Title:
WORK VEHICLE AND METHOD FOR CONTROLLING WORK VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/003763
Kind Code:
A1
Abstract:
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.
