The invention provides a walking deviation rectifying method and system and a crawler-type working machine, and relates to the technical field of working machineries, the method is applied to the crawler-type working machine, and the method comprises the steps that state parameters including the running speed of a first crawler belt and the running speed of a second crawler belt of the crawler-type working machine during walking of the crawler-type working machine are obtained; on the basis of the running speed of the first crawler belt and the running speed of the second crawler belt, the walking deviation amount of the crawler-type operation machine is obtained; and based on the walking deviation amount, the current of a first proportional electromagnetic valve and/or a second proportional electromagnetic valve of the crawler-type operation machine is adjusted till the running speed of the first crawler belt is the same as the running speed of the second crawler belt. The method is used for overcoming the defect that in the prior art, only the walking deviation phenomenon caused by the difference of hydraulic pumps and the difference of oil ways between the hydraulic pumps and the corresponding walking motors can be corrected, and consequently walking deviation of the operation machine cannot be completely and effectively avoided, and accurate and effective correction of walking deviation of the operation machine is achieved.

    本发明提供一种行走纠偏方法、系统及履带式作业机械,涉及作业机械技术领域,该方法应用于履带式作业机械,包括:获取履带式作业机械行走时的包括履带式作业机械的第一履带的运行速度和第二履带的运行速度的状态参数;基于第一履带的运行速度和第二履带的运行速度,得到履带式作业机械的行走跑偏量;基于行走跑偏量,调整履带式作业机械的第一比例电磁阀和/或第二比例电磁阀的电流,直至第一履带的运行速度与第二履带的运行速度相同。该方法用以解决现有技术中仅能纠正因液压泵的差异及液压泵与对应行走马达之间油路的差异造成的行走跑偏现象,所造成不能完全有效避免作业机械行走跑偏的缺陷,实现作业机械行走跑偏的准确有效纠正。
