Flat ground control method and device, excavator and storage medium

The invention provides a flat ground control method and device, an excavator and a storage medium, and relates to the field of control. The ground leveling control method comprises the steps that the change rate of pilot pressure of a bucket rod handle is calculated; determining a land leveling mode according to the change rate of the pilot pressure; a control parameter for controlling the opening degree of a valve element of the bucket rod electric control valve and corresponding to the flat ground mode is searched; and according to the control parameters, the bucket rod electric control valve is controlled. The flat ground control logic of different operation habits of different users in different regions can be met. In addition, the problem of nodding or raising of the bucket rod in the ground leveling process can be solved, and the ground leveling performance is optimized. 本公开提供了一种平地控制方法、装置、挖掘机和存储介质，涉及控制领域。该平地控制方法包括：计算斗杆手柄的先导压力的变化率；根据先导压力的变化率，确定平地方式；查找与平地方式对应的控制斗杆电控阀的阀芯开度的控制参数；以及根据控制参数，控制斗杆电控阀。本公开能够满足不同地区
