左侧门车窗升降时右侧门车窗联动故障分析与改进

Analysis and Improvement of Right Door Window Linkage Failure When Left Door Window Lifter Working

针对某电动汽车开发中出现的接通左侧门车窗升降器开关时右侧门车窗玻璃联动的故障,对BCM电路进行详细分析,指出绘制整车电气原理图时电气部件原理图简化、成熟电气部件移植到新车型上的注意事项。

According to the failure about right door window glass lifter having linkage when the switch of left door window lifter is turned on,this paper analyzes the BCM circuits in detail,points out that the precau-tions when the schematic diagram of electrical components is simplified during drawing the whole vehicle schematic diagram and the precautions for transplanting mature electrical components to new models.
