摘　　要：文中介绍了一种基于FPGA的智能小车设计方案,系统采用FPGA产生的PWM波调控小车速度,红外线传感器TCRT5000检测路面上的黑色轨迹,并将检测到的信号反馈给控制芯片FPGA,FPGA由采集到的信号发出指令,控制小车电机驱动电路以调整行驶方向,从而使小车能够沿着黑色轨迹自动行驶,同时利用了超声波模块实时的检测前边的障碍物,实现了小车的避障循迹功能。This paper introduces a kind of tracking of obstacle avoidance car design scheme based on FPGA,The system adopts the FPGAgenerated PWM wave control of speed of a car,infrared sensor on the CRT5000 pavement black locus is detected,and the detected signal is fed back to the micro control system FPGA,FPGA form the collected signal issues an instruction to control motor drive circuit of the car to adjust the driving direction so that the car can run along the black path,At the same time using the ultrasonic module real-time detect the obstacles in front of it and realizes the obstacle avoidance car tracking function.
