(FR) ENGIN DE CHANTIER
(JA) 作業機械
Abstract:
(EN) The purpose of the invention is to provide a work machine installed with a semi-automatic control to assist controller operation with work to excavate ground according to a designed surface, wherein the work machine can assist in controller operation with rolling compaction, in which the ground is compacted according to the designed surface. Provided is a work machine 100 that comprises a control device 25 having a semi-automatic control unit 31 to correct a manipulated variable indicated by way of an operation device 15L, 15R, wherein the control device has: a rolling compaction determination unit 52 that determines whether a work tool 7 is pressing on the ground; and an actuator control correction unit 54 that further corrects the manipulated variable that has been corrected by the semi-automatic control unit so that the force applied by the work tool on the ground becomes larger when the rolling compaction determination unit determines that the work tool is pressing on the ground.
(FR) L'objectif de l'invention est de fournir un engin de chantier équipé d'une commande semi-automatique pour aider au fonctionnement du dispositif de commande avec des travaux d'excavation du sol selon une surface conçue, l'engin de chantier pouvant aider au fonctionnement du dispositif de commande avec un compactage à roulement, dans lequel le sol est compacté selon la surface conçue. L'invention concerne un engin de chantier 100 qui comprend un dispositif de commande 25 ayant une unité de commande semi-automatique 31 pour corriger une variable manipulée indiquée au moyen d'un dispositif d'actionnement 15L, 15R, le dispositif de commande comprenant: une unité de détermination de compactage à roulement 52 qui détermine si un outil de travail 7 presse sur le sol; et une unité de correction de commande d'actionneur 54 qui corrige en outre la variable manipulée qui a été corrigée par l'unité de commande semi-automatique de telle sorte que la force appliquée par l'outil de travail au sol devient supérieure lorsque l'unité de détermination de compactage à roulement détermine que l'outil de travail presse sur le sol.
(JA) 設計面通りに地面を掘削する作業で操縦者の操作を補助する半自動制御を搭載した作業機械において、設計面通りに地面を押し固める転圧作業で操縦者の操作を補助することができる作業機械を提供する。 操作装置15L,15Rによって指示された操作量を補正する半自動制御部31を有する制御装置25を備えた作業機械100において、前記制御装置は、作業具7が地面に押し付けられているか否かを判定する転圧判定部52と、前記作業具が地面に押し付けられていると前記転圧判定部が判定したときに、前記作業具が地面に加える力が大きくなるように、前記半自動制御部によって補正された操作量を更に補正するアクチュエータ制御補正部54とを有する。
