Abstract: With the development of the automobile industry, people are becoming more and more intelligent requirements for vehicles, rain sensor has become an essential part of the automobile, at the same time in the rainy driving process, rain sensor can automatically control the wiper system and make the driver's attention more concentrated, without distraction to control the wiper system which improve the safety of driving. Therefore, this paper is mainly to study the strategy of the rainfall sensor in the process of automobile driving, from the working principle of the product, software algorithm logic, application conditions and other aspects of research and explanation, through the wiper strategy to achieve intelligent automatic wiper control, bring convenience to the driver, improve the use of vehicle comfort. Based on this software strategy, finally through the driving experience of test engineers and drivers, different rainfall conditions can be distinguished in a better area, which effectively improves the effect of automatic scraping, improves the stability of wiper control, and solves the problem of slow stop and scraping in tunnel mode.
