DRIVER SELF-TUNING METHOD USING ELECTRO-HYDRAULIC ACTUATOR SYSTEM

摘要

The present invention relates to a driver self-tuning method using an electro-hydraulic actuator system, the method comprising: a step in which a specific EHA system is selected by a HMI; a step of displaying a graph defining the mapping relationship of an actuator speed command with respect to a joystick command of the selected EHA system; a step in which, when a predetermined button is pressed by a user, the actuator maximum speed is tuned by multiplying the maximum speed value of the actuator of the selected EHA system, which has been pre-stored, by gain that increases or decreases in proportion to the number of times the button was pressed; and a step of storing the tuned actuator maximum speed in the upper controller of the EHA system. Equipment using the electro-hydraulic actuator system makes it possible to directly tune actuator speed characteristics that cannot be achieved with existing equipment using, by way of example, HMI display equipment and operating buttons.

1. An operator self-tuning method using an electro-hydraulic actuator system comprising:
a step of allowing a human machine instrument (HMI) to select any one of a plurality of electro-hydraulic actuator (EHA) systems in response to a user's manipulation; a step of displaying a graph in which a mapping relationship of a joystick command vs. an actuator speed command of the selected EHA system is defined; a step of, if a predetermined button (or key) is pressed by the user, tuning a maximum speed of a corresponding actuator by multiplying a pre-stored maximum speed value of an actuator of the selected EHA system by a gain that is increased or decreased in proportion to the number of pressings of the button (or key); and a step of storing the tuned maximum speed of the actuator in an upper controller of the corresponding EHA system.
