The present invention relates to a vehicle door open notification illumination device suitable for alerting a third party.

自動車等の車輌の安全性を向上するために、後方の他の自動車等の車輌の接近あるいは進路変更に伴う前方の車輌の接近をレーザセンサ等により検知して、自車輌の車室内の照明装置を点灯又は点滅して運転者等に知らせる接近報知装置が提案されている（特許文献１）。接近報知装置に用いる車室内の照明装置には、ルームランプ、読書ランプ、フロントドアカーテシランプ、フロント足元ランプ、等が提案されている。これによれば、自車輌の運転者等に注意を促して安全性を向上できる。しかし、同文献には、外開きドアを開くときに後方の自転車等の軽車輌を含む車輌や歩行者等の第三者に報知することは配慮されていない。   In order to improve the safety of a vehicle such as an automobile, an illumination device for the interior of the vehicle of the own vehicle is detected by detecting, for example, a laser sensor or the like when a vehicle such as another automobile behind is approaching or approaching a vehicle when the route is changed. An approach notification device has been proposed that informs a driver or the like by lighting or blinking (Patent Document 1). Room lamps, reading lamps, front door courtesy lamps, front foot lamps, and the like have been proposed as lighting devices in the vehicle interior used for the approach notification device. According to this, safety can be improved by alerting the driver or the like of the own vehicle. However, this document does not consider notifying a third person such as a vehicle or a pedestrian including a rear light vehicle such as a bicycle when the outside door is opened.

一方、外開きドアを開くことを後方の車輌に知らせるために、ドアの後側面、つまりドアの厚み部分の高さ方向に複数の発光素子を並べて設け、複数の発光素子を点滅制御することにより、残像効果を利用してドアの開く方向を示す矢印などの図案を発光表示させることが提案されている（特許文献２）。これによれば、後方車輌に報知して注意を促すことができる。また、特許文献３には、後方車輌に報知して注意を促すために、ドアの後側面にＬＥＤランプを埋め込んで、ドアを開けた際にＬＥＤランプを点灯させることが提案されている。   On the other hand, in order to notify the vehicle behind the door that the door is opened, a plurality of light emitting elements are arranged side by side in the height direction of the rear side of the door, that is, the thickness portion of the door, and the plurality of light emitting elements are controlled to blink. In addition, it has been proposed to emit and display a design such as an arrow indicating the door opening direction using the afterimage effect (Patent Document 2). According to this, it is possible to alert the rear vehicle and call attention. Patent Document 3 proposes that an LED lamp is embedded in the rear side surface of a door and the LED lamp is turned on when the door is opened in order to notify the rear vehicle and call attention.

しかし、特許文献１〜３は、いずれも外開きドアを開く搭乗者に注意を促すこと、つまり外開きドアを開くときに、搭乗者に対して後方の車輌又は歩行者等に注意して開くことを報知することについては考慮されていない。   However, all of Patent Documents 1 to 3 call attention to the passenger who opens the outer opening door, that is, when opening the outer opening door, open the attention of the vehicle or pedestrian behind the passenger. This is not considered.

本発明が解決しようとする課題は、搭乗者が外開きドアを開く際に、後方の車輌又は歩行者等に注意を促すのに好適な車輌ドア開報知照明装置を提供することにある。   SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle door open notification illumination device suitable for alerting a vehicle or a pedestrian behind when a passenger opens an exterior door.

上記の課題を解決するため、本発明の車輌ドア開報知照明装置は、車輌の外開きドアの車室側の内面からドア後部の側面にわたって設けられた発光部と、該発光部を異なる発光モードで発光させる制御部とを備えて構成する。そして、前記制御部は、前記車輌の搭乗者が前記外開きドアのドアノブに接触したことを検知したドアノブ接触検知信号と、前記外開きドアが開かれたことを検知するドア開検知信号と、自車輌の後方に車輌又は歩行者が接近したことを感知する後方車等接近検知信号とを順に入力し、前記ドアノブ接触検知信号がオンで、前記ドア開検知信号がオフのときは、前記発光部を第１の発光モードで発光させ、前記ドアノブ接触検知信号がオンで、前記ドア開検知信号がオン、前記後方車等接近検知信号がオフのときは、前記発光部を第２の発光モードで発光させ、前記ドアノブ接触検知信号がオンで、前記ドア開検知信号がオン、前記後方車等接近検知信号がオンのときは、前記発光部を第３の発光モードで発光させることを特徴とする。また、ドア開検知信号と後方車等接近検知信号の入力順を入れ替えて、同様に発光モードを制御するようにしてもよい。 In order to solve the above-described problems, a vehicle door open notification illumination device according to the present invention includes a light emitting portion provided from an inner surface of a vehicle exterior side of a vehicle to a side surface of a rear portion of the door, and a different light emission mode. And a control unit that emits light. And the said control part, the door knob detection signal which detected that the passenger of the said vehicle contacted the door knob of the said outside door, the door opening detection signal which detects that the said outside door was opened, a rear wheel such approach detecting signal for sensing that the vehicle or pedestrian behind the own vehicle has approached sequentially enter, the door knob contact detection signal is on, when pre-Symbol door open detection signal is off, the a light emitting portion to emit light in a first emission mode, in the doorknob contact detection signal is turned on, before Symbol door opening detection signal is turned on, when such approach detecting signal the rear wheel is off, the light emitting portion second When the door knob contact detection signal is on, the door open detection signal is on, and the approach detection signal for the rear vehicle is on, the light emitting unit is caused to emit light in the third light emission mode. It is characterized by. Alternatively, the light emission mode may be controlled in the same manner by switching the input order of the door open detection signal and the approach detection signal for the rear vehicle.

本発明によれば、ドア開の検知信号と後方車等接近検知信号の一方の検知信号をトリガ信号として、搭乗者が外開きドアを開こうとしたとき、又は開き始めたときに、外開きドアの車室側の内面に設けられた発光部が発光するから、車室内にいる搭乗者の注意を喚起することができる。その結果、搭乗者がドアを開こうとしてドアノブに接触したときに、後方の車輌又は歩行者等に注意すべきであることを思い出して、ドアの開け方を加減することができ、自動車等の車輌や歩行者の安全性を向上することができる。 According to the present invention, the detection signal of the hand of the door opening detection signal and the rear wheel such approach detecting signal as a trigger signal, when the occupant when attempting to open the outer opening doors, or begins to open, the outer Since the light emitting portion provided on the inner surface of the hinged door on the passenger compartment side emits light, it is possible to alert the passenger in the passenger compartment. As a result, when the passenger touches the door knob in an attempt to open the door, he / she should be aware of the vehicle or pedestrian behind him, so he can adjust how to open the door. The safety of vehicles and pedestrians can be improved.

つまり、搭乗者がドアを開く前に、ドアノブに触れただけで車室側の内面に設けられた発光部が発光するから、搭乗者は余裕を持って後方の車輌又は歩行者等に注意しなければならないことに気付き、ドアの開閉を的確に操作することができ、自動車等の車輌や歩行者の安全性を向上することができる。 In other words, before the tower ride you open the door, since the light emitting portion just touches the door knob provided on an inner surface of the cabin side emits light, the rider or the like behind the vehicle or pedestrian with extra Yutaka realized that care must be taken, the opening and closing of the door can be operated accurately, Ru can be used to improve vehicle and pedestrian safety, such as an automobile.

前記発光部は、一端が発光素子に連結された棒状又は帯状の導光体で形成すること、又は複数の発光素子を直状に配列して形成することができる。これによれば、ドアの車室側の内面に伸延して設けられた棒状又は帯状あるいは直状の発光部が発光するので、注意喚起効果を一層向上できる。   The light emitting part may be formed of a rod-shaped or belt-shaped light guide having one end connected to the light emitting element, or may be formed by arranging a plurality of light emitting elements in a straight line. According to this, since the bar-shaped or belt-shaped or straight light-emitting portion provided to extend on the inner surface of the door on the passenger compartment side emits light, the alerting effect can be further improved.

さらに、本発明において、発光部の発光モードは、発光部の色、点滅、点滅スピード、及びこれらの組合せにより、注意喚起力を異ならせることができる。例えば、発光部の色を分け、「赤」は「注意喚起」、「青又は白」は「軽注意喚起」とし、「赤の点滅」は「重注意喚起」等に区別することができる。さらに、後方車輌の接近速度又は距離に応じて「赤の点滅」の点滅スピードを速くすることにより、搭乗者にさらに強い「重注意喚起」を促すことができる。   Furthermore, in the present invention, the light emission mode of the light emitting unit can vary the alerting power according to the color of the light emitting unit, the blinking, the blinking speed, and a combination thereof. For example, the colors of the light-emitting portions can be divided, and “red” can be classified as “warning”, “blue or white” as “light alert”, and “red flashing” as “heavy alert”. Furthermore, by increasing the flashing speed of “red flashing” in accordance with the approaching speed or distance of the rear vehicle, it is possible to prompt the passenger to further “heavy attention”.

なお、シートベルトと連動させて、搭乗者が乗車している側の外開きドアの発光部のみを発光させるようにすることができる。   It is to be noted that, in conjunction with the seat belt, only the light emitting part of the outer opening door on the side on which the passenger is on can be made to emit light.

本発明によれば、搭乗者が外開きドアを開く際に、後方の車輌又は歩行者等に注意を促すのに好適な車輌ドア開報知照明装置を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, when a passenger opens an outward opening door, the vehicle door opening alerting | reporting illuminating device suitable for alerting a vehicle or a pedestrian behind, etc. can be provided.

以下、本発明を実施形態に基づいて説明する。   Hereinafter, the present invention will be described based on embodiments.

本発明の一実施形態の車輌ドア開報知照明装置１０は、自動車１の左右前後の外開きドアに設けられるが、図示及び説明を簡単にするために、図１（ａ）に示すように、進行方向右側の外開きドア２に取り付けられた車輌ドア開報知照明装置１０を例に説明する。図において、外開きドア（以下、適宜、ドアと略す。）２は開かれた状態が示されている。車輌ドア開報知照明装置１０は、同図（ｂ）に示すように、棒状又は帯状の発光部である導光体１１と、導光体１１の前側の一端に接続された光接続部１２と、光接続部１２に光結合された発光素子であるＬＥＤユニット１３を有して形成されている。   The vehicle door open notification illumination device 10 according to an embodiment of the present invention is provided at the left and right front doors of the automobile 1. However, in order to simplify the illustration and description, as shown in FIG. The vehicle door opening notification illumination device 10 attached to the outer opening door 2 on the right side in the traveling direction will be described as an example. In the figure, an open door (hereinafter, abbreviated as a door as appropriate) 2 is shown in an opened state. As shown in FIG. 2B, the vehicle door open notification illumination device 10 includes a light guide 11 that is a rod-shaped or belt-shaped light emitting portion, and an optical connection portion 12 that is connected to one end on the front side of the light guide 11. The LED unit 13 is a light emitting element optically coupled to the optical connecting portion 12.

導光体１１は、ＬＥＤユニット１３から出射される光を一端から他端まで効率よく導くように形成されている。また、導光体１１は、ドア２の車室内側の内面に前側から後側にまで伸延され、ドア２の後側の側面である厚み部分３に折り曲げ形成された他端部１１ａを備えている。ＬＥＤユニット１３は、図２に示すように、赤（ＲＥＤ）、緑（ＧＲＥＥＮ）、青（ＢＬＵＥ）の３色のＬＥＤ１３ａ，ｂ，ｃと、各ＬＥＤ１３ａ，ｂ，ｃに並列接続されたツェナーダイオード１４ａ，ｂ，ｃと、各ＬＥＤ１３ａ，ｂ，ｃに直列接続された抵抗１５ａ，ｂ，ｃを備えて形成されている。このように構成されたＬＥＤユニット１３は、制御部であるサブＥＣＵ（electronic Control Unit）１６によって、発光色、点灯、消灯、点滅を制御可能に形成されている。すなわち、各ＬＥＤ１３ａ，ｂ，ｃのアノードは、サブＥＣＵ１６の電源＋Ｂに接続されている。各ＬＥＤ１３ａ，ｂ，ｃのカソードは、各抵抗１５ａ，ｂ，ｃを介して点灯信号がそれぞれ供給されている。サブＥＣＵ１６は、マイコンなどの演算処理装置、電源及びメモリ等を備えて形成されている。また、サブＥＣＵ１６は、上位のメインＥＣＵ１７から各種情報（例えば、後述するトリガ信号）が入力されるようになっている。   The light guide 11 is formed so as to efficiently guide the light emitted from the LED unit 13 from one end to the other end. In addition, the light guide 11 includes an other end portion 11 a that extends from the front side to the rear side on the inner surface of the door 2 on the vehicle interior side and is bent at a thickness portion 3 that is a rear side surface of the door 2. Yes. As shown in FIG. 2, the LED unit 13 includes red (RED), green (GREEN), and blue (BLUE) LEDs 13a, b, and c, and a Zener diode connected in parallel to the LEDs 13a, b, and c. 14a, b, c and resistors 15a, b, c connected in series to the LEDs 13a, b, c. The LED unit 13 configured as described above is formed so that the emission color, lighting, extinguishing, and blinking can be controlled by a sub ECU (electronic control unit) 16 that is a control unit. That is, the anode of each LED 13a, b, c is connected to the power source + B of the sub ECU 16. Lighting signals are supplied to the cathodes of the LEDs 13a, b, and c via the resistors 15a, b, and c, respectively. The sub ECU 16 includes an arithmetic processing unit such as a microcomputer, a power source, a memory, and the like. Further, the sub ECU 16 receives various information (for example, a trigger signal described later) from the upper main ECU 17.

トリガ信号は、ＬＥＤユニット１３を点灯させるきっかけとなる信号である。本実施形態のトリガ信号は、外開きドア２が開かれたことを検知する図示していないドア開閉検知装置から出力されるドア開検知信号と、自車輌の後方に車輌又は歩行者が接近したことを感知する図示していない後方感知装置から出力される後方車等接近検知信号と、搭乗者が外開きドア２のドアノブに接触したことを検知する図示していないドアノブ接触検知装置から出力されるドアノブ接触検知信号、及びイグニッションキーがオン状態にあることを検知するイグニッション検知信号が含まれている。また、サブＥＣＵ１６は、メインＥＣＵ１７から入力されるトリガ信号の組合せにより、予め設定された発光モードでＬＥＤユニット１３を点灯、点滅、消灯するとともに、発光色を制御するようになっている。   The trigger signal is a signal that triggers the LED unit 13 to light up. The trigger signal of the present embodiment includes a door opening detection signal output from a door opening / closing detection device (not shown) that detects that the outer opening door 2 has been opened, and a vehicle or pedestrian has approached behind the vehicle. A rear vehicle approach detection signal output from a rear sensing device (not shown) that senses this, and a door knob contact detection device (not shown) that detects that the passenger has touched the door knob of the outer door 2. A door knob contact detection signal and an ignition detection signal for detecting that the ignition key is in an ON state. Further, the sub ECU 16 turns on, blinks, and turns off the LED unit 13 in a preset light emission mode and controls the light emission color by a combination of trigger signals input from the main ECU 17.

次に、ＬＥＤユニット１３を制御するサブＥＣＵ１６の具体的な制御例を実施例に分けて説明する。実施例１〜３は、マルチカラーＬＥＤを備えた実施形態１のトリガ信号の組合せに基づいて、予め設定された発光モードによりＬＥＤユニット１３を制御する例である。   Next, a specific control example of the sub ECU 16 that controls the LED unit 13 will be described by dividing it into embodiments. Examples 1 to 3 are examples in which the LED unit 13 is controlled by a preset light emission mode based on the combination of trigger signals of the first embodiment provided with multi-color LEDs.

（実施例１）
実施例１の発光モード制御のフローチャートを図３Ａに示す。サブＥＣＵ１６の発光モード制御をスタートすると、入力されるイグニッション信号ＩＧがオンか否か判断し（Ｓ１）、オンであればドアノブ接触検知信号がオンか否か判断する（Ｓ２）。ドアノブ接触検知信号がオフであれば、予め設定された通常のイルミ（イルミネーション：電飾）によりＬＥＤユニット１３を発光させる（Ｓ３）。通常のイルミとは、例えば、電飾を目的としてＬＥＤユニット１３を発光させるモードであり、注意喚起とは異なる発光モードである。ドアノブ接触検知信号がオンのときは、後方車等接近検知信号がオンか否か判断する（Ｓ４）。後方車等接近検知信号がオフであれば、比較的安全であるから、ＬＥＤユニット１３を「青色」又は「白色」の軽注意喚起モードで発光させる（Ｓ５）。これにより、搭乗者は、後方の安全を十分に確認する必要はあるが、ドア２を開いても安全である。 Example 1
The flowchart of the light emission mode control of Example 1 is shown to FIG. 3A. When the light emission mode control of the sub ECU 16 is started, it is determined whether or not the input ignition signal IG is on (S1). If it is on, it is determined whether or not the doorknob contact detection signal is on (S2). If the doorknob contact detection signal is off, the LED unit 13 is caused to emit light by a preset normal illumination (illumination: electrical decoration) (S3). The normal illumination is, for example, a mode in which the LED unit 13 emits light for the purpose of electrical decoration, and is a light emission mode that is different from alerting. When the doorknob contact detection signal is on, it is determined whether the approach detection signal for the rear vehicle etc. is on (S4). If the approach detection signal such as the rear vehicle is off, it is relatively safe, and the LED unit 13 is caused to emit light in the “blue” or “white” light alert mode (S5). Thereby, although a passenger needs to fully confirm the safety of the back, even if the door 2 is opened, it is safe.

一方、後方車等接近検知信号がオンであれば、ドア開検知信号がオンか否かを判断する（Ｓ６）。ドア開検知信号がオフの場合は、搭乗者がドアを開く場合の注意を喚起するために、ＬＥＤユニット１３を「赤色」の注意喚起モードで発光させる（Ｓ７）。このとき、ドア開検知信号がオンであれば、すなわち、搭乗者がドアを開き始めた場合は、十分な注意を喚起するために、ＬＥＤユニット１３を「赤色」で点滅させる重注意喚起モードで発光させる（Ｓ８）。   On the other hand, if the approach detection signal such as the rear vehicle is on, it is determined whether or not the door open detection signal is on (S6). If the door open detection signal is off, the LED unit 13 is caused to emit light in the “red” alert mode in order to call attention when the passenger opens the door (S7). At this time, if the door open detection signal is on, that is, if the occupant starts to open the door, the LED unit 13 blinks in “red” in order to alert the user sufficiently. Light is emitted (S8).

（実施例２）
実施例２の発光モード制御は、図３Ｂのフローチャートに示すように、実施例１と相違する点は、実施例１のＳ４、Ｓ６とを入れ替えたことにあり、Ｓ６をＳ１４，Ｓ４をＳ１６としている。その他のステップは、実施例１と同一であることから、同一の符号を付して説明を省略する。 (Example 2)
As shown in the flowchart of FIG. 3B, the light emission mode control of the second embodiment is different from the first embodiment in that S4 and S6 of the first embodiment are replaced, and S6 is changed to S14 and S4 is changed to S16. Yes. Since the other steps are the same as those in the first embodiment, the same reference numerals are given and description thereof is omitted.

（実施例３）
実施例３の発光モード制御は、図３Ｃのフローチャートに示すように、実施例２のフローチャートにおけるステップＳ２を省略したことが相違する。そして、ドア開検知信号がオンか否かを判断して（Ｓ１４）、ドア開検知信号がオフの場合は、通常イルミ（イルミネーション：電飾）によりＬＥＤユニット１３を発光させる（Ｓ３）ことが相違する。その他の点は、実施例２と同一であることから、同一の符号を付して説明を省略する。 (Example 3)
The light emission mode control of the third embodiment is different from the flow chart of FIG. 3C in that step S2 in the flowchart of the second embodiment is omitted. Then, it is determined whether or not the door open detection signal is on (S14). If the door open detection signal is off, the LED unit 13 is caused to emit light by normal illumination (illumination: electrical decoration) (S3). To do. Since the other points are the same as those of the second embodiment, the same reference numerals are given and description thereof is omitted.

以上説明したように、本実施形態１のいずれの実施例においても、ドア開検知信号と後方車等接近検知信号の少なくとも一方の検知信号をトリガ信号として、搭乗者がドア２を開こうとしたとき、又は開き始めたときに、ドア２の車室側の内面に設けられた導光体１１が発光するから、搭乗者の注意を喚起することができる。その結果、本実施形態１によれば、搭乗者がドア２を開くときに、後方の車輌又は歩行者等に注意しなければならないことを思い出して、ドア２の開け方を加減することができ、自動車等の車輌や歩行者の安全性を向上することができる。   As described above, in any example of the first embodiment, the passenger tries to open the door 2 using the detection signal of at least one of the door opening detection signal and the approach detection signal of the rear vehicle as a trigger signal. When or when it begins to open, the light guide 11 provided on the inner surface of the door 2 on the passenger compartment side emits light, so that the passenger's attention can be alerted. As a result, according to the first embodiment, when the passenger opens the door 2, it is possible to adjust the opening of the door 2 by remembering that a passenger or a pedestrian or the like must be careful. In addition, the safety of vehicles such as automobiles and pedestrians can be improved.

また、実施例１，２によれば、車輌の搭乗者がドア２のドアノブに接触したことを検知した検知信号が入力されたとき、導光体１１を第３の発光モードの「青」又は「白」で発光させるから、搭乗者がドアノブに触れただけで導光体１１が発光する。その結果、搭乗者は一層余裕を持って後方の車輌又は歩行者等に注意しなければならないことに気付き、自動車等の車輌や歩行者の安全性を向上することができる。   Further, according to the first and second embodiments, when the detection signal that detects that the vehicle occupant has touched the door knob of the door 2 is input, the light guide 11 is set to “blue” in the third light emission mode or Since light is emitted in “white”, the light guide 11 emits light only when the passenger touches the door knob. As a result, the passenger notices that he / she must pay more attention to the vehicle or pedestrian behind, and the safety of vehicles such as automobiles and pedestrians can be improved.

なお、本実施形態１では、発光部を一端が発光素子に連結された棒状又は帯状の導光体１１で形成する例を示したが、本発明はこれに限られるものではなく、例えば複数のＬＥＤ等の発光素子を直状に配列して形成することができる。いずれにしても、ドア２の車室側の内面に設けられた棒状又は帯状あるいは直状の発光部が発光するので、注意喚起効果を一層向上できる。   In the first embodiment, the example in which the light-emitting portion is formed by the rod-shaped or strip-shaped light guide body 11 having one end connected to the light-emitting element has been described. Light emitting elements such as LEDs can be arranged in a straight line. In any case, since the bar-shaped, belt-shaped or straight light-emitting portion provided on the inner surface of the door 2 on the passenger compartment side emits light, the alerting effect can be further improved.

さらに、本実施形態の実施例１，２において、ＬＥＤユニット１３に光結合された導光体１１の発光モードを、色、点滅、点滅スピード、及びこれらの組合せにより異ならせたことから、注意喚起の重要度に応じて使い分けすることができる。例えば、発光部の色を分け、「赤」は「注意喚起」、「青又は白」は「軽注意喚起」とし、「赤の点滅」は「重注意喚起」等に区別することができる。さらに、後方車輌の接近速度又は距離に応じて「赤の点滅」の点滅スピードを速くするようにすれば、搭乗者に対してさらに強い「重注意喚起」を促すことができる。   Further, in Examples 1 and 2 of the present embodiment, the light emission mode of the light guide 11 optically coupled to the LED unit 13 is changed depending on the color, blinking, blinking speed, and combinations thereof. It can be used properly according to the importance of. For example, the colors of the light-emitting portions can be divided, and “red” can be classified as “warning”, “blue or white” as “light alert”, and “red flashing” as “heavy alert”. Furthermore, if the blinking speed of “red blinking” is increased according to the approaching speed or distance of the rear vehicle, it is possible to urge the passenger to further “heavy attention”.

次に、実施形態１のＬＥＤユニット１３を単色（赤色）のＬＥＤに変えた場合のサブＥＣＵ１６の具体的な発光モード制御例を実施例４〜６に分けて説明する。実施例４〜６は、実施形態１と同様のトリガ信号の組合せに基づいて、予め設定されたトリガ信号の組合せに応じた発光モードにより赤色ＬＥＤを制御する例である。   Next, a specific light emission mode control example of the sub ECU 16 when the LED unit 13 of the first embodiment is changed to a single color (red) LED will be described in Examples 4 to 6. Examples 4 to 6 are examples in which the red LED is controlled by a light emission mode corresponding to a preset combination of trigger signals based on the same combination of trigger signals as in the first embodiment.

（実施例４）
実施例４は、図４Ａのフローチャートに示すように、実施例１の発光モードを「赤」と「赤の点滅」を使い分けるようにした点が異なるだけであり、その他の点は、実施例１と同一であることから、説明を省略する。 Example 4
As shown in the flowchart of FIG. 4A, the fourth embodiment is different from the first embodiment in that the light emission mode of the first embodiment is differently used for “red” and “red blinking”. The description is omitted because it is the same.

（実施例５）
実施例５は、図４Ｂのフローチャートに示すように、実施例２の発光モードを「赤」と「赤の点滅」を使い分けるようにした点が異なるだけであり、その他の点は、実施例２と同一であることから、説明を省略する。 (Example 5)
As shown in the flowchart of FIG. 4B, the fifth embodiment is different from the second embodiment in that the light emission mode of the second embodiment is selectively used as “red” and “red blinking”. The description is omitted because it is the same.

（実施例６）
実施例６は、図４Ｃのフローチャートに示すように、実施例３の発光モードを「赤」と「赤の点滅」を使い分けるようにした点が異なる。また、他の実施例1〜５とは異なり、ＩＧ検知信号がオフのときでも通常イルミモードで発光させるようにしている。その他の点は、実施例３と同一であることから、説明を省略する。 (Example 6)
As shown in the flowchart of FIG. 4C, the sixth embodiment is different from the third embodiment in that the red light mode and the “flashing red” are used separately. Also, unlike the other examples 1 to 5, the light is emitted in the normal illumination mode even when the IG detection signal is off. Since the other points are the same as those of the third embodiment, description thereof is omitted.

以上、本発明を一実施形態及び実施例に基づいて説明したが、本発明はこれらに限定されるものではなく、本発明の主旨の範囲で変形又は変更された形態で実施することが可能であることは、当業者にあっては明白なことであり、そのような変形又は変更された形態が本願の特許請求の範囲に属することは当然のことである。例えば、シートベルトと連動させて、搭乗者が乗車している側の外開きドア２の導光体１１のみを発光させるようにすることができる。   As mentioned above, although this invention was demonstrated based on one Embodiment and an Example, this invention is not limited to these, It is possible to implement in the form changed or changed in the range of the main point of this invention. Certainly, it will be obvious to those skilled in the art, and such variations or modifications are naturally within the scope of the claims of this application. For example, in conjunction with the seat belt, only the light guide 11 of the outer opening door 2 on the side on which the passenger is on can be caused to emit light.
