汽车三合一控制器异响故障的检查与排除

Inspection and Elimination of Abnormal Noise in Three in One Controller of Automobile

从汽车实际故障角度出发,以三合一控制器出现异响为例,从三合一控制器模块异响故障的产生原因进行分析,找出PN结容易出现故障的主要原因,提出屏蔽反向电压,排除外部加装电器产生的电压干扰的应对措施,保证了三合一控制器模块的正常工作。

From the Angle of the automobile actual fault,triad controller appears sound,for example,from the triad controller module fault reasons were analyzed,and the sound is easy to find the PN junction of the main causes of malfunction,shielding reverse voltage is put forward,to exclude external equipped with electric voltage interference measures,to ensure the normal work of the triad controller module.
