METHOD AND DEVICE FOR CONTROLLING MAIN CONTROL VALVE OF CONSTRUCTION MACHINERY
In a method of controlling a main control valve in construction machinery, a first joystick signal for controlling a first control valve device and/or a second joystick signal for controlling a second control valve device are received from one joystick. While one of the first and second control valve devices operates, whether or not a joystick signal for controlling another of the first and second control valve devices is inputted is determined. A weighted value is applied to a threshold of valve operation initiation with respect to a joystick displacement to determine a raised threshold of valve operation initiation. If the inputted joystick displacement satisfies the raised threshold of valve operation initiation, a valve stoke corresponding to the inputted joystick displacement is calculated and outputted.
