　運転モードは、自動運転モードと、手動運転モードと、からなる。自動運転モードは、完全自動運転モードと、高度運転支援モードと、運転支援モードとからなる。完全自動運転モードでは、車両用システム２がステアリング制御、ブレーキ制御およびアクセル制御の全ての走行制御を自動的に行うと共に、運転手は車両１を運転できる状態にはない。高度運転支援モードでは、車両用システム２がステアリング制御、ブレーキ制御およびアクセル制御の全ての走行制御を自動的に行うと共に、運転手は車両１を運転できる状態にはあるものの車両１を運転しない。運転支援モードでは、車両用システム２がステアリング制御、ブレーキ制御およびアクセル制御のうち一部の走行制御を自動的に行うと共に、車両用システム２の運転支援の下で運転手が車両１を運転する。一方、手動運転モードでは、車両用システム２が走行制御を自動的に行わないと共に、車両用システム２の運転支援なしに運転手が車両１を運転する。 The operation mode consists of an automatic operation mode and a manual operation mode. The automatic driving mode consists of a fully automatic driving mode, an advanced driving assistance mode, and a driving assistance mode. In the fully automatic driving mode, the vehicle system 2 automatically performs all driving control including steering control, brake control and accelerator control, and the driver is not in a state to drive the vehicle 1 . In the advanced driving assistance mode, the vehicle system 2 automatically performs all driving control including steering control, brake control and accelerator control, and the driver does not drive the vehicle 1 although the vehicle 1 is ready to be driven. In the driving assistance mode, the vehicle system 2 automatically performs part of driving control out of steering control, brake control, and accelerator control, and the driver drives the vehicle 1 under the driving assistance of the vehicle system 2. . On the other hand, in the manual driving mode, the vehicle system 2 does not automatically perform travel control, and the driver drives the vehicle 1 without the driving assistance of the vehicle system 2 .
　また、車両１の運転モードは、運転モード切替スイッチを操作することで切り替えられてもよい。この場合、車両制御部３は、運転モード切替スイッチに対する運転手の操作に応じて、車両１の運転モードを４つの運転モード（完全自動運転モード、高度運転支援モード、運転支援モード、手動運転モード）の間で切り替える。また、車両１の運転モードは、自動運転車が走行可能である走行可能区間や自動運転車の走行が禁止されている走行禁止区間についての情報または外部天候状態についての情報に基づいて自動的に切り替えられてもよい。この場合、車両制御部３は、これらの情報に基づいて車両１の運転モードを切り替える。さらに、車両１の運転モードは、着座センサや顔向きセンサ等を用いることで自動的に切り替えられてもよい。この場合、車両制御部３は、着座センサや顔向きセンサからの出力信号に基づいて、車両１の運転モードを切り替える。 Also, the driving mode of the vehicle 1 may be switched by operating a driving mode changeover switch. In this case, the vehicle control unit 3 changes the driving mode of the vehicle 1 into four driving modes (fully automatic driving mode, advanced driving assistance mode, driving assistance mode, manual driving mode) according to the driver's operation of the driving mode switch. ). In addition, the driving mode of the vehicle 1 is automatically set based on information about drivable sections in which the autonomous vehicle can travel, prohibited sections in which the autonomous vehicle is prohibited from traveling, or information about external weather conditions. may be switched. In this case, the vehicle control unit 3 switches the driving mode of the vehicle 1 based on these pieces of information. Furthermore, the driving mode of the vehicle 1 may be automatically switched by using a seat sensor, face direction sensor, or the like. In this case, the vehicle control unit 3 switches the driving mode of the vehicle 1 based on the output signals from the seating sensor and face direction sensor.
　一方、車両１が手動運転モードで走行する場合、車両制御部３は、アクセルペダル、ブレーキペダルおよびステアリングホイールに対する運転者の手動操作に従って、ステアリング制御信号、アクセル制御信号およびブレーキ制御信号を生成する。このように、手動運転モードでは、ステアリング制御信号、アクセル制御信号およびブレーキ制御信号が運転者の手動操作によって生成されるので、車両１の走行は運転者により制御される。 On the other hand, when the vehicle 1 runs in manual operation mode, the vehicle control unit 3 generates a steering control signal, an accelerator control signal, and a brake control signal according to the driver's manual operation of the accelerator pedal, brake pedal, and steering wheel. Thus, in the manual driving mode, the steering control signal, the accelerator control signal and the brake control signal are generated by the manual operation of the driver, so that the driving of the vehicle 1 is controlled by the driver.
　環境情報取得部１８は、外部装置３０から環境情報を取得する。外部装置３０は、例えば、ユーザが携帯しているスマートフォン、車両１に搭載されたカーナビ装置等の情報端末装置等である。環境情報とは、例えば、ユーザの気分等に関するユーザ気分情報、車両１の周囲の天気に関する天気情報、車内の環境に関する車内環境情報等である。なお、車内環境情報とは、車内の温度に関する車内温度情報、車内の湿度に関する車内湿度情報、車内で流れている音楽に関する車内音楽情報等である。環境情報取得部１８は、外部装置３０から取得した環境情報を、車両制御部３を介して、照明制御部２２に送信する。 The environment information acquisition unit 18 acquires environment information from the external device 30 . The external device 30 is, for example, a smart phone carried by the user, an information terminal device such as a car navigation device mounted on the vehicle 1, or the like. The environment information is, for example, user mood information about the user's mood, weather information about the weather around the vehicle 1, vehicle environment information about the environment inside the vehicle, and the like. The in-vehicle environment information includes in-vehicle temperature information related to the temperature in the vehicle, in-vehicle humidity information related to the humidity in the vehicle, in-vehicle music information related to music being played in the vehicle, and the like. The environment information acquisition unit 18 transmits the environment information acquired from the external device 30 to the lighting control unit 22 via the vehicle control unit 3 .

The vehicle communication lamps 20 are, for example, turn signal lamps, brake lamps, and backup lamps. The vehicle communication lamp 20 is capable of blinking and lighting light with a wavelength of 500 nm or more and x of 0.6 or less in the xy chromaticity diagram to express gratitude. As will be described in detail in the sensory test described later, light with a wavelength of 500 nm or more and x of 0.6 or less in the xy chromaticity diagram gives a warm feeling of gratitude to the traffic participants and gives a warning or the like. It can be recognized by traffic participants as a warm color that does not contain strong emotions.

　図２に戻り、車両用コミュニケーションランプ２０に備わる光源ユニット２１および照明制御部２２について説明する。光源ユニット２１は、ＬＥＤ（Ｌｉｇｈｔ　Ｅｍｉｔｔｉｎｇ　Ｄｉｏｄｅ）素子またはＬＤ（Ｌａｓｅｒ　Ｄｉｏｄｅ）素子によって構成されうる。本実施形態において、光源ユニット２１は、複数の色の光を出射可能な多色光源を含んでいる。なお、多色光源とは、２以上の異なる発光色相を有する光源である。光源ユニット２１の明るさは、光源ユニット２１に含まれる光源に流れる電流値の大きさに比例する。したがって、光源ユニット２１に含まれる光源に流れる電流値が大きいほど、光源ユニット２１は明るい。なお、光源ユニット２１は、少なくとも、第一の光を出射する第一光源と、第一の光の色とは異なる色の第二の光を出射する第二光源と、を有していてもよい。 Returning to FIG. 2, the light source unit 21 and the lighting control section 22 provided in the vehicle communication lamp 20 will be described. The light source unit 21 can be configured by an LED (Light Emitting Diode) element or an LD (Laser Diode) element. In this embodiment, the light source unit 21 includes a polychromatic light source capable of emitting light of multiple colors. A polychromatic light source is a light source having two or more different emission hues. The brightness of the light source unit 21 is proportional to the magnitude of the current flowing through the light source included in the light source unit 21 . Therefore, the larger the current flowing through the light source included in the light source unit 21, the brighter the light source unit 21 becomes. Note that the light source unit 21 may include at least a first light source that emits first light and a second light source that emits second light having a color different from that of the first light. good.
　本実施形態において、多色光源は、いわゆるＲＧＢ光源である。光源ユニット２１は、例えば、ＲＧＢ（赤緑青）の三色光を発光する複数のＬＥＤと、当該ＬＥＤで発光された光を車両１の外部に出射させるためのレンズと、を含んでいる。当該レンズは、例えば、当該ＬＥＤで発光された光を平行な光束として投射させるコンデンサレンズとして構成されうる。光源ユニット２１は、任意の色の光を出射することができるが、本実施形態においては、アンバー色、ピンク色、緑色、黄色等の光を出射する。なお、アンバー色とは、ＪＩＳ規格Ｚ８１１０における黄色のうちの長波長領域と黄赤の短波長領域とからなる領域、安全色彩のＪＩＳ規格Ｚ９１０１による黄色の領域と黄赤の短波長領域に挟まれた領域の色度範囲に該当する色である。 In this embodiment, the polychromatic light source is a so-called RGB light source. The light source unit 21 includes, for example, a plurality of LEDs that emit three colors of RGB (red, green, and blue), and a lens for emitting the light emitted by the LEDs to the outside of the vehicle 1 . The lens can be configured, for example, as a condenser lens that projects the light emitted by the LED as a parallel light beam. The light source unit 21 can emit light of any color, but in this embodiment, it emits light of amber, pink, green, yellow, or the like. The amber color is a region consisting of a long wavelength region of yellow and a short wavelength region of yellow and red in JIS standard Z8110, and a yellow region and a short wavelength region of yellow and red according to JIS standard Z9101 of safety colors. It is a color that corresponds to the chromaticity range of the
　照明制御部２２は、車両制御部３と同様のプロセッサおよびメモリによって構成されていてもよい。照明制御部２２は、光源ユニット２１の動作を制御する。照明制御部２２は、例えば、光源ユニット２１の点消灯が所定の時間間隔で行われるように、光源ユニット２１を制御する。なお、当該所定の時間間隔は、５００ミリ秒から５０００ミリ秒の間で設定される。当該所定の時間間隔は、特に、１０００ミリ秒から２０００ミリ秒の間で設定されるのが好ましい。また、通常動作モードにおいて、光源ユニット２１が消灯状態からフル点灯状態に遷移するまでに要する時間は、２００ミリ秒以内である。なお、フル点灯状態とは、光源ユニット２１が最も明るいときの状態をいう。一方で、感情表出モードにおいて、光源ユニット２１が消灯状態からフル点灯状態に遷移するまでに要する時間については、後述する。 The lighting control unit 22 may be composed of the same processor and memory as the vehicle control unit 3. The lighting control section 22 controls the operation of the light source unit 21 . The lighting controller 22 controls the light source unit 21, for example, so that the light source unit 21 is turned on and off at predetermined time intervals. In addition, the said predetermined time interval is set between 500 milliseconds and 5000 milliseconds. The predetermined time interval is particularly preferably set between 1000 ms and 2000 ms. Further, in the normal operation mode, the time required for the light source unit 21 to transition from the off state to the fully lit state is within 200 milliseconds. Note that the full lighting state refers to a state in which the light source unit 21 is at its brightest. On the other hand, in the emotion expression mode, the time required for the light source unit 21 to transition from the off state to the fully lit state will be described later.
　照明制御部２２は、サンキュースイッチ４が押下されたことにより生成された感情表出信号を、車両制御部３を介して受信する。照明制御部２２は、感情表出信号を受信すると、感情表出モードで、光源ユニット２１を点灯させる。つまり、照明制御部２２は、交通参加者に対して感情情報を伝達する信号（感情表出信号）が入力されたときに、光源ユニット２１を点灯させる。 The lighting control unit 22 receives, via the vehicle control unit 3, the emotion expression signal generated by pressing the thank you switch 4. Upon receiving the emotional expression signal, the lighting control section 22 lights the light source unit 21 in the emotional expression mode. That is, the lighting control unit 22 turns on the light source unit 21 when a signal (emotional expression signal) for conveying emotional information to the traffic participant is input.
　照明制御部２２は、光源ユニット２１から出射される光の色を経時的に変化させるように光源ユニット２１を制御しうる。また、照明制御部２２は、光源ユニット２１の明るさを経時的に変化させるように光源ユニット２１を制御しうる。照明制御部２２は、例えば、光源ユニット２１に含まれる光源に流れる電流値を変化させることで、光源ユニット２１の明るさを変化させる。照明制御部２２は、通常動作モード時において、車両用コミュニケーションランプ２０と通信可能に接続された外部装置３０から取得した環境情報に応じた色の光を出射するように、光源ユニット２１を制御することもできる。 The illumination control section 22 can control the light source unit 21 so as to change the color of the light emitted from the light source unit 21 over time. Also, the illumination control section 22 can control the light source unit 21 so as to change the brightness of the light source unit 21 over time. The illumination control unit 22 changes the brightness of the light source unit 21 by, for example, changing the current value flowing through the light source included in the light source unit 21 . The illumination control unit 22 controls the light source unit 21 so as to emit light of a color according to the environment information acquired from the external device 30 communicably connected to the vehicle communication lamp 20 in the normal operation mode. can also

At time t14, the color of the light emitted from the light source unit 21 is yellow.
　時刻ｔ１４から時刻ｔ１５の間、照明制御部２２は、光源ユニット２１から出射される光に含まれる赤色の光と緑色の光が共に徐々に暗くなるように、光源ユニット２１を制御する。その結果、光源ユニット２１から出射される光は徐々に暗くなる。そして、時刻ｔ１５において、光源ユニット２１は消灯状態になる。 Between time t14 and time t15, the illumination control unit 22 controls the light source unit 21 so that both the red light and the green light included in the light emitted from the light source unit 21 gradually darken.

Therefore, according to the vehicle communication lamp 20, it is possible to reliably make the traffic participants feel the predetermined information such as gratitude.
（第一実施形態の第三実施例）
　次に、図６を参照しつつ、第一実施形態の第三実施例について説明する。なお、本実施例において、第一実施形態の第一実施例と同様の構成については同じ符号を付して説明し、説明が重複する部分については適宜説明を省略する。本実施例は、光源ユニット２１の点灯状態の変化の様子において、第二実施形態の第一実施例と異なる。なお、本実施例においても、車両１のユーザが、車両１の近傍にいる交通参加者に対して謝意を表意するために、時刻ｔ２０において、サンキュースイッチ４を押下したものとする。 (Third example of first embodiment)
Next, a third example of the first embodiment will be described with reference to FIG. In addition, in the present embodiment, the same reference numerals are assigned to the same configurations as in the first embodiment of the first embodiment, and descriptions of overlapping descriptions will be omitted as appropriate. This example differs from the first example of the second embodiment in how the lighting state of the light source unit 21 changes. Also in this embodiment, it is assumed that the user of vehicle 1 presses thank-you switch 4 at time t20 in order to express gratitude to the traffic participants in the vicinity of vehicle 1 .
　図６に例示するように、時刻ｔ２０から時刻ｔ２２までの間、光源ユニット２１は点灯状態である。なお、時刻ｔ２０において、赤色の光を発するＲ光源は、フル点灯状態である。時刻ｔ２０において、光源ユニット２１から出射される光に含まれる赤色の光は、光源ユニット２１から出射される光に含まれる緑色の光よりも明るい。したがって、時刻ｔ２０において、光源ユニット２１から出射される光の色は、アンバー色である。 As illustrated in FIG. 6, the light source unit 21 is in a lighting state from time t20 to time t22. At time t20, the R light source emitting red light is in a full lighting state. At time t<b>20 , the red light contained in the light emitted from the light source unit 21 is brighter than the green light contained in the light emitted from the light source unit 21 . Therefore, at time t20, the color of light emitted from light source unit 21 is amber.
　時刻ｔ２０から時刻ｔ２２までの間、照明制御部２２は、光源ユニット２１から出射される光に含まれる赤色の光が、時間が経過するにつれて徐々に暗くなるように、光源ユニット２１を制御する。一方で、時刻ｔ２０から時刻ｔ２２までの間、照明制御部２２は、光源ユニット２１から出射される光に含まれる緑色の光の明るさが変化しないように、光源ユニット２１を制御する。その結果、時刻ｔ２１において、光源ユニット２１から出射される光に含まれる赤色の光の明るさと緑色の光の明るさは等しくなる。したがって、時刻ｔ２０から時刻ｔ２１に向かうにつれて、光源ユニット２１から出射される光の色はアンバー色から黄色に変化する。 From time t20 to time t22, the illumination control unit 22 controls the light source unit 21 so that the red light contained in the light emitted from the light source unit 21 gradually darkens as time passes. On the other hand, from time t20 to time t22, the illumination control section 22 controls the light source unit 21 so that the brightness of the green light contained in the light emitted from the light source unit 21 does not change. As a result, at time t21, the brightness of the red light and the brightness of the green light included in the light emitted from the light source unit 21 become equal. Therefore, from time t20 to time t21, the color of the light emitted from the light source unit 21 changes from amber to yellow.

From time t30 to time t31, the R light source emitting red light and the G light source emitting green light are in a full lighting state.
　時刻ｔ３１から時刻ｔ３２までの間、照明制御部２２は、光源ユニット２１から出射される光に含まれる赤色の光および緑色の光が、時間が経過するにつれて徐々に暗くなるように、光源ユニット２１を制御する。一方で、時刻ｔ３１から時刻ｔ３２までの間、照明制御部２２は、光源ユニット２１から出射される光に含まれる青色の光が、時間が経過するにつれて徐々に明るくなるように、光源ユニット２１を制御する。したがって、時刻ｔ３１から時刻ｔ３２までの間、光源ユニット２１から出射される光の色は、黄色から白色に近づくように変化する。なお、時刻ｔ３２において、青色の光を発するＢ光源は、フル点灯状態である。 During the period from time t31 to time t32, the lighting control unit 22 controls the light source unit 21 so that the red light and the green light included in the light emitted from the light source unit 21 gradually become darker as time passes. to control.

Therefore, from time t32 to time t33, the light source unit 21 gradually darkens as time passes. At time t33, the light emitted from the light source unit 21 does not contain blue light. Therefore, at time t33, the color of the light emitted from the light source unit 21 is yellow.
　時刻ｔ３３から時刻ｔ３４までの間、光源ユニット２１から出射される光に含まれる赤色の光および緑色の光の明るさは、時間が経過するにつれて徐々に暗くなる。なお、時刻ｔ３３から時刻ｔ３４までの間、光源ユニット２１から出射される光には、青色の光は含まれていない。したがって、時刻ｔ３３から時刻ｔ３４までの間、光源ユニット２１から出射される光の色は黄色である。また、時刻ｔ３３から時刻ｔ３４までの間、光源ユニット２１は、時間が経過するにつれて徐々に暗くなる。時刻ｔ３４において、光源ユニット２１は消灯状態になる。 Between time t33 and time t34, the brightness of the red light and green light contained in the light emitted from the light source unit 21 gradually darkens as time passes.

（第一実施形態の第五実施例）
　次に、図８を参照しつつ、第一実施形態の第五実施例について説明する。なお、本実施例において、第一実施形態の第一実施例と同様の構成については同じ符号を付して説明し、説明が重複する部分については適宜説明を省略する。本実施例は、光源ユニット２１がフル点灯状態でピンク色の光を出射するように構成されている（例えば、ＲＧＢ光源において、Ｒ光源がＧ光源およびＢ光源よりもわずかに多く含まれるように構成されている）点と、光源ユニット２１の点灯状態の変化の様子が異なる点と、で、第一実施形態の第一実施例と異なる。なお、本実施例においても、車両１のユーザが、車両１の近傍にいる交通参加者に対して謝意を表意するために、時刻ｔ４０において、サンキュースイッチ４を押下したものとする。 (Fifth example of the first embodiment)
Next, a fifth example of the first embodiment will be described with reference to FIG. In addition, in the present embodiment, the same reference numerals are assigned to the same configurations as those of the first embodiment of the first embodiment, and the descriptions of overlapping descriptions are omitted as appropriate. In this embodiment, the light source unit 21 is configured to emit pink light in a fully lit state (for example, in the RGB light sources, the R light source is slightly more than the G light source and the B light source). The first embodiment differs from the first example in that it is configured) and that the state of change in the lighting state of the light source unit 21 is different. Also in this embodiment, it is assumed that the user of vehicle 1 presses thank-you switch 4 at time t40 to express gratitude to the traffic participants in the vicinity of vehicle 1. FIG.
　図８に例示するように、時刻ｔ４０から時刻ｔ４１の間、光源ユニット２１は消灯状態である。したがって、時刻ｔ４０から時刻ｔ４１の間、光源ユニット２１の明るさは変化しない。時刻ｔ４１から時刻ｔ４２の間、光源ユニット２１は点灯状態である。なお、時刻ｔ４１から時刻ｔ４２の間、光源ユニット２１はフル点灯状態である。したがって、時刻ｔ４１から時刻ｔ４２の間、光源ユニット２１の明るさは変化しない。 As illustrated in FIG. 8, the light source unit 21 is turned off from time t40 to time t41. Therefore, the brightness of the light source unit 21 does not change from time t40 to time t41. The light source unit 21 is in a lighting state from time t41 to time t42. Note that the light source unit 21 is in a full lighting state from time t41 to time t42. Therefore, the brightness of the light source unit 21 does not change from time t41 to time t42.
　時刻ｔ４１から時刻ｔ４２の間、照明制御部２２は、光源ユニット２１からピンク色の光が出射されるように、光源ユニット２１を制御する。時刻ｔ４２において、照明制御部２２は、光源ユニット２１が消灯状態になるように、光源ユニット２１を制御する。時刻ｔ４２以後の光源ユニット２１の状態の遷移は、時刻ｔ４０から時刻ｔ４２までの光源ユニット２１の状態の遷移と同様である。 Between time t41 and time t42, the illumination control unit 22 controls the light source unit 21 so that pink light is emitted from the light source unit 21. At time t42, the illumination control section 22 controls the light source unit 21 so that the light source unit 21 is turned off. The state transition of the light source unit 21 after time t42 is the same as the state transition of the light source unit 21 from time t40 to time t42.
（官能試験）
　ところで、本実施例において光源ユニット２１がピンク色の光を出射するように構成した理由を説明する。発明者らは、運転手や歩行者等が温かい感情を抱きやすい光の色に関する官能試験を行った。当該官能試験の内容は、光源ユニット２１から出射される光について、その光の波長と、その光の色をｘｙ色度図におけるｘおよびｙで表現したときに、どのような波長およびｘ，ｙのときに人が温かい感情を抱きやすいかについて試験を行ったものである。 (sensory test)
Now, the reason why the light source unit 21 is configured to emit pink light in this embodiment will be described. The inventors conducted a sensory test on the color of light that makes drivers and pedestrians feel warm. The contents of the sensory test are the wavelength of the light emitted from the light source unit 21, and the wavelength and x, y when the color of the light is represented by x and y in the xy chromaticity diagram. This is a test to see if people tend to have warm feelings when
　当該官能試験の結果、波長５００ｎｍ以上で謝意を表す温かい感情を抱かせることが確認できた。また、例えば、ｘｙ色度図のｘが大きくなると赤みが強くなるが、当該官能試験の結果、ｘｙ色度図のｘが０．６より大きいと、人は警告の意味合いを強く感じることが分かった。一方で、ｘｙ色度図のｘが０．６以下であれば、人はそれほど強い感情がこもらない暖かみのある色と認識できることが確認できた。さらに、ｘｙ色度図でｘが０．６以下であれば、既存のブレーキランプやターンシグナルランプを点灯させる意図とは異なる意図であることを認識しやすいことも確認できた。以上の結果から、発明者らは、波長５００ｎｍ以上で、かつｘｙ色度図のｘが０．６以下である光であれば、交通参加者に対して確実に謝意を伝えることができることに気が付いた。 As a result of the sensory test, it was confirmed that a wavelength of 500 nm or more evokes a warm feeling of gratitude. Also, for example, redness increases as x in the xy chromaticity diagram increases, but as a result of the sensory test, it was found that when x in the xy chromaticity diagram is greater than 0.6, people strongly feel the meaning of a warning. rice field. On the other hand, it was confirmed that when x in the xy chromaticity diagram is 0.6 or less, people can recognize the color as a warm color that does not contain a very strong emotion. Furthermore, it was also confirmed that if x is 0.6 or less in the xy chromaticity diagram, it is easy to recognize that the intention is different from the intention to turn on the existing brake lamps and turn signal lamps. From the above results, the inventors realized that if the light has a wavelength of 500 nm or more and x is 0.6 or less in the xy chromaticity diagram, it is possible to reliably convey gratitude to traffic participants. rice field.
　上記構成に係る車両用コミュニケーションランプ２０によれば、ピンク色の光のスペクトルについての波長とその波長における光の強度に基づくピンク色の光の波長の平均値は５００ｎｍ以上であるため、謝意を表す温かい感情を交通参加者に抱かせる。また、上記構成に係る車両用コミュニケーションランプ２０によれば、ｘｙ色度図のｘが０．６以下であるため、暖かみのある色と交通参加者に認識させることもできる。さらに、ｘｙ色度図におけるｘは０．６以下であるため、車両用コミュニケーションランプ２０は、既存のブレーキランプやターンシグナルランプを点灯させる意図とは異なる意図であることを交通参加者に認識させることができる。このため、車両用コミュニケーションランプ２０によれば、謝意を確実に交通参加者に感得させることができる。 According to the vehicle communication lamp 20 having the above configuration, the average value of the wavelength of pink light based on the wavelength of the pink light spectrum and the light intensity at that wavelength is 500 nm or more. Bring warm feelings to traffic participants. In addition, according to the vehicle communication lamp 20 having the above configuration, since x in the xy chromaticity diagram is 0.6 or less, traffic participants can recognize the color as warm. Furthermore, since x in the xy chromaticity diagram is 0.6 or less, the vehicle communication lamp 20 makes traffic participants aware that the intention is different from lighting the existing brake lamps and turn signal lamps. be able to. Therefore, according to the vehicle communication lamp 20, it is possible to reliably make the traffic participants feel gratitude.
　また、上記構成に係る車両用コミュニケーションランプ２０によれば、光源ユニット２１は、交通参加者に謝意等の所定の情報を伝達するのに効果的な色であるピンク色の光を出射する。したがって、車両用コミュニケーションランプ２０によれば、謝意等の所定の情報を確実に交通参加者に感得させることができる。 Further, according to the vehicle communication lamp 20 having the above configuration, the light source unit 21 emits pink light, which is an effective color for conveying predetermined information such as gratitude to traffic participants. Therefore, according to the vehicle communication lamp 20, it is possible to reliably make the traffic participants feel the predetermined information such as gratitude.

Next, a sixth example of the first embodiment will be described with reference to FIG. In addition, in the present embodiment, the same reference numerals are given to the same configurations as those of the fifth embodiment of the first embodiment, and descriptions of overlapping descriptions are omitted as appropriate. This example is different from the fifth example of the first embodiment in that one cycle time is 2000 milliseconds and that the lighting state of the light source unit 21 changes. Also in this embodiment, the light source unit 21 emits pink light. Also in this embodiment, it is assumed that the user of vehicle 1 presses thank-you switch 4 at time t50 in order to express gratitude to traffic participants in the vicinity of vehicle 1 .
　図９に例示するように、時刻ｔ５０から時刻ｔ５１の間、光源ユニット２１は徐々に明るくなる。なお、時刻ｔ５０から時刻ｔ５１の間、光源ユニット２１に含まれる光源に流れる電流値の単位時間当たりの増加量は、時間が経過するにつれて徐々に大きくなる。 As illustrated in FIG. 9, the light source unit 21 gradually brightens from time t50 to time t51. Between time t50 and time t51, the amount of increase per unit time of the current flowing through the light source included in the light source unit 21 gradually increases as time elapses.
　時刻ｔ５１において、光源ユニット２１はフル点灯状態である。時刻ｔ５１から時刻ｔ５２の間、照明制御部２２は、光源ユニット２１が消灯状態になるように、光源ユニット２１を制御する。時刻ｔ５２以後の光源ユニット２１の状態の遷移は、時刻ｔ５０から時刻ｔ５２までの光源ユニット２１の状態の遷移と同様である。 At time t51, the light source unit 21 is in a full lighting state. Between time t51 and time t52, the illumination control section 22 controls the light source unit 21 so that the light source unit 21 is turned off. The state transition of the light source unit 21 after time t52 is the same as the state transition of the light source unit 21 from time t50 to time t52.
　本実施例においても、上記構成に係る車両用コミュニケーションランプ２０によれば、第一実施形態の第五実施例と同様の効果を奏することができる。 Also in this embodiment, according to the vehicle communication lamp 20 according to the above configuration, it is possible to obtain the same effects as in the fifth embodiment of the first embodiment.
（第二実施形態の第一実施例）
　次に、図１０から図１５を参照しつつ、第二実施形態の第一実施例について説明する。なお、本実施形態において、第一実施形態と同様の構成については同じ符号を付して説明し、説明が重複する部分については適宜説明を省略する。第二実施形態に係る車両用コミュニケーションランプ２０Ａは、光源ユニット２１の代わりに光源ユニット２１Ａ（図１１から図１５参照）を備えている点で、第一実施形態に係る車両用コミュニケーションランプ２０と異なる。図１１から図１５に例示するように、光源ユニット２１Ａは、４つの光源２１１Ａ～２１４Ａを含む。光源２１１Ａ～２１４Ａは、例えば、ＲＧＢ光源である。なお、本実施例において、光源２１１Ａ～２１４Ａからはアンバー色の光が出射される。したがって、光源ユニット２１Ａからはアンバー色の光が出射される。照明制御部２２は、点灯する光源の数が時間の経過に伴って増えるように、光源ユニット２１Ａを制御する。照明制御部２２は、光源ユニット２１Ａの明るさが経時的に変化するように、光源ユニット２１Ａを制御する。 (First Example of Second Embodiment)
Next, a first example of the second embodiment will be described with reference to FIGS. 10 to 15. FIG. In addition, in this embodiment, the same code|symbol is attached|subjected and demonstrated about the structure similar to 1st embodiment, and description is abbreviate|omitted suitably about the part which description overlaps. A vehicle communication lamp 20A according to the second embodiment differs from the vehicle communication lamp 20 according to the first embodiment in that a light source unit 21A (see FIGS. 11 to 15) is provided instead of the light source unit 21. . As illustrated in FIGS. 11-15, the light source unit 21A includes four light sources 211A-214A. Light sources 211A-214A are, for example, RGB light sources. In this embodiment, amber light is emitted from the light sources 211A to 214A. Therefore, amber light is emitted from the light source unit 21A. The lighting controller 22 controls the light source unit 21A so that the number of light sources that are turned on increases over time. The lighting controller 22 controls the light source unit 21A so that the brightness of the light source unit 21A changes over time.
　図１０に例示するグラフにおいて、横軸（図１０において左右方向に延びる軸）は時間を、縦軸（図１０において上下方向に延びる軸）は光源ユニット２１Ａの明るさを表している。なお、本実施例においても、車両１のユーザが、車両１の近傍にいる交通参加者に対して謝意を表意するために、時刻ｔ６０において、サンキュースイッチ４を押下したものとする。本実施形態においても、第一実施形態と同様に、車両１のユーザによってサンキュースイッチ４が押下されると、照明制御部２２は、受信した感情表出信号に基づいて、光源ユニット２１Ａを通常動作モードから感情表出モードに切り替える。なお、本実施例における一周期は、時刻ｔ６０から時刻ｔ６９までの時間である。時刻ｔ６０から時刻ｔ６９までの時間は、２０００ミリ秒である。 In the graph illustrated in FIG. 10, the horizontal axis (the axis extending horizontally in FIG. 10) represents time, and the vertical axis (the axis extending vertically in FIG. 10) represents the brightness of the light source unit 21A. Also in this embodiment, it is assumed that the user of vehicle 1 presses thank-you switch 4 at time t<b>60 in order to express gratitude to traffic participants near vehicle 1 . Also in this embodiment, similarly to the first embodiment, when the user of the vehicle 1 presses the thank-you switch 4, the lighting control section 22 normally operates the light source unit 21A based on the received emotional expression signal. Switch from mode to emotional expression mode. Note that one cycle in this embodiment is the time from time t60 to time t69. The time from time t60 to time t69 is 2000 milliseconds.
　次に、図１０から図１５を参照しつつ、光源ユニット２１Ａの点灯状態の遷移について説明する。図１０に例示するように、照明制御部２２は、光源ユニット２１Ａから出射される光が、時間が経過するにつれて段階的に明るくなるように、光源ユニット２１Ａを制御する。なお、本実施例において、光源ユニット２１Ａから出射される光は、段階的に明るくなり続ける。光源ユニット２１Ａの明るさは、光源ユニット２１Ａの明るさが変化しない状態と、光源ユニット２１Ａの明るさが変化する状態と、が、交互に繰り返されながら、段階的に変化する。なお、本実施例において、約４００ミリ秒経過するごとに光源ユニット２１Ａに流れる電流値は増加する。ただし、光源ユニット２１Ａに流れる電流値が増加してから次に光源ユニット２１Ａに流れる電流値が増加するまでの時間間隔は約４００ミリ秒に限られない。例えば、約３３３ミリ秒経過するごとに光源ユニット２１Ａに流れる電流値は増加してもよい。この場合、光源ユニット２１Ａは、５つの光源を含む。また、本実施例において、光源ユニット２１Ａに流れる電流値の増加量は一定であるが、一定でなくてもよい。 Next, the transition of the lighting state of the light source unit 21A will be described with reference to FIGS. 10 to 15. FIG. As illustrated in FIG. 10, the illumination control section 22 controls the light source unit 21A so that the light emitted from the light source unit 21A becomes brighter step by step over time. In addition, in this embodiment, the light emitted from the light source unit 21A continues to become brighter step by step. The brightness of the light source unit 21A changes stepwise while alternately repeating a state in which the brightness of the light source unit 21A does not change and a state in which the brightness of the light source unit 21A changes. In this embodiment, the current value flowing through the light source unit 21A increases every time about 400 milliseconds elapse. However, the time interval from when the current value flowing through the light source unit 21A increases to when the current value flowing through the light source unit 21A next increases is not limited to approximately 400 milliseconds. For example, the current value flowing through the light source unit 21A may increase every time about 333 milliseconds elapse. In this case, the light source unit 21A includes five light sources. Also, in this embodiment, the amount of increase in the value of the current flowing through the light source unit 21A is constant, but it does not have to be constant.

Therefore, the lighting state of the light source unit 21A is the state illustrated in FIG. 13 from time t63 to time t65.
　図１０に例示するように、時刻ｔ６３から時刻ｔ６４の間、照明制御部２２は、光源ユニット２１Ａから出射される光が、時間が経過するにつれて段階的に明るくなるように、光源ユニット２１Ａを制御する。また、時刻ｔ６４から時刻ｔ６５の間、照明制御部２２は、光源ユニット２１Ａから出射される光の明るさが変化しないように、光源ユニット２１Ａを制御する。 As illustrated in FIG. 10, between time t63 and time t64, the illumination control unit 22 controls the light source unit 21A so that the light emitted from the light source unit 21A becomes brighter in stages as time passes. do. Further, from time t64 to time t65, the illumination control section 22 controls the light source unit 21A so that the brightness of the light emitted from the light source unit 21A does not change.

　次に、図１６を参照しつつ、第二実施形態の第二実施例について説明する。なお、本実施例において、第二実施形態の第一実施例と同様の構成については同じ符号を付して説明し、説明が重複する部分については適宜説明を省略する。本実施例は、光源ユニット２１Ａから出射される光の色が緑色（黄緑色）である点と、一周期の時間が１０００ミリ秒である点と、光源ユニット２１Ａの点灯状態の変化の様子が異なる点と、で、第二実施形態の第一実施例と異なる。なお、本実施例において、光源ユニット２１Ａは、一つ以上の光源を含むものとする。当該光源は、例えば、ＲＧＢ光源である。また、本実施例においても、車両１のユーザが、車両１の近傍にいる交通参加者に対して謝意を表意するために、時刻ｔ７０において、サンキュースイッチ４を押下したものとする。 (Second example of the second embodiment)
Next, a second example of the second embodiment will be described with reference to FIG. In addition, in the present embodiment, the same reference numerals are assigned to the same configurations as those of the first embodiment of the second embodiment, and the descriptions of overlapping descriptions are omitted as appropriate. In this embodiment, the color of the light emitted from the light source unit 21A is green (yellow-green), the time of one cycle is 1000 milliseconds, and the lighting state of the light source unit 21A changes. It differs from the first example of the second embodiment in different points. In addition, in this embodiment, the light source unit 21A shall include one or more light sources.

Between time t70 and time t71, the illumination control unit 22 controls the light source unit 21A so that the green light and the red light included in the light emitted from the light source unit 21A gradually become brighter as time passes. to control. The amount of increase per unit time in the brightness of the green light included in the light emitted from the light source unit 21A is the amount per unit time of the brightness of the red light included in the light emitted from the light source unit 21A. greater than the increment. Therefore, the color of the light emitted from the light source unit 21A is green (yellow green) from time t70 to time t71. At time t71, the light source unit 21A is in a full lighting state. Therefore, the time required for the light source unit 21A to transition from the off state to the full lighting state in the emotion expression mode is 500 milliseconds.
　時刻ｔ７１から時刻ｔ７２の間、照明制御部２２は、光源ユニット２１Ａから出射される光に含まれる緑色の光および赤色の光が、時間が経過するにつれて共に徐々に暗くなるように、光源ユニット２１Ａを制御する。光源ユニット２１Ａから出射される光に含まれる緑色の光の明るさの単位時間当たりの減少量は、光源ユニット２１Ａから出射される光に含まれる赤色の光の明るさの単位時間当たりの減少量よりも大きい。時刻ｔ７１から時刻ｔ７２の間、光源ユニット２１Ａから出射される光の色は、緑色（黄緑色）である。 Between time t71 and time t72, the illumination control unit 22 controls the light source unit 21A so that both the green light and the red light included in the light emitted from the light source unit 21A gradually darken as time passes. to control.

The state transition of the light source unit 21A after time t72 is the same as the state transition of the light source unit 21A from time t70 to time t72.
　本実施例においても、上記構成に係る車両用コミュニケーションランプ２０Ａによれば、第二実施形態の第一実施例と同様の効果を奏することができる。 Also in this embodiment, according to the vehicle communication lamp 20A having the above configuration, it is possible to achieve the same effects as in the first embodiment of the second embodiment.

For example, the first light source that emits the first light (the light source 210 drawn by the solid line in FIG. 3) and the second and a second light source (light source 211 drawn with a dashed line in FIG. 3) that emits a second light of a color different from the color of the first light. In this case, the illumination control unit 22 controls the light source unit 21 so as to change the brightness of at least one of the first light source (light source 210) and the second light source (light source 211) over time.

However, the present disclosure is not limited to this. For example, the time required for the light source unit 21A to transition from the fully lit state to the extinguished state in the normal operation mode is shorter than the time required for the light source unit 21A to transition from the fully lit state to the extinguished state in the emotion expression mode. may Even in this case, the transition of the lighting state in the emotional expression mode appears to the traffic participant to be more gradual than the transition of the lighting state in the normal operation mode.
