본 고안은 보조 표시기를 이용한 차량의 주행속도 후방 표시장치에 관한 것으로서, 특히 후방 차량의 운전자에게 자기 차량의 주행속도등 각종 운행상태를 미리 인식시켜 줄 수 있는 차량의 주행속도 후방 표시 장치에 관한 고안이다.The present invention relates to a rear display apparatus for traveling speed of a vehicle using an auxiliary indicator, and more particularly, to a rear display apparatus for traveling speed of a vehicle capable of letting a driver of a rear vehicle recognize various driving conditions such as the traveling speed of his vehicle in advance. to be.
차량의 후방표시기는 자기차량의 운행 상태, 즉 제동, 방향전환등을 후방 차량의 운전자에 알림으로써 안전사고를 예방하고 차량 소통을 원활하게 하는데 중요한 몫을 담당하고 있다. 그런데 종래의 후방표시기로는 브레이크를 밟는 순간 점등되는 제동등(B), 야간에 켜두는 미등(T), 그리고 회전방향을 신호하는 방향전환등(W)이 있었다. 여기서 상기한 제동등(B)은 후방차량의 추돌사고를 방지하는데 매우 중요한 기능을 가지고 있지만, 그 설치위치가 낮은 곳에 위치하므로 실제 후방차량의 운전자가 쉽게 인식하기가 어려워서 전방차량의 제동등(B)이 켜짐과 동시에 신속히 대처하지 못함으로써 추돌하는 사고가 많이 발생하고 있는 실정이다.The rear indicator of the vehicle plays an important part in preventing the safety accident and smoothing the vehicle communication by informing the driver of the rear vehicle of the driving status of the vehicle, that is, the braking and the turning direction. However, the conventional rear indicators include a brake light B that is turned on at the moment of brake, a tail light T that is turned on at night, and a turn signal W that signals a rotational direction. Here, the braking light (B) has a very important function to prevent the collision of the rear vehicle, but since the installation position is low, it is difficult for the driver of the actual rear vehicle to easily recognize the brake light (B) of the front vehicle At the same time, many accidents occur due to inability to respond quickly.
이에 따라 종래에는 뒷 좌석 후방에 별도의 보조표시기(A')를 설치하여 이를 제동등(B)과 연동 시킴으로써 후방차량에 브레이크의 조작상태를 더 쉽게 인식시키고자 하였다.Accordingly, in the related art, a separate auxiliary indicator A 'is installed at the rear of the rear seat to link the brake light B to the rear vehicle to more easily recognize the operating state of the brake.
그런데 추돌사고의 원인이 대개 안전거리 확보 그리고 차간거리가 좁혀질때 급정거 할 수 있도록 서행 운전 등의 안전수칙을 지키지 않는데 그 원인이 있겠으나 그 외에 전방 차량의 현재주행 속도 및 자기차량의 현재 주행속도 등 각종 운행상태를 파악하지 못하고 돌방사태등에 미리 대비하지 못한데서 오는 원인도 크다. 따라서 전방차량의 현재 주행속도와 기타 가속여부등을 미리 알고 있다면 자기 차량의 주행속도 등에 따라 방어운전을 함으로써 추돌사고를 방지할 수 있게될 것이다.However, the cause of a collision accident is usually not to observe safety rules such as slow driving to secure a safe distance and to suddenly stop when the distance between cars is narrowed, but there are other causes such as the current driving speed of the vehicle ahead and the current driving speed of the own vehicle. There are also many reasons for not being able to grasp various driving conditions and not preparing for unexpected events. Therefore, if you know in advance the current driving speed and other acceleration of the vehicle ahead of you will be able to prevent the collision by defensive driving according to the driving speed of the vehicle.
이와 같은 관점에서는 상기와 같은 종래의 후방 표시기나 보조표시기는 안전주행에 적절한 신호를 후방 차량에 제공하지 못하였던 문제점이 있었던 것이다.In view of the above, there is a problem in that the conventional rear indicator and the auxiliary indicator do not provide a signal suitable for safe driving to the rear vehicle.
본 고안은 상술한 종래의 문제점을 감안하여 차량의 주행속도등이 표시되는 차량의 주행속도 후방표시장치를 제공하는 것을 목적으로 한다.An object of the present invention is to provide a driving speed rear display device of a vehicle in which the traveling speed of the vehicle is displayed in view of the above-described conventional problems.
상기 목적을 달성하기 위하여 본 고안에서는 차량의 구동축의 회전을 검지하여 펄스신호를 출력하는 회전속도 검지부와, 상기 매 펄스 신호로부터 회전속도에 비례하는 전압을 출력하는 주행속도 연산부와, 이 주행속도 연산부에 의해 상기 회전속도에 비례하는 전압으로 구동되어 보조표시기에 설치된 속도표시부에 구동신호를 순시적으로 보내는 속도표시 구동부를 설치하여 되는 것을 특징으로 한다. 이하 첨부된 도면을 참조하여 본 고안 실시예를 상세히 설명한다.In order to achieve the above object, the present invention detects the rotation of the drive shaft of the vehicle and outputs a pulse signal, a traveling speed calculating unit for outputting a voltage proportional to the rotating speed from each pulse signal, and the traveling speed calculating unit. It is characterized in that the speed display drive unit is driven by a voltage proportional to the rotational speed to instantaneously send a drive signal to the speed display unit installed in the auxiliary display. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안의 일실시예로서, 도시하지 않은 차량의 구동축의 회전을 검지하여 그 회전속도에 따라 주기가 변화하는 펄스신호를 출력하는 회전속도검지부(1)가 설치되고, 상기 회전속도 검지부(1)의 출력단에는 상기 매펄스신호 주기(주파수)를 전압레벨로 변환하여 주행속도로 연산된 출력신호를 발생 하는 주행속도 연산부(2)가 연결되며, 상기 주행속도 연산부(2)의 출력단에서 상기 출력신호로 구동되어 그 입력신호에 따른 구동신호를 속도 표시부(11)에 보내는 속도표시 구동부(3)가 연결되어 구성된다. 여기서 속도표시부(11)는 보조표시기(A)에 설치되며, 상당한 거리의 후방차량에 충분히 인식될수 있는 크기와 광도를 제공하도록 LED 등 적절한 발광소자의 열(array)로 구성되는 것이 바람직하다.2 is an embodiment of the present invention, the rotational speed detection unit (1) for detecting the rotation of the drive shaft of the vehicle (not shown) and outputs a pulse signal of which the period changes according to the rotational speed is provided, the rotational speed detection unit The output terminal of (1) is connected to the traveling speed calculation unit 2 for converting the every pulse signal period (frequency) into a voltage level to generate an output signal calculated at the traveling speed, and at the output terminal of the traveling speed calculation unit 2 The speed display driver 3 which is driven by the output signal and sends a driving signal according to the input signal to the speed display unit 11 is connected. In this case, the speed display part 11 is installed in the auxiliary display A, and is preferably composed of an array of suitable light emitting elements such as an LED so as to provide a size and brightness that can be sufficiently recognized in a rear vehicle of a considerable distance.
이와 같은 본 고안 장치의 작동은 상기 회전속도 검지부(1)에서 구동축의 회전에 따라 펄스간의 주기가 변화하는 펄스신호를 출력하면, 상기 주행속도 연산부(2)에서는 상기 매 펄스신호의 주기 즉 변화하는 주파수를 전압으로 변환하여 주행속도에 상응하는 증감 파형의 출력 신호를 발생한다. 다음 이 신호에 따라 속도 표시구동부(3)가 동작하여 상기 속도표시부(11)에는 차량의 현재 주행속도가 표시된다.The operation of the device of the present invention outputs a pulse signal in which the period between pulses changes in accordance with the rotation of the drive shaft in the rotational speed detection unit 1, and the traveling speed calculating unit 2 changes the period, i.e., every pulse signal. The frequency is converted into a voltage to generate an output signal of increasing and decreasing waveforms corresponding to the traveling speed. Next, the speed display driver 3 is operated in accordance with this signal, and the speed display unit 11 displays the current running speed of the vehicle.
제3도는 본 고안의 다른 실시예로서 상기 실시예의 본 고안 장치에 가속표시부(12)를 구비 하는데, 가속표시부(12)를 증속표시등(12a)과 감속표시등(12b)으로 구분시켜 상기 주행속도 연산부(2)와 상기 가속표시부(12)사이에 가속도 연산부(4) 및 가속 표시 구동부(5)를 연결시킨 구성이다.3 is another embodiment of the present invention, which includes an acceleration display unit 12 in the inventive device of the above embodiment, wherein the acceleration display unit 12 is divided into a speed increase indicator 12a and a deceleration indicator 12b. The acceleration calculating unit 4 and the acceleration display driving unit 5 are connected between the speed calculating unit 2 and the acceleration displaying unit 12.
상기 실시예에서는 상기 주행속도 연산부(2)의 출력중 어느 싯점의 출력신호와 그 이전의 출력신호를 비교 출력하는 상기 가속도 연산부(4)의 출력단에 하이(high)신호가 출력되면 상기 가속표시 구동부(5)의 일측 출력단이 하이로 되고 그 타측 출력단은 로우(low)로 되어 상기 가속표시부(12)의 증속표시등(12a)이 점등되고 반대로 상기 가속도 연산부(4)에서 로우신호가 출력되면 상기 가속표시 구동부(5)의 타측 출력단이 하이로 되어 감속표시등(12b)이 점등된다. 물론 일정속도가 감지되면 가속도 연산부(4)의 출력은 "0"이 되므로 이때에는 가속표시 구동부(5)가 동작하지 않는다. 따라서 차량의 주행속도가 그 주행 속도표시부(11)에 표시됨과 동시에 가속시에는 증속표시등(12a)이, 감속시에는 감속표시등(12b)이 각각 점등되므로 현재의 주행속도와 함께 그 속도가 가속되고 있는지의 여부를 쉽게 알아차릴 수 있게 된다.In the above embodiment, when a high signal is output to an output terminal of the acceleration calculating unit 4 comparing and outputting an output signal of a certain point among the outputs of the traveling speed calculating unit 2 and the previous output signal, the acceleration display driving unit When one output terminal of (5) becomes high and the other output terminal becomes low (low) so that the acceleration indicator 12a of the acceleration display unit 12 lights up, on the contrary, when the low signal is output from the acceleration calculating unit 4, The other output terminal of the acceleration display driver 5 goes high, and the deceleration indicator 12b lights up. Of course, if the constant speed is detected, the output of the acceleration calculator 4 becomes "0", and thus the acceleration display driver 5 does not operate at this time. Therefore, the driving speed of the vehicle is displayed on the driving speed display section 11, and the speed increase indicator 12a lights up at the time of acceleration, and the deceleration indicator 12b lights up at the time of deceleration. You can easily tell whether it is being accelerated or not.
또한 제3도에서 본 고안 후방표시장치에는 기존 제동등(B)을 보조하는 제동표시부(13)가 구비되는데 이는 상기 제동등(B)과 병렬접속되어 통상과 같이 브레이크를 밟는 순간 점등됨으로써 제동중임을 보조적으로 알려주는 것이다.In addition, the rear display device of the present invention in FIG. 3 is provided with a braking display portion 13 to assist the existing braking light B, which is connected in parallel with the braking light B so that it is turned on when the brake is applied as usual. To inform.
제4도는 본 고안 후방표시장치의 표시부들이 설치되는 보조표시기의 일례인데 이 보조표시기(A)의 중앙에는 주행 속도를 숫자로 표시케하는 본 고안장치의 주행속도 표시부(11)가 배치되고, 그 상하부에 증속표시등(12a)과 감속표시등(12b)이 배치되며, 보조표시기(A)의 둘레에는 보조제동등(13)이 배치 구성된 것이다.4 is an example of an auxiliary display in which the display units of the rear display device of the present invention are installed. In the center of the auxiliary display A, the traveling speed display unit 11 of the present invention device which displays the traveling speed numerically is disposed. The speed increase indicator 12a and the deceleration indicator 12b are arranged above and below, and the auxiliary brake light 13 is arranged around the auxiliary indicator A.
또한 상기 보조제동등(13)은 기존의 제동등과 같은 적색등으로 하고, 증속표시등(12a)은 녹색 그리고 감속표시등(12b)은 적색 또는 황색등으로 형성하는 것이 바람직하다.In addition, it is preferable that the auxiliary brake light 13 is formed of a red light like the conventional brake light, the speed increase indicator 12a is green, and the deceleration indicator 12b is formed of red or yellow light.
이와 같이 본 고안에 의하면 자기차량의 현재 주행속도를 비롯하여 증속, 감속 상태등 운행상태를 후방차량의 운전자에게 미리 알려줄 수 있는 바, 후방차량의 운전자는 상기 전방차량의 주행속도에 맞추어 안전한 (적어도 추월하지 않는) 속도로 주행할 수 있고 또 그 증속, 감속 상태를 미리 확인할 수 있으므로 돌발 사태에 대비 효과적으로 방어운전을 유행함으로써 추돌사고등 각종 사고를 미연에 방지할 수 있는 지극히 효과적인 고안인 것이다.Thus, according to the present invention, it is possible to inform the driver of the rear vehicle in advance of the driving speed of the vehicle, including the current driving speed of the vehicle, such as a speed increase and a deceleration state. It is possible to drive at a speed, and to check the speed and deceleration status in advance, so it is a very effective design that can prevent various accidents such as collision accidents by prevalent defensive driving in preparation for an accident.
