基于飞思卡尔S12单片机的智能车系统设计与实现

Intelligent vehicle system design and implementation based on Freescale S12 microcomputer

以第八届全国大学生飞思卡尔智能汽车比赛为背景,介绍了以飞思卡尔S12单片机作为核心控制单元,通过摄像头采集赛道信息,利用PID算法控制舵机的响应速度,闭环控制马达速度,实现智能车在专门赛道上自主循迹行驶.重点阐述了硬件和软件的实现方法.实践证明,该智能车设计方案有效、可行.

In the context of the eighth ＂Freescale＂ Cup National University Intelligent Vehicle Tournament, Freescale S12 microcomputer is chosen to be the core control unit. Camera captures the track information. PID algorithm is used to control steer angle and motor speed closed -loop. Intelligent vehicle can autonomous drive following the path on the special track. This paper focuses on the implementation of hardware and software. Prac- tice has proved that the intelligent vehicle design is effective and feasible.
