汽车智能刮水器控制系统设计方案

Design Scheme of Intelligent Wiper Control System for Vehicles

基于微控制器MC9S08系列单片机,通过红外雨量传感器采集雨量的大小,利用脉宽调制(PWM)技术对刮水电动机进行控制,提出一种集手自动于一体的智能刮水器控制系统设计方案。通过模块化思想进行了系统硬件设计和系统软件设计。实际试验结果表明,设计的智能刮水器控制系统可以有效实现刮水器手/自动工作模式,可取代传统机械结构的刮水器。

Through infrared rain sensor perceiving rainfall, applying PWM technology to control the speed of wiper motor, the design of intelligent wiper system based on the MCU MC9S08 is presented here, which can work automatically or manually. Hardware and software are designed based on the modularization thinking. Tests show that this system can actually achieve manual and automatic working mode and replace the traditional mechanical wiper system.
