摘　　要：基于实际的小车模型,使用PIC16F877A单片机、AH3144霍尔传感器等部件,以C语言为软件编程语言,设计实现了一个汽车电控巡航控制模拟系统.首先对系统总体结构进行介绍,然后详细阐述了系统各功能模块的软件设计方案,并对其软件核心控制策略—增量式PID算法进行改进,最后给出了部分程序示例及仿真调试结果.实验结果表明,改进的增量PID算法使系统响应更快,增加了巡航控制的稳定性,整个系统能较好地满足自动巡航的各项功能需求,具有一定的市场应用价值.Based on the actual car simulation system is designed and imp AH3144 and other electronic elements model, an electronic automobile cruise control emented by single chip P1C16F877A, hall sensor with C language as the programming language. Firstly, the whole system structure is introduced. Then, the software design scheme of each functional module is explained, and the core software control strategy-the incremental PID algorithm is improved. Finally, some program examples and result of simulation debugging are given. The result shows that the improved incremental PID algorithm makes the system response faster and increases the stability of cruise control. The whole system can satisfy all requirements of cruise control well, and has a certain value in the market.
