自动循迹小车在不用人为干预的情况下，可以按照预定轨迹自动行进，该技术在工业上有很高的指导和应用价值。文章介绍的是一种复杂路况下智能循迹小车的设计方案，系统以单片机AT89S51为控制核心，采用高灵敏度的红外传感器采集路面信息，并将信息传到AT89S51，由单片机根据路况信息控制小车的行进方向，并产生PWM波来调整小车的速度，从而实现小车在复杂路况下的平稳循迹。

Automatic tracking car can go without human interfering, this technology is important in industry. This paper propos-es a design of tracking car in complex situation of street, which is consist of AT89S51 as center, infrared rays sensor is used for col-lecting street information, sends information to AT89S51, the MCU controls the movement direction of car according to street information, and changes the speed of car by PWM, all of this promise the car moves stably following the line in complex situa-tion of street.
