Title:
FAULT-TOLERANT PROCESSING METHOD AND APPARATUS FOR WORKING MACHINE, AND WORKING MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/179270
Kind Code:
A1
Abstract:
The present application relates to the technical field of working machine control. Provided are a fault-tolerant processing method and apparatus for a working machine, and a working machine. The method comprises: acquiring a pressure signal, which is transmitted by a pressure sensor of a working machine; upon determining that the pressure signal is abnormal, determining a fault sensor corresponding to the abnormal pressure signal; determining a fault-tolerant strategy corresponding to the fault sensor; and obtaining a target output current on the basis of the fault-tolerant strategy, and sending the target output current to a main pump of the working machine, so as to control the working machine to continue operating. The present application is used for solving the defect in the prior art of a working machine being unable to complete a working condition operation in a timely manner due to the ceasing of the operation when a pressure sensor of the working machine malfunctions, such that operations can be continued even when the pressure sensor of the working machine malfunctions.
