　表示パネル１１は、図１に示す表示セグメント群２Ａ、２Ｂを構成し、グラフィック表示を行うカラーＴＦＴ液晶パネル（ＴＦＴ－ＬＣＤ）で構成される。また、グラフィックコントローラ１３、Ｘドライバ２１、Ｙドライバ２３及びＣＰＵ１５は、表示制御部５を構成する。 The display panel 11 comprises display segment groups 2A and 2B shown in FIG. 1, and is composed of a color TFT liquid crystal panel (TFT-LCD) that performs graphic display. In addition, the graphic controller 13, the X driver 21, the Y driver 23, and the CPU 15 constitute a display control unit 5.
　この表示パネル１１は、水平同期信号に応じた電圧を印加するＸドライバ２１および垂直同期信号に応じた電圧を印加するＹドライバ２３によって駆動される。 The display panel 11 is driven by an X driver 21 that applies a voltage according to a horizontal synchronizing signal and a Y driver 23 that applies a voltage according to a vertical synchronizing signal.
　また、表示パネル１１には、ＬＣＤ電源２８からの印加電圧によって照度が調節されるバックライト１１ａ（照明部）が設けられている。バックライト１１ａには、例えば、ＬＥＤ（Light Emitting Diode）、またはＥＬ（Electro Luminescence）照明を用いることができる。このバックライト１１ａの照度を調節することで、表示パネル１１に表示される画像（表示セグメント３ａ～３ｅ、４ａ～４ｅ）の輝度が変更される。 Further, the display panel 11 is provided with a backlight 11a (illumination unit) whose illuminance is adjusted by an applied voltage from the LCD power supply 28. As the backlight 11a, for example, LED (Light-Emitting-Diode) or EL (Electro-Luminescence) illumination can be used. By adjusting the illuminance of the backlight 11a, the luminance of the images (display segments 3a to 3e, 4a to 4e) displayed on the display panel 11 is changed.
　グラフィックコントローラ１３は、表示セグメントのＲＧＢ画像データなど各種の画像データが格納されるフレームメモリ１３ａを有する。グラフィックコントローラ１３は、このフレームメモリ１３ａに格納された画像データを表示パネル１１に伝送する。また、グラフィックコントローラ１３は、Ｘドライバ２１に水平同期信号を出力し、Ｙドライバ２３に垂直同期信号を出力する。 The graphic controller 13 has a frame memory 13a for storing various image data such as RGB image data of the display segment. The graphic controller 13 transmits the image data stored in the frame memory 13a to the display panel 11. Further, the graphic controller 13 outputs a horizontal synchronization signal to the X driver 21 and outputs a vertical synchronization signal to the Y driver 23.
　また、グラフィックコントローラ１３は、ＣＰＵ１５からの指示に従って、画像データの値を変更することによりＬＣＤ透過率や色度を調節し、夜間点灯時、表示パネル１１に表示される表示セグメント３ａ～３ｆ、４ａ～４ｆの表示を調整する。ＬＣＤ透過率や色度を用いることで各表示セグメントの表示色や濃淡の調整が容易となる。 Further, the graphic controller 13 adjusts the LCD transmittance and chromaticity by changing the value of the image data in accordance with an instruction from the CPU 15, and displays the display segments 3a to 3f and 4a displayed on the display panel 11 at the time of lighting at night. Adjust the display of ~ 4f. By using the LCD transmittance and chromaticity, the display color and shading of each display segment can be easily adjusted.
　ＣＰＵ１５には、ＥＥＰＲＯＭ２５が外付けされている。ＣＰＵ１５は、ＥＥＰＲＯＭ２５に格納された表示制御プログラムを実行し、表示パネル１１に表示される表示セグメント３ａ～３ｅ、４ａ～４ｅ等の画像データを生成し、グラフィックコントローラ１３に伝送する。 The EEPROM 15 is externally attached to the CPU 15. The CPU 15 executes a display control program stored in the EEPROM 25, generates image data such as display segments 3a to 3e and 4a to 4e displayed on the display panel 11, and transmits them to the graphic controller 13.
　Ｉ／Ｏインタフェース１７には、バッテリ（電源）５１のプラス（＋）に接続されたイグニッションスイッチ（ＩＧＮ）５２が接続され、イグニッションスイッチ５２のＯＮ／ＯＦＦが入力される。 The ignition switch (IGN) 52 connected to the plus (+) of the battery (power source) 51 is connected to the I / O interface 17 and ON / OFF of the ignition switch 52 is input.
　また、Ｉ／Ｏインタフェース１８には、トルクデータ等が入力される。 Also, torque data and the like are input to the I / O interface 18.
　また、ＣＰＵ１５には、バッテリ５１に接続されたＣＰＵ電源２７から電力が供給される。同様に、表示パネル１１には、バッテリ５１に接続されたＬＣＤ電源２８から電力が供給される。ＬＣＤ電源２８は、ＴＦＴ液晶１１の各電極に電圧を印加するとともに、バックライト１１ａに電圧を印加する。 Further, power is supplied to the CPU 15 from a CPU power source 27 connected to the battery 51. Similarly, power is supplied to the display panel 11 from the LCD power source 28 connected to the battery 51. The LCD power supply 28 applies a voltage to each electrode of the TFT liquid crystal 11 and also applies a voltage to the backlight 11a.
（計器盤の構成例）
　図３は、本実施の形態に係る車両用表示装置１を備え、自動車等の車両の運転席の前面に配置される計器盤２００の構成例を示す平面図である。 (Example of instrument panel configuration)
FIG. 3 is a plan view illustrating a configuration example of an instrument panel 200 that includes the vehicle display device 1 according to the present embodiment and is disposed in front of a driver's seat of a vehicle such as an automobile.
　図３に示す計器盤２００においては、中央部に本実施の形態に係る車両用表示装置１が配置され、その左側に円形の速度計（スピードメータ）２０１が配置され、右側に円形の回転計（タコメータ）２０２が配置されている。また、ターンＬ表示部２０３、ターンＲ表示部２０４等が配置されている。 In the instrument panel 200 shown in FIG. 3, the vehicle display device 1 according to the present embodiment is disposed at the center, a circular speedometer (speedometer) 201 is disposed on the left side, and a circular tachometer is disposed on the right side. A (tachometer) 202 is arranged. Further, a turn L display unit 203, a turn R display unit 204, and the like are arranged.
　図３に示す車両用表示装置１は、中央部に車両のヨーモーメントの状態を示すヨーモーメント表示部３００が配置され、このヨーモーメント表示部３００の左右にトルクの配分状態を示す表示セグメント群２Ａ（２Ａ１、２Ａ２）、２Ｂ（２Ｂ１、２Ｂ２）が配置されている。 The vehicle display device 1 shown in FIG. 3 has a yaw moment display unit 300 indicating the state of the yaw moment of the vehicle at the center, and a display segment group 2A indicating the torque distribution state on the left and right of the yaw moment display unit 300. (2A1, 2A2), 2B (2B1, 2B2) are arranged.
　図３に示す例では、左側の上方の表示セグメント群２Ａ１の表示セグメント３ａと、右側の上方の表示セグメント群２Ａ２の表示セグメント３ｂとが点灯されている状態を示している。 3 shows a state where the display segment 3a of the upper left display segment group 2A1 and the display segment 3b of the upper right display segment group 2A2 are lit.
　ここで、図４を参照して、表示セグメント群２Ａ（２Ａ１、２Ａ２）、２Ｂ（２Ｂ１、２Ｂ２）における表示セグメント３ａ～３ｆ、４ａ～４ｆの点灯態様（点灯パターン）について説明する。 Here, with reference to FIG. 4, lighting modes (lighting patterns) of the display segments 3a to 3f and 4a to 4f in the display segment groups 2A (2A1, 2A2) and 2B (2B1, 2B2) will be described.
　図４（ａ）は、表示セグメント群２Ａ（２Ａ１、２Ａ２）における表示セグメント３ａ～３ｆの点灯位置の遷移状態を示す。 FIG. 4A shows a transition state of the lighting positions of the display segments 3a to 3f in the display segment group 2A (2A1, 2A2).
　そして、図１に示す表示制御部５の制御により、駆動輪に発生しているトルク量がプラスの場合には、所定の基準部１０１から上方向に配置された表示セグメント群２Ａのうち、トルク量に対応する位置の一つの表示セグメント３ａ～３ｆが選択されて点灯される。この場合、トルク量が大きいほど上方向に位置する表示セグメント３ａ～３ｆが選択されて点灯される。 When the amount of torque generated in the drive wheels is positive by the control of the display control unit 5 shown in FIG. 1, the torque in the display segment group 2 </ b> A arranged upward from the predetermined reference unit 101. One display segment 3a-3f at a position corresponding to the quantity is selected and lit. In this case, as the amount of torque increases, the display segments 3a to 3f positioned in the upward direction are selected and turned on.
　そして、図４（ａ）に示す例において、表示セグメント３ａ→３ｂの変化量Ｖ１、表示セグメント３ａ→３ｃの変化量Ｖ２、表示セグメント３ａ→３ｄの変化量Ｖ３、表示セグメント３ａ→３ｅの変化量Ｖ４、表示セグメント３ａ→３ｆの変化量Ｖ５が、Ｖ１＜Ｖ２＜Ｖ３＜Ｖ４＜Ｖ５であるとする。この場合に、表示セグメント３ｂ～３ｆの表示色は、変化量Ｖ１～Ｖ５が大きいほど濃くなるように変化される。即ち、３ｂ→３ｃ→３ｄ→３ｅ→３ｆとトルクの変化量が大きくなるにつれて、例えば、薄い青色→青色→濃い青色などというように表示色が徐々に濃くなるように変化される。 In the example shown in FIG. 4A, the change amount V1 of the display segment 3a → 3b, the change amount V2 of the display segment 3a → 3c, the change amount V3 of the display segment 3a → 3d, and the change amount of the display segment 3a → 3e. It is assumed that the change amount V5 of V4 and display segment 3a → 3f is V1 <V2 <V3 <V4 <V5. In this case, the display colors of the display segments 3b to 3f are changed so as to become darker as the change amounts V1 to V5 are larger. That is, as the amount of change in torque increases from 3b → 3c → 3d → 3e → 3f, for example, the display color is changed so as to gradually darken, such as light blue → blue → dark blue.
　なお、駆動輪に発生しているトルクの変化量に応じて点灯色を赤系統などから青系統や緑系統等の寒色系の色にグラデーションで変化させるようにしてもよい。 It should be noted that the lighting color may be changed from a red system or the like to a cold system color such as a blue system or a green system in a gradation according to the amount of change in torque generated in the drive wheels.
　図４（ｂ）は、表示セグメント群２Ｂ（２Ｂ１、２Ｂ２）における表示セグメント４ａ～４ｆの点灯位置の遷移状態を示す。 FIG. 4B shows a transition state of the lighting positions of the display segments 4a to 4f in the display segment group 2B (2B1, 2B2).
　そして、図１に示す表示制御部５の制御により、駆動輪に発生しているトルク量がマイナスの場合には、所定の基準部１０１から下方向に配置された表示セグメント群２Ｂのうち、トルク量に対応する位置の一つの表示セグメント４ａ～４ｆが選択されて点灯される。この場合、トルク量のマイナス量が大きいほど下方向に位置する表示セグメント４ａ～４ｆが選択されて点灯される。 When the amount of torque generated in the drive wheels is negative by the control of the display control unit 5 shown in FIG. 1, the torque of the display segment group 2 </ b> B arranged downward from the predetermined reference unit 101. One display segment 4a-4f at a position corresponding to the quantity is selected and lit. In this case, the display segments 4a to 4f positioned in the downward direction are selected and lighted as the minus amount of the torque amount increases.
　そして、図４（ｂ）に示す例において、表示セグメント４ａ→４ｂの変化量Ｖ１、表示セグメント４ａ→４ｃの変化量Ｖ２、表示セグメント４ａ→４ｄの変化量Ｖ３、表示セグメント４ａ→４ｅの変化量Ｖ４、表示セグメント４ａ→４ｆの変化量Ｖ５が、Ｖ１＜Ｖ２＜Ｖ３＜Ｖ４＜Ｖ５であるとする。この場合に、表示セグメント４ｂ～４ｆの表示色は、変化量Ｖ１～Ｖ５が大きいほど濃くなるように変化される。即ち、４ｂ→４ｃ→４ｄ→４ｅ→４ｆとトルクの変化量が大きくなるにつれて、例えば、薄い赤色→赤色→濃い赤色などというように表示色が徐々に濃くなるように変化される。 In the example shown in FIG. 4B, the change amount V1 of the display segment 4a → 4b, the change amount V2 of the display segment 4a → 4c, the change amount V3 of the display segment 4a → 4d, and the change amount of the display segment 4a → 4e. It is assumed that the change amount V5 of V4 and display segment 4a → 4f is V1 <V2 <V3 <V4 <V5. In this case, the display colors of the display segments 4b to 4f are changed to become darker as the change amounts V1 to V5 are larger. That is, as the amount of change in torque increases from 4b → 4c → 4d → 4e → 4f, the display color is changed to gradually darken, for example, light red → red → dark red.
　なお、駆動輪に発生しているトルクの変化量に応じて点灯色を青系統などから赤系統や橙色系統等の強調色（あるいは暖色系の色）にグラデーションで変化させるようにしてもよい。 It should be noted that the lighting color may be changed in gradation from a blue system or the like to an emphasized color (or warm color system) such as a red system or an orange system according to the amount of change in torque generated in the drive wheels.
（トルク等の表示例）
　図５は、本実施の形態に係る車両用表示装置１におけるトルク等の表示例を示す説明図である。 (Example of torque display)
FIG. 5 is an explanatory diagram showing a display example of torque and the like in the vehicle display device 1 according to the present embodiment.
　図５（ａ）は、右側に図示するように、車両ＣがＤ１方向に直線走行している場合のトルク等の表示例である。 FIG. 5A is a display example of torque and the like when the vehicle C is traveling straight in the direction D1, as illustrated on the right side.
　図５（ａ）に示す表示例では、モーメントの状態を示すモーメント表示部３００の左右に、左車輪および右車輪に発生するトルクが、駆動側の表示セグメント群２Ａ１の表示セグメント３ｂと、駆動側の表示セグメント群２Ａ２の表示セグメント３ｂとの点灯によって表示されている。即ち、車両Ｃが駆動されるＤ１方向に直線走行している場合の左右車輪のトルク差は「０」となるので、上述のような表示態様となる。 In the display example shown in FIG. 5A, the torque generated on the left wheel and the right wheel on the left and right of the moment display unit 300 indicating the state of the moment is the display segment 3b of the display segment group 2A1 on the drive side and the drive side. Is displayed by lighting the display segment 3b of the display segment group 2A2. That is, the torque difference between the left and right wheels when the vehicle C is traveling straight in the direction D1 is “0”, so the display mode is as described above.
　図５（ｂ）は、右側に図示するように、車両Ｃに反時計回り（矢印Ｍ１方向）のモーメントが生じた場合のトルク量等の表示例である。 FIG. 5B is a display example of a torque amount or the like when a counterclockwise moment (in the direction of the arrow M1) is generated in the vehicle C as illustrated on the right side.
　図５（ｂ）に示す表示例では、モーメントの状態を示すモーメント表示部３００の左右に、左車輪および右車輪に発生するトルクが、制動側の表示セグメント群２Ｂ１の表示セグメント４ｄと、制動側の表示セグメント群２Ｂ２の表示セグメント４ｂとの点灯によって表示されている。即ち、例えば車両Ｃがブレーキをかけながら右方向に旋回している場合には、左車輪の制動力が右車輪の制動力より大きい状態となるので、上述のような表示態様となる。 In the display example shown in FIG. 5B, the torques generated on the left and right wheels on the left and right of the moment display section 300 indicating the state of the moment are the display segment 4d of the display segment group 2B1 on the braking side and the braking side. Is displayed by lighting the display segment 4b of the display segment group 2B2. That is, for example, when the vehicle C is turning to the right while applying a brake, the braking force of the left wheel is greater than the braking force of the right wheel, so the display mode is as described above.
　図５（ｃ）は、右側に図示するように、車両Ｃに時計回り（矢印Ｍ２方向）のモーメントが生じた場合のトルク量等の表示例である。 FIG. 5C is a display example of the torque amount and the like when a clockwise (in the direction of arrow M2) moment is generated in the vehicle C, as shown on the right side.
　図５（ｃ）に示す表示例では、モーメントの状態を示すモーメント表示部３００の左右に、左車輪および右車輪に発生するトルクが、駆動側の表示セグメント群２Ａ１の表示セグメント３ａと、制動側の表示セグメント群２Ａ２の表示セグメント３ｂとの点灯によって表示されている。即ち、例えば車両Ｃがアクセルオンの状態で右方向に旋回している場合には、左車輪のトルクが右車輪のトルクより大きい状態となるので、上述のような表示態様となる。 In the display example shown in FIG. 5C, the torque generated on the left wheel and the right wheel on the left and right of the moment display section 300 indicating the state of the moment is the display segment 3a of the display segment group 2A1 on the driving side and the braking side. Is displayed by lighting the display segment 3b of the display segment group 2A2. That is, for example, when the vehicle C is turning right with the accelerator on, the torque of the left wheel is greater than the torque of the right wheel, so the display mode is as described above.
　なお、図５における表示態様では、表示セグメント群２Ａ（２Ａ１、２Ａ２）、２Ｂ（２Ｂ１、２Ｂ２）における表示セグメント３ａ～３ｆおよび４ａ～４ｆは、上下方向の直線状に点灯位置が遷移する。これに限らず、円弧状や所定の曲線に沿って点灯位置が遷移するようにしてもよい。 In the display mode in FIG. 5, the lighting positions of the display segments 3a to 3f and 4a to 4f in the display segment groups 2A (2A1, 2A2) and 2B (2B1, 2B2) transition in a straight line in the vertical direction. However, the present invention is not limited to this, and the lighting position may transition along an arc or a predetermined curve.
（表示処理制御）
　図６に示すフローチャートを参照して、本実施の形態に係る車両用表示装置１で実行される表示制御処理の処理手順の例について説明する。 (Display processing control)
With reference to the flowchart shown in FIG. 6, the example of the process sequence of the display control process performed with the display apparatus 1 for vehicles which concerns on this Embodiment is demonstrated.
　なお、この表示制御処理は、駆動輪ごと（例えば、二輪駆動の場合には左右駆動輪、四輪駆動の場合には各駆動輪ごと）に行われる。 This display control process is performed for each drive wheel (for example, left and right drive wheels in the case of two-wheel drive, and each drive wheel in the case of four-wheel drive).
　まず、ステップＳ１０では、車両が備える所定のセンサ等からトルクデータを取得してステップＳ１１に移行する。 First, in step S10, torque data is acquired from a predetermined sensor or the like provided in the vehicle, and the process proceeds to step S11.
　ステップＳ１１では、トルクデータに基いて車両が停止しているか否かが判定され、「Ｙｅｓ」の場合にはステップＳ１０に戻り、「Ｎｏ」の場合にはステップＳ１２に移行する。 In step S11, it is determined whether or not the vehicle is stopped based on the torque data. If “Yes”, the process returns to step S10, and if “No”, the process proceeds to step S12.
　ステップＳ１２では、トルクは駆動側か否かが判定され、「Ｙｅｓ」の場合にはステップＳ１３に移行して、駆動側の表示セグメント群２Ａ（２Ａ１、２Ａ２）において、トルク量に対応する位置の表示セグメント３ａ～３ｆを選択して点灯し、処理を終了する。 In step S12, it is determined whether or not the torque is on the drive side. If “Yes”, the process proceeds to step S13, and the position of the display segment group 2A (2A1, 2A2) on the drive side corresponds to the torque amount. The display segments 3a to 3f are selected and turned on, and the process ends.
　一方、ステップＳ１２で「Ｎｏ」の場合には、ステップＳ１４に移行してトルクは制動側であるとしてステップＳ１５に移行する。 On the other hand, if “No” in step S12, the process proceeds to step S14, and the process proceeds to step S15 assuming that the torque is on the braking side.
　ステップＳ１５では、制動側の表示セグメント群２Ｂ（２Ｂ１、２Ｂ２）において、トルク量に対応する位置の表示セグメント４ａ～４ｆを選択して点灯し、処理を終了する。 In step S15, in the display segment group 2B (2B1, 2B2) on the braking side, the display segments 4a to 4f at positions corresponding to the torque amount are selected and turned on, and the process is terminated.
　以上の処理手順を各駆動輪ごとに行うことにより、図５に示すようなトルクの表示態様を実現することができる。 By performing the above processing procedure for each drive wheel, a torque display mode as shown in FIG. 5 can be realized.
　これにより、車輪のトルク状態を視覚的に瞬時に把握することが可能となる。 This makes it possible to visually grasp the torque state of the wheel instantaneously.
（比較例）
　図７を参照して、比較例に係る車両用表示装置の表示態様の例について簡単に説明する。 (Comparative example)
With reference to FIG. 7, the example of the display mode of the display apparatus for vehicles which concerns on a comparative example is demonstrated easily.
　図７（ａ）に示す比較例では、トルク量を棒グラフのように表示面積で表している。また、図７（ｂ）に示す比較例では、トルク量を点灯される表示セグメントの数で表している。 In the comparative example shown in FIG. 7A, the torque amount is represented by a display area like a bar graph. In the comparative example shown in FIG. 7B, the torque amount is represented by the number of display segments to be lit.
　何れの比較例においても、車両の運転者は、トルク量を把握するために面積や表示セグメントの数を認識する必要があり、トルク量の把握に若干時間を要する。 In any of the comparative examples, the driver of the vehicle needs to recognize the area and the number of display segments in order to grasp the torque amount, and it takes some time to grasp the torque amount.
　これに対して、本実施の形態に係る車両用表示装置１では、図５に示すように、トルク量のピーク位置に相当する表示セグメントのみを点灯させているので、車両の運転者は、トルク量を瞬時に把握することができるというメリットがある。また、表示セグメントの色や濃度を表示セグメントの位置により変化させた場合には、さらに、トルク量の把握が容易になる。 On the other hand, in the vehicle display device 1 according to the present embodiment, as shown in FIG. 5, only the display segment corresponding to the peak position of the torque amount is lit, so that the driver of the vehicle There is an advantage that the amount can be grasped instantly. Further, when the color and density of the display segment are changed depending on the position of the display segment, it is further easy to grasp the torque amount.
　以上、本発明の車両用表示装置を図示の実施形態に基づいて説明したが、本発明はこれに限定されるものではなく、各部の構成は、同様の機能を有する任意の構成のものに置き換えることができる。
  The vehicle display device of the present invention has been described based on the illustrated embodiment, but the present invention is not limited to this, and the configuration of each part is replaced with an arbitrary configuration having the same function. be able to.
