摘　　要：本文主要以几何G6汽车常见低压系统故障作为研究对象,介绍了几何G6纯电动汽车无钥匙进入系统组成及低压上电控制逻辑,分析了电动汽车低压无法上电故障原因。通过CAN网络故障、射频接收模块故障、主继电器故障、刹车信号故障等典型故障案例揭示几何G6汽车低压无法上电故障现象,并针对故障现象对汽车故障进行分析诊断提出维修策略。This paper takes the common low-voltage system failure of Geometry G6 automobile as the research object,introduces the composition of the keyless entry system and the low-voltage power-up control logic of Geometry G6 pure electric vehicle,and analyzes the reasons why the low-voltage failure of electric vehicle cannot be powered up.Typical failure cases such as CAN network failure,RF receiver module failure,main relay failure,brake signal failure,etc.are used to reveal the phenomenon of low-voltage failure in Geometry G6.Analyze and diagnose the automobile faults according to the fault phenomena,and put forward the repair strategies.
