In-Vehicle Navigation Charging Point Public Availability Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle navigation systems do not effectively differentiate between public and private charging points for electric vehicles, leading to potential misuse of private charging points by other vehicles.
Innovation Solution
An in-vehicle navigation apparatus and server apparatus that determine the public availability of charging points by referencing facility information in map data, allowing only public charging points to be registered and used by other vehicles, thereby avoiding the use of private charging points, such as those located at personal houses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If all charging points are registered in the map database without differentiation, then the quantity of charging point information is increased, but private charging points may be misused by other vehicles
Solution Approach 1:
The patent segments charging points into two distinct categories: public charging points and private charging points. This segmentation is achieved by introducing a classification mechanism that distinguishes between charging points accessible to the general public and those restricted to specific users, thereby preventing misuse of private charging points while maintaining comprehensive charging point information in the database.
2Manufacturing precision
If charging points are categorized by charging frequency or charging time, then the manufacturing precision of charging point registration is improved, but the ability to prevent private charging point misuse is insufficient
Solution Approach 1:
The patent applies local quality by introducing a specific attribute (public availability flag) to charging point data that indicates whether a charging point is publicly accessible or privately restricted. This localized differentiation within the charging point information structure enables precise control over which charging points can be used by other vehicles, thereby preventing misuse of private charging points while maintaining detailed registration information.
Data Source
AI summary
An in-vehicle navigation apparatus to support sharing of electric vehicle charging point information such that other electric vehicles can use a charging point where its own electric vehicle is charged. If the in-vehicle navigation apparatus determines that a current position is a charging point on the basis of charge information about an electric vehicle, the navigation apparatus determines whether the charging point has public availability by referring to facility information, such as facility positions in map data stored in a map data storage unit. The in-vehicle navigation apparatus may transmit charging points having public availability to a server apparatus and not transmit the charging points having no public availability to the server apparatus. Vehicles may download charging points uploaded by other vehicles.
