Vehicle and automatic parking method, system

Abstract

The invention proposes a vehicle and automatic parking method and system. The automatic parking method includes the following steps: collecting surrounding obstacle information and free parking space information through ultrasonic radar, and collecting line parking space information of the free parking space through a camera; obtaining Vehicle position information and vehicle status information; generate multiple planned trajectories based on surrounding obstacle information, vehicle location information, free parking space information, free parking space line parking space information and vehicle status information, and provide multiple planned trajectories to the user; Receive the target planning trajectory selected by the user and perform automatic parking according to the target planning trajectory. This automatic parking method collects information simultaneously through ultrasonic radar and panoramic cameras, and can not only detect obstacles but also parking space lines, solving the limitations and low detection accuracy of automatic parking in the existing technology. problems and improve the automation of parking.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an automatic parking method, an automatic parking system and a vehicle. Background technique [0002] With the rapid development of vehicle technology and the remarkable improvement of people's living standards, vehicles have become a common means of transportation. However, with the increase in the number of vehicles, the parking problem has become a difficult problem for vehicle users. On the one hand, the parking spaces are becoming more and more tense, and users need to spend a lot of time and energy when parking; on the other hand, some inexperienced users are likely to have vehicle scratching accidents during parking, resulting in economic losses . [0003] In order to achieve effective parking, ultrasonic radar is currently used in related technologies for parking space detection.

AI Technical Summary

Problems solved by technology

However, as the number of vehicles increases, parking issues become a challenge for vehicle users

On the one hand, the parking spaces are becoming more and more tense, and users need to spend a lot of time and energy when parking; on the other hand, some inexperienced users are likely to have vehicle scratching accidents during parking, resulting in economic losses

[0003] In order to achieve effective parking, ultrasonic radar is currently used in related technologies for parking space detection. However, this method has limited requirements for parking space detection. It cannot detect parking space lines, but can only detect obstacles, and the detection accuracy of moving obstacles is limited.

Therefore, the parking method has limitations, low degree of automation, and low accuracy
