Device and method for finding a parking space based on a large parking lot scene

Abstract

The invention discloses a device and method for finding a parking space based on a scene of a large parking lot. The device includes: an optimal parking space decision unit for determining the optimal parking space and a suboptimal parking space; a parking space state judging unit for Judging whether to pass through an idle parking space and the usage status of the optimal parking space before reaching the optimal parking space; the mode selection unit is used to continue driving towards the optimal parking space according to the set mode when the parking space judging unit determines that the parking space has passed through an idle parking space The target parking space decision-making unit is used to determine that the optimal parking space is in an idle state at the parking space state judging unit, then the optimal parking space is used as the target parking space; the parking space state judging unit determines that the optimal parking space is in an occupied state, Then continue to judge whether the distance between the current position of the vehicle and the sub-optimal parking space and the nearest free parking space passed by during driving is greater than the set distance value, if so, the sub-optimal parking space will be used as the target parking space; parking space.

Description

technical field [0001] The invention relates to the technical field of intelligent vehicle behavior decision-making, in particular to a decision-making device and method for intelligent vehicles to search for parking spaces based on a large parking lot scene. Background technique [0002] In the era of manned cars, it is difficult for drivers to find a satisfactory parking space in a large parking lot. With the continuous development of intelligent vehicle technology, intelligent parking systems emerge as the times require. The intelligent parking system includes two parts: the first part is the parking space information assistance category: when needed, it helps the owner to find a parking space, even provides multiple optional parking spaces, and guides the car to the appropriate parking space. The second part is the parking assistance category: including reversing radar, semi-automatic parking assistance, remote control / automatic parking, and valet parking, which are base...

AI Technical Summary

Problems solved by technology

However, at this stage, most of the parking lots are ordinary parking lots, which cannot provide detailed parking space information for the intelligent parking system.
