Description

【0001】
【発明の属する技術分野】
本発明は、霧の発生により視界が悪くなった道路を走行している車輌を安全に誘導するためのシステムに関する。
【0002】
【従来の技術】
道路の夜間照明は、視界の悪い夜間に、道路の危険な箇所を照明して車輌を安全に誘導する。この夜間照明は日没になる略定時刻に点灯を開始し、明るくなる略定時刻に消灯する。また照明の明るさも変える必要がない。
【0003】
霧が発生すると昼間でも視界が悪くなり、車輌を走行させることが困難になる。この際、夜間照明と同様に、道路の危険な箇所を照明することにより車輌を安全に誘導する事が考えられる。しかしながら霧は定時刻に発生し、定時刻に消失するものではない。即ち霧の発生により視界が悪くなった道路を走行している車輌を安全に誘導するためには、予知できない霧の発生開始時に点灯を開始し、予知できない霧の消失時に消灯できる事が必要である。また霧の程度により照明の明るさも変わる事が好ましい。
【0004】
霧発生時の車輌誘導は、夜間照明に比べて上記の如くに複雑である。従って照明による霧発生時の車輌誘導システムは広く実施されるには至っていない。
【0005】
【発明が解決しようとする課題】
本発明は、霧の発生により視界が悪くなった道路を走行している車輌を、照明により、安全且つ簡易に誘導する新たな方法を提供するものである。即ち、予知できない霧の発生開始時に点灯を開始し、予知できない霧の消失時に消灯する事が可能であり、また霧の中でも見易い色相の照明であり、また霧の程度により照明の明るさも変える事が可能な、霧発生時の車輌誘導システムの提供を課題としている。
【0006】
【課題を解決するための手段】
図1は本発明の車輌誘導システムを有する道路の説明図である。本発明では霧の発生程度を定量的に検知するための視程計11を用いる。本発明の視程計はレーザビームを投光部11−1から近距離に設けた、あるいは遠方に設けた受光部11−2に照射する。霧が発生していない場合はレーザビームの透過率は大きく反射率は小さい。一方濃霧の場合はレーザビームは霧により通過が妨げられて透過率は小さくなり反射率は大きくなる。本発明では視程計11によりレーザビームの透過率又は反射率を測定し、この測定結果に基づき、後述するハロゲンランプユニット12−2やセンターライン7の誘導ユニット1−1、1−2や走行車線区分13の誘導ユニット1−1,1−2の発光強さを、走行している運転者が見易い強さに設定し、車輌を安全に誘導する。視程計の設置基数は特定するものではないが、霧の発生状況が略等しい道路の領域毎に一基宛設けることが好ましい。
【0007】
本発明では走路の路肩近くに視線誘導灯12を配する。視線誘導灯としては走路に沿って間隔を設けて多数本設置したポール12−1の頂部にハロゲンランプユニット12−2が発光するものを用いる。濃霧の場合は、白色光よりもハロゲンランプの光の方が運転者にとって目視が容易である。
【0008】
本発明ではまた道路のセンターライン7の路面に間隔を設けて配したセンターライン誘導灯を用いる。本発明では道路の左側後方に光を発することにより左側の車線を走行する車輌の運転者に発光を見せる左側誘導ユニット1−1と、道路の右側後方に光を発することにより右側の車線を走行する車輌の運転者に発光を見せる右側誘導ユニット1−2を用い、左側誘導ユニット1−1と右側誘導ユニット1−2を一個宛、交互に道路のセンターライン7の路面に間隔を設けて配して、センターライン誘導灯を形成する。
【0009】
本発明では更に制御装置10を設ける。霧は予期しない時に急に発生し、また予期しない時に急に消失する。またこの発生と消失は頻繁に繰り返し発生する。視線誘導灯やセンターライン誘導灯は霧がない場合は点灯する必要はない。霧がない場合にも常時点灯すると、電力の消耗が大きい。一方霧が発生した際には視線誘導灯やセンターライン誘導灯は十分に点灯している事が重要である。
【0010】
本発明では視程計11によりレーザビームの透過率又は反射率を測定し、霧の発生の有無及び霧の程度を常時測定把握する。この測定結果は制御装置10に入力される。制御装置10は視程計11からの入力に基づき視線誘導灯のハロゲンランプユニット12−2やセンターラインの誘導ユニット1−1,1−2を、霧が発生した場合は点灯し、霧が濃い場合には更に運転者が見易い発光強さに発光を増大させ、霧が消失した場合にはこれ等を消灯するように制御する。
【0011】
本発明では、図1の走行車線区分ライン13にも誘導ユニットを設けることができる。即ち左側走路8の走行車線区分ライン13に沿って路面に間隔を設けて左側誘導ユニット1−1を配し左車線区分ライン誘導灯を形成する。この際、左走路8の走行車線区分ライン13の位置は、左走路8を走行する運転者に視認できれば十分である。右側走路9の走行車線区分ライン13に沿って、同様に右側誘導ユニット1−2を配して右走路9にも右車線区分ライン誘導灯を形成する。
【0012】
本発明の制御装置10はまた、左車線区分ライン誘導灯、右車線区分ライン誘導灯を霧が発生した場合は点灯し、霧が濃い場合には更に運転者が見易い発光強さに発光を増大させ、霧が消失した場合には消灯するように制御する。
【0013】
図2は本発明のセンターライン誘導灯のユニットの模式説明図である。本発明でセンターライン誘導灯の左側誘導ユニット1−1、右側誘導ユニット1−2は内部に光源2を配し、上面には上表面4が走路と同じ平面になる透明体6を配した上面以外は地中に埋める函体3とすることができる。光源2としては電球、発光ダイオード等を用いることができる。また透明体6としてはポリカーボネイト等を用いることができる。本発明で例えば左側誘導ユニット1−1は左の車線の運転者に見せるように左側後方に光を出すが、透明体の上表面から出る最強の光が車輌を走行させている運転者の目に入り易いように設定する。
【0014】
本発明では図1の例えば左側のユニット1−1は、左側走路の後方10mでの高さが1.2〜1.9mの方向に最強発光強さを出す左側ユニットとする。車輌により異なるが、本発明者等の知見によると、走行中の車輌の運転者の目の高さは、地上1.2〜1.9mである。また10m先の道路の位置が予め把握できると車輌の安全走行が可能である。従って左側後方10mでの高さが1.2〜1.9mの方向に最強の発光強さを出す左側誘導ユニットを用いると、左側誘導ユニットから10m左側後方を走行中の車輌の運転者は、左側ユニットの存在を容易に目視することができ、安全な走行が可能となる。
【0015】
図2で透明体6の上表面4は走路(GL)と同じ平面にある。またこの透明体6はその裏面5が上表面4に対し走路の前方から35〜45°下向きに傾斜した、走路の前方側が薄く走路の後方側が厚い形状の、ポリカーボネイト製の透明プリズムとする事が好ましい。尚光源2は透明プリズム6の傾斜裏面5に垂直方向の光を発する光源である。透明プリズムがポリカーボネイト製の場合は、ポリカーボネイトの光の屈折率は約1.6であるため、この透明プリズムを用いると光源2からの光は透明プリズムに入った後で透明プリズムの上表面4から走路の表面に対して約6°の仰角で空中に出る。走路の上表面4から約6°の仰角で出た光は、このユニットの10m後方の高さが1.2〜1.9mの方向に最強強さの光を出すことになる。
【0016】
本発明のセンターライン誘導灯が出す光は、緑色又は青色であることが好ましい。本発明者等の知見では、緑色又は青色は、霧の中では白色よりも視認し易い。また視線誘導灯の黄色のハロゲンランプとは色相が異なるために混同する事がない。
【0017】
図3(A)は、図2の誘導ユニット1が3基、透明プリズム6−1,6−2,6−3を連結して1個の透明プリズムに一体化した誘導ユニットの例である。図2では光源が1個であるため運転者は誘導ユニットを見過ごすこともあるが、図3(A)では3個の光源2−1,2−2,2−3を有し目立っているために、運転者は見過ごすことがない。図3(B)は3個の透明プリズム6−1,6−2,6−3を連結して1個の透明プリズムに一体化する際、一体化した透明プリズムを丈夫にするために、機能上支障がない尖った部分を減らした例で、図3(C)は更に丈夫にするために機能上支障がない尖った部分を更に減らした例である。尚図3(A)、図3(B)、図3(C)は作用効果を奏する部分の形状は同じであるため、同じ作用効果を奏する。
【0018】
即ち図3の誘導ユニット(A)、(B)、(C)は、その透明プリズム6が上面4が一の平面で下面には上面4に対して走路の前方から35〜45°下向きに走路の前方側が薄く走路の後方側が厚く傾斜した傾斜裏面5−1,5−2,5−3が上面4から同じ距離下方に配された形状の透明プリズムであり、各傾斜裏面5−1,5−2,5−3のそれぞれには、傾斜裏面5−1,5−2,5−3に対して垂直方向に光を発する光源がそれぞれ配された誘導ユニットである。
【0019】
【発明の効果】
本発明の車輌誘導システムは、車輌を誘導するための照明灯を霧の発生、消滅に合わせて自動的に点灯し消灯する事が可能である。また本発明の照明灯は霧の中では白色光よりも視認し易い色相であり、且つ車輌の運転者が見易い方向に光を照射している。従って本発明を用いると、霧の発生により視界が悪くなった道路を走行している車輌を、安全に且つ簡易に誘導することが可能になる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a system for safely guiding a vehicle traveling on a road whose visibility is deteriorated due to generation of fog.
[0002]
[Prior art]
Road night lighting illuminates dangerous parts of the road and guides the vehicle safely at night when visibility is poor. The night lighting starts to be turned on at a substantially fixed time when sunset occurs, and is turned off at a substantially fixed time when it becomes bright. Also, there is no need to change the brightness of the lighting.
[0003]
When fog is generated, visibility becomes poor even in the daytime, and it becomes difficult to drive the vehicle. At this time, it is conceivable to safely guide the vehicle by illuminating a dangerous part of the road as in the case of night illumination. However, fog occurs at a fixed time and does not disappear at a fixed time. In other words, in order to safely guide a vehicle traveling on a road with poor visibility due to fog, it is necessary to start turning on when unforeseeable fog starts and turn off when unforeseeable fog disappears. is there. Further, it is preferable that the brightness of the illumination also changes depending on the degree of fog.
[0004]
Vehicle guidance when fog occurs is more complicated than nighttime illumination as described above. Therefore, the vehicle guidance system when fog is generated by lighting has not been widely implemented.
[0005]
[Problems to be solved by the invention]
The present invention provides a new method for safely and easily guiding a vehicle traveling on a road whose visibility is deteriorated due to the generation of fog by lighting. In other words, it can be turned on when unforeseeable fog starts to be generated, and can be turned off when unforeseeable fog disappears. It is an object of the present invention to provide a vehicle guidance system that can be used when fog occurs.
[0006]
[Means for Solving the Problems]
FIG. 1 is an explanatory view of a road having the vehicle guidance system of the present invention. In the present invention, a visibility meter 11 for quantitatively detecting the degree of fog generation is used. The visibility meter according to the present invention irradiates a laser beam to a light receiving unit 11-2 provided at a short distance or far from the light projecting unit 11-1. When no fog is generated, the transmittance of the laser beam is large and the reflectance is small. On the other hand, in the case of dense fog, the passage of the laser beam is hindered by the fog, so that the transmittance is reduced and the reflectance is increased. In the present invention, the transmittance or reflectance of the laser beam is measured by the visibility meter 11, and based on the measurement result, the halogen lamp unit 12-2, the guide units 1-1 and 1-2 of the center line 7, and the traveling lane are described later. The luminous intensity of the guidance units 1-1 and 1-2 of the section 13 is set to a level that is easy for the traveling driver to see, and the vehicle is guided safely. Although the number of installation units of the visibility meter is not specified, it is preferable that one installation device be provided for each area of the road where fog occurrence is substantially equal.
[0007]
In the present invention, the line-of-sight guidance light 12 is arranged near the shoulder of the runway. As the line-of-sight guide lamp, a lamp that emits light from the halogen lamp unit 12-2 at the top of a large number of poles 12-1 that are provided at intervals along the runway is used. In the case of dense fog, the light of the halogen lamp is easier for the driver to see than the white light.
[0008]
In the present invention, a center line guide light provided at intervals on the road surface of the center line 7 of the road is used. According to the present invention, the left guiding unit 1-1 emits light to the left rear of the road to emit light to a driver of a vehicle traveling in the left lane, and the vehicle travels in the right lane by emitting light to the right rear of the road. The right guidance unit 1-2 which emits light to the driver of the vehicle to be driven is used, and the left guidance unit 1-1 and the right guidance unit 1-2 are addressed one by one and are alternately arranged on the road surface of the center line 7 of the road. Thus, a center line guide light is formed.
[0009]
In the present invention, a control device 10 is further provided. The fog suddenly occurs at unexpected times and disappears unexpectedly. This occurrence and disappearance frequently occur repeatedly. It is not necessary to turn on the line of sight or center line lights when there is no fog. Even if there is no fog, if it is always lit, power consumption is large. On the other hand, when fog occurs, it is important that the gaze guide light and the center line guide light are sufficiently lit.
[0010]
In the present invention, the transmittance or reflectance of the laser beam is measured by the visibility meter 11, and the presence or absence of fog and the degree of fog are constantly measured and grasped. This measurement result is input to the control device 10. The control device 10 turns on the halogen lamp unit 12-2 of the line-of-sight guidance light and the guidance units 1-1 and 1-2 of the center line based on the input from the visibility meter 11, when fog is generated, and when the fog is thick. In this case, the light emission is further increased to a light emission intensity that is easy for the driver to see, and when the fog has disappeared, these are turned off.
[0011]
In the present invention, the guidance unit can be provided also in the traveling lane division line 13 in FIG. That is, the left guidance unit 1-1 is arranged at intervals on the road surface along the traveling lane division line 13 of the left lane 8 to form a left lane division line guidance light. At this time, it is sufficient that the position of the traveling lane division line 13 on the left lane 8 can be visually recognized by a driver traveling on the left lane 8. Along the traveling lane division line 13 of the right lane 9, a right lane guidance unit 1-2 is similarly arranged, and a right lane lane marking line is formed on the right lane 9 as well.
[0012]
The control device 10 of the present invention also turns on the left lane division line guidance light and the right lane division line guidance light when fog occurs, and increases the light emission to a light emission intensity that is more easily seen by the driver when the fog is dense. When the fog disappears, the light is turned off.
[0013]
FIG. 2 is a schematic explanatory view of a unit of the center line guide light of the present invention. In the present invention, the left guide unit 1-1 and the right guide unit 1-2 of the center line guide light are provided with the light source 2 inside, and the upper surface is provided with the transparent body 6 on the upper surface of which the upper surface 4 is the same plane as the track. Other than the above, a box 3 buried in the ground can be used. As the light source 2, a light bulb, a light emitting diode, or the like can be used. Further, as the transparent body 6, polycarbonate or the like can be used. In the present invention, for example, the left guidance unit 1-1 emits light rearward on the left side so as to be seen by the driver in the left lane, but the strongest light emitted from the upper surface of the transparent body is the eye of the driver running the vehicle. Set to make it easy to enter.
[0014]
In the present invention, for example, the left unit 1-1 in FIG. 1 is a left unit that emits the strongest luminous intensity in a direction in which the height at 10 m behind the left running road is 1.2 to 1.9 m. According to the knowledge of the present inventors, the height of the driver's eyes of a running vehicle is 1.2 to 1.9 m from the ground, though it depends on the vehicle. Also, if the position of the road 10 m ahead can be grasped in advance, the vehicle can run safely. Therefore, using a left guidance unit that emits the strongest luminous intensity in the direction of 1.2 to 1.9 m at the left rear 10 m, the driver of the vehicle traveling 10 m left rear from the left guidance unit, The presence of the left side unit can be easily visually checked, and safe driving can be performed.
[0015]
In FIG. 2, the upper surface 4 of the transparent body 6 is on the same plane as the track (GL). The transparent body 6 may be a polycarbonate transparent prism whose rear surface 5 is inclined downward by 35 to 45 ° from the front of the runway with respect to the upper surface 4, the front side of the runway is thin and the rear side of the runway is thick. preferable. The light source 2 is a light source that emits light in the vertical direction on the inclined back surface 5 of the transparent prism 6. When the transparent prism is made of polycarbonate, since the refractive index of light of polycarbonate is about 1.6, when this transparent prism is used, light from the light source 2 enters the transparent prism and then enters the transparent prism from the upper surface 4 of the transparent prism. Exits the air at an elevation of about 6 ° relative to the surface of the runway. The light emitted from the upper surface 4 of the runway at an elevation angle of about 6 ° will emit the strongest light in a direction in which the height 10 m behind the unit is 1.2 to 1.9 m.
[0016]
The light emitted by the center line guide light of the present invention is preferably green or blue. According to the findings of the present inventors, green or blue is more visible in fog than white. Further, since the hue is different from that of the yellow halogen lamp of the line-of-sight guidance lamp, there is no confusion.
[0017]
FIG. 3A shows an example of a guide unit in which three guide units 1 of FIG. 2 are connected to one transparent prism by connecting the transparent prisms 6-1, 6-2, and 6-3. In FIG. 2, the driver may overlook the guidance unit because there is only one light source. However, in FIG. 3A, the driver has three light sources 2-1, 2-2, and 2-3 and is noticeable. In addition, the driver does not overlook. FIG. 3B shows a function for connecting the three transparent prisms 6-1, 6-2, 6-3 and integrating them into one transparent prism in order to make the integrated transparent prism strong. FIG. 3 (C) shows an example in which the sharp portions having no functional hindrance are further reduced in order to further increase the strength. 3 (A), 3 (B), and 3 (C) have the same function and effect because the portions having the function and effect are the same in shape.
[0018]
That is, in the guiding units (A), (B), and (C) of FIG. 3, the transparent prism 6 has the upper surface 4 on one plane and the lower surface on the lower surface 35 to 45.degree. Are transparent prisms having a shape in which the front side is thinner and the rear side of the track is thicker and the rear side is inclined at the same distance from the upper surface 4. Each of −2 and 5-3 is a guiding unit in which a light source that emits light in a direction perpendicular to the inclined back surfaces 5-1, 5-2 and 5-3 is arranged.
[0019]
【The invention's effect】
The vehicle guidance system of the present invention can automatically turn on and off the illuminating lamp for guiding the vehicle in accordance with the occurrence and disappearance of fog. Further, the illumination lamp of the present invention has a hue that is more easily recognized in fog than white light, and emits light in a direction that is easy for a driver of the vehicle to see. Therefore, when the present invention is used, it is possible to safely and easily guide a vehicle traveling on a road whose visibility is deteriorated due to generation of fog.
