Abstract
Description
一般的には、車両と対象物との距離や横幅を認識しやすいように、車両の進路予想ガイド線を車両の周辺画像に重畳して表示させる装置が知られている。
また、日本国特公平2-36417号公報には、車両と周辺障害物との距離、タイヤ操舵角、走行速度を含む車両の走行に係る情報信号に応じてマーカー信号を発生し、車両の周辺画像に重畳表示させる装置が開示されている。この装置では、例えば走行速度に応じてマーカー間隔を変化させるようにしている。これにより、安全走行に必要な車間距離を確認することができる。
このように、ブレーキ操作の経過時間に対する車両の速度変化を制動特性として取得することにより、正確な制動特性を容易に取得可能となる。
このように、ブレーキ操作の緊急度合いによって制動範囲に関する画像の区分け表示を行うことにより、運転者に対して制動範囲に関する情報をより詳細に提示することができ、走行時の操作性を向上させることが可能となる。
このように、バック速度の平均値を記憶しておき、実走時のバック速度がこの平均値に基づいて設定されるしきい値を超過する場合に警告画像を重畳させることにより、走行の安全性をより一層高めることが可能となる。また、しきい値の設定において、制動時に記憶したバック速度の平均値を用いる構成としているため、車両および運転者ごとに適切なしきい値を設定することが可能である。なお、バック速度の平均値に基づいて設定されるしきい値とは、平均値より大きい速度で且つ車両の安全走行が確保できる速度である。
このように構成した場合であっても、運転者は車両の制動範囲を把握することができるため、障害物に対してどの位置でブレーキをかければ衝突を回避できるかが明確となり、走行時の安全性を高めることが可能となる。
本発明の実施形態に係る車両のバック走行支援装置1は、主に、撮像光学系2と、撮像部3と、メモリ4と、画像処理部5と、コントローラ部(情報取得部)6とを有する。
撮像部3は、車両に搭載されて前記車両の周辺画像、特に後方画像、を撮像するものであり、撮像光学系2で結像された光学像を電気信号に変換する撮像素子、CCDセンサ、CMOSセンサ等が用いられる。なお、撮像部3と画像処理部5との間には、撮像部3のアナログ出力をデジタル信号に変換するA/D変換器(図示略)を有している。
図1に戻り、画像処理部5とコントローラ部6は、例えばLSIから構成される。
画像処理部5は、撮像部3から出力される撮像画像の画像信号を処理し、生成した画像を表示手段9に出力する。ここで、表示手段9には、例えば車内モニタが用いられる。
コントローラ部6は、車両に搭載される各種センサ等からの情報を取得する。ここで取得する情報は、例えば、シフト位置検出センサ11から取得するシフト位置情報、ブレーキペダルセンサ12から取得するブレーキ操作情報、車速センサ13から取得する車両の速度情報、タイマ14から取得する経過時間情報等である。なお、ここでは一例として、各センサの具体例を示しているが、同様の機能を有する他の種類のセンサを用いてもよい。例えば、ブレーキペダルセンサの代わりに、ブレーキ油圧を検出してブレーキ操作情報を取得する油圧センサやブレーキ変位量検出センサ等を用いてもよい。
また、画像処理部5では、要求されるブレーキ操作の緊急度合いによって制動範囲に関する画像の区分け表示を行うようにしてもよい。この場合、画像処理部5は、例えば危険領域計算手段51のほかに準危険領域計算手段52を含む。準危険領域計算手段52は、車両の衝突可能性範囲に対応した準危険領域を計算するものである。
本実施形態では、危険領域計算手段51および準危険領域計算手段52では、少なくとも車両の速度情報に応じて危険領域および準危険領域を計算している。したがって、速度に応じて危険領域および準危険領域の表示範囲が変わるものである。
図3に示すような後方画像が得られるとき、図4(A)に示すように、低速時においては危険領域および準危険領域の進行方向の長さが短く、高速時においては、危険領域および準危険領域の進行方向の長さが長くなるように表示される。これは、高速時には制動距離が長くなり、低速時には制動距離が短くなるためである。また、危険領域および準危険領域はお互いに異なる色で表示されてもよく、特に、互いの色が補色で表示されてもよい。これにより、車両の制動範囲をより明確に把握する事ができる。
このように、ブレーキ操作の緊急度合いによって制動範囲に関する画像の区分け表示を行うことにより、運転者に対して制動範囲に関する情報をより詳細に提示することができ、バック走行時の操作性を向上させることが可能となる。
次に、車両30が図5の点線36に示す軌跡で駐車枠31内に向かってバック走行している最中に、コントローラ部6は、車速センサ13から現在の車両の速度情報を取得する。そして、図6に示す制動特性を用いて、現在の車両30の速度情報から車両の制動距離を求める。車両30の制動距離は、図6のハッチングで示す面積から求められる。但し、この制動距離は、運転者がすぐにブレーキを踏んでから車両30が停止するまでの距離となる。
停止距離=制動距離+空走距離
一般に、空走距離[m]=反応時間(0.75[s])×車速[m/s]として求めることができる。なお、平均的な人の反応時間は0.75[s]と言われているため、ここでは一例としてこの数値を用いているが、上記に限定されるものではない。また、空走距離は上記の式に基かなくてもよく、一般的な使用状況に基づいて予め設定されてもよい。
このようにして求めた停止距離に応じて、制動範囲に関する画像を撮像画像に重畳表示してもよい。
なお、車両の制動特性は車両の積載状況によっても左右されるため、前記車両の積載状況の情報を取得することで設定されるものであってもよい。また、車両の制動特性は、一般的な使用状況に基づいて、所定値が予め設定されていてもよい。
このテーブルは、停止距離を段階的に分け、停止距離範囲ごとに危険領域を表す画像と準危険領域を表す画像とをそれぞれ格納している。これらの画像は、例えば歪みや画角等の撮像光学系の設計や車載カメラの車体への取り付け条件等に基づいて作成される。
また、予め設定された指定速度以上となったら後方画像20に警告画像26を重畳表示してもよい。この場合、図2に示すように画像処理部5は、コントローラ部6で取得した車両のバック速度の平均値を計算してリングバッファメモリ41に記憶するバック速度平均値計算手段53と、実際の制動時の車両のバック速度と、バック速度の平均値に基づいて設定されるしきい値とを比較して警告表示の有無を判定する警告表示判定手段54とを含む。ここで、警告表示判定手段54は、実走時のバック速度がしきい値を超過した場合に、後方画像20に警告画像26を重畳表示させることが好ましい。
このように、バック速度の平均値を記憶しておき、実走時のバック速度がこの平均値に基づいて設定されるしきい値を超過する場合に警告画像を重畳させることにより、バック走行の安全性をより一層高めることが可能となる。また、しきい値の設定において、実際の制動時に記憶したバック速度の平均値を用いる構成としているため、車両および運転者ごとに適切なしきい値を設定することが可能である。
まず、ステップS1として、コントローラ部6にて、車両に搭載されるシフト位置検出センサ11からシフトレバーの位置を取得し、このシフト位置から車両が現在バック走行中であるか否かを判断する。バック走行中ではないと判断されたとき、ステップS2でブレーキペダルセンサ12からブレーキ操作情報を取得して、ブレーキがかけられているか否かを判断する。ブレーキがかけられていない場合は、ステップS1に戻る。一方、ブレーキがかけられている場合は、ステップS3でブレーキ操作の経過時間に対する車両の速度変化(速度履歴)をリングバッファメモリ41に格納する。ブレーキ操作が行われた後にバック走行せずに前進し、再度ブレーキ操作が行われた場合には、取得した速度履歴を前回の速度履歴に上書きして更新するようにしてもよい。
さらに、ステップS5として、危険領域計算手段51で、現在の車両の速度情報とリングバッファメモリ41に記憶された最新の速度履歴とに基づいて危険領域を計算し、図7に示すテーブルから該当する画像を選択して撮像画像に重畳表示する。
次いで、ステップS7で、バック速度平均値計算手段53にてバック速度の平均値を計算してリングバッファメモリ41に記憶し、ステップS8で、警告表示判定手段54により現在のバック速度とバック速度の平均値に基づいて設定されるしきい値とを比較する。ここで、現在のバック速度がしきい値を超過する場合には、ステップS9で撮像画像に警告画像を重畳表示する。
そして、例えば、前記画像処理部は、表示されたいずれか一方の領域のみを、点滅表示する、もしくは、枠線で囲み枠線を点滅表示してもよい。これにより、運転者は車両の制動範囲を把握することができる。
さらに、前記画像処理部は、ストライプ模様を用いて表示する、もしくは、第1の色と前記第1の色の補色である第2の色によって構成されたストライプ模様を用いて表示するようにしてもよい。これにより、前記画像が異なる色によって表示されているため、車両の制動範囲をより明確に把握する事ができる。これらの場合も、少なくとも車両の速度情報に応じて領域の表示範囲が変わる。
また、危険領域を表す画像と準危険領域の両方を表示し、いずれか一方の領域のみを上記のような種々の様式で表示するように構成してもよい。
この場合も、少なくとも車両の速度情報に応じて領域の表示範囲が変化する。
また、危険領域を表す画像と準危険領域のそれぞれに対応する矢印を表示し、それぞれの領域に対応する矢印を上記のような種々の様式で表示するように構成してもよい。また、危険領域および準危険領域に対応する矢印が互いに異なる色で表示されてもよく、特に、互いの色が補色で表示されてもよい。
このように構成した場合であっても、運転者は車両の制動範囲を把握することができるため、障害物に対してどの位置でブレーキをかければ衝突を回避できるかが明確となり、走行時の安全性を高めることが可能となる。
