Description

情報表示装置Information display device
　本発明は、自動車や電車や航空機等の人を乗せて移動する、いわゆる、乗り物のフロントガラスに画像を投影する情報表示装置に関する。 The present invention relates to an information display device for projecting an image on a windshield of a vehicle, on which a person such as an automobile, a train or an aircraft moves.
　自動車のフロントガラスに映像光を投写して虚像を形成し、地図や走行ルートを含むナビゲーション情報、渋滞情報などの交通情報、さらには、燃料残量や冷却水温度等の自動車情報を表示する、いわゆる、ヘッドアップディスプレイ（ＨＵＤ：Ｈｅａｄ－Ｕｐ－Ｄｉｓｐｌａｙ）装置は、例えば、以下の特許文献１により既に知られており、ＨＵＤ装置本体は運転者の座席前方のステアリングとウインドガラスの間に配置される。 Projecting image light on the windshield of a car to form a virtual image, displaying navigation information including maps and travel routes, traffic information such as traffic jam information, and car information such as remaining fuel and coolant temperature, A so-called head-up display (HUD) device is already known from, for example, Patent Document 1 below, and the HUD device main body is disposed between a steering wheel in front of a driver's seat and a window glass. The
　この種の情報表示装置においては、運転者が情報を認識し易くすることを目的として、運転者の視認位置に応じて複数の位置に虚像を形成すること、すなわち虚像の形成する距離を運転者の視認位置に合わせることが求められている。このため、例えば以下の特許文献２にも開示されるように、運転者から遠方（遠距離）および近傍（近距離）のそれぞれに像を形成するもの（いわゆる、３Ｄ地図）がある。 In this type of information display device, for the purpose of facilitating recognition of information by the driver, a virtual image is formed at a plurality of positions according to the driver's visual recognition position, that is, the distance at which the virtual image is formed is determined by the driver. It is required to be matched with the viewing position. For this reason, for example, as disclosed in Patent Document 2 below, there is an apparatus (so-called 3D map) that forms an image at a distance (far distance) and a vicinity (short distance) from the driver.

　上記の従来技術によるＨＵＤ装置では、自動車のフロントガラスに映像光を投写して虚像を形成してドライバーに対して各種の情報を提供する。しかしながら、上述した地図や走行ルートを含むナビゲーション情報を表示するナビゲーション機能は、予め車両内に搭載して使用されるＨＵＤ装置だけにとどまらず、例えば、スマートフォン（以下、単に「スマホ」とも言う）に代表される高性能の携帯端末装置にも搭載可能となっており、移動の際の利用者の位置情報や交通情報等との関連において、広く一般に利用されてきている。さらに、その一例として、当該スマホを、運転者の座席前方のステアリングとウインドガラスの間に配置して、いわゆる、ナビゲーション装置として利用する利用形態が既に知られて広く行われている。 In the above-described conventional HUD device, image light is projected on the windshield of an automobile to form a virtual image and provide various information to the driver. However, the navigation function for displaying the navigation information including the map and the driving route described above is not limited to the HUD device that is mounted in advance in the vehicle and used in, for example, a smartphone (hereinafter also simply referred to as “smartphone”). It can also be installed in a representative high-performance portable terminal device, and has been widely used in relation to user location information, traffic information, and the like during movement. Furthermore, as an example, a usage form in which the smartphone is used as a navigation device by arranging the smartphone between a steering wheel in front of the driver's seat and the window glass has been widely known.
　その一方において、上述したような携帯が可能なスマホの利用形態の拡大は、スマホによる弊害の増加にもつながっている。特に、スマホの画面を見ながら行動を行う、いわゆる、「ながらスマホ（携帯）」による各種の事故が数多く報告されており、特に、自動車の運転時における「ながらスマホ（携帯）」に起因する交通事故は、運転者のみならず歩行者等を巻き込んだ重大事故にもつながり、社会的にも大きな問題となっている。 On the other hand, the expansion of the usage forms of mobile phones that can be carried as described above also leads to an increase in harmful effects caused by smartphones. In particular, there have been many reports of various accidents caused by so-called “while smartphones (mobiles)” that act while looking at the screens of smartphones. Especially, traffic caused by “smartphones (mobiles)” when driving a car. Accidents have led to serious accidents involving not only drivers but also pedestrians, which has become a major social problem.

In addition, the following description shows the specific example of the content of this invention, This invention is not limited to these description, The person skilled in the art within the range of the technical idea disclosed by this specification. Various changes and modifications are possible.
　また、本発明を説明するための全図において、同一の機能を有するものは、同一の符号を付け、その繰り返しの説明は省略する場合がある。なお、以下には、本発明の実施の形態の説明に先立ち、本発明の特徴であるナビゲーション情報の表示位置について述べる。また、ナビゲーション機能を搭載した高性能の携帯端末装置としては、上述したスマホを代表として説明する。 In all the drawings for explaining the present invention, the same reference numerals are given to those having the same function, and repeated explanation thereof may be omitted. In the following, prior to the description of the embodiment of the present invention, the display position of navigation information, which is a feature of the present invention, will be described. As a high-performance portable terminal device equipped with a navigation function, the above-described smartphone will be described as a representative.
　図１（ａ）は、本発明の情報表示装置を搭載した自動車（乗り物）の上面図であり、自動車本体１０１の運転席前部には、被投影部材６としてのフロントガラスが存在する。なお、このフロントガラスは、自動車のタイプによって、車体に対する傾斜角度が異なる。さらに、発明者らは、最適な虚像光学系を実現するため、この曲率半径についても調査した。その結果、フロントガラスは、図１（ｂ）に示すように、自動車の接地面に対して平行な水平方向の曲率半径Ｒｈと、水平軸に対して直交する垂直方向の曲率半径Ｒｖとで異なり、ＲｈとＲｖは一般的には下記の関係がある。
　　　　　　　　　Ｒｈ＞Ｒｖ FIG. 1A is a top view of an automobile (vehicle) equipped with the information display device of the present invention, and a windshield as the projection member 6 exists in the front part of the driver seat of the automobile body 101. The windshield has a different inclination angle with respect to the vehicle body depending on the type of automobile. Furthermore, the inventors investigated the radius of curvature in order to realize an optimum virtual image optical system. As a result, as shown in FIG. 1B, the windshield differs in a horizontal radius of curvature Rh parallel to the ground contact surface of the automobile and a vertical radius of curvature Rv perpendicular to the horizontal axis. Rh and Rv generally have the following relationship.
Rh> Rv
　また、この曲率半径の違い、すなわち、Ｒｖに対するＲｈは、１．５倍から２．５倍の範囲にあるものが多いことも判明した。 It was also found that the difference in radius of curvature, that is, Rh relative to Rv is often in the range of 1.5 to 2.5 times.
　次に、発明者等はフロントガラスの傾斜角度についても市販品を調査した。その結果、車体タイプによっても異なるが、軽自動車や１Ｂｏｘタイプでは２０度～３０度、セダンタイプでは３０度～４０度、スポーツタイプでは４０度以上であった。 Next, the inventors investigated a commercial product for the inclination angle of the windshield. As a result, although it differs depending on the body type, it was 20 to 30 degrees for light cars and 1 Box type, 30 to 40 degrees for sedan type, and 40 degrees or more for sports type.
　＜高性能の携帯端末装置＞
　図２は、本発明の情報表示装置においてナビゲーション情報を提供する手段、すなわち、ナビゲーション機能を搭載した高性能の携帯端末装置であるスマホ２００の一例を示しており、その表示画面２１０には、地図やルートを含むナビゲーション情報が表示可能となっている。なお、図２の符号２２０は、当該装置の起動などを行うためのプッシュボタンを示している。 <High-performance portable terminal device>
FIG. 2 shows an example of a smartphone 200 that is a high-performance portable terminal device equipped with means for providing navigation information in the information display device of the present invention, that is, a navigation function. Navigation information including routes and routes can be displayed. 2 indicates a push button for starting up the apparatus.
　なお、この高性能の携帯端末装置であるスマホ２００は、後にも述べるが、ナビゲーション機能を搭載（可能）すると共に、その表示画像信号を、有線の接続端子を介して、または、Bluetooth（登録商標）やＷｉｆｉ等の無線によって外部（以下に述べる情報表示装置（ＨＵＤ装置）へ出力することが可能となっている。 As will be described later, the smartphone 200, which is a high-performance portable terminal device, is equipped with a navigation function (possible) and transmits its display image signal via a wired connection terminal or Bluetooth (registered trademark). ) Or WiFi, etc., can be output to the outside (information display device (HUD device) described below).
　さらに、図３は、本発明の情報表示装置を搭載した自動車の運転席からフロントガラス６を見た場合の概略図であり、図３（ａ）には、米国に代表される左ハンドルの場合の例を、図３（ｂ）には、日本に代表される右ハンドルの場合の例を示している。 Further, FIG. 3 is a schematic view when the windshield 6 is viewed from the driver's seat of the automobile equipped with the information display device of the present invention. FIG. 3 (a) shows the case of the left steering wheel represented by the United States. FIG. 3B shows an example of the case of a right handle represented by Japan.
　これらの図から明らかなように、ステアリング４３の前面のフロントガラス６の左端の近辺（または、右端の近辺）には、ＨＵＤの画像表示領域（エリア）が設けられている。 As is apparent from these drawings, an HUD image display area (area) is provided in the vicinity of the left end (or the vicinity of the right end) of the windshield 6 on the front surface of the steering 43.
　そして、ナビゲーション機能を搭載した高性能の携帯端末装置であるスマホ２００をナビゲーション装置として利用するユーザ（ドライバー）は、通常、左ハンドルの場合には、図３（ａ）にも示すように当該スマホ２００を左側ステアリング４３の近辺（左側、または、右側：一方を破線で示す）に、他方、右ハンドルの場合には、図３（ｂ）にも示すように、当該スマホ２００を右側ステアリング４３の近辺（右側、または、左側：一方を破線で示す）に配置した状態で運転を行う。なお、ここでは図示しないが、具体例として、スマホ２００を収容するためのスタンド等などの固定手段を設けることが好ましいであろう。 A user (driver) who uses a smartphone 200, which is a high-performance portable terminal device equipped with a navigation function, as a navigation device normally has the smartphone as shown in FIG. 200 in the vicinity of the left steering 43 (left side or right side: one is indicated by a broken line), and on the other hand, in the case of the right steering wheel, as shown in FIG. The operation is performed in the vicinity (right side or left side: one is indicated by a broken line). Although not shown here, as a specific example, it may be preferable to provide fixing means such as a stand for housing the smartphone 200.
　本発明では、図に矢印でも示すように、ＨＵＤ装置は、スマホ２００の表示画面２１０上に表示されるナビゲーション情報を、各種の情報をドライバーの前方に虚像として表示させるＨＵＤの画像表示領域（エリア）の一部を利用して表示させるものである。より具体的には、ＨＵＤ装置は、左ハンドルの場合には、スマホ２００の表示画面２１０上に表示されるナビゲーション情報の虚像をＨＵＤの画像表示領域（エリア）の左側に寄せて表示し、他方、右ハンドルの場合には、スマホ２００の表示画面２１０上に表示されるナビゲーション情報の虚像をＨＵＤの画像表示領域（エリア）の右側に寄せて表示する。 In the present invention, as indicated by arrows in the figure, the HUD device displays the navigation information displayed on the display screen 210 of the smartphone 200 as an HUD image display area (area) for displaying various information as virtual images in front of the driver. ) Is used for display. More specifically, in the case of the left handle, the HUD device displays a virtual image of navigation information displayed on the display screen 210 of the smartphone 200 near the left side of the image display area (area) of the HUD, In the case of the right handle, the virtual image of the navigation information displayed on the display screen 210 of the smartphone 200 is displayed near the right side of the image display area (area) of the HUD.
　このことによれば、ドライバーは、運転の際に必要なナビゲーション情報を、スマホ２００の画面２１０上ではなく、比較的に大きな表示領域を有するＨＵＤの画像表示領域（エリア）上において確認することができる。すなわち、意識を路上からスマホの表示画面に集中してしまう「ながらスマホ（携帯）」を解消すると共に、路上からナビゲーション情報への視点移動を小さくスムーズなものとすることが可能となる。 According to this, the driver can confirm the navigation information necessary for driving not on the screen 210 of the smartphone 200 but on the image display area (area) of the HUD having a relatively large display area. it can. That is, it is possible to eliminate “smartphone (mobile)” that concentrates the consciousness on the display screen of the smartphone from the road, and to make the viewpoint movement from the road to the navigation information small and smooth.
　さらに、上述したように携帯端末の設置をステアリングの左右位置に対して配置することで、例えば左ハンドルでは左側を走行する対向車に対する視界を邪魔することがなく、右側からの歩行者の飛出しについても視界を遮ることがない。同様に、右ハンドルでは右側を走行する対向車に対する視界を邪魔することがなく、左側からの歩行者の飛出しについても視界を遮ることがない。 Furthermore, as described above, by placing the mobile terminal with respect to the left and right positions of the steering wheel, for example, the left handle does not disturb the view of the oncoming vehicle traveling on the left side, and the pedestrian jumps from the right side. There is no obstruction in view. Similarly, the right handle does not obstruct the field of view of the oncoming vehicle traveling on the right side, and does not obstruct the field of view of pedestrians flying from the left side.
　また、ドライバーは、運転の際に必要なナビゲーション情報を、表示領域の比較的狭小なスマホ２００上に比較して大きなＨＵＤの画像表示領域（エリア）上において確認することから、スマホ２００の画面へ意識を集中させることなく、必要な情報を容易に把握することができることとなり、ドライバーの負担を大幅に軽減することが可能となる。すなわち、スマホ２００のナビゲーション情報を、ＨＵＤの画像表示領域（エリア）を利用して遠景の情報を上部に近景の情報を画面下部に表示することによって、ドライバーが運転中に見ている実景に重ねることも可能となるため、スマホ２００のナビゲーション機能を利用しながらも、より安全な運転を可能とするものである。 In addition, since the driver confirms the navigation information necessary for driving on the image display area (area) of the large HUD compared to the smartphone 200 having a relatively narrow display area, the driver can go to the screen of the smartphone 200. This makes it possible to easily grasp the necessary information without concentrating the consciousness, and the burden on the driver can be greatly reduced. That is, the navigation information of the smartphone 200 is superimposed on the actual scene that the driver sees while driving by displaying the distant view information at the top and the near view information at the bottom of the screen using the image display area (area) of the HUD. This also enables safer driving while using the navigation function of the smartphone 200.
　また、上記図３における符号６０は、ステアリング４３の一部に取り付けられた、例えば、赤外線カメラを含むカメラを示しており、ここではドライバーの視点を検出する手段を構成する。ドライバーの視点移動を検知した結果を用いて映像表示位置を上下または左右および上下左右に移動させることでより視認性を向上することが可能となる。なお、このドライバーの視点検出手段である視点監視カメラ６０は、必ずしも、上述したようにステアリングの一部に取り付けられる必要はなく、運転者の視点を検出が可能であればよく、例えば、ダッシュボードの一部、または、ウィンドシールド６の一部に取り付けられてもよい。 Further, reference numeral 60 in FIG. 3 indicates a camera including, for example, an infrared camera, which is attached to a part of the steering 43, and here constitutes a means for detecting the driver's viewpoint. Visibility can be further improved by moving the video display position up and down or left and right and up and down and left and right using the result of detecting the viewpoint movement of the driver. Note that the viewpoint monitoring camera 60 that is the driver's viewpoint detection means does not necessarily have to be attached to a part of the steering as described above, and may be any device that can detect the driver's viewpoint. Or a part of the windshield 6 may be attached.
　＜情報表示装置（ＨＵＤ装置）＞
　図４は、本発明の一実施の形態である情報表示装置とその周辺機器構成を示すブロックと概略構成図であり、ここでは、その一例として、特に、自動車のフロントガラスに画像を投影するＨＵＤ装置について説明する。 <Information display device (HUD device)>
FIG. 4 is a block diagram and schematic configuration diagram showing the configuration of an information display apparatus according to an embodiment of the present invention and its peripheral devices. Here, as an example thereof, in particular, a HUD that projects an image on a windshield of an automobile. The apparatus will be described.
　このＨＵＤ装置１は、運転者の視線８において自車両の前方に虚像を形成するが、この虚像は予め設定された単数の位置に形成してもよいが、本実施の形態では、虚像を立体的に表示するため、虚像Ｖ１～Ｖ３を複数の位置それぞれに形成する。そのため、被投影部材６（本実施の形態ではフロントガラス）にて反射された各種情報を虚像ＶＩ（Ｖｉｒｔｕａｌ　Ｉｍａｇｅ）として表示する装置（いわゆる３Ｄ表示のＨＵＤである。なお、被投影部材６は、情報が投影される部材であればよく、前述したフロントガラスだけではなく、その他、コンバイナであってもよい。すなわち、本実施の形態の情報装置１では、運転者の視線８において自車両の前方における複数の位置それぞれに虚像を形成して運転者に視認させるものであり、虚像として表示する情報としては、例えば、車両前方の歩行者や先行する車両の存在を警告するアラート表示（情報）であり、さらには、車両情報や監視カメラやアラウンドビュアーなどのカメラ（図示せず）で撮影した前景情報を含んでもよい。 The HUD device 1 forms a virtual image in front of the host vehicle at the driver's line of sight 8, but this virtual image may be formed at a preset single position, but in the present embodiment, the virtual image is three-dimensional. For virtual display, virtual images V1 to V3 are formed at a plurality of positions, respectively. Therefore, it is a device (so-called 3D display HUD) that displays various information reflected by the projection member 6 (the windshield in the present embodiment) as a virtual image VI (virtual image). Any information projection member may be used, and not only the windshield described above, but also a combiner, that is, in the information device 1 of the present embodiment, the driver's line of sight 8 is ahead of the host vehicle. For example, an alert display (information) that warns the presence of a pedestrian in front of the vehicle or the presence of a preceding vehicle is formed as a virtual image to be visually recognized by the driver by forming a virtual image at each of a plurality of positions in the vehicle. In addition, vehicle information and foreground information captured by a camera (not shown) such as a surveillance camera or an around viewer may be included.
　また、ＨＵＤ装置１は、情報を表示する映像光を投射する映像投写装置１１と、当該映像投写装置１１からの光を結像させる中間像結像部４と、当該中間像結像部４において結像した映像情報（映像光）を収束または発散させる光学部品５と、そして、上記映像投写装置１１を制御する制御装置３０とを備えている。なお、上記の光学部品５は、以下に述べる虚像光学系であり、光を反射させる凹面形状のミラーを含んでいる。また、この光学部品５において反射した光は、被投影部材６にて反射されて運転者の視線８（ＥｙｅＢｏｘ）へと向かう。 The HUD device 1 includes an image projection device 11 that projects image light for displaying information, an intermediate image formation unit 4 that forms an image of light from the image projection device 11, and the intermediate image formation unit 4. An optical component 5 that converges or diverges the image information (image light) that has been formed, and a control device 30 that controls the image projection device 11 are provided. The optical component 5 is a virtual image optical system described below, and includes a concave mirror that reflects light. Further, the light reflected by the optical component 5 is reflected by the projection member 6 and travels toward the driver's line of sight 8 (EyeBox).
　上記の中間像結像部（または、中間像表示部）４は、映像投写装置１１からの光を結像する機能を有しており、例えば、マイクロレンズを２次元状に配置したマイクロレンズアレイにより構成される。本実施の形態においては、中間像結像部４と、接眼光学系を形成する上記凹面反射ミラーから成る光学部品５との間には、光学素子２１および光学素子２２が配置されている。これら光学素子２１および光学素子２２の配置は、第一の目的として、虚像の形成位置を自車両の前方の複数個所（図４においては３箇所）とするためである。さらに第二の目的として、中間像結像部４と接眼光学系を形成する光学部品５との間において、当該中間像結像部４からの映像光が分離する位置において、それぞれ、収差補正を行うためである。なお、これらの光学素子による収差補正によれば、虚像が異なる位置に形成されても、同一の虚像光学系を用いることにより、複数の虚像を異なる倍率で表示することが可能となる。 The intermediate image forming unit (or intermediate image display unit) 4 has a function of forming an image of light from the image projection device 11. For example, a microlens array in which microlenses are two-dimensionally arranged. Consists of. In the present embodiment, an optical element 21 and an optical element 22 are disposed between the intermediate image forming unit 4 and the optical component 5 including the concave reflecting mirror forming the eyepiece optical system. The arrangement of the optical elements 21 and 22 is for the purpose of setting the virtual image forming positions at a plurality of locations in front of the host vehicle (three locations in FIG. 4). Further, as a second object, aberration correction is performed between the intermediate image forming unit 4 and the optical component 5 forming the eyepiece optical system at a position where the image light from the intermediate image forming unit 4 is separated. To do. According to the aberration correction by these optical elements, even if virtual images are formed at different positions, a plurality of virtual images can be displayed at different magnifications by using the same virtual image optical system.
　より具体的には、最も近傍に位置する虚像Ｖ１を形成する光束の収差改善は、光学素子２１により行い、同時に、中間に位置する虚像Ｖ２の収差補正は、光学素子２２により行う。また、最も遠方に形成される虚像Ｖ３は、本来の虚像光学系で収差が最適設計されているため、ここでは光学素子を設けていないが、さらに収差補正能力を向上させるたに最適設計された光学素子を設けても、本発明の技術的思想または範囲を逸脱するものではないことは言うまでもない。なお、ここでは、一例として、虚像Ｖ１は車両前方の１４ｍまたはそれ以上の距離に、虚像Ｖ２は５２ｍまたはそれ以上の距離に、そして、虚像Ｖ３は９３ｍまたはそれ以上の距離に表示する。 More specifically, the optical element 21 corrects the aberration of the light beam forming the nearest virtual image V1 and the optical element 22 corrects the aberration of the intermediate virtual image V2. In addition, since the virtual image V3 formed at the farthest is optimally designed for aberration in the original virtual image optical system, no optical element is provided here, but it was optimally designed to further improve the aberration correction capability. It goes without saying that the provision of an optical element does not depart from the technical idea or scope of the present invention. Here, as an example, the virtual image V1 is displayed at a distance of 14 m or more in front of the vehicle, the virtual image V2 is displayed at a distance of 52 m or more, and the virtual image V3 is displayed at a distance of 93 m or more.
　また、本実施の形態では、説明の都合上、虚像の発生位置を遠方虚像Ｖ３、中間虚像Ｖ２、近接虚像Ｖ１に分割し、それぞれ、個別に光学素子２１および光学素子２２を設けた例について説明したが、これに限定されることはない。例えば、虚像の表示位置を遠方から近接位置まで、連続的に変化させるためには、空間的な光学距離を変化させ、より具体的には光学素子の画面垂直方向の厚さを変化させることで連続的に虚像が発生する位置を変化させ光学素子の両面のレンズ形状を偏心非球面形状または自由曲面形状とすることで十分な収差補正能力を持たせる。この結果、光学素子を１枚として対応しても、やはり、本発明の技術的思想または範囲を逸脱するものではないことは言うまでもない。 In this embodiment, for convenience of explanation, an example in which a virtual image generation position is divided into a far virtual image V3, an intermediate virtual image V2, and a near virtual image V1, and the optical element 21 and the optical element 22 are provided individually, respectively. However, it is not limited to this. For example, in order to continuously change the display position of the virtual image from a distant place to a close position, the spatial optical distance is changed, more specifically, the thickness of the optical element in the vertical direction of the screen is changed. Sufficient aberration correction capability is provided by changing the position where the virtual image is continuously generated to change the lens shape on both surfaces of the optical element to a decentered aspherical shape or a free-form surface shape. As a result, it goes without saying that even if one optical element is used, it does not depart from the technical idea or scope of the present invention.
　以上の説明においては映像表示素子として、中間像結像（または、中間像表示）部４を用いる方式について説明したが、映像表示素子としてＬＣＤ（Ｌｉｑｕｉｄ　Ｃｒｙｓｔａｌ　Ｄｉｓｐｌａｙ）を用いても本発明の技術的思想または範囲を逸脱するものではないことは言うまでもない。 In the above description, the method of using the intermediate image formation (or intermediate image display) unit 4 as the image display element has been described. However, even if an LCD (Liquid Crystal Display) is used as the image display element, the technical aspects of the present invention can be used. It goes without saying that it does not depart from the spirit or scope.
　一方、制御装置３０は、記憶装置３１と、マイクロコンピュータ（以下「マイコン」と記す）３２とを備えている。記憶装置３１は、記憶内容を書き換え可能な不揮発性の記憶装置からなる。マイコン３２は、電源が切断されても記憶内容を保持する必要がある処理プログラムやデータを格納するＲＯＭ３４と、処理プログラムやデータを一時的に収納するＲＡＭ３３と、上記ＲＯＭ３４やＲＡＭ３３に記憶された処理プログラムに従って各種処理を実行するＣＰＵ３５とを有したコンピュータとを中心にして構成されている。 On the other hand, the control device 30 includes a storage device 31 and a microcomputer (hereinafter referred to as “microcomputer”) 32.

It is mainly configured by a computer having a CPU 35 that executes various processes according to a program.
　このうち、ＲＯＭ３４には、車両情報や前景情報などの各種情報が被投影部材６に投影されるように映像投写装置１１を制御する情報表示処理をマイコン３２が実行するための処理プログラムが格納されている。そして、制御装置３０には、車両情報や前景情報の取得元として、少なくとも、ナビゲーション機能を備えた高性能の携帯端末装置であるスマホ２００と共に、運転支援電子制御装置（以下、「運転支援ＥＣＵ（Ｅｌｅｃｔｒｏｎｉｃ　Ｃｏｎｔｒｏｌ　Ｕｎｉｔ）と記載）４２と、さらには、上述した視点監視カメラ６０が、有線や無線により互いに接続されている。 Among these, the ROM 34 stores a processing program for the microcomputer 32 to execute information display processing for controlling the image projection device 11 so that various information such as vehicle information and foreground information is projected onto the projection target member 6. ing. The control device 30 includes, as a source of vehicle information and foreground information, at least a smartphone 200 that is a high-performance portable terminal device having a navigation function, and a driving support electronic control device (hereinafter referred to as “driving support ECU”). (Electronic Control Unit) 42) and the above-described viewpoint monitoring camera 60 are connected to each other by wire or wirelessly.
　なお、ここでナビゲーションシステムを構成するスマホ２００は、内蔵した位置検出装置にて検出した現在位置を基に、地図データ記憶部に記憶されている地図データに照合した結果に従って、設定された目的地までの経路を案内する装置である。なお、この地図データには、道路の制限速度や車線数、交差点に関する情報などの各種の情報（いわゆる、地図やルート情報を含むナビゲーション情報）が含まれている。 Here, the smartphone 200 constituting the navigation system has a destination set according to the result of collation with the map data stored in the map data storage unit based on the current position detected by the built-in position detection device. It is a device to guide the route to. The map data includes various types of information (so-called navigation information including maps and route information) such as information on road speed limits, the number of lanes, and intersections.
　制御装置３０は、このようなスマホ２００から、自車両が走行している現在位置に対応する道路の制限速度や車線数、ナビゲーションシステムに設定された自車両の移動予定経路などの情報を前景情報（すなわち、上記虚像により自車両の前方に表示する情報）として取得する。 The control device 30 provides foreground information such as the speed limit of the road corresponding to the current position where the host vehicle is traveling, the number of lanes, the planned travel route of the host vehicle set in the navigation system, and the like from the smartphone 200. (That is, information displayed in front of the host vehicle by the virtual image).
　運転支援ＥＣＵ６２は、周辺監視装置６３での監視の結果として検出された障害物に従って駆動系や制御系を制御することで、運転支援制御を実現する制御装置であり、運転支援制御としはクルーズコントロール、アダプティブクルーズコントロール、プリクラッシュセーフティ、レーンキーピングアシストなどの周知技術を含む。 The driving support ECU 62 is a control device that realizes driving support control by controlling the drive system and the control system in accordance with the obstacle detected as a result of monitoring by the periphery monitoring device 63, and cruise control is used as the driving support control. , Including well-known technologies such as adaptive cruise control, pre-crash safety, lane keeping assistance.
　周辺監視装置６３は、自車両の周辺の状況を監視する装置であり、一例としては、自車両の周辺を撮影した画像に基づいて自車両の周辺に存在する物体を検出するカメラや、探査波を送受信した結果に基づいて自車両の周辺に存在する物体を検出する探査装置などである。また、周辺監視装置６３は、上述したカメラにより外光を検知（センシング）して昼または夜の区別を行ってもよい。 The periphery monitoring device 63 is a device that monitors the situation around the host vehicle.

An exploration device that detects an object that exists in the vicinity of the host vehicle based on the result of transmitting and receiving the vehicle. Further, the periphery monitoring device 63 may detect daylight or nighttime by detecting (sensing) external light with the above-described camera.
　制御装置３０は、このような運転支援ＥＣＵ６２からの情報（例えば、先行車両までの距離および先行車両の方位、障害物や標識が存在する位置など）を前景情報として取得する。さらに、制御装置３０には、イグニッション（ＩＧ）信号、および、自車状態情報が入力される。これらの情報の内、自車状態情報とは、車両情報として取得される情報であり、例えば、内燃機関の燃料の残量や冷却水の温度など予め規定された異常状態となったことを表す警告情報を含んでいる。また、方向指示器の操作結果や自車両の走行速度、シフトポジションなどの情報も含まれている。以上述べた制御装置３０はイグニッション信号が入力されると起動する。以上が本発明の一実施の形態である情報表示装置の全体システムの説明である。 The control device 30 acquires such information from the driving support ECU 62 (for example, the distance to the preceding vehicle, the heading direction of the preceding vehicle, the position where the obstacle or sign is present, etc.) as the foreground information. Furthermore, an ignition (IG) signal and own vehicle state information are input to the control device 30. Among these pieces of information, the own vehicle state information is information acquired as vehicle information, and represents, for example, that a predetermined abnormal state such as the remaining amount of fuel in the internal combustion engine or the temperature of the cooling water has been entered. Contains warning information. Information such as the operation result of the direction indicator, the traveling speed of the host vehicle, and the shift position is also included. The control device 30 described above is activated when an ignition signal is input. The above is the description of the entire system of the information display apparatus according to the embodiment of the present invention.
　上述したように、本発明の情報表示装置では、ユーザ（ドライバー）が携帯して使用するナビゲーション機能を搭載したスマホ２００を、ナビゲーション情報の情報源として利用する。かかる形態によれば、ユーザは、自己のスマホ２００のナビゲーション情報の設定（例えば、目的地や走行ルートの設定等）を、自車両に搭乗している以外の時間や場所においても行うことができるため、その利便性がさらに向上する。また、スマホ２００からのナビゲーション情報の伝送方法として上述したBluetoothやＷｉｆｉ等の無線ＬＡＮを利用することによれば、スマホ２００を車内の所定の位置に配置するだけでよく、利用者の利便性に優れたものとなる。他方、有線の接続端子を利用して伝送することも可能であり、その場合には、接続端子をスマホ２００の充電端子と共用可能とすることによれば、ナビゲーション情報使用と同時に、スマホ２００の充電が可能となるという利便性が可能となろう。 As described above, in the information display device of the present invention, the smartphone 200 equipped with a navigation function carried and used by the user (driver) is used as an information source of navigation information. According to this mode, the user can set the navigation information of his / her smartphone 200 (for example, setting of a destination and a travel route) at a time and place other than when he / she is on the vehicle. Therefore, the convenience is further improved. Also, by using the above-described wireless LAN such as Bluetooth or WiFi as a method of transmitting navigation information from the smartphone 200, it is only necessary to place the smartphone 200 at a predetermined position in the vehicle, which is convenient for the user. It will be excellent. On the other hand, it is also possible to transmit using a wired connection terminal. In this case, by using the connection terminal in common with the charging terminal of the smartphone 200, the navigation information can be used simultaneously with the use of the navigation information. The convenience of being able to charge will be possible.
　＜ナビゲーション情報の表示形態＞
　続いて、上述した情報表示装置により生成された虚像のＨＵＤ画像表示領域における表示の形態について、以下に詳細に説明する。 <Display format of navigation information>
Subsequently, a display form of the virtual image generated by the information display device described above in the HUD image display area will be described in detail below.
　本発明の情報表示装置では、基本的には、上述したように、スマホ２００の表示画面２１０上に表示される地図を含むナビゲーション情報を、ＨＵＤ装置１を利用することにより、自車両の前方に虚像として表示する（図３、図４を参照）。その際、ナビゲーション情報の表示方向を自車両の進行方向と一致させて表示することによりドライバーにとってより自然なナビゲーション情報の表示が可能となろう。 In the information display device of the present invention, basically, as described above, navigation information including a map displayed on the display screen 210 of the smartphone 200 is displayed in front of the host vehicle by using the HUD device 1. Displayed as a virtual image (see FIGS. 3 and 4). At that time, it is possible to display navigation information more natural for the driver by displaying the navigation information in the same direction as the traveling direction of the host vehicle.
　また、上記の説明では、スマホ２００上のナビゲーション情報をそのまま（すなわち、１：１の比率で）ＨＵＤの画像表示領域（エリア）上に表示するものとして説明したが、本発明はそれに限定されることなく、その表示領域の全体または一部を、拡大または縮小して表示することも可能である。なお、その際には、挿入補間や間引き等の技術を利用することによって表示する画素を調整することにより、必要なナビゲーション情報を選択し、所望の解像度で表示することが可能であることは当業者であれば自明であろう。 In the above description, the navigation information on the smartphone 200 is described as it is displayed on the image display area (area) of the HUD as it is (that is, at a ratio of 1: 1), but the present invention is limited to this. The entire or part of the display area can be enlarged or reduced without being displayed. In this case, it is possible to select necessary navigation information and display it at a desired resolution by adjusting the display pixels by using techniques such as insertion interpolation and thinning. If it is a trader, it will be obvious.
　加えて、次世代の技術であるビッグデータ（高精度３Ｄ地図情報）やＡＩ情報（予測危険情報等）を利用したナビゲーション情報を考慮した場合には、上述した虚像の表示位置を遠方から近接した位置に変化させることにより、立体感のあるよりリアルなナビゲーション情報の表示が可能となる。その一例として、図５（ａ）には、近距離のナビゲーション情報に予測危険情報（周辺監視装置６３での監視の結果として検出された歩行者や先行する車両等をアラート表示する）を加えて表示した例を、また、図５（ｂ）には、高精度３Ｄ地図情報を表示した例を示している。 In addition, when navigation information using big data (high-precision 3D map information) or AI information (predictive danger information, etc.), which is the next generation technology, is taken into account, the display position of the virtual image described above is approached from a distance. By changing the position, more realistic navigation information with a stereoscopic effect can be displayed. As an example, in FIG. 5A, predictive danger information (alert display of a pedestrian or a preceding vehicle detected as a result of monitoring by the peripheral monitoring device 63) is added to the short-distance navigation information. An example of display is shown, and FIG. 5B shows an example of displaying high-precision 3D map information.
　このように、スマホ２００上のナビゲーション情報をＨＵＤの画像表示領域（エリア）を利用して表示することによれば、特に、高さ情報や奥行情報を含んだ３次元高精度地図情報を含むナビゲーション情報を、スマホ２００の表示画面２１０に比較してより大きく、かつ、３Ｄ表示機能を含んだＨＵＤの表示領域に表示することができることから、よりリアルな３次元地図情報の表示が可能となる。 Thus, by displaying the navigation information on the smartphone 200 using the image display area (area) of the HUD, in particular, navigation including 3D high-precision map information including height information and depth information. Since the information is larger than the display screen 210 of the smartphone 200 and can be displayed in the display area of the HUD including the 3D display function, more realistic 3D map information can be displayed.
　＜情報表示装置の容積等＞
　続いて、上述した情報表示装置の容積と大型化するＨＵＤの画像表示領域（エリア）との関係について図６を参照して説明する。すなわち、情報表示装置の容積は、ＨＵＤ画像表示領域（エリア）の視野角（横（Ｈ）、縦（Ｖ））の増大に伴って増加している。具体的には、（視野角［１０×７］、虚像距離（２０ｍ）では、凹面ミラーを含む光学系の大型化によってＨＵＤのセット容積が１８Ｌを越えてしまい、当該装置の搭載場所であるフロントガラスとステアリングとの間の空間内に収納することができないという問題が指摘される。そこで、以下では、ＨＵＤ画像表示領域（エリア）の視野角の増大に伴う装置容量の増大を解決するための情報表示装置の構造についても述べる。 <Volume of information display device, etc.>
Next, the relationship between the volume of the information display device described above and the image display area (area) of the HUD that is enlarged will be described with reference to FIG. That is, the volume of the information display device increases as the viewing angle (horizontal (H), vertical (V)) of the HUD image display area (area) increases. Specifically, at (viewing angle [10 × 7] and virtual image distance (20 m), the set volume of the HUD exceeds 18 L due to the enlargement of the optical system including the concave mirror, and the front where the apparatus is mounted In view of the above, it is pointed out that the problem cannot be accommodated in the space between the glass and the steering wheel. The structure of the information display device is also described.
　図７および図８には、小型化に適した情報表示装置であるＨＵＤ装置１の構成と配置（レイアウト）が示されている。これらの図において、下流側から順に、フロントガラス６を介して虚像を形成する映像光を投射する凹面（自由曲面）ミラー５ａ、その際に発生する歪や収差を補正するための補正用のレンズ群２、映像表示装置１１、バックライトを構成する発光ダイオードを光源としたバックライト光源１０が設けられている。 7 and 8 show the configuration and arrangement (layout) of the HUD device 1 which is an information display device suitable for downsizing. In these drawings, in order from the downstream side, a concave (free curved surface) mirror 5a for projecting image light that forms a virtual image through a windshield 6, and a correction lens for correcting distortion and aberration generated at that time. The group 2, the image display device 11, and the backlight light source 10 using light emitting diodes constituting the backlight as a light source are provided.
　また、符号７は筐体である。さらに、ＨＵＤ装置１の内部に侵入する太陽光のＰ波成分を抑制するため、その一例として、レンズ群２と映像表示装置１１の間には、Ｐ波成分を抑制するための光学手段３が設けられている。そして、筐体７の上面には、映像光が自動車のフロントガラスに向かって投射される開口部が形成されており、当該開口部は防眩板（グレアトラップ）４１によって覆われている。また、ここでは図示しないが、上記凹面ミラー５ａの位置を調整するための電動モータ等により構成される凹面ミラー駆動部が凹面ミラー５ａと一体に設けられている。そして、ＬＣＤと凹面ミラーとの間の距離を最小限に確保しながら、これら構成部品はモジュール化されてコンパクトに形成されている。 Moreover, the code | symbol 7 is a housing | casing. Furthermore, in order to suppress the P wave component of sunlight entering the inside of the HUD device 1, as an example, an optical means 3 for suppressing the P wave component is provided between the lens group 2 and the image display device 11. Is provided. An opening for projecting image light toward the windshield of the automobile is formed on the upper surface of the housing 7, and the opening is covered with an antiglare plate (glare trap) 41. Further, although not shown here, a concave mirror driving unit constituted by an electric motor or the like for adjusting the position of the concave mirror 5a is provided integrally with the concave mirror 5a. These components are modularized and compactly formed while ensuring a minimum distance between the LCD and the concave mirror.
　かかる構成・配置において、視野角を拡大するためには、例えば、凹面ミラー５ａを回転駆動することにより、また、虚像距離の遠方化を実現するためには、光学手段３を適切に設定することなどによって所望の特性を実現することができる。または、レーザ光をＭＥＭＳ素子でフロントガラスにスキャンして実像を得る第２の情報表示装置を加えてＨＵＤ画像表示領域（エリア）を拡大することも可能であろう。 In such a configuration / arrangement, in order to enlarge the viewing angle, for example, the concave mirror 5a is rotationally driven, and in order to realize a farther virtual image distance, the optical means 3 is appropriately set. The desired characteristics can be realized by such as. Alternatively, the HUD image display area (area) may be enlarged by adding a second information display device that scans laser light onto the windshield with a MEMS element to obtain a real image.
　すなわち、上述した構成・配置のＨＵＤ装置１００を採用することによれば、上述したＨＵＤ画像表示領域（エリア）の視野角の増大に伴う装置容量の増大を解決して、ＨＵＤ装置をその搭載場所であるフロントガラスとステアリングの間の空間内に収納することが可能となる。 That is, by adopting the HUD device 100 having the configuration and arrangement described above, the increase in the device capacity accompanying the increase in the viewing angle of the HUD image display area (area) described above can be solved, and the HUD device can be mounted on the HUD device. It can be housed in the space between the windshield and the steering wheel.
