駐車スペースの位置情報は、ナビゲーションシステムの地図情報に含めて記憶してもよい。駐車スペースの位置情報は、外部のサーバ又は施設(駐車場)の管理装置から取得してもよい。
本実施形態の「駐車可能条件」は、自車両Vの駐車が可能な駐車スペースを抽出する観点から定義される。
(1)自車両Vから所定距離範囲である。
(2)駐車スペースが空車である。
(3)障害物が無い。
本実施形態の「駐車推奨条件」は、駐車に要するコスト(「駐車所要コスト」ともいう。以下同じ。)が低い駐車スペースを抽出する観点から定義される。
(1)駐車に要する切り返し回数が所定回数以下である。
(2)駐車に要する時間が所定時間以下である。
(3)駐車に要する移動距離が所定距離以下である。
制御装置10は、自車両Vの車速に基づいて、注視点距離を算出する。注視点距離は、自車両Vの位置から自車両Vのドライバが注視する位置(注視点)までの距離に対応する。制御装置10は、ドライバが注視する位置に応じた駐車スペースを推奨駐車スペースとして検出する。
また、自車両Vに搭乗することなく、外部から自車両Vに目標駐車スペースMoの設定指令、駐車処理開始指令、駐車中断・中止指令などを送信して駐車を行うリモートコントロールによる駐車処理も可能である。
図7Aに、駐車支援情報の表示方法の一例を示す。図7Aに示す表示例では、二つの表示領域を定義した。
図7Aに示す表示例では、ディスプレイ21の画面を左右に分割し、左側の第1表示領域と右側の第2表示領域を定義する。左側の第1表示領域21aには俯瞰画像(トップビュー)21aを表示し、右側の第2表示領域21bには監視画像(ノーマルビュー)21bを表示する。監視画像21bの上には、メッセージ21cを表示する。第1表示領域21aとしての俯瞰画像21aには選択可能な駐車スペースを示す画像(駐車スペースの境界線)が含まれている。また、俯瞰画像21aの中央には、自車両Vの位置を示す自車両Vのアイコンが表示されている。監視画像21bは、自車両Vの操作状態に応じて異なるカメラ1a~1dの撮像画像を表示できる。図7Aに示す監視画像21bでは、自車両Vのフロントグリル部にカメラ1aの撮像画像が表示されている。自車両Vが後退する際には、リアバンパ近傍に配置されたカメラ1dの撮像画像を表示してもよい。また、本例では、俯瞰画像21aと監視画像21bとを同時にディスプレイ21に示すが、俯瞰画像21aのみをディスプレイ21に示してもよいし、監視画像21bのみをディスプレイ21に示してもよい。
表示エリアの範囲が狭い場合には、駐車スペースが表示エリア外となり、その駐車スペースの映像がディスプレイ21の表示領域内に含まれない場合がある。また、駐車スペースが自車両Vの走路(自車両Vの現在位置)から離れている場合には、駐車スペースが表示エリア外となり、その駐車スペースの映像がディスプレイ21の表示領域内に含まれない場合がある。駐車場の走路の幅(図4A~図4Dにおける幅W1)が広く、走路を挟んだ駐車スペースが離隔している場合は、ディスプレイ21の表示領域のほとんどを走路の映像が占めてしまい、駐車スペースの映像が表示できない場合がある。駐車場の右側又は左側に偏って走行している場合も、右側又は左側の駐車スペースの映像が表示できない場合がある。
(A)駐車スペースの面積のうち、表示領域21aに表れた駐車スペースの面積が所定割合未満である場合。
(B)駐車スペースの面積のうち、表示領域21aに表れない駐車スペースの面積が所定割合以上である場合。
駐車スペースの面積は、制御装置10が予め記憶していてもよいし、検出された駐車スペースの大きさに基づいて算出してもよいし、検出された駐車枠線の長さと、対となる駐車枠線の距離に基づいて算出してもよい。
表示領域21aには、駐車スペースと駐車用の走路とが現れるため、駐車スペースの面積を走路から判断してもよい。この場合には、上記条件を以下のように変更してもよい。
(C)表示領域21aに表れた走路の面積(若しくは表示領域21aに対する走路の映像が占める占有割合)又は走路の幅が所定値以上である場合。
駐車スペースの面積は、表示領域21aの枠内に表示される駐車枠の長さX(X7A,X7B,X7Cを含む。以下同じ。)又は駐車枠の間隔Y(Y7A,Y7B,Y7Cを含む。以下同じ。)の長さで擬制してもよい。
特に限定されないが、本実施形態の駐車枠の長さX、及び駐車枠の間隔Yは、上空の仮想視点から見た俯瞰画像における駐車枠の長さX、及び駐車枠の間隔Yとする。
制御装置10は、駐車枠の全長を推測し、駐車枠の全長から表示領域21aの枠内に表示される駐車枠の長さX7Aを差し引いて、表示領域21aに表れない(隠れた)駐車枠の長さを算出する。
駐車枠の間隔Yに対する、表示領域21aの枠内に表示される(表示されない)駐車枠の長さXの割合を、駐車スペースの全面積(予測面積)に対する、表示領域21aに表れた(表れない)駐車スペースの面積の割合と見做してもよい。駐車枠の全長(Y方向)と駐車枠の間隔Yとは相関するからである。
駐車枠の線が隠れていることから駐車スペースが隠れていることを予測でき、駐車枠の線の隠れ度合に基づいて、駐車スペースの隠れ度合を知ることができる。
例えば、図8Aに示すマークMK1のように、表示領域21aに吹き出しのように図形を描いてもよい。マークMK1は、表示領域21bに表示してもよい。マークMK1の形状、色、態様、表示手法(点滅、フェードイン/フェードアウト表示など)は特に限定されない。テキスト情報を併せて表示してもよい。例えば、「右側/左側に駐車スペースがあります」「駐車スペースが表示できません」「表示領域の外側に駐車スペースがあります」などのテキストをディスプレイ21に表示してもよい。テキスト情報はスピーカ22を介して音声出力してもよい。マークMKは、表示領域21aに表示することが好ましい。表示領域21aに駐車スペースが表示できない場合に、表示領域21aにマークMKを表示させることにより、ドライバを不安にさせないことができる。さらに、本実施形態では、表示領域21aに駐車スペースが表示できない場合にマークMKを表示するため、乗員(ドライバを含む)は、表示領域21aの枠外に駐車スペースが存在することを、瞬時に視認できる。
図8Eに示すように、複数のマークMKのうち、前述した駐車可能条件を満たす駐車可能スペースであり、かつ推奨駐車条件を満たす推奨駐車スペースのマークMKを強調表示してもよい。駐車スペースは表示できないが、駐車スペースを示すマークMKの態様により推奨駐車スペースの存在及びその位置をドライバに伝えることができる。
(2)推奨駐車スペースのマークMKの線の太さを相対的に太くし、その他の駐車スペースのマークMKの線図画像の線の太さを相対的に細くする。
(3)推奨駐車スペースのマークMKの線図を実線とし、その他の駐車スペースのマークMKの線図を破線とする。第1表示態様の線図を二重線とし、第2表示態様の線図を実線又は破線とする。
(4)推奨駐車スペースのマークMKの線図画像の大きさを相対的に大きくし、その他の駐車スペースのマークMKの線図画像の大きさを相対的に小さくする。
(5)推奨駐車スペースのマークMKを点滅表示し、その他の駐車スペースのマークMKを非点滅表示とする。点滅表示とは、所定周期で表示と非表示を繰り返す、又は点灯と消灯とを繰り返す表示である。推奨駐車スペースのマークMKの点滅表示における点滅周期を相対的に短くし、その他の駐車スペースのマークMKの点滅表示における点滅周期を相対的に長くする。
(6)推奨駐車スペースのマークMKの線図の色を、彩色された線図が相対的に近くに見える進出色で表示し、その他の駐車スペースのマークMKの色を、彩色された線図が相対的に遠くに見える後退色で表示する。進出色とは、彩色された線図が相対的に近くに見える色であって、色相環において相対的に暖色系、高明度、高彩度の色であり、例えば黄色、橙色、赤色である。他方後退色とは、彩色された線図が相対的に遠くに見える色であって、色相環において相対的に寒色系、低明度、低彩度の色であり、例えば青色、紫色、黒色である。このような進出色により表示された画像は相対的に強調されて見える。
(7)推奨駐車スペースのマークMKの画素密度を高くし、その他の駐車スペースのマークMKの画素密度を低くする。画素密度とは、線図画像に対応する領域の画素の密度である。画素密度が高いほど強調された表示となり、画素密度が低いほど強調しない表示となる。
このように、本実施形態の制御装置10は、ディスプレイ21に駐車スペースを表示できない場合であっても、表示エリアを拡大した俯瞰画像21aを再作成することにより、表示できなかった駐車スペースをディスプレイ21に表示する。駐車場の路面が広く左右の駐車スペースが操作ディスプレイに表示できない場合であっても、駐車支援処理を実行できる。
