Description

本発明は、サイドミラーなどに替えて車両の周囲状況を運転者（ドライバー）に表示する車両用周辺表示装置に関する。 The present invention relates to a vehicle peripheral display device that displays the surrounding condition of a vehicle to a driver (driver) instead of a side mirror or the like.

従来、自動車などの車両においては、ドライバーが直接視認できない車両の側方や後方をサイドミラー（ドアミラー）やバックミラーなどのミラー方式の表示手段を用いて間接視認することで、車両の周囲の状況に合致した適切な運転が行えるようにしている。 Conventionally, in a vehicle such as an automobile, the situation around the vehicle is indirectly visually recognized by using a mirror-type display means such as a side mirror (door mirror) or a rearview mirror to visually recognize the side or rear of the vehicle that the driver cannot directly see. Appropriate operation that matches the above is possible.

一方、例えばミラー方式の間接的な表示手段では後方の視界を確保しにくいバスなどの車両においては、車両のバックビューをテレビカメラで撮影しこれを車室内のモニタで表示する手法も実用化されている。 On the other hand, for example, in a vehicle such as a bus where it is difficult to secure a rear view with a mirror-type indirect display means, a method of capturing the back view of the vehicle with a TV camera and displaying it on a monitor in the vehicle interior has also been put into practical use. ing.

さらに、特許文献１には、サイドミラーに替え、撮像手段及び表示装置（画像表示手段）を用いて車両の周辺状況を表示する車両用周辺表示装置が開示されている。しかしながら、特許文献１に記載の車両用周辺表示装置においては、ドライバーが直接的に車室内の表示装置のモニタ画像を見ることになる。このため、運転中、遠距離の対象物と近距離の対象物(モニタ画像)の２点間で眼の切り替えを行うことになる。この２点間の視線の切替動作を行う際には、運転者の焦点調整時間が長くなり、視線の切替を繰り返し継続すると、目の疲労や視認性の低減などが生じるおそれがある。 Further, Patent Document 1 discloses a vehicle peripheral display device that displays a vehicle peripheral situation by using an imaging means and a display device (image display means) instead of a side mirror. However, in the vehicle peripheral display device described in Patent Document 1, the driver directly sees the monitor image of the display device in the vehicle interior. Therefore, during driving, the eyes are switched between two points, a long-distance object and a short-distance object (monitor image). When the line-of-sight switching operation between the two points is performed, the driver's focus adjustment time becomes long, and if the line-of-sight switching is repeated and continued, eye fatigue and reduced visibility may occur.

これに対し、特許文献２には、ドライバーがミラー（鏡体）を介して車室内の表示装置の画像を間接的に視認するようにし、ドライバーから表示装置の表示面までの距離を長くすることで焦点調整時間を短くする手法が開示されている。 On the other hand, in Patent Document 2, the driver indirectly visually recognizes the image of the display device in the vehicle interior through the mirror (mirror body), and the distance from the driver to the display surface of the display device is increased. Discloses a method for shortening the focus adjustment time.

しかしながら、特許文献２に記載の車両用周辺表示装置は、モニタを含む表示装置とミラーが別体で、車両に対し別々に取り付ける必要がある。このため、取付け作業性が悪い。 However, in the vehicle peripheral display device described in Patent Document 2, the display device including the monitor and the mirror are separate bodies, and it is necessary to separately attach them to the vehicle. Therefore, the mounting workability is poor.

これに対し、特許文献３には、モニタとミラーを内部に収納して表示ユニットを構成し、表示ユニットを車両に搭載するようにした車両用周辺表示装置が開示されている。 On the other hand, Patent Document 3 discloses a vehicle peripheral display device in which a monitor and a mirror are housed inside to form a display unit, and the display unit is mounted on a vehicle.

以下、図１から図１２を参照し、本発明の一実施形態に係る車両用周辺表示装置について説明する。ここで、本実施形態は、左右一対のサイドミラーに替え、撮像手段及び表示手段を用いて車両の周辺状況を表示する車両用周辺表示装置に関するものである。また、本実施形態では、車両用周辺表示装置を備える車両が左ハンドル車であるものとして説明を行うが、勿論、この点、特に限定を必要とするものではない。 Hereinafter, a vehicle peripheral display device according to an embodiment of the present invention will be described with reference to FIGS. 1 to 12. Here, the present embodiment relates to a vehicle peripheral display device that displays the peripheral situation of the vehicle by using an imaging means and a display means instead of the pair of left and right side mirrors. Further, in the present embodiment, the vehicle provided with the vehicle peripheral display device will be described as a left-handle vehicle, but of course, this point is not particularly limited.

本実施形態の車両用周辺表示装置Ａは、図１から図３に示すように、ＤＲ側（ドライバー（運転者）側／左側）の一方のサイドミラーに替えて設けられるＤＲ側の車両周辺表示手段１と、ＡＳ側（アシスタント側／右側）の他方のサイドミラーに替えて設けられるＡＳ側の車両周辺表示手段２の左右一対の車両周辺表示手段１、２を備えて構成されている。 As shown in FIGS. 1 to 3, the vehicle peripheral display device A of the present embodiment is provided to replace one side mirror on the DR side (driver (driver) side / left side) with the vehicle peripheral display on the DR side. The means 1 and a pair of left and right vehicle peripheral display means 1 and 2 of the AS side vehicle peripheral display means 2 provided in place of the other side mirror on the AS side (assistant side / right side) are provided.

ＤＲ側の車両周辺表示手段１は、図１及び図２に示すように、車両１００の左側の周辺状況を撮像するＤＲ側の撮像手段（不図示）と、ＤＲ側の撮像手段で取得された画像信号を受けて画像を表示するＤＲ側の表示手段３とを備えている。 As shown in FIGS. 1 and 2, the vehicle peripheral display means 1 on the DR side was acquired by an image pickup means (not shown) on the DR side that images the surrounding situation on the left side of the vehicle 100 and an image pickup means on the DR side. It is provided with a display means 3 on the DR side that receives an image signal and displays an image.

ＤＲ側の撮像手段は、例えば、ＣＣＤカメラなどであり、車両１００の左側側部の適正な周辺領域を撮像できるように車両１００の左側側面の前方側に取り付けられている。 The imaging means on the DR side is, for example, a CCD camera or the like, and is attached to the front side of the left side surface of the vehicle 100 so that an appropriate peripheral region of the left side portion of the vehicle 100 can be imaged.

ＤＲ側の表示手段３は、図１、図２、図４〜図６に示すように、外殻をなす中空状の筐体４と、ＤＲ側の撮像手段から画像信号を受けて画像を表示するモニタなどの表示部（表示部品）５と、筐体４に形成された開口部にアクリル板などの透明部材６を取り付けてなり、運転者Ｍが表示部５で表示された画像を視認させる視認部７と、表示部５で表示された画像を反射して視認部７で表示させるための鏡体（反射鏡、光学部品）８とを備えて構成されている。 As shown in FIGS. 1, 2, 4 to 6, the display means 3 on the DR side receives an image signal from the hollow housing 4 forming the outer shell and the image pickup means on the DR side and displays an image. A transparent member 6 such as an acrylic plate is attached to a display unit (display component) 5 such as a monitor and an opening formed in the housing 4, so that the driver M can visually recognize the image displayed on the display unit 5. It is configured to include a viewing unit 7 and a mirror body (reflecting mirror, optical component) 8 for reflecting an image displayed on the display unit 5 and displaying it on the viewing unit 7.

表示部５と鏡体８が筐体４の内部に設けられ、ＤＲ側の表示手段３がユニット化されている。すなわち、筐体４と表示部５と鏡体８とを備えてＤＲ側の表示ユニットＵ１が構成されている。なお、本実施形態の表示ユニットＵ１の構成要素である筐体４は、表示部５と鏡体８、さらには後述の保持手段１０（２０）を一体に保持することが可能であればよく、例えば枠体であってもよい。 The display unit 5 and the mirror body 8 are provided inside the housing 4, and the display means 3 on the DR side is unitized. That is, the display unit U1 on the DR side is configured by including the housing 4, the display unit 5, and the mirror body 8. The housing 4, which is a component of the display unit U1 of the present embodiment, may be capable of integrally holding the display unit 5, the mirror body 8, and the holding means 10 (20) described later. For example, it may be a frame.

ＤＲ側の視認部７は、筐体４の所定位置に外面から内面に貫通形成された方形状などの開口部４ａを閉塞するように、アクリル板等の透明部材６を筐体４に取り付けて構成され、ダッシュボード１０１の左端側（インパネ：インテリアパネルの左側端部近傍）に配設されている。 The viewing portion 7 on the DR side attaches a transparent member 6 such as an acrylic plate to the housing 4 so as to close the opening 4a such as a square formed through the outer surface to the inner surface at a predetermined position of the housing 4. It is configured and is arranged on the left end side of the dashboard 101 (instrument panel: near the left end portion of the interior panel).

また、透明部材６の外面には、運転者Ｍが視認する領域を囲繞するように環状にスポンジなどの干渉保護材９が一体に取り付けられている。なお、透明部材６の表面は、反射および汚れを防止するための表面処理が施されている。 Further, an interference protective material 9 such as a sponge is integrally attached to the outer surface of the transparent member 6 so as to surround the area visually recognized by the driver M. The surface of the transparent member 6 is subjected to surface treatment to prevent reflection and stains.

そして、ＤＲ側の表示手段３を車両１００のダッシュボード１０１の内部の所定位置に取り付けた状態で、視認部７がダッシュボード１０１に形成した開口部１０１ａに配されるように構成されている。 Then, with the display means 3 on the DR side attached to a predetermined position inside the dashboard 101 of the vehicle 100, the viewing unit 7 is configured to be arranged in the opening 101a formed in the dashboard 101.

このとき、ダッシュボード１０１の裏面側に干渉保護材９が当接し、ダッシュボード１０１と視認部７の透明部材６の間に挟まって介装される。
これにより、干渉保護材９によって表示ユニットＵ１の取付けガタの発生を防止でき、さらに透明部材６の側方から視認部７、さらに筐体４の内部に余計な光が入り込むことを阻止して視認性が低下することを防止できる。 At this time, the interference protective material 9 comes into contact with the back surface side of the dashboard 101, and is sandwiched between the dashboard 101 and the transparent member 6 of the visual recognition portion 7.
As a result, the interference protective material 9 can prevent the occurrence of play in the mounting of the display unit U1, and further prevent extra light from entering the viewing portion 7 and the housing 4 from the side of the transparent member 6 for viewing. It is possible to prevent deterioration of sex.

ＤＲ側の表示手段３は、鏡体８として、平面鏡８ａと凹面鏡８ｂの二種の反射鏡が具備されている。

ここで、ＤＲ側とＡＳ側の左右の表示手段３、２５の視認部７、２９で表示される画像の大きさを同じにする条件の一例について具体的に説明する。 Here, an example of a condition in which the sizes of the images displayed by the visual recognition units 7 and 29 of the left and right display means 3 and 25 on the DR side and the AS side are the same will be specifically described.

第一に、図１１に示すように、各表示手段３、２５の凹面鏡８ｂ、３０ａと表示部５、２７の間の距離を設定することで、左右の視認部７、２９で表示されて運転者Ｍが視認する画像の大きさを同一にすることができる。 First, as shown in FIG. 11, by setting the distance between the concave mirrors 8b and 30a of the display means 3 and 25 and the display units 5 and 27, the left and right visual units 7 and 29 display and operate. The size of the image visually recognized by the person M can be made the same.

例えば、距離が小さくなるほど視認部７、２９で表示される画像が拡大するため、図１１（ａ）に示すように、ＤＲ側の表示手段３の表示部５と平面鏡８ａの距離を１１５ｍｍ、平面鏡８ａと凹面鏡８ｂの距離を１４５．９ｍｍとし、図１１（ｂ）に示すように、ＡＳ側の表示手段２５の表示部２７と凹面鏡３０ａの距離を１６２．９ｍｍとすれば、身長が１８０ｃｍの運転者ＭがＤＲ側の視認部７、ＡＳ側の視認部２９でそれぞれ表示される画像の大きさを同じにすることができる。 For example, as the distance becomes smaller, the images displayed by the visual recognition units 7 and 29 are enlarged. Therefore, as shown in FIG. 11A, the distance between the display unit 5 of the display means 3 on the DR side and the plane mirror 8a is 115 mm, and the plane mirror. If the distance between the 8a and the concave mirror 8b is 145.9 mm and the distance between the display unit 27 of the display means 25 on the AS side and the concave mirror 30a is 162.9 mm as shown in FIG. 11 (b), the operation with a height of 180 cm is performed. The size of the image displayed by the person M on the viewing unit 7 on the DR side and the viewing unit 29 on the AS side can be made the same.

第二に、図１２に示すように、表示部５、２７の角度を設定することで、左右の視認部７、２９で表示されて運転者Ｍが視認する画像の大きさを同一にすることができる。 Secondly, as shown in FIG. 12, by setting the angles of the display units 5 and 27, the sizes of the images displayed by the left and right visual units 7 and 29 and visually recognized by the driver M are made the same.

すなわち、図１２（ａ）、（ｂ）に示すように、凹面鏡８ｂ、３０ａの中心と凹面鏡８ｂ、３０ａの曲率中心とを結ぶ光軸Ｐ１と、凹面鏡８ｂ、３０ａの中心と表示部５、２７または平面鏡８ａの中心とを結ぶ光軸Ｐ２の角度θを設定する。この角度θが大きくなるほど画像は拡大するため、ＤＲ側の表示手段３の表示部５の角度θと、ＡＳ側の表示手段２５の表示部２７の角度θをそれぞれ調整すれば、身長が１８０ｃｍの運転者ＭがＤＲ側の視認部７、ＡＳ側の視認部２９でそれぞれ表示される画像の大きさを同じにすることができる。 That is, as shown in FIGS. 12 (a) and 12 (b), the optical axis P1 connecting the center of the concave mirrors 8b and 30a and the center of curvature of the concave mirrors 8b and 30a, the center of the concave mirrors 8b and 30a, and the display units 5 and 27. Alternatively, the angle θ of the optical axis P2 connecting to the center of the plane mirror 8a is set. The larger the angle θ, the larger the image. Therefore, if the angle θ of the display unit 5 of the display means 3 on the DR side and the angle θ of the display unit 27 of the display means 25 on the AS side are adjusted, the height becomes 180 cm. The size of the image displayed by the driver M on the viewing unit 7 on the DR side and the viewing unit 29 on the AS side can be made the same.

第三に、図１１に示すように、各表示手段３、２５の凹面鏡８ｂ、３０ａの曲率を適宜設定することで、左右の視認部７、２９で表示されて運転者Ｍが視認する画像の大きさを同一にすることができる。 Thirdly, as shown in FIG. 11, by appropriately setting the curvatures of the concave mirrors 8b and 30a of the display means 3 and 25, the image displayed by the left and right visual recognition units 7 and 29 and visually recognized by the driver M. The size can be the same.

例えば、図１１（ａ）に示すように、ＤＲ側の表示手段３の凹面鏡８ｂの曲率をＲ３０００、図１１（ｂ）に示すように、ＡＳ側の表示手段２５の凹面鏡３０ａの曲率をＲ１４００とすることで、身長が１８０ｃｍの運転者ＭがＤＲ側の視認部７、ＡＳ側の視認部２９でそれぞれ表示される画像の大きさを同じにすることができる。 For example, as shown in FIG. 11A, the curvature of the concave mirror 8b of the display means 3 on the DR side is R3000, and as shown in FIG. 11B, the curvature of the concave mirror 30a of the display means 25 on the AS side is R1400. By doing so, the driver M having a height of 180 cm can make the size of the image displayed by the viewing unit 7 on the DR side and the viewing unit 29 on the AS side the same.

一方、本実施形態の車両用周辺表示装置Ａにおいては、モニタなどの表示部５と鏡体８を保持手段１０で一体に保持し、この状態の保持手段１０を表示ユニットＵ１の筐体４に取り付け、さらに表示ユニットＵ１を車両１００に取り付けることで、容易に車両用周辺表示装置Ａの表示部５と鏡体８を車両１００の所定位置に取り付けることができる。すなわち、従来よりも取付け作業性を向上させることが可能になる。 On the other hand, in the vehicle peripheral display device A of the present embodiment, the display unit 5 such as a monitor and the mirror body 8 are integrally held by the holding means 10, and the holding means 10 in this state is housed in the housing 4 of the display unit U1. By attaching the display unit U1 to the vehicle 100, the display unit 5 and the mirror body 8 of the vehicle peripheral display device A can be easily attached to a predetermined position of the vehicle 100. That is, it is possible to improve the mounting workability as compared with the conventional case.
