Description

本発明は、自動運転状態であることを、車両の周囲全方向に通知できる自動運転車両に関する。 The present invention relates to an autonomous driving vehicle capable of notifying that the vehicle is in an autonomous driving state in all directions around the vehicle.

近年、運転者の負担の軽減や運転ミスによる事故防止等のため、自動運転車両の開発が進められている。しかし、自動運転車両が他の車両とともに公道を走るためには、車両が自動運転状態であることを周囲の車両や歩行者（以下、「周囲の車両等」と記載する）に通知する、新たなコミュニケーション手段が必要である。 In recent years, in order to reduce the burden on the driver and prevent accidents due to driving mistakes, the development of self-driving vehicles has been advanced. However, in order for an autonomous vehicle to run on a public road together with other vehicles, it notifies the surrounding vehicles and pedestrians (hereinafter referred to as "surrounding vehicles, etc.") that the vehicle is in an autonomous driving state. Communication means are needed.

新たなコミュニケーション手段としては、光（ランプ）を活用する方法が知られている。例えば、特許文献１には、車両を駐車エリアへ退避させる場合に、自動運転中であることを後続車へ通知するため、ハザードランプを活用する技術が記載されている。 As a new communication means, a method of utilizing light (lamp) is known. For example, Patent Literature 1 describes a technique of utilizing a hazard lamp in order to notify a succeeding vehicle that the vehicle is being automatically driven when the vehicle is evacuated to a parking area.

特開２０１６−１１５３５６号公報JP, 2016-115356, A

しかし、特許文献１の自動運転車両では、後続車への通知は行えるものの、前方、左右の車両や歩行者には通知を行えないという問題があった。また、周囲全ての方向へ通知を行うために新たなランプを搭載すると、搭載位置によっては車両のデザイン性を低下させる恐れがあった。そのうえ、ランプ搭載のために専用のスペースが必要になるので、今度は車両の小型化が難しくなるという問題もあった。 However, the automatic driving vehicle of Patent Document 1 has a problem in that it is not possible to notify the vehicles in front, left and right, and pedestrians, although the following vehicles can be notified. In addition, if a new lamp is mounted to notify all directions in the surroundings, the design of the vehicle may be deteriorated depending on the mounting position. In addition, since a dedicated space is required to mount the lamp, it is difficult to reduce the size of the vehicle.

そこで、本発明の目的は、車両のデザイン性を保ちつつ、専用のスペースを必要とすることなく、自車両の自動運転状態を通知することが可能な自動運転車両を提供することにある。 Therefore, it is an object of the present invention to provide an automatic driving vehicle capable of notifying the automatic driving state of the own vehicle without requiring a dedicated space while maintaining the design of the vehicle.

上記課題を解決するために、本発明の自動運転車両は、車体に取り付けられる灯具ハウジングに、車両の周辺を照明するための光を発生する第１光源と、車両の自動運転状態を知らせるための光を発生する第２光源とが設けられていることを特徴とする。 In order to solve the above-mentioned problems, an automatic driving vehicle according to the present invention provides a lamp housing attached to a vehicle body with a first light source for generating light for illuminating the periphery of the vehicle and an automatic driving state of the vehicle. A second light source that emits light is provided.

ここで、周囲の車両等が第１および第２光源が発生した光を容易に識別できるように、第１および第２光源が、互いに異なる色の光を発生するのが好適である。また、第１および第２光源が、互いに異なる周期の点滅光を発生するように、各光源の光出力を制御しても良い。 Here, it is preferable that the first and second light sources generate lights of different colors so that the surrounding vehicles and the like can easily distinguish the light generated by the first and second light sources. Further, the light output of each light source may be controlled so that the first and second light sources generate blinking light of different periods.

灯具ハウジングが取り付けられる車体上の部位は、特に限定されないが、既存の車両用灯具を設置するために指定されている部位であるのが望ましい。
例えば、ヘッドランプが設置される車体の前面左右の部位、リアコンビネーションランプが設置される車体の背面左右の部位、ハイマウントストップランプが設置される車体の背面高所の部位、ターンシグナルランプが設置される車体の前後左右の各部位を挙げることができる。The part on the vehicle body to which the lamp housing is attached is not particularly limited, but is preferably a part designated for installing an existing vehicle lamp.
For example, the front left and right parts of the vehicle where the headlamps are installed, the rear left and right parts of the vehicle where the rear combination lamps are installed, the rear high parts of the vehicle where the high mount stop lamps are installed, and the turn signal lamps are installed. The front, rear, left and right parts of the vehicle body can be mentioned.

特に、ターンシグナルランプは、車両の進行方向を光で意志表示できる部位に設置されている点でコミュニケーション用灯具として活用し得る。なかでも、ドアミラー用のサイドターンシグナルランプは、車体の左右両側方へ張り出すように設置されるため、２つの灯具のみで車両の周囲全方向に自動運転状態を通知できる。したがって、本発明の好ましい実施例では、第１および第２光源が、左右のサイドターンシグナルランプの灯具ハウジングにそれぞれ内蔵されている。加えて、第１および第２光源が、左右のフロントターンシグナルランプの灯具ハウジングと、左右のリアターンシグナルランプの灯具ハウジングにそれぞれ内蔵されていても良い。 In particular, the turn signal lamp can be used as a communication lamp because it is installed at a portion where the vehicle's traveling direction can be indicated by light. Above all, since the side turn signal lamp for the door mirror is installed so as to project to the left and right sides of the vehicle body, only two lamps can notify the automatic driving state in all directions around the vehicle. Therefore, in the preferred embodiment of the present invention, the first and second light sources are respectively incorporated in the lamp housings of the left and right side turn signal lamps. In addition, the first and second light sources may be incorporated in the left and right front turn signal lamp lamp housings and the left and right rear turn signal lamp lamp housings, respectively.

第１および第２光源をターンシグナルランプに設ける場合は、車両の左折時に、車体の左側において第１光源を点滅させた状態で第２光源を消灯させ、車体の右側において第１光源を消灯させた状態で第２光源を点灯させ、車両の右折時に、車体の右側において第１光源を点滅させた状態で第２光源を消灯させ、車体の左側において第１光源を消灯させた状態で第２光源を点灯させるための制御を行う電子制御装置を備えているのが好ましい。 When the turn signal lamp is provided with the first and second light sources, when the vehicle turns left, the second light source is turned off while the first light source is blinking on the left side of the vehicle body, and the first light source is turned off on the right side of the vehicle body. When the vehicle turns right, the second light source is turned off while the first light source is blinking on the right side of the vehicle body, and the second light source is turned off on the left side of the vehicle body when the vehicle turns right. It is preferable to include an electronic control device that performs control for turning on the light source.

本発明によれば、灯具ハウジングに第１，２光源を設け、第２光源の発光によって自動運転状態を知らせることとしたため、車両のデザイン性を損なうこと無く、専用スペースを要することもなく、自車両の自動運転状態を他車両等に的確に通知することができるという優れた効果がある。特に、第１，２光源を左右のサイドターンシグナルランプに設けた場合は、自動運転状態を車両の周囲全方向に確実に通知をすることができるという効果もある。 According to the present invention, the first and second light sources are provided in the lamp housing, and the automatic driving state is notified by the light emission of the second light source. Therefore, the design of the vehicle is not impaired, no dedicated space is required, and There is an excellent effect that the automatic driving state of the vehicle can be accurately notified to other vehicles. In particular, when the first and second light sources are provided on the left and right side turn signal lamps, there is an effect that the automatic driving state can be surely notified in all directions around the vehicle.

以下、本発明を具体化した一実施形態を図面に基づいて説明する。図１に示す自動運転車両１には、車両１の前方を照明するＨＬ（ヘッドランプ）２と、車両１の後方を照明するＲＣＬ（リアコンビネーションランプ）５と、ドアミラー１８に設けられた方向指示器であるＳＴＳＬ（サイドターンシグナルランプ）４とが設けられている。ＨＬ２には、車体前端の方向指示器として機能するＦＴＳＬ（フロントターンシグナルランプ）３と、昼間に点灯するＤＲＬ（デイタイム・ランニング・ランプ）２２とが設けられている。ＲＣＬ５には、車体後端の方向指示器として機能するＲＴＳＬ（リアターンシグナルランプ）６が設けられている。 An embodiment of the present invention will be described below with reference to the drawings. In the autonomous driving vehicle 1 shown in FIG. 1, an HL (head lamp) 2 that illuminates the front of the vehicle 1, an RCL (rear combination lamp) 5 that illuminates the rear of the vehicle 1, and a direction indicator provided on a door mirror 18. STSL (side turn signal lamp) 4, which is a container, is provided. The HL 2 is provided with an FTSL (front turn signal lamp) 3 that functions as a turn indicator at the front end of the vehicle body, and a DRL (daytime running lamp) 22 that lights up in the daytime. The RCL 5 is provided with an RTSL (rear turn signal lamp) 6 that functions as a direction indicator at the rear end of the vehicle body.

図２に示す自動運転車両１では、左右のＦＴＳＬ３Ｒ，３Ｌ、左右のＳＴＳＬ４Ｒ，４Ｌ、および左右のＲＴＳＬ６Ｒ，６Ｌに、それぞれ、車両１の前方、側方および後方を照明するための光を発生する第１光源７と、車両１の自動運転状態を知らせるための光を発生する第２光源８とが設けられている。第１光源７および第２光源８は、各灯具のハウジング（図４にＳＴＳＬ４のハウジング９を代表的に示す）に内蔵されている。また、第１および第２光源７，８には互いに異なる色の光を発生するＬＥＤが用いられている。例えば、第１光源７にアンバー色の光を発生するＬＥＤを使用し、第２光源８にグリーン色の光を発生するＬＥＤを使用することができる。 In the autonomous driving vehicle 1 shown in FIG. 2, lights for illuminating the front, side, and rear of the vehicle 1 are generated in the left and right FTSLs 3R, 3L, the left and right STSLs 4R, 4L, and the left and right RTSLs 6R, 6L, respectively. A first light source 7 and a second light source 8 that emits light for indicating an automatic driving state of the vehicle 1 are provided. The first light source 7 and the second light source 8 are built in the housing of each lamp (the housing 9 of the STSL 4 is representatively shown in FIG. 4). Further, LEDs that generate lights of different colors are used for the first and second light sources 7 and 8. For example, an LED that emits amber light can be used for the first light source 7, and an LED that emits green light can be used for the second light source 8.

したがって、図２に示す自動運転車両１によれば、車体周りの６箇所に設置されたターンシグナルランプ３Ｒ，３Ｌ，４Ｒ，４Ｌ，６Ｒ，６Ｌに、それぞれ異なる色の光を発生する第１光源７と第２光源８を設けたため、第１光源７による照明機能に第２光源８によるコミュニケーション機能を追加して、自車両１の自動運転状態を車両１の周囲全方向に通知し、自動運転走行時の安全性を高めることができる。また、第１および第２光源７，８が車両に既設の灯具ハウジング９に内蔵されているため、車両１の外観に影響を及ぼすことなく、車両１のデザイン性を高く保つことができるとともに、自動運転状態を知らせるために新たな設置スペースを確保する必要がないため、車両１の小型・軽量化にも柔軟に対応できるという優れた効果がある。 Therefore, according to the autonomous driving vehicle 1 shown in FIG. 2, the turn signal lamps 3R, 3L, 4R, 4L, 6R, 6L installed at six locations around the vehicle body emit the lights of different colors. 7 and the second light source 8 are provided, the communication function by the second light source 8 is added to the illumination function by the first light source 7 to notify the automatic driving state of the own vehicle 1 to all directions around the vehicle 1 to perform automatic driving. It is possible to improve safety while driving. In addition, since the first and second light sources 7 and 8 are built in the existing lamp housing 9 of the vehicle, the design of the vehicle 1 can be kept high without affecting the appearance of the vehicle 1. Since it is not necessary to secure a new installation space for informing the autonomous driving state, there is an excellent effect that the vehicle 1 can be flexibly made smaller and lighter.

図３に示す自動運転車両１では、第１および第２光源７，８が左右のドアミラー１８のＳＴＳＬ４Ｒ，４Ｌのみに設けられている。そして、第１および第２光源７，８が、車幅方向の外側へ最も離れた位置から車両１の前方、側方、後方を含む広範囲に照明用のアンバー色の光と、自動運転通知用のグリーン色の光とを発生するようになっている。したがって、図３に示す自動運転車両１によれば、特に、２つのＳＴＳＬ４Ｒ，４Ｌのみの安価な手段によって、自動運転状態を自車両１の周囲広範囲に通知することができる。その他の作用効果は、図２の自動運転車両１と同様である。 In the autonomous driving vehicle 1 shown in FIG. 3, the first and second light sources 7 and 8 are provided only on the STSLs 4R and 4L of the left and right door mirrors 18. Then, the first and second light sources 7 and 8 are used for amber light for illumination in a wide range including the front, the side, and the rear of the vehicle 1 from the position farthest to the outside in the vehicle width direction, and the automatic driving notification. It is designed to emit green light. Therefore, according to the self-driving vehicle 1 shown in FIG. 3, it is possible to notify the self-driving state to a wide range around the self-vehicle 1, particularly by an inexpensive means including only two STSLs 4R and 4L. Other functions and effects are similar to those of the autonomous driving vehicle 1 of FIG.

図４〜図１０は、自動運転通知機能を備えたＳＴＳＬ４の構成を詳細に示す。図４に示すように、ＳＴＳＬ４は、ドアミラー１８に内蔵される灯具ハウジング９を備えている。灯具ハウジング９は車幅方向に長く形成され、車幅方向の内端部に第１，２光源７，８を保持する基板２３が設けられている。また、灯具ハウジング９の内側には、車幅方向に長い導光レンズ１４が設置され、第１，２光源７，８からの光を導いて、車両前方、側方および後方へ出射するようになっている。 4 to 10 show in detail the configuration of the STSL 4 having the automatic driving notification function. As shown in FIG. 4, the STSL 4 includes a lamp housing 9 built in the door mirror 18. The lamp housing 9 is formed to be long in the vehicle width direction, and a substrate 23 that holds the first and second light sources 7 and 8 is provided at an inner end portion in the vehicle width direction. Further, a light guide lens 14 which is long in the vehicle width direction is installed inside the lamp housing 9 so that the light from the first and second light sources 7 and 8 is guided and emitted to the front, side and rear of the vehicle. Has become.

図５（ａ）に示す基板２３には、第１光源７としての、アンバー色に発光する複数のＬＥＤ１１と、第２光源８としての、グリーン色に発光する複数のＬＥＤ１２が交互に配置されている。図５（ｂ）に示す基板２３には、複数のマルチカラーＬＥＤ１３が配置され、アンバー色の光とグリーン色の光とを混色により生成し、第１光源７および第２光源８の発光色を切替えて照射できるようになっている。この場合、多様な発光色を生成し、自動運転の状況に応じて、第１および第２光源７，８の発光色を柔軟に設定し、周囲の車両等とさらに細やかなコミュニケーションができるという効果がある。 On the substrate 23 shown in FIG. 5A, a plurality of LEDs 11 emitting amber color as the first light source 7 and a plurality of LEDs 12 emitting green color as the second light source 8 are alternately arranged. There is. A plurality of multi-color LEDs 13 are arranged on the substrate 23 shown in FIG. 5B, and amber color light and green color light are generated by color mixing to generate the emission colors of the first light source 7 and the second light source 8. It can be switched and irradiated. In this case, various emission colors are generated, and the emission colors of the first and second light sources 7 and 8 are flexibly set according to the situation of automatic driving, and more detailed communication with surrounding vehicles and the like can be performed. There is.

図６（ａ）に示す導光レンズ１４は、拡散材１５を封入した透明材料で成形されている。こうすれば、導光レンズ１４を通過する第１および第２光源７，８の光によってＳＴＳＬ４の全域を明るく発光させることができる。また、図６（ｂ）に示すように、導光レンズ１４の裏面に点刻ステップ１６を設け、第１および第２光源７，８からの光を点刻ステップ１６で反射させて、ＳＴＳＬ４の全域を発光させるように構成しても良い。 The light guide lens 14 shown in FIG. 6A is formed of a transparent material in which a diffusion material 15 is enclosed. In this way, the light of the first and second light sources 7, 8 passing through the light guide lens 14 can cause the entire area of the STSL 4 to be brightly emitted. Further, as shown in FIG. 6B, the stippling step 16 is provided on the back surface of the light guide lens 14, and the light from the first and second light sources 7 and 8 is reflected at the stippling step 16 so that the STSL 4 has It may be configured to emit light over the entire area.

図７に示すＳＴＳＬ４では、導光レンズ１４の長手方向の複数位置に第２光源８が増設されている。各第２光源８には、図８に示すように、例えばグリーン色など、自動運転状態を通知する色の光を発生するＬＥＤ１２が用いられ、導光レンズ１４の幅方向に複数個のＬＥＤ１２が基板２３上に保持されている。この構成によれば、第２光源８の増設により、導光レンズ１４の輝度を強化し、周囲の車両等に自動運転中であることをより確実に通知することができるという効果がある。 In the STSL 4 shown in FIG. 7, the second light source 8 is additionally installed at a plurality of positions in the longitudinal direction of the light guide lens 14. For each second light source 8, as shown in FIG. 8, an LED 12 that emits light of a color that notifies an automatic driving state, such as a green color, is used, and a plurality of LEDs 12 are arranged in the width direction of the light guide lens 14. It is held on the substrate 23. According to this configuration, by adding the second light source 8, the brightness of the light guide lens 14 can be enhanced, and it is possible to more reliably notify the surrounding vehicles and the like that the vehicle is in automatic driving.

図９は、ＳＴＳＬ４の制御システムを示す。ここでは、自動運転車両１のＥＣＵ（電子制御ユニット）２５が、ＳＴＳＬ４の第１，２光源７，８を制御する電子制御装置として作動する。ＥＣＵ２５は、ＣＡＮ（コントローラー・エリア・ネットワーク）２６を通じて車両１の各部から自動運転状態を示す検知信号を取得し、自動運転状態の判別結果に従い、サイドターンドライバ２７を介して第１光源７の点滅／消灯を制御するとともに、通知ランプドライバ２８を介して第２光源８の点灯／消灯を制御するように構成されている。なお、図９に示す制御システムは、ＳＴＳＬ４以外の自動運転通知機能を備えた車両用灯具における第１および第２光源７，８の光出力制御にも適用することができる。 FIG. 9 shows a control system of STSL4. Here, the ECU (electronic control unit) 25 of the autonomous driving vehicle 1 operates as an electronic control device that controls the first and second light sources 7 and 8 of the STSL 4. The ECU 25 acquires a detection signal indicating an automatic driving state from each part of the vehicle 1 through a CAN (Controller Area Network) 26, and blinks the first light source 7 via the side turn driver 27 according to the determination result of the automatic driving state. It is configured to control turning on/off and also controlling turning on/off of the second light source 8 via the notification lamp driver 28. The control system shown in FIG. 9 can also be applied to the light output control of the first and second light sources 7 and 8 in the vehicular lamp having an automatic driving notification function other than STSL4.

図１０は、ＥＣＵ２５によるＳＴＳＬ４の制御を例示するフローチャートである。自動運転車両１のウインカーレバー（図示略）がＯＮすると（Ｓ１：Ｙｅｓ）、通常どおり、ＳＴＳＬ４の第１光源７がアーバン色で点滅する（Ｓ２）。ウインカーレバーがＯＦＦであるときには（Ｓ１：Ｎｏ）、自動運転中であるか否かが判断される（Ｓ３）。そして、自動運転中である場合は、第２光源８がグリーン色で点灯し（Ｓ４）、自車両１が自動運転状態であることを周囲の他車両等へ通知する。自動運転中でない場合は、第１および第２光源７，８が共に消灯する（Ｓ５）。 FIG. 10 is a flowchart illustrating the control of the STSL 4 by the ECU 25. When the winker lever (not shown) of the autonomous driving vehicle 1 is turned on (S1: Yes), the first light source 7 of the STSL 4 blinks in an urban color as usual (S2). When the winker lever is OFF (S1: No), it is determined whether or not automatic driving is being performed (S3). Then, when the vehicle is in automatic driving, the second light source 8 is lit in green (S4), and the surrounding other vehicles are notified that the vehicle 1 is in the automatic driving state. When the automatic operation is not being performed, both the first and second light sources 7 and 8 are turned off (S5).

なお、図１０に示す制御は、ＳＴＳＬ４以外の自動運転通知機能を備えた車両用灯具の制御にも適用することができる。また、コミュニケーションランプとしてのＦＴＳＬ３、ＳＴＳＬ４、ＲＴＳＬ６において、第２光源８の光出力を自車両１の周辺の他車両や歩行者とのアイコンタクトまたはコミニュケーションに利用することもできる。例えば、自車両１が、他車両や歩行者に進路を譲らない場合に、第２光源８を早い周期（例えば、３Ｈｚ）で点滅させ、警告を発して走り去ったり、他車両や歩行者に進路を譲る場合に、第２光源８を遅い周期（例えば、０．５Ｈｚ）で点滅させて停車したりするなどの制御を行うことができる。 The control shown in FIG. 10 can also be applied to the control of a vehicular lamp having an automatic driving notification function other than STSL4. In addition, in the FTSL3, STSL4, and RTSL6 as communication lamps, the light output of the second light source 8 can be used for eye contact or communication with other vehicles around the vehicle 1 or pedestrians. For example, when the host vehicle 1 does not give way to another vehicle or a pedestrian, the second light source 8 blinks at an early cycle (for example, 3 Hz) to issue a warning and run away, or to the other vehicle or a pedestrian. In the case of giving up, the control such as stopping the vehicle by blinking the second light source 8 at a slow cycle (for example, 0.5 Hz) can be performed.

図１１は、車両１の左折時および右折時におけるＥＣＵ２５による左右のＳＴＳＬ４Ｒ，４Ｌ（図３参照）の点灯制御を示す。車両１の右折時には、車体左側のＳＴＳＬ４Ｌにおいて、第１光源７を消灯させた状態で第２光源８を点灯し、車体右側のＳＴＳＬ４Ｒにおいて、第２光源８を消灯させた状態で第１光源７を点滅させる。車両１の左折時には、車体右側のＳＴＳＬ４Ｒにおいて、第１光源７を消灯させた状態で第２光源８を点灯させ、車体左側のＳＴＳＬ４Ｌにおいて、第１光源７を消灯させた状態で第２光源８を点灯させる。こうすれば、自動運転中であっても、ＳＴＳＬ５の方向指示機能を損なうことなく自動運転状態を周辺車両等へ的確に通知することができる。 FIG. 11 shows lighting control of the left and right STSLs 4R, 4L (see FIG. 3) by the ECU 25 when the vehicle 1 is turning left and turning right. When the vehicle 1 turns right, the second light source 8 is turned on in the STSL 4L on the left side of the vehicle body with the first light source 7 turned off, and the first light source 7 is turned off in the STSL 4R on the right side of the vehicle body with the second light source 8 turned off. Blink. When the vehicle 1 turns left, in the STSL 4R on the right side of the vehicle body, the second light source 8 is turned on while the first light source 7 is off, and in the STSL 4L on the left side of the vehicle body, the second light source 8 is turned off. Light up. By doing so, even during automatic driving, it is possible to accurately notify the surrounding vehicles and the like of the automatic driving state without impairing the direction indicating function of the STSL 5.

なお、本発明は、上記実施形態に限定されるものではなく、例えば、グリーン色を他の発光色に置き換えたり、ＤＲＬ２２（図１参照）に第１および第２光源７，８を設けたりするなど、発明の趣旨を逸脱しない範囲で、各部の構成を適宜変更して実施することも可能である。 It should be noted that the present invention is not limited to the above-described embodiment, and for example, the green color is replaced with another emission color, or the DRL 22 (see FIG. 1) is provided with the first and second light sources 7 and 8. For example, the configuration of each unit can be appropriately changed and implemented without departing from the spirit of the invention.
