  • FLOW RATE DISTRIBUTION METHOD AND APPARATUS, AND OPERATION MACHINE
    Publication number: 20250052237
    Abstract: A flow rate distribution method and apparatus and a work machine. The flow rate distribution method includes: acquiring a current actual displacement of each working element on a work machine; performing time integration on a current speed of each working element to obtain a current target displacement of each working element; determining a current displacement deviation of each working element based on the current actual displacement of each working element and the current target displacement of each working element; and distributing a current pump control flow rate of the work machine based on the current displacement deviation of each working element. According to the flow rate distribution method, when a plurality of working elements of a work machine operate, a current pump control flow rate can be accurately distributed.
