を備えたものである。
実施の形態1.
図1は、この発明の実施の形態1による車載狭域無線通信装置を用いた路車間狭域無線通信システムの構成を模式的に示す図であり、一例として、交差点における右折車両(右折途中または右折待ち車両)へ対向車との衝突防止を意図する情報提供を行うシステムを示している。なお、以下の図において、図1と同一の符号を付したものは、同一またはこれに相当するものを示す。
信号制御装置4a、4bは、信号の表示を制御し、路側狭域無線通信装置1に対して、青、赤、黄または右左折矢印等、表示している信号情報を通知する。
センタ10は、交差点周辺における交差点情報、時刻情報、路面情報、天候情報等の環境情報を保有し、これらの環境情報を路側狭域無線通信装置1に入力する。
路側狭域無線通信装置1は、情報出力手段101と、移動体挙動情報取得部102と、信号情報入力部103と、時刻情報取得手段104と、情報蓄積部105と、交差点情報入力部106とを備える。
信号情報入力部103と信号制御装置4a、4bとにより、交差点の信号情報を取得する信号情報取得手段200を構成する。
情報蓄積部105と交差点情報入力部106とセンタ10とにより、交差点における交差点情報、警告情報、および該警告情報を配信するタイミングを規定する配信制御情報を保有する情報保有手段300を構成する。
時刻情報取得手段104は、時刻情報を取得し、情報蓄積部105に記憶する。なお、図2では路側狭域無線通信装置1の内部に時刻情報取得手段104を備えているが、外部から入力しても良い。
なお、これ等の環境情報は、予め情報蓄積部105に記憶されていても良い。
運行状態検出部903と車両制御装置909と車両センサ908とその他の車載機器910とにより、第2移動体9aの挙動情報を取得する挙動情報取得手段500を構成する。
情報提供判断部904とHMI出力制御部906及びパラメータ管理部907とにより、警告情報の内容や警告情報の提供タイミングを判断する情報提供判断手段600を構成する。
State1は、車載装置9が[サービス種別7:右折衝突情報提供サービス]に係るサービスに必要な情報が情報蓄積・管理手段905に存在しない、もしくは、サービス提供対象の交差点を通過している等、サービスの提供が不可能な状態を示す。
State2は、サービスの提供が可能な状態を示す。
State3は、State2のサブ状態であり、サービス中(優先度3)、注意喚起(優先度4、5)のいずれもしていない状態を示す。
State4は、State2のサブ状態であり、注意喚起に値する対向車両が存在しない状態を示す。
State5は、State2のサブ状態であり、注意喚起に値する対向車両が存在する状態を示す。
上記により、対向車情報が取得できなかった場合には、終了する(次回の情報取得まで、処理を行わない)。対向車情報が取得できた場合には、State3に移行する。
ステップST208のTTC演算は、第1の方向6aに沿って交差点7に進入する第1移動体9bが交差点中央に至るまでに必要な所要時間Tp1(車両感知装置3aが検出した第1移動体9bの速度V1と、車両感知装置3aと交差点中央間の距離Lに基づいて、Tp1=L/V1で求められる)と、第2移動体9aが右折に必要な所要時間Tp2と、警告情報の認識可能時間Trのいずれか大きい方と上記第1移動体9b検出後に第2移動体9aのドライバに警告情報が提供されるまでの遅延時間Tds(車両感知装置3aが第1移動体9bを検出した時刻T1と、現在時刻Tを用いて、Tds=T-T1で求められる)の和を、比較することで警告情報の提供可否を判断する。
Tp2>=Trの場合、
Tp1=<Tds+Tp2
が成立するときに警告情報の提供可(第1移動体9bと衝突危険性あり)と判定する。
Tp2<Trの場合、
Tp1=<Tds+Tr
が成立するときに警告情報の提供可(第1移動体9bと衝突危険性あり)と判定する。
ステップST301~ステップST308の動作は、図10のステップST201~ステップST208の動作と共通するため、説明は省略する。ステップST309では、TTC演算式を満たさない場合、つまり本サービスに該当する対向車両が存在しなくなった場合から一定時間経過後には、ステップST311において、当該車両が交差点を通過したと判断してHMI出力制御部906に優先度3の判定結果を送信するとともにState4に移行する。なお、ステップST307に移行して、当該状態が一定時間継続している場合に限り、ステップST310において、サービス終了と判断してHMI出力制御部906に優先度1の判定結果を送信するとともにState1に移行する。当該状態が一定時間継続していない場合には、何もしない。
実施の形態2では、図1に示す交差点において、右折衝突防止サービスのみならず歩行者横断情報提供サービスを同時に提供する場合について説明する。なお、実施の形態2に用いる交差点、路側狭域無線通信装置、車載装置の構成は実施の形態1に係る図1~3と等しいため、その説明は省略する。
情報有効時間は、情報提供可能である有効時間を規定したものであり、再生待ちコンテンツとして一定時間以降経過した場合には情報提供判断部904が情報提供可と判断した時と情報提供出力装置901が再生するまでの時間が長いことを理由に当該コンテンツは破棄する。
上記により、歩行者・自転車情報が取得できなかった場合には、終了する(次回の情報取得まで、処理を行わない)。歩行者・自転車情報が取得できた場合には、State3に移行する。
具体的な判定方法としては、ステップST502では車速が右折走行であると想定される一定速度以下であること、ステップST503では走行車線が右折可能であること、ステップST504では右ターンシグナルが点滅中であること、ステップST505では現在位置が右折先横断歩道付近であること、ステップST506では信号が走行可能な青、もしくは黄であることの全ての要件を満たす場合に第2移動体9aは上記歩行者横断情報を提供すべき右折車両であると判断される。
図18は、実施の形態3に係る車載装置9の構成を示すブロック図である。この実施の形態3では、実施の形態1の車載装置9において、無線通信部902及び情報提供出力装置901を異なる装置(無線通信装置911、情報提供出力装置912)上に配置するとともに、無線通信装置911及び情報提供出力装置912とのインタフェースを追加で備えたものであり、車載装置9と無線通信装置911及び情報提供出力装置912はそれぞれの外部インタフェース913,914を介して接続される。
ステップST602で車載装置9の情報蓄積・管理手段905及び情報提供判断部904が、実施の形態1及び実施の形態2と同一の方法で安全運転支援の可否を判断する。ここで、安全運転支援情報が存在する場合は、HMI出力制御部906に対して安全運転支援情報の出力を要求する。
ステップST603でHMI出力制御部906は、優先度とサービス情報からなるHMI出力要求メッセージ(図20)を生成する。なお、当該HMI出力要求メッセージは実施の形態1における判断結果と同様の構成である。
ステップST604でHMI出力制御部906は、ステップST603で作成したHMI出力要求メッセージを第2の外部インタフェース部914を用いて送信する。
また、サービスの追加時に安全走行支援情報の制御処理部分を専用のサービス種別判断部として独立させることにより、提供サービスの追加等の拡張により容易に対応できるという効果がある。
また、外部インタフェース部として、2種類の外部インタフェース部を用意したが、インターネットプロトコルやCAN等、単一の通信路上の複数のノードCANで通信が可能なネットワークやバス型の通信路を利用する場合は、外部インタフェース部913,914を共用しても良い。
