Abstract
(EN)
A controller (40) for a hydraulic shovel is provided with: a first speed arithmetic logic unit (43f) that computes a first speed for an arm cylinder (6) from the detection value of a manipulation amount detection device (52a); a second speed arithmetic logic unit (43d) that computes a second speed for the arm cylinder (6) from the detection value of an orientation detection device (50); and a third speed arithmetic logic unit (43e) that computes a third speed to be used as the arm cylinder (6) speed by an actuator control unit (81) executing machine control. The third speed arithmetic logic unit computes the third speed to be the first speed during the interval from when the manipulation amount detection device detects that an operation on an arm (9) has been input to a prescribed time t0, computes the third speed to be the speed computed from the first speed and the second speed during the interval from the prescribed time t0 to a prescribed time t1, and computes the third speed to be the second speed after the prescribed time t1.

La présente invention concerne un dispositif de commande (40) pour une pelle hydraulique. Ledit dispositif comprend : une première unité logique arithmétique de vitesse (43f) qui calcule une première vitesse pour un vérin de bras (6) à partir de la valeur de détection d'un dispositif de détection de quantité de manipulation (52a); une deuxième unité logique arithmétique de vitesse (43d) qui calcule une deuxième vitesse pour le vérin de bras (6) à partir de la valeur de détection d'un dispositif de détection d'orientation (50); et une troisième unité logique arithmétique de vitesse (43e) qui calcule une troisième vitesse à utiliser en tant que vitesse de vérin de bras (6) par une unité de commande d'actionneur (81) qui exécute une commande de machine. La troisième unité de logique arithmétique de vitesse calcule la troisième vitesse comme étant la première vitesse durant l'intervalle depuis l'instant auquel le dispositif de détection de quantité de manipulation détecte qu'une opération sur un bras (9) a été entré jusqu'à un temps prescrit t0, calcule la troisième vitesse comme étant la vitesse calculée à partir de la première vitesse et de la deuxième vitesse durant l'intervalle depuis le temps prescrit t0 jusqu'à un temps prescrit t1, et calcule la troisième vitesse comme étant la deuxième vitesse après le temps prescrit t1.
