As a result, in the state where the second image P2 is displayed, the first image P1 and the second image P2 are predetermined until there is either an input for canceling the output restriction or an input for allowing the output restriction to continue. Are alternately displayed on the screen 21D of the monitor 20 at every time (in this embodiment, every standby time tc). By doing in this way, the monitor 20 can prompt the operator of the work vehicle 1 to input any one of whether to cancel the output restriction.
- step S110 when there is no input for canceling the output restriction while the third image P3 is displayed on the screen 21D (step S110, No), the process proceeds to step S116.
- step S116 the display control unit 22 determines whether or not there is an input that does not release the output restriction, that is, an output restriction continuation permission input.
- step S116 the output restriction continuation permission input is generated when the switch F5 is pressed while the third image P3 shown in FIG. 6 is displayed on the screen 21D.
- step S116 If there is an output permission continuation permission input (step S116, Yes), the display control unit 22 returns to step S107 and executes the subsequent processing. When there is no input that does not release the output restriction (No at Step S116), the display control unit 22 repeats Step S109 and Step S110. In this way, in the work vehicle 1, a process for canceling or continuing the output restriction of the engine 29 or the like is executed.
Abstract
Description
図1は、本実施形態に係る作業車両1の一例を示す図である。作業車両1は、例えば、油圧ショベル、ダンプトラック、ホイールローダ、ブルドーザ又はフォークリフト等であるが、これらに限定されるものではない。作業車両1は、制御装置としてのエンジン制御装置10と、作業車両用表示装置としてのモニタ20と、内燃機関としてのエンジン29と、エンジン29が排出した排気ガスを処理する排気ガス処理装置30とを備える。この他に、作業車両1は、通信装置24と、位置検出装置25と、エンジン制御装置10と、車内信号線28と、燃料タンク31と、尿素水タンク32と、走行装置33と、蓄電器34と、オルタネータ35と、キースイッチ36と、情報収集装置37と、回転速度検出センサ38と、液体の量を検出する検出器としての液面検出センサ39F、39Aとを含む。液体の量を検出する検出器として、例えば液体に浮かべたフロートを検出することで液面の高さをとらえることが可能な超音波センサを用いることができる。また、液面を検出するのではなく、液体の量を直接計測するような液量センサ等、他の検出器を用いて液体の量を検出するようにしてもよい。
エンジン制御装置10は、エンジン29及び排気ガス処理装置30を制御する。エンジン制御装置10は、処理部11と、記憶部12と、入出力部13とを含む。処理部11は、例えば、CPU(Central Processing Unit)とメモリとを組み合わせたものである。記憶部12は、例えば、RAM(Random Access Memory)、ROM(Read Only Memory)、フラッシュメモリ若しくはハードディスクドライブ等又はこれらを組み合わせたものである。記憶部12は、エンジン29の制御及び排気ガス処理装置30の制御といった各種の処理を処理部11が実行するために必要なコンピュータプログラム及びデータ等を記憶している。次に、処理部11についてより詳細に説明する。
モニタ20は、画像を表示する装置である。モニタ20は、表示部21と、表示制御部22とを含む。モニタ20は、作業車両10の図示しない運転室内に設置される。本実施形態において、モニタ20は、例えば、作業車両1の各種の情報を画像として表示部21に表示する。モニタ20の画面に表示される作業車両1の情報としては、例えば、前述した燃料及び尿素水の残量の他、エンジン29を冷却する冷却水の温度、油圧ポンプ29OPが吐出する作動油の温度、作業車両1の累積稼働時間並びに各種の警報及びエラーコード等がある。
通信装置24は、アンテナ24Aを備えている。通信装置24、位置検出装置25、情報収集装置37は、通信処理装置37Tに組み込まれている。通信処理装置37Tは、車内信号線28と電気的に接続されている。通信装置24は、作業車両1の外部と通信することができる。本実施形態において、通信装置24は、例えば通信モデムである。通信装置24は、各種の制御装置、各種のセンサ、通信端末及び通信モデムを有する。通信装置24は、アンテナ24Aによって無線通信を行う。通信装置24に接続された情報収集装置37は、例えば、作業車両1が備えるセンサ類、エンジン制御装置10及びモニタ20等から作業車両1の稼働情報を収集し、通信装置24及びアンテナ24Aを介して外部に送信する。また、通信装置24は、外部の管理装置から作業車両1に送信される情報を受信する。
位置検出装置25は、GPS用アンテナ25Aを備えている。GPS用アンテナ25Aは、GPS(Global Positioning System)を構成する複数のGPS衛星から出力された電波を受信する。GPS用アンテナ25Aは、受信した電波を位置検出装置25に出力する。位置検出装置25は、GPS用アンテナ25Aが受信した電波を電気信号に変換し、自身の位置情報、すなわち位置検出装置25の位置を算出(測位)することにより、位置検出装置25が搭載された作業車両1の位置情報を求める。位置情報は、作業車両1の位置に関する情報であり、緯度、経度又は高度の座標である。位置検出装置25が自身の位置を計測するためには、GPS衛星に限らず他の測位用衛星によるものでもよい。すなわち、GNSS(全地球航法衛星システム:Global Navigation Satellite System)による位置計測ができればよい。位置検出装置25によって得られた作業車両1の位置情報は、作業車両1の稼働情報とともに通信装置24によって作業車両1の外部へ送信される。
車内信号線28は、例えば、CAN(Controller Area Network)である。車内信号線28に接続されたエンジン制御装置10、モニタ20及び通信処理装置37T等の電子機器は、車内信号線28を介して相互に通信することができる。本実施形態においては、これらの電子機器の他に、作業車両1の油圧システムを制御する制御装置、作業車両1の走行装置33を制御する制御装置及び作業車両1が備える各種センサを制御する装置等の電子機器が電気的に接続されている。車内信号線28に電気的に接続されている電子機器同士は、車内信号線28を介して通信することができる。
走行装置33は、エンジン29が発生した動力によって作業車両1を走行させる。本実施形態において、走行装置33は、油圧モーター33Mと履帯33Cとを含む。油圧モーター33Mは、エンジン29によって駆動される油圧ポンプ29OPから供給される作動油によって回転する。油圧ポンプ29OPは、図示しないポンプ制御装置によって作動油の吐出量が制御される。走行装置33は、油圧モーター33Mが履帯33Cを回転させることによって作業車両10を走行させる。走行装置33は、履帯33C等を備えたものには限定されない。例えば、エンジン29の動力を、トルクコンバーター及び変速装置を介して車輪に伝達するような装置であってもよい。
作業車両1は、蓄電器34を備える。蓄電器34は、例えば、鉛蓄電池又はニッケル水素蓄電池等の二次電池である。蓄電器34は、エンジン29を始動させるためのスターターモーターに電力を供給したり、モニタ20を始めとした、作業車両1が備える各種の電子機器に電力を供給したりする。蓄電器34は、オルタネータ35が発電した電気によって充電される。オルタネータ35は、エンジン29の駆動に連動して駆動することにより発電する。オルタネータ35が発電した電気は、蓄電器34に充電される。
蓄電器34から供給される電力は、キースイッチ36を介して、例えば図示しないスタータ、エンジン制御装置10、モニタ20及び通信処理装置37T等の電子機器に供給される。キースイッチ36は、蓄電器34に電気的に接続され、さらにキースイッチ36は、エンジン制御装置10、モニタ20及び通信処理装置37Tに電気的に接続されている。キースイッチ36としては、シリンダ錠を用いたもの、押しボタン式のもの又は無線通信を利用したイモビライザキー等を用いることができる。キースイッチ36がONになると、蓄電器34から、エンジン制御装置30、モニタ20及び通信処理装置37Tに電力が供給される。キースイッチ36がOFFになると、蓄電器34からエンジン制御装置10、モニタ20及び通信処理装置37Tに供給される電力が遮断される。
エンジン制御装置10がエンジン29等の出力を制限している場合、出力の制限についての解除回数又は解除時間の制約を定めた上で、条件によっては出力の制限を一時的に解除できる。本実施形態において、モニタ20は、エンジン制御装置10がエンジン29等の出力を制限しており、かつ出力の制限を一時的に解除できる場合には、その旨を画面21Dに表示する。このようにすることで、作業車両のオペレータは、エンジン29等の出力が制限されている場合において、前述した出力の制限を解除できるか否かを把握できるので、利便性が向上する。次に、出力の制限を一時的に解除できることについての情報を表示する処理について、モニタ20の画面21Dに表示される画像に対応付けて説明する。
図8は、エンジン29等の出力の制限を解除する処理の一例を示すフローチャートである。図1に示すモニタ20の画面21Dには、図2に示す稼働状態表示画像PSが表示されている。作業車両1に何らかの異常が発生した場合(ステップS101、Yes)、ステップS102においてエンジン制御装置10は、エンジン29等の出力を制限する。図1に示す表示制御部22は、モニタ20の画面21Dの表示を、例えば、図3に示すようなエラーコード49を含む稼働状態表示画像PSAに切り替える。作業車両1に異常が発生しない場合(ステップS101、No)、処理は終了する。
