说明：  智能小车由单片机STM32为主控制核心，设计了小车的正常运行及超车，路面黑线检测采用红外探测，车速和距离检测使用了霍尔传感器，系统主要由单片机驱动模块，无线通信模块，红外检测，霍尔传感模块等模块组成
(Smart car is dominated by the microcontroller STM32 control the core design of the normal operation of the car and overtaking, the pavement black line detection using infrared detection, speed and distance detection using a Hall sensor system mainly consists of single-chip driver module, wireless communication module, infrared detection , the Hall sensor module and other modules)
