摘要

智能汽车广泛应用于各个行业,其运行状况对行业的安全生产至关重要。本文设计了一套基于STM32F103C8T6单片机的智能小车控制系统,并对小车的自动控制进行了研究。本研究选择一个黑色矩形区域,周围有白色边框作为汽车运行的外部环境。在保证汽车不越界的前提下,汽车可以在区域内自动巡航,遇到障碍物时可以避障。首先,建立控制系统的设计思想,完成整车模型的构建;其次,设计硬件系统的总体方案和程序;然后用示波器采集并验证小车在各种工况下的电机脉冲信号和传感器输出信号;最后,在保持汽车一定速度的情况下,对汽车的避障和边线检测进行了多次实车验证。结果表明,该车能较好地完成前进、后退、调速、避障等功能。自动控制系统运行稳定,可靠性高。

Design of Intelligent Car Control System Based on STM32
Smart cars are widely used in various industries, and their operating status is crucial to the production safety of the industry. In this paper, a set of intelligent car control system is designed based on STM32F103C8T6 microcontroller, and the automatic control of the car is studied. The study selects a black rectangular field with white borders around it as the external environment for the car to run. Under the premise of ensuring that the car does not cross the boundary, the car can automatically cruise in the area and avoid obstacles when it encounters them. Firstly, establish the design idea of the control system and complete the construction of the car model; Secondly, design the overall scheme of the hardware system and program; Then use the oscilloscope to collect and verify the motor pulse signals and sensor output signals of the car under various working conditions; Finally, while maintaining a certain speed of the car, several real-vehicle verifications were carried out on the obstacle avoidance and sideline detection of the car. The results show that the car can well complete functions such as forward, backward, speed regulation, and obstacle avoidance. The automatic control system runs stably and has high reliability.
