In order to realize the unmanned automatic parking, a parking plan which combines the parking path planning and the control strategy is designed. In the scheme, the parking system is mainly composed of 3 modules, which are the information acquisition system of the vehicle, the real-time data processing system, and the vehicle strategy control system. Through the rational installation of ultrasonic sensor group, monitor the environment information around the car in real-time, and timely feedback the real-time information of the vehicle. Through experimental verification and experimental data collation, the experimental results show that the scheme can realize the automatic perception of the vehicle environment, automatically plan the driving route, control the car to arrive at the predetermined parking location or predetermined target, and initially realize automatic parking.
