AI Technical Summary

Technical Problem

The fault diagnosis and alarm functions of the existing electric swing system of excavators are relatively basic and lack intelligent management. This results in scattered fault information, high driver dependence, and an inability to take timely and differentiated protection measures, posing safety hazards.

Method used

By providing appropriate handling methods that match the severity level of a fault when it occurs, including precise alarms and automated processing, the vehicle electronic control unit (VECU) can query the fault data table to determine the severity level of the fault and generate corresponding alarms and handling strategies, thereby realizing a shift from passive alarms to proactive intelligent safety management.

Benefits of technology

It reduces reliance on driver experience, improves equipment operation safety and fault handling accuracy, and ensures equipment safety and reliability in complex operating environments.

Abstract

This application provides a fault handling method and a vehicle control system, comprising: starting an electric swing system and acquiring fault monitoring data of the electric swing system, the fault monitoring data including a target fault code; querying a fault data table to determine the fault severity level and fault handling strategy corresponding to the target fault indicated by the target fault code, the fault data table describing the mapping relationship between faults, fault severity levels, and fault handling strategies, the fault handling strategy describing the fault alarm method and fault handling rules under the corresponding fault severity level, the fault severity level being pre-classified according to the degree of impact of the fault on the electric swing system; and alarming and handling the target fault generated by the electric swing system according to the fault severity level and fault handling strategy corresponding to the target fault. This application reduces driver reliance on experience and improves equipment operation safety by providing a handling method matching the fault severity level when a fault occurs.
