Abstract:
(EN) A work vehicle control system comprises a sensor and a controller. The sensor outputs a signal indicating the actual travel direction of a work vehicle. The controller communicates with the sensor. The controller is programed so as to execute the following process. The controller acquires the actual travel direction of the work vehicle. The controller sets, as a target travel direction, the actual travel direction at the time when a condition indicating that the work vehicle has started to travel straight ahead has been satisfied. The controller calculates the difference in orientation between the target travel direction and the actual travel direction. The controller causes a work machine to move at a target tilt angle according to the difference in orientation so as to reduce the difference in orientation.
(FR) L'invention concerne un système de commande d'engin de chantier comprenant un capteur et un dispositif de commande. Le capteur émet un signal indiquant la direction de déplacement réelle d'un engin de chantier. Le dispositif de commande communique avec le capteur. Le dispositif de commande est programmé de manière à exécuter le processus suivant. Le dispositif de commande acquiert la direction de déplacement réelle de l'engin de chantier. Le dispositif de commande définit, comme direction de déplacement cible, la direction de déplacement réelle lorsqu'une condition est remplie indiquant que l'engin de chantier a commencé à se déplacer en ligne droite. Le dispositif de commande calcule l'écart d'orientation entre la direction de déplacement cible et la direction de déplacement réelle. Le dispositif de commande amène un engin de chantier à se déplacer selon un angle d'inclinaison cible, en fonction de l'écart d'orientation, de façon à réduire cet écart d'orientation.
(JA) 作業車両の制御システムは、センサとコントローラとを備える。センサは、作業車両の実際の進行方向を示す信号を出力する。コントローラは、センサと通信する。コントローラは、以下の処理を実行するようにプログラムされている。コントローラは、作業車両の実際の進行方向を取得する。コントローラは、作業車両が直進を開始したことを示す条件を満たしたときの実際の進行方向を、目標進行方向として設定する。コントローラは、目標進行方向と実際の進行方向との方位差を算出する。コントローラは、方位差を低減させるように方位差に応じた目標チルト角で作業機を動作させる。
