Remote Parking Exit Route Control for Variable Stop Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote parking systems struggle to navigate vehicles to an exit position when the actual parking location differs from the stored position, as they rely solely on movement route information and peripheral environment data from a specific parking position.
Innovation Solution
A control device and method that includes an external environment recognition unit, storage unit, and movement control unit to generate an exit route based on external environment recognition data, route information, and peripheral environment data, allowing flexible movement control to an exit position even when the vehicle is parked at a different location than expected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the system stores only movement route information and peripheral environment information from a specific parking position, then the system complexity is reduced, but the system cannot handle parking at different positions
Solution Approach 1:
The patent segments the stored information into three distinct components: movement route information, peripheral environment information, and landmark information. This segmentation allows the system to store data from any parking position independently, enabling versatility while maintaining manageable data structures for each segment.
Solution Approach 2:
The patent creates a universal data storage structure that can accommodate any parking position. By storing landmark information that is position-independent and using a standardized format for route and environment data, the system achieves multi-functionality to handle various parking locations without requiring position-specific configurations.
2Adaptability or versatility
If the system stores detailed peripheral environment data and landmark information for every possible position, then the adaptability to different parking positions is improved, but the data storage requirements and system complexity increase
Solution Approach 1:
The patent performs preliminary actions by storing only essential landmark information and route structures during the parking process, rather than comprehensively recording all possible environmental data for every position. This preliminary data collection is sufficient for later route generation and vehicle retrieval, reducing overall data storage requirements while maintaining flexibility.
Solution Approach 2:
Instead of storing complete environmental maps for every possible parking position, the patent uses copying of essential route and landmark data structures. The system stores representative data that can be reused and adapted for different positions, reducing redundant data storage while maintaining the ability to generate exit routes from any parked location.
3Speed
If the system generates exit routes based solely on stored route information, then the processing speed is improved, but the system fails when the vehicle is parked at a different position than stored
Solution Approach 1:
The patent implements feedback mechanisms by comparing the vehicle's actual parked position with the stored route information. The system uses detected landmark information and peripheral environment data as feedback to verify and adjust the stored route data, ensuring that exit routes remain accurate even when parking positions vary from the original stored configuration.
Solution Approach 2:
The patent makes the route generation process dynamic by allowing the system to adapt stored route information based on actual parking conditions. Rather than using static pre-defined routes, the system dynamically adjusts route parameters using landmark matching and environment comparison, enabling fast route generation that remains reliable across different parking positions.
Data Source
AI summary
A control device for a moving object includes: an external environment recognition unit; a storage unit configured to store route information; and a movement control unit configured to perform movement control for moving the moving object. The route information includes route data indicating a movement route, stop position data indicating a stop position, and peripheral environment data indicating a feature of a peripheral environment and the stop position. When stop of the moving object at a first stop position identical to the stop position is detected, the movement control unit performs first generation of an exit route based on the route data and the stop position data. When stop of the moving object at a second stop position different from the stop position is detected, the movement control unit performs second generation of an exit route based on the route data and the peripheral environment data.
