Abstract

The invention provides a parking track correcting method. Usually in a parking guide stage, control errors exist due to various factors such as a control system and an execution mechanism in the vehicle travel process, and inevitably, an actual travel route travelled by a vehicle controlled by the system deviates from a parking track set by the system. By the adoption of the parking track correcting method, the actual travel route of the vehicle and the parking track set by the system in advance are compared in real time to obtain the difference, when the difference is large, the parking track of the vehicle is planned again according to the actual position of the vehicle, the condition of surround obstacles and the position of a parking place, and therefore the parking process of the vehicle can be finished without collisions according to the new parking track.

Description

technical field [0001] The invention relates to the field of ultrasonic automatic parking systems, and more specifically relates to a method for correcting a predetermined parking trajectory by an automatic parking system during the process of parking a car in place. Background technique [0002] With the development of science and technology, more and more automation methods have begun to integrate into our lives today. Today, as people have higher and higher requirements for their own quality of life, in such a fashionable era, more and more people need a car that can assist them in parking. [0003] It is precisely because of this need that more technicians have begun to study how the car can accurately find its own position like a human being. Therefore, a more convenient, safe and reliable parking method has become the pursuit of many car owners and R&D personnel. [0004] In order to meet the requirements of safety and reliability, to meet such requirements, the traj...
