Abstract:
(EN) A storage device stores leakage flow rate data. The leakage flow rate data defines a relationship between a leakage flow rate of hydraulic oil in a hydraulic circuit and a differential hydraulic oil pressure between a first drive circuit and a second drive circuit during stall. A controller communicates with the storage device. The controller determines a target tractive force for the vehicle. The controller determines, from the target tractive force, a target differential pressure that is a target value for the differential pressure. The controller references the leakage flow rate data to determine a leakage flow rate from the target differential pressure. The controller determines a target flow rate for a traveling pump from the leakage flow rate.
(FR) La présente invention concerne un dispositif de stockage qui stocke des données de débit de fuite. Les données de débit de fuite définissent une relation entre un débit de fuite d’huile hydraulique dans un circuit hydraulique et une pression d’huile hydraulique différentielle entre un premier circuit d’entraînement et un deuxième circuit d’entraînement pendant une manœuvre. Un dispositif de commande communique avec le dispositif de stockage. Le dispositif de commande détermine une force de traction cible pour le véhicule. Le dispositif de commande détermine, à partir de la force de traction cible, une pression différentielle cible qui est une valeur cible pour la pression différentielle. Le dispositif de commande référence les données de débit de fuite pour déterminer un débit de fuite à partir de la pression différentielle cible. Le dispositif de commande détermine un débit cible pour une pompe de déplacement à partir du débit de fuite.
(JA) 記憶装置は、漏れ流量データを記憶している。漏れ流量データは、ストール時における、第1駆動回路と第2駆動回路との間の作動油の差圧と、油圧回路における作動油の漏れ流量との関係を規定する。コントローラは、記憶装置と通信する。コントローラは、車両の目標牽引力を決定する。コントローラは、目標牽引力から差圧の目標値である目標差圧を決定する。コントローラは、漏れ流量データを参照して、目標差圧から漏れ流量を決定する。コントローラは、漏れ流量から走行用ポンプの目標流量を決定する。
