Shared Parking-Lot Data for Autonomous Parking Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assist systems do not allow for the sharing of parking lot information between vehicles, limiting the ability to utilize previously used parking lots effectively.
Innovation Solution
A parking assist system comprising a server device and a parking assist device that communicate to share parking lot information, allowing the host vehicle to use previously acquired information to park in a parking section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parking lot information is stored locally in each vehicle, then each vehicle can independently perform parking assistance, but parking lot information cannot be shared between vehicles
Solution Approach 1:
A server device is introduced as an intermediary between vehicles to enable information sharing. The server stores parking lot information received from one vehicle and transmits it to other vehicles, allowing information exchange without compromising individual vehicle independence. Each vehicle maintains its own parking assist device and can still operate independently, while the server facilitates collaborative information sharing across the vehicle fleet.
2Ease of operation
If parking assistance is provided for all parking operations, then drivers receive consistent support, but unnecessary assistance is provided when drivers do not need it
Solution Approach 1:
The system incorporates driver feedback through acceptance/rejection inputs. When a driver receives a parking assistance proposal, their response (accept or reject) is fed back to the parking assist controller. This feedback mechanism allows the system to learn from driver preferences and adjust future assistance provision, ensuring support is provided only when drivers actually need it rather than forcing assistance on all operations.
Solution Approach 2:
The parking assistance system transitions from a static always-on approach to a dynamic responsive approach. The system continuously monitors driver behavior, parking conditions, and acceptance patterns, adjusting its assistance provision in real-time. This dynamic adaptation allows the system to provide consistent support when needed while avoiding unnecessary intervention when drivers are capable of handling parking independently.
3Productivity
If parking lot information is shared across multiple vehicles, then parking efficiency is improved, but system complexity increases due to server communication requirements
Solution Approach 1:
The server device performs multiple functions: storing parking lot information, receiving data from vehicles, transmitting information to vehicles, and managing communication protocols. By consolidating these diverse functions into a single multi-functional server platform, the system achieves information sharing and improved parking efficiency without proportionally increasing overall system complexity. The server's universal capabilities allow it to handle various tasks efficiently within a unified architecture.

AI summary
To provide a parking assist system and a parking assist device that are capable of sharing parking lot information on parking lots in which vehicles have parked before. A server storage portion (310) of a server device (3) stores parking lot information (122) that is acquired when a vehicle (V) is parked in a parking section of a parking lot. A parking assist controller (108) of a parking assist system (1) is configured to control the vehicle (V) to park itself in the parking section of the parking lot in accordance with the parking lot information (122) acquired from the server device (3).
