Method and device for controlling walking deviation of excavator
The invention discloses a control method and device for walking deviation of an excavator, and the control method comprises the steps: obtaining a first pilot pressure of a left walking pedal and a second pilot pressure of a right walking pedal when the left walking pedal and the right walking pedal tread to the maximum depth at the same time; when it is determined that the excavator walks linearly, reference current set values of a first main pump electromagnetic valve and a second main pump electromagnetic valve are calculated according to the first pilot pressure and the second pilot pressure; the excavator is controlled to walk based on the reference current set value, and the output pressure of the first main pump and the output pressure of the second main pump are obtained; and judging whether the excavator runs off-tracking or not according to the output pressure of the first main pump and the output pressure of the second main pump, and adjusting the final current set value of the first main pump electromagnetic valve or the second main pump electromagnetic valve when judging that the excavator runs off-tracking. According to the technical scheme, the problem of walking deviation of the excavator is solved, control logic is simple and accurate, labor cost is reduced, and meanwhile the working efficiency of the excavator is improved.
本发明公开了一种挖掘机行走跑偏的控制方法及装置，该控制方法包括：获取左行走踏板和右行走踏板同时踩到最大深度时，左行走踏板的第一先导压力和右行走踏板的第二先导压力；当确定挖掘机进行直线行走时，根据第一先导压力和第二先导压力计算第一主泵电磁阀和第二主泵电磁阀的基准电流设定值；基于基准电流设定值控制挖掘机行走，并获取第一主泵的输出压力和第二主泵的输出压力；根据第一主泵的输出压力和第二主泵的输出压力判断挖掘机是否行走跑偏，并在判定挖掘机行走跑偏时，调整第一主泵电磁阀或第二主泵电磁阀的最终电流设定值。以上技术方案，以解决挖掘机行走跑偏问题，控制逻辑简单准确，减少人力成本，同时提高挖掘机工作效率。
