Automatic Parking Route Switching for Occupied Space Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assistance devices struggle with convenience during automatic parking, as they cannot change maps mid-parking, leading to troublesome re-parking when the initial parking position is occupied.
Innovation Solution
A parking assistance device that registers a map with multiple routes from a single parking start position to various parking positions during learning travel, allowing the device to select and switch routes autonomously during automatic parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single map is used for automatic parking, then the device complexity is reduced, but the adaptability to different parking positions deteriorates
Solution Approach 1:
The patent applies multi-functionality by enabling a single map to serve multiple parking positions through the registration of multiple routes. The map management unit registers a map including multiple routes from one parking start position to multiple parking positions, allowing the same map to be used for parking at different locations (e.g., parking positions PA and PB) without requiring separate maps for each position.
Solution Approach 2:
The patent applies dynamics by enabling dynamic route selection during automatic parking. The travel control unit selects an appropriate route from the multiple registered routes based on real-time conditions, such as whether a parking position is occupied. This dynamic switching capability allows the system to adapt to changing parking conditions without changing the map itself.
2Reliability
If the vehicle returns to the start position when the initial parking position is occupied, then reliable parking is ensured, but the loss of time increases
Solution Approach 1:
The patent applies preliminary action by pre-registering multiple alternative routes during the learning phase before actual parking is needed. The map management unit stores multiple routes from the start position to different parking positions in advance. When parking is attempted and the initial position is found to be occupied, the system can immediately switch to a pre-prepared alternative route without needing to return to the start position, thus saving time while ensuring reliable parking completion.
3Adaptability or versatility
If multiple maps are generated for different start positions, then the adaptability to different parking positions is improved, but the device complexity increases
Solution Approach 1:
The patent applies multi-functionality by designing a single map structure that can handle multiple parking positions. Instead of creating separate maps for different start positions, the system registers multiple routes within one map, where each route leads to a different parking position. This universal map approach maintains parking position adaptability while avoiding the complexity of managing multiple separate maps.
Solution Approach 2:
The patent applies merging by combining multiple routes into a single map structure. The map management unit integrates multiple parking routes that originate from the same start position but lead to different parking positions (PA, PB, etc.) into one unified map. This consolidation reduces map management complexity by eliminating the need to maintain separate maps for each route, while still providing comprehensive coverage of multiple parking positions.
Data Source
AI summary
A parking assistance device is disclosed. The parking assistance device includes processing circuitry connected to a memory. The processing circuitry registers, during learning travel, a map including multiple routes from one parking start position to multiple parking positions. The processing circuitry causes, during automatic parking, a vehicle to perform autonomous travel based on the map. The processing circuitry selects, during automatic parking, a route on which the vehicle is to travel from among the multiple routes.
