摘要
针对汽车侧窗水污染问题,通过改进前风窗挡水条的关键参数,结合某款SUV车型不同前风窗挡水条的汽车环境风洞试验结果,利用图像处理技术定量分析前侧窗和外后视镜镜面区域的水污染面积,给出一种综合考虑侧向和后向视野的评价方法。结果表明,增加前风窗挡水条高度及储水面积均可减少流向侧窗的水量,弱化侧窗水污染,最终获得视野更优且工程可实现的前风窗挡水条方案。
The rainwater pollution on vehicle side window affects driver’s safety critically,it is necessary to study this kind of water management situations.By improving the key parameters of windshield water bar,and in combination of vehicle climate wind tunnel test results of different windshield water bars of a SUV,this article quantiataively analyzes water pollution area of the front side window and the exterior rear view mirror area by image processing technology,and proposes an evaluation method considering the lateral and rearview field comprehensively.It is found that increasing the height of the windshield water bar and the water storage area can reduce the water flow to the side window and weaken the water pollution of the side window.Finally,a water bar scheme for the front wind window with better visual field and engineering feasibility is obtained.
