摘　　要：雾灯是雨雾天气行车的安全保障,整车开发阶段对雾灯控制功能及可靠性都要进行严格的测试验证。本文针对某车型整车路试中出现的雾灯偶发点亮故障,从雾灯系统软硬件工作原理出发,分析故障产生的原因,并提出解决方案,对软件进行优化设计,提高雾灯控制系统的鲁棒性。Vehicle fog lamps are used to ensure driving security in the serious weather like rain or fog. In the process of whole vehicle development, the test of fog control function and reliability is necessary. In the road test,there is a fog lamp occasional illuminated failure. Based on the hardware and software principle of the fog lamps,this paper analyzes the causes of the failure and puts forward the solution which improves the robustness of the control system of vehicle fog lamp by optimizing the software design.
