Description

【0001】
【発明の属する技術分野】
本発明は、自車両の前方や後方を横切る歩行者や2輪車等の障害物の存在を他車両に警報するための車両の横切り障害警報装置に関するものである。
【0002】
【従来の技術】
従来は、このように横切り障害物の存在を他車両に警報して注意を促すような装置がなく、本願出願人が特開2000−30197号公報により提案した、赤外線センサなどを用いて歩行者を検出し、これを自車両の運転者に警報する程度のものがあるだけであった。
【0003】
【発明が解決しようとする課題】
しかし、上記した従来の警報装置ではその警報が他車両に伝達されることがないし、かといってこの装置を全車両が搭載したとしても、個々の車両に搭載した当該装置は他車両の前方または後方を横切っている歩行者や2輪車を当該他車両の陰になって検出することができず、これら横切り障害物の存在を運転者は確実に知ることができない。
【0004】
本発明は、横切り障害物の存在を検知したとき、車両に具えられた照明器具を用いて自車両の運転者だけでなく、近くを走行する他車両の運転者にも警報を発して安全運転のための注意を促すようにした装置を提案し、もって上述の問題を解消することを目的とする。

【0014】
請求項に記載の発明による車両の横切り障害警報装置は、請求項1乃至のいずれかに記載の発明において、前記警報のための前記照明器具として、車両に既存の方向指示器を流用するよう構成したことを特徴とするものである。
【0015】
【発明の効果】
請求項1に記載の発明においてはかかる横切り障害物の存在を自車両の運転者だけでなく、近くを走行する他車両の運転者にも警報することができ、付近の全車両の安全運転を克己することができる。
【0019】
請求項に記載の発明によれば、車両の駐車中に上記の障害物検知手段が、車両の前方を横切る障害物の存在を検知するときは、車両に具えられた前照灯を点灯させることにより、後方からの通過車両より横切り障害物の存在を認識し易くなるよう構成したから、駐車中の自車両の後方から通り過ぎる他車両の運転者が、自車両の前方を横切る障害物を見やすくなって安全運転に大いに寄与する。
【0020】
請求項に記載の発明によれば、車載ナビゲーションシステムから車両が片側1車線の道路上に居ることを検知し、且つ、車両の停車中に前記障害物検知手段が、車両の後方を歩道側から道路センターライン方向へ横切る障害物の存在を検知するとき、車両に具えられた後照灯を点灯させることにより、対向車線通過車両から横切り障害物の存在を認識し易くなるよう構成したから、片側1車線の道路上で停車中の自車両の後方を歩道側から道路センターライン方向へ横切る障害物を、対向車線通過車両の運転者が見やすくなって安全運転に大いに寄与する。
【0021】

【0023】
請求項に記載の発明によれば、前記した警報のための前記照明器具として、車両に既存の方向指示器を流用する構成としたから、安価に前記した作用効果を達成することができる。
【0024】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づき詳細に説明する。
図1は、本発明の一実施の形態になる車両の横切り障害警報装置のシステム図であり、1はコントローラを示す。
このコントローラ1には、図示せざる車載された自動変速機の選択レンジを検出する選択レンジ検出手段2からの信号と、車速VSPを検出する車速センサ3からの信号と、障害物検出手段に相当する赤外線センサ群4からの信号と、ナビゲーションシステム5を構成するGPS(全地球測位システム)6および地図データ7から信号とを入力する。
【0025】
上記の自動変速機は、運転者が希望する車両の走行形態に応じて選択する駐車(P)レンジ、後退走行(R)レンジ、中立(N)レンジ、前進自動変速走行(D)レンジ、エンジンブレーキ(Ds)レンジなどのレンジを有し、
Pレンジでは、エンジンからの動力を車輪に伝達しないと共に、車輪を変速機ケースに対して回転不能にロックして車両の駐車状態を達成可能とし、
Rレンジでは、エンジン回転を逆転変速させて車輪に伝達することにより車両の後退走行を可能にし、
Nレンジでは、エンジンからの動力を車輪に伝達しない中立状態にするが、車輪の上記ロックを行わないものとし、
Dレンジでは、エンジン回転を走行状態(停車も含む)に応じ変速して車輪に伝達し、
Dsレンジでは、自動変速機を低速段選択傾向にすると共にエンジンブレーキが効く状態にするものとする。
【0026】
赤外線センサ群4は車両の前端および後端に設けられて、車両の前方および後方を横切る歩行者や2輪車の存在を検知すると共に、これら障害物が車両の左右方向のどちら側へ向け横切っているのかをも検知し得る周知のものとする。
【0027】
コントローラ1は上記の入力情報をもとに図2の制御プログラムを実行して、車両に具えられた図1に示す方向指示器8、前照灯9および後照灯10を選択的に点灯、消灯させることにより、自車両の運転者はもとより他車両の運転者にも横切り障害の存在を警報するものとする。
ここで方向指示器8は横切り障害警報用の照明器具を構成するが、この照明器具は既存の方向指示器8をそのまま流用してもよいし、横切り障害警報用に新設しても勿論よい。
【0028】
しかし、いずれにしても方向指示器8は車両の左右両側に設けると共に、図3に示すように車両11の各側における方向指示器8を複数個1組みとし、例えば前方側の方向指示器8fと、中央の方向指示器8mと、後方の方向指示器8rとで構成する。
また前照灯9および後照灯10についても既存のものを用いたり、必要に応じて追加したり、既存のものを全く用いずに専用のものを新設して用いることができることは言うまでもない。
【0029】
図2につき、図1のコントローラ1が実行する制御プログラムを以下に詳述する。
先ずステップS1において、赤外線センサ群4が自車両の前方または後方を横切る歩行者や2輪車などの障害物(以下、歩行者等と言う)を検知したか否かをチェックする。
歩行者等の存在を検知しなければ本制御プログラムの実行は不要であるから、制御を元に戻してステップS1でのチェックを継続する。
【0030】
歩行者等の存在が検知されるた時はじめてステップS1からステップS2に制御を進め、ここで選択レンジ検出手段2からの信号にもとづき、自動変速機が前記したPレンジ選択中か否かをチェックし、車両11が駐車中か非駐車中かをチェックする。
駐車中ならステップS3において、ステップS1で存在を検知した歩行者等が車両前方に居るのか、或いは車両後方に居るのかを判定する。
【0031】
歩行者等が車両前方に居る場合、ステップS4において、方向指示器8(8f,8m,8r)のうち車両右側面に存在する方向指示器を点滅させ、この点滅に際し車両右側における複数の前後方向に配した方向指示器8f,8m,8rを、歩行者等が存在する車両の前方へ向け照明点が移動して見えるように点滅させる。
ここで方向指示器8f,8m,8rを、歩行者等が存在する車両の前方へ向け照明点が移動して見えるように点滅させるに当たっては、図4に点灯時間および点灯タイミングを示すように、歩行者等が存在する車両の前方の方向指示器8fを、歩行者等が存在しない車両の後方の方向指示器8rよりも点灯時間割合を大きくしたり、これに加えて歩行者等が存在する車両の前方の方向指示器8fを、歩行者等が存在しない車両の後方の方向指示器8rよりも多数回点灯させることで目的を達成することができる。
【0032】
上記のように車両11が道路左側に駐車中で、その前方を歩行者等12が横切る時の状況を図5に示す。
歩行者等12が車両11の前方を矢Aで示すように横切って歩道側から車道側へ出ようとして交通安全上障害となる場合、上記した通り車両右側面に存在する方向指示器8を点滅させることにより、車両を横切る歩行者等12が居ることを警報し、さらに加えて車両右側面の方向指示器8を点滅させるに際し、車両右側における複数の前後方向に配した方向指示器8f,8m,8rを、歩行者等12が存在する車両の前方へ向け照明点が移動して見えるように点滅させることで、歩行者等12が車両の前方に居ることをも警報する。
これにより、駐車している自車両11の右側を通過しようとする後方通過車両13の運転者は、歩行者等12が車両の前方を横切って飛び出す可能性があるのを知ることができ、前もって速度を落とし安全の確認をすることが可能となる。
【0033】
かかる状況のもとでは更に、図2のステップS5において前照灯9を点灯させることにより図5にαで示すごとく歩行者等を照射し、これにより特に夜間において後方通過車両13の運転者が歩行者等12を容易に目視確認し得るようにする。
【0034】
図6に示す状況がそうであるが、ステップS2で自車両11が駐車中であると判定し、且つ、ステップS3で歩行者等12が車両後方に居ると判定する時は、ステップS6において、方向指示器8(8f,8m,8r)のうち車両右側面に存在する方向指示器を点滅させ、この点滅に際し車両右側における複数の前後方向に配した方向指示器8f,8m,8rを、歩行者等が存在する車両の後方へ向け照明点が移動して見えるように点滅させる。
ここで方向指示器8f,8m,8rを、歩行者等が存在する車両の後方へ向け照明点が移動して見えるように点滅させる方法は、図4につき前述したと同じである。
【0035】
図6のように車両11が道路左側に駐車中で、その後方を歩行者等12が矢Bで示すように横切って歩道側から車道側へ出ようとして交通安全上障害となる場合、上記の通り車両右側面に存在する方向指示器8を点滅させることにより、車両を横切る歩行者等12が居ることを警報し、さらに加えて車両右側面の方向指示器8を点滅させるに際し、車両右側における複数の前後方向に配した方向指示器8f,8m,8rを、歩行者等12が存在する車両の後方へ向け照明点が移動して見えるように点滅させることで、歩行者等12が車両の後方に居ることをも警報する。
これにより、駐車中している自車両11の右側を通過しようとする後方通過車両13の運転者は、歩行者等12が車両の後方を横切って飛び出す可能性があるのを知ることができ、前もって速度を落とし安全の確認をすることが可能となる。
【0036】
かかる状況のもとでは、後方通過車両13の前照灯により歩行者等12が照射されるため、後方通過車両13の運転者は夜間でも歩行者等12を容易に目視確認することができるから、また自車両11による照射がこの場合、後方通過車両13にとり逆光となって歩行者等12を目視確認し難くすることから、図5の場合とは異なり自車両11による歩行者等12の照射を行わないこととする。
【0037】
ステップS2で車両11が駐車中でないと判定する時はステップS7において、センサ3で検出した車速VSPを基に自車両11が停車中か走行中かを判定する。
走行中は本警報制御が不要であるから、制御をそのまま終了するが、停車中は以下の警報制御を実行する。
先ずステップS8において、ステップS1で存在を検知した歩行者等12が自車両11を左から右に向け横切っているのか、それとも逆に自車両11を右から左に向け横切っているのかを判定し、
その後、歩行者等12が自車両11をどちら方向に横切っている場合も、ステップS9またはステップS10において、歩行者等12が車両前方に居るのか後方に居るのかを判定する。
【0038】
ステップS7で停車中と判定し、且つ、ステップS8で歩行者等12が自車両11を左から右に向け横切っていると判定し、更にステップS9で歩行者等12が車両前方に居ると判定する時、
つまり図7に示すごとく自車両11が信号待ちや渋滞などのため車線幅内の中央で停車している間に歩行者等12が自車両11の前方を矢Cで示すごとく左から右に向け横切っている時は、
ステップS10において、方向指示器8(8f,8m,8r)のうち、歩行者等12の横切り方向側側に相当した車両右側面に存在する方向指示器を点滅させ、この点滅に際し車両右側における複数の前後方向に配した方向指示器8f,8m,8rを、歩行者等12が存在する車両の前方へ向け照明点が移動して見えるように点滅させる。
ここで方向指示器8f,8m,8rを、歩行者等が存在する車両の前方へ向け照明点が移動して見えるように点滅させる方法は、図4につき前述したと同じである。
【0039】
従って、図7に示すように自車両11が車線幅内の中央で停車している間に歩行者等12が自車両11の前方を矢Cで示すごとく左から右に向け横切る場合、上記した通り車両右側面に存在する方向指示器8を点滅させることにより、対向車両14の運転者に自車両11を横切る歩行者等12が居ることを警報し、さらに加えて車両右側面の方向指示器8を点滅させるに際し、車両右側における複数の前後方向に配した方向指示器8f,8m,8rを、歩行者等12が存在する車両の前方へ向け照明点が移動して見えるように点滅させることで、歩行者等12が車両の前方に居ることをも警報する。
これにより、停車している自車両11の右側を通過しようとする対向車両14の運転者は、歩行者等12が車両11の前方を横切って飛び出す可能性があるのを知ることができ、前もって速度を落とし安全の確認をすることが可能となる。
【0040】
かかる状況のもとでは更に図2のステップS11において、図1に示すGPSからの信号をもとに自車両11の位置を検出すると共に地図データ7からの情報をもとに自車両11が片側1車線道路上に停車しているのか片側複数車線道路上に停車しているのかを判定し、片側1車線道路に居る場合はステップS12で前照灯9を夜間でも消灯させる。
これにより特に夜間に、自車両11の前照灯9による照射が逆光となって対向車両14の運転者が歩行者等12を目視確認し難くなるのを防止することができる。
なおステップS11で自車両11が片側1車線道路上ではなく片側複数車線道路上に停車していると判定する場合は、上記の懸念がないからステップS12をスキップして前照灯9の消灯を行わせず、夜間において前照灯を点灯させ続けることにより右隣の車線を走行する追い抜き車両の運転者が図7の歩行者等12を容易に目視確認し得るようにする。
【0041】
ステップS7で停車中と判定し、且つ、ステップS8で歩行者等12が自車両11を左から右に向け横切っていると判定し、更にステップS9で歩行者等12が車両後方に居ると判定する時、
つまり図8に示すごとく自車両11が信号待ちや渋滞などのため車線幅内の中央で停車している間に歩行者等12が自車両11の後方を矢Dで示すごとく左から右に向け横切っている時は、
ステップS13において、方向指示器8(8f,8m,8r)のうち、歩行者等12の横切り方向側側に相当した車両右側面に存在する方向指示器を点滅させ、この点滅に際し車両右側における複数の前後方向に配した方向指示器8f,8m,8rを、歩行者等12が存在する車両の後方へ向け照明点が移動して見えるように点滅させる。
ここで方向指示器8f,8m,8rを、歩行者等が存在する車両の後方へ向け照明点が移動して見えるように点滅させる方法は、図4につき前述したと同じである。
【0042】
従って、図8に示すように自車両11が車線幅内の中央で停車している間に歩行者等12が自車両11の後方を矢Dで示すごとく左から右に向け横切る場合、上記した通り車両右側面に存在する方向指示器8を点滅させることにより、対向車両14の運転者に自車両11を横切る歩行者等12が居ることを警報し、さらに加えて車両右側面の方向指示器8を点滅させるに際し、車両右側における複数の前後方向に配した方向指示器8f,8m,8rを、歩行者等12が存在する車両の後方へ向け照明点が移動して見えるように点滅させることで、歩行者等12が車両の後方に居ることをも警報する。
これにより、停車している自車両11の右側を通過しようとする対向車両14の運転者は、歩行者等12が車両11の後方を横切って飛び出す可能性があるのを知ることができ、前もって速度を落とし安全の確認をすることが可能となる。
【0043】
かかる状況のもとでは更に図2のステップS14において、ステップS11におけると同様にして自車両11が片側1車線道路上に停車しているのか片側複数車線道路上に停車しているのかを判定し、片側1車線道路に居る場合はステップS15で後照灯10を特に夜間において点灯させる。
これにより特に夜間に、自車両11の後照灯10により歩行者等12が図8にβで示すごとくに照射されて対向車両14の運転者が歩行者等12を容易に目視確認し得るようになり、大いに安全運転に寄与することができる。
なおステップS14で自車両11が片側1車線道路上ではなく片側複数車線道路上に停車していると判定する場合は、対向車両14が歩行者等12から離れていて自車両11の後照灯10により歩行者等12を照射する必要がないためと、右側車線を追い抜く車両にとって後照灯10の光線が逆光になって当該右側追い抜き車両の運転者が歩行者等12を目視確認し難くなるため、ステップS15を実行せずに制御を終了して後照灯10の点灯を行わない。
【0044】
ステップS7で停車中と判定し、且つ、ステップS8で歩行者等12が自車両11を右から左に向け横切っていると判定した場合は、ステップS16で歩行者等12が車両前方に居るのか、車両後方に居るのかを判定する。
車両前方に居ると判定するとき、つまり図9に示すごとく自車両11が信号待ちや渋滞などのため車線幅内の中央で停車している間に歩行者等12が自車両11の前方を矢Eで示すごとく右から左に向け横切っている時は、
ステップS17において、方向指示器8(8f,8m,8r)のうち、歩行者等12の横切り方向側側に相当した車両左側面に存在する方向指示器を点滅させ、この点滅に際し車両左側における複数の前後方向に配した方向指示器8f,8m,8rを、歩行者等12が存在する車両の前方へ向け照明点が移動して見えるように点滅させる。
ここで方向指示器8f,8m,8rを、歩行者等が存在する車両の前方へ向け照明点が移動して見えるように点滅させる方法は、図4につき前述したと同じである。
【0045】
従って、図9に示すように自車両11が車線幅内の中央で停車している間に歩行者等12が自車両11の前方を矢Eで示すごとく右から左に向け横切る場合、上記した通り車両左側面に存在する方向指示器8を点滅させることにより、2輪車15などの左側追い抜き車両の運転者に自車両11を横切る歩行者等12が居ることを警報し、さらに加えて車両左側面の方向指示器8を点滅させるに際し、車両左側における複数の前後方向に配した方向指示器8f,8m,8rを、歩行者等12が存在する車両の前方へ向け照明点が移動して見えるように点滅させることで、歩行者等12が車両の前方に居ることをも警報する。
これにより、停車している自車両11の左側を通過しようとする2輪車15などの運転者は、歩行者等12が車両11の前方を横切って飛び出す可能性があるのを知ることができ、前もって速度を落とし安全の確認をすることが可能となる。
【0046】
かかる状況のもとでは更に図2のステップS18において、前照灯9を点灯させることにより照射光線αで歩行者等12を照明し、これにより2輪車15などの左側追い抜き車両の運転者が歩行者等12を容易に目視確認し得るようにする。
【0047】
ステップS7で停車中と判定し、且つ、ステップS8で歩行者等12が自車両11を右から左に向け横切っていると判定し、更にステップS16で歩行者等12が車両後方に居ると判定する時、
つまり図10に示すごとく自車両11が信号待ちや渋滞などのため車線幅内の中央で停車している間に歩行者等12が自車両11の後方を矢Fで示すごとく右から左に向け横切っている時は、
ステップS19において、方向指示器8(8f,8m,8r)のうち、歩行者等12の横切り方向側側に相当した車両左側面に存在する方向指示器を点滅させ、この点滅に際し車両左側における複数の前後方向に配した方向指示器8f,8m,8rを、歩行者等12が存在する車両の後方へ向け照明点が移動して見えるように点滅させる。
ここで方向指示器8f,8m,8rを、歩行者等が存在する車両の後方へ向け照明点が移動して見えるように点滅させる方法は、図4につき前述したと同じである。
【0048】
従って、図10に示すように自車両11が車線幅内の中央で停車している間に歩行者等12が自車両11の後方を矢Fで示すごとく右から左に向け横切る場合、上記した通り車両左側面に存在する方向指示器8を点滅させることにより、2輪車15などの左側追い抜き車両の運転者に自車両11を横切る歩行者等12が居ることを警報し、さらに加えて車両左側面の方向指示器8を点滅させるに際し、車両左側における複数の前後方向に配した方向指示器8f,8m,8rを、歩行者等12が存在する車両の後方へ向け照明点が移動して見えるように点滅させることで、歩行者等12が車両の後方に居ることをも警報する。
これにより、停車している自車両11の左側を通過しようとする2輪車15などの左側追い抜き車両の運転者は、歩行者等12が車両11の後方を横切って飛び出す可能性があるのを知ることができ、前もって速度を落とし安全の確認をすることが可能となる。
【0049】
なお、かかる状況のもとで自車両11の後照灯10を、図8につき前述したごとくに点灯すると、これが2輪車15などの左側追い抜き車両の運転者にとって逆光になり、歩行者等12の目視確認が困難になるから、この場合は安全運転のために後照灯10を点灯させないこととする。

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a system diagram of a vehicle crossing fault alarm device according to an embodiment of the present invention. Reference numeral 1 denotes a controller.
The controller 1 corresponds to a signal from a selection range detection unit 2 that detects a selection range of an on-vehicle automatic transmission (not shown), a signal from a vehicle speed sensor 3 that detects a vehicle speed VSP, and an obstacle detection unit. A signal from the infrared sensor group 4 to be transmitted and a signal from the GPS (Global Positioning System) 6 and the map data 7 constituting the navigation system 5 are input.
[0025]
The automatic transmission includes a parking (P) range, a reverse travel (R) range, a neutral (N) range, a forward automatic shift travel (D) range, an engine, which are selected according to the travel mode desired by the driver. It has a range such as a brake (Ds) range,
In the P range, the power from the engine is not transmitted to the wheels, and the wheels can be locked against the transmission case so that the vehicle can be parked.
In the R range, the reverse rotation of the engine rotation is transmitted to the wheels to allow the vehicle to travel backwards.
In the N range, the power from the engine is in a neutral state where the power is not transmitted to the wheel, but the wheel is not locked.
In the D range, the engine rotation is shifted according to the running state (including stopping) and transmitted to the wheels.
In the Ds range, the automatic transmission is set to a low-speed stage selection tendency and the engine brake is effective.
[0026]
Infrared sensor groups 4 are provided at the front and rear ends of the vehicle to detect the presence of pedestrians and two-wheeled vehicles that cross the front and rear of the vehicle, and these obstacles cross to which side of the vehicle in the left-right direction. It is assumed to be a well-known one that can detect whether it is present.
[0027]
The controller 1 executes the control program shown in FIG. 2 based on the input information, and selectively turns on the direction indicator 8, the headlamp 9, and the headlamp 10 shown in FIG. By turning off the light, the driver of the own vehicle as well as the driver of the other vehicle is warned of the presence of the obstacle across the vehicle.
Here, the direction indicator 8 constitutes a lighting device for crossing fault warning. However, this lighting unit may be diverted from the existing direction indicator 8 or may be newly provided for crossing fault warning.
[0028]
However, in any case, the direction indicators 8 are provided on both the left and right sides of the vehicle, and as shown in FIG. 3, a plurality of the direction indicators 8 on each side of the vehicle 11 are set as one set, for example, the front direction indicator 8f. And a central direction indicator 8m and a rear direction indicator 8r.
Needless to say, existing headlights 9 and rearlights 10 can be used as they are, added as necessary, or dedicated ones can be newly installed without using any existing ones.
[0029]
A control program executed by the controller 1 of FIG. 1 will be described in detail below with reference to FIG.
First, in step S1, it is checked whether or not the infrared sensor group 4 has detected an obstacle (hereinafter referred to as a pedestrian or the like) such as a pedestrian or a two-wheeled vehicle that crosses the front or rear of the host vehicle.
If the presence of a pedestrian or the like is not detected, it is not necessary to execute this control program.
[0030]
Only when the presence of a pedestrian or the like is detected, control proceeds from step S1 to step S2, where it is checked based on the signal from the selection range detection means 2 whether the automatic transmission is selecting the P range described above. Then, it is checked whether the vehicle 11 is parked or not parked.
If the vehicle is parked, it is determined in step S3 whether the pedestrian or the like whose presence was detected in step S1 is in front of the vehicle or behind the vehicle.
[0031]
When a pedestrian or the like is in front of the vehicle, in step S4, the direction indicator existing on the right side of the vehicle is blinked among the direction indicators 8 (8f, 8m, 8r), and a plurality of front and rear directions on the right side of the vehicle are blinked. The direction indicators 8f, 8m, and 8r arranged in are blinked so that the illumination point moves toward the front of the vehicle where a pedestrian or the like is present.
Here, when blinking the direction indicators 8f, 8m, and 8r so that the illumination point moves toward the front of the vehicle in which a pedestrian or the like is present, as shown in FIG. The direction indicator 8f in the front of the vehicle in which a pedestrian or the like is present has a longer lighting time ratio than the direction indicator 8r in the rear of the vehicle in which no pedestrian or the like is present, or in addition, there are pedestrians or the like. The purpose can be achieved by lighting the direction indicator 8f in front of the vehicle more times than the direction indicator 8r in the rear of the vehicle where no pedestrian or the like is present.
[0032]
FIG. 5 shows a situation when the vehicle 11 is parked on the left side of the road as described above and a pedestrian 12 crosses the front of the vehicle 11.
When a pedestrian 12 crosses the front of the vehicle 11 as indicated by an arrow A and tries to exit from the sidewalk side to the roadway side, which causes a traffic safety obstacle, the direction indicator 8 present on the right side of the vehicle flashes as described above. To warn that there are pedestrians 12 crossing the vehicle, and in addition to blinking the direction indicator 8 on the right side of the vehicle, the direction indicators 8f and 8m arranged in a plurality of front and rear directions on the right side of the vehicle. , 8r are blinked so that the illumination point moves toward the front of the vehicle where the pedestrian 12 is present, so that the pedestrian 12 is also in front of the vehicle.
As a result, the driver of the backward passing vehicle 13 trying to pass the right side of the parked own vehicle 11 can know that the pedestrian 12 may jump out across the front of the vehicle in advance. It becomes possible to confirm the safety at a reduced speed.
[0033]
In such a situation, the headlamp 9 is turned on in step S5 in FIG. 2 to irradiate a pedestrian or the like as indicated by α in FIG. The pedestrian 12 can be easily visually confirmed.
[0034]
The situation shown in FIG. 6 is the same, but when it is determined in step S2 that the host vehicle 11 is parked, and it is determined in step S3 that pedestrians 12 are behind the vehicle, in step S6, Of the direction indicators 8 (8f, 8m, 8r), the direction indicators existing on the right side of the vehicle are blinked, and at the time of blinking, the direction indicators 8f, 8m, 8r arranged in the front and rear directions on the right side of the vehicle are walked. Blink so that the illumination point moves toward the rear of the vehicle where the person is present.
Here, the method of blinking the direction indicators 8f, 8m, and 8r so that the illumination point moves toward the rear of the vehicle where a pedestrian or the like is present is the same as described above with reference to FIG.
[0035]
When the vehicle 11 is parked on the left side of the road as shown in FIG. 6 and the pedestrians 12 cross the back as indicated by the arrow B and exit from the sidewalk side to the roadside side, it becomes an obstacle for traffic safety. By flashing the direction indicator 8 present on the right side of the vehicle, it is warned that there are pedestrians 12 crossing the vehicle, and in addition, when the direction indicator 8 on the right side of the vehicle is flashed, By blinking the direction indicators 8f, 8m, and 8r arranged in a plurality of front and rear directions so that the illumination point moves toward the rear of the vehicle where the pedestrian 12 is present, the pedestrian 12 is connected to the vehicle. Also warns you that you are behind.
As a result, the driver of the rear passing vehicle 13 trying to pass the right side of the parked own vehicle 11 can know that the pedestrian 12 may jump out across the rear of the vehicle, It becomes possible to confirm the safety at a reduced speed in advance.
[0036]
Under such circumstances, since the pedestrians 12 are irradiated by the headlamps of the backward passing vehicle 13, the driver of the backward passing vehicle 13 can easily visually check the pedestrians 12 even at night. Further, in this case, the irradiation of the pedestrian 12 by the own vehicle 11 is different from the case of FIG. Will not be performed.
[0037]
When it is determined in step S2 that the vehicle 11 is not parked, it is determined in step S7 whether the host vehicle 11 is stopped or traveling based on the vehicle speed VSP detected by the sensor 3.
Since this alarm control is unnecessary during traveling, the control is terminated as it is, but the following alarm control is executed while the vehicle is stopped.
First, in step S8, it is determined whether the pedestrian 12 having detected presence in step S1 is traversing the own vehicle 11 from left to right, or conversely, is traversing the own vehicle 11 from right to left. ,
Thereafter, whether the pedestrian 12 is in front of the vehicle or the rear is determined in step S9 or step S10, regardless of which direction the pedestrian 12 crosses the host vehicle 11.
[0038]
In step S7, it is determined that the vehicle is stopped, and in step S8, it is determined that the pedestrian 12 is crossing the host vehicle 11 from the left to the right. Further, in step S9, it is determined that the pedestrian 12 is in front of the vehicle. when doing,
That is, as shown in FIG. 7, while the own vehicle 11 stops at the center in the lane width because of waiting for traffic lights or traffic jams, the pedestrians 12 turn the front of the own vehicle 11 from left to right as indicated by an arrow C. When crossing
In step S10, among the direction indicators 8 (8f, 8m, 8r), the direction indicators existing on the right side of the vehicle corresponding to the crossing direction side of the pedestrians 12 are blinked, and a plurality of indicators on the right side of the vehicle are blinked. The direction indicators 8f, 8m, 8r arranged in the front-rear direction are blinked so that the illumination point moves toward the front of the vehicle where the pedestrian 12 is present.
Here, the method of blinking the direction indicators 8f, 8m, and 8r so that the illumination point moves toward the front of the vehicle where a pedestrian or the like is present is the same as described above with reference to FIG.
[0039]
Therefore, as shown in FIG. 7, when the pedestrian 12 crosses the front of the host vehicle 11 from the left to the right as indicated by the arrow C while the host vehicle 11 stops at the center within the lane width, By flashing the direction indicator 8 present on the right side of the vehicle, the driver of the oncoming vehicle 14 is warned that there are pedestrians 12 crossing the host vehicle 11, and in addition, the direction indicator on the right side of the vehicle When blinking 8, the direction indicators 8 f, 8 m, 8 r arranged in the front-rear direction on the right side of the vehicle are blinked so that the illumination point moves toward the front of the vehicle where pedestrians 12 are present. Thus, an alarm is also given that the pedestrian 12 is in front of the vehicle.
As a result, the driver of the oncoming vehicle 14 trying to pass the right side of the parked host vehicle 11 can know that the pedestrian 12 may jump out of the front of the vehicle 11 in advance. It becomes possible to confirm the safety at a reduced speed.
[0040]
In such a situation, in step S11 of FIG. 2, the position of the host vehicle 11 is detected based on the signal from the GPS shown in FIG. It is determined whether the vehicle is stopped on a one-lane road or a single-lane road. If the vehicle is on a one-lane road, the headlamp 9 is turned off at night in step S12.
Accordingly, it is possible to prevent the driver of the oncoming vehicle 14 from having difficulty in visually confirming the pedestrian 12 or the like due to the backlit light emitted from the headlamp 9 of the own vehicle 11 particularly at night.
If it is determined in step S11 that the host vehicle 11 is not stopping on a single lane road on one side but on a single lane road on one side, skip step S12 and turn off the headlamp 9 because there is no such concern. The driver of the overtaking vehicle traveling in the lane on the right side can easily visually check the pedestrian 12 or the like in FIG.
[0041]
In step S7, it is determined that the vehicle is stopped, and in step S8, it is determined that the pedestrian 12 is crossing the host vehicle 11 from the left to the right. Further, in step S9, it is determined that the pedestrian 12 is behind the vehicle. when doing,
That is, as shown in FIG. 8, while the own vehicle 11 is stopped at the center in the lane width because of waiting for traffic lights or traffic jams, the pedestrians 12 turn the rear of the own vehicle 11 from the left to the right as indicated by the arrow D. When crossing
In step S13, among the direction indicators 8 (8f, 8m, 8r), the direction indicator existing on the right side of the vehicle corresponding to the crossing direction side of the pedestrian 12 is blinked, and a plurality of indicators on the right side of the vehicle are blinked. The direction indicators 8f, 8m, and 8r arranged in the front-rear direction are blinked so that the illumination point moves toward the rear of the vehicle on which the pedestrian 12 is present.
Here, the method of blinking the direction indicators 8f, 8m, and 8r so that the illumination point moves toward the rear of the vehicle where a pedestrian or the like is present is the same as described above with reference to FIG.
[0042]
Therefore, as shown in FIG. 8, when the pedestrian 12 crosses the rear of the host vehicle 11 from the left to the right as indicated by the arrow D while the host vehicle 11 stops at the center in the lane width, By flashing the direction indicator 8 present on the right side of the vehicle, the driver of the oncoming vehicle 14 is warned that there are pedestrians 12 crossing the host vehicle 11, and in addition, the direction indicator on the right side of the vehicle When blinking 8, the direction indicators 8 f, 8 m, and 8 r arranged in the front-rear direction on the right side of the vehicle are blinked so that the illumination point moves toward the rear of the vehicle where the pedestrians 12 are present. Thus, an alarm is also given that the pedestrian 12 is behind the vehicle.
As a result, the driver of the oncoming vehicle 14 who wants to pass the right side of the parked host vehicle 11 can know that there is a possibility that the pedestrian 12 and the like may jump out across the rear of the vehicle 11 in advance. It becomes possible to confirm the safety at a reduced speed.
[0043]
Under such circumstances, it is further determined in step S14 of FIG. 2 whether the host vehicle 11 is stopped on one lane road or one lane road in the same manner as in step S11. If the vehicle is on a one-lane road, the rear lamp 10 is turned on in step S15, particularly at night.
Thereby, especially at night, the pedestrian 12 is irradiated by the rear lamp 10 of the host vehicle 11 as shown by β in FIG. 8 so that the driver of the oncoming vehicle 14 can easily visually check the pedestrian 12. Can greatly contribute to safe driving.
If it is determined in step S14 that the host vehicle 11 is not stopping on one side lane road but on one side lane road, the oncoming vehicle 14 is away from the pedestrians 12 and the like, and the headlight 11 10, it is not necessary to irradiate the pedestrian etc. 12, and for the vehicle passing the right lane, the light of the headlight 10 is backlit and the driver of the right passing vehicle becomes difficult to visually check the pedestrian etc. 12. Therefore, the control is terminated without executing step S15, and the headlamp 10 is not turned on.
[0044]
If it is determined in step S7 that the vehicle is stopped and it is determined in step S8 that the pedestrian 12 is crossing the vehicle 11 from the right to the left, is the pedestrian 12 in front of the vehicle in step S16? Determine if you are behind the vehicle.
When it is determined that the vehicle is in front of the vehicle, that is, as shown in FIG. 9, a pedestrian or the like 12 moves in front of the vehicle 11 while the vehicle 11 stops in the center of the lane width because of waiting for a signal or traffic jam. When crossing from right to left as shown by E,
In step S17, among the direction indicators 8 (8f, 8m, 8r), the direction indicators existing on the left side of the vehicle corresponding to the crossing direction side of the pedestrian 12 are blinked, and a plurality of indicators on the left side of the vehicle are blinked. The direction indicators 8f, 8m, 8r arranged in the front-rear direction are blinked so that the illumination point moves toward the front of the vehicle where the pedestrian 12 is present.
Here, the method of blinking the direction indicators 8f, 8m, and 8r so that the illumination point moves toward the front of the vehicle where a pedestrian or the like is present is the same as described above with reference to FIG.
[0045]
Therefore, as shown in FIG. 9, when the pedestrian 12 crosses the front of the host vehicle 11 from the right to the left as indicated by the arrow E while the host vehicle 11 stops at the center in the lane width, By flashing the direction indicator 8 present on the left side of the vehicle, the driver of the left overtaking vehicle such as the two-wheeled vehicle 15 is warned that there are pedestrians 12 crossing the own vehicle 11, and in addition to the vehicle When the direction indicator 8 on the left side is blinked, the illumination point moves toward the front of the vehicle where the pedestrians 12 and the like pass through the direction indicators 8f, 8m, and 8r arranged in the front and rear directions on the left side of the vehicle. By blinking so that it can be seen, it is also warned that pedestrians 12 are in front of the vehicle.
As a result, a driver such as a two-wheeled vehicle 15 that tries to pass the left side of the parked vehicle 11 can know that a pedestrian 12 may jump out of the front of the vehicle 11. It is possible to confirm the safety at a reduced speed in advance.
[0046]
Under such circumstances, in step S18 in FIG. 2, the headlamp 9 is turned on to illuminate the pedestrian 12 and the like with the irradiation light α, so that the driver of the left overtaking vehicle such as the two-wheeled vehicle 15 The pedestrian 12 can be easily visually confirmed.
[0047]
In step S7, it is determined that the vehicle is stopped, and in step S8, it is determined that the pedestrian 12 is crossing the vehicle 11 from the right to the left. Further, in step S16, it is determined that the pedestrian 12 is behind the vehicle. when doing,
That is, as shown in FIG. 10, while the own vehicle 11 stops at the center in the lane width because of waiting for traffic lights or traffic jams, the pedestrians 12 turn the rear of the own vehicle 11 from right to left as indicated by the arrow F. When crossing
In step S19, among the direction indicators 8 (8f, 8m, 8r), the direction indicators existing on the left side of the vehicle corresponding to the crossing direction side of the pedestrian 12 are blinked, and a plurality of indicators on the left side of the vehicle are blinked at the time of blinking. The direction indicators 8f, 8m, and 8r arranged in the front-rear direction are blinked so that the illumination point moves toward the rear of the vehicle on which the pedestrian 12 is present.
Here, the method of blinking the direction indicators 8f, 8m, and 8r so that the illumination point moves toward the rear of the vehicle where a pedestrian or the like is present is the same as described above with reference to FIG.
[0048]
Therefore, as shown in FIG. 10, when the pedestrian 12 crosses from the right to the left as indicated by the arrow F while the host vehicle 11 stops at the center in the lane width, By flashing the direction indicator 8 present on the left side of the vehicle, the driver of the left overtaking vehicle such as the two-wheeled vehicle 15 is warned that there are pedestrians 12 crossing the own vehicle 11, and in addition to the vehicle When the direction indicator 8 on the left side is blinked, the illumination point moves toward the rear of the vehicle in which the pedestrians 12 and the like pass through the direction indicators 8f, 8m, and 8r arranged in the front and rear directions on the left side of the vehicle. By blinking so that it can be seen, it is also warned that pedestrians 12 are behind the vehicle.
As a result, the driver of the left overtaking vehicle such as the two-wheeled vehicle 15 trying to pass the left side of the parked host vehicle 11 may cause the pedestrian 12 or the like to jump out across the rear of the vehicle 11. It is possible to know, and it is possible to confirm the safety at a reduced speed in advance.
[0049]
In this situation, if the rear light 10 of the host vehicle 11 is lit as described above with reference to FIG. 8, this is backlit for the driver of the left-handed vehicle such as the two-wheeled vehicle 15, and the pedestrian 12 In this case, the headlamp 10 is not turned on for safe driving.
