Parking Spot Validity Classification via Digital Map Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parking guidance systems fail to efficiently classify the validity of identified parking spots, leading to vehicles driving in vain to invalid spots, as they do not account for no-parking zones and other impermissible areas.
Innovation Solution
A method and device using a distance-based detection system that compares the identified parking spot's position to a digital parking facility map, incorporating curb and delimitation parameters to classify spots as valid or invalid, ensuring only permissible spots are directed to vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a distance-based detection method is used to identify parking spots, then the detection range is extended, but the accuracy of validity classification deteriorates due to inability to distinguish valid from invalid spots
Solution Approach 1:
The patent introduces a digital parking facility map as an intermediary between the distance-based detection method and the validity classification. The map provides additional spatial information that mediates the classification process, allowing the system to accurately distinguish valid from invalid parking spots while maintaining the extended detection range of distance-based methods.
Solution Approach 2:
The patent combines distance-based detection results with digital map data to achieve accurate validity classification. By merging these two information sources, the system overcomes the limitation of distance-based methods alone while preserving their advantage of extended detection range.
2Ease of operation
If all identified parking spots are directed to vehicles without classification, then the system operation is simple, but time is wasted driving to invalid spots
Solution Approach 1:
The patent performs preliminary classification of parking spots before directing vehicles to them. By classifying spots in advance using the digital map, the system eliminates wasted trips to invalid spots while maintaining operational simplicity through automated classification.
3Measurement precision
If position comparison with digital map is performed for each identified spot, then classification accuracy is improved, but device complexity increases
Solution Approach 1:
The patent uses a digital copy of the parking facility map stored in memory, which allows repeated queries and comparisons without requiring access to the original complex mapping infrastructure. This copying approach enables accurate classification while managing system complexity.
