Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking space determining techniques require a vehicle to approach a parking space to detect availability, limiting the detection of all available spaces and preventing the identification of better options.
Innovation Solution
A system comprising a parking space information module, an object analysis module, and a processing module that uses parking lot map data and sensing devices like LiDAR to determine available parking spaces by analyzing spatial relationships and evaluating scores in real-time, allowing the vehicle to identify suitable spaces before approaching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If distance sensing method or image identifying method is used, then parking space can be detected, but the vehicle must approach the parking space to determine availability
Solution Approach 1:
The patent applies preliminary action by using LiDAR to perform long-range detection of parking spaces before the vehicle approaches them. The system identifies and evaluates multiple candidate parking spaces in advance, allowing the vehicle to navigate directly to the selected space rather than searching sequentially, thus reducing the time loss while maintaining detection accuracy.
2Reliability
If vehicle approaches parking space to detect availability, then detection can be performed, but not all available parking spaces can be determined
Solution Approach 1:
The patent transitions from two-dimensional image-based detection to three-dimensional spatial detection using LiDAR. This dimensional change enables the system to detect parking spaces at various distances and angles simultaneously, identifying multiple available spaces in the environment rather than requiring close proximity to individual spaces, thus increasing the number of detectable parking spaces while maintaining reliability.
3Ease of operation
If conventional detection methods are used, then nearby parking spaces can be identified, but better available parking spaces cannot be found
Solution Approach 1:
The patent implements feedback by continuously evaluating detected parking spaces using multiple criteria (distance, occupancy status, accessibility) and updating the selection based on this feedback. The system compares candidate spaces and adjusts the choice to identify the optimal parking space, ensuring that information about better options is not lost and that the best available space is selected.

AI summary
A system and a method for determining a parking space are provided. The method includes: obtaining parking space information within a range where a vehicle is located, the parking space information including parking lot map data; analyzing an object in individual parking space in the parking space information and generating object information of the object of the individual parking space; and using the object information and the parking space information to calculate a spatial relationship between the object in the individual parking space and a parking space where the object is located, and determining that the parking space is an available parking space if the spatial relationship satisfies vehicle body information of the vehicle. Therefore, the vehicle can determine an available parking space before passing it, and can further choose a better parking space.
