Abstract:
(EN) This work vehicle control system is equipped with a current topography acquisition device and a controller. The current topography acquisition device acquires current topography information indicating the current topography of the site where work is to be performed. The controller acquires the current topography information from the current topography acquisition device. In cases in which the current topography is located below the target topography for the site where work is to be performed, the controller generates a command signal for moving a work machine along a trajectory that is located a prescribed distance above the target topography.
(FR) Cette invention concerne un système de commande d'engin de chantier équipé d'un dispositif d'acquisition de topographie actuelle et d'un dispositif de commande. Le dispositif d'acquisition de topographie actuelle acquiert des informations de topographie actuelle indiquant la topographie actuelle du site où le travail doit être effectué. Le dispositif de commande acquiert les informations de topographie actuelle à partir du dispositif d'acquisition de topographie actuelle. Dans les cas où la topographie actuelle est située en dessous de la topographie cible pour le site où le travail doit être effectué, le dispositif de commande génère un signal de commande pour déplacer un engin de chantier le long d'une trajectoire qui est située à une distance prescrite au-dessus de la topographie cible.
(JA) 作業車両の制御システムは、現況地形取得装置と、コントローラと、を備える。現況地形取得装置は、作業対象の現況地形を示す現況地形情報を取得する。コントローラは、現況地形取得装置から現況地形情報を取得する。コントローラは、現況地形が作業対象の目標地形よりも下方に位置する場合、目標地形よりも、所定距離、上方に位置する軌跡に沿って作業機を移動させる指令信号を生成する。
