发明名称 METHOD FOR CONTROLLING A HYDRAULIC SYSTEM OF A WORKING MACHINE
摘要 A method is provided for controlling a hydraulic system of a working machine. The hydraulic system includes a hydraulic machine for providing hydraulic fluid to one or more actuators of the working machine. The method includes receiving a signal requesting a pump pressure from the hydraulic machine based on the load pressure of a first actuator of the one or more actuators which first actuator has the highest load pressure of the one or more actuators, discriminating the pressure request from the first actuator provided that the first actuator is stalled due to overload or geometrical limitations, and controlling the hydraulic machine to provide to pump pressure based on the load pressure of a second actuator of the one or more actuators which second actuator is in operation and has the second highest load pressure of the one or more actuators, or, if no actuator in addition to the first actuator is present and in operation, controlling the hydraulic machine to provide a predetermined idle pump pressure.
