前記緊急車両は、
前記照明制御信号を送信又は受信するように構成された第2無線通信部と、
光を照射するように構成された表示部と、
前記表示部の照明状態を制御するように構成された制御部と、を備える。
A)前記第1無線通信部が前記第2無線通信部から前記照明制御信号を受信したとき、前記照明制御部は、前記受信した照明制御信号に基づいて、前記第2照明ユニットの照明状態が前記表示部の照明状態と対応するように前記第2照明ユニットを制御し、または、

以下、第1実施形態について図面を参照しながら説明する。尚、本実施形態の説明において既に説明された部材と同一の参照番号を有する部材については、説明の便宜上、その説明は省略する。また、本図面に示された各部材の寸法は、説明の便宜上、実際の各部材の寸法とは異なる場合がある。
最初に、車両制御部3は、車両1の運転モードが自動運転モードであるかどうかを判断する(ステップS10)。車両制御部3は、車両1の運転モードが自動運転モードであると判断したとき(ステップS10でYES)、車両制御部3は、車両1を停止させるべきかどうかを判断する(ステップS11)。一方、車両制御部3は、車両1の運転モードが自動運転モードでない(即ち、手動運転モードである)と判断したとき(ステップS10でNO)、車両1の運転モードが自動運転モードになるまで待機する。
次に、照明ユニットの第1変形例について以下に説明する。
先に述べた実施形態では、照明ユニット42(左側照明ユニット42L、右側照明ユニット42R)は、レーザ光の走査により形成された停止予告情報(停止線M1、横断歩道M2)を路面R上に表示するように構成されている。
一方、本変形例では、照明ユニット42(左側照明ユニット42L、右側照明ユニット42R)は、車両1の前方に向けて光を照射するように構成されていると共に、照明制御部43は、照明ユニット42の照明状態(点消灯、照明色、発光領域、点滅周期、発光強度等)を所定の照明状態に設定するように構成されている。照明ユニット42は、1以上のLED(Light Emitting Diode)やレーザ等の発光素子を含む。照明制御部43は、車両制御部3から受信した指示信号に基づいて、照明ユニット42の照明状態を所定の照明状態に設定する。具体的には、照明制御部43は、指示信号に基づいて照明ユニット42を点灯又は消灯するように構成されてもよい。例えば、照明ユニット42が初期状態において消灯している場合、照明制御部43は、指示信号に基づいて、照明ユニット42を点灯させてもよい。これとは反対に、照明ユニット42が初期状態において点灯している場合、照明制御部43は、指示信号に基づいて、照明ユニット42を消灯させてもよい。または、照明制御部43は、指示信号に基づいて照明ユニット42の照明色を所定の照明色(例えば、白色、緑色、青色等)に設定してもよい。さらに、照明制御部43は、指示信号に基づいて照明ユニット42の発光領域を所定の発光領域に設定してもよい(例えば、照明ユニット42の体積の半分が発光領域として設定される等)。さらに、照明制御部43は、指示信号に基づいて照明ユニット42の点滅周期を所定の点滅周期Tに設定してもよい。例えば、照明ユニット42が初期状態において点滅していない場合、照明制御部43は、指示信号に基づいて、照明ユニット42を点滅させてもよい。さらに、照明制御部43は、照明ユニット42の発光強度を所定の発光強度Iに設定してもよい。この結果、照明ユニット42の照明ユニット42の照明状態の変化が車両1の前方に向けて表示される。
次に、照明ユニットの第2変形例について図6を参照して説明する。図6は、第2変形例に係る照明ユニット42Aが搭載された車両1Aの正面図を示す。本変形例では、照明ユニット42Aは、文字情報M3(“THE CAR WILL STOP SOON”)を停止予告情報として車両1Aのフロントウィンドウ120F上に表示する。照明ユニット42Aは、文字情報M3をフロントウィンドウ120F上に投影するプロジェクタ等の投影装置であって、フロントウィンドウ120F上の所定箇所に配置されている。照明制御部43は、車両制御部3から受信した指示信号に基づいて、照明ユニット42Aを駆動及び制御する。この結果、照明ユニット42Aから投影される停止予告情報が車両1のフロントウィンドウ120F上に表示される。
以下、第2実施形態について図面を参照しながら説明する。尚、第1実施形態の説明において既に説明された部材と同一の参照番号を有する部材については、説明の便宜上、その説明は省略する。また、本図面に示された各部材の寸法は、説明の便宜上、実際の各部材の寸法とは異なる場合がある。
次に、図9及び図10を参照して、光パターンを対象物である歩行者に向けて照射する処理について説明する。図9は、照明ユニット42Bが光パターンを歩行者に向けて照射する状態を示している。図10は、光パターンを歩行者に向けて照射する処理を示すフローチャートを示す。
次に、図11及び図12を参照して、光パターンを対象物である緊急車両(救急車、パトカー、消防車等)に向けて照射する処理について説明する。図11は、照明ユニット42Bが光パターンを緊急車両60に向けて照射する状態を示している。図12は、光パターンを緊急車両60に向けて照射する処理を示すフローチャートを示す。
次に、車両システム2Cと携帯端末50とからなる車両用システム300について図13を参照して説明する。車両用システム300は、車両システム2Cと、携帯端末50を備える。車両システム2Cは、車両用照明装置4Cを除いて図8に示した車両システム2Bと同一の構成を有する。以下では、既に説明した構成要素と同一の符号を有する構成要素についての説明は適宜省略する。
最初に、車両制御部3が図9に示す歩行者P1を検出して、歩行者P1の位置情報を取得する。次に、車両制御部3は、車両システム2Cと歩行者P1の携帯端末50との間の無線通信(アドホック通信)を確立するため、無線通信部10を介して通信要求信号を歩行者P1に向けて送信する。その後、携帯端末50の無線通信部51が当該通信要求信号を受信した後に、制御部52が所定の処理を行う。その後、無線通信部51は、通信要求信号に対する応答信号を無線通信部10に向けて送信する。このようにして、車両システム2Aと携帯端末50との間の無線通信が確立される。
最初に、車両システム2Cと携帯端末50との間の無線通信が確立された後、制御部52は、表示部53の照明状態についての情報を含む照明制御信号を生成する。そして、無線通信部51は当該照明制御信号を無線通信部10に送信する。無線通信部10が無線通信部51から照明制御信号を受信したとき、当該受信した照明制御信号が照明制御部43Cに送信される。その後、照明制御部43Cは、照明制御信号に基づいて、照明ユニット45の照明状態が表示部53の照明状態と対応するように照明ユニット45を制御する。例えば、照明制御部43Cは、照明ユニット45の照明色が表示部53の照明色と同じとなるように照明ユニット45を制御する。また、照明制御部43Cは、照明ユニット45が表示部53と同期点滅するように照明ユニット45を制御する。
次に、車両システム2Cと緊急車両60とからなる車両用システム400について図14を参照して説明する。車両用システム400は、車両システム2Cと、緊急車両60を備える。緊急車両60は、無線通信部61(第2無線通信部)と、制御部62と、表示部63を備える。無線通信部61は、車両システム2Cの無線通信部10と無線通信(アドホック通信)を行うように構成されている。無線通信部61は、無線通信部10とアドホックモードで直接通信してもよいし、アクセスポイントを介して通信してもよい。表示部63は、例えば、運転者に向けて表示されるインジケータであって、光を照射するように構成されている。制御部62は、表示部63の照明状態(照明色、点滅等)を制御するように構成されている。特に、制御部62は、表示部63の照明状態が照明ユニット45の照明状態と対応するように表示部63を制御するように構成されている。
