开闭斗液压控制方法及系统、工程机械、控制器及介质

本发明公开了一种开闭斗液压控制方法及系统、工程机械、控制器及介质，该开闭斗液压控制方法包括：获取输入设备的开闭斗输入信号，并根据开闭斗输入信号判断开闭斗阀芯是否满足预设开度条件，若开闭斗阀芯满足预设开度条件，通过增压电磁阀以预设的维持时长限制溢流模块的溢流流量，并控制供油模块以维持时长进行增压泵油。可见，本发明能够通过当前开闭斗输入信号和预设开度条件，判断出开闭斗阀芯的开度状态是否为正在执行铲斗打开动作的状态，在确定为该状态后通过增压电磁阀限制溢流模块的溢流流量，并使供油模块开始进行维持时长的增压泵油，以此在需要打开铲斗避免因溢流而导致出现铲斗打开动作缓慢的现象，从而提高了整机的可控性。
