Title
(EN) HYBRID WORKING VEHICLE
(FR) VÉHICULE DE CHANTIER HYBRIDE
(JA) ハイブリッド式作業車両
Abstract
(EN)
Provided is a hybrid working vehicle in which the operating efficiency is high even if the output power of a hybrid system for the power required for the vehicle is limited by the output limitation of an electricity storage device, or the like. The hybrid working vehicle is equipped with: a travel unit which has a traveling motor (9); a hydraulic working unit which has a hydraulic pump (4); and a control device (20) which has an operation determination unit (30) and a power calculation unit (31). The operation determination unit (30) receives the manipulated variable of an operating lever device, the amount of depression of an accelerator pedal and a brake pedal, and vehicle speed, and determines the current operating state of the vehicle. The power calculation unit (31) receives the output value of an engine (1) and the output value of an electricity storage device (11), and calculates and controls the power of the travel unit and the power of the hydraulic working unit. When the operation determination unit (30) determines that the current operating state of the vehicle is excavation work, which is the combination operation of the travel unit and the hydraulic working unit, the power calculation unit (31) calculates and controls the output (Prun) of the travel unit and the output (Pf) of the hydraulic working unit so that the sum of the output value (Pe) of the engine (1) and the output value (Pc) of the electricity storage device (11) becomes a preset distribution ratio.

L'invention concerne un véhicule de chantier hybride dont l'efficacité de fonctionnement est élevée même si la puissance de sortie d'un système hybride pour la puissance requise pour le véhicule est limitée par la limitation de sortie d'un dispositif de stockage d'électricité, ou analogue. Le véhicule de chantier hybride est équipé : d'une unité de déplacement qui a un moteur de déplacement (9) ; d'une unité de travail hydraulique qui présente une pompe hydraulique (4) ; et d'un dispositif de commande (20) qui a une unité de détermination d'opération (30) et une unité de calcul de puissance (31). L'unité de détermination d'opération (30) reçoit la variable manipulée d'un dispositif de levier d'actionnement, la quantité d'enfoncement d'une pédale d'accélérateur et d'une pédale de frein, et la vitesse du véhicule, et détermine l'état de fonctionnement actuel du véhicule. L'unité de calcul de puissance (31) reçoit la valeur de sortie d'un moteur (1) et la valeur de sortie d'un dispositif de stockage d'électricité (11), et calcule et commande la puissance de l'unité de déplacement et la puissance de l'unité de travail hydraulique. Lorsque l'unité de détermination d'opération (30) détermine que l'état de fonctionnement actuel du véhicule est un travail d'excavation, qui est le fonctionnement combiné de l'unité de déplacement et de l'unité de travail hydraulique, l'unité de calcul de puissance (31) calcule et commande la sortie (Prun) de l'unité de déplacement et la sortie (Pf) de l'unité de travail hydraulique, de telle sorte que la somme de la valeur de sortie (Pe) du moteur (1) et de la valeur de sortie (Pc) du dispositif de stockage d'électricité (11) devient un rapport de distribution prédéfini.
