V2X-based control system and method of underground parking valet parking

Abstract

The invention provides a V2X-based control system and method of underground parking valet parking. The control system comprises a vehicle information collecting unit, a vehicle control unit, a parkinglot information collecting unit and a parking lot central processing unit; the parking lot information collecting unit and the parking lot central processing unit carry out information transmission in a wired mode; and the vehicle information collecting unit, the vehicle control unit and the parking lot central processing unit carry out the information transmission in a wireless communication mode. According to the V2X-based control system and method of the underground parking valet parking, sizes of spare parking spaces are accurately calculated according to the information of parked vehicles around the spare parking spaces, available parking spaces are allocated according to length sizes and width sizes of waiting vehicles, the time spent by vehicles searching for parking spaces is reduced, the parking lot resources are used rationally, and the parking efficiency is effectively improved; and by the information fusion of the parked vehicles, the waiting vehicles and parking lot cameras, precise positions of the waiting vehicles in the parking lot are obtained, and the parking accuracy is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of unmanned driving, and in particular relates to a V2X-based valet parking control system and method in an underground parking lot. Background technique [0002] With the advancement of science and technology, the number of cars in my country continues to grow, and urban car owners are plagued by problems such as insufficient parking spaces, parking difficulties, and queues for payment. The application of automated valet parking technology can bring more solutions to parking challenges, saving car owners time and effort. Users only need to drive the vehicle to the designated drop-off area of ​​the parking lot, and start the automatic valet parking program after getting off the car, allowing the vehicle to complete automatic parking without manual operation by connecting with the intelligent infrastructure installed in the parking lot . [0003] V2X is Vehicle to X, where X stands for roadside infrastructu...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the present invention aims to propose a V2X-based underground parking lot valet parking control system to solve the problem that the vehicle spends a lot of time in the library search phase and the underground parking lot has weak or lost GPS signals due to building occlusion. This leads to the problems of low efficiency, low precision and even parking failure of the valet parking system.
