　車両情報表示装置１は、制御コントローラ２、車両診断アダプタ３、表示ユニット４を備える。
　ここで車両診断アダプタ３は、車両１０に設けられた車両診断等に利用する車両診断コネクタ１０Ｂに接続され、制御コントローラ２の制御により、車両診断コネクタ１０Ｂを介して車両１０に設けられたコントローラ（車両ＥＣＵ）に車両情報の送出をリクエストし、またこのリクエストに対する応答により車両１０から車両情報を取得して制御コントローラ２に出力する。 The vehicle information display device 1 includes a controller 2, a vehicle diagnostic adapter 3, and a display unit 4.

　表示部６は、画像表示領域６Ａが分割されて、それぞれ車両情報を表示する小領域が形成され、各小領域でそれぞれドライバーにより選択された車両情報を表示する。 FIG. 2 is a plan view showing a display example of vehicle information on the display unit 6.
In the vehicle information display device 1, selection of vehicle information to be displayed is accepted in advance by the driver's operation detected via the input unit 7 and displayed on the display unit 6.
In the display unit 6, the image display area 6A is divided into small areas for displaying vehicle information, and the vehicle information selected by the driver is displayed in each small area.
　この図２の例では、画像表示領域６Ａに６つの小領域が形成され、現在時刻（「ＣＬＯＣＫ」、「１０：２４」）、車速（「ＳＰＥＥＤ」、「１０３ｋｍ/ｈ」）、油温（「ＯＩＬ　Ｔ.」、「９６℃」）、水温（「ＷＡＴＥＲ　Ｔ.」、「８６℃」）、油圧（「ＯＩＬ　Ｐ.」、「４．５×１００ｋｐａ」）、エンジン排気ガス温度（「ＥＸＴ.Ｔ.」、「３７８℃」）が表示されている。 In the example of FIG. 2, six small areas are formed in the image display area 6A, and the current time (“CLOCK”, “10:24”), vehicle speed (“SPEED”, “103 km/h”), oil temperature ( "OIL T.", "96°C"), water temperature ("WATER T.", "86°C"), hydraulic pressure ("OIL P.", "4.5 x 100 kpa"), engine exhaust gas temperature ("EXT .T." and "378°C") are displayed.
　制御コントローラ２（図１）は、車両情報取得部８、制御部９を備える。
　制御コントローラ２は、演算処理回路を備え、この演算処理回路によりこの車両情報表示装置１の制御プログラムを実行することにより、所定の処理手順を実行して車両情報取得部８、制御部９が構成される。 The controller 2 (FIG. 1) includes a vehicle information acquisition unit 8 and a control unit 9.
The controller 2 includes an arithmetic processing circuit, and the arithmetic processing circuit executes a control program of the vehicle information display device 1 to execute a predetermined processing procedure to configure the vehicle information acquisition unit 8 and the control unit 9. To be done.
　ここで車両情報取得部８は、表示に供する車両情報を取得する構成であり、制御部９の制御により、センサ群１０Ａに係る各センサを駆動して、各センサによる検出結果をサンプリングすることにより車両情報を取得し、取得した車両情報を制御部９に出力する。また制御部９の制御により、車両診断アダプタ３により車両情報のリクエストを送出し、またこのリクエストの応答による車両情報を車両診断アダプタ３により取得する。これにより車両情報取得部８は、車両１０に設けられた車両診断コネクタ１０Ｂとのデータ通信により車両情報を取得し、取得した車両情報を制御部９に出力する。 Here, the vehicle information acquisition unit 8 is configured to acquire the vehicle information to be displayed, and by controlling the control unit 9 drives each sensor related to the sensor group 10A and samples the detection result by each sensor. The vehicle information is acquired, and the acquired vehicle information is output to the control unit 9. Further, under the control of the control unit 9, the vehicle diagnostic adapter 3 sends a vehicle information request, and the vehicle diagnostic adapter 3 acquires vehicle information in response to the request. As a result, the vehicle information acquisition unit 8 acquires the vehicle information through data communication with the vehicle diagnostic connector 10B provided on the vehicle 10, and outputs the acquired vehicle information to the control unit 9.
　制御部９は、車両情報取得部８、表示部６を制御する。
　すなわち制御部９は、電源の供給開始により、車両情報取得部８により事前にドライバーにより選択された車両情報を取得し、またこの車両情報を表示部６により表示する。またこのようにして車両情報を表示して、車両情報を警告設定値により判定し、車両情報が警告設定値を超えて上昇すると、表示部６の表示によりドライバーに警告を通知する。 The control unit 9 controls the vehicle information acquisition unit 8 and the display unit 6.
That is, the control unit 9 acquires the vehicle information previously selected by the driver by the vehicle information acquisition unit 8 when the power supply is started, and displays the vehicle information on the display unit 6. In addition, the vehicle information is displayed in this manner, the vehicle information is determined based on the warning set value, and when the vehicle information rises above the warning set value, the display unit 6 displays a warning to the driver.
　このように車両情報に係る一連の処理を実行するようにして、制御部９は、入力部７により検出されるドライバーの操作により、表示部６の表示をメニュー画面の表示に切替え、このメニュー画面におけるドライバーの操作に応動して表示部６で表示する車両情報の選択を受け付ける。これにより制御部９は、このようにして選択された車両情報に応じてセンサ群１０Ａ、車両診断アダプタ３より対応する車両情報を取得して表示部６で表示する。 In this way, the control unit 9 switches the display of the display unit 6 to the display of the menu screen by the driver's operation detected by the input unit 7 by executing the series of processes related to the vehicle information. The selection of the vehicle information to be displayed on the display unit 6 is accepted in response to the driver's operation in. As a result, the control unit 9 acquires the corresponding vehicle information from the sensor group 10A and the vehicle diagnostic adapter 3 according to the vehicle information selected in this way, and displays it on the display unit 6.
　また同様にして、警告を通知する車両情報の選択、対応する警告設定値の設定を受け付ける。 ∙ Similarly, the selection of vehicle information to notify the warning and the setting of the corresponding warning set value are accepted.
　〔車両情報取得周期の制御〕
　ところでこのようにして表示する車両情報は、例えばエンジン吸気圧力のように、値が常に大きく変動するものがあり、このような車両情報は、短い時間周期により取得して表示することが望まれる。
　また車両速度、エンジン回転数、エンジン潤滑油圧力、エンジン冷却水温度、エンジン潤滑油温度、エンジン排気ガス温度、車両補器電圧等にあっては、変動が比較的緩やかであり、通常は値が殆ど変化しない。これにより消費電力を低減し、さらには限られたリソースを有効に利用する観点から、長い時間周期により取得して表示することが好ましい。
　しかしながらこのような長い時間周期により取得することが好ましい車両情報にあっても、異常が発生した場合等にあっては、値が大きく変動する場合がある。
　これにより制御部９は、車両情報の取得周期を適宜、切り替え、消費電力の増大を有効に回避しつつ、限られたリソースを有効に利用して車両情報を表示するようにして、必要に応じて詳細に車両情報を表示する。 [Control of vehicle information acquisition cycle]
By the way, the value of the vehicle information displayed in this way is such that the value always fluctuates greatly like the engine intake pressure, and it is desirable to acquire and display such vehicle information in a short time period.
In addition, the vehicle speed, engine speed, engine lubricating oil pressure, engine cooling water temperature, engine lubricating oil temperature, engine exhaust gas temperature, vehicle auxiliary device voltage, etc., have relatively slow fluctuations, and normally the values are It hardly changes. Therefore, from the viewpoint of reducing power consumption and effectively using limited resources, it is preferable to acquire and display the data in a long time period.
However, even if there is vehicle information that is preferably acquired in such a long time period, the value may fluctuate significantly when an abnormality occurs.
As a result, the control unit 9 appropriately switches the vehicle information acquisition cycle, effectively avoids an increase in power consumption, and effectively uses limited resources to display the vehicle information, if necessary. To display vehicle information in detail.
　また車両情報が警告設定値に近づいた場合は、このような詳細な車両情報が必要な場合であることにより、この実施形態では、ドライバーにより設定された警告設定値を基準にして取得周期切替判定基準値を設定し、この取得周期切替判定基準値により対応する車両情報の取得周期を切り替える。
　なおこのようにして特定の車両情報が警告設定値に近づいた場合には、警告設定値を設定していない他の車両情報についても、詳細な車両情報の通知が好ましい場合もある。具体的に、例えば走行中に車両が故障したような場合、瞬間的に油圧が低下したり、水温が急激に上昇する等の車両情報の急激な変化が発生する。
　これにより特定の車両情報が警告設定値に近づいた場合に、他の車両情報についても、車両情報の取得周期を切り替えるようにしてもよい。 Further, when the vehicle information approaches the warning set value, such detailed vehicle information is necessary. Therefore, in this embodiment, the acquisition cycle switching determination is performed based on the warning set value set by the driver. A reference value is set, and the acquisition cycle of the corresponding vehicle information is switched according to this acquisition cycle switching determination reference value.
When the specific vehicle information approaches the warning set value in this way, detailed vehicle information notification may be preferable for other vehicle information for which the warning set value is not set. Specifically, for example, when a vehicle breaks down during traveling, a sudden change in vehicle information occurs such as a momentary decrease in hydraulic pressure or a sharp rise in water temperature.
Thus, when the specific vehicle information approaches the warning set value, the acquisition cycle of the vehicle information may be switched for other vehicle information.
　図３は、車両情報の取得周期を切り替えないとした場合に考えられる制御部９の処理手順の説明に供するフローチャートである。なおこの図３の処理は、エンジン吸気圧力、車両速度、エンジン回転数、エンジン潤滑油圧力、エンジン冷却水温度、車両補器電圧の表示がドライバーにより指示された場合であり、これらの車両情報をセンサ群１０Ａにより取得する場合の例である。 FIG. 3 is a flowchart for explaining a processing procedure of the control unit 9 that can be considered when the acquisition cycle of vehicle information is not switched. The process of FIG. 3 is performed when the driver instructs the display of the engine intake pressure, the vehicle speed, the engine speed, the engine lubricating oil pressure, the engine cooling water temperature, and the vehicle auxiliary device voltage. This is an example of the case of acquisition by the sensor group 10A.
　この場合、制御部９は、エンジン吸気圧力については、車両情報取得部８による車両情報のサンプリング周期を短い時間間隔に設定し（ＳＰ２）、車両速度、エンジン回転数、エンジン潤滑油圧力、エンジン冷却水温度、車両補器電圧については、車両情報取得部８による車両情報のサンプリング周期を長い時間間隔に設定し（ＳＰ３、ＳＰ４、ＳＰ５、ＳＰ６、ＳＰ７）、この設定により車両情報を取得して表示することになる。 In this case, for the engine intake pressure, the control unit 9 sets the sampling period of the vehicle information by the vehicle information acquisition unit 8 to a short time interval (SP2), vehicle speed, engine speed, engine lubricating oil pressure, engine cooling. Regarding the water temperature and the vehicle accessory voltage, the vehicle information acquisition unit 8 sets the vehicle information sampling cycle to a long time interval (SP3, SP4, SP5, SP6, SP7), and acquires and displays the vehicle information by this setting. Will be done.
　これに対して図４は、図３との対比により、車両情報の取得周期の切り替えに係る制御部９の処理手順を示すフローチャートである。
　ここで制御部９は、例えば警告設定値の９０％の値を取得周期切替判定基準値に設定し、一定の時間間隔によりこの図４の処理手順を実行する。なお取得周期切替判定基準値は、車両情報に応じて種々に設定することができ、さらにはドライバーによる設定を受け付けるようにしてもよい。 On the other hand, FIG. 4 is a flowchart showing the processing procedure of the control unit 9 relating to the switching of the vehicle information acquisition cycle, in comparison with FIG.
Here, the control unit 9 sets, for example, a value of 90% of the warning set value as the acquisition cycle switching determination reference value, and executes the processing procedure of FIG. 4 at regular time intervals. The acquisition cycle switching determination reference value can be set variously according to the vehicle information, and may be set by the driver.
　この場合、制御部９は、対応する車両情報を取得周期切替判定基準値により判定することにより、車両情報が取得周期切替判定基準値を超えたか否か判断し、これにより車両情報が警告設定値に近づいたか否か判断する（ＳＰ１１）。
　また車両情報が取得周期切替判定基準値を超えていない場合、図３について上述したと同様の処理により、サンプリング周期を設定する（ＳＰ２、ＳＰ３、ＳＰ４、ＳＰ５、ＳＰ６、ＳＰ７）。 In this case, the control unit 9 determines whether or not the vehicle information exceeds the acquisition cycle switching determination reference value by determining the corresponding vehicle information by the acquisition cycle switching determination reference value. It is determined whether or not (SP11).
If the vehicle information does not exceed the acquisition cycle switching determination reference value, the sampling cycle is set by the same processing as described above with reference to FIG. 3 (SP2, SP3, SP4, SP5, SP6, SP7).
　これに対して車両情報が取得周期切替判定基準値を超えた場合、この車両情報が例えば車両速度、エンジン回転数、エンジン潤滑油圧力、エンジン冷却水温度、車両補器電圧の車両情報である場合、この取得周期切替判定基準値を超えた車両情報のサンプリング周期を短い時間間隔に設定する（ＳＰ１３、ＳＰ１４、ＳＰ１５、ＳＰ１６、ＳＰ１７）。なおエンジン吸気圧については、当初、サンプリング周期が短い時間間隔に設定されていることにより、取得周期切替判定基準値を超えても、サンプリング周期は短い時間間隔に設定されたままに保持される（ＳＰ１２）。 On the other hand, when the vehicle information exceeds the acquisition cycle switching determination reference value, when the vehicle information is vehicle information such as vehicle speed, engine speed, engine lubricating oil pressure, engine cooling water temperature, and vehicle auxiliary voltage The sampling cycle of vehicle information that exceeds the acquisition cycle switching determination reference value is set to a short time interval (SP13, SP14, SP15, SP16, SP17). Regarding the engine intake pressure, since the sampling period is initially set to a short time interval, even if the acquisition period switching determination reference value is exceeded, the sampling period is kept set to the short time interval ( SP12).
　図５は、この図４の処理による車両情報の処理の説明に供するタイムチャートである。この場合、制御部９における図４の処理手順の繰り返しにより、車両情報が変化して警告設定値に近づくと（図５（Ａ）及び（Ｂ））、対応する車両情報のサンプリング周期が短くなり（図５（Ｃ））、これにより詳細な車両情報の提供が開始される。またこの車両情報が警告設定値より遠ざかると、車両情報のサンプリング周期が長くなり、これにより消費電力の低減が図られ、さらにはリソースの負担が軽減される。 FIG. 5 is a time chart used to explain the processing of vehicle information by the processing of FIG. In this case, when the vehicle information changes and approaches the warning set value by repeating the processing procedure of FIG. 4 in the control unit 9 (FIGS. 5A and 5B), the sampling cycle of the corresponding vehicle information becomes short. (FIG. 5(C)), whereby provision of detailed vehicle information is started. Further, when the vehicle information moves away from the warning set value, the vehicle information sampling cycle becomes longer, which reduces power consumption and resource load.
　なお車両情報にあっては、バックグランドにおける監視により警告設定値を超えると例えばポップアップ等により警告が通知される場合も考えられ、これにより表示中の車両情報以外の車両情報についても、取得周期切替判定基準値による判定によりサンプリング周期を切り替えるようにしてもよい。
　また警告設定値にあっては、ドライバーによる設定に加えて、又はドライバーによる設定に代えて、通常の車両で警告表示に供する基準値を適用するようにしてもよい。
　また取得周期切替判定基準値にあっては、警告設定値を基準にした設定に代えて、又は警告設定値を基準にした設定に加えて、ドライバーにより設定を受け付けるようにしてもよく、必要に応じて種々に設定することができる。 In the case of vehicle information, if the warning setting value is exceeded by monitoring in the background, a warning may be given by, for example, a pop-up, so that the acquisition cycle can be switched for vehicle information other than the displayed vehicle information. The sampling cycle may be switched according to the determination based on the determination reference value.
Further, as the warning set value, in addition to the setting by the driver or instead of the setting by the driver, a reference value provided for warning display in a normal vehicle may be applied.
In addition, in the acquisition cycle switching determination reference value, the driver may accept the setting instead of the setting based on the warning setting value or in addition to the setting based on the warning setting value. Various settings can be made according to the setting.
　図６は、図３との対比により、車両診断アダプタ３を介して車両１０から取得する車両情報について、車両情報の取得周期を切り替えないとした場合に考えられる、車両情報の取得周期の設定に係る処理手順を示すフローチャートである。
　この場合、制御部９は、当初設定した標準設定値によるリクエスト周期により車両１０に車両情報をリクエストして取得する（ＳＰ２２）。 FIG. 6 shows the setting of the vehicle information acquisition cycle that can be considered when the vehicle information acquisition cycle is not switched for the vehicle information acquired from the vehicle 10 via the vehicle diagnostic adapter 3 by comparison with FIG. It is a flow chart which shows the processing procedure concerned.
In this case, the control unit 9 requests and acquires the vehicle information from the vehicle 10 at the request cycle based on the initially set standard setting value (SP22).
　これに対して図７は、図６との対比により、この車両診断アダプタ３を介して車両１０から取得する車両情報の取得周期を切り替える場合の処理手順の説明に供するフローチャートである。
　この場合、制御部９は、対応する車両情報を取得周期切替判定基準値により判定し（ＳＰ３１）、車両情報が取得周期切替判定基準値を超えていない場合、図６について上述した標準設定値によるリクエスト周期により車両１０に車両情報をリクエストして取得する（ＳＰ２２）。また車両情報が取得周期切替判定基準値を超えた場合、この取得周期切替判定基準値を超えた車両情報については、標準設定値より短いリクエスト周期により車両１０に車両情報をリクエストして取得する（ＳＰ３２）。 On the other hand, FIG. 7 is a flowchart for explaining the processing procedure when the acquisition cycle of the vehicle information acquired from the vehicle 10 via the vehicle diagnosis adapter 3 is switched by comparison with FIG. 6.
In this case, the control unit 9 determines the corresponding vehicle information by the acquisition cycle switching determination reference value (SP31), and when the vehicle information does not exceed the acquisition cycle switching determination reference value, by the standard setting value described above with reference to FIG. The vehicle information is requested and acquired from the vehicle 10 at the request cycle (SP22). When the vehicle information exceeds the acquisition cycle switching determination reference value, the vehicle information that exceeds the acquisition cycle switching determination reference value is acquired by requesting the vehicle information to the vehicle 10 at a request cycle shorter than the standard setting value ( SP32).
　図８は、この図７の処理による車両情報の処理の説明に供するタイムチャートである。この場合、制御部９における図７の処理手順の繰り返しにより、車両情報が変化して警告設定値に近づくと（図８（Ａ）及び（Ｂ））、対応する車両情報のリクエスト周期が短くなり（図８（Ｃ））、これにより詳細な車両情報の提供が開始される。また車両情報が警告設定値より遠ざかると、車両情報のリクエスト周期が長くなり、これにより消費電力の低減が図られ、さらに車両情報表示装置１及び車両１０側の車両情報の処理に係るリソースの負担が軽減される。 FIG. 8 is a time chart used to explain the processing of vehicle information by the processing of FIG. In this case, when the vehicle information changes and approaches the warning set value by repeating the processing procedure of FIG. 7 in the control unit 9 (FIGS. 8A and 8B), the request cycle of the corresponding vehicle information becomes short. (FIG. 8(C)), whereby provision of detailed vehicle information is started. Further, when the vehicle information becomes farther from the warning set value, the vehicle information request period becomes longer, which reduces power consumption, and further burdens resources related to vehicle information processing on the vehicle information display device 1 and the vehicle 10. Is reduced.
　〔表示更新周期の制御〕
　ところでこのようにしてサンプリング周期、リクエスト周期を短くして詳細な車両情報を通知する場合あっても、表示部６に係る表示内容の更新周期が不十分な場合には、詳細に車両情報を通知できなくなる。
　因みに、サンプリング周期、リクエスト周期を短くしても充分な程度に、表示部６に係る表示内容の更新周期を短く設定しておくことも考えられるものの、この場合、消費電力が増大し、さらにはリソースを充分に確保しておくことが必要になる。
　そこでこの実施形態では、車両情報の取得周期の短縮に対応するように、表示部６における表示内容の更新周期を短縮する。 [Control of display update cycle]
By the way, even if the detailed cycle information is notified by shortening the sampling cycle and the request cycle in this way, the detailed vehicle information is notified when the update cycle of the display content of the display unit 6 is insufficient. become unable.
Incidentally, although it is conceivable to set the update period of the display content of the display unit 6 to be short enough to shorten the sampling period and the request period, in this case, the power consumption increases, and further, It is necessary to secure sufficient resources.
Therefore, in this embodiment, the update cycle of the display content on the display unit 6 is shortened so as to correspond to the shortening of the vehicle information acquisition cycle.
　ここで図９は、このような更新周期を切り替えないとした場合に考えられる、更新周期の設定に係る処理手順を示すフローチャートである。 Here, FIG. 9 is a flowchart showing a processing procedure relating to the setting of the update cycle, which can be considered when such an update cycle is not switched.
　この場合、制御部９は、表示内容の更新周期を標準設定値に設定し（ＳＰ４２）、この標準設定値により表示部６に設けられた画像メモリを更新し、これによりこの画像メモリから一定速度で読み出されて表示部６で表示される表示内容を更新し、表示部６における表示内容の更新速度を標準設定値に設定する。 In this case, the control unit 9 sets the update cycle of the display content to the standard setting value (SP42), updates the image memory provided in the display unit 6 with this standard setting value, and the constant speed is changed from this image memory. The display content read out in step S4 and displayed on the display unit 6 is updated, and the update speed of the display content on the display unit 6 is set to a standard setting value.
　これに対して図１０は、図９との対比により、更新周期の切り替えに係る制御部９の処理手順を示すフローチャートである。
　ここで制御部９は、取得周期切替判定基準値と同一値を更新周期切替判定基準値に設定し、この更新周期切替判定基準値と車両情報との比較により車両情報が警告設定値に近づいたか否か判断して更新周期を切り替える（ＳＰ５１－ＳＰ５２）。
　なおサンプリング周期、リクエスト周期との対比により、取得周期切替判定基準値に比して警告設定値に近い側の値を更新周期切替判定基準値に設定してもよく、これとは逆に、取得周期切替判定基準値に比して警告設定値から遠い側の値を更新周期切替判定基準値に設定してもよい。 On the other hand, FIG. 10 is a flowchart showing a processing procedure of the control unit 9 relating to switching of the update cycle, in comparison with FIG. 9.
Here, the control unit 9 sets the same value as the acquisition cycle switching determination reference value to the update cycle switching determination reference value, and whether the vehicle information approaches the warning setting value by comparing the update cycle switching determination reference value with the vehicle information. It is determined whether or not the update cycle is switched (SP51-SP52).
Depending on the comparison between the sampling cycle and the request cycle, the value closer to the warning set value than the acquisition cycle switching determination reference value may be set as the update cycle switching determination reference value. A value farther from the warning set value than the cycle switching determination reference value may be set as the update cycle switching determination reference value.
　図１１は、この図１０の処理による表示内容の更新周期の処理の説明に供するタイムチャートである。この場合、制御部９における図１０の処理手順の繰り返しにより、車両情報が変化して警告設定値に近づくと（図１１（Ａ）及び（Ｂ））、更新周期が短くなり（図１１（Ｃ））、これにより詳細な車両情報の提供が開始される。また車両情報が警告設定値より遠ざかると、更新周期が長くなり、これにより消費電力の低減が図られ、さらにはリソースの負担が軽減される。 FIG. 11 is a time chart used to explain the processing of the display content update cycle by the processing of FIG. In this case, when the vehicle information changes to approach the warning set value by repeating the processing procedure of FIG. 10 in the control unit 9 (FIGS. 11A and 11B), the update cycle becomes shorter (FIG. 11C. )), this will start providing detailed vehicle information. Further, if the vehicle information moves away from the warning set value, the update cycle becomes longer, which reduces power consumption and resource load.
　〔車両情報の平均化処理の制御〕
　また、車両情報表示装置１を駆動させるための制御部９は、センサ群１０Ａ及び／又は車両診断コネクタ１０Ｂから取得した車両情報に種々の原因でバラツキが生じるため、前記車両情報を所定の平均化回数（データ数）で平均化処理した結果に基づいて表示部６を表示動作させる。
　そこでこの実施形態では、ドライバーにより設定された警告設定値を基準にして平均化処理基準値を設定し、この平均化処理基準値に対応するように平均化処理の平均化回数を設定する。 [Control of averaging process of vehicle information]
Further, the control unit 9 for driving the vehicle information display device 1 varies the vehicle information acquired from the sensor group 10A and/or the vehicle diagnosis connector 10B due to various causes, and thus the vehicle information is averaged to a predetermined value. The display unit 6 is operated to display based on the result of the averaging process by the number of times (the number of data).
Therefore, in this embodiment, the averaging process reference value is set on the basis of the warning set value set by the driver, and the averaging count of the averaging process is set so as to correspond to the averaging process reference value.
　ここで図１２は、このような車両情報の平均化処理を切り替えないとした場合に考えられる、車両情報の平均化処理に係る処理手順を示すフローチャートである。 Here, FIG. 12 is a flowchart showing a processing procedure relating to the averaging processing of vehicle information, which can be considered when such averaging processing of vehicle information is not switched.
　この場合、制御部９は、平均化処理の平均化回数ｎ（ｎは、２以上の自然数）を標準設定値に設定し（ＳＰ６２）、この標準設定値により表示部６に設けられた画像メモリを更新し、これによりこの画像メモリから一定速度で読み出されて表示部６で表示される表示内容を更新し、表示部６における表示内容の更新速度を標準設定値に設定する。 In this case, the control unit 9 sets the averaging count n (n is a natural number of 2 or more) of the averaging process to a standard setting value (SP62), and the image memory provided in the display unit 6 is set according to the standard setting value. Is updated, whereby the display content read out from the image memory at a constant speed and displayed on the display unit 6 is updated, and the update speed of the display content on the display unit 6 is set to a standard setting value.
　これに対して図１３は、図１２との対比により、車両情報の平均化処理の切り替えに係る制御部９の処理手順を示すフローチャートである。
　ここで制御部９は、取得周期切替判定基準値と同一値を平均化処理基準値に設定し、この平均化処理基準値と車両情報との比較により車両情報が警告設定値に近づいたか否か判断して平均化処理の平均化回数を切り替える。制御部９は、警告設定値に近づいたと判断した場合に、標準設定値よりも小さいｍ（ｍは、ｎより小さい０を除く自然数）を平均化回数に設定し（ＳＰ７１－ＳＰ７２）、警告設定値に近づいたと判断しない場合には標準設定値であるｎを平均化回数に設定する（ＳＰ７１－ＳＰ６２）。
　なおサンプリング周期、リクエスト周期、表示内容の更新周期との対比により、取得周期切替判定基準値に比して警告設定値に近い側の値を平均化処理基準値に設定してもよく、これとは逆に、取得周期切替判定基準値に比して警告設定値から遠い側の値を平均化処理基準値に設定してもよい。 On the other hand, FIG. 13 is a flowchart showing the processing procedure of the control unit 9 relating to the switching of the averaging processing of the vehicle information, in comparison with FIG.
Here, the control unit 9 sets the same value as the acquisition cycle switching determination reference value as the averaging processing reference value, and compares the averaging processing reference value with the vehicle information to determine whether the vehicle information has approached the warning setting value. Judgment is made and the number of times of averaging processing is switched. When it is determined that the warning setting value is approached, the control unit 9 sets m smaller than the standard setting value (m is a natural number less than 0 and smaller than n) as the averaging count (SP71-SP72), and sets the warning setting. When it is not determined that the value has approached, the standard setting value n is set as the averaging count (SP71-SP62).
Note that, by comparing the sampling cycle, request cycle, and display content update cycle, the value closer to the warning set value than the acquisition cycle switching determination reference value may be set as the averaging process reference value. Conversely, a value farther from the warning set value than the acquisition cycle switching determination reference value may be set as the averaging process reference value.
　図１４は、この図１３の処理による車両情報の平均化処理の説明に供するタイムチャートである。この場合、制御部９における図１３の処理手順の繰り返しにより、車両情報が変化して警告設定値に近づくと（図１４（Ａ）及び（Ｂ））、平均化処理の平均化回数を小さくし（図１４（Ｃ））、これにより詳細な車両情報の提供が開始される。また車両情報が警告設定値より遠ざかると、平均化処理の平均化回数が大きくなり、これにより消費電力の低減が図られ、さらにはリソースの負担が軽減される。 FIG. 14 is a time chart used for explaining the averaging process of vehicle information by the process of FIG. In this case, when the vehicle information changes and approaches the warning set value by repeating the processing procedure of FIG. 13 in the control unit 9 (FIGS. 14A and 14B), the averaging number of the averaging process is reduced. (FIG. 14(C)), whereby the provision of detailed vehicle information is started. Further, when the vehicle information moves away from the warning set value, the number of times of averaging processing is increased, which reduces power consumption and resource load.
　図１５は、この図１３の処理による車両情報の平均化処理の変形例の説明に供するタイムチャートである。この場合、制御部９における図１３の処理手順の繰り返しにより、車両情報が変化して警告設定値に近づくにつれて（図１４（Ａ）及び（Ｂ））、平均化処理の平均化回数を小さくさせ（図１４（Ｃ））、これにより車両情報の急激な変動を回避しつつ、詳細な車両情報の提供が開始される。また車両情報が警告設定値より遠ざかると、平均化処理の平均化回数が大きくなり、これにより消費電力の低減が図られ、さらにはリソースの負担が軽減される。 FIG. 15 is a time chart used for explaining a modified example of the averaging process of vehicle information by the process of FIG. In this case, by repeating the processing procedure of FIG. 13 in the control unit 9, as the vehicle information changes and approaches the warning set value (FIGS. 14A and 14B), the number of times of averaging processing is reduced. (FIG. 14(C)), whereby the provision of detailed vehicle information is started while avoiding abrupt changes in vehicle information. Further, when the vehicle information moves away from the warning set value, the number of times of averaging processing is increased, which reduces power consumption and resource load.
　以上の構成によれば、取得周期切替判定基準値により車両情報を判定して、車両情報の取得周期を切り替えることにより、例えば車両情報の計測値が警告設定値に接近して取得周期切替判定基準値を超えると、車両情報の取得周期を短くして詳細に車両情報を取得することができる。これにより消費電力の増大を有効に回避しつつ、限られたリソースを有効に利用して車両情報を表示するようにして、必要に応じて詳細に車両情報を表示することができる。 According to the above configuration, the vehicle information is determined based on the acquisition cycle switching determination reference value, and the acquisition cycle of the vehicle information is switched. For example, the measured value of the vehicle information approaches the warning setting value When the value exceeds the value, the vehicle information acquisition cycle can be shortened and the vehicle information can be acquired in detail. As a result, while effectively avoiding an increase in power consumption, the vehicle information can be displayed by utilizing the limited resources effectively, and the vehicle information can be displayed in detail as necessary.
