Excavator control method and device, storage medium and excavator

ZHANG XIAOFENG / LUO JIANHUA / SHEN DEKANG

The invention provides an excavator control method and device, a storage medium and an excavator. Firstly, a correction coefficient is determined according to a current oil temperature and a correction curve. The correction coefficient represents the correction ratio of the torque of a hydraulic pump, and the correction curve contains the corresponding relationship between the oil temperature andthe correction coefficient. Then, obtained required torque is corrected according to the correction coefficient to obtain the target torque. A proportional valve of the hydraulic pump is adjusted according to the target torque. Considering the influence of oil temperature on oil, the problem of inconsistency of the actual output of the excavator is caused. The target torque is adjusted through thecorrection coefficient, and the shake is reduced at low temperature. At high temperature, it is guaranteed that the current output power can be matched with the requirement of a user, and the problems of slow action, low working efficiency and the like of the excavator are avoided.

本申请提出一种挖掘机控制方法、装置、存储介质及挖掘机。首先依据当前的油温和修正曲线确定修正系数。其中，修正系数表征液压泵扭矩的修正比例，修正曲线包含油温和修正系数的对应关系。再依据修正系数对获得的需求扭矩进行修正，以得到目标扭矩。然后依据目标扭矩对液压泵的比例阀进行调节。考虑到油温对油液的影响，从而会导致挖掘机的实际输出不一致的问题。通过修正系数，调节目标扭矩，在低温时，减少抖动；高温时，保障当前的输出功率能够与用户的需求匹配，避免产生挖掘机动作慢、工作效率降低等问题的出现。
