Wireless Power Parking Assist Coil Gap Region Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assist systems for wireless power supply do not effectively determine the power supply possibility based on the gap between the ground-side and vehicle-side coil units, limiting the power suppliable range and convenience in parking.
Innovation Solution
The system determines the vehicle's position relative to predefined power suppliable regions based on the gap between the coil units, using distance measuring units and calculators to assess the possibility of power supply, and displays the results to the user, thereby increasing the power supply range and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power supply possibility is determined without considering the gap between coil units, then the determination process is simple, but the power suppliable region is limited and parking convenience is poor
Solution Approach 1:
The system pre-calculates and stores power suppliable regions for multiple gap conditions before actual parking operation. The processor stores a plurality of power suppliable regions corresponding to different gap conditions, so when parking assistance is needed, the system only needs to compare the current vehicle position against these pre-computed regions, avoiding complex real-time calculations while expanding the power suppliable region
Solution Approach 2:
The system dynamically adapts the power supply determination by considering multiple gap conditions rather than using a fixed threshold. By determining power supply possibility based on whether the vehicle position falls within power suppliable regions that account for different gap variations, the system flexibly adjusts to actual parking scenarios, improving both convenience and accuracy
2Adaptability or versatility
If a fixed power supply threshold is used, then the control logic is simple, but the power suppliable range is limited
Solution Approach 1:
The system changes the determination parameter from a single fixed threshold to multiple power suppliable regions corresponding to different gap conditions. By storing and comparing against multiple regions that represent different gap scenarios, the system expands the power suppliable range while maintaining manageable complexity through structured data organization
Solution Approach 2:
The power supply determination space is segmented into multiple discrete power suppliable regions, each corresponding to a specific gap condition. This segmentation allows the system to handle complex multi-condition logic by dividing it into manageable regional comparisons, making the determination process systematic and scalable

AI summary
A parking assist system is used in a wireless power supply system which performs wireless power supply between a ground-side coil unit and a vehicle-side coil unit. The parking assist system determines a position of a vehicle relative to each of a first region in which the power supply is possible when a gap between the vehicle-side coil unit and the ground-side coil unit is maximum and a second region in which the power supply is possible when the gap is minimum. The parking assist system determines possibility of the power supply, based on a result of the determination on the vehicle position, and displays a result of the determination on the possibility of the power supply, for an occupant of the vehicle.
