Abstract
Description
すなわち、上記公報に開示された積荷重量計測装置では、空荷荷重を確実に計測することができるものの、モニタに数値として表示されるだけであるため、キャブ内の運転者が積荷の状態を直感的に認識することが困難である。
本発明の課題は、周辺監視用のモニタ画面を用いて、運転者に直感的に積荷状態を認識させることが可能なダンプトラックの積載量表示装置を提供することにある。
これにより、運転者は、モニタ画面を見ながら、荷台上にどの程度の積載量であるかを容易に認識することができる。
なお、積荷のイメージ部分に加えて、ダンプトラックの車体部分を着色して表示することで、積荷のイメージ部分との着色のコントラストをつけて、運転者が車両の積載状態をより分かり易くすることができる。
ここでは、積載量を検知する検知部として、ペイロードメータを用いている。
これにより、荷台上に載せられた積荷の重量を容易に検知することができる。
これにより、積荷の重量を直接的に受けるサスペンションシリンダにペイロードメータを設けることで、容易に積載量を検知することができる。
なお、以下の説明において、「前」「後」「左」「右」とは、運転席に着座して正面を向いている運転者から見た方向を基準とする方向を意味しており、「車幅方向」とは、「左右方向」と同義である。
本実施形態に係るダンプトラック1は、鉱山作業などに用いられる自走式の超大型作業車両であって、約5mを超える車幅を有している。
周辺監視装置10は、ダンプトラック1の周辺に存在する障害物の有無等を監視する装置であって、図2に示すように、6台のカメラ11~16と、コントローラ20と、ペイロードメータECU(検知部)21と、圧力センサ22と、ストロークセンサ23と、モニタ50と、を有している。
6台のカメラ11~16は、図3に示すように、ダンプトラック1の周囲360度範囲の画像を取得するためにダンプトラック1の外周部分にそれぞれ取り付けられている。なお、各カメラ11~16は、左右方向において120度(左右60度ずつ)、高さ方向において96度の視野範囲を有している。
以上の6台のカメラ11~16によれば、図5(a)に示すように、ダンプトラック1の周囲360度の全周囲を含む俯瞰画像200を取得することができる。また、6台のカメラ11~16は、それぞれ撮像した画像に対応する画像データをコントローラ20に送信する。
コントローラ20は、図2に示すように、各カメラ11~16、ペイロードメータECU21、モニタ50に接続されている。
ペイロードメータECU21は、図2に示すように、圧力センサ22およびストロークセンサ23に接続されており、圧力センサ22およびストロークセンサ23から受信したデータを用いて積載重量を計測する車載型荷重計(ペイロードメータ)として機能する。
なお、ペイロードメータECU21において算出された積荷の重量に基づく積載量表示制御については、後段にて詳述する。
本実施形態のダンプトラック1では、コントローラ20によって、図6に示すフローチャートに従って、モニタ50の画面上にベッセル4上の積荷の有無が表示される。
以上、本発明の一実施形態について説明したが、本発明は上記実施形態に限定されるものではなく、発明の要旨を逸脱しない範囲で種々の変更が可能である。
上記実施形態では、ダンプトラック1の荷台上の積荷の重量の検知結果に応じて、積荷がない状態(未積載状態)と積荷がある状態(積載状態)とを切り換える例を挙げて説明した。しかし、本発明はこれに限定されるものではない。
この場合には、運転者は、積荷の有無だけでなく、積荷の積載量まで直感的に認識することができる。
上記実施形態では、ダンプトラック1の荷台上の積荷の重量の検知結果に応じて、単に、積荷がない状態(未積載状態)と積荷がある状態(積載状態)とを切り換える例を挙げて説明した。しかし、本発明はこれに限定されるものではない。
なお、ダンプトラックの画像および積荷の画像については、上記色に限定されるものではなく、適宜、運転者が分かり易い警告色(黄、橙、赤等)に設定したり、運転者の好みで色を設定したりしてもよいし、画像部分を点滅させる等の手段によって運転者が認識し易いように表示してもよい。
上記実施形態では、本発明に係るダンプトラックの積載量表示装置が、周辺監視装置10の一部の機能として設けられている例を挙げて説明した。しかし、本発明はこれに限定されるものではない。
例えば、周辺監視装置と積載量表示装置とが別々に設けられていてもよい。
上記実施形態では、ダンプトラック1の積載量を検知する検知部として、ベッセル4に積載された積荷の重量を検知するペイロードメータECU21を用いた例を挙げて説明した。しかし、本発明はこれに限定されるものではない。
この場合には、積載重量を認識できないため段階的な積荷イメージの大きさの変更制御はできないものの、少なくとも積荷がある状態かない状態かについては認識することができる。このため、上記実施形態のように、積荷の有無を俯瞰画像上に表示することができるため、運転者は、モニタ画面を確認するだけで直感的に積荷の有無を確認することができる。
上記実施形態では、ペイロードメータECU21における検知結果に基づいて、積荷画像Cを含むダンプトラック1の画像1Gと、積荷画像Cを含まないダンプトラック1の画像1Gとを切り換えて表示する例を挙げて説明した。しかし、本発明はこれに限定されるものではない。
