Automated Valet Parking Evacuation Routing for Clear Exit Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automated valet parking systems, vehicles parked on exit routes can hinder the exiting process of other vehicles, leading to potential bottlenecks and inefficiencies in parking lot management.
Innovation Solution
An automated valet parking management system that allocates tentative parking spaces on passages and controls vehicle positions using map and vehicle management information to determine evacuation routes for vehicles parked on exit routes, ensuring smooth exit operations by relocating vehicles to avoid interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a vehicle is parked in a tentative parking space on a passage to maximize parking capacity, then the parking lot can accommodate more vehicles, but the exit route of exit vehicles may be hindered
Solution Approach 1:
The system performs preliminary identification of vehicles parked on exit routes and pre-plans evacuation routes before exit vehicles arrive. When an exit vehicle requests to leave, the management device has already identified any blocking vehicles and prepared alternative parking spaces, enabling quick resolution without hindering the exit process.
Solution Approach 2:
The management device acts as an intermediary that coordinates between vehicles parked on passages and exit vehicles. It identifies blocking vehicles, determines appropriate evacuation routes, and manages the relocation process to ensure exit routes remain clear while maximizing parking utilization.
2Ease of operation
If vehicles are evacuated from tentative parking spaces on exit routes, then exit routes are secured for exiting vehicles, but additional processing and vehicle movement are required
Solution Approach 1:
The system identifies vehicles parked on exit routes and determines evacuation routes in advance, before exit vehicles need to leave. This preliminary preparation minimizes the actual evacuation time when an exit request is made, as the management device already has a planned solution ready.
Solution Approach 2:
The management device automatically manages the evacuation process by identifying blocking vehicles, determining evacuation routes, and coordinating vehicle movements without requiring manual intervention. This automated self-service approach reduces processing time and ensures quick response to exit requests.
3Ease of operation
If multiple vehicles are evacuated along evacuation routes, then exit routes are cleared effectively, but fuel consumption and processing load increase
Solution Approach 1:
The system applies evacuation measures selectively only to vehicles that are actually blocking exit routes, rather than evacuating all vehicles on passages. The management device identifies specific blocking vehicles and determines evacuation routes only when necessary, minimizing unnecessary vehicle movements and associated fuel consumption.
Solution Approach 2:
The system dynamically adjusts the decision to evacuate vehicles based on real-time conditions such as the presence of exit vehicles, available alternative parking spaces, and current traffic patterns. This parameter-based decision-making ensures evacuation occurs only when truly necessary, optimizing the balance between exit route accessibility and energy consumption.

AI summary
An automated valet parking (AVP) management system allocates a tentative parking space on a passage in a parking lot to an entry vehicle. When a first vehicle parked in a first regular parking space exits, the AVP management system identifies a first tentatively-parked vehicle parked in a first tentative parking space on an exit route of the first vehicle, and determines a first evacuation route for evacuating the first tentatively-parked vehicle so as not to hinder exiting of the first vehicle. The AVP management system identifies a second tentatively-parked vehicle parked in a second tentative parking space that is not present on the exit route but is present on the first evacuation route, and determines a second evacuation route for evacuating the second tentatively-parked vehicle so as not to hinder the exiting of the first vehicle and evacuation of the first tentatively-parked vehicle.
