Problems solved by technology

[0003] There are still a lot of defects in the existing APA system. For example, the selection range of the initial parking configuration is small, the vehicle must be driven to a fixed position, and the vehicle yaw angle must be within a certain range before parking can be started.

Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the embodiments given in the accompanying drawings.

[0041] A method for constructing a three-dimensional feasible starting parking space based on area superposition proposed in this embodiment uses the information of vehicle body size, current position and orientation of the vehicle, and parking space size. Taking the C-type vertical parking algorithm as an example, for different parking initial yaw angles θ, the corresponding feasible parking initial area is calculated, and then the parking initial area corresponding to each parking initial yaw angle θ is calculated. The areas are superimposed on each other, and finally the three-dimensional feasible parking starting space reference is obtained figure 1 As shown, this embodiment mainly includes the following steps:

[0042] Step 1, determine the position of the parking target point and the corresponding yaw angle;

[0043] Step 2: C...

Abstract

The invention discloses a method for constructing a three-dimensional feasible parking starting space based on area superposition. The three-dimensional space includes the abscissa, ordinate and yaw angle of the starting point of the vehicle. The three-dimensional feasible parking initial space is obtained by solving the parking initial area corresponding to each parking initial yaw angle and the superposition of the parking initial area. The method expands the selection of the initial parking space, and improves the feasibility, flexibility and efficiency of the entire parking process.

Description

technical field [0001] The invention relates to the technical field of intelligent networked vehicles, in particular to a method for constructing a three-dimensional feasible parking starting space based on area superposition. Background technique [0002] With the progress of society and the improvement of per capita consumption level, the average annual car ownership in my country has increased year by year, which makes the insufficient parking space more tense. In addition, with the continuous development of science and technology, the times have put forward new requirements for automobiles, and the intelligentization of automobiles has become an inevitable trend. To solve the problem of difficult parking, more and more car manufacturers have equipped their cars with Automated Parking Assist (APA) to help drivers find and park a parking space. [0003] There are still a lot of defects in the existing APA system, such as the selection range of the initial parking configur...
