摘要
介绍了一种基于红外激光管的快速路径识别智能车系统。系统采用Freescale 16位单片机MC9S12DG128做为核心控制器,并用光电传感器采集道路信息以使智能车行驶于既定道路上。通过计算讨论了舵机转臂长度的取值范围,解决了系统的滞后问题;还以偏距计时与当前速度相结合的方式制定出控制策略,使智能车系统能快速平稳地寻迹行驶。
A smart car system based on the technology of infrared laser tube is introduced that can identify the path quickly.The system used freescale 16-bit microcontroller MC9S12DG128 as the core controller and the optical sensor to accept route information.So the smart vehicle could drive on established roads exactly.The range of arm length to deal with the system lags behind problem is calculated.At last,the current rate of time with speed to make out the control strategies is connected which made the intelligent vehicle system trace on the road quickly and smoothly.
