WORK MACHINE AND METHOD FOR CALIBRATING AN ELECTROHYDRAULIC PUMP IN AN OPEN CENTER HYDRAULIC SYSTEM
A work machine and method for a work machine with an open center hydraulic system for controlling actuation of an implement includes an implement control valve, an electro-hydraulically controlled pump, a hydraulic circuit coupled to the implement actuator, and a pressure transducer positioned for measuring a pressure in the hydraulic circuit between the pump and the implement control valve. A calibration system for calibrating the pump includes a controller having a non-transitory computer readable medium having a program instruction for causing a processor to calibrate a first pump threshold for the pump in a pump-flow curve wherein the first pump threshold including a minimum pump control signal to actuate the pump; determine a hysteresis band in the pump-flow curve; and calibrate a second pump threshold for the pump in the pump-flow curve wherein the second pump threshold including a maximum pump control signal to actuate the pump below a relief setpoint.
