【発明の詳細な説明】 乗物用光学的後方死角視野の感知装置 本発明は自動車又は類似物用の光学的後方死角視野の感知装置に関する。[Detailed description of the invention] Optical rear blind spot sensing device for vehicles The present invention relates to an optical rear blind spot sensing device for a motor vehicle or the like.

本発明の目的は、道路規則に準拠した既設の付属部品を変更しないで運転者に付 加的の吟味手段を提供して、内・外部バックミラーでは感知できないすぐ側方の 障害物を信頼性のある方法で標示することである。The purpose of the present invention is to attach the existing accessory parts to the driver without changing them in accordance with the road regulations. Provides an additional means of examining areas immediately to the side that cannot be detected by internal or external rearview mirrors. The goal is to mark obstacles in a reliable manner.

従来、乗物の運転者の後方視野全体をカバーするためにフェンダ−或はドアに設 けた内部バックミラーが使用されていた。運転者は主として運転に注意を払いな がら同時に数個の装置を観察し、前方の障害物と計器盤のメータを観察しなけれ ばならなかった。しかし運転者が走行道路を変え、或は他の乗物を追抜く時に彼 の頭の向きを変え或は窓に寄りかからない限りは（このような挙動をすることは 大任の場合不可能であるが）、該乗物に検知装置が設けられていないので、接近 した障害物があるのに気付いで驚かされない訳には行かない。上記は殊に乗物が 高速道路を高速運転中は多くの事故の原因となっていた。乗物の後方視野を見る ためにバックミラーの代りにＴＶカメラを設けても上記の問題の完全な解決とは ならない。Conventionally, a vehicle was installed on the fender or door to cover the driver's entire rear field of view. A large internal rearview mirror was used. Drivers should mainly pay attention to driving. You must observe several devices at the same time, as well as obstacles in front of you and the meters on the instrument panel. I had to. However, when a driver changes roads or passes another vehicle, he Unless you change the direction of your head or lean against the window (this behavior will not occur). (which is impossible in the case of Dainin), since the vehicle is not equipped with a detection device, I can't help but be surprised when I notice that there are obstacles. The above is especially true for vehicles. Driving at high speeds on expressways has been the cause of many accidents. See the rear view of the vehicle Even if a TV camera is installed instead of a rearview mirror, it will not completely solve the above problem. No.

従来の刊公物では追抜き乗物の検知は最短及び最大反射距離間の危険領域内で音 響、光学的又は其他の波動を発信することにより行なっていた。」二記の危険領 域は走行方向に直角な２線間に存在する。従ってこの検知は道路の外側、巡回道 路に近接した道路に存在する障害物を考慮に入れて行なわれ、隣接道路を走行す る障害物以外のものも検知して了う。In conventional publications, the detection of overtaking vehicles is based on sound within the danger zone between the shortest and maximum reflection distances. This was done by transmitting acoustic, optical, or other waves. ” Two Dangerous Territories The area exists between two lines perpendicular to the direction of travel. Therefore, this detection is performed on the outside of the road, on the patrol road. This is done by taking into account obstacles that exist on roads close to the road, and when driving on adjacent roads. It is possible to detect objects other than obstacles.
