Abstract

Ce système de commande pour engin de chantier comprend : un corps rotatif ; une pompe qui refoule l'huile hydraulique ; un moteur rotatif qui est alimenté avec l'huile hydraulique provenant de la pompe et fait tourner le corps rotatif ; un capteur de rotation qui détecte la vitesse de rotation du corps rotatif ; et un dispositif de commande. Le dispositif de commande : calcule un débit de consommation indiquant un débit de l'huile hydraulique passant à travers le moteur rotatif sur la base de données de détection provenant du capteur de rotation ; calcule, sur la base du débit de consommation, un premier débit de demande de moteur rotatif indiquant un débit d'huile hydraulique demandée par le moteur rotatif pour maintenir un état d'accélération lorsque la vitesse de rotation du corps rotatif est dans l'état d'accélération ; et commande, sur la base du premier débit de demande de moteur rotatif, un débit de pompe indiquant le débit de l'huile hydraulique refoulée par la pompe.
