基于相关性分析法的吉利EV450整车控制系统故障分析
Fault analysis of geely EV450 vehicle control system based on correlation analysis method
摘要
Abstract
One of the common faults of new energy vehicles is that the electric vehicle cannot be powered on.Logical analysis was carried out with three examples of the power-on failure of the whole vehicle caused by the fault of the whole vehicle control system of Geely EV450.Starting from the fault phenomenon,the control logic was analyzed,the similarities and differences in the control circuit were looked for.By using the"correlation analysis method"for many times,the fault range was quickly narrowed,the speed of fault diagnosis and analysis was improved,which provided a reference for automobile detection and maintenance.关键词
