Abstract
(EN) A steering mechanism (66) controls the traveling direction of a motor grader (100). A direction correction input unit (36) is operated by an operator. A controller (40) controls the steering mechanism (66) so that the traveling direction is adjusted by a certain angle to the left or the right on the basis of an input operation command from the direction correction input unit (36), in a state of automatically controlling the steering performed by the steering mechanism (66).
(FR) Un mécanisme de direction (66) commande la direction de déplacement d'une niveleuse motorisée (100). Une unité d'entrée de correction de direction (36) est actionnée par un opérateur. Un dispositif de commande (40) commande le mécanisme de direction (66) de telle sorte que la direction de déplacement est réglée selon un certain angle à gauche ou à droite sur la base d'une instruction d'opération d'entrée provenant de l'unité d'entrée de correction de direction (36), dans un état de commande automatique de la direction effectuée par le mécanisme de direction (66).
(JA) 操向機構(66)は、モータグレーダ(100)の進行方向を操作する。方向修正入力部(36)は、オペレータにより操作される。コントローラ(40)は、操向機構(66)による操向を自動制御している状態で、方向修正入力部(36)の入力操作指令に基づいて進行方向を左右のいずれかに一定角度調整するように操向機構(66)を制御する。
