Design of Intelligent Vehicle Control System Based on STC89C52 Single Chip Microcomputer

该文采用STC89C52单片机为核心控制单元,通过控制2个L298N电机驱动模块控制四个电机的正反转,实现智能车的差速控制;利用4个红外光电传感器以阶梯状均匀分布模式布置在智能车前部,用于采集路面的信息以实现循迹功能。该文详细论述了智能车控制系统的具体设计方案,以及智能车控制系统的软硬件实现过程,并且具体分析了智能车的车身结构对其速度和转向的影响。实验证明,该系统能很好地满足智能车对路径的识别和抗干扰能力较强的要求,智能车速度调节响应时间快,稳态误差小,具有较好的动态性能和良好的鲁棒性[1-4]。

This article introduces the autonomous tracing intelligent car design.Smart car takes the STC89C52 single-chip micro computer as the core control unit,single-chip microcomputer controls two L298N motor driver module to change the intelligent car’s four motors driving or reversing,then realize differential control.Intelligent vehicle use four infrared electric sensors which distributed in front of the intelligent car horizontally.the sensors are used for collecting the information of the road to realize the tracing function.This paper summarizes the specific subject of the operating system and the operations of the system’s software and hardware,analyses the influence of the whole structure for the speed and the turning of the car.Experiments indicate the sys tem is best suit for the intelligent car right path recognition performance and anti-interference ability request,speed regulation fast response time,steady state error is small,has fantastic dynamic performance and stronger robustness.
