复杂环境下汽车远近灯光智能切换系统设计

Accuracy Design on Intelligent Switching System of Automobile Headlight under Complex Environment

针对当前汽车会车行驶时,远近光灯使用不当问题,本文提出了一种基于复杂环境下汽车远近灯光智能切换系统,该系统使用的是STM32系列单片机。结合采集到的光照量、温湿度量以及烟雾浓度量,经过程序算法处理将得到的结果与设定的阈值比较,确定是否自动切换远近光灯,有效减少了灯光手动切换导致司机注意力的分散。通过实验验证,该系统造价低,体积小,稳定性好,能有效提高机动车驾驶安全性。

Automobile headlight are often inappropriate used when automobiles are crossing each other. An intelligent switching system of the automobile headlight was designed base on the complex environment which used the STM32 series microcontroller. Combine the value of the illumination, the temperature and humidity as well as the smog density. After the program algorithm processing the obtained results and the threshold were compared, whether switching far and near light of the automatic are determined. This effectively reduces the light led to distract the driver's manual switch. Confirms through the experiment, this system construction cost is low, the volume is small, the stability is good, the performance of motor vehicle driving safety is improved.
