以上のように構成されるエコ運転状態表示装置１の動作について説明する。エコ運転状態表示装置１は、例えばエンジンキー等により車両が始動すると、車両情報検出部２０により車両情報であるエンジン回転数、車両速度、及び燃料消費量の検出を開始する。車両情報検出部２０により検出された車両情報の検出信号は、制御部３０に送信される。制御部３０は、受信した検出信号に基づき、エコ運転状態情報であるエンジン回転数及び燃費を算出し、表示部１０に各エコ運転状態情報の値に応じた制御信号を送信する。回転指示部１２の指針１２ａは、駆動部により回転して、制御部３０からの制御信号が示すエンジン回転数に対応する指標を指示する。また、燃費表示部１３は、ＬＥＤ１３ａを点灯させて、制御部３０からの制御信号が示す燃費に対応する指標を指示する。 The operation of the eco-drive state display device 1 configured as described above will be described. For example, when the vehicle is started by an engine key or the like, the eco-drive state display device 1 starts detection of engine speed, vehicle speed, and fuel consumption, which are vehicle information, by the vehicle information detection unit 20. A vehicle information detection signal detected by the vehicle information detection unit 20 is transmitted to the control unit 30. Based on the received detection signal, the control unit 30 calculates the engine speed and fuel consumption, which are eco-driving state information, and transmits a control signal corresponding to the value of each eco-driving state information to the display unit 10. The pointer 12a of the rotation instructing unit 12 is rotated by the driving unit, and indicates an index corresponding to the engine speed indicated by the control signal from the control unit 30. In addition, the fuel consumption display unit 13 turns on the LED 13a to indicate an index corresponding to the fuel consumption indicated by the control signal from the control unit 30.
以上説明したように、本実施形態に係るエコ運転状態表示装置１において、エコ運転状態情報の一例であるエンジン回転数及び燃費を表示する際に、回転指示部１２及び燃費指示部１３が共通のスケールである指標部１１を指示する。このように１つの指標部を用いて複数のエコ運転状態情報を表示することができるため、省スペース、且つシンプルな表示が可能であり、視認性を向上させることができる。 As described above, in the eco-driving state display device 1 according to the present embodiment, when displaying the engine speed and fuel consumption, which are examples of the eco-driving state information, the rotation instruction unit 12 and the fuel consumption instruction unit 13 are common.

また、本実施形態に係るエコ運転状態表示装置１においては、低域側指標部１１ａの指標間隔が、高域側指標部１１ｂの指標間隔よりも大きい。このため、低域側指標部１１ａの指標のみを用いて表示される燃費の視認性を向上させることができる。また、低域側指標部１１ａの指標の数値範囲がエンジン回転数の実用範囲に相当するため、エンジン回転数の視認性を向上させることができる。 In the eco-drive state display device 1 according to the present embodiment, the index interval of the low frequency side indicator unit 11a is larger than the index interval of the high frequency side index unit 11b. For this reason, the visibility of the fuel consumption displayed only using the parameter | index of the low-frequency side parameter | index part 11a can be improved. In addition, since the numerical range of the index of the low-frequency side indicator portion 11a corresponds to the practical range of the engine speed, the visibility of the engine speed can be improved.
また、本実施形態に係るエコ運転状態表示装置１において、燃費指示部１３は指標部１１の指標の配列方向に沿って伸縮する帯状の指示部であるため、回転指示部１２の指針１２ａによるエンジン回転数の表示と混同することなく、燃費を表示することができる。したがって、エンジン回転数と燃費の視認性を向上させることができる。 In the eco-driving state display device 1 according to the present embodiment, the fuel efficiency indicator 13 is a belt-like indicator that expands and contracts along the indicator arrangement direction of the indicator 11, so that the engine by the pointer 12a of the rotation indicator 12 The fuel consumption can be displayed without being confused with the display of the rotational speed.

また、エコ運転状態情報として、アクセル開度と、燃料噴射率を表示してもよい。図４（ｄ）に、アクセル開度と燃料噴射率を表示する表示部１０の一例を示す。図４（ｄ）に示す表示部１０は、指標部１１と、アクセル開度指示部１４と、燃料噴射率指示部１６とを有する。燃料噴射率指示部１６は、指標部１１の指標を指示することで車両の燃料噴射率を示すものである。燃料噴射率指示部１６は、上記の実施形態における燃費指示部１３と同様に構成されている。 Moreover, you may display an accelerator opening and a fuel injection rate as eco-operation state information. FIG. 4D shows an example of the display unit 10 that displays the accelerator opening and the fuel injection rate. The display unit 10 illustrated in FIG. 4D includes an index unit 11, an accelerator opening instruction unit 14, and a fuel injection rate instruction unit 16. The fuel injection rate instruction unit 16 indicates the fuel injection rate of the vehicle by instructing the index of the index unit 11. The fuel injection rate instruction unit 16 is configured in the same manner as the fuel consumption instruction unit 13 in the above embodiment.
また、エコ運転状態情報として、アクセル開度と、低燃費走行採点を表示してもよい。ここで、低燃費走行採点とは、車両の走行状態がどれだけ低燃費となる走行状態に近いかを点数で評価したものである。低燃費走行採点Ｐの具体的な計算方法の一例を下記式に示す。
図４（ｅ）に、アクセル開度と低燃費走行採点を表示する表示部１０の一例を示す。図４（ｅ）に示す表示部１０は、アクセル開度指示部１４と、低燃費走行採点指示部１７とを有する。低燃費走行採点指示部１７は、指標部１１の指標を指示することで車両の低燃費走行採点を示すものである。低燃費走行採点指示部１７は、上記の実施形態における燃費指示部１３と同様に構成されている。
Further, as the eco-driving state information, an accelerator opening degree and a fuel-efficient driving score may be displayed. Here, the low fuel consumption traveling scoring is an evaluation of how close the vehicle traveling state is to a traveling state where the fuel consumption is low. An example of a specific calculation method of the low fuel consumption traveling score P is shown in the following formula.
FIG. 4 (e) shows an example of the display unit 10 that displays the accelerator opening and the low fuel consumption travel scoring. The display unit 10 illustrated in FIG. 4E includes an accelerator opening degree instruction unit 14 and a low fuel consumption travel scoring instruction unit 17. The low fuel consumption travel scoring instruction unit 17 indicates the low fuel consumption travel scoring of the vehicle by instructing the index of the index unit 11. The low fuel consumption traveling scoring instruction unit 17 is configured in the same manner as the fuel consumption instruction unit 13 in the above embodiment.
また、上記の実施形態に係るエコ運転状態表示装置１においては、駆動部により指針を回転させて指標を指示することによりエンジン回転数を表示するアナログ式の表示方法を用いている。しかし、表示方法はこれに限られず、例えば、指標部や各種の指示部の全てまたは一部を液晶や電界発光素子等のフラットディスプレイパネルを用いた画像表示としてもよい。 Moreover, in the eco-drive state display device 1 according to the above-described embodiment, an analog display method is used in which the engine speed is displayed by instructing an index by rotating the pointer by the drive unit. However, the display method is not limited to this, and for example, all or a part of the indicator unit and various instruction units may be displayed using a flat display panel such as a liquid crystal or an electroluminescent element.
