Method for setting response modes of construction vehicle operation lever

Abstract

The present invention discloses a method for freely setting response modes of the operation lever of construction vehicle, according to driver's skills or proficiency and work characteristics, in which the method includes the steps of: receiving a mode signal from a mode selection means, and selecting one of a plurality of selection modes; receiving an operation signal from the operation lever; filtering the operation signal through a filter which is operating in response to the selected response mode; and outputting a filtered control signal.

1 . A method for setting response modes of an operation lever for construction vehicle comprising an actuator for driving a working apparatus using hydraulic fluid supplied from a hydraulic pump, a control valve for supplying the hydraulic fluid from the hydraulic pump to the actuator, an operation lever for generating an operation signal to drive the actuator, and a controller for changing the operation signal and generating a control signal therefrom to control the control valve, the method comprising the steps of: 
 receiving a mode signal from a mode selection means, and selecting one of a plurality of selection modes;    receiving the operation signal from the operation lever;    filtering the operation signal through a filter which is operating in response to the selected response mode; and    outputting a filtered control signal.    
   
   
       2 . The method according to  claim 1 , wherein the filter used for the filtering step is a low pass filter.  
   
   
       3 . The method according to  claim 2 , parameters applied to the filter for the filtering step are predetermined appropriate for the actuator which is driven by the operation lever and the respective response mode characteristics, and are stored in the controller.
