Title (EN) ADAPTIVE UNDERSPEED CONTROL
(FR) COMMANDE DE SOUS-VITESSE ADAPTATIVE
Abstract:
(EN) A machine (100) includes an engine (102) connected to an implement pump (204) operating an actuator and to a propel pump operating a motor (106). An electronic controller (218) is disposed to receive at least one parameter selected from the group of: a pressure of fluid at the at least one motor (106), a pressure of fluid at the at least one implement actuator, a rate of rotation of the engine (102), a rate of rotation of the at least one motor (106), and a torque output of the engine (102). The electronic controller (218) monitors the at least one parameter for a predetermined period, and determines an operating mode of the machine (100). The electronic controller (218) then adjusts an underspeed setting for the engine (102) based on the operating mode.
(FR) Une machine (100) comprend un moteur à combustion interne (102) relié à une pompe d'accessoire (204) qui actionne un actionneur et à une pompe de propulsion qui actionne un moteur (106). Un contrôleur électronique (218) est disposé pour recevoir au moins un paramètre sélectionné dans le groupe consistant en : une pression de fluide dans le ou les moteurs (106), une pression de fluide dans le ou les actionneurs d'accessoire, une vitesse de rotation du moteur à combustion interne (102), une vitesse de rotation du ou des moteurs (106) et une sortie de couple du moteur à combustion interne (102). Le contrôleur électronique (218) surveille le ou les paramètres pendant une période prédéterminée, et détermine un mode de fonctionnement de la machine (100). Le contrôleur électronique (218) ajuste ensuite un réglage de sous-vitesse pour le moteur à combustion interne (102) sur la base du mode de fonctionnement.
