Embodiment Construction

[0056]The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] At present, the parking space identification steps sampled by the automatic parking system cannot accurately identify the slope and fixed point of the parking space, so that the control and positioning of the automatic parking vehicle cannot be 100% accurate, and there may be accumulated errors in the parking process, resulting in During the parking process, the tracking accumulative error of the initially identified parking space is relatively large, whi...

Abstract

The invention relates to the technical field of automatic parking systems, in particular to a parking space angle recognition method and an automatic parking method, and the method comprises the following steps: scanning an obstacle, close to one side area of a vehicle, of a parking space entrance in real time in a reverse parking process, and obtaining the coordinate value of the obstacle; obtaining a discrete point set of a plurality of coordinate values; fitting the discrete point set into a straight line through a least square method; and calculating the slope of the obstacle according tothe straight line formed by fitting, wherein the slope is the parking space angle. The invention aims to provide the parking space angle identification method and the automatic parking method. By adopting the method provided by the invention, the technical problem that a current automatic parking system cannot accurately identify a parking space is solved.

Description

technical field [0001] The invention relates to the technical field of automatic parking systems, in particular to a parking angle recognition method and an automatic parking method. [0002] technical background [0003] With the increase of car ownership, parking difficulty has become a common phenomenon, and the narrow space of parking spaces leads to frequent accidents during parking. The emergence of automatic parking system can effectively avoid safety accidents during parking. Therefore, the automatic parking system has become a research hotspot of major enterprises and research institutions at home and abroad. [0004] The automatic parking system has been gradually applied to some vehicles as a high-end configuration. from figure 1 It can be seen that the currently commonly used automatic parking system mainly includes the following three parts: a parking space recognition system, a path planning system, and a parking control system. The automatic parking process...
