되는 상태에서 야간에 전조등을 점등시키기 위해 운전자가 전조등 온/오프 스위치(도면에는 미도시)를 온시키면 속도 센서(1)는 현재 주행중인 차량의 속도를 검출하여 시속 15km이상이 되면 로우신호를 출력시키고 그 이하의 속도일 경우에는 로우빔을 오프시키기 위하여 하이신호를 출력시키게 된다.First, when the driver turns on the headlight on / off switch (not shown in the drawing) to turn on the headlight at night while the vehicle is running, the speed sensor 1 detects the speed of the vehicle currently being driven and is over 15 km per hour. If a low signal is output, the high signal is output to turn off the low beam.
이와 같이 속도 센서(1)에서 현재 주행중인 차량의 속도를 측정한 결과에 따른 신호(하이신호 또는 로우신호)는 제1인버터(2)에서 위상 반전된 후 제2앤드게이트(8)의 입력단에 인가되는데, 이때 차량의 주행속도가 15km이하일 경우에는 제2인버터(2)의 출력이 로우상태가 되므로 제2앤드게이트(8)는 타입력단의 출력과 관계없이 무조건 로우 빔(10)을 오프시키게 된다.As such, the signal (high signal or low signal) according to the result of measuring the speed of the vehicle currently driven by the speed sensor 1 is inverted in the first inverter 2 and then applied to the input terminal of the second and gate 8. In this case, when the driving speed of the vehicle is 15 km or less, since the output of the second inverter 2 is in a low state, the second and gate 8 unconditionally turns off the low beam 10 regardless of the output of the type force stage. do.
한편, 차량의 주행이 시작되면 조도 센서(3)는 차량 주변의 광량을 검출하게 되고, 그 검출결과 차량 주변의 광량이 설정치 이상이되면 하이빔을 오프시키기 위해 하이신호를 출력시키게 되고, 이와는 달리 차량 주변의 광량이 설정치 이하이면 하이빔을 구동시키기 위해 로우신호를 출력시키게 된다.On the other hand, when the driving of the vehicle starts, the illuminance sensor 3 detects the amount of light around the vehicle. If the amount of light around the vehicle exceeds the set value, the illuminance sensor 3 outputs a high signal to turn off the high beam. When the amount of light is less than the set value, the low signal is output to drive the high beam.
이와 같이 조도 센서(4)에서 출력되는 신호는 제2인버터(4)에서 위상 반전된 후 제1앤드게이트(6)의 입력단에 인가되며, 이때 제1앤드게이트(6)의 타입력단에는 사용자에의해 조작되는 로우빔/하이빔 조절스위치(5)의 조작에 대응하는 신호가 입력된다.As such, the signal output from the illuminance sensor 4 is inverted in phase from the second inverter 4 and then applied to the input terminal of the first and gate 6. A signal corresponding to the operation of the low beam / high beam adjustment switch 5 to be operated is input.
즉, 로우빔/하이빔 조절스위치(5)가 오프되면 이는 로우빔을 구동시키기 위한 신호로써 로우신호가 출력되고, 로우빔/하이빔 조절스위치(5)가 온되면 이는 하이빔을 구동시키기 위한 신호로써 하이신호가 출력된다.That is, when the low beam / high beam control switch 5 is turned off, this is a signal for driving the low beam, and a low signal is output. When the low beam / high beam control switch 5 is turned on, it is high as a signal for driving the high beam. The signal is output.
따라서 제1앤드게이트(6)는 입력되는 두 신호를 논리곱하여 그 결과치로 하이빔(9) 제어신호를 출력시키게 되는데, 조도 센서(3)에서 출력되는 신호가 주변 광량이 많은 신호, 즉 하이신호일 경우에는 제2인버터(4)의 출력신호가 로우신호가 되므로 상기한 로우빔/하이빔 조절스위치(5)의 조작과는 무관하게 제1앤드게이트(6)의 출력신호는 로우가 되어 하이빔(9)은 무조건 오프된다.Accordingly, the first gate 6 logically multiplies two input signals and outputs a high beam 9 control signal as a result value. When the signal output from the illumination sensor 3 is a signal having a large amount of ambient light, that is, a high signal, Since the output signal of the second inverter 4 becomes a low signal, the output signal of the first and gate 6 becomes low regardless of the operation of the low beam / high beam control switch 5 described above. Is turned off unconditionally.
이와는 달리 조도 센서(3)에서 출력되는 신호가 주변 광량이 적다는 신호, 즉 로우신호일 경우에는 제2인버터(4)의 출력신호가 하이신호가 되어 제1앤드게이트(6)의 출력신호는 로우빔/하이빔 조절스위치(5)가 온되어 있으면 하이신호를 출력시켜 하이빔(9)을 구동시키게 된다.On the other hand, when the signal output from the illuminance sensor 3 is a low ambient light signal, that is, a low signal, the output signal of the second inverter 4 becomes a high signal, and the output signal of the first and gate 6 is low. When the beam / high beam control switch 5 is turned on, a high signal is output to drive the high beam 9.
한편, 제1앤드게이트(6)의 출력신호는 제3인버터(7)에서 위상 반전된 후 제2앤드게이트(8)의 타 입력단에 인가되고, 이에 따라 제1앤드게이트(8)는 상기 제1인버터(2)에서 출력되는 신호와 타입력단에 입력되는 신호를 논리곱하여 그 결과신호를 로우빔(10) 제어신호로 출력시켜 로우빔을 제어하게 된다.On the other hand, the output signal of the first and gate 6 is phase-inverted at the third inverter 7 and then applied to the other input terminal of the second and gate 8, so that the first and gate 8 is The low beam is controlled by multiplying the signal output from the first inverter 2 with the signal input to the type force stage and outputting the resulting signal as the low beam 10 control signal.
다시 말해, 차량의 속도가 15km이하일 경우에는 로우 빔은 무조건 오프되고, 차량 주변의 광량이 설정치 이상일 경우에는 하이 빔이 무조건 오프된다.In other words, when the speed of the vehicle is 15 km or less, the low beam is unconditionally turned off, and when the amount of light around the vehicle is greater than or equal to the set value, the high beam is unconditionally turned off.
그리고 차량의 속도가 15km이하이고 주변 광량이 설정치 이상이 되면 로우빔(10)과 하이빔(9)이 모두 오프되는 것이다.When the speed of the vehicle is 15 km or less and the amount of ambient light is more than the set value, both the low beam 10 and the high beam 9 are turned off.
이상에서와 같이 본 발명은 차량 주변의 광량과 차량의 주행 속도에 따라 자동으로 전조등 제어가 가능 함으로써 시내 주행이나 서행시 그리고 차량 주변의 광량이 많은곳에서 운전자가 전조 등을 자주 온/오프 해야하는 불편함을 해소 시킬 수 있는 효과가 있다.As described above, according to the present invention, the headlight can be automatically controlled according to the amount of light around the vehicle and the driving speed of the vehicle. There is an effect that can be eliminated.
