Description

本発明は、平均燃費，走行可能距離，外気温度などの車両情報を表示する車両情報表示装置において、車両運転を妨げないようにしつつ、車両運転者の認識度を向上させる技術に関する。   The present invention relates to a technology for improving a vehicle driver's recognition level in a vehicle information display device that displays vehicle information such as an average fuel consumption, a travelable distance, and an outside air temperature without disturbing the vehicle driving.

近年、一部の車両において、ダッシュボードに設置されたコンビネーションメータに、平均燃費，走行可能距離，外気温度などの車両情報を表示する車両情報表示装置が併設されたものが実用化されている。車両運転者が車両情報を認識するとき、車速が高速な場合と低速な場合とでは、注視できる時間が異なる。即ち、車速が低速であれば余裕があるため、車両情報を注視できる時間が比較的長く、標準的なポイント（大きさ）で表示される標準数字を容易に認識することができる。一方、車速が高速であれば余裕が少ないため、車両情報を注視できる時間が短く、標準数字を認識することが困難である。このため、車両運転を妨げないようにすべく、特開２００４−２３４１０７号公報（特許文献１）に記載されるように、車両走行中には、車両情報を表示しないようにする技術が提案されている。
特開２００４−２３４１０７号公報 In recent years, in some vehicles, a combination meter installed on a dashboard is provided with a vehicle information display device that displays vehicle information such as average fuel consumption, travelable distance, and outside air temperature. When the vehicle driver recognizes the vehicle information, the gazeable time differs depending on whether the vehicle speed is high or low. That is, since there is room if the vehicle speed is low, the time during which the vehicle information can be watched is relatively long, and the standard numbers displayed with standard points (sizes) can be easily recognized. On the other hand, if the vehicle speed is high, there is little room, so the time during which the vehicle information can be watched is short, and it is difficult to recognize standard numbers. For this reason, in order not to interfere with vehicle driving, a technique for preventing vehicle information from being displayed while the vehicle is running has been proposed as described in Japanese Patent Application Laid-Open No. 2004-234107 (Patent Document 1). ing.
JP 2004-234107 A

しかしながら、実際の車両運転においては、例えば、高速道路走行中に走行可能距離を確認する必要性があるため、車速の高低にかかわらず、車両情報を参照しなければならない実情が見受けられる。また、車速が高速であるにもかかわらず、車両情報を一見して認識し難い標準数字で表示すると、車両運転者がその数字を注視してしまい、車両運転を妨げてしまうおそれもある。なお、車速の高低だでけはなく、運転負荷に密接に関連する操舵操作においても、同様な問題が発生するおそれがある。   However, in actual vehicle driving, for example, since it is necessary to check the travelable distance during traveling on an expressway, there is a situation in which vehicle information must be referred to regardless of whether the vehicle speed is high or low. Moreover, even if the vehicle speed is high, if the vehicle information is displayed with standard numbers that are difficult to recognize at a glance, the vehicle driver may watch the numbers and hinder the vehicle operation. It should be noted that the same problem may occur in a steering operation closely related to the driving load as well as the vehicle speed.

そこで、本発明は以上のような従来の問題点に鑑み、車両の運転負荷と密接に関連する車速や操舵角に応じて、車両情報の表示形式を順次変更することで、車両運転を妨げないようにしつつ、車両運転者の認識度を向上させた車両情報表示装置を提供することを目的とする。   Therefore, in view of the conventional problems as described above, the present invention does not hinder vehicle driving by sequentially changing the display format of the vehicle information according to the vehicle speed and the steering angle closely related to the driving load of the vehicle. Thus, an object of the present invention is to provide a vehicle information display device that improves the recognition degree of a vehicle driver.

このため、本発明に係る車両情報表示装置では、車両情報を表示する表示手段と、車両運転者の運転負荷を判定する運転負荷判定手段と、運転負荷に応じて車両情報の表示形式を順次変更する表示形式変更手段と、を含んで構成されたことを特徴とする。
ここで、車両情報の表示形式は、人間にとって認識し易いものに順次変更すべく、標準数字から拡大数字，バーグラフ，アイコン，色表示へと変更することが望ましい。そして、運転負荷が増大して所定値を越えたときには、車両運転の妨げとならないようにすべく、その表示輝度を低下させる表示輝度低下手段を備えることが望ましい。このとき、車両情報の表示形式が頻繁に変更されることで、車両運転者に違和感などを感じさせないようにすべく、所定時間間隔で運転負荷を判定するとよい。 For this reason, in the vehicle information display device according to the present invention, the display means for displaying the vehicle information, the driving load determination means for determining the driving load of the vehicle driver, and the display format of the vehicle information according to the driving load are sequentially changed. And display format changing means.
Here, it is desirable to change the display format of the vehicle information from a standard number to an enlarged number, a bar graph, an icon, and a color display in order to sequentially change the display format to be easily recognized by humans. When the driving load increases and exceeds a predetermined value, it is desirable to provide display luminance lowering means for reducing the display luminance so as not to hinder vehicle driving. At this time, it is preferable to determine the driving load at predetermined time intervals so as not to make the vehicle driver feel uncomfortable by frequently changing the display format of the vehicle information.

また、運転負荷判定手段は、車両運転者の運転負荷と密接に関連する車速又は操舵角に応じて、運転負荷を判定すればよい。   Further, the driving load determination means may determine the driving load according to the vehicle speed or the steering angle that is closely related to the driving load of the vehicle driver.

本発明に係る車両情報表示装置によれば、車両運転者の運転負荷に応じて、車両情報の表示形式が順次変更される。このため、車両情報の表示形式を、人間にとって認識し易いものに適宜変更するようにすれば、車両運転を妨げないようにしつつ、車両運転者の認識度を向上させることができる。また、車速の高低にかかわらず車両情報が表示されるため、例えば、高速道路走行中に走行可能距離を必要以上に注視することなく確認することが可能となり、車両運転の実情に適合したものとすることができる。   According to the vehicle information display device according to the present invention, the display format of the vehicle information is sequentially changed according to the driving load of the vehicle driver. For this reason, if the display format of the vehicle information is appropriately changed to one that can be easily recognized by humans, the degree of recognition of the vehicle driver can be improved while not disturbing the vehicle driving. In addition, since vehicle information is displayed regardless of the vehicle speed, it is possible to check the driving distance without paying more attention than necessary while driving on a highway. can do.

以下、添付された図面を参照して本発明を詳述する。
図１は、本発明に係る車両情報表示装置を備えたコンビネーションメータを示す。
コンビネーションメータ１０には、少なくとも、車速を表示する車速計１２と、燃料残量を表示する燃料計１４と、各種異常を報知する複数の警告灯１６と、車両情報を表示する表示手段としての表示装置１８と、が夫々備えられる。表示装置１８は、図２に示すように、液晶（ＬＣＤ；Liquid Crystal Display）１８Ａと、その背面に配設されるバックライト１８Ｂと、を含んで構成される。ここで、バックライト１８Ｂとしては、車両情報の表示色又は背景色を変化させるべく、複数の色を任意に切換可能なものとすることが望ましい。 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows a combination meter equipped with a vehicle information display device according to the present invention.
The combination meter 10 includes at least a vehicle speed meter 12 for displaying the vehicle speed, a fuel meter 14 for displaying the remaining amount of fuel, a plurality of warning lights 16 for notifying various abnormalities, and a display as display means for displaying vehicle information. A device 18 is provided. As shown in FIG. 2, the display device 18 includes a liquid crystal display (LCD) 18A and a backlight 18B disposed on the back surface thereof. Here, as the backlight 18B, it is desirable that a plurality of colors can be arbitrarily switched in order to change the display color or background color of the vehicle information.

また、車両情報表示装置には、ＬＣＤ１８Ａを駆動するＬＣＤドライバ２０と、バックライト１８Ｂの輝度及び色を変化させるバックライトインタフェース（Ｉ／Ｆ）２２と、コンピュータを内蔵した制御装置２４と、センサとのインタフェースを確保するセンサインタフェース（Ｉ／Ｆ）２６と、が夫々備えられる。そして、車両運転者の運転負荷を判定すべく、例えば、アクスルシャフトの回転速度を介して車速Ｓを検出する車速センサ２８（車速検出手段）からの信号が制御装置２４に入力され、そのＲＯＭ（Read Only Memory）に記憶された制御プログラムにより、ＬＣＤドライバ２０及びバックライトＩ／Ｆ２２を介して、表示装置１８における車両情報の表示形式が順次変更される。   The vehicle information display device also includes an LCD driver 20 that drives the LCD 18A, a backlight interface (I / F) 22 that changes the luminance and color of the backlight 18B, a control device 24 incorporating a computer, a sensor, And a sensor interface (I / F) 26 for securing the interface. Then, in order to determine the driving load of the vehicle driver, for example, a signal from a vehicle speed sensor 28 (vehicle speed detection means) that detects the vehicle speed S via the rotational speed of the axle shaft is input to the control device 24 and the ROM ( The display format of the vehicle information on the display device 18 is sequentially changed via the LCD driver 20 and the backlight I / F 22 by the control program stored in the Read Only Memory).

図３は、イグニッションスイッチのＯＮを契機として、制御装置２４において実行される制御プログラムの処理内容を示す。なお、制御装置２４の制御プログラムを実行することで、運転負荷判定手段，表示形式変更手段及び表示輝度低下手段が夫々実現される。
ステップ１（図では「Ｓ１」と略記する。以下同様）では、各種初期化を行う。即ち、車両情報を初期表示すべく、図１に示すような標準数字で車両情報を表示すると共に、その表示形式を変更するためのパラメータとして、ＲＯＭなどから閾値Ａ〜Ｄ（Ａ＜Ｂ＜Ｃ＜Ｄ）及び制御時間間隔を夫々読み込む。ここで、閾値Ａ〜Ｄには、例えば、車両が極低速，低速，中速，高速又は極高速で走行中であるか否かを判定するための車速閾値が設定される。また、閾値Ａ〜Ｄ及び制御時間間隔をＲＯＭなどから読み込むようにすることで、制御プログラムを変更せず、制御内容を簡単に変更することができる。 FIG. 3 shows the processing contents of the control program executed in the control device 24 when the ignition switch is turned on. In addition, by executing the control program of the control device 24, an operating load determination unit, a display format change unit, and a display luminance reduction unit are realized.
In step 1 (abbreviated as “S1” in the figure, the same applies hereinafter), various initializations are performed. That is, in order to initially display the vehicle information, the vehicle information is displayed with standard numbers as shown in FIG. 1, and the thresholds A to D (A <B <C) are read from the ROM or the like as parameters for changing the display format. <D) and control time interval are read respectively. Here, as the thresholds A to D, for example, a vehicle speed threshold for determining whether or not the vehicle is traveling at a very low speed, a low speed, a medium speed, a high speed, or a very high speed is set. Further, by reading the thresholds A to D and the control time interval from the ROM or the like, the control contents can be easily changed without changing the control program.

ステップ２では、前回の処理が行われてから所定時間経過したか否か、即ち、制御時間間隔となったか否かを判定する。そして、所定時間経過したならばステップ３へと進む一方（Ｙｅｓ）、所定時間経過していなければ待機する（Ｎｏ）。
ステップ３では、車速センサ２８から車速Ｓを読み込む。
ステップ４では、車速が０か否か、即ち、停車中であるか否かを判定する。そして、車速Ｓが０であればステップ５へと進み（Ｙｅｓ）、図４（Ａ）に示すように、車両情報の表示形式を標準数字に変更した後、ステップ２へと戻る。一方、車速Ｓが０でなければステップ６へと進む（Ｎｏ）。 In step 2, it is determined whether or not a predetermined time has elapsed since the previous processing was performed, that is, whether or not a control time interval has been reached. If the predetermined time has elapsed, the process proceeds to step 3 (Yes), while if the predetermined time has not elapsed, the process waits (No).
In step 3, the vehicle speed S is read from the vehicle speed sensor 28.
In step 4, it is determined whether or not the vehicle speed is 0, that is, whether or not the vehicle is stopped. And if the vehicle speed S is 0, it will progress to step 5 (Yes), and as shown to FIG. 4 (A), after changing the display format of vehicle information to a standard number, it will return to step 2. On the other hand, if the vehicle speed S is not 0, the routine proceeds to step 6 (No).

ステップ６では、車速Ｓが閾値Ａ以下であるか否か、即ち、車両が極低速で走行中であるか否かを判定する。そして、車速Ｓが閾値Ａ以下であればステップ７へと進み（Ｙｅｓ）、図４（Ｂ）に示すように、車両情報の表示形式を拡大数字に変更した後、ステップ２へと戻る。ここで、「拡大数字」とは、標準数字よりもポイント（大きさ）が大きい数字のことをいう。一方、車速Ｓが閾値Ａより大であればステップ８へと進む（Ｎｏ）。   In step 6, it is determined whether or not the vehicle speed S is equal to or lower than the threshold A, that is, whether or not the vehicle is traveling at an extremely low speed. If the vehicle speed S is less than or equal to the threshold value A, the process proceeds to step 7 (Yes), and the vehicle information display format is changed to an enlarged number as shown in FIG. Here, the “enlarged number” means a number having a point (size) larger than the standard number. On the other hand, if the vehicle speed S is greater than the threshold A, the process proceeds to step 8 (No).

ステップ８では、車速Ｓが閾値Ｂ以下であるか否か、即ち、車速が低速で走行中であるか否かを判定する。そして、車速Ｓが閾値Ｂ以下であればステップ９へと進み（Ｙｅｓ）、図４（Ｃ）に示すように、車両情報の表示形式をバーグラフに変更した後、ステップ２へと戻る。一方、車速Ｓが閾値Ｂより大であればステップ１０へと進む（Ｎｏ）。
ステップ１０では、車速Ｓが閾値Ｃ以下であるか否か、即ち、車両が中速で走行中であるか否かを判定する。そして、車速Ｓが閾値Ｃ以下であればステップ１１へと進み（Ｙｅｓ）、図４（Ｄ）又は（Ｅ）に示すように、車両情報の表示形式をアイコンに変更した後、ステップ２へと戻る。一方、車速Ｓが閾値Ｃより大であればステップ１２へと進む（Ｎｏ）。 In step 8, it is determined whether or not the vehicle speed S is equal to or lower than the threshold value B, that is, whether or not the vehicle is traveling at a low speed. If the vehicle speed S is less than or equal to the threshold B, the process proceeds to step 9 (Yes), and the vehicle information display format is changed to a bar graph as shown in FIG. On the other hand, if the vehicle speed S is greater than the threshold B, the process proceeds to step 10 (No).
In step 10, it is determined whether or not the vehicle speed S is less than or equal to the threshold value C, that is, whether or not the vehicle is traveling at a medium speed. If the vehicle speed S is equal to or lower than the threshold value C, the process proceeds to step 11 (Yes), and the vehicle information display format is changed to an icon as shown in FIG. Return. On the other hand, if the vehicle speed S is greater than the threshold value C, the routine proceeds to step 12 (No).

ステップ１２では、車速Ｓが閾値Ｄ以下であるか否か、即ち、車両が高速で走行中であるか否かを判定する。そして、車速Ｓが閾値Ｄ以下であればステップ１３へと進み（Ｙｅｓ）、図４（Ｆ）に示すように、車両情報の表示形式を色表示に変更すべく、バックライト１８Ｂの色を切り換えた後、ステップ２へと戻る。一方、車速Ｓが閾値Ｄより大、即ち、車両が極高速で走行中であればステップ１４へと進み（Ｎｏ）、図４（Ｇ）に示すように、車両情報の表示輝度を低下させるべく、バックライト１８Ｂの輝度を低下させた後、ステップ２へと戻る。   In step 12, it is determined whether or not the vehicle speed S is less than or equal to the threshold value D, that is, whether or not the vehicle is traveling at a high speed. If the vehicle speed S is less than or equal to the threshold value D, the process proceeds to step 13 (Yes), and the color of the backlight 18B is switched to change the vehicle information display format to color display as shown in FIG. After that, return to Step 2. On the other hand, if the vehicle speed S is greater than the threshold value D, that is, if the vehicle is traveling at an extremely high speed, the routine proceeds to step 14 (No), and as shown in FIG. After the brightness of the backlight 18B is lowered, the process returns to step 2.

かかる車両情報表示装置によれば、車両情報の表示形式は、車速の上昇に伴って、図４（Ａ）〜（Ｆ）に示すように、標準数字から拡大数字，バーグラフ，アイコン，色表示へと順次変更される。このため、車両情報は、車速の上昇に伴って、簡略化された表示形式で順次表示されるため、車速の高低にかかわらず容易に認識可能となり、車両運転を妨げないようにしつつ、車両運転者の認識度を向上させることができる。また、車速の高低にかかわらず車両情報が表示されるため、例えば、高速道路走行中に走行可能距離を必要以上に注視することなく確認することが可能となり、車両運転の実情に適合したものとすることができる。   According to such a vehicle information display device, the display format of the vehicle information is displayed from standard numbers to enlarged numbers, bar graphs, icons, and colors as shown in FIGS. 4A to 4F as the vehicle speed increases. Will be changed sequentially. For this reason, the vehicle information is sequentially displayed in a simplified display format as the vehicle speed increases, so that it can be easily recognized regardless of the vehicle speed, and the vehicle operation is not disturbed. Person's recognition level can be improved. In addition, since vehicle information is displayed regardless of the vehicle speed, it is possible to check the driving distance without paying more attention than necessary while driving on a highway. can do.

さらに、車速Ｓが閾値Ｄを越えたときには、運転者に見えなくなるように車両情報の表示輝度を低下させることによって、車両運転者が車両情報に注意を払うことが抑制され、車両運転に集中することができる。
なお、車速Ｓに代えて、操舵角を検出する操舵角センサ（操舵角検出手段）からの出力を用い、車両運転者の運転負荷を判定するようにしてもよい。また、ＬＣＤ単体で、車両情報の表示色又は背景色並びに表示輝度を変化させることができるときには、バックライトを制御せずに、ＬＣＤを直接制御するようにしてもよい。 Further, when the vehicle speed S exceeds the threshold D, the display brightness of the vehicle information is reduced so that the vehicle information is not visible to the driver, thereby suppressing the vehicle driver from paying attention to the vehicle information and concentrating on driving the vehicle. be able to.
Instead of the vehicle speed S, the driving load of the vehicle driver may be determined using an output from a steering angle sensor (steering angle detecting means) that detects the steering angle. Further, when the display color or background color of vehicle information and the display brightness can be changed by a single LCD, the LCD may be directly controlled without controlling the backlight.
