Description

【0001】
【発明の属する技術分野】
本発明は、車輌の後方など運転者から見えにくい部分の状況を確認するための車載用視界モニタシステムに関するものである。
【0002】
【従来の技術】
従来より、車輌の走行時に周囲の状況を見ながら運転するための支援装置として、車輌の周囲の状況を監視する車載用視界モニタシステムが提供されている。
【0003】
例えば特許文献1に示されるような車載用視界モニタシステムでは、車輌に搭載されて当該車輌の後方を撮像するカメラと、当該車輌の舵角を検出する舵角センサと、モニタ装置とを備え、図10(a)〜(c)に示すようにモニタ装置の画面W2にカメラの撮像した撮像画像G2を表示するとともに、舵角センサの検出した舵角から車輌が移動すると予測される予想移動軌跡X2を求めて、予想移動軌跡X2を撮像画像G2上に重畳して表示していた。
【0004】
また従来より、カメラによる撮像画像と、障害物検知センサによる障害物の検知情報とを組み合わせて、周囲の状況を監視できるようにした車載用視界モニタシステムも提供されており、例えば特許文献2に示されるような車載用視界モニタシステムでは、車輌に搭載されて当該車輌の後方を撮像するカメラと、当該車輌のコーナー部分に設置されて車輌周辺の障害物を検知する4個の障害物検知センサと、モニタ装置とを備え、図11に示すようにモニタ装置の画面W3を左右二つの領域W31,W32に分割し、右側の領域W31にカメラの撮像した撮像画像G3を表示すると共に、左側の領域W32に各障害物検知センサの検知状況をシンボルS41〜S44の色を変えるなどして表示していた。

特公平2−56876号公報(第1頁−第2頁、及び、第2図)
【0006】
【発明が解決しようとする課題】
上述した後者の車載用視界モニタシステムでは、カメラによる撮像画像と、障害物検知センサによる検知情報とを組み合わせて周囲の状況を監視しているので、周囲の安全をより確実に確認することができるが、モニタ装置の画面W3を2つの領域W31,W32に分割し、それぞれの領域W31,W32に撮像画像G3と障害物検知センサの検知情報を分けて表示しているから、モニタ装置の画面W3を見ても、障害物検知センサが、撮像画像G3内のどの位置にある障害物を検知していて、その障害物が車輌からどのくらいの距離に存在しているのかを、運転者が視覚的に瞬時に判断することが難しく、車輌周辺の状況を把握しにくいという問題があった。
【0007】
そこで、このような問題点を解決するために、図12に示すようにモニタ装置の画面W4にカメラの撮像画像G4を表示すると共に、障害物検知センサの検知情報をそれぞれ表示する検知情報表示領域A1〜A3を画面W4の下側に3つ並べて設け、障害物検知センサの検知情報を撮像画像G4に重畳して表示するような車載用視界モニタシステムが提供されている。このシステムでは、障害物検知センサが検出した障害物までの距離に応じて検知情報表示領域A1〜A3の表示色を変えるなどして、障害物までの距離を表示しているので、運転者が視覚的に車輌周辺の安全を確認し易くなっているが、やはり、障害物検知センサが撮像画像G4内のどの障害物を検知しているのか把握しにくいという問題があった。
【0008】
本発明は上記問題点に鑑みて為されたものであり、その目的とするところは、車輌の周囲の状況を視覚的に確認しやすい車載用視界モニタシステムを提供することにある。
【0009】
【課題を解決するための手段】
上記目的を達成するために、請求項1の発明では、車輌に搭載され当該車輌の周囲を撮像する撮像手段と、車輌に搭載され当該車輌の周囲に設定された検知領域において障害物を検知する複数の障害物検知手段と、撮像手段からの画像信号及び障害物検知手段からの検知信号をもとに、撮像手段の撮像画像に、障害物検知手段が検知した障害物についての検知情報を表す障害物表示シンボルを、当該障害物の検知位置に対応する撮像画像上の位置に重畳した合成画像を作成する合成画像作成手段と、合成画像作成手段が作成した合成画像を表示する画像表示手段とを備え、合成画像作成手段は、障害物表示シンボルとして、障害物までの検知距離と等しい路面上の位置から路面に対して垂直に起立した面内であって、当該障害物を検知した障害物検知手段の検知領域内に、障害物の検知位置を囲む領域を示すシンボルを作成するとともに、障害物表示シンボルに加えて、障害物検知手段の検知領域を示す検知領域表示シンボルを、当該検知領域に対応する撮像画像上の位置に重畳した合成画像を作成することを特徴とする。
【0011】
請求項の発明では、請求項の発明において、合成画像作成手段は、障害物表示シンボルで囲まれる撮像画像の部位を拡大した合成画像を作成することを特徴とする。
【0012】
請求項の発明では、請求項1又は2の何れか1つの発明において、車輌の舵角を検出する舵角検出手段と、舵角検出手段の検出結果から車輌が移動すると予想される予想移動範囲を求める移動範囲予想手段とを設け、合成画像作成手段は、移動範囲予想手段が求めた予想移動範囲内で障害物検知手段が障害物を検知した場合のみ、撮像画像に障害物表示シンボルを重畳させることを特徴とする。
【0014】
請求項の発明では、請求項1乃至の何れか1つの発明において、障害物検知手段が検知した障害物についての検知情報を音声で報知する音声報知手段を備えて成ることを特徴とする。
【0015】
【発明の実施の形態】
本発明に係る車載用視界モニタシステムの一実施形態を図1〜図9に基づいて説明する。
【0016】
図1は、この車載用視界モニタシステムのブロック構成図であり、CCDカメラのようなカメラ1(撮像手段)と、複数(本実施形態では例えば6個)の障害物検知センサ2a〜2f(障害物検知手段)と、車輌の舵角を検出する舵角検出センサ3(舵角検出手段)と、車室内の運転者から視認可能な位置に設置されるTVモニタ4(画像表示手段)と、車室内に設置されるスピーカー5と、制御装置10とで構成される。
【0017】
制御装置10は、CPU11と、各障害物検知センサ2a〜2f毎に設けられた送受信回路12a〜12fと、合成画像作成回路13(合成画像作成手段)と、音声出力回路14とで構成される。
【0018】
カメラ1は、図2(b)に示すように車輌100の後部上方に設置され、車輌100の後方を撮像する。尚、図2(b)中の21はカメラ1の視野を示している。
【0019】
障害物検知センサ2a…は超音波を利用してセンシングを行う超音波検知器からなり、その内の4個の障害物検知センサ2a〜2dは、車輌100の後部のバンパー101に等間隔に装着され(図2(a)(b)参照)、残りの2個の障害物検知センサ2e,2fは前部のバンパー(図示せず)の左右両側に装着される。各障害物検知センサ2a…は、送受信回路12a…から入力される超音波パルス信号によって駆動され、超音波パルスを間欠的に送波して、その後周辺に存在する障害物からの反射波を受波することで障害物を検知するものであり、検知範囲が限定できることや、超音波の伝搬時間をもとに障害物までの距離を測定できるという特徴を有している。なお、図2(a)(b)中の22a〜22dは各障害物検知センサ2a〜2dの検知領域を示している。
【0020】
送受信回路12a…は、CPU11から入力される送波パルス信号を増幅して得た超音波パルス信号を、障害物検知センサ2a…に印加して、障害物検知センサ2a…から超音波パルスを送波させる。障害物検知センサ2a…は、車輌の周囲にある障害物で反射されたパルス状の反射波を受波すると、送受信回路12a…にパルス信号を出力する。そして、送受信回路12a…は、障害物検知センサ2a…から入力された受波パルス信号を増幅してCPU11に出力する。
【0021】
CPU11では、送受信回路12a…から受波パルス信号を受け取ると、送波パルス信号を出力してから受波パルス信号を受け取るまでの時間が、所定の距離範囲に対応する時間内であれば、障害物を検知したと判断して、障害物についての検知情報(障害物を検知した障害物検知センサ2a…の番号や検知した障害物までの距離(この距離を検知距離と言う)など)や、各障害物検知センサ2a〜2fの検知領域の情報を合成画像作成回路13に出力するとともに、何れの障害物検知センサ2a…で障害物を検知したかを示す検知情報を音声出力回路14に出力する。
【0022】
合成画像作成回路13には、カメラ1からの画像信号と、CPU11からの検知情報及び検知領域情報が入力され、カメラ1の撮像画像に、障害物の検知情報を表す障害物表示シンボルと、障害物検知センサ2a…の検知領域を表す検知領域表示シンボルとを重畳した合成画像を作成する。そして、合成画像作成回路13は、作成した合成画像の画像信号をTVモニタ4に出力し、TVモニタ4のモニタ画面4aに合成画像を表示させる。
【0023】
音声出力回路14は、CPU12から検知情報が入力されると、どの部位で障害物を検知したかを示す音声メッセージを音声合成して、スピーカー5から出力させており、何れの障害物検知センサ2a…が障害物を検知したかを運転者に報知する。而して、車両の運転者がTVモニタ4のモニタ画面4aを見ていない場合でも、音声で確実に警告を与えることができる。ここに、音声出力回路14とスピーカ6とで音声報知手段が構成される。
【0024】
次に、図3及び図4を参照して本システムの動作を説明する。図3は、本実施形態の車載用視界モニタシステムを搭載した車輌100が駐車のために後進する際に、この車輌100の後方に別の車輌(検知対象車輌)200が後ろ向きに駐車している状況を示し、図4はこの時のTVモニタ4のモニタ画面4aを示している。
【0025】
検知対象車輌200は、車輌100から距離L1の位置にあり、車輌100の後部バンパー101に装着された4個の障害物検知センサ2a〜2dの検出範囲22a〜22d内に存在するので、全ての障害物検知センサ2a〜2dで検知対象車輌200が検出される。したがって、CPU11には、送受信回路12a〜12dより受波パルス信号が入力され、受波パルス信号の受信時間から検知対象車輌200までの距離が検出される。
【0026】
この時、CPU11は、検知対象車輌200を検知した障害物検知センサ2a〜2dの情報や検知距離L1などの検知情報と、障害物検知センサ2a…の検知領域を示す検知領域情報を合成画像作成回路13に出力するとともに、障害物検知センサ2a〜2dが検知したことを示す検知情報を音声出力回路14に出力する。音声出力回路14は、CPU11からの検知情報に基づいて障害物検知センサ2a〜2dが検知したことを示す音声メッセージを音声合成して、スピーカー5から出力させており、運転者に音声で警告を与える。また、合成画像作成回路13は、CPU11からの検知情報及び検知領域情報に基づいて、障害物検知センサ2a…から検知対象車輌200までの検知距離L1に等しい路面上の位置を示す線状の障害物表示シンボル(以下、シンボルと省略す)S1(図中に実線で示す。)と、検知領域(図中の斜線部)を囲む囲み線のような
検知領域表示シンボル(以下、シンボルと省略す)S2(図中に一点鎖線で示す。)とを作成するとともに、カメラ1の撮像画像G1に、作成したシンボルS1,S2をそれぞれ撮像画像G1上の検知位置及び検知領域に対応する位置に重畳した合成画像を作成し、作成した合成画像の画像信号をTVモニタ4に出力して、TVモニタ4のモニタ画面4aに表示させる。また、図中のS11は、障害物検知センサ2a…からの距離が1mの路面上の位置を示すために、合成画像作成回路13が作成して撮像画像G1に重畳したシンボルである。なお、シンボルS2としては、検知領域に対応する部分の表示色を変えるなどして、検知領域を面で表すようなシンボルとしても良い。
【0027】
このように、本実施形態では検知した障害物についての検知情報を表す障害物表示シンボルとして、障害物検知センサ2a…からの距離が、障害物(検知対象車輌200)までの検知距離L1に等しい路面上の位置を示す線状のシンボルS1を撮像画像G1に重畳してモニタ画面4aに表示させているので、障害物検知センサ2a…がどの障害物を検知しており、その障害物がどれくらいの距離に存在しているか、障害物検知センサ2a…の検知領域がどの領域に設定されているかを運転者が視覚的に容易に把握できる。また、合成画像作成回路13は、検知領域を示す検知領域表示シンボルS1を撮像画像G1に重畳して表示しているので、障害物検知センサ2a〜2dの検知領域を、運転者が視覚的に容易に把握することができる。
【0028】
なお本実施形態では、合成画像作成回路13により、障害物検知センサ2a…からの距離が、障害物(検知対象車輌200)までの検知距離L1に等しい路面上の位置を示す線状のシンボルS1と、検知領域を示すシンボルS2とを作成して、これらのシンボルS1,S2を撮像画像G1に重畳させているが、図5に示すように、障害物検知センサ2a…が検知した障害物(検知対象車輌200)までの距離L1と等しい路面上の位置から、路面に対して垂直に起立した面内にあって、障害物の検知位置を囲む領域(図中の斜線部)を示す囲み線のようなシンボルS3を作成し、このシンボルS3のみを撮像画像G1に重畳してモニタ画面4aに表示させても良いし、図6に示すように上述したシンボルS1〜S3を撮像画像G1に重畳してモニタ画面4aに表示させても良い。
【0029】
また本実施形態では、合成画像作成回路13が、検知対象車輌200を検知した4個の障害物検知センサ2a〜2dの検知領域を1つのシンボルS2で表示しているが、図7に示すように、検知領域を両端の障害物検知センサ2a,2dの検知領域に対応した領域を示すシンボルS21,S23と、中央の障害物検知センサ2b,2cの検知領域に対応した領域を示すシンボルS23に細分化するとともに、
障害物検知センサ2a、障害物検知センサ2b及び2c、障害物検知センサ2dよりそれぞれ障害物の検知距離L1と等しい路面上の位置から、路面に対して垂直に起立した面内にあって、障害物の検知位置を囲む領域(図中の斜線部)を示す囲み線のような3つのシンボルS31,S32,S33を作成して、これらのシンボルS21〜S23、S31〜S33を撮像画像G1に重畳してモニタ画面4aに表示させても良く、それぞれの障害物検知センサ2a〜2dが検知した障害物がどの位置にあるのかを、運転者が視覚的に容易に判断できる。
【0030】
またCPU11には、舵角検出センサ3から舵角の検出結果が入力されているので、この舵角情報をもとに車輌が移動すると予想される予想移動範囲X1を求め、予想移動範囲X1内で障害物検知センサ2a…が障害物を検出した場合のみ、障害物検知センサ2a…が検出した障害物を示すシンボルを撮像画像G1に重畳して表示させるようにしても良い。
【0031】
例えば、図8(b)は、車輌100が旋回後退する場合のモニタ画面4aを示しており、この場合は後部バンパー101の左端に装着された障害物検知センサ2dが検知対象車輌200を検出しているが、検知対象車輌200は予想移動範囲X1の外側に位置し、予想移動範囲X1内で何れの障害物検知センサ2a〜2dも障害物を検知していないので、CPU11は合成画像作成回路13及び音声出力回路14に検知情報を出力せず、合成画像作成回路13は、検知領域を示すシンボルS21〜S23と、距離の目安を示すシンボルS11のみを撮像画像G1に重畳させて、モニタ画面4aに表示させる。
【0032】
一方、図8(a)は、車輌100が直進後退する場合のモニタ画面4aを示しており、この場合は予想移動範囲X1内にある障害物(検知対象車輌200)を、後部バンパー101の左端に装着された障害物検知センサ2dが検出しているので、CPU11は、障害物検知センサ2dの検知情報を合成画像作成回路13及び音声出力回路14に出力する。この時、合成画像作成回路13は、障害物検知センサ2dから検知対象車輌200までの検知距離L1に等しい路面上の位置を示す線状のシンボルS1と、障害物検知センサ2dが検知した検知対象車輌200までの距離L1と等しい路面上の位置から、路面に対して垂直に起立した面内にあって、障害物の検知位置を囲む領域を示す囲み線のようなシンボルS3と、距離の目安を示すシンボルS11と、検知領域(図中の斜線部)を囲む囲み線のようなシンボルS21〜S23と、を作成し、これらのシンボルS1,S3,S11,S21〜S23を撮像画像G1に重畳してモニタ画面4aに表示させている。また、音声出力回路14は、どの部位で障害物を検知したかを示す音声メッセージを音声合成して、スピーカー5から出力させる。而して、予想移動範囲X1内に障害物がいる場合のみ、検知情報を示すシンボルを表示させたり、音声で警報を出力することで、運転者に対し不要な警報を発するのを防止し、確実な報知が行える。
【0033】
ところで、本実施形態において例えば図8(a)に示すように、合成画像作成回路13が、障害物検知センサ2dが検知した検知対象車輌200までの距離L1と等しい路面上の位置から、路面に対して垂直に起立した面内にあって、障害物の検知位置を囲む領域を示す囲み線のようなシンボルS3を作成し、このシンボルS3を撮像画像G1に重畳して表示させる際に、図9に示すように撮像画像G1のシンボルS3で囲まれる部分を拡大してモニタ画面4aに表示させても良く、障害物が拡大して表示されるので、障害物の確認を容易に行える。
【0034】
尚、各シンボルS1…の形状は上記の形状に限定されるものではなく、障害物についての検知情報を表示できるのであれば、どのような形状の形状のシンボルを用いても良い。
【0035】
【発明の効果】
上述のように、請求項1の発明は、車輌に搭載され当該車輌の周囲を撮像する撮像手段と、車輌に搭載され当該車輌の周囲に設定された検知領域において障害物を検知する複数の障害物検知手段と、撮像手段からの画像信号及び障害物検知手段からの検知信号をもとに、撮像手段の撮像画像に、障害物検知手段が検知した障害物についての検知情報を表す障害物表示シンボルを、当該障害物の検知位置に対応する撮像画像上の位置に重畳した合成画像を作成する合成画像作成手段と、合成画像作成手段が作成した合成画像を表示する画像表示手段とを備え、合成画像作成手段は、障害物表示シンボルとして、障害物までの検知距離と等しい路面上の位置から路面に対して垂直に起立した面内であって、当該障害物を検知した障害物検知手段の検知領域内に、障害物の検知位置を囲む領域を示すシンボルを作成するとともに、障害物表示シンボルに加えて、障害物検知手段の検知領域を示す検知領域表示シンボルを、当該検知領域に対応する撮像画像上の位置に重畳した合成画像を作成することを特徴とし、合成画像作成手段は、撮像手段の撮像画像に、障害物検知手段が検知した障害物についての検知情報を表す障害物表示シンボルを、その検知位置に対応する撮像画像上の位置に重畳した合成画像を作成し、この合成画像を画像表示手段に表示させているので、車輌の運転者が、障害物表示シンボルの位置から、障害物検知手段が撮像画像内のどの位置にある障害物を検知したのかを、視覚的に容易に把握できるという効果がある。しかも、合成画像作成手段は、障害物表示シンボルに加えて、障害物検知手段の検知領域を示す検知領域表示シンボルを、当該検知領域に対応する撮像画像上の位置に重畳した合成画像を作成しているので、車輌の運転者が、検知領域表示シンボルから障害物検知手段の検知領域を視覚的に容易に把握できるという効果もある。
【0036】
しかも、障害物表示シンボルは、障害物検知手段との間の距離が、障害物検知手段が検知した障害物までの距離と等しい路面上の位置から、路面に対して垂直に起立した面内にあって、障害物の検知位置を囲む領域を示すシンボルで構成されているので、車輌の運転者は、障害物表示シンボルで囲まれた領域にある障害物を障害物検知手段が検知したことを、容易に把握できるという効果がある。
【0037】
請求項の発明は、請求項の発明において、合成画像作成手段は、障害物表示シンボルで囲まれる撮像画像の部位を拡大した合成画像を作成することを特徴とする。障害物表示シンボルで囲まれる部位を拡大して表示しているので、画像表示手段の表示が見易くなり、車輌の運転者が障害物を容易に把握できるという効果がある。
【0038】
請求項の発明は、請求項1又は2の何れか1つの発明において、車輌の舵角を検出する舵角検出手段と、舵角検出手段の検出結果から車輌が移動すると予想される予想移動範囲を求める移動範囲予想手段とを設け、合成画像作成手段は、移動範囲予想手段が求めた予想移動範囲内で障害物検知手段が障害物を検知した場合のみ、撮像画像に障害物表示シンボルを重畳させることを特徴とし、移動範囲予想手段は舵角検出手段の検出結果から車輌の移動予想範囲を求めており、この移動予想範囲内にある障害物を検知した場合のみ、合成画像作成手段が障害物表示シンボルを撮像画像に重畳して表示しているので、衝突する可能性がある障害物についてのみ障害物表示シンボルを表示させることで、車輌の運転者に対して余計な情報を与えるのを防止できる。
【0040】
請求項の発明は、請求項1乃至の何れか1つの発明において、障害物検知手段が検知した障害物についての検知情報を音声で報知する音声報知手段を備えて成ることを特徴とし、音声報知手段が音声で検知情報を出力しているので、車輌の運転者が、画像表示手段の表示を見ていない場合でも、音声で警告を与えることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a vehicle-mounted visibility monitor system for confirming the situation of a portion that is difficult to be seen by a driver, such as behind a vehicle.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, an in-vehicle visibility monitor system that monitors a surrounding situation of a vehicle has been provided as a support device for driving while looking at the surrounding situation when the vehicle is traveling.
[0003]
For example, an in-vehicle visibility monitor system as shown in Patent Document 1 includes a camera that is mounted on a vehicle and images the rear of the vehicle, a steering angle sensor that detects the steering angle of the vehicle, and a monitor device. As shown in FIGS. 10A to 10C, the captured image G2 captured by the camera is displayed on the screen W2 of the monitor device, and the predicted movement trajectory predicted to move the vehicle from the rudder angle detected by the rudder angle sensor. X2 was obtained, and the predicted movement locus X2 was displayed superimposed on the captured image G2.
[0004]
Conventionally, there has also been provided an in-vehicle field of view monitor system that can monitor surrounding conditions by combining an image captured by a camera and obstacle detection information by an obstacle detection sensor. In the in-vehicle visibility monitor system as shown, a camera that is mounted on a vehicle and images the rear of the vehicle, and four obstacle detection sensors that are installed at corners of the vehicle and detect obstacles around the vehicle. And the monitor device, the screen W3 of the monitor device is divided into two left and right regions W31 and W32 as shown in FIG. 11, and the captured image G3 captured by the camera is displayed in the right region W31, and the left side The detection status of each obstacle detection sensor is displayed in the area W32 by changing the colors of the symbols S41 to S44.
[0005]

Japanese Examined Patent Publication No. 2-56876 (pages 1 and 2 and FIG. 2)
[0006]
[Problems to be solved by the invention]
In the latter in-vehicle visibility monitor system described above, the surrounding situation is monitored by combining the image captured by the camera and the detection information detected by the obstacle detection sensor, so that the surrounding safety can be more reliably confirmed. However, since the screen W3 of the monitor device is divided into two regions W31 and W32, and the captured image G3 and the detection information of the obstacle detection sensor are separately displayed in the respective regions W31 and W32, the screen W3 of the monitor device is displayed. The obstacle detection sensor detects the position of the obstacle in the captured image G3, and the driver visually indicates how far the obstacle is located from the vehicle. However, it is difficult to make an instant determination and it is difficult to grasp the situation around the vehicle.
[0007]
Therefore, in order to solve such a problem, as shown in FIG. 12, the detection information display area for displaying the captured image G4 of the camera on the screen W4 of the monitor device and displaying the detection information of the obstacle detection sensor, respectively.

[0019]
The obstacle detection sensor 2a is composed of an ultrasonic detector that performs sensing using ultrasonic waves, and the four obstacle detection sensors 2a to 2d are mounted on the bumper 101 at the rear of the vehicle 100 at equal intervals. The remaining two obstacle detection sensors 2e and 2f are mounted on both the left and right sides of a front bumper (not shown), respectively (see FIGS. 2A and 2B). Each obstacle detection sensor 2a is driven by an ultrasonic pulse signal input from the transmission / reception circuit 12a, intermittently transmits the ultrasonic pulse, and then receives a reflected wave from an obstacle present in the vicinity. An obstacle is detected by the wave, and the detection range can be limited, and the distance to the obstacle can be measured based on the propagation time of the ultrasonic wave. In addition, 22a-22d in Fig.2 (a) (b) has shown the detection area | region of each obstacle detection sensor 2a-2d.
[0020]
The transmission / reception circuits 12a ... apply ultrasonic pulse signals obtained by amplifying the transmission pulse signals input from the CPU 11 to the obstacle detection sensors 2a ..., and send ultrasonic pulses from the obstacle detection sensors 2a ... Let it wave. When the obstacle detection sensor 2a receives a pulsed reflected wave reflected by an obstacle around the vehicle, it outputs a pulse signal to the transmission / reception circuits 12a. The transmission / reception circuits 12a ... amplify the received pulse signals input from the obstacle detection sensors 2a ... and output them to the CPU 11.
[0021]
In the CPU 11, when the received pulse signal is received from the transmission / reception circuit 12a ..., if the time from the output of the transmitted pulse signal to the reception of the received pulse signal is within the time corresponding to the predetermined distance range, Judging that an object has been detected, detection information about the obstacle (the number of the obstacle detection sensor 2a ... that detected the obstacle, the distance to the detected obstacle (this distance is called the detection distance), etc.) Information of detection areas of the respective obstacle detection sensors 2a to 2f is output to the composite image creation circuit 13, and detection information indicating which obstacle detection sensor 2a...

[0022]
An image signal from the camera 1 and detection information and detection area information from the CPU 11 are input to the composite image creation circuit 13, and an obstacle display symbol representing the detection information of the obstacle is displayed on the captured image of the camera 1. A composite image is created by superimposing detection area display symbols representing detection areas of the object detection sensors 2a. Then, the composite image creation circuit 13 outputs an image signal of the created composite image to the TV monitor 4 and displays the composite image on the monitor screen 4 a of the TV monitor 4.
[0023]
When the detection information is input from the CPU 12, the voice output circuit 14 synthesizes a voice message indicating at which part the obstacle has been detected, and outputs it from the speaker 5, which obstacle detection sensor 2a. Informs the driver whether ... has detected an obstacle. Thus, even when the driver of the vehicle is not looking at the monitor screen 4a of the TV monitor 4, a warning can be reliably given by voice. Here, the voice output circuit 14 and the speaker 6 constitute voice notification means.
[0024]
Next, the operation of this system will be described with reference to FIGS. FIG. 3 shows that when the vehicle 100 equipped with the in-vehicle visibility monitor system of this embodiment moves backward for parking, another vehicle (detection target vehicle) 200 is parked rearward behind the vehicle 100. FIG. 4 shows a monitor screen 4a of the TV monitor 4 at this time.
[0025]
Since the detection target vehicle 200 is located at a distance L1 from the vehicle 100 and exists within the detection ranges 22a to 22d of the four obstacle detection sensors 2a to 2d attached to the rear bumper 101 of the vehicle 100, The detection target vehicle 200 is detected by the obstacle detection sensors 2a to 2d. Therefore, the reception pulse signal is input to the CPU 11 from the transmission / reception circuits 12a to 12d, and the distance from the reception time of the reception pulse signal to the detection target vehicle 200 is detected.
[0026]
At this time, the CPU 11 creates a composite image by detecting the obstacle detection sensors 2a to 2d that have detected the detection target vehicle 200, the detection information such as the detection distance L1, and the detection area information indicating the detection areas of the obstacle detection sensors 2a. While outputting to the circuit 13, the detection information which shows that the obstacle detection sensors 2a-2d detected is output to the audio | voice output circuit 14. The voice output circuit 14 synthesizes a voice message indicating that the obstacle detection sensors 2a to 2d are detected based on the detection information from the CPU 11 and outputs the voice message from the speaker 5, and warns the driver by voice. give. Further, the composite image creation circuit 13 is based on detection information and detection area information from the CPU 11 and shows a linear obstacle indicating a position on the road surface that is equal to the detection distance L1 from the obstacle detection sensor 2a to the detection target vehicle 200. An object display symbol (hereinafter abbreviated as a symbol) S1 (indicated by a solid line in the figure) and a detection area display symbol (hereinafter abbreviated as a symbol) such as a surrounding line surrounding the detection area (the hatched portion in the figure). ) S2 (indicated by the alternate long and short dash line in the figure) is created, and the created symbols S1 and S2 are superimposed on the captured image G1 of the camera 1 at positions corresponding to the detection position and the detection region on the captured image G1, respectively. The synthesized image is created, and the image signal of the created synthesized image is output to the TV monitor 4 and displayed on the monitor screen 4a of the TV monitor 4. S11 in the figure is a symbol created by the composite image creation circuit 13 and superimposed on the captured image G1 in order to indicate a position on the road surface with a distance of 1 m from the obstacle detection sensors 2a. Note that the symbol S2 may be a symbol that represents the detection area by a surface by changing the display color of the portion corresponding to the detection area.
[0027]
Thus, in this embodiment, as an obstacle display symbol representing detection information about the detected obstacle, the distance from the obstacle detection sensor 2a... Is equal to the detection distance L1 to the obstacle (detection target vehicle 200). Since the linear symbol S1 indicating the position on the road surface is superimposed on the captured image G1 and displayed on the monitor screen 4a, the obstacle detection sensor 2a ... detects which obstacle and how much the obstacle is. It is possible for the driver to easily grasp visually which area is set at the distance of the obstacle detection sensor 2a. Further, since the composite image creation circuit 13 displays the detection area display symbol S1 indicating the detection area superimposed on the captured image G1, the driver visually determines the detection areas of the obstacle detection sensors 2a to 2d. It can be easily grasped.
[0028]
In the present embodiment, the composite image creation circuit 13 causes the linear symbol S1 indicating the position on the road surface, where the distance from the obstacle detection sensors 2a... Is equal to the detection distance L1 to the obstacle (detection target vehicle 200). And a symbol S2 indicating the detection area, and these symbols S1 and S2 are superimposed on the captured image G1, but as shown in FIG. 5, the obstacles detected by the obstacle detection sensor 2a. An encircling line indicating a region (hatched portion in the figure) that is in a plane standing upright from the position on the road surface equal to the distance L1 to the detection target vehicle 200) and that surrounds the obstacle detection position. The symbol S3 as shown above may be created and only this symbol S3 may be superimposed on the captured image G1 and displayed on the monitor screen 4a, or the symbols S1 to S3 described above may be superimposed on the captured image G1 as shown in FIG. do it It may be displayed on the screen Nita 4a.
[0029]
Further, in this embodiment, the composite image creation circuit 13 displays the detection areas of the four obstacle detection sensors 2a to 2d that have detected the detection target vehicle 200 with one symbol S2, but as shown in FIG. In addition, symbols S21 and S23 indicating the detection areas corresponding to the detection areas of the obstacle detection sensors 2a and 2d at both ends, and symbols S23 indicating the areas corresponding to the detection areas of the central obstacle detection sensors 2b and 2c, respectively. While subdividing,
The obstacle detection sensor 2a, the obstacle detection sensors 2b and 2c, and the obstacle detection sensor 2d are located in a plane upright from the position on the road surface equal to the obstacle detection distance L1 and perpendicular to the road surface. Three symbols S31, S32, and S33, such as encircling lines that indicate a region surrounding the object detection position (the hatched portion in the figure), are created, and these symbols S21 to S23 and S31 to S33 are superimposed on the captured image G1. Then, it may be displayed on the monitor screen 4a, and the driver can easily visually determine the position of the obstacle detected by the respective obstacle detection sensors 2a to 2d.
[0030]
Further, since the detection result of the steering angle is input to the CPU 11 from the steering angle detection sensor 3, an expected movement range X1 in which the vehicle is expected to move is obtained based on this steering angle information, and the predicted movement range X1 is calculated. Only when the obstacle detection sensor 2a detects an obstacle, a symbol indicating the obstacle detected by the obstacle detection sensor 2a may be superimposed on the captured image G1 and displayed.
[0031]
For example, FIG. 8B shows a monitor screen 4a when the vehicle 100 turns back and forth. In this case, the obstacle detection sensor 2d attached to the left end of the rear bumper 101 detects the detection target vehicle 200. However, since the detection target vehicle 200 is located outside the expected movement range X1 and none of the obstacle detection sensors 2a to 2d has detected an obstacle within the expected movement range X1, the CPU 11 performs a composite image generation circuit. 13 and the audio output circuit 14 do not output the detection information, and the composite image creation circuit 13 superimposes only the symbols S21 to S23 indicating the detection area and the symbol S11 indicating the distance standard on the captured image G1, and displays the monitor screen. 4a is displayed.
[0032]
On the other hand, FIG. 8A shows a monitor screen 4a when the vehicle 100 moves straight back and forth. In this case, an obstacle (detection target vehicle 200) within the expected movement range X1 is moved to the left end of the rear bumper 101. Therefore, the CPU 11 outputs the detection information of the obstacle detection sensor 2d to the composite image creation circuit 13 and the audio output circuit 14. At this time, the composite image creation circuit 13 includes a linear symbol S1 indicating a position on the road surface equal to the detection distance L1 from the obstacle detection sensor 2d to the detection target vehicle 200, and the detection target detected by the obstacle detection sensor 2d. A symbol S3 such as an enclosing line indicating a region surrounding a detection position of an obstacle in a plane standing upright from the position on the road surface equal to the distance L1 to the vehicle 200 and perpendicular to the road surface, and a distance standard Symbol S11 and symbols S21 to S23 such as encircling lines surrounding the detection region (hatched portion in the figure), and these symbols S1, S3, S11, S21 to S23 are superimposed on the captured image G1. And displayed on the monitor screen 4a. Also, the voice output circuit 14 synthesizes a voice message indicating at which part the obstacle is detected, and outputs the voice message from the speaker 5. Thus, only when there is an obstacle in the expected movement range X1, by displaying a symbol indicating detection information or outputting a warning by voice, it is possible to prevent an unnecessary warning from being issued to the driver, Reliable notification can be performed.
[0033]
By the way, in this embodiment, for example, as shown in FIG. 8A, the composite image creation circuit 13 moves from the position on the road surface equal to the distance L1 to the detection target vehicle 200 detected by the obstacle detection sensor 2d to the road surface. When a symbol S3 such as a surrounding line that indicates an area surrounding an obstacle detection position in a plane that stands vertically with respect to the obstacle is created, and the symbol S3 is superimposed on the captured image G1 and displayed, 9, the portion surrounded by the symbol S3 of the captured image G1 may be enlarged and displayed on the monitor screen 4a. Since the obstacle is enlarged and displayed, the obstacle can be easily confirmed.
[0034]
Note that the shape of each symbol S1... Is not limited to the above shape, and any shape of symbol may be used as long as it can display detection information about an obstacle.
