　本発明は、自動運転車両に搭載する車両用灯具に関する。 The present invention relates to a vehicle lamp mounted on an autonomous vehicle.
　現在、自動車の自動運転技術の研究が各国で盛んに行われており、自動運転モードで車両が公道を走行することができるための法整備が各国で検討されている。自動運転には、レベル０～５が定義されており、一般的には、レベル３以上が自動運転とされている。レベル３は、条件付き自動運転と呼ばれ、特定の場所でシステムが全てを操作し、緊急時はドライバーが操作を行うものである。レベル４は、高度自動運転と呼ばれ、システムが高速道路など特定の場所に限り交通状況を認知して、運転に関わる全ての操作を行うものである。レベル５は、完全自動運転と呼ばれ、システムが場所の制限なく交通状況を認知して、運転に関わる全ての操作を行うものである。 Currently, research on automatic driving technology for automobiles is actively carried out in each country, and legislation is being studied in each country to enable vehicles to travel on public roads in automatic driving mode. Levels 0 to 5 are defined for automatic operation, and generally level 3 or higher is automatic operation. Level 3 is called conditional automatic driving, in which the system operates everything at a specific location and the driver operates in an emergency. Level 4 is called highly automated driving, and the system recognizes traffic conditions only in a specific place such as an expressway and performs all operations related to driving. Level 5 is called fully automatic driving, in which the system recognizes traffic conditions without restrictions on location and performs all driving-related operations.

The vehicular lamp 10 also includes a millimeter wave radar 26, a camera 24, and a LiDAR 28 as sensor devices. Further, the vehicle lamp 10 includes a control device 42 connected to the lamp unit and the sensor device. The control device 42 may be arranged inside the lamp body 12 of the vehicular lamp 10 or may be arranged outside the lamp body 12.
　図５に示すように、制御装置４２は、車両１００が備える自動運転制御装置４４に接続されてよい。制御装置４２は、車両１００が自動運転中であるか否かの情報を自動運転制御装置４４から取得し、自動運転を行っている間は自動運転マーカ用灯具ユニット２０をターコイズ色で発光させる。 As shown in FIG. 5, the control device 42 may be connected to an automatic driving control device 44 included in the vehicle 100. The control device 42 acquires information on whether or not the vehicle 100 is in automatic driving from the automatic driving control device 44, and causes the automatic driving marker lamp unit 20 to emit turquoise color while performing automatic driving.
　カメラ２４は、車両周囲を撮像し、撮像した画像を制御装置４２に送る。制御装置４２は、カメラ２４により撮像された画像から車両周囲の人の画像認識を行い、予め登録された乗員が車両周囲にいることを検知する。画像を用いて検知しているので、カメラ２４から見て乗員の存在する方向を検知することができる。検知精度を高めるために、カメラ２４に加えてミリ波レーダ２６やＬｉＤＡＲ２８を利用してもよい。 The camera 24 captures an image around the vehicle and sends the captured image to the control device 42. The control device 42 performs image recognition of people around the vehicle from the image captured by the camera 24, and detects that a pre-registered occupant is around the vehicle. Since the image is used for detection, the direction in which the occupant is present can be detected as viewed from the camera 24. In addition to the camera 24, the millimeter wave radar 26 or the LiDAR 28 may be used to improve the detection accuracy.
　図６は、路面描画灯具ユニット２２による路面描画の一例を示す。図６は、乗員６０が駐車場に停めてある車両１００に向かっている状況を示す。制御装置４２は、車両１００の周囲に乗員６０が検知されたとき、路面描画灯具ユニット２２を制御して、検知された乗員６０の存在する方向に向かって車両周囲の路面にシーケンシャルパターン６２を描画する。シーケンシャルパターンとは、連鎖的に点灯する照射パターンであり、例えば、乗員６０の近傍の位置から車両１００に向かって連続的に路面に描画されたパターンである。このようなシーケンシャルパターンを路面描画することにより、車両に１００に戻ってきた乗員６０に「おもてなし」の演出をすることができる。本第１実施形態に係る車両用灯具１０によれば、このようにして、乗員との間でコミュニケーションをとることができる。 FIG. 6 shows an example of road surface drawing by the road surface drawing lamp unit 22. FIG. 6 shows a situation in which the occupant 60 is heading toward the vehicle 100 parked in the parking lot. When the occupant 60 is detected around the vehicle 100, the control device 42 controls the road surface drawing lamp unit 22 to draw a sequential pattern 62 on the road surface around the vehicle in the direction in which the detected occupant 60 exists. To do. The sequential pattern is an irradiation pattern that lights up in a chain, and is, for example, a pattern continuously drawn on the road surface from a position near the occupant 60 toward the vehicle 100. By drawing such a sequential pattern on the road surface, the "hospitality" can be provided to the occupant 60 who has returned to the vehicle 100. According to the vehicular lamp 10 according to the first exemplary embodiment, it is possible to communicate with the occupant in this manner.
　さらに制御装置４２は、路面描画灯具ユニット２２とは異なる別の灯具ユニット、例えば自動運転マーカ用灯具ユニット２０を路面描画灯具ユニット２２と連動させて、シーケンシャルに発光させてもよい。路面描画灯具ユニット２２は、ターコイズ色で発光する複数の発光ユニット３４を有するので、斬新なシーケンシャル発光が可能であり、乗員６０に対してより印象的な「おもてなし」の演出をすることができる。「自動運転マーカ用灯具ユニット２０と路面描画灯具ユニット２２とが連動する」とは、例えば、路面描画灯具ユニット２２によるシーケンシャルパターンの路面描画が終わった後に自動運転マーカ用灯具ユニット２０のシーケンシャル発光が開始するものであってもよい。あるいは、路面描画灯具ユニット２２によるシーケンシャルパターンの描画の最中に自動運転マーカ用灯具ユニット２０のシーケンシャル発光が行われるものであってもよい。 Further, the control device 42 may cause another lamp unit different from the road surface drawing lamp unit 22, for example, the automatic driving marker lamp unit 20 to interlock with the road surface drawing lamp unit 22 to sequentially emit light. Since the road surface drawing lamp unit 22 has the plurality of light emitting units 34 that emit light in turquoise color, novel sequential light emission is possible, and a more impressive "hospitality" effect can be provided to the occupant 60. “The automatic driving marker lamp unit 20 and the road surface drawing lamp unit 22 are interlocked with each other” means that, for example, the sequential light emission of the automatic driving marker lamp unit 20 is finished after the road surface drawing lamp unit 22 finishes drawing the road surface in a sequential pattern. It may be the one that starts. Alternatively, the sequential driving of the automatic driving marker lamp unit 20 may be performed during the drawing of the sequential pattern by the road surface drawing lamp unit 22.
　路面描画灯具ユニット２２に加えてまたは代えて、前照灯ユニット１６やターンシグナルランプ１８を路面描画灯具ユニット２２と連動させて、シーケンシャルに発光させてもよい。 In addition to or instead of the road surface drawing lamp unit 22, the headlight unit 16 and the turn signal lamp 18 may be linked with the road surface drawing lamp unit 22 to sequentially emit light.
　図７は、路面描画灯具ユニット２２による路面描画の別の例を示す。図７は、車両１００の周囲に乗員が存在していない状況を示す。制御装置４２は、車両１００の周囲に乗員６０が検知されないとき、路面描画灯具ユニット２２を制御して、車両周囲の照射可能領域にシーケンシャルパターン６４を描画する。このようなシーケンシャルパターンを路面描画することにより、車両周囲の人に対して「おもてなし」の演出をすることができる。 FIG. 7 shows another example of road surface drawing by the road surface drawing lamp unit 22. FIG. 7 shows a situation where no occupant exists around vehicle 100. When the occupant 60 is not detected around the vehicle 100, the control device 42 controls the road surface drawing lamp unit 22 to draw the sequential pattern 64 in the irradiable area around the vehicle. By drawing such a sequential pattern on the road surface, "hospitality" can be provided to people around the vehicle.
　図８は、アウターレンズ１４の一部を示す概略図である。アウターレンズ１４は、自動運転マーカ用灯具ユニット２０用のアウターレンズ１４ａと、前照灯ユニット１６、ターンシグナルランプ１８および路面描画灯具ユニット２２用のアウターレンズ１４ｂと、を備える。本第１実施形態では、これらのアウターレンズ１４ａ、１４ｂは、フロントパネル８０およびボンネット８２と一体的に樹脂部材で形成されている。このような樹脂部材による一体成形品とすることで、車両１００の軽量化を図ることができる。 FIG. 8 is a schematic view showing a part of the outer lens 14. The outer lens 14 includes an outer lens 14a for the automatic driving marker lamp unit 20 and an outer lens 14b for the headlamp unit 16, the turn signal lamp 18, and the road surface drawing lamp unit 22. In the first embodiment, the outer lenses 14a and 14b are integrally formed of a resin member with the front panel 80 and the hood 82. By integrally molding the resin member, the weight of the vehicle 100 can be reduced.
　図９は、アウターレンズ１４ａとボンネット８２の境界部分の概略図である。アウターレンズ１４ａ、１４ｂは透明であり、ボンネット８２やフロントパネル８０は着色される。したがって、アウターレンズ１４ａとボンネット８２の境界部分（図８のＣ部分）や、アウターレンズ１４ｂとフロントパネル８０の境界部分（図８のＤ部分）には、境界線（見切り線）が生じる。本第１実施形態においては、図８に示すように、境界部分の着色にグラデーションを設けることにより、境界線が目立たないようにしている。これにより、車両用灯具１０と車両１００のボディとの一体感が高まった斬新な意匠を実現できる。 FIG. 9 is a schematic view of a boundary portion between the outer lens 14a and the hood 82. The outer lenses 14a and 14b are transparent, and the hood 82 and the front panel 80 are colored. Therefore, a boundary line (parting line) is generated at the boundary portion between the outer lens 14a and the hood 82 (C portion in FIG. 8) and the boundary portion between the outer lens 14b and the front panel 80 (D portion in FIG. 8). In the first embodiment, as shown in FIG. 8, the boundary line is made inconspicuous by providing a gradation for coloring the boundary portion. Accordingly, it is possible to realize a novel design in which the sense of unity between the vehicular lamp 10 and the body of the vehicle 100 is enhanced.
　図１に戻るが、本第１実施形態に係る車両１００においては、ボディ１０２とサイドウィンドウ１０４との境界部分に、線状の導光体１０６を配置している。導光体１０６は、ターコイズ色で発光するように構成される。このような導光体１０６を配置することにより、車両１００の側方に、車両１００が自動運転中であることを知らせることができ、安全性を向上できる。 Returning to FIG. 1, in the vehicle 100 according to the first embodiment, the linear light guide body 106 is arranged at the boundary between the body 102 and the side window 104. The light guide 106 is configured to emit a turquoise color. By disposing such a light guide body 106, it is possible to inform the side of the vehicle 100 that the vehicle 100 is in automatic driving, and it is possible to improve safety.
［第２実施形態］
　自動運転車には、周囲に自車両が自動運転中であることを知らせるためのランプ（「自動運転用標識灯」と呼ばれる）を取り付ける必要があり、現在、規格作りが進んでいる。このような状況の下、本発明者は、自動運転中の表示だけではなく、乗員や車両周囲の人とコミュニケーションをとることができる車両用灯具を発明した。 [Second Embodiment]
It is necessary to attach a lamp (called an "autonomous driving sign lamp") around the self-driving vehicle to inform that the own vehicle is in the automatic driving state, and standardization is currently in progress. Under such circumstances, the inventor of the present invention invented a vehicular lamp that can communicate not only with a display during automatic driving but also with passengers and people around the vehicle.
　第２実施形態はこうした状況に鑑みてなされたものであり、その目的は、自動運転中の表示を行うとともに、車両周囲の人とコミュニケーションをとることができる車両用灯具を提供することにある。 The second embodiment has been made in view of such a situation, and an object thereof is to provide a vehicular lamp capable of displaying while the vehicle is driving automatically and communicating with people around the vehicle.
　図１０は、本発明の第２実施形態に係る車両用灯具１０１０を搭載した車両１１００の側面図である。図１１は、本発明の第２実施形態に係る車両用灯具１０１０を搭載した車両１１００の正面図である。 FIG. 10 is a side view of a vehicle 1100 equipped with a vehicle lamp 1010 according to the second embodiment of the present invention. FIG. 11 is a front view of a vehicle 1100 equipped with a vehicle lamp 1010 according to the second embodiment of the present invention.
　車両１１００は、レベル５の完全自動運転に対応した車両であり、運転席を備えていない。車両１１００は、車両の長さ方向（車幅方向に垂直な方向、以下適宜「車長方向」と呼ぶ）においてほぼシンメトリーであり、車長方向の両方に移動可能である。便宜上、車長方向の一方（図１０の左側）を正面側とし、車長方向の他方（図１０の右側）を背面側とする。車両１１００は、乗員が乗り降りする乗降部１１０２、タイヤ１１０４等を備える。 The vehicle 1100 is a vehicle that supports level 5 fully autonomous driving and does not have a driver's seat. Vehicle 1100 is substantially symmetrical in the length direction of the vehicle (direction perpendicular to the vehicle width direction, hereinafter appropriately referred to as “vehicle length direction”), and is movable in both vehicle length directions. For convenience, one side in the vehicle length direction (left side in FIG. 10) is the front side, and the other side in the vehicle length direction (right side in FIG. 10) is the back side. The vehicle 1100 includes a boarding/alighting section 1102, on which a passenger gets in and out, tires 1104, and the like.
　図１０に示すように、車両１１００の正面側には車両用灯具１０１０が配置され、背面側には車両用灯具１０１１が配置される。車両用灯具１０１０、１０１１の構成および機能は略同じであるので、以下の説明では正面側に配置される車両用灯具１０１０について説明する。 As shown in FIG. 10, a vehicle lamp 1010 is arranged on the front side of the vehicle 1100, and a vehicle lamp 1011 is arranged on the rear side. Since the vehicle lamps 1010 and 1011 have substantially the same configuration and function, the vehicle lamp 1010 arranged on the front side will be described below.
　図１２は、車両用灯具１０１０の一部を示す概略正面図である。図１３は、図１２に示す車両用灯具１０１０のＡ－Ａ概略断面図である。車両用灯具１０１０は、ランプボディ１０１２と、ランプボディ１０１２の灯具前方側に配置される透明なアウターレンズ１０１４とを備える。ランプボディ１０１２とアウターレンズ１０１４は灯室１０１６を形成している。 FIG. 12 is a schematic front view showing a part of the vehicle lamp 1010. FIG. 13 is a schematic cross-sectional view taken along the line AA of the vehicular lamp 1010 shown in FIG. The vehicular lamp 1010 includes a lamp body 1012 and a transparent outer lens 1014 arranged on the lamp body 1012 front side of the lamp. The lamp body 1012 and the outer lens 1014 form a lamp chamber 1016.
　灯室１０１６内には、複数の灯具ユニットが配置される。本第２実施形態に係る車両用灯具１０１０においては、正面視で略四角形状に灯具ユニットが配置されている。 A plurality of lamp units are arranged in the lamp room 1016. In the vehicular lamp 1010 according to the second exemplary embodiment, the lamp units are arranged in a substantially quadrangular shape in a front view.
　略水平方向に延びる四角形の上辺の位置には、自動運転（ＡＤ：Automated Driving）マーカ用灯具ユニット１０１８が配置される。自動運転マーカ用灯具ユニット１０１８は、車両が自動運転中であることを周囲に知らせるためのランプであり、車両が自動運転を行っている間にターコイズ色の光を常時発光する。 A lamp unit 1018 for an automated driving (AD) marker is arranged at the position of the upper side of a quadrangle extending in a substantially horizontal direction. The automatic driving marker lamp unit 1018 is a lamp for informing the surroundings that the vehicle is in automatic driving, and constantly emits turquoise light while the vehicle is in automatic driving.
　また、略水平方向に延びる四角形の下辺の位置には、自動運転（ＡＤ）シグナル用灯具ユニット１０２０が配置される。すなわち、自動運転シグナル用灯具ユニット１０２０は、自動運転マーカ用灯具ユニット１０１８から所定の距離をあけて配置される。これは、自動運転マーカ用灯具ユニット１０１８の発光状態と自動運転シグナル用灯具ユニット１０２０の発光状態の識別をしやすくするためである。自動運転シグナル用灯具ユニット１０２０は、自動運転車両が歩行者等に対し、道を譲る、発進を示唆する等のコミュニケーションをとるためのランプであり、車両周囲の情報に基づき発光パターンを可変できる。 Also, an automatic operation (AD) signal lamp unit 1020 is arranged at the position of the lower side of a rectangle extending in a substantially horizontal direction. That is, the automatic driving signal lamp unit 1020 is arranged at a predetermined distance from the automatic driving marker lamp unit 1018. This is to make it easier to distinguish the light emitting state of the automatic driving marker lamp unit 1018 from the light emitting state of the automatic driving signal lamp unit 1020. The self-driving signal lamp unit 1020 is a lamp for the self-driving vehicle to communicate with a pedestrian or the like such as giving way to the pedestrian or suggesting a start, and the light emission pattern can be changed based on information around the vehicle.
　自動運転マーカ用灯具ユニット１０１８および自動運転シグナル用灯具ユニット１０２０はそれぞれ、複数のターコイズ色で発光するＬＥＤ１０２２と、透明なインナーレンズ１０２４とを備え、ターコイズ色の光を照射する。あるいは、白色発光のＬＥＤと、ターコイズ色のインナーレンズを用いてターコイズ色の光を照射するように構成されてもよい。 Each of the automatic driving marker lamp unit 1018 and the automatic driving signal lamp unit 1020 includes an LED 1022 that emits a plurality of turquoise colors and a transparent inner lens 1024, and emits turquoise light. Alternatively, a white light emitting LED and a turquoise inner lens may be used to irradiate turquoise light.
　略垂直方向に延びる四角形の左辺および右辺の位置には、３つの照射光色可変灯具ユニット１０２６と、３つの自動運転シグナル用灯具ユニット１０２０とが垂直方向に交互に配置されている。それらの灯具ユニットの下方には、歩行者等を検出するためのミリ波レーダ１０２８と、ミリ波レーダ１０２８の正面を覆うように配置される導光体１０３０と、導光体１０３０内に光を供給する光源１０３２とが配置されている。このように、ミリ波レーダ１０２８の正面を導光体１０３０で覆い発光させることで、ミリ波レーダ１０２８の存在を隠し、見栄えを向上することができる。 Three irradiation light color variable lamp units 1026 and three automatic operation signal lamp units 1020 are alternately arranged in the vertical direction at positions on the left and right sides of a quadrangle extending in a substantially vertical direction. A millimeter wave radar 1028 for detecting a pedestrian or the like, a light guide body 1030 arranged so as to cover the front surface of the millimeter wave radar 1028, and light inside the light guide body 1030 are provided below the lamp units. A light source 1032 for supplying is arranged. In this manner, by covering the front surface of the millimeter wave radar 1028 with the light guide 1030 to emit light, the presence of the millimeter wave radar 1028 can be hidden and the appearance can be improved.
　照射光色可変灯具ユニット１０２６は、車両進行方向に照射すべき白色光と、車両進行方向と逆方向に照射すべき赤色光とのいずれかを照射可能に構成される。車両進行方向に照射すべき白色光とは、通常のヘッドランプに求められる法規を満たす色および強度の光である。また、車両進行方向と逆方向に照射すべき赤色光とは、通常のリヤランプに求められる法規を満たす色および強度の光である。このような照射光色可変灯具ユニット１０２６は、車両進行方向に応じて白色光と赤色光のいずれかを灯具前方に照射することができるので、周囲の状況に応じて進行方向が切り替わる完全自動運転車に適している。 The variable illumination light color lamp unit 1026 is configured to be capable of emitting either white light to be emitted in the traveling direction of the vehicle or red light to be emitted in the opposite direction to the traveling direction of the vehicle. The white light to be emitted in the traveling direction of the vehicle is light of a color and intensity that meets the regulations required for ordinary headlamps. Further, the red light to be emitted in the direction opposite to the traveling direction of the vehicle is light of a color and intensity that meets the regulations required for ordinary rear lamps. Such a variable illumination light color lamp unit 1026 can illuminate either the white light or the red light in front of the lamp according to the traveling direction of the vehicle, so that the traveling direction is switched depending on the surrounding conditions. Suitable for cars.
　図１２に示すように、略四角形状に配置された複数の灯具ユニットの内側には、ディスプレイ装置１０６０が配置されている。ディスプレイ装置１０６０には、車両１１００の状態情報が表示される。ディスプレイ装置１０６０は、薄型ディスプレイであれば特に限定されず、有機ＥＬディスプレイや液晶ディスプレイを好適に用いることができる。 As shown in FIG. 12, a display device 1060 is arranged inside a plurality of lamp units arranged in a substantially rectangular shape. The display device 1060 displays the state information of the vehicle 1100. The display device 1060 is not particularly limited as long as it is a thin display, and an organic EL display or a liquid crystal display can be preferably used.
　図１４は、本発明の第２実施形態に係る車両用灯具１０１０を説明するための機能ブロック図である。図１３に示すように、車両用灯具１０１０は、車両周囲の情報を検知するセンサ装置としてのミリ波レーダ１０２８と、自動運転マーカ用灯具ユニット１０１８と、自動運転シグナル用灯具ユニット１０２０と、ディスプレイ装置１０６０と、制御装置１０４０と、を備える。制御装置１０４０は、車両用灯具１０１０のランプボディ１０１２内に配置されてもよいし、ランプボディ１０１２の外に配置されてもよい。 FIG. 14 is a functional block diagram for explaining a vehicular lamp 1010 according to the second embodiment of the present invention. As shown in FIG. 13, a vehicle lamp 1010 includes a millimeter wave radar 1028 as a sensor device that detects information around the vehicle, an automatic driving marker lamp unit 1018, an automatic driving signal lamp unit 1020, and a display device. 1060 and a control device 1040. The control device 1040 may be arranged inside the lamp body 1012 of the vehicular lamp 1010, or may be arranged outside the lamp body 1012.
　ミリ波レーダ１０２８により検知された情報は、制御装置１０４０に送られる。制御装置１０４０は、ミリ波レーダ１０２８からの情報から人を検知する。 Information detected by the millimeter wave radar 1028 is sent to the control device 1040. The control device 1040 detects a person from the information from the millimeter wave radar 1028.
　図１４に示すように、制御装置１０４０は、車両１１００が備える自動運転制御装置１０４１に接続されてよい。制御装置１０４０は、車両１１００が自動運転中であるか否かの情報を自動運転制御装置１０４１から取得し、自動運転を行っている間は自動運転マーカ用灯具ユニット１０１８を常時発光させる。 As shown in FIG. 14, the control device 1040 may be connected to the automatic driving control device 1041 included in the vehicle 1100. The control device 1040 acquires information on whether or not the vehicle 1100 is in automatic driving from the automatic driving control device 1041 and causes the automatic driving marker lamp unit 1018 to constantly emit light during automatic driving.
　また、制御装置１０４０は、ミリ波レーダ１０２８により検知された車両周囲の情報に基づき、自動運転シグナル用灯具ユニット１０２０の発光パターンを制御する。例えば歩行者を検知して停止したとき、自動運転シグナル用灯具ユニット１０２０を例えば一方の端部から他方の端部に連続的に点灯させることにより、歩行者に道を譲る意志表示をする。本第２実施形態によれば、このようにして車両周囲の歩行者等との間でコミュニケーションをとることができる。 Further, the control device 1040 controls the light emission pattern of the automatic driving signal lamp unit 1020 based on the information around the vehicle detected by the millimeter wave radar 1028. For example, when a pedestrian is detected and stopped, the automatic driving signal lamp unit 1020 is continuously illuminated, for example, from one end to the other end, thereby indicating that the pedestrian is willing to give way. According to the second embodiment, it is possible to communicate with pedestrians and the like around the vehicle in this manner.
　また、制御装置１０４０は、ディスプレイ装置１０６０の表示を制御する。制御装置１０４０は、例えばテールランプやストップランプと連動して、これらのランプを補助するための表示をディスプレイ装置１０６０に行ってもよい。テールランプやストップランプの点消灯情報は、自動運転制御装置１０４１から取得してよい。例えば、ストップランプと連動してディスプレイ装置１０６０を赤く発光させることにより、歩行者や他の車両に対する注意喚起を高めることができる。 Further, the control device 1040 controls the display of the display device 1060. The control device 1040 may provide a display for assisting these lamps on the display device 1060 in cooperation with, for example, a tail lamp or a stop lamp. The on/off information of the tail lamp and the stop lamp may be acquired from the automatic driving control device 1041. For example, by causing the display device 1060 to emit red light in conjunction with the stop lamp, the pedestrian and other vehicles can be alerted.
　また、制御装置１０４０は、ミリ波レーダ１０２８により歩行者が所定距離以内に接近したことが検知された場合、ディスプレイ装置１０６０の発光強度を高めたり、発光色を変化させたりしてもよい。これにより、歩行者に対して車両が近づいていることを認識させることができる。 The control device 1040 may increase the light emission intensity of the display device 1060 or change the light emission color when the millimeter wave radar 1028 detects that a pedestrian approaches within a predetermined distance. This allows the pedestrian to recognize that the vehicle is approaching.
　また、制御装置１０４０は、ディスプレイ装置１０６０を単に発光させるだけでなく、車両の状態情報を歩行者や他の車両に提示するために、図形や文字をディスプレイ装置１０６０に表示されてもよい。例えば、文字やアイコンをディスプレイ装置１０６０に表示して、事故や工事情報、落下物情報、緊急避難情報等を他の車両や歩行者に提示することができる。 The control device 1040 may display graphics or characters on the display device 1060 in order to present the vehicle state information to pedestrians and other vehicles, in addition to simply causing the display device 1060 to emit light. For example, characters or icons can be displayed on the display device 1060 to present accident and construction information, falling object information, emergency evacuation information, etc. to other vehicles and pedestrians.
　以上説明したように、本第２実施形態に係る車両用灯具１０１０では、自動運転マーカ用灯具ユニット１０１８と自動運転シグナル用灯具ユニット１０２０を所定の距離をあけて上下に配置した。これにより、自動運転中の表示を行うとともに、車両周囲の人とコミュニケーションをとることができる車両用灯具１０１０を実現できる。 As described above, in the vehicle lamp 1010 according to the second embodiment, the automatic driving marker lamp unit 1018 and the automatic driving signal lamp unit 1020 are arranged vertically with a predetermined distance. As a result, it is possible to realize the vehicular lamp 1010 that can display the automatic driving and can communicate with the people around the vehicle.
　上述の第２実施形態では、図１２に示すように、自動運転マーカ用灯具ユニット１０１８が上方に配置され、自動運転シグナル用灯具ユニット１０２０が下方に配置されているが、逆に、自動運転シグナル用灯具ユニット１０２０が上方に配置され、自動運転マーカ用灯具ユニット１０１８が下方に配置されてもよい。 In the above-described second embodiment, as shown in FIG. 12, the automatic driving marker lamp unit 1018 is arranged at the upper side and the automatic driving signal lamp unit 1020 is arranged at the lower side. The lamp unit 1020 may be arranged above, and the automatic driving marker lamp unit 1018 may be arranged below.
［第３実施形態］
　図１５は、本発明の第３実施形態に係る車両用灯具１２１０を搭載した車両１２００の背面図である。この車両１２００は、レベル３の自動運転に対応した個人所有車（ＰＯＶ：Personally Owned Vehicle）である。 [Third Embodiment]
FIG. 15 is a rear view of a vehicle 1200 equipped with a vehicle lamp 1210 according to the third embodiment of the present invention. This vehicle 1200 is a personally owned vehicle (POV) that supports level 3 autonomous driving.
　車両用灯具１２１０は、ターコイズ色光を発光する自動運転マーカ用灯具ユニット１２１８と、赤色光を発光する標識灯ユニット１２２０と、を備える。標識灯ユニット１２２０は、テール＆ストップランプとして機能する。 The vehicle lamp 1210 includes an automatic driving marker lamp unit 1218 that emits turquoise color light and a marker lamp unit 1220 that emits red light. The marker lamp unit 1220 functions as a tail and stop lamp.
　本発明者は、自動運転マーカ用灯具ユニット１２１８と標識灯ユニット１２２０を備える車両用灯具１２１０を開発する過程において、以下のような課題を認識した。ターコイズ色と赤色は補色の関係にあるため、自動運転マーカ用灯具ユニット１２１８と標識灯ユニット１２２０を隣接して配置した場合、ターコイズ色光と赤色光が混色して白色光として認識される可能性がある。これは、歩行者や他の車両のドライバーに誤認識を与える可能性があるため、好ましくない。 The present inventor has recognized the following problems in the process of developing the vehicle lamp 1210 including the automatic driving marker lamp unit 1218 and the marker lamp unit 1220. Since the turquoise color and the red color have a complementary color relationship, when the automatic driving marker lamp unit 1218 and the marker light unit 1220 are arranged adjacent to each other, the turquoise color light and the red light may be mixed to be recognized as white light. is there. This is not preferable because it may give erroneous recognition to pedestrians and drivers of other vehicles.
　そこで、本第３実施形態においては、自動運転マーカ用灯具ユニット１２１８と標識灯ユニット１２２０は、互いの発光領域が所定の距離Ｄ以上離間するように配置される。所定の距離Ｄは、自動運転マーカ用灯具ユニット１２１８からのターコイズ色光と標識灯ユニット１２２０からの赤色光が白色光と誤認識されない距離であり、実験やシミュレーションにより適宜設定できる。本発明者が検討を行ったところ、所定の距離Ｄを１００ｍｍ以上とすれば白色光の誤認識が起こり難いことが分かった。 Therefore, in the third embodiment, the automatic driving marker lamp unit 1218 and the marker lamp unit 1220 are arranged such that their light emitting areas are separated from each other by a predetermined distance D or more. The predetermined distance D is a distance at which the turquoise light from the automatic driving marker lamp unit 1218 and the red light from the marker lamp unit 1220 are not erroneously recognized as white light, and can be appropriately set by experiments or simulations. As a result of examination by the present inventor, it was found that erroneous recognition of white light is unlikely to occur when the predetermined distance D is 100 mm or more.
　このように、本第３実施形態に係る車両用灯具１２１０によれば、自動運転マーカ用灯具ユニット１２１８の発光領域と標識灯ユニット１２２０の発光領域を所定の距離Ｄ以上離間させることにより、ターコイズ色光と赤色光が白色光に誤認識される事態を防ぐことができるので、安全性を向上することができる。 As described above, according to the vehicle lamp 1210 according to the third embodiment, the turquoise color light is generated by separating the light emitting area of the automatic driving marker lamp unit 1218 from the light emitting area of the marker lamp unit 1220 by a predetermined distance D or more. Since it is possible to prevent the red light from being erroneously recognized as white light, it is possible to improve safety.
　上述したように、レベル５の完全自動運転は、システムが場所の制限なく交通状況を認知して、運転に関わる全ての操作を行うものである。ドライバーが運転を行う必要が完全になくなるため、運転席を排除した車両が提案されている。運転席の無い完全自動運転車では、車両に前後という概念が無くなり、周囲の状況に応じて進行方向が切り替わることが想定される。従来のヘッドランプやリヤランプは、車両の前後方向の一方を照射することを目的として設計されているため、このような完全自動運転車に対応することは難しい。そこで、本発明者は、自動運転車に適した車両用灯具を発明した。 As mentioned above, in level 5 fully automatic driving, the system recognizes traffic conditions without restrictions on location and performs all driving-related operations. A vehicle without a driver's seat has been proposed because the driver does not have to drive. In a fully self-driving vehicle without a driver's seat, the concept of front and rear of the vehicle disappears, and it is assumed that the traveling direction switches depending on the surrounding situation. Conventional headlamps and rear lamps are designed to illuminate one of the front and rear directions of the vehicle, so it is difficult to support such a fully autonomous vehicle. Therefore, the present inventor has invented a vehicular lamp suitable for an autonomous vehicle.
　図１６は、照射光色可変灯具ユニット１０２６の構成を説明するための概略垂直断面図である。上述したように、各照射光色可変灯具ユニット１０２６は、車両進行方向に照射すべき白色光と、車両進行方向と逆方向に照射すべき赤色光とのいずれかを照射可能である。車両進行方向に照射すべき白色光とは、通常のヘッドランプに求められる法規を満たす色および強度の光である。また、車両進行方向と逆方向に照射すべき赤色光とは、通常のリヤランプに求められる法規を満たす色および強度の光である。 FIG. 16 is a schematic vertical sectional view for explaining the configuration of the irradiation light color variable lamp unit 1026. As described above, each irradiation light color variable lamp unit 1026 can emit either white light to be emitted in the vehicle traveling direction or red light to be emitted in the opposite direction to the vehicle traveling direction. The white light to be emitted in the traveling direction of the vehicle is light of a color and intensity that meets the regulations required for ordinary headlamps. Further, the red light to be emitted in the direction opposite to the traveling direction of the vehicle is light of a color and intensity that meets the regulations required for ordinary rear lamps.
　照射光色可変灯具ユニット１０２６は、白色光を照射可能な白色光源ユニット１０３４と、白色光を赤色光に変換する光色変換部材１０３６と、白色光源ユニット１０３４に対して光色変換部材１０３６を可動させて、白色光と赤色光とのいずれかを灯具前方に照射させる可動機構１０３８と、を備える。 The irradiation light color variable lamp unit 1026 includes a white light source unit 1034 that can emit white light, a light color conversion member 1036 that converts white light into red light, and a light color conversion member 1036 that is movable with respect to the white light source unit 1034. The movable mechanism 1038 for irradiating the front of the lamp with either white light or red light.
　白色光源ユニット１０３４は、白色ＬＥＤ１０４０と、白色ＬＥＤ１０４０からの光を制御するインナーレンズ１０４２とを備える。可動機構１０３８は、光色変換部材１０３６の回転軸１０４３と、回転軸１０４３まわりに光色変換部材１０３６を９０°回転させるアクチュエータ（図示せず）とを備える。可動機構１０３８により、光色変換部材１０３６は、白色光源ユニット１０３４の光照射経路上の位置（図１６で実線で図示）と、白色光源ユニット１０３４の光照射経路から退避した位置（図１６で破線で図示）とのいずれかをとることができる。 The white light source unit 1034 includes a white LED 1040 and an inner lens 1042 that controls light from the white LED 1040. The movable mechanism 1038 includes a rotation shaft 1043 of the light color conversion member 1036 and an actuator (not shown) that rotates the light color conversion member 1036 by 90° around the rotation shaft 1043. Due to the movable mechanism 1038, the light color conversion member 1036 is moved to a position on the light irradiation path of the white light source unit 1034 (shown by a solid line in FIG. 16) and a position retracted from the light irradiation path of the white light source unit 1034 (broken line in FIG. 16). (Shown in FIG. 2) can be used.
　可動機構１０３８は、車両１１００のＥＣＵからの車両進行方向の情報に基づいて、光色変換部材１０３６を回転させる。例えば、車両１１００の進行方向が正面側である場合、可動機構１０３８は、光色変換部材１０３６を白色光源ユニット１０３４の光照射経路から退避させる。これにより、車両用灯具１０１０の前方に白色光を照射することができる。一方、車両１１００の進行方向が背面側である場合、可動機構１０３８は、光色変換部材１０３６を白色光源ユニット１０３４の光照射経路上に位置させる。これにより、白色光源ユニット１０３４からの白色光が光色変換部材１０３６で赤色光に変換されるので、車両用灯具１０１０の前方に赤色光を照射することができる。 The movable mechanism 1038 rotates the light color conversion member 1036 based on the information on the vehicle traveling direction from the ECU of the vehicle 1100. For example, when the traveling direction of the vehicle 1100 is the front side, the movable mechanism 1038 retracts the light color conversion member 1036 from the light irradiation path of the white light source unit 1034. As a result, white light can be emitted in front of the vehicular lamp 1010. On the other hand, when the traveling direction of the vehicle 1100 is the rear side, the movable mechanism 1038 positions the light color conversion member 1036 on the light irradiation path of the white light source unit 1034. As a result, the white light from the white light source unit 1034 is converted into red light by the light color conversion member 1036, so that the red light can be emitted to the front of the vehicular lamp 1010.
