Control method and control device for excavator, controller and excavator
The embodiment of the invention provides a control method and device for an excavator, a controller and the excavator. The control method for the excavator comprises the steps that a walking direction selection signal of the excavator is obtained; determining a target walking electromagnetic valve according to the walking direction selection signal; acquiring a walking speed selection signal of the excavator; determining whether the value of the walking speed selection signal is greater than a first preset threshold; and under the condition that it is determined that the value is larger than the first preset threshold value, a valve element of the target walking electromagnetic valve is controlled to be in a full-open state. According to the embodiment of the invention, the valve core can be completely opened in advance, the throttling loss during half-opening of the valve core is reduced, and the walking economy of the excavator is improved.
本发明实施例提供一种用于挖掘机的控制方法及控制装置、控制器和挖掘机，用于挖掘机的控制方法包括：获取所述挖掘机的行走方向选择信号；根据所述行走方向选择信号确定目标行走电磁阀；获取所述挖掘机的行走速度选择信号；确定所述行走速度选择信号的值是否大于第一预设阈值；以及在确定所述值大于所述第一预设阈值的情况下，控制所述目标行走电磁阀的阀芯处于全开状态。本发明实施例可以使得阀芯提前全部开启，减少阀芯半开时的节流损失，改善挖掘机行走经济性。
