智能避障小车的设计与实现
摘 要
随着现代交通的发展及科学技术的提高,私家小车的数量也在逐步增加,道路的拥挤与交通事故的频繁发生,这严重的影响了人的生命安全。为了解决在两车距离问题上尽量避免或减少交通事故的发生,本课题提出了采用超声波传感器技术研究分析智能小车的避障系统。
本设计主要由系统主控制部分、驱动单元部分、小车躲避障碍物单元设计、显示单元设计、检测电路设计与电机控制电路设计等组成。用超声波传感器模块实时监测路面状况信息,作为障碍物的检测信号读入,当检测距离小于设定值时,立刻执行避障及报警程序,实现小车的自动行驶和避障功能。调试结果表明,本设计完成了小车的自动行驶、超声波避障及实时显示等功能,达到了预设的要求。

ABSTRACT
With the development of modern transportation and the improvement of science andtechnology, the number of private cars is gradually increasing,road congestion and frequent traffic accidents, which seriously affect the safety of people's lives. In order to solve the problem of the distance between two vehicles and avoid or reduce theoccurrence of traffic accidents as far as possible,this paper proposes to use ultrasonic sensor technology to study and analyze the obstacle avoidance system of intelligent car.
The design is mainly composed of the main control part of the system,the driving unit, the car avoiding obstacles unit design,the display unit design, the detection circuit design and the motor control circuit design. When the detection distance is less than the set value,the obstacle avoidance program is executed immediately to realize the automatic driving and obstacle avoidance function of the car. The debugging results show that the design has completed the car's automatic driving,ultrasonic obstacle avoidance and real-time display and other functions, reaching the preset requirements.
