Electronic hydraulic pressure control apparatus and method using variable behavior
View Patent ↗The present disclosure relates to an electronic hydraulic pressure control apparatus and an electronic hydraulic pressure control method using a variable behavior, and more particularly, to an electronic hydraulic pressure control apparatus and an electronic hydraulic pressure control method using a variable behavior which can detect that a user manipulates an electronic joystick of an electronic hydraulic system to positive and negative positions with respect to a neutral point in a preset time period, and vary a behavior (for example, a general behavior or an abrupt operation behavior) according to the detection result, thereby enhancing both comfortableness of an operator and an abrupt operation efficiency in manipulating a construction machine and providing a convenience for an operator.
1. An electronic hydraulic pressure control apparatus using a variable behavior, comprising:
a signal input unit configured to receive a manipulation signal according to a manipulation of a user;
a manipulation state determining unit configured to analyze the received manipulation signal and determine any one of a general behavior mode and an abrupt operation behavior mode to output a mode selection signal;
a behavior mode changing unit configured to change a behavior mode to the general behavior mode or the abrupt operation behavior mode according to the output mode selection signal;
a signal processing unit configured to, according to the changed behavior mode, output the received manipulation signal in the abrupt operation behavior mode, and increase or decrease the received manipulation signal by a predetermined gain and output the increased or decreased manipulation signal in the general behavior mode; and
a proportional valve driving unit configured to drive a proportional valve according to a signal output by the signal processing unit,
wherein the manipulation state determining unit determines the behavior mode to be the abrupt operation behavior mode if the received manipulation signal is alternately repeated to positive and negative positions with respect to a neutral position by a predetermined number within a predetermined time period, and determines the behavior mode to be the general behavior mode if the received manipulation signal is continuously maintained in any one of a neutral position, a positive position and a negative position for a predetermined time period.
