Parking Support Device Re-detection for Missed Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assist systems fail to detect available parking spaces when the initial detection process does not identify them as such, even though they are actually available for use.
Innovation Solution
The system re-detects a first parking space when a second space is selected by the driver, adjusting detection criteria to ensure accurate identification of available spaces, allowing for parking in spaces initially missed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system uses initial detection criteria to identify parking spaces, then the detection process is efficient and quick, but available parking spaces may be missed and not identified as usable
Solution Approach 1:
The system performs a preliminary detection process to identify parking spaces that meet basic criteria, then performs a secondary re-detection when spaces are selected but not confirmed as available. This preliminary action ensures that potentially available spaces are not initially missed while maintaining efficient initial screening.
Solution Approach 2:
The system changes detection parameters between the initial detection phase and the re-detection phase. During re-detection, the system adjusts detection criteria to be more inclusive or sensitive, allowing spaces that were initially missed to be identified as available for use.
2Reliability
If the system re-detects parking spaces when another space is selected, then more available spaces can be identified, but the processing time and system complexity increase
Solution Approach 1:
The detection process is made dynamic by allowing the system to switch between initial detection mode and re-detection mode based on user interaction. When a parking space is selected but not confirmed as available, the system dynamically initiates re-detection with adjusted parameters, balancing accuracy needs with processing efficiency.
Solution Approach 2:
The system uses feedback from user selection and confirmation actions to trigger re-detection. When the driver selects a parking space and the system determines it is not actually available, this feedback initiates a re-detection process with modified criteria to correctly identify the space as usable.
3Measurement precision
If the system maintains strict detection criteria, then false positives are reduced, but valid parking spaces are incorrectly excluded from available options
Solution Approach 1:
The system performs preliminary detection with strict criteria to filter out clearly unsuitable spaces, then performs re-detection with more flexible criteria when needed. This two-stage approach maintains precision for obvious cases while gaining flexibility to include spaces that may be valid under different interpretation of detection criteria.

AI summary
A method of displaying parking assist information is used in a parking assist apparatus comprising a display and a control device. The control device detects a first parking space that satisfies a predefined parking condition. When information of selecting a second parking space other than the first parking space is input, the control device re-detects a parking space that satisfies the predefined parking condition as the first parking space.
