The invention relates to the field of engineering vehicles, and discloses an excavator control method and an excavator. The control method comprises the steps that the load power of an excavator hydraulic system is calculated, and engine demand power is calculated according to the load power; according to the mapping relation between the engine rotating speed and the engine power, the engine rotating speed corresponding to the engine demand power is inquired, and the engine rotating speed is adjusted to the inquired engine rotating speed; according to the mapping relation between the operation mode of the excavator and the set flow of the hydraulic system, the set flow corresponding to the current operation mode is inquired; and the displacement of the hydraulic pump is calculated according to the inquired rotating speed of the engine and the set flow, and the displacement of the hydraulic pump is adjusted to the calculated displacement of the hydraulic pump. The displacement of the hydraulic pump and the power of the engine are dynamically matched, the rotating speed of the engine is self-adaptively adjusted according to the load, the displacement of the hydraulic pump is self-adaptively adjusted according to the adjusted rotating speed of the engine, and the action coordination and smoothness in the operation process of the excavator are improved.
本发明涉及工程车辆领域，公开一种挖掘机控制方法及挖掘机，控制方法包括：计算挖掘机液压系统的负载功率，根据负载功率计算发动机需求功率；根据发动机转速和发动机功率之间的映射关系，查询与发动机需求功率对应的发动机转速，将发动机的转速调节至查询到的发动机转速；根据挖掘机的作业模式与液压系统的设定流量之间的映射关系，查询与当前的作业模式对应的设定流量；根据查询到的发动机转速和设定流量计算液压泵排量，将液压泵的排量调节至计算出的液压泵排量。本发明对液压泵排量和发动机功率进行动态匹配，实现根据负载自适应调节发动机转速，根据调整后的发动机转速自适应调整液压泵的排量，提高挖掘机作业过程中的动作协调性和流畅性。
