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（運転者）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、運転者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 side and rear of the vehicle, which cannot be directly seen by the driver, are indirectly visually recognized by using a mirror-type display means such as a side mirror (door mirror) or a rear-view mirror. We make it possible to drive appropriately according to the situation.

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、運転者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 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、運転者がミラー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、運転者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, Patent Document 2 focuses on the driver by indirectly viewing the image of the display device in the vehicle interior through the mirror and increasing the distance from the driver to the display surface of the display device. A method for shortening the adjustment time is disclosed.

特開平０７−２２３４８７号公報Japanese Unexamined Patent Publication No. 07-223487 特開２０１６−０４０１４０号公報Japanese Unexamined Patent Publication No. 2016-040140

しかしながら、特許文献２においては、サイドミラー等に替えて車室内に複数の表示装置を設け、ミラーを介して各表示装置の画像を視認することになるため、各表示装置に対する運転者のアイポイントとミラーとの距離、ミラーと表示装置との距離等が異なる。このため、特許文献２の車両用周辺表示装置では、複数の表示装置の各々に表示される画像の大きさが異なり、視認性が悪いという問題があった。 However, in Patent Document 2, a plurality of display devices are provided in the vehicle interior instead of the side mirrors and the like, and the image of each display device is visually recognized through the mirror. Therefore, the driver's eye point for each display device. The distance between the mirror and the mirror, the distance between the mirror and the display device, etc. are different. Therefore, the vehicle peripheral display device of Patent Document 2 has a problem that the size of the image displayed on each of the plurality of display devices is different and the visibility is poor.

本発明は、上記事情に鑑み、従来と比較し、視認性に優れた車両用周辺表示装置を提供することを目的とする。 In view of the above circumstances, an object of the present invention is to provide a vehicle peripheral display device having excellent visibility as compared with the conventional one.

上記の課題を解決するために、請求項１記載の車両用周辺表示装置は、車両用周辺領域を撮像する少なくとも２つの撮像手段と、車室内に配置され、少なくとも２つの撮像手段で撮像された画像をそれぞれ表示する少なくとも２つの表示手段とを備える車両用周辺表示装置において、前記表示手段は、表示部品と、光学部品と、少なくとも前記表示部品を保持する保持手段と、前記表示部品を前記保持手段に位置決め固定する抜け止め部材と、を備え、前記保持手段には、上下方向に交差する横方向に延び、前記表示部品の上端と下端とが前記横方向から各別に差し込まれることで、前記表示部品を前記光学部品に対して所定の位置で保持する複数の係止溝が形成され、前記抜け止め部材は、前記表示部品の側端部に取り付けられ、前記表示部品が前記係止溝から引き抜けないように前記係止溝に差し込まれ、前記光学部品と前記表示部品は、車両の運転者に対し、複数の表示手段でそれぞれ表示される画像が同一の大きさで視認されるように構成されていることを特徴とする。 In order to solve the above problems, the vehicle peripheral display device according to claim 1 is arranged with at least two imaging means for imaging the vehicle peripheral region and at least two imaging means arranged in the vehicle interior. In a vehicle peripheral display device including at least two display means for displaying an image, the display means includes a display component, an optical component, a holding means for holding at least the display component, and holding the display component. A retaining member for positioning and fixing to the means is provided, and the holding means extends in the lateral direction intersecting in the vertical direction, and the upper end and the lower end of the display component are separately inserted from the lateral direction. A plurality of locking grooves for holding the display component at a predetermined position with respect to the optical component are formed, the retaining member is attached to a side end portion of the display component, and the display component is removed from the locking groove. The optical component and the display component are inserted into the locking groove so as not to be pulled out so that the image displayed by the plurality of display means can be visually recognized by the driver of the vehicle in the same size. It is characterized by being configured.

この発明においては、少なくとも２つの撮像手段で撮像した車両用周辺の画像をそれぞれ表示する少なくとも２つの表示手段を表示部品と光学部品で構成されているため、各表示手段で表示される画像の大きさを表示部品と光学部品の調整によって任意に変えることが可能になる。 In the present invention, since at least two display means for displaying images of the surroundings for the vehicle captured by at least two imaging means are composed of a display component and an optical component, the size of the image displayed by each display means is large. It is possible to change the image arbitrarily by adjusting the display component and the optical component.

これにより、例えば、運転者から離れた表示手段で表示される画像を大きく調整するなどして、複数の表示手段でそれぞれ表示される画像を同一の大きさにすることができ、運転者が視認した状態での各々の表示手段の画像の大きさを同一にすることが可能になる。 As a result, for example, the image displayed by the display means away from the driver can be greatly adjusted so that the images displayed by the plurality of display means have the same size, and the driver can visually recognize the image. It is possible to make the size of the image of each display means the same in this state.

よって、従来と比較し、運転者の視認性を向上させることができ、目の疲労や視認性の低減などが生じにくい快適な運転操作環境を実現することが可能になる。 Therefore, the visibility of the driver can be improved as compared with the conventional case, and it is possible to realize a comfortable driving operation environment in which eye fatigue and reduction of visibility are less likely to occur.

As a condition for visually recognizing the images of the plurality of display means with the same size, the distance between the concave mirror and the monitor is set.

この発明においては、運転者に対して相対位置が異なる各表示手段の凹面鏡とモニタとの距離をそれぞれ個別に設定することによって、各表示手段で表示される画像の大きさを任意に設定することができる。これにより、容易に運転者が視認した状態での各々の表示手段の画像の大きさを同一にすることができる。 In the present invention, the size of the image displayed by each display means can be arbitrarily set by individually setting the distance between the concave mirror and the monitor of each display means having different relative positions with respect to the driver. Can be done. As a result, the size of the image of each display means in the state visually recognized by the driver can be easily made the same.

請求項３記載の車両用周辺表示装置は、請求項１記載の車両用周辺表示装置において、前記表示部品は前記撮像手段で撮像したものを表示するモニタであり、前記光学部品は凹面鏡であり、複数の表示手段のそれぞれの画像を同一の大きさで視認させるための条件として、前記凹面鏡に対する前記モニタの角度が設定されていることを特徴とする。 The vehicle peripheral display device according to claim 3 is the vehicle peripheral display device according to claim 1, wherein the display component is a monitor that displays an image captured by the imaging means, and the optical component is a concave mirror.

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, the smaller the distance, the larger the image displayed by the visual recognition units 7 and 29. 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. Can be done.

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.

したがって、本実施形態の車両用周辺表示装置Ａにおいては、２つの撮像手段で撮像した車両１００周辺の画像をそれぞれ表示する２つの表示手段３、２５が、モニタなどの表示部（表示部品）５、２７と平面鏡８ａや凹面鏡８ｂ、３０ａの鏡体（光学部品）８、３０とで構成されているため、各表示手段３、２５で表示される画像の大きさを表示部品５、２７と光学部品８、３０の調整によって任意に変えることが可能になる。 Therefore, in the vehicle peripheral display device A of the present embodiment, the two display means 3 and 25 for displaying the images around the vehicle 100 captured by the two imaging means are display units (display components) 5 such as a monitor. , 27 and the mirror bodies (optical components) 8 and 30 of the plane mirrors 8a and the concave mirrors 8b and 30a. It can be changed arbitrarily by adjusting the parts 8 and 30.

これにより、例えば、運転者Ｍから離れた表示手段３、２５で表示される画像を大きく調整するなどして、複数の表示手段３、２５でそれぞれ表示される画像を同一の大きさにすることができ、運転者Ｍが視認した状態での各々の表示手段３、２５の画像の大きさを同一にすることが可能になる。 As a result, for example, the images displayed by the display means 3 and 25 away from the driver M can be greatly adjusted so that the images displayed by the plurality of display means 3 and 25 have the same size. This makes it possible to make the size of the images of the display means 3 and 25 in the state visually recognized by the driver M the same.

よって、本実施形態の車両用周辺表示装置Ａによれば、運転者Ｍが視認する各表示手段３、２５の画像の大きさを同一にすることができるため、従来と比較し、運転者Ｍの視認性を向上させることができ、目の疲労や視認性の低減などが生じにくい快適な運転操作環境を実現することが可能になる。 Therefore, according to the vehicle peripheral display device A of the present embodiment, the size of the images of the display means 3 and 25 visually recognized by the driver M can be made the same, so that the driver M can compare with the conventional one. It is possible to improve the visibility of the vehicle and realize a comfortable driving operation environment in which eye fatigue and reduction of visibility are less likely to occur.

また、本実施形態の車両用周辺表示装置Ａにおいては、運転者Ｍに対して相対位置が異なる各表示手段３、２５の凹面鏡８ｂ、３０ａと表示部（モニタ）５、２７との距離をそれぞれ個別に設定することによって、各表示手段３、２５で表示される画像の大きさを任意に設定することができる。これにより、容易に運転者Ｍが視認した状態での各々の表示手段３、２５の画像の大きさを同一にすることができる。 Further, in the vehicle peripheral display device A of the present embodiment, the distances between the concave mirrors 8b and 30a of the display means 3 and 25 having different relative positions to the driver M and the display units (monitors) 5 and 27, respectively, are set. By setting them individually, the size of the image displayed by each of the display means 3 and 25 can be arbitrarily set. As a result, the size of the images of the display means 3 and 25 in the state visually recognized by the driver M can be easily made the same.

さらに、運転者Ｍに対して相対位置が異なる各表示手段３、２５の凹面鏡８ｂ、３０ａと表示部５、２７の相対角度をそれぞれ個別に設定することによって、各表示手段３、２５で表示される画像の大きさを任意に設定することができる。これにより、容易に運転者Ｍが視認した状態での各々の表示手段３、２５の画像の大きさを同一にすることができる。 Further, by individually setting the relative angles of the concave mirrors 8b and 30a of the display means 3 and 25 having different relative positions to the driver M and the display units 5 and 27, the images are displayed on the display means 3 and 25. The size of the image can be set arbitrarily. As a result, the size of the images of the display means 3 and 25 in the state visually recognized by the driver M can be easily made the same.
