Parking Path Correction for Wireless EV Charging Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance technologies fail to efficiently align electric vehicles with contactless power supply devices during home zone parking, leading to suboptimal charging efficiency and requiring repeated driver intervention to find the ideal parking position.
Innovation Solution
A parking assistance device equipped with a processor and memory that records a vehicle's travel path during teacher traveling, acquires information about the contactless power supply device's position, corrects the travel path to minimize the distance between the vehicle's power receiving device and the charging coil, and executes automated parking based on the corrected path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If home zone parking is performed without correcting the travel path based on contactless power supply device position, then the parking process is simple, but the alignment between vehicle and power supply device is poor
Solution Approach 1:
The system performs preliminary correction of the travel path by acquiring contactless power supply device position information and adjusting the recorded path before automated parking execution. This preliminary action ensures precise alignment between the vehicle and power supply device without requiring complex real-time adjustment mechanisms during parking.
2Manufacturing precision
If driver performs trial-and-error parking to find ideal position, then parking position can be optimized, but time is wasted and driver intervention is required
Solution Approach 1:
The automated parking system performs self-service by automatically correcting the travel path based on contactless power supply device position information. The system independently optimizes the parking position without requiring driver trial-and-error intervention, thereby achieving precise alignment while eliminating time waste and manual intervention.
3Manufacturing precision
If extensive sensor networks are used to achieve precise alignment, then alignment precision improves, but system complexity and cost increase
Solution Approach 1:
The system extracts and utilizes existing contactless power supply device position information that is already available in the environment, rather than deploying extensive sensor networks to detect this information. This approach achieves precise alignment by leveraging external data sources, thereby simplifying the vehicle's sensor requirements and reducing system complexity.
