超声波传感器实现垂直泊车

自动泊车系统主体是一辆模型小车,具有前轮转向后轮驱动的能力,电源为蓄电池,实验平台实现小车的运动控制,运用超声波传感器检测小车前方障碍物以及离目标车位的距离来实现小车自动倒库功能,系统分为超声波测距、倒车控制、车位检测、人性化的界面显示,运用对多个传感器实时测量值边缘滤波处理和中值滤波处理的结果显示车辆与障碍物的位置,通过模糊控制理论,计算前轮的转向角度及车辆运行速度,最后可以自动地完成泊车操作。

Ultrasonic Sensors for Vertical Parking

The automatic parking system presents a model car with rear-wheel drive and front-wheel steering, battery-powered and controlled by experiment platform. Using ultrasonic sensors, the distance between the target parking lot and the obstacles in front of the car can be detected, and automatic library function can be achieved. The system consists of ultrasonic ranging, reverse control, parking space detection, and humanized interface. The location of the vehicle and the obstacles can be shown according to the results of edge filter and median filter processing for real-time measurements on multiple sensors. Through the fuzzy control theory, wheel steering Angle and vehicle speed will be calculated, and the parking operation can be automatically completed.
