Problems solved by technology

In addition, since the operator cannot personally modify the velocity characteristics of the actuator, the operator cannot actually adjust the velocity characteristics of the actuator
However, in machines that include hydraulic brake systems, the operator can use the HMI display to individually adjust the speed characteristics of the actuators, which cannot be achieved in conventional machines

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 actuator maximum speed value 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.

Description

technical field [0001] The present invention relates to a method of operator self-adjustment using an electrohydraulic actuator system. More particularly, the present invention relates to a method of operator self-adjustment utilizing an electrohydraulic actuator system, wherein an operator may display an instrument through a human machine interface (HMI) in a machine comprising a plurality of electrohydraulic actuator systems, Individually tune the look-up table of joystick commands versus actuator velocity commands so that the operator can individually tune the acceleration characteristics of the actuator to the desired actuator velocity characteristics, unlike existing fixed actuators that only include Machines with different actuator speed characteristics. Background technique [0002] In machines that include conventional hydraulic actuator systems, once the spool valve design is established, the actuator velocity characteristics cannot be modified without replacing th...
