基于激光传感器的智能车设计

摘要

This article introduces the design of a intelligent vehicle and scheme of the hardware and software based on MC9S12XS128 of Freescale.The track information acquisition is done by laser sensor.After the data being treated by the controller PWM signal is generated to control the movements of motors.The vehicle velocity is detected by photoelectric encoder and feedback to the controller forming close-loop control for better control effect.%以飞思卡尔半导体公司的MC9S12XS128单片机为核心,介绍了智能车的设计思想,硬件及软件设计方案。单片机通过激光传感器采集路径信息,处理后产生PWM信号控制电机转动,采用光电编码器做速度检测,从而实现闭环控制。
