Description

【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】本発明は、人や貨物を輸送する車両のための後方視界表示装置に関する。 The present invention relates, on the rear view display device for a vehicle to transport people and cargo.

【0002】 [0002]

【従来の技術】最も多く用いられている車両である乗用車は、人と貨物を輸送するため、一般に前部から後部へと向かう順に、動力機関を収納する機関室、人を収納する車室、貨物を収納する荷室をもつ。 BACKGROUND OF THE INVENTION most is used vehicle passenger for the transport of people and goods, in order toward generally from the front to the rear, the engine room for accommodating the power engine, passenger compartment for accommodating a person, with a luggage compartment that houses the cargo. 運転者は車室内前部よりに位置し、運転時に前部窓を通して機関室越しに前方視界を得、後部窓を通して荷室越しに後方視界を得る。 The driver is located from the vehicle interior front, to obtain a front view of the engine compartment over through the front window during operation, obtain a rear view in luggage compartment over through the rear window. 一般に前方視界より後方視界の方が狭く、これを、 Generally narrow towards the rear view from the front view, this,
前方視界より後方視界の方が死角が大きいという。 That towards the rear view from the front field of vision is a large blind spot.

【0003】近年、車両の造型は、走行時の空気抵抗を低減することを考慮したものが増えてきている。 [0003] In recent years, the molding of the vehicle, has been increasing that in consideration of the fact that to reduce the air resistance during running. 空気抵抗の低減のためには車室の高さが低い方がよく、かつ荷室の高さが高い方がよい。 For the air resistance reduction may better low height of the cabin, and it is the higher the height of the luggage compartment. 従って、車室の高さが低く、 Therefore, lower the height of the cabin,
かつ荷室の高さが高くなる傾向がある。 And there is a tendency that the height of the luggage compartment is increased. このため、後部窓が小さくなり、もともと大きくない後方視界が狭く、 Therefore, the rear window is reduced, narrow rear view not originally large,
つまり後方視界の死角が大きくなり、運転時の後方視界の確保が十分でなかった。 That blind spot of the rear view is increased, securing rearward visibility during operation it is not sufficient.

【0004】また、乗用車以外にも、バスやトラックなどの一般の車両でも運転時の後方視界の確保が十分でなかった。 [0004] Also, in addition to passenger cars, ensuring rearward visibility at the time of operation in general of the vehicle, such as buses and trucks it was not enough.

【0005】車両の後方視界の映像をテレビカメラにより検出し、ルームミラー位置に設けた表示部に、後部窓を通して得られる通常後方視界と後部窓より下方の通常死角になる後方視界とを切り換えて表示する装置が特開昭58−209635号公報に記載されている。 [0005] The image of the rear view of the vehicle detected by the television camera, the display portion provided in the rearview mirror position, switching between rearward visibility consisting ordinary rear view and a rear window which is obtained through the rear window to the normal blind spot below device for display is described in JP-a-58-209635. しかしながら、この装置では通常後方視界と死角後方視界とを切り換えて表示するため同時に両者を見ることができず、広い視界が得られたとは言いがたい。 However, it is not possible to see both at the same time to display switching between normal rear view and blind spot rearward visibility with this device, it is difficult to say the wide field of view is obtained. また、通常後退時は運転者はルームミラーを見ながらではなく、後方を振り向き、後部窓を通して後方を見て視界を得る。 Also, during normal retracting the driver is not looking at the rearview mirror, turning backwards, to obtain a field of view looking at the rear through the rear window. 従って、この装置のようにルームミラー位置に表示部を設けた装置では、最も広い後方視界を必要とする後退時に何の効果もない。 Thus, the apparatus having a display unit to the room mirror position as in this apparatus, no effect upon retraction which requires the widest rear view.

【0006】 [0006]

【発明が解決しようとする課題】本発明は、運転時に十分な後方視界を確保できる車両用後方視界表示装置を提供するものである。 [0008] The present invention is to provide a rear view display device for a vehicle capable of securing a sufficient rearward visibility during operation.

【0007】 [0007]

【課題を解決するための手段】本発明は、車両後方の画像を入力する画像入力装置、および、後部座席背もたれ部に内蔵された前記画像入力装置からの画像を表示する表示装置を具備することを特徴とする車両用後方視界表示装置、ならびに、車両後方の画像を入力する画像入力装置、および、前記画像入力装置からの画像を後部座席背もたれ部に投射する投射装置を具備することを特徴とする車両用後方視界表示装置である。 Means for Solving the Problems The present invention relates to an image input device for inputting an image behind the vehicle, and be provided with a display device for displaying an image from the image input device incorporated in the rear seat backrest rear view display device for a vehicle according to claim, and an image input device for inputting an image behind the vehicle, and a feature by including a projection device that projects an image from the image input device to the rear seat backrest it is a rear view display device for a vehicle to be. 画像入力装置からの画像信号を処理し、画像の距離抽出、画像分解、画像合成を行う機能をもつ信号処理装置を具備することは好ましい。 Processing the image signal from the image input device, the distance of the image-extraction, image degradation, it is preferable having a signal processing device having a function of performing image synthesis.
