자동차의 속도표시등 {Automotive Speed Indicator}Automotive Speed Indicator {Automotive Speed Indicator}

본 고안은 자동차의 전면의 지붕위쪽에 설치되는 다수의 LED등 중 점등되는 LED등의 수를 통해 주행속도를 표시함으로써 주변에서 주행하는 차량의 차속판단을 통해 차선변경시 안전에 유의할 수 있도록 하는 자동차의 속도표시등에 관한 것이다.The present invention relates to an automobile which displays driving speed through the number of LEDs or the like which are lit up among a plurality of LEDs installed on the roof of the front of the automobile, Of the speed indicator.

일반적으로 자동차에는 운전석 전면의 인스트루먼트 패널에 차량의 운전상태를 표시하는 각종 계기와 경고등 등이 설치되어 운전자가 자체 차량의 주행속도나 엔진의 회전수를 비롯하여 차량의 이상여부를 인지할 수 있도록 되어 있다.Generally, in an automobile, various instrument and warning lamps for indicating the driving state of the vehicle are installed on the instrument panel on the front of the driver's seat so that the driver can recognize the driving speed of the vehicle, the number of revolutions of the vehicle, .

또한 도로상에서 주행하는 차량간에 자기 차량의 변화에 대해 타 차량에 알려주기 위한 신호로서, 차체의 전후좌우 모서리에 턴시그날램프가 설치되어 운전자의 턴시그날램프 스위치조작에 따라 좌측 턴시그날램프 또는 우측 턴시그날램프가 점멸되도록 이루어져 있고, 운전자가 상기 턴시그날램프 스위치와는별도로 설치된 비상등 스위치를 조작하게 되면 좌,우측 턴시그날램프가 동시에 점멸되어 위급상황이 발생되었음을 전후방에 주행하는 차량에 알려줄 수 있도록 되어 있다.A turn signal lamp is provided on the front, rear, right, and left corners of the vehicle body as a signal for informing other vehicles about the change of the own vehicle among the vehicles traveling on the road, and the left turn signal lamp or the right turn The signal lamp is turned on and when the driver operates the emergency light switch installed separately from the turn signal lamp switch, the left and right turn signal lamps are flashed simultaneously to inform the vehicle traveling in the front and rear that an emergency has occurred .

이와 같은 턴시그날램프 작동 스위치를 통상 컴비네이션스위치라 부르며, 운전자가 차선을 변경하고자할 때나 방향을 변경시키고자 할 때 작동시키도록 된 것이다. 따라서 통상 주행중 운전자가 차선변경을하고자 할 경우 컴비네이션스위치를 작동시켜 턴시그날램프를 작동시킨 후 차선을 변경하게 되면 변경차선에서 주행하고 있던 차량은 앞차량의 턴시그날램프의 점멸상태를 보고 속도를 줄이거나 하여 그에 대비한 운전을 함으로써 추돌사고를 방지하고 있다.Such a turn signal lamp operation switch is called a normal combination switch and is operated when the driver wishes to change the lane or to change the direction. Therefore, if the driver wishes to change lanes during normal driving, if the turn signal lamp is operated by operating the combination switch and then the lane is changed, the vehicle traveling in the change lane will see the turn signal lamp of the front vehicle, By doing so, we prevent the collision accident.

주행중 차선변경을 할때에는 차량의 실내에 설치되는 룸미러나 외측에 설치되는 백미러를 통해후방을 주시하여 변경하고자 하는 차선의 인접된 후방에서 차량이 주행해 오고 있는지 여부를 판단하고,만약 후방 가까이서 달려오고 있는 차가 없다면 바로 차선을 변경해도 상관없지만 백미러에 차량이 보이는 경우 차선을 변경할 것인지 여부를 망설이게 된다. 즉, 룸미러나 백미러 만으로 뒷차가 빨리오는지느리게 오는지 판단하기 어렵기 때문이며, 뒷차가 빨리 달려오고 있는데도 불구하고 차선변경을 하게 되면 뒷차는 충분한 감속거리나 제동거리를 확보하지 못하여 추돌사고가 발생할 수 있는 경우가 많다. 이는 옆차선의 후방에서 주행해 오는 차의 속도를 순간적으로 판단하기 어렵기 때문이다.이와는 반대로 뒷차가 저속으로 주행하고 있음에도 이를 알지 못하여 차선변경을 하지 못하는 경우도 있는데, 교차로 근방에서 이러한 상황에 직면하게 되면 목적한 바와는 다른 길로 빠져버릴 수 있다.본 고안은 상기한 제반 사정을 감안하여 안출한 것으로, 차량마다 주행속도를 표시할 수 있는 표시수단을 차량의 전면부에 설치함으로써 주행중 룸미러나 백미러를 통해 이러한 주행속도 표시수단을 확인하기만 해도 어느 정도 그 차의 주행속도를 판단할 수 있게 되고, 그에 따라 자기 차량의 주행속도와 비교하여 차선변경시 안전한지 여부를 용이하게 그리고 신속하게 확인할 수 있도록 된 자동차의 속도표시등을제공하고자 함에 고안의 목적이 있다.When changing a lane during driving, it is judged whether or not the vehicle is running from the adjoining rear side of the lane to be changed by looking at the rear through a room mirror installed in the interior of the vehicle or a rearview mirror installed outside, If you do not have a car coming, you can change the lane right away, but if you see a car in the rearview mirror, you will be wondering if you want to change the lane. In other words, it is difficult to judge whether the rear car is coming quickly or slowly due to a room mirror or a rearview mirror. Even if the rear car is running fast, if the lane change is made, the rear car can not secure sufficient deceleration distance or braking distance, There are many cases. This is because it is difficult to instantly judge the speed of the car traveling from the rear of the next lane. In contrast, there is a case where the rear lane is traveling at low speed and it is not possible to change the lane because it is unknown. The present invention is conceived in view of the above circumstances and it is an object of the present invention to provide a display device capable of displaying the traveling speed for each vehicle on the front part of the vehicle, It is possible to determine the running speed of the vehicle to a certain extent only by confirming the running speed display means through the rearview mirror so that it can be easily and quickly checked whether the lane change is safe in comparison with the running speed of the own vehicle The present invention is intended to provide a speed indicator of an automobile which can be provided.

상기한 목적을 실현하기 위한 본 고안은 차량의 전면부 예컨대 좌,우측 헤드램프 사이에 다수의 속도표시용 램프를 일렬로 설치하고, 차속을 감지할 수 있는 차속센서를 구비하는 한편 상기 차속센서가 감지한 차속신호를 입력받아 그 후단에 연결되는 릴레이의 접속접점을 변경시켜 차속신호에 따라 상기 속도표시용 LED등을 작동시킬 수 있는 제어신호를 송출하는 콘트롤러로 이루어져 있으며, 차속의 빠르기에 따라 점등되는 LED등의 수를 달리하여 차속을 표시하도록 이루어진 것이다.
In order to achieve the above object, the present invention provides a vehicle speed sensor comprising a plurality of speed display lamps arranged in a line between a front portion of a vehicle, e.g., a left and a right headlamp, And a controller for receiving a sensed vehicle speed signal and changing a connection point of a relay connected to the rear end thereof to transmit a control signal for operating the speed indicating LED according to a vehicle speed signal. The number of LEDs or the like is varied to display the vehicle speed.

본 고안은 전방에서 주행하고 있는 차량의 운전자는 백미러나 룸미러를 통해 후방에서 주행해 오는 차량의 주행속도를 판단할 때 점등된 램프의 수를 보고 알 수 있게 된다.The present invention allows a driver of a vehicle traveling from the front to see the number of lamps illuminated when determining the traveling speed of a vehicle traveling from the rear through a rearview mirror or a room mirror.

상기한 바와 같이 본 고안은 차량의 전면에 차속을 표시할 수 있도록 다수의 LED등를 설치하고 주행중 차속의 감지에 따라 상기 LED등들의 점등을 제어함으로써 차선을 변경하고자 할때 백미러나 룸미러를 통해후방 주행차량의 상기 LED등 즉 속도표시등을 확인하게 되면 후방 주행 차량의 속도를 판단할 수 있게 되어 보다 안전하게 차선변경을 할 수 있는 효과가 있다. 설치하고 주행중 차속의 감지에 따라 상기 LED등들의 점등을 제어함으로써 차선을 변경하고자 할때 백미러나 룸미러를 통해후방 주행차량의 상기 LED등 즉 속도표시등을 확인하게 되면 후방 주행 차량의 속도를 판단할 수 있게 되어 보다 안전하게 차선변경을 할 수 있는 효과가 있다.
As described above, in the present invention, a plurality of LEDs or the like are provided to display a vehicle speed on a front surface of a vehicle, and when the lane is to be changed by controlling the lighting of the LEDs according to the detection of vehicle speed during driving, If the LED or the speed indicator of the driving vehicle is checked, the speed of the rear driving vehicle can be determined, so that it is possible to change the lane more safely. And the LEDs of the rear driving vehicle or the speed indicator are checked through the rearview mirror or the room mirror in order to change the lane by controlling the lighting of the LEDs according to the detection of the vehicle speed during driving, So that it is possible to change the lane more safely.

본 고안의 바람직한 일실시예에 대한 구성 및 작용효과에 대하여 예시도면에 의거하여 상세히 설명하면 다음과 같다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 차량의 주행속도를 감지하는 차속센서(10)에 콘트롤러(12)를 연결하고, 상기 콘트롤러(12)의출력단에는 제1∼제4 릴레이구동부(14∼20)를 매개로 속도표시용 LED등(L1∼L4)가 연결되며, 상기 콘트롤러(12)는 차속센서(10)를 통해 감지되는 차속신호의 크기에 따라 스위칭되는 제1∼제4 릴레이구동부(14∼20)의 수를 달리 하여 점등되는 등의 수를 제어하도록 연결된 구조로 되어 있다.The controller 12 is connected to a vehicle speed sensor 10 that senses the running speed of the vehicle and is connected to the output terminal of the controller 12 via a first to fourth relay driving units 14 to 20 for speed indication LEDs L1 to L4 are connected to the controller 12. The controller 12 controls the number of the first to fourth relay drivers 14 to 20 to be switched according to the magnitude of the vehicle speed signal sensed through the vehicle speed sensor 10, So that the number of lights to be turned on is controlled.

도 1은 본 고안에 따른 자동차의 속도표시등에 대한 구성도를 도시한 것이다.FIG. 1 is a block diagram of a vehicle speed indicator according to the present invention.

차속센서(10)는 주행중 차량의 주행속도를 감지하여 이를 콘트롤러(12)로 송출하도록 이루어진 것이다.The vehicle speed sensor 10 senses the running speed of the vehicle during driving and sends the detected speed to the controller 12. [

콘트롤러(12)는 상기 차속센서(10)를 통해 입력되는 데이타 즉 차속신호에 따라 그 후단에 연결되는 제1∼제4 릴레이구동부(14∼20)의 스위칭을 제어하는 제어신호를 송출하도록 이루어진 것이다.The controller 12 is configured to transmit a control signal for controlling the switching of the first to fourth relay driving units 14 to 20 connected to the rear end thereof in accordance with the data input through the vehicle speed sensor 10 .

본 고안에서는 차량의 속도를 일례로서 4단계로 나누어 표시하도록 된 것이기 때문에 콘트롤러(12)의 출력단에 릴레이구동부가 4개 연결되고 그 릴레이구동부에 각각 속도표시를 위한 등이 연결되어 있으나,이는 본 고안의 작용을 이해하기 쉽게 설명하기 위한 것으로, 필요에 따라 그 수를 증가 또는 감소시켜 설치할 수도 있는 것이다. 제1∼제4 릴레이구동부(14∼20)에 연결되어 있는 속도표시용 LED등(L1∼L4)는 예시도면 도 2에 도시된 바와 윈드 스크린 위쪽 지붕에 설치되어 있는데, 이는 반드시 지붕쪽에 설치되어야 하는 것은 아니고 전방에서 주행하고 있는 차량의 운전자가 룸미러나 백미러를 통해 용이하게 확인할 수 있는 위치에 설치하여도 좋다.In the present invention, since the speed of the vehicle is divided into four levels and displayed, for example, four relay driving parts are connected to the output terminal of the controller 12, and the relay driving parts are connected to the relay driving part for speed indication. To easily understand the operation of the apparatus, and the number of the apparatus may be increased or decreased as needed. The speed indicating LEDs (L1 to L4) connected to the first to fourth relay driving units 14 to 20 are installed on the upper roof of the windscreen as shown in FIG. 2, But may be provided at a position where a driver of a vehicle running in front of the vehicle can easily confirm the vehicle through a room mirror or a rearview mirror.

이와 같이 설치되는 LED등(L1∼L4)들의 점등을 통해 차속을 표시하게되는 바, 콘트롤러(12)에서 릴레이구동부(14∼20)의 스위칭을 제어함으로써 램프(L1∼L4)들의 점등을 제어하게 된다. 즉, 차속이 0∼30 Km/h 사이에 있는 것으로 감지되는 경우 LED등(L1)만을 점등시키고, 차속이 30 내지 60Km/h 사이에 있는 것으로 감지되는 경우 LED등(L1)와 LED등(L2)를 점등시키며, 차속이 60 내지 90 Km/h 사이에 있는 것으로 감지되는 경우 LED등(L1)를 비롯하여 LED등(L2)와 LED등(L3)를 점등시킨다. 그리고 차속이 90 Km/h 이상인 고속인 경우에는 4개의 LED등(L1∼L4)가 모두 점등시킨다. 그리하여 전방에서 주행하고 있는 차량의 운전자는 백미러나 룸미러를 통해 후방에서 주행해 오는 차량의 주행속도를 판단할 때 점등된 LED등의 수를 보고 알 수 있게 된다.The controller 12 controls the switching of the relay driving units 14 to 20 so as to control the lighting of the lamps L1 to L4 by turning on the LEDs L1 to L4, do. That is, when it is detected that the vehicle speed is within the range of 0 to 30 Km / h, only the LEDs L1 are turned on, and when it is detected that the vehicle speed is within the range of 30 to 60 km / h, When the vehicle speed is detected to be in the range of 60 to 90 Km / h, the LED lamp L1, the LED lamp L2 and the LED lamp L3 are turned on. When the vehicle speed is 90 Km / h or higher, all four LEDs (L1 to L4) are turned on. Thus, the driver of the vehicle traveling in front of the vehicle can see the number of the LEDs and the like illuminated when judging the traveling speed of the vehicle traveling from the rear through the rearview mirror or the room mirror.
