Abstract:
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.
