[산업상 이용 분야][Industrial use]
본 고안은 차량의 주행속도 표시지침과 핸들조향각도 지침을 계기판에 병행 설치하여 볼 수 있도록 하는 주행속도별 조향핸들 표시장치에 관한 것이다.The present invention relates to a steering wheel display device for each driving speed to be installed in parallel to the vehicle speed display guideline and steering wheel steering angle guideline.
[종래기술][Private Technology]
종래 주행속도 표시계기판은 제5도에 도시한 바와같이 계기판(11)에 속도표시숫자(12)와 주행속도 표시지침(13)으로 이루어져 주행속도에 따라 주행속도 표시지침이 속도표시숫자를 가르키도록 되어있다.As shown in FIG. 5, the conventional speed display instrument panel includes a speed display number 12 and a travel speed display guide 13 on the instrument panel 11 to indicate the speed display number according to the travel speed. It is.
[종래기술의 문제점][Problems with Prior Art]
종래 주행속도 표시계기판은 상술한 바와같이, 차량의 주행속도에 따라 주행속도 표시지침이 속도표시숫자를 가르키도록만 되어있어 특히, 커브길 운전시 조향핸들 각도와 자동차 진행속도가 맞지 않아 안전사고를 발생할 염려가 많다.As described above, the conventional driving speed display instrument board is designed to indicate the speed display number according to the driving speed of the vehicle. In particular, the steering wheel angle and the driving speed do not match when driving on a curved road. There is a lot of concern.
즉, 핸들의 각도가 큰데도 불구하고, 자동차 주행속도가 높은 경우 커브길에서는 자동차가 주행속도의 관성에 의해 중앙선을 침범하거나, 언덕측으로 꺽여져 중·대형 사고를 유발할 염려가 많게된다. 이는 운전자가 자동차의 속도표시는 계기판을 통하여 인식하게 되나, 핸들 꺽임은 시각을 통하여 관측할 수 없으므로 직감에 의한 커브길 운전을 할 수 밖에 없기 때문이다. 그렇기 때문에, 주행속도 표시판이 도로상에 없는 시골길 특히 커브길에서는 상기와 같은 부주의에 의한 사고가 끊이지 않는 문제점이 지적되고 있다.In other words, despite the large angle of the steering wheel, when the vehicle driving speed is high, there is a high possibility that the vehicle may invade the center line due to the inertia of the driving speed or bend to the hillside to cause a heavy accident. This is because the driver recognizes the speed display of the vehicle through the instrument panel, but since the steering wheel can not be observed through vision, the driver has to drive the curve road by intuition. For this reason, it is pointed out that inadvertent accidents such as the above-mentioned carelessness do not stop on country roads, especially curve roads, in which the speed display plate is not on the road.
[고안이 해결하고자 하는 과제][Problem to Solve]
본 고안은 차량의 주행속도 표시지침과 핸들조향 각도지침을 계기판에 병행 설치하여 주행속도 표시판이 없는 시골길 운전시나, 커브길 운전시 조향핸들 각도와 자동차 진행속도가 맞지 않을 때에는 경고음을 울리도록 하여 안전사고를 예방하도록 하는 것이다.The present invention installs the vehicle's driving speed indicator and steering wheel steering angle guide on the instrument panel so that a warning sound sounds when the steering wheel angle does not match the driving speed when driving on a country road without a driving speed display or when driving on a curve. It is to prevent safety accidents.
[과제를 해결하기 위한 수단][Means for solving the problem]
핸들축에 설치된 기어와, 상기 핸들축의 기어와 맞물리도록한 볼륨기어에 핸들포지션 센서를 설치하고, 상기 핸들포지션 센서의 신호 입력을 오페앰프에 입력하며, 스피드 센서의 신호 입력을 F/V변환기에 입력케 하되, 상기 오페엠프와 F/V변환기 각각의 출력을 입력하여 대수관계를 이루며 증폭케 하는 곱셈IC와, 상기 곱셈IC로부터의 출력신호를 완충 증폭케하는 버퍼앰프와, 상기 버퍼앰프로부터 출력되는 신호에 의해 핸들회전 각도와 차량의 속도를 병행하여 표시케하는 계기판으로 이루어져 있다.A handle position sensor is installed on the gear installed in the handle shaft and the volume gear which meshes with the gear on the handle shaft, inputs the signal input of the handle position sensor to the op amp, and inputs the signal of the speed sensor to the F / V converter. A multiplier IC for inputting the outputs of the op amp and the F / V converter to amplify in an algebraic relationship, a buffer amplifier for buffering and amplifying the output signal from the multiplier IC, and an output from the buffer amplifier. It consists of an instrument panel that displays the steering wheel rotation angle and the speed of the vehicle in parallel by the signal.

제1도는 본 고안을 설명하기 위한 핸들 및 볼륨기어의 결합상태를 나타낸 것으로, 핸들축(1A)에 설치된 기어(1)에 볼륨기어(2)를 맞물리도록 하고, 핸들(3)의 주축(3A)을 회전시킴에 따라 상기 기어(1)가 회전되어 볼륨기어(2)를 회전시키도록 하되, 상기 볼륨기어(2)에 핸들포지션 센서(2A)를 설치하며 핸들포지션 센서(2A)의 감지에 따라 -5V-+5V범위로 감지하여 오페앰프(OP)에 입력되도록 구성한다.1 is a view illustrating a coupling state of a handle and a volume gear for explaining the present invention. The volume gear 2 is engaged with a gear 1 installed on the handle shaft 1A, and the main shaft 3A of the handle 3 is illustrated. ) Rotates the gear 1 to rotate the volume gear 2, but installs a handle position sensor 2A in the volume gear 2 and detects the handle position sensor 2A. Therefore, it is configured to detect the range of -5V- + 5V and input it to the operational amplifier (OP).
또한 스피드 센서측으로부터 입력되는 감지신호는 F/V변환기(4)에 입력되어 전압으로 변환시킨다.In addition, the detection signal input from the speed sensor side is input to the F / V converter 4 to convert to a voltage.
상기 오페앰프(OP)의 출력단 신호와 F/V변환기(4)의 출력단 신호는 곱셈IC(5)에 입력되어 대수관계를 이루면서 증폭케하고, 버퍼(6)에 의해 완충·증폭되어 계기판(7)에 핸들 회전각도지침(8)과 차량속도지침(9)이 병행하여 표시되도록 되어있다.The output terminal signal of the operational amplifier OP and the output terminal signal of the F / V converter 4 are input to the multiplication IC 5 to amplify in an algebraic relationship, buffered and amplified by the buffer 6, and the instrument panel 7 ), The steering wheel rotation angle guide 8 and the vehicle speed guide 9 are displayed in parallel.

한편, 본 고안은 조향각도별 허용속도표시를 미리 정하여 허용속도보다 핸들(3) 각도가 초과하면 경고음이 울리도록 할 수도 있는데, 이는 핸들포지션 센서(2A)로부터의 출력신호와 F/V변환기(4)의 출력신호를 비교기(도시생략)에 입력시켜 비교케하되, 허용속도보다 핸들각도가 초과하여 안전범위를 넘으면 비교기 출력단에 설치되는 경고음 발생장치(도시생략)에 의해 경고음이 발생하도록 구성할 수 있다. 상기에 있어서 허용범위는 차량종류에 따라 달리 할 수 있다.Meanwhile, the present invention may predetermine the allowable speed display for each steering angle, so that a warning sound sounds when the handle 3 angle exceeds the allowable speed, which is an output signal from the handle position sensor 2A and an F / V converter ( 4) The output signal of 4) is input to the comparator (not shown) for comparison, but if the handle angle exceeds the allowable speed and exceeds the safe range, a warning sound is generated by the warning sound generator (not shown) installed at the output of the comparator. Can be. In the above, the allowable range may vary depending on the type of vehicle.
[효과][effect]
이와같은 본 고안은 자동차의 주행속도와 핸들의 각도를 계기판을 통하여 운전자에게 표시하여 주게 하므로써 핸들의 각도에 따라 자동차의 주행속도를 조절케 할 수 있으므로, 주행속도 표시가 없는 시골길 운전이나, 커브길 운전시 안전사고를 미연에 방지할 수 있고, 특히, 핸들 조향 각도별 허용 스피드에 의해 안전범위 초과시 경고음을 울리도록 하여 주행속도를 운전자 스스로 조절케 하므로써 안전사고를 배제하도록 하는 특징이 있다.The present invention can control the driving speed of the vehicle according to the angle of the steering wheel by displaying the driving speed of the vehicle and the angle of the steering wheel to the driver through the instrument panel. Safety accidents can be prevented in advance while driving on the road, and in particular, a warning sound is generated when the safety range is exceeded by the allowable speed for each steering angle, so that the driving speed can be adjusted by the driver to exclude the safety accident.
