Abstract
Description
しかしながら、自車両の直前を走行する先行車(つまり前走車)に枠を表示するだけでは、この先行車が自車両の経路案内に対して有用であるとは限らず、この先行車の経路案内が自車両の経路案内とは異なる虞があり、所望の実用性を確保することはできないという問題が生じる。
また、常に先行車が存在するとは限らず、この場合には、虚像表示によって視認性が低下してしまう虞がある。
(1)本発明の一態様に係るナビゲーションシステムは、複数の車両と、前記複数の車両と通信接続可能なサーバ装置と、を備え、各前記複数の車両は、走行時の現在位置の情報と経路情報または目的地情報とを前記サーバ装置に送信する車両制御手段と、フロントウィンドウの所定領域または運転者から見て前記フロントウィンドウ越しの外界に重畳する領域を表示画面とするヘッドアップディスプレイまたは前記外界の所定領域を撮像する撮像手段により撮像された外界画像を前記車両の室内であって前記フロントウィンドウとは異なる位置に設けられた表示画面に表示する表示装置と、を備え、前記サーバ装置は、各前記車両に対して、各前記車両の前記現在位置の所定範囲内に存在し、かつ前記経路情報の少なくとも一部が共通または前記目的地情報が同一である他車両の車両情報を各前記車両に送信するサーバ制御手段を備え、前記車両制御手段は、前記サーバ装置から送信された前記車両情報に基づき、前記表示画面における前記他車両にマーキング表示を行なう。
これらにより、実風景上の複数の適切な他車両によって経路案内を行なうことができ、経路案内の実用性および利便性を向上させることができる。
さらに、例えば他車両の車両情報をサーバ装置から受信していない場合であっても、前走車の方向指示灯の点灯に基づいて経路案内を適切に行なうことができる。
本実施の形態によるナビゲーションシステム1は、例えば図1に示すように、複数の車両2と、これらの複数の車両2と通信可能なサーバ装置3とを備え、複数の車両2とサーバ装置3とは、各種の情報を送受信するためのクライアントサーバー型の無線ネットワークシステムを構成している。
また、ナビゲーション装置11は、さらに、車両2の速度およびヨーレートなどに基づく自律航法の演算処理を併用して、車両2の現在位置を検出可能である。
地図データは、例えば、車両2の現在位置に基づくマップマッチングの処理に必要とされる道路上の位置座標を示す道路座標データと、経路探索や経路誘導などの処理に必要とされる道路データと、を備えている。
道路データは、例えば、交差点および分岐点などの道路上の所定位置の緯度および経度からなる座標点であるノードおよび各ノード間を結ぶ線であるリンクと、道路形状および道路種別と、道路の幅員データおよび制限速度となどを備えている。
また、ナビゲーション装置11は、例えば、車両2の経路探索や経路誘導などの処理を実行し、表示画面での地図表示に対して、例えば目的地や経由地の経路情報などの各種の情報を付加する。
例えば、撮像装置は、車両2の外界(進行方向前方の外界など)に設定された撮像領域を撮像して得た画像に所定の画像処理を行なって画像データを生成し、この画像データを出力する。
スイッチ13から出力される各種の信号は、例えば、運転者による方向指示灯の操作状態(点灯操作など)に係る信号と、運転者によるブレーキペダルやアクセルペダルの操作状態(例えば、操作位置など)に係る信号と、などである。
例えば、車両通信制御部22は、適宜のタイミングでナビゲーション装置11により検出された車両2の現在位置の情報(位置情報)と、ナビゲーション装置11により設定された案内経路などの経路情報および経由地や目的地などの目的地情報とを、サーバ装置3に送信する。
通信装置31は、車両2の車両通信装置14と通信可能であって、車両2の車両通信装置14に対する直接的な無線通信接続または所定の通信網を介した通信接続によって、各種の情報を送受信する。
例えば、通信制御部41は、各車両2から送信されて通信装置31により受信された各車両2の位置情報と、経路情報および目的地情報とを取得して、情報記憶部42に出力する。
また、情報記憶部42は、例えば、各車両2の位置情報と経路情報および目的地情報とに基づいて、サーバ制御部43により生成された各種の情報を記憶する。
また、サーバ装置3のサーバ制御装置32は、例えば、各車両2から位置情報および目的地情報のみを受信した場合には、これらの情報に応じた案内経路などの経路情報を生成してもよい。
そして、例えば図2に示すように、各他車両に対して、車両2との関係に関する情報に応じて異なる表示形態のマーキング表示を行なう。
また、例えば、車両2と目的地(目的地B)は異なるが進行方向は同一である他車両(第2他車両)V2に対して、赤色の逆三角形の画像P2によるマーキング表示が行なわれる。
また、例えば、車両2と同一の方面に向かい走行している経済走行の他車両(第3他車両)V3に対して、緑色の円形の画像P3によるマーキング表示が行なわれる。
また、例えば図2において、車両2の直前を走行する他車両(第4他車両)V4に対しては、サーバ装置3から車両情報を受信していないことから、マーキング表示は行なわれていない。
なお、他車両の進行方向の変化は、例えば、サーバ装置3から逐次送信される車両情報によって取得可能であるとともに、外界センサ12から出力される画像データなどに基づいて検出可能である。
また、車両2の表示制御部23は、例えば、経路情報の少なくとも一部が共通または目的地情報が同一である他車両を、新たに抽出した場合には、直ちにマーキング表示を開始可能である。
これらにより、実風景上の複数の適切な他車両によって経路案内を行なうことができ、経路案内の実用性および利便性を向上させることができる。
この場合には、サーバ装置3から各車両2に他車両の車両情報が送信される際の通信量を低減することができる。
この場合には、過剰な頻度でのマーキング表示を防止し、運転者の外界の視界を妨げたり、表示画面の表示に対する視認性が低下することを防止し、適切なタイミングでマーキング表示を行なうことができる。
なお、MID(マルチインフォメーションディスプレイ)は、例えば、インストゥルメントパネルにおける運転席前方に対応する位置において、車速計や回転数計などの計器類を備えるメータパネルに表示を行なう表示器である。
