Title:
ENGINE ROTATING SPEED CONTROL METHOD AND APPARATUS, AND ENGINEERING MACHINERY
Document Type and Number:
WIPO Patent Application WO/2022/247335
Kind Code:
A1
Abstract:
An engine rotating speed control method for engineering machinery. The engine rotating speed control method comprises: obtaining an action execution sequence of engineering machinery in one operation period (S101); determining an action duration corresponding to each action in a plurality of actions in the operation period (S102); obtaining torque information of each action (S103); determining a target rotating speed of the engine corresponding to each action on the basis of the torque information and a relationship between a torque and a rotating speed under a preset optimal fuel consumption (S104); and controlling the rotating speed of the engine according to the action execution sequence, the action duration corresponding to each action, and the target rotating speed when the engineering machinery repeatedly executes the operation period (S105). According to the method, the energy consumption of the engine can be reduced, the continuity of the action in the operation process is ensured, the operation effect is guaranteed, periodic control of the rotating speed of the engine is achieved, independent regulation and control of each operation period are not needed, and the control mode is simpler and more convenient, thereby facilitating engineering applications. Also provided are an engine rotating speed control apparatus for engineering machinery, the engineering machinery, and a computer-readable storage medium.
