Parking Assistance Device Occupant-Validated Environment Map Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance methods may store inappropriate surrounding situations during autonomous parking, leading to inaccurate environment maps and potential misalignment of parking positions.
Innovation Solution
A parking assistance method and device that detects the surrounding situation at a parking target position, presents it to the occupant, and stores it only when deemed appropriate by the occupant, using a combination of sensors and a control device to generate and validate environment maps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If surrounding situation is detected and stored automatically during parking, then productivity is improved, but reliability deteriorates due to storage of inappropriate situations
Solution Approach 1:
The system presents the detected surrounding situation to the occupant and receives feedback on whether it is appropriate. This feedback mechanism allows the system to distinguish between appropriate and inappropriate surrounding situations, ensuring that only valid data is stored for future autonomous parking operations.
Solution Approach 2:
The system performs preliminary detection and presentation of the surrounding situation before final storage. By showing the detected situation to the occupant in advance and obtaining confirmation, the system ensures data quality before committing it to storage, preventing inappropriate data from being saved.
2Productivity
If automatic storage of detected surrounding situation is implemented, then productivity is improved, but manufacturing precision deteriorates due to inaccurate environment maps
Solution Approach 1:
The occupant's confirmation serves as a quality control checkpoint, ensuring that only accurately detected surrounding situations are stored. This feedback loop prevents inaccurate environment map data from being generated, maintaining high precision in the stored information.
Solution Approach 2:
The system combines automatic detection with human verification, where the occupant acts as a final validator. This hybrid approach leverages both automated efficiency and human judgment to ensure high accuracy in the stored surrounding situation data.
3Device complexity
If surrounding situation is stored without verification, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The system introduces a simple feedback mechanism where the occupant confirms or rejects the detected surrounding situation. This adds minimal complexity to the system structure while dramatically improving measurement precision by filtering out inaccurate detections.
Solution Approach 2:
The occupant acts as an intermediary between the automatic detection system and the storage function. This human mediator validates the detected data, ensuring high measurement precision without requiring complex automated verification systems.

AI summary
Provided is a parking assistance method capable of storing surrounding situation of a parking target position appropriate to be referred to during autonomous parking. The parking assistance method of storing the surrounding situation of the parking target position when parking at the parking target position and executing the autonomous parking using the stored surrounding situation, includes a step of detecting the surrounding situation; a step of indicating the detected surrounding situation; a step of receiving a determination of whether the indicated surrounding situation are appropriate input by an occupant; and a step of storing the surrounding situation when the determination of appropriateness is input by the occupant.
