Abstract:
(EN) A control system for a work vehicle comprises a controller. The controller acquires current topography data indicating current topography to be worked. The controller determines, on the basis of the current topography, a target design topography indicating a target trajectory for a work machine. The controller determines, on the basis of the current topography data, whether the current topography has an upward gradient or a downward gradient. The controller changes the target design topography in accordance with the result of the determination of the gradient.
(FR) L'invention concerne un système de commande pour un véhicule de chantier qui comprend un dispositif de commande. Le dispositif de commande acquiert des données topographiques actuelles indiquant la topographie actuelle sur laquelle un travail doit être effectué. Le dispositif de commande détermine, sur la base de la topographie actuelle, une topographie de conception cible indiquant une trajectoire cible pour un engin de chantier. Le dispositif de commande détermine, sur la base des données topographiques actuelles, si la topographie actuelle présente un gradient vers le haut ou un gradient vers le bas. Le dispositif de commande modifie la topographie de conception cible en fonction du résultat de la détermination du gradient.
(JA) 作業車両の制御システムは、コントローラを備える。コントローラは、作業対象の現況地形を示す現況地形データを取得する。コントローラは、現況地形に基づいて、作業機の目標軌跡を示す目標設計地形を決定する。コントローラは、現況地形データに基づいて、現況地形が上り勾配であるか、又は、下り勾配であるかを判定する。コントローラは、勾配の判定結果に応じて目標設計地形を変更する。
