在雨中驾驶会导致视觉性能下降，汽车设计师提出了应对措施，以减少雨对驾驶性能的影响。在这篇文章中，我们提出了一种致力于定量估计由于降雨造成的视觉性能损失的方法。我们认为雨点落在挡风玻璃上是影响驾驶时视觉表现的主要因素。一项有40名参与者参加的实验室实验。考虑了两种驾驶任务：检测道路上的物体(对比度阈值)和阅读路标，雨导致视觉表现下降。这项实验是在实验室控制的人工降雨下进行的。比较了两种雨强水平，以及两种雨刷条件(新雨刷和旧雨刷)，而参考条件是不下雨。参考驾驶情况为夜间驾驶。研究还发现了雨量和雨刷特性的影响，从视觉效果的角度验证了所提出的定量估计雨对策的方法。(C)2013爱思唯尔有限公司。保留所有权利。
Driving through rain results in reduced visual performance, and car designers have proposed counter-measures in order to reduce the impact of rain on driving performance. In this paper, we propose a methodology dedicated to the quantitative estimation of the loss of visual performance due to the falling rain. We have considered the rain falling on the windshield as the main factor which reduces visual performance in driving. A laboratory experiment was conducted with 40 participants. The reduction of visual performance through rain was considered with respect to two driving tasks: the detection of an object on the road (contrast threshold) and reading a road sign. This experiment was conducted in a laboratory under controlled artificial rain. Two levels of rain intensity were compared, as well as two wiper conditions (new and worn), while the reference condition was without rain. The reference driving situation was night driving. Effects of both the rain level and the wipers characteristics were found, which validates the proposed methodology for the quantitative estimation of rain countermeasures in terms of visual performance.
