Abstract
Description
Rfは前輪用ローラ、Rrは後輪用ローラで、それぞれに被試験車両の前輪、後輪が乗せられる。前後輪のローラ(Rf、Rr)には図示省略されているが負荷としてのダイナモメータが連結される。IV1,IV2はインバータ盤で、予め設定される設定値と速度検出器Sdによって検出した速度信号等に基づいてインバータ盤を介してダイナモメータが制御される。PLCは開閉器盤で、送風機Blなどの補機電源をオン・オフするための開閉器類のオン・オフ制御を、開閉器盤を介して行う。Opは制御装置部で、この制御装置部(Op)はシーケンサ、コントローラなどの制御部や演算部が収納され、そのための設定及び操作は、制御装置端末部(PC)を介して操作され、制御装置部(Op)と制御装置端末部(PC)などによって操作卓が構成されている。
図6は車種と使用するローラの関係を示したもので、同図の(a)~(f)で示すように前輪駆動、後輪駆動、前輪駆動-後輪追従、後輪駆動-前輪追従、4WDフルタイム及び4WDリジットが存在する。車種が前輪駆動(FWD)では、駆動輪である図6(a)の前輪側のローラのみ回転する場合と、図6(c)の前輪側のローラ及び前輪のローラ回転に後輪側のローラが追従する場合がある。
同様に、車種が後輪駆動(RWD)の場合、図6(b)又は(d)、車種が四輪駆動(RWD)の場合図6(e)又は(f)となる。
一方、燃費や排ガスなどの計測時には、シャシーダイナモメータのローラが設置される場所(試験現場)と試験のための操作卓の設置位置は、一般には操作者の安全や騒音等の作業環境を考慮して別室に設置されるため、操作卓側で操作者が実際に動作するローラの動作状況と車種との組み合わせが一致しているか否かの確認ができない問題を有している。
さらに、仮に操作卓とシャシーダイナモメータが同室に設置されていても、シャシーダイナモメータのローラはピット内(地下)に設置されており、かつ、車のタイヤ部分には安全柵が設置される場合もあるため目視での確認は困難となっている。
したがって、試験を開始しようとするとき、試験する車種と使用するローラの組み合わせが一致しているか否かの確認、又は冷却ファンのオン・オフ状態などの機器の動作状態の確認が困難であった。
なお、特許文献1にはメカニカルロス計測結果の画面例などが記載されているが、試験する車種の選択や、選択した車種に伴い使用されるローラの決定及び表示方法についての記載はない。
前記制御装置部の設定を行う操作表示画面にシャシーダイナモメータの設定状態として前後ローラの使用/不使用を表示する状態表示機能部を有することを特徴とするものである。
図1において、メインメニュー表示部は、メニュー機能部1、シャシーダイナモメータの状態表示機能部2、操作ロック機能部3、モード設定機能群4及び機器のオン・オフ切換機能群5を備え、これら各機能部はマウスによるクリック若しくはタッチパネルの操作によって選択される。
シャシーダイナモメータの状態表示機能部2は現在設定されているシャシーダイナモメータの設定状態を表示する領域で、前後ローラの使用/不使用の表示領域21、車速表示領域22及び冷却ファン使用/不使用の表示領域23を有している。
操作ロック機能部3は、モード設定機能群、オン・オフ設定切換機能群の操作を有効・無効に切換えるものである。なお、この操作ロック機能部3を使用することにより、例えば入力装置としてタッチパネル等を使用した場合の誤操作を防止することができる。
更に、この車種選択の表示画面(図2~4)には、現在の車種、並びに使用ローラの設定状態を視覚的に捉えるための現在設定表示部44と変更中の設定状態を視覚的に捉えるための設定変更中表示部45を備え、これら41~45で構成される車種選択の表示画面は、メインメニュー表示部と同時に一画面上に表示される。なお、6つの選択部(41a,41b,42a,42b,43a,43b)のうち、駆動方式が選択されたときにコントラストを変更するように設定するが、その他当該選択部の色別等で表現してもよい。
操作者が制御装置端末PCの電源を投入し、図1で示す操作表示画面が表示されると、メインメニュー表示部の状態表機能部2で現在設定されているシャシーダイナモメータの設定状態が表示される。例えば、前回試験時の車種が前輪駆動車で、シャシーダイナモメータのローラが前輪駆動のみのローラを選択していた場合には、状態表機能部2のローラのうち前輪用ローラのみのコントラストが明るくなり(図では斜線状態で表示)、後輪用ローラと異なった状態となって表示される。
これにより、変更後の機器構成である4WDフルタイムの機器構成の使用状態が、制御装置端末から制御装置部に送信され、制御装置部において操作変更後の機器構成使用状態が確認され、確認後制御装置部から制御装置端末部にアンサーが帰ってくると図3で示すように、現在設定表示部44から45側への矢印が表示され、変更される4WDフルタイムの画面が設定変更中表示部45に表示される。
また、変更時には、設定前後を表示する表示部44、45が同一画面上で、且つ隣り合った位置にローラ選択部41a,41b、42a,42b及び43a,43bが配置された状態となっているので、設定変更が容易となり操作性が向上するものである。
なお、図1の状態表示機能部2の前後ローラの使用/不使用の表示領域21の使用ローラは、使用ローラを選択した時点ではコントラストが明るくなった状態等で表示され、さらに実際に試験中に前記ローラが回転する場合には、アニメーション機能により回転中である旨を表示することもできる。
さらに、モード設定機能群4及び機器のオン・オフ切換機能群5をメインメニュー表示部に設けたことにより、シャシーダイナモメータや補機が設置される試験室より離れた位置に設けられる制御装置端末部での前後輪用ローラの選択、制御、確認を可能とすることで、試験現場に出向くことなく操作室で確認可能となる。これによって、操作者の試験時の作業性及び安全性の向上を図っている。
さらに、被試験車両の車速についても、図1における状態表機能部2の速度表示領域22に数値で表示される。
なお、実施例は制御装置部と制御装置端末部に分けて説明したが、制御装置部本体に制御装置端末部の機能を持たせても良いことはもちろんのことである。
更に、変更時の設定前後を表示する設定表示部は同一画面上で、且つ隣り合った位置にローラ選択部が配置された状態となっているので、設定変更が容易となり操作性が向上するものである。
また、操作者が現場から離れた位置でローラの動作状態が確認できるため、操作者の安全や騒音等の問題が無い作業環境を確保できる。
