Automatic Parking System Communication Interruption Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic valet parking systems face inefficiencies due to communication interruptions between parking lot management servers and autonomous driving vehicles, leading to reduced parking efficiency and potential collisions.
Innovation Solution
An automatic parking system that issues autonomous travel reservation instructions to vehicles experiencing communication interruptions, allowing them to continue navigating to their target routes, and adjusts the routes of other vehicles to avoid collisions and prevent overcrowding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous driving vehicle stops when communication is interrupted, then collision safety is improved, but parking efficiency deteriorates
Solution Approach 1:
The system pre-calculates and reserves alternative routes for autonomous driving vehicles before communication interruptions occur. When communication is interrupted, the vehicle can immediately execute the pre-reserved autonomous travel plan without stopping, thereby maintaining parking efficiency while ensuring safety through advance preparation of contingency paths
Solution Approach 2:
The system dynamically adjusts the autonomous driving vehicle's travel behavior based on communication status. When communication is available, the vehicle follows normal controlled travel. When communication is interrupted, the vehicle automatically switches to autonomous travel mode using pre-reserved routes, creating a dynamic response that balances safety and efficiency
2Productivity
If the autonomous driving vehicle autonomously travels when communication is interrupted, then parking efficiency is improved, but collision risk increases
Solution Approach 1:
The system pre-calculates alternative routes and reserves them for autonomous travel before communication interruptions occur. This preliminary preparation ensures that when autonomous travel becomes necessary, the vehicle has safe, pre-planned paths to follow, reducing collision risk while maintaining efficiency
Solution Approach 2:
The system introduces a route reservation mechanism as an intermediary between the control server and the autonomous vehicle. The reserved route information acts as a mediator that guides the vehicle safely through the parking area during autonomous travel, reducing direct dependency on real-time communication while maintaining safety
3Productivity
If multiple autonomous driving vehicles are instructed to autonomously travel when communication is interrupted, then parking efficiency is improved, but overcrowding occurs
Solution Approach 1:
The system assigns different reserved routes to different autonomous driving vehicles based on their specific locations and destinations within the parking area. This localized route allocation ensures that vehicles travel through different paths, distributing traffic flow evenly and preventing overcrowding in any single area while maintaining overall parking efficiency

AI summary
An automatic parking system instructs a plurality of autonomous driving vehicles in a parking lot such that each autonomous driving vehicle travels along a target route and parks in a target parking space within the parking lot. The automatic parking system includes: a vehicle instruction unit configured to direct the autonomous driving vehicle the target route for reaching the target parking space, and to issue a pause instruction and an advance instruction to the autonomous driving vehicle autonomously traveling along the target route. The vehicle instruction unit issues an autonomous travel reservation instruction for causing the autonomous driving vehicle to autonomously travel along the target route when communication with the autonomous driving vehicle is interrupted.
