Parking Assist System Using Drone for Autonomous Vehicle Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assist methods are inadequate for scenarios where autonomous vehicles and general vehicles are parked side by side, as they do not account for the simultaneous presence of both vehicle types in a parking lot, leading to inefficiencies in entry and exit maneuvers.
Innovation Solution
A parking assist system that employs an unmanned aerial vehicle (drone) as a mobile body to sense vehicle behavior and transmit signals to a management unit, which determines whether a vehicle is autonomous or general and directs autonomous vehicles to create entry/exit routes, while also assisting general vehicles by relocating obstructing autonomous vehicles to enable smooth entry and exit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous vehicles are parked side by side with general vehicles in a parking lot, then parking space utilization is improved, but entry and exit processes become obstructed due to lack of coordination between vehicle types
Solution Approach 1:
The management unit acts as an intermediary between autonomous vehicles and general vehicles. It receives entry/exit requests from general vehicles, identifies obstructing autonomous vehicles, and transmits travel signals to those autonomous vehicles to relocate. This mediator coordinate the interactions between the two vehicle types, enabling smooth entry and exit while maintaining high parking space utilization.
Solution Approach 2:
The system performs preliminary actions by proactively identifying and relocating autonomous vehicles that may obstruct future entry or exit operations. When a general vehicle requests entry or exit, the management unit beforehand determines which autonomous vehicles need to move and transmits travel signals to them, preventing obstruction before it occurs.
2Extent of automation
If autonomous vehicles autonomously determine their parking positions without coordination, then operational independence is improved, but congestion and obstruction occur in the parking lot
Solution Approach 1:
The management unit establishes a feedback mechanism where autonomous vehicles report their parking positions and receive travel signals when obstruction is detected. The system continuously monitors the parking lot state, and when a general vehicle needs entry or exit, the management unit provides feedback to relevant autonomous vehicles to relocate, maintaining both automation and efficiency.
3Ease of operation
If the system monitors and coordinates all vehicle movements in the parking lot, then entry and exit obstruction is reduced, but system complexity increases
Solution Approach 1:
The management unit serves multiple functions: it receives entry/exit requests from general vehicles, monitors autonomous vehicle positions, determines obstruction scenarios, and transmits travel signals to autonomous vehicles. This multi-functional approach consolidates coordination tasks into a single system, managing complexity while improving operational ease.

AI summary
A parking assist system for use in a parking lot including parking spaces for a plurality of vehicles includes: a vehicle sensor which determines whether an assisted vehicle attempting to enter or exit one of the parking spaces is a general vehicle that travels through vehicle operation by a driver or an autonomous vehicle capable of self-driving according to an external travel signal; and a travel signal transmitter which, when the assisted vehicle is determined as the general vehicle, transmits, to a specific autonomous vehicle among parked autonomous vehicles, a travel signal for traveling to an available position for enabling the entry or the exit of the assisted vehicle.
