基于飞思卡尔单片机的智能电动小车设计

针对交通堵塞、 交通事故频发等问题, 设计了一种智能电动小车。该设计采用MC9S12XS128单片机作为主控芯片, 结合摄像头、 无线模块等功能模块组成智能电动小车。主控芯片对摄像头采集的赛道信息进行分析处理, 采用PID（Proportion Integration Differentiation）控制策略驱动电机运转, 使智能电动小车能在跑道上完成单轨迹前行、 双轨迹中心线中的自动行驶和避障等动作。利用无线模块实现智能电动小车与目标靶之间的信息交换, 通过智能电动小车对舵机的调整, 完成在行驶过程中将激光光点投射在目标靶中心的实验。打靶成绩较高, 实验结果令人满意。该设计可为智能车辆无人驾驶和信息交互的研究提供参考。

Design of Intelligent Electric Vehicle Based on Freescale Microcontroller

In order to provide more reference for the unmanned vehicle, an intelligent electric vehicle was designed. This intelligent electric vehicle wascomposed of MC9S12XS128 microcontroller as the master chip,camera and wirelessmodule, etc. The master chip analyzed the information collected fromcamera and drove the motor running with PID（Proportion Integration Differentiation） control strategy, which made the intelligent electric vehicle automatically run on the single track and the medium line of the double track, and automatically avoid obstacle. The intelligent electric vehicle exchanged the information with the target by using wireless module, which made the intelligent electric vehicle cast laser spot on the center of the target in the course of drivingby adjusting the steering gear. Shooting scores was high, and the result of theexperiment was satisfactory.
