Parking Reference Control for Demarcated and Undemarcated Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance technologies fail to automatically park a vehicle at an appropriate location within different types of parking regions, whether demarcated by boundary lines or not, as they do not account for the specific characteristics of each type of region.
Innovation Solution
A parking assistance device with a recognition part to acquire surroundings information, a maneuver controller for parking, a maintain stop position controller, a determination part to identify the type of parking region, and a decision part to set a parking reference location based on the region type, using cameras and sonars to determine the optimal parking position within demarcated or undemarcated areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single parking reference location method is used for all parking regions, then the device complexity is reduced, but the adaptability to different parking region types deteriorates
Solution Approach 1:
The system applies different parking reference location determination methods based on the specific type of parking region detected. For demarcated parking regions, one method is used (based on boundary lines), while for undemarcated regions, a different method is used (based on other parked vehicles). This local differentiation allows the system to adapt to various parking scenarios without requiring a completely different system for each case.
Solution Approach 2:
The system dynamically selects the appropriate parking reference location determination method based on real-time detection of parking region characteristics. The determination part identifies whether the region is demarcated or undemarcated, and the decision part switches between different calculation methods accordingly. This dynamic adaptation enables versatility while maintaining a unified system architecture.
2Ease of operation
If automatic parking is implemented without considering parking region type, then the ease of operation is improved, but the reliability of parking accuracy deteriorates
Solution Approach 1:
The system incorporates feedback through the determination part that analyzes parking region characteristics (demarcated vs. undemarcated) and uses this information to adjust the parking reference location calculation. This feedback loop ensures that the most appropriate method is selected based on actual conditions, improving parking accuracy while maintaining automatic operation.
Solution Approach 2:
Before executing the parking maneuver, the system performs preliminary detection and classification of the parking region type. The determination part identifies the region characteristics in advance, and the decision part pre-calculates the appropriate reference location method. This preliminary action ensures accurate parking without requiring manual intervention during the actual parking process.
3Ease of operation
If parking reference location is set without considering boundary lines, then the ease of operation is improved, but the manufacturing precision of parking position deteriorates
Solution Approach 1:
The system applies different reference location determination methods based on the local characteristics of the parking region. When boundary lines are present (demarcated regions), the system uses these lines as the primary reference. When boundary lines are absent (undemarcated regions), the system alternatively uses other parked vehicles as reference. This local adaptation ensures precise parking positioning tailored to each scenario.
Solution Approach 2:
The decision part acts as an intermediary that selects between different reference sources (boundary lines or other vehicles) based on the parking region type determined by the determination part. This intermediary function ensures that the most suitable reference is used in each context, maintaining high parking precision without complicating the overall operation.
