Solution Overview
Problem
Existing autonomous parking systems lack a reliable method to validate the correct positioning of vehicles for successful autonomous parking maneuvers, particularly in narrow spaces where manual alignment is difficult.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual alignment methods are used for autonomous parking validation, then the validation process becomes complex and time-consuming, but the positioning accuracy is insufficient for narrow parking spaces
Solution Approach 1:
The patent introduces a positioning mat as an intermediary tool between the vehicle and the parking space. The mat contains predefined markings that serve as reference points for both longitudinal and angular positioning. This intermediary device simplifies the validation process by providing visual guides that eliminate complex manual alignment procedures while ensuring high positioning accuracy for autonomous parking validation
Solution Approach 2:
The positioning mat is prepared in advance with pre-calculated markings for various angular offsets (0°, 15°, 30°, 45°, 60°) and longitudinal offsets. These preliminary markings are created based on geometric calculations before the actual validation process, allowing the testing procedure to directly follow the visual guides without performing complex alignment calculations during testing
2Adaptability or versatility
If the parking space dimensions are fixed, then the validation setup is simple, but the system cannot test various parking space sizes
Solution Approach 1:
The positioning mat is divided into multiple removable tiles that can be assembled in different configurations. Each tile contains specific markings, and by rearranging the tiles, the mat can adapt to different parking space dimensions and angular offsets. This segmentation allows the same basic component (tiles) to serve multiple validation scenarios without requiring completely different setups for each parking space size
Solution Approach 2:
The positioning mat is designed as a universal tool that can validate autonomous parking functions across multiple parking space configurations. By incorporating markings for various angular offsets and using removable tiles that can be reconfigured, a single mat design serves multiple validation purposes, eliminating the need for separate validation tools for each parking space dimension
