基于电路回路原理的汽车灯光系统故障诊断

Trouble Diagnosis of Automotive Lighting System Based on the Principle of Current Circuit

在夜晚或昏暗条件下使用汽车灯光,可提高汽车行驶速度,确保行车安全。灯光系统的负载数量多,导线线路长,控制器件复杂等因素导致其故障率高,维修频繁,维修工工作量大。本文根据灯光系统电路回路原理,利用电流走向判断电路中各节点的故障,逐步检修,为汽车维修工提供参考及依据,对于今后的汽车电路维修工作有一定的指导意义。

Automotive light is used in the night or dark conditions, it is the guarantee of safety and the speed of travel at night. The lighting system has the largest number of loads, the length of the wire, the controller is complex and other factors, which lead to high failure rate and high frequent maintenance. The current loop lighting system principle, to determine the failure of each node in the circuit by the current gradually for maintenance, and provide reference basis for the vehicle maintenance industry, which has a certain guiding significance for the future of the automobile circuit maintenance work.
