| 摘 要： | 该文提出一种基于CPLD的小车自动寻迹系统。该系统采用红外线发射接收对管对白色（或黑色）地面的黑色（或白色）轨迹进行检测，并将检测结果送给CPLD进行判断和处理，由CPLD产生控制步进电机行进的控制信号。实践表明，该方法设计的智能小车能够根据给定路径进行自动平稳的跟踪行走。

| Abstract: | The article presents a car auto-trailing system based on CPLD. Infrared transmitters/receivers are used to detect the black track on white ground （or white track on black ground） in the system. And the detecting results are sent to the CPLD and judged and dealt with by it, and then, the CPLD generates the control signals for the step motor travelling. The applieiton practice shows that the smart car could move steadily on the given path and search for the track automatically. |
