Autonomous Parking Realignment for Entry Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous parking assist systems fail to ensure proper vehicle alignment and sufficient entry space after initial parking, especially when nearby vehicles change positions or are incorrectly parked, leading to insufficient space for drivers to enter or exit the vehicle.
Innovation Solution
An autonomous parking assist apparatus equipped with an environment information detector (including imaging devices, RADAR, LiDAR, and ultrasonic sensors) and a processor that monitors changes in the parking environment, determines if realignment is necessary, and adjusts the vehicle's position to ensure sufficient space and alignment with surrounding vehicles, using driving, steering, shifting, and braking controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the autonomous parking assist system deactivates after initial parking, then the system operation is simplified and energy is conserved, but the vehicle alignment may become improper when nearby vehicles change positions
Solution Approach 1:
The system performs periodic monitoring of the parking environment at predetermined time intervals after parking completion. The processor determines whether nearby vehicles have exited or entered, and only triggers realignment when environmental changes are detected, rather than continuously monitoring or remaining inactive
Solution Approach 2:
The system uses sensors to detect changes in the parking environment (vehicle exits/entries) and feeds this information back to the processor. Based on the feedback about environmental changes, the system dynamically decides whether realignment is necessary, creating a closed-loop control system
2Reliability
If the system continuously monitors the parking environment, then the vehicle alignment reliability is improved, but the energy consumption and system complexity increase
Solution Approach 1:
Instead of continuous monitoring, the system monitors the parking environment at predetermined time intervals (e.g., every 5 minutes, 10 minutes, or 30 minutes). This periodic monitoring maintains alignment reliability by detecting environmental changes while significantly reducing energy consumption compared to continuous operation
Solution Approach 2:
The monitoring frequency and realignment execution are dynamic rather than static. The system adapts its behavior based on detected environmental changes - intensifying monitoring when changes occur and reducing activity when the environment is stable, optimizing the balance between reliability and energy consumption
3Reliability
If the system performs realignment based on environmental changes, then the vehicle alignment is improved, but the productivity and parking efficiency are reduced due to additional operations
Solution Approach 1:
The system proactively detects environmental changes (vehicle exits/entries) before they cause improper alignment. By anticipating potential alignment issues through continuous environmental monitoring, the system can perform timely realignment rather than waiting for alignment problems to manifest
Solution Approach 2:
The system dynamically determines whether realignment is necessary based on detected environmental changes. Realignment is executed only when changes are detected that would affect alignment, avoiding unnecessary realignment operations and maintaining parking efficiency while ensuring alignment reliability when needed
4Ease of operation
If the system monitors and performs realignment operations, then the ease of operation for drivers is improved, but the device complexity increases
Solution Approach 1:
The system autonomously monitors the parking environment, determines when realignment is necessary, and executes realignment operations without driver intervention. The entire process is self-service, with the system managing alignment maintenance independently, improving driver convenience while the complexity is contained within the automated system

AI summary
An autonomous parking assist apparatus and a method for assisting parking using the apparatus are provided. The autonomous parking assist apparatus includes an environment information detector that detects surrounding environment information of a vehicle and a processor that senses a change in a parking environment using the environment information detector after the vehicle is parked. Additionally, the processor determines whether a realignment of the vehicle is required and performs the realignment of the vehicle based on the determined result.
