Facility Rating Using Vehicle Parking Position Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facility evaluation methods face challenges in providing reliable ratings due to difficulties in accurately associating vehicle position information with target facilities, especially when GPS signals are disrupted within facilities, and lack of practical use of additional probe information such as user attributes.
Innovation Solution
A facility evaluation device and method that determines if a vehicle is parked in a facility's parking area, using a system with a receiving unit for position information, a facility information saving unit, and an evaluation unit to generate reliable ratings based on parking data, incorporating user attributes and vehicle classification for more accurate assessments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS positioning is used to track vehicle position, then position information can be obtained, but GPS signals become unavailable when entering facilities, causing loss of position data
Solution Approach 1:
The patent introduces map information and facility information as intermediary data layers between GPS positioning and facility identification. When GPS signals are unavailable inside facilities, the system uses the last known position combined with map data and facility location data to determine which facility the vehicle is at, rather than directly relying on real-time GPS coordinates.
Solution Approach 2:
The system pre-loads and stores map information and facility information (including parking area locations) before GPS signal loss occurs. This preliminary preparation of spatial data allows the system to continue determining facility presence even when real-time positioning is unavailable.
2Ease of operation
If manual posting is used for facility evaluation, then user feedback can be collected, but arbitrary posts reduce confidence in ratings
Solution Approach 1:
The system automatically generates evaluation data without requiring manual user input. The facility evaluation device autonomously determines vehicle presence at facilities using position information and compares it against facility data, thereby eliminating the need for users to manually post evaluations while maintaining data reliability.
Solution Approach 2:
The system implements automatic feedback collection by continuously monitoring vehicle position data and generating evaluation information based on actual vehicle-facility interactions. This automated feedback loop ensures consistent, objective evaluation data without human intervention.
3Quantity of substance
If position information from various terminals is referenced, then evaluation data can be collected, but associating detected position with target facility becomes difficult
Solution Approach 1:
The system creates a universal matching framework that works across different terminal types (vehicles, portable devices). By using standardized map information and facility information data structures, the system can associate position data from any terminal with the correct facility regardless of the terminal type, enabling multi-functional position-facility association.

AI summary
A highly reliable facility evaluation information (rating information) that is free of arbitrary ratings. A server system includes a facility rating information creation and updating unit that grants a rating with regard to a facility to be rated on the basis of parking information. The parking information is obtained by assessing whether the present position of a mobile body, which is being carried together with a vehicle, has been parked in the area of the facility to be rated whereat parking is possible. A facility rating provision unit that outputs the rating regarding to the facility to be rated, which has been granted by the facility rating information creation and updating unit.
