研究了汽车自动泊车系统,完成了模糊控制自动垂直泊车系统的设计。在分析了自动泊车系统组成的基础上,从垂直泊车的实际情况出发,完成了基于FPGA的模糊控制自动泊车系统总体结构的构建。泊车系统采用FPGA作为核心处理器,控制算法采用模糊PID算法,对周围环境数据的采集通过超声波传感器的使用完成,再通过PID模糊控制器完成信息的分析处理过程。仿真测试结果表明模型车航向角范围在-34°～34°之间,该系统完成了自主无碰撞泊车过程,具有较高的参考价值。

This paper mainly studies the automatic parking system, completes the design of an automatic vertical parking system based on fuzzy control. Based on the analysis of the composition of the automatic parking system and the actual situation of the vertical parking system, this paper completes the construction of the overall structure of the fuzzy control automatic parking system based on FPGA. Using the FPGA as the core processor, the control adopts the fuzzy PID algorithm. The data acquisition of the surrounding environment is completed by using the ultrasonic sensor, and then the analysis and processing of the information are completed by the PID fuzzy controller. The simulation test results show when the heading angle is between-34° to 34°, the system can completed its autonomy saftly. Parking non-collision process has been designed, and has high reference value.
