Abstract

The invention provides a full-automatic parking method and system. The full-automatic parking method comprises the steps of acquiring space parking space data and obstacle data recognized by an ultrasonic radar and look-around parking space data and obstacle data recognized by a fisheye camera; performing fusion based on a data fusion algorithm to obtain parking space fusion data and obstacle space fusion data; according to a free track planning algorithm, carrying out planning in combination with the parking space fusion data and the obstacle space fusion data to obtain a parking track; and acquiring moving position information of a current vehicle, and making the vehicle run along the parking trajectory in real time based on a high-precision positioning algorithm and a high-precision track tracking algorithm. In the scheme, the parking track is determined by calculating the parking space fusion data and the obstacle space fusion data obtained by fusion by using the free track planning algorithm. And the vehicle is controlled to run along the parking track by using the high-precision positioning algorithm and the high-precision track tracking algorithm. Precision of parking spacerecognition and automatic parking control is improved so that the method and the system adapt to more parking scenes.

Description

technical field [0001] The invention relates to the technical field of automatic parking, in particular to a fully automatic parking method and system. Background technique [0002] At present, existing vehicles usually use ultrasonic or fisheye cameras, combined with a fully automatic parking domain controller to realize automatic parking. [0003] In the existing technology, limited by the recognition limitations of ultrasonic and fisheye cameras, ultrasonic or fisheye cameras are used to identify parking spaces, but the recognition accuracy is not high, and the trajectory algorithm is intelligently applied to limited scenarios. However, in the vehicle parking control, the prior art usually adopts the PID control mode, and the control precision is low. [0004] To sum up, the existing automatic parking methods have the problems of few adaptable scenarios, low recognition accuracy and low automatic parking control accuracy. Contents of the invention [0005] In view of ...
