Abstract

There is provided an on-vehicle display having a simple configuration for reducing intrusion and reflection of solar light on the display surface. The on-vehicle display acquires current date and time from a current date acquiring section (1) and acquires current position of a vehicle from a current position acquiring section (2). A control section (7) receives an input to an operating section (3) by an operator and drives an angle adjusting section (8) to alter the angle of a display section (9). An initially set angle of the display section (9) set after a drivers sits in a vehicle is altered to an angle setting of alteration time for avoiding glare through operation of the operating section (3) by the operator. After this, when an alteration time obtained with reference to an angle control table (4) is reached, the control section (7) automatically returns the set angle of the display section (9) from the angle setting of alteration time to the initially set angle.

[0005] 本発明の車載用表示装置は、映像を表示する表示部と、前記表示部の設置角度 を調整する角度調整部と、前記表示部の設置角度を設定するため前記角度調整部 を制御する制御部と、操作者が、前記表示部の設置角度を第 1の設定角度及び該 第 1の設定角度と所定角度量異なる第 2の設定角度に設定する操作を入力する操作 部と、を備え、前記制御部は、操作者が前記操作部より前記表示部の設置角度を前 記第 2の設定角度に設定する操作を入力した後所定条件の成立時に、前記表示部 の設置角度を前記第 2の設定角度から第 1の設定角度に変更するよう前記角度調整 部を制御する。 [0005] The in-vehicle display device of the present invention includes a display unit that displays an image, an angle adjustment unit that adjusts an installation angle of the display unit, and the angle adjustment unit that sets an installation angle of the display unit. A control unit for controlling the operation unit, and an operation unit for an operator to input an operation for setting the installation angle of the display unit to a first set angle and a second set angle different from the first set angle by a predetermined angle amount; The control unit includes an installation angle of the display unit when a predetermined condition is satisfied after an operator inputs an operation for setting the installation angle of the display unit to the second set angle from the operation unit. The angle adjustment unit is controlled so as to change the second setting angle from the second setting angle to the first setting angle.
[0006] 上述の構成では、操作者が、眩しさを避けるため等の理由で表示部を第 2の設定 角度に設定した後、予め定められた所定条件が成立すると、表示部の設置角度が第 1の設定角度に自動的に変更される。したがって、簡易な機構で良好な視認状態が 、ほとんどの場合において得られることとなる。  [0006] In the above-described configuration, when the predetermined setting condition is satisfied after the operator sets the display unit to the second setting angle for reasons such as to avoid glare, the installation angle of the display unit is changed. It is automatically changed to the first setting angle. Accordingly, a good visual recognition state can be obtained with a simple mechanism in most cases.
[0007] 前記制御部は、前記所定条件の成立後、当該所定条件が不成立となった時、前記 表示部の設置角度を前記第 1の設定角度から前記第 2の設定角度に変更してもよ 、  [0007] After the predetermined condition is satisfied, the control unit may change the installation angle of the display unit from the first set angle to the second set angle when the predetermined condition is not satisfied. Yo
[0008] また、前記所定条件の成立時は、所定の時間帯又は太陽の仰角が所定の範囲外 にある時間帯である。これにより簡易に所定条件を決めることができる。 [0008] Further, when the predetermined condition is satisfied, it is a predetermined time zone or a time zone in which the elevation angle of the sun is outside the predetermined range. Thereby, the predetermined condition can be easily determined.
[0009] さらに、表示装置には、現在の月日及び時刻を取得する現在日時取得部と、現在 の車両の位置を取得する現在位置取得部と、月日を含む所定の期間と車両の位置 を対応させたマトリックス中に、前記所定条件の成立を示すとともに前記表示部の設 置角度を変更する変更時刻を記述した角度制御テーブルを記憶する記憶部とを設 けることができる。この場合、前記制御部は、前記現在日時取得部から取得した現在 の月日及び時刻並びに前記現在位置取得部から取得した現在の車両の位置と、前 記角度制御テーブル中の前記変更時刻を比較して、前記角度量により前記表示部 の設置角度を変更するか否力判断する。  [0009] Further, the display device includes a current date acquisition unit for acquiring the current date and time, a current position acquisition unit for acquiring the current vehicle position, a predetermined period including the month and day, and the vehicle position. And a storage unit for storing an angle control table that describes a change time for changing the installation angle of the display unit and indicating the establishment of the predetermined condition. In this case, the control unit compares the current date and time acquired from the current date and time acquisition unit, the current vehicle position acquired from the current position acquisition unit, and the change time in the angle control table. Then, it is determined whether or not to change the installation angle of the display unit according to the angle amount.
[0010] 上述のテーブルは計算により予め求めることができる。このようなテーブルを予め用 意しておくことにより、複雑な計算を行なう必要がなくなり、装置の構成を簡易なものと することができる。  [0010] The above table can be obtained in advance by calculation. By preparing such a table in advance, it is not necessary to perform complicated calculations, and the configuration of the apparatus can be simplified.
[0011] 前記角度制御テーブルには、前記対応付けられた期間と位置における太陽の位置 の仰角に基づき決定された前記変更時刻が記述されている。この変更時刻は、午前 の変更時刻と午後の変更時刻を含むことができる。また、前記記憶部は、装置が搭 載される車両の種類に対応した複数の角度制御テーブルを記憶してもよい。 [0011] The angle control table describes the change time determined based on the elevation angle of the sun position in the associated period and position. This change time is Change time and afternoon change time. The storage unit may store a plurality of angle control tables corresponding to the type of vehicle on which the apparatus is mounted.
[0012] 前記第 1の設定角度は、一般的には車載用表示装置の駆動後、操作者によって最 初に設定された初期設定角度である。また、前記第 2の設定角度は、前記初期設定 角度の設定の後、操作者によって設定された変更時設定角度である。また、前記角 度調整部は前記表示部の垂直方向の設置角度を調整するのが一般的である。 発明の効果  [0012] The first set angle is generally an initial set angle initially set by an operator after driving the in-vehicle display device. The second set angle is a change-time set angle set by the operator after the initial set angle is set. The angle adjusting unit generally adjusts the vertical installation angle of the display unit. The invention's effect
[0013] 以上の説明から明らかなように、本発明の車載用表示装置においては、表示部に 太陽の直射光が入射する時間帯において、表示部の設置角度が自動調整される。 複雑な太陽光方位、高度の計算を必要としないため、装置への負担を軽減でき、比 較的簡単かつ動作が煩雑とならな!/、装置を実現できる。  As is apparent from the above description, in the in-vehicle display device of the present invention, the installation angle of the display unit is automatically adjusted in the time zone in which the direct sunlight is incident on the display unit. Since it does not require complicated calculation of sunlight direction and altitude, the burden on the device can be reduced, and the device can be realized with relatively simple and complicated operation!

The vehicle type information acquisition unit 6 can determine a mounted vehicle type by holding a plurality of pieces of vehicle type information in a code format in advance and determining a correspondence with an externally input code. Based on the determined vehicle type, four angle control tables and a table corresponding to the vehicle type are selected. Of course, if the vehicle type to be installed is determined from the beginning, the vehicle type information acquisition unit is unnecessary, and the angle control table 4 is included in the vehicle type. There is no need to have multiple tables according to your needs! /.
[0023] 制御部 7は、プロセッサによって実行される各種プログラムを記憶するメモリ、プログ ラム実行時のワークエリアとなるメモリおよび車載用表示装置の各種設定データを記 憶するメモリ等の各種メモリ（図示せず)を含んでいる。これらのメモリは、その用途に 応じて、アクセス速度、記憶容量または揮発性と不揮発性の別等の異なる複数種類 のメモリが用いられる。制御部 7は、現在時刻が角度制御テーブルに格納された上述 した変更時刻 (又は時間帯)と一致すると、表示部を所定の設定角度に設置するよう 制御する。  [0023] The control unit 7 is a memory for storing various programs executed by the processor, a memory serving as a work area during program execution, and various memories such as a memory for storing various setting data of the in-vehicle display device (see FIG. (Not shown). For these memories, different types of memory such as access speed, storage capacity, volatile and non-volatile, etc. are used depending on the application. When the current time coincides with the above-described change time (or time zone) stored in the angle control table, the control unit 7 controls the display unit to be installed at a predetermined set angle.
[0024] 角度調整部 8は、表示部 9の設置角度を電気的または機械的に調整する。調整方 向は、垂直方向のみまたは水平方向のみでもよぐ垂直方向および水平方向両方に 角度調整できる機構を備えていてもよい。角度調整部 8の構成は特に限定はされな い。  The angle adjusting unit 8 adjusts the installation angle of the display unit 9 electrically or mechanically. The adjustment direction may be provided with a mechanism capable of adjusting the angle in both the vertical direction and the horizontal direction, which may be only the vertical direction or only the horizontal direction. The configuration of the angle adjustment unit 8 is not particularly limited.
[0025] 表示部 9は、ナビゲーシヨン時の地図情報、操作メニュー及び入力データ等の表示 や、 DVD等の映像記録媒体に記録された映像を表示するもので、一般的には液晶 ディスプレイによって構成されるが、その構成は特に限定はされない。  [0025] The display unit 9 displays map information, operation menus, input data, and the like during navigation, and displays images recorded on a video recording medium such as a DVD, and is generally configured by a liquid crystal display. However, the configuration is not particularly limited.
[0026] 図 2は、本発明の車載用表示装置における操作の概念を示した概念図である。一 般的に車両への乗車時に、運転者または同乗者等の表示装置の操作者が、自ら視 認しゃすい角度に表示部 9の設置角度を調整する (乗車時 TILT設定、第 1の設定 角度)。しかしながら時間の経過に伴う太陽の上昇 (午前中）又は太陽の下降 (午後 中）とともに、太陽の直射光が表示部 9に入射しやすくなるとともに、操作者が眩しい と感じやすくなる。「直射光」とは、その表示部 9からの反射光が操作者の目の方向に 反射し、直接目に入る方位の太陽光である。  FIG. 2 is a conceptual diagram showing the concept of operation in the in-vehicle display device of the present invention. In general, when riding a vehicle, the operator of the display device, such as a driver or passenger, adjusts the installation angle of the display unit 9 to the viewing angle (the TILT setting when riding, the first setting). angle). However, as the sun rises (morning) or descends (afternoon) over time, direct sunlight is more likely to enter the display unit 9 and the operator is more likely to feel dazzling. The “direct light” is sunlight in the direction in which the reflected light from the display unit 9 is reflected in the direction of the eyes of the operator and directly enters the eyes.
[0027] そこで、本装置にぉ ヽては、操作者が操作部 3を構成する「直射回避ボタン」を押 すと、このような状況下の時間帯、すなわち直射光が表示部 9に入射する時間帯に おいて、さらに表示部 9が垂直方向（図では上向き方向）に所定の角度量の分だけ 傾けられ、直射光の入射を回避するとともに、視認性を確保することが可能となる（2 段階 TILT、第 2の設定角度)。この状態は、直射光が表示部 9に入射する時間帯に おいて維持され、直射光が表示部 9に入射する時間帯を過ぎた後、すなわち直射光 が操作者に届かな 、と 、う所定条件の成立時に、表示部 9の傾きは再び元の状態（ 乗車時の状態、第 1の設定角度）に戻る。直射光が表示部 9に入らない状況になって も 2段階 TILTを維持させておくのは、操作者にとって好ましくないからである。 [0027] Therefore, when the operator presses the "direct-light avoidance button" constituting the operation unit 3, the time zone under such a situation, that is, direct light is incident on the display unit 9. Further, the display unit 9 is tilted by a predetermined angle amount in the vertical direction (upward direction in the figure) during the time period during which it is possible to avoid incidence of direct light and ensure visibility. (Two-stage TILT, second set angle). This state is maintained in the time zone in which the direct light is incident on the display unit 9, and after the time period in which the direct light is incident on the display unit 9, that is, the direct light. If the predetermined condition is satisfied, the inclination of the display unit 9 returns to the original state (the state when boarding, the first set angle). This is because it is not preferable for the operator to maintain the two-stage TILT even when direct light does not enter the display unit 9.
[0028] 図 3は、上述した直射光が表示部 9に入射する時間帯に対応する太陽の位置を示 す図である。図 3で示された角度 θ 1及び Θ 2は、太陽の位置に対応する角度 (仰角 )であり、太陽の仰角が θ 1から Θ 2の仰角範囲内にある場合、直射光が表示部 9に 入射して操作者の目の方向に反射する。逆にいえば、太陽の仰角が θ 1から Θ 2の 仰角範囲外にある場合は、直射光は操作者の目の方向に反射せず、上述した所定 条件が成立する。ここで、 θ 1および Θ 2は、車両全体や窓部等の寸法により異なる 力 予め車種ごとに計算により求めることができる。例えばある車両では実験の結果、 0 1 = 3度、 Θ 2 = 28度と求められた。従って、特定の月日、車両の位置 (緯度、経度 )において、太陽の仰角が θ 1および Θ 2となる時刻も、車種ごとに予め算出すること ができる。従って、直射光は操作者の目の方向に反射しないという上述した所定条 件が成立する時間帯も算出される。本例では θ 1及び Θ 2は、図示した水平面、すな わち地面と平行な面を基準面にして定義されているが、 θ 1及び 0 2の定義の方法 は特に限定されない。 FIG. 3 is a diagram showing the position of the sun corresponding to the time zone in which the direct light described above is incident on the display unit 9. The angles θ 1 and Θ 2 shown in FIG. 3 are angles (elevation angles) corresponding to the position of the sun. When the elevation angle of the sun is within the elevation angle range of θ 1 to Θ 2, direct light is displayed on the display unit 9. Is incident on and reflected in the direction of the operator's eyes. Conversely, when the elevation angle of the sun is outside the elevation angle range of θ 1 to Θ 2, the direct light is not reflected in the direction of the operator's eyes, and the predetermined condition described above is satisfied. Here, θ 1 and Θ 2 can be obtained by calculation for each vehicle type in advance, which varies depending on the size of the entire vehicle, the window, and the like. For example, in some vehicles, as a result of experiments, 0 1 = 3 degrees and Θ 2 = 28 degrees were obtained. Therefore, the time at which the elevation angle of the sun becomes θ 1 and Θ 2 at a specific date and vehicle position (latitude, longitude) can also be calculated in advance for each vehicle type. Accordingly, a time zone in which the above-described predetermined condition that direct light does not reflect in the direction of the eyes of the operator is also calculated. In this example, θ 1 and Θ 2 are defined with the horizontal plane shown, that is, a plane parallel to the ground as a reference plane, but the method of defining θ 1 and 0 2 is not particularly limited.
[0029] 図 4及び図 5は、 Θ 1 = 3度、 Θ 2 = 28度の車両において、上述した計算により求め た、直射光が表示部 9に入射する時間帯に関する情報を記述した角度制御テープ ル 4の例を示す。ただし、操作者の好みの角度 (初期設定角度）に早めに戻るように 制御するため、 Θ 1 =0度、 Θ 2 = 30度に設定した上で、角度制御テーブル 4は作成 されている。この例では、角度制御テーブル 4は、月日力もなる所定の期間と、緯度 及び経度カゝらなる特定範囲の位置情報を対応させたマトリックスカゝら構成される。そし て、マトリックスの各セルには、表示部 9の設置角度を、所定の角度量変更した変更 時設定角度 (第 2の設定角度)から乗車時に操作者自身が設定した初期設定角度（ 第 1の設定角度）に変更するべき時刻が含められている。この時刻は午前の変更時 刻 (朝)と午後の変更時刻（夕方)の二つを含み、角度設定を解除する時刻に相当す る。なお、変更時刻は午前又は午後のみのどちらか一方のみであっても構わない。  [0029] Figs. 4 and 5 show the angle control describing the information about the time zone in which the direct light is incident on the display unit 9 obtained by the above calculation in the vehicle of Θ 1 = 3 degrees and Θ 2 = 28 degrees. An example of Table 4 is shown. However, the angle control table 4 is created after setting Θ 1 = 0 degrees and Θ 2 = 30 degrees in order to perform control so that the angle returns to the operator's preferred angle (initial setting angle) as soon as possible. In this example, the angle control table 4 is configured by a matrix camera in which a predetermined period in which the monthly power is also associated with position information in a specific range such as latitude and longitude. In each cell of the matrix, the installation angle of the display unit 9 is changed from the set angle at the time of change (second set angle) by changing the predetermined angle amount (second set angle) to the initial set angle (first set) set by the operator himself when boarding. Time to be changed is included. This time includes the morning change time (morning) and the afternoon change time (evening), and corresponds to the time to cancel the angle setting. Note that the change time may be either morning or afternoon only.
[0030] 例えば、 1月 30日において、車両が北緯 40度、東経 140度の位置にある場合、最 初に角度設定を解除すべき時刻は午前 10時 45分であり、次に角度設定を解除す べき時間は午後 17時 00分であると記述されている。従って、操作者が乗車時に初期 設定角度に表示部 9を設定し、午前 9時 00分において、眩しさを感じて操作部 3を操 作すると、表示部 9は所定角度量上向き又は下向きに傾くことで変更時設定角度に 設定されるが、午前 10時 45分になると、表示部 9は乗車時の初期設定角度に戻る。 [0030] For example, on January 30, if the vehicle is 40 degrees north latitude and 140 degrees east longitude, It is described that the time to release the angle setting first is 10:45 am, and the time to release the angle setting next is 17:00 pm. Therefore, when the operator sets the display unit 9 to the initial setting angle when getting on and operates the operation unit 3 with dim feeling at 9:00 am, the display unit 9 tilts upward or downward by a predetermined angle amount. However, at 10:45 am, the display unit 9 returns to the initial setting angle when riding.
[0031] また、午前 10時 45分を過ぎた午前 11時 00分でも、操作者が依然として眩しさを感 じて操作部 3を操作すると、表示部 9は所定角度量上向き又は下向きに再び傾き、変 更時設定角度に設定されるが、午後 17時 00分になると、表示部 9は乗車時の初期 設定角度に戻る。 [0031] In addition, even at 11:00 am after 10:45 am, when the operator still feels dazzling and operates the operation unit 3, the display unit 9 tilts again upward or downward by a predetermined angle amount. The setting angle is set at the time of change, but at 17:00 pm, display 9 returns to the initial setting angle when riding.
[0032] 表示部 9が移動する所定の角度量は任意に設定することができる。例えば 10度に 設定することができる。角度量は、時刻や位置に拘わらず固定してもよいし、時刻及 び Z又は位置に応じて変化させてもよい。また、 5度の如き所定の角度量を単位移 動量とし、移動パターンに応じて単位移動量の数を変更させることにより、合計の角 度量を変更させてもよい。  [0032] The predetermined angular amount by which the display unit 9 moves can be arbitrarily set. For example, it can be set to 10 degrees. The angle amount may be fixed regardless of the time and position, or may be changed according to the time and Z or position. Further, the total angular amount may be changed by setting a predetermined angular amount such as 5 degrees as a unit moving amount and changing the number of unit moving amounts according to the moving pattern.
[0033] また、車種ごとに、すなわち、異なる θ 1及び Θ 2の組ごとに、記憶部 5に複数の角 度制御テーブル 4を持たせることができる。この場合、車種情報取得部 6によって検 知された搭載車両に応じて対応するテーブルが選択される。もちろん、最初から搭載 される車種が決まっている場合、車種情報取得部は不要であり、記憶部 5が車種に 応じた複数の角度制御テーブル 4を持つ必要もな 、。  [0033] Further, the storage unit 5 can have a plurality of angle control tables 4 for each vehicle type, that is, for each set of different θ 1 and Θ 2. In this case, the corresponding table is selected according to the mounted vehicle detected by the vehicle type information acquisition unit 6. Of course, when the vehicle type to be installed is determined from the beginning, the vehicle type information acquisition unit is unnecessary, and the storage unit 5 does not need to have a plurality of angle control tables 4 according to the vehicle type.
[0034] 次いで、本実施の形態における車載用表示装置の動作の詳細を、図 6に基づいて 説明する。操作者が、乗車時または走行中に表示部 9の設置角度を好みの初期設 定角度 (第 1の設定角度）に初期設定する。直射光が表示部 9に入射し、操作者が「 直射回避ボタン」を押すと (ステップ S111 ;YES)、表示部 9の設置角度が、初期設 定角度から変更した変更時設定角度 (第 2の設定角度）になるよう、制御部 7が所定 の角度量の分、角度調整部 8を制御し、表示部 9が駆動される (ステップ S112)。  Next, details of the operation of the in-vehicle display device according to the present embodiment will be described with reference to FIG. The operator initially sets the installation angle of the display unit 9 to the desired initial setting angle (first setting angle) while riding or traveling. When direct light is incident on the display unit 9 and the operator presses the `` direct sunlight avoidance button '' (step S111; YES), the setting angle of the display unit 9 is changed from the initial setting angle (second The control unit 7 controls the angle adjustment unit 8 by a predetermined angle amount so that the display unit 9 is driven (step S112).
[0035] さらに、午前中において現在時刻力 角度制御テーブル 4が保持する月日、位置（ 緯度及び経度）に対応した仰角が Θ 2となる変更時刻と一致するか、又は午後にお いて現在時刻が、角度制御テーブル 4が保持する月日、位置 (緯度及び経度）に対 応した仰角が θ 1となる変更時刻と一致すると (ステップ S113 ;YES)、表示部 9の設 置角度力 Sステップ S112で設定された変更時設定角度力も初期設定角度に戻るよう 、所定の角度量の分、制御部 7が角度調整部 8を制御し、表示部 9が駆動される (ス テツプ S 114)。 [0035] Further, in the morning, the current time, the angle control table 4 holds the date and time (latitude and longitude) corresponding to the change time at which the elevation angle corresponding to Θ2 becomes Θ2, or the current time in the afternoon Is the date and position (latitude and longitude) stored in the angle control table 4. When the corresponding elevation angle coincides with the change time at which θ 1 becomes (step S113; YES), the set angular force of the display unit 9 S The set angular force at the time of change set in step S112 is set to a predetermined angle The control unit 7 controls the angle adjusting unit 8 by the amount, and the display unit 9 is driven (step S 114).
[0036] 尚、ステップ S111、ステップ S113の各々において、現在時刻と変更時刻が一致し ない場合 (各ステップで NO)とは、表示装置の駆動開始時刻が、各々の指定時刻を 既に過ぎて 、るような場合であり、この場合角度調整は行わな 、。  [0036] In each of step S111 and step S113, when the current time does not coincide with the change time (NO in each step), the drive start time of the display device has already passed each designated time, In this case, do not adjust the angle.
[0037] 尚、角度制御テーブル 4は、例えば、ある一定の緯度ごと及びある一定の経度ごと 、又は主要都市の緯度及び経度等に対応する変更時刻が格納されている。従って、 変更時刻はある一定のエリアごとで定められる。例えば、エリア Aとエリア Bが隣り合つ ていて、車両の現在位置がエリア Aにあり、表示部 9が変更時設定角度 (第 2の設定 角度）の状態で走行中にエリア Bに入り、現在時刻がエリア Bにおける変更時刻を過 ぎていた場合は、変更時設定角度力 初期設定角度に戻るよう、所定の角度量分、 制御部 7が角度調整部 8を制御し、表示部 9が駆動されてもよい。  [0037] The angle control table 4 stores, for example, change times corresponding to every certain latitude and every certain longitude, or the latitude and longitude of the main city. Therefore, the change time is determined for each certain area. For example, area A and area B are adjacent to each other, the current position of the vehicle is in area A, and the display unit 9 enters area B while driving with the set angle at change (second set angle) If the current time has exceeded the change time in area B, the control unit 7 controls the angle adjustment unit 8 and the display unit 9 It may be driven.
[0038] 図 7は、表示部 9の具体的な動作の例を示す（ Θ 1 =0度、 Θ 2 = 30度)。図 7は、液 晶ディスプレイなど力も構成された表示部 9が、ナビゲーシヨン装置等の筐体 10に対 し相対的に駆動する様子を示している。傾きの角度の大きさは、 CLOSE (0度)から TILT1、 TILT2、 TILT3、 TILT4 (最大角度）の順である。そして、各角度の差は 5 度であり、 1回の操作による変化量 (角度量）は 10度に設定されている。  FIG. 7 shows an example of specific operation of the display unit 9 (Θ 1 = 0 degrees, Θ 2 = 30 degrees). FIG. 7 shows a state in which a display unit 9 having a force such as a liquid crystal display is driven relative to a housing 10 such as a navigation device. The angle of inclination is from CLOSE (0 degree) to TILT1, TILT2, TILT3, and TILT4 (maximum angle). The difference between the angles is 5 degrees, and the amount of change (angle) by one operation is set to 10 degrees.
[0039] (al)から (a5)は、初期設定角度が TILT2の場合の動作例である（al)。そして、操 作者が眩しさを感じて直射回避ボタンを押すと、午前中の場合太陽は上昇するため 、表示部 9を下に向けるのが好ましいため、表示部 9を所定角度量下向きに移動させ て、表示部 9の設置角度は変更時設定角度 (CLOSE)になる（a2)。  [0039] (al) to (a5) are operation examples when the initial setting angle is TILT2 (al). When the operator feels dazzled and presses the direct shot avoidance button, the sun rises in the morning, so it is preferable to turn the display unit 9 downward, so the display unit 9 is moved downward by a predetermined angle amount. Accordingly, the installation angle of the display unit 9 becomes the set angle (CLOSE) at the time of change (a2).
[0040] その後、太陽の仰角が Θ 2 = 30度の時刻となると、表示部 9の設置角度は初期設 定角度 (TILT2)に戻る (a3)。そして、午後になり操作者が眩しさを感じて直射回避 ボタン 3を操作すると、太陽が下降するために表示部 9を上に向けるのが好ましいた め、表示部 9を所定角度量上向きに移動させて、表示部 9は変更時設定角度 (TILT 4)まで移動する（a4)。そして、太陽の仰角が θ 1 =0度の時刻となると（日没）、表示 部 9の設置角度は初期設定角度 (TILT2)に戻る (a5)。なお、初期設定角度から表 示部 9を特定方向に所定角度量動力せない場合は、特定方向を変更 (例えば上向き を下向きに変える）して動かすようにしてもょ 、。 [0040] Thereafter, when the elevation angle of the sun reaches Θ 2 = 30 degrees, the installation angle of the display unit 9 returns to the initial setting angle (TILT2) (a3). Then, in the afternoon, when the operator feels dazzling and operates the direct shot avoidance button 3, it is preferable to turn the display unit 9 upward because the sun descends, so the display unit 9 is moved upward by a predetermined angle amount. Thus, the display unit 9 moves to the change-time setting angle (TILT 4) (a4). And when the sun ’s elevation angle reaches θ 1 = 0 degrees (sunset), The installation angle of part 9 returns to the initial setting angle (TILT2) (a5). If the display unit 9 cannot be powered by a predetermined angle amount in a specific direction from the default angle, change the specific direction (for example, change the upward direction to the downward direction) and move it.
[0041] 尚、本発明で言う「所定条件」とは、太陽の直射光が操作者の目の方向に反射しな いという条件をいうが、本実施形態では角度制御テーブル 4を用いて、変更時刻とい う形で間接的に与えられている。また、所定条件の決定には数値的に厳密なものは 要求されず、おおよそ一般的、経験的に眩しさを感じなくなる条件が与えられれば、 そのような条件は「所定条件」に含まれる。  [0041] The "predetermined condition" referred to in the present invention is a condition that the direct sunlight is not reflected in the direction of the operator's eyes. In the present embodiment, the angle control table 4 is used, It is given indirectly in the form of modification time. In addition, the determination of the predetermined condition is not required to be numerically strict, and such a condition is included in the “predetermined condition” if a condition that does not make the user feel dazzling in general and experience is given.
[0042] また、操作部 3を、表示部 9の液晶ディスプレイ上に表示形成されたタツチスィッチ 等で構成する場合、必要時、すなわち、操作者が眩しさを感じる時間帯、すなわち上 記所定条件が不成立の間のみ、該スィッチを表示部 9上に表示させてもよい。  [0042] Further, when the operation unit 3 is configured by a touch switch or the like displayed on the liquid crystal display of the display unit 9, when necessary, that is, when the operator feels dazzling, that is, the predetermined condition is The switch may be displayed on the display unit 9 only during failure.
[0043] なお、さらに車両のピッチ角を検出する手段を備え、制御部 7は、ピッチ角の検出 結果に応じて表示部の設置角度を設定してもよい。具体的には、例えば、変更時設 定角度を、車両が水平な位置にいる場合の設定値にピッチ角の検出結果を加え、表 示面 9の地面に対する設置角度を一定としてもよい。  [0043] It should be noted that a means for detecting the pitch angle of the vehicle may further be provided, and the control unit 7 may set the installation angle of the display unit according to the detection result of the pitch angle. Specifically, for example, the setting angle at the time of change may be added to the setting value when the vehicle is in a horizontal position, and the installation angle of the display surface 9 with respect to the ground may be made constant.
[0044] なお、操作者が操作部 3を操作したときに、表示部 9の設定角度を第 2の設定角度 にしていたが、自動で行なうようにしてもよい。この動作例を図 8に基づいて説明する 。操作者が、乗車時または走行中に表示部 9の設置角度を好みの初期設定角度 (第 1の設定角度）に初期設定する。午前中において現在時刻が、角度制御テーブル 4 が保持する月日、位置 (緯度及び経度）に対応した仰角が Θ 1となる変更時刻と一致 すると (ステップ S103 ; YES)、表示部 9の設置角度が、初期設定角度から変更した 変更時設定角度 (第 2の設定角度）になるよう、制御部 7が所定の角度量の分、角度 調整部 8を制御し、表示部 9が駆動される (ステップ S104)。  [0044] Although the setting angle of the display unit 9 is set to the second setting angle when the operator operates the operation unit 3, the setting angle may be automatically set. An example of this operation will be described with reference to FIG. The operator initially sets the installation angle of the display unit 9 to a desired initial setting angle (first setting angle) while riding or traveling. If the current time in the morning coincides with the change date when the elevation angle corresponding to the date and position (latitude and longitude) held in the angle control table 4 becomes Θ 1 (step S103; YES), the installation angle of the display unit 9 The control unit 7 controls the angle adjustment unit 8 by a predetermined angle amount so that the display unit 9 is driven so that the change angle is changed from the initial setting angle (second setting angle). Step S104).
[0045] さらに、午前中において現在時刻力 角度制御テーブル 4が保持する月日、位置（ 緯度及び経度）に対応した仰角が Θ 2となる変更時刻と一致すると (ステップ S105 ; YES)、表示部 9の設置角度が、ステップ S104で設定された変更時設定角度力も初 期設定角度に戻るよう、所定の角度量の分、制御部 7が角度調整部 8を制御し、表示 部 9が駆動される (ステップ S 106)。 [0046] 次いで午後になり、現在時刻が角度制御テーブル 4が保持する月日、位置 (緯度 及び経度）に対応した仰角が再び Θ 2となる変更時刻と一致すると (ステップ S107 ; YES)、表示部 9の設置角度がステップ S 105で設定した初期設定角度力も変更時 設定角度になるよう、制御部 7が所定の角度量の分、角度調整部 8を制御し、表示部 9が駆動される（ステップ S 108)。 [0045] Further, in the morning, when the elevation time corresponding to the date and position (latitude and longitude) held in the current time and angle control table 4 coincides with the change time at which Θ2 becomes Θ2 (step S105; YES), the display unit The control unit 7 controls the angle adjustment unit 8 and the display unit 9 is driven so that the installation angle of 9 is returned to the initial setting angle by the set angular force at the time of change set in step S104. (Step S106). [0046] Next, in the afternoon, when the current time coincides with the change time at which the elevation angle corresponding to the date and position (latitude and longitude) held in the angle control table 4 becomes Θ 2 again (step S107; YES), the display The control unit 7 controls the angle adjustment unit 8 by a predetermined amount of angle so that the display unit 9 is driven so that the initial setting angular force set in step S 105 becomes the setting angle at the time of change. (Step S108).
[0047] さらに、現在時刻が、角度制御テーブル 4が保持する月日、位置 (緯度及び経度） に対応した仰角が再び 0 1となる変更時刻と一致すると (ステップ S109 ; YES)、表 示部 9の設置角度が、ステップ S108で設定された変更時設定角度から初期設定角 度に戻るよう、所定の角度量の分、制御部 7が角度調整部 8を制御し、表示部 9が駆 動される（ステップ S 110)。  [0047] Further, when the current time coincides with the change time at which the elevation angle corresponding to the date and position (latitude and longitude) held in the angle control table 4 becomes 0 1 again (step S109; YES), the display unit The control unit 7 controls the angle adjustment unit 8 and the display unit 9 is driven by a predetermined angle amount so that the installation angle of 9 returns from the setting angle at the time of change set in step S108 to the initial setting angle. (Step S110).
[0048] 尚、ステップ S103、ステップ S105、ステップ S107およびステップ S109の各々に おいて、現在時刻と変更時刻が一致しない場合 (各ステップで NO)とは、表示装置 の駆動開始時刻が、各々の指定時刻を既に過ぎているような場合であり、この場合 角度調整は行わない。また、表示部 9が第 2の設定角度の時に操作部 3を操作すると 、第 1の設定角度になるようにしてぉ ヽても力まわな!/、。  [0048] In step S103, step S105, step S107, and step S109, when the current time does not match the change time (NO in each step), the drive start time of the display device is This is the case when the specified time has already passed. In this case, the angle is not adjusted. In addition, if the operation unit 3 is operated when the display unit 9 is at the second set angle, it is possible to turn it to the first set angle.
[0049] 以上のように、本発明の車載用表示装置では、太陽光の方位と高度と車両の進行 方向に応じてディスプレイの角度調整、バックライト輝度調整および Zまたは色調調 整を行うといった複雑な計算を行なうことはしない。本発明の車載用表示装置では、 あらかじめ格納された時刻情報、位置情報などを含むデータに基づき表示部の角度 を自動調整する。従って、煩雑な動作をせず、簡易かつ安価な制御及び構成にて太 陽光の映りこみ及び反射を軽減し、表示部の視認性を確保することが可能となる。  As described above, in the in-vehicle display device of the present invention, the display angle adjustment, backlight brightness adjustment, and Z or color adjustment are performed in accordance with the direction and altitude of sunlight and the traveling direction of the vehicle. Do not make any intensive calculations. In the in-vehicle display device of the present invention, the angle of the display unit is automatically adjusted based on data including time information and position information stored in advance. Therefore, it is possible to reduce the reflection and reflection of sunlight with simple and inexpensive control and configuration without complicated operation and to ensure the visibility of the display unit.
