Embodiment Construction

[0019] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Unless otherwise defined, all terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that commonly used terms should be interpreted to have a meaning consistent with their meaning in the relevant art and this disclosure. This disclosure is to be considered as an example of the invention and is not intended to limit the invention to the particular embodiments.

[0020] This embodiment provides a parking method using ultrasonic radar, which is mainly used to improve the phenomenon of mishandling of the steering wheel during vertical parking, reduce the number of times of parking, and reduce the parking time. The method is realized based on the first ultrasonic radar, the second ultrasonic radar, a control center and a display,...

Abstract

The invention relates to the technical field of automatic parking, in particular to a parking method and system applying an ultrasonic radar, and is mainly used for improving the phenomenon that a steering wheel is mistakenly turned in the vertical parking process and reducing parking time. The method is realized based on a first ultrasonic radar, a second ultrasonic radar, a control center and a display, and comprises the following steps: S1, the first ultrasonic radar detects an approximate parking space; s2, the control center calculates the size of the approximate parking space; s3, the second ultrasonic broadcast radar detects an obstacle space and an idle space in the approximate parking space; s4, the control center calculates the size of an idle space and the size of an obstacle space and calculates a blind area space; s5, the display displays the approximate parking space, the idle space, the obstacle space and the blind area space; and S6, the display updates the idle space, the obstacle space and the blind area space. The probability of collision with obstacles is reduced, the number of times of garage rubbing is reduced, and the parking time is shortened.

Description

technical field [0001] The invention relates to the technical field of automatic parking, in particular to a parking method and system using ultrasonic radar, which is mainly used to improve the phenomenon of mishandling of the steering wheel during vertical parking, reduce the number of rubbing times, and reduce parking time. Background technique [0002] With the improvement of living standards, cars are rapidly popular among the crowd, making parking a more difficult problem. When a vehicle passes through the gap between two obstacles, the data information collected by ultrasonic radar can identify the length of the gap. , to determine whether parking is possible, after determining that the parking conditions are satisfied, determine the vehicle speed and the expected value of the steering wheel angle through the collected distance information, and complete the parking, such as a kind of automatic parking system whose publication number is CN 104401260 B, including informa...
