Parking Route Control for Auto Parking From Shifted Start Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems cannot automatically park a vehicle at a registered parking space if the vehicle stops at a different position from where the parking space information was initially acquired.
Innovation Solution
A parking assistance apparatus with an electronic control unit that detects feature points from images and memorizes them as start and middle points, allowing the vehicle to be automatically parked by setting a target or reference moving route based on stored route information, enabling automatic parking even when the vehicle stops at a different position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system requires the vehicle to stop at the exact position where parking space information was acquired, then the automatic parking control can be executed with simple position matching, but the system cannot accommodate vehicles stopping at different positions
Solution Approach 1:
The system performs preliminary acquisition and storage of parking space information (boundary positions, route information) when the vehicle is manually parked at the space. This pre-stored information enables the system to later execute automatic parking even when the vehicle stops at different positions, as the reference data is already available for comparison and route reconstruction
Solution Approach 2:
The system creates a copy of the parking space information and route data during manual parking, storing it as reference information. This copied data allows the automatic parking control to function without requiring the vehicle to be at the exact same position, as the system can compare current position against the stored reference copy
2Manufacturing precision
If the system stores detailed route information for precise automatic parking, then parking accuracy is improved, but the calculation load on the control unit increases
Solution Approach 1:
The system extracts and stores only the essential route information (key positional data, boundary information) during manual parking, rather than storing complete trajectory data. This extracted minimal sufficient information maintains parking accuracy while significantly reducing the calculation load and memory requirements during automatic parking execution
Solution Approach 2:
The system stores route information that is sufficient for accurate parking execution without capturing every detail of the manual parking trajectory. This partial information approach provides adequate precision for automatic parking while avoiding the excessive calculation burden of processing complete route data
3Ease of operation
If the system allows automatic parking to be requested during manual parking, then user flexibility is improved, but the control logic becomes more complex
Solution Approach 1:
The system allows dynamic switching between manual and automatic parking modes during the parking process. The control logic can transition from manual control to automatic execution based on user input, with the ability to cancel or initiate automatic parking at appropriate moments. This dynamic flexibility is enabled by the pre-stored reference information that remains available regardless of mode

AI summary
A parking assistance apparatus (10) sets a reference moving route, based on route information when a feature point corresponding to a registered start feature point is detected, automatically parking an own vehicle (100) at a parking space (200) is not requested, and a driver of the own vehicle (100) starts manually parking the own vehicle (100) at the parking space (200). After the driver starts manually parking the own vehicle (100) at the parking space (200), the parking assistance apparatus (10) executes an automatic parking control when automatically parking the own vehicle (100) at the parking space (200) is requested, and a positional relationship between the own vehicle (100) and the reference moving route satisfies a predetermined condition.
