Automatic Parking Resumption After Obstacle Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assistance systems fail to resume automatic parking after an obstacle is cleared by the vehicle occupant, causing inconvenience.
Innovation Solution
A parking assistance device that includes a processor to suspend automatic parking upon detecting an obstacle and provide notifications to the occupant, allowing for the obstacle to be cleared before resuming parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic parking is suspended when an obstacle is detected, then safety is improved, but parking efficiency deteriorates because the system cannot automatically resume after the obstacle is cleared
Solution Approach 1:
The system continuously monitors the parking environment during automatic parking operations. When an obstacle is detected, the system suspends parking and provides feedback to the occupant. After suspension, the system keeps monitoring and automatically resumes parking when the obstacle is no longer detected, creating a closed-loop feedback mechanism that ensures both safety and efficiency.
Solution Approach 2:
The parking system performs self-service by automatically detecting obstacles, suspending parking, notifying the occupant, and then automatically resuming parking without requiring manual intervention. The system serves itself by managing the entire obstacle handling process autonomously, from detection to resumption.
2Object-affected harmful factors
If automatic parking stops when an obstacle is detected, then collision risk is reduced, but convenience deteriorates because the occupant cannot easily resume parking after clearing the obstacle
Solution Approach 1:
The system automatically handles the resumption process by monitoring the environment and initiating parking again without requiring the occupant to manually restart the system. This self-service approach maintains safety while significantly improving convenience.
Solution Approach 2:
The system maintains continuous monitoring of the parking environment even after suspension. This continuous action ensures that as soon as the obstacle is cleared, the system can immediately resume parking, eliminating gaps and maintaining the flow of the parking operation.
3Loss of time
If the system continuously monitors for obstacle clearance, then parking resumption is timely, but energy consumption increases
Solution Approach 1:
The system employs periodic monitoring at strategically determined intervals after obstacle detection, rather than continuous monitoring. This periodic approach maintains timely detection of obstacle clearance while significantly reducing energy consumption compared to constant monitoring.
Solution Approach 2:
The system performs preliminary monitoring and preparation for resumption before fully restarting the parking sequence. This allows the system to be ready to resume quickly when conditions are favorable, minimizing delays while avoiding unnecessary continuous operation.

AI summary
A parking assistance device is configured to automatically park a vehicle at a predetermined parking position. The parking assistance device includes a memory, and a processor coupled to the memory. The processor is configured to: store a parking route to the parking position; perform detection at least around the vehicle to obtain detection information; control traveling in automatic parking; make a notification to an occupant of the vehicle; and suspend, based on at least one of the detection information and a motion of the occupant, the traveling in the automatic parking. The processor is configured to: suspend the traveling in the automatic parking in at least one of a case in which the processor detects an obstacle interfering during the automatic parking and a case in which the occupant stops the vehicle, and make a notification as to suspension of the traveling of the automatic parking, to the occupant.
