一种嵌入式巡航控制设计

针对轿车驾驶的安全性和舒适性,设计一种新型巡航控制系统(CCS).在分析了巡航控制系统的基本原理,确定了输入输出信号以后,给出了一种基于三星公司S3C44B0X芯片控制器的嵌入式巡航控制系统设计方案.阐述了其软硬件设计思想和方法,所采用的自适应PI控制,具有反应速度快、系统稳定性好和超调性小等特点.通过计算机仿真表明,所采用的控制策略是可行的,能较好地模拟真实系统.嵌入式巡航控制系统操作简单,可靠性强,易扩展升级,有实际应用价值.

The design of embedded cruise control system

To make driving safer and more comfortable,cruise control system(CCS) is studied.After analyzing the basic principle of cruise control system and ensured I/O signals we give a design scheme of cruise control system based on S3C44B0X of samsung corporation.This paper shows the theory and method of hardware design and the auto-adaptive PI controlling which has quick response,stability,low overmodulation range and other features.Through computer simulation we find the control method is feasible and can simulate the real system.It proves that CCS is simple to operate,of high reliability,easy to extend and upgrade and also has huge value of practical application.
