EV Charging Route Display Using Proximity-Ordered Facility Icons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems display information on charging facilities superimposed on maps, which can reduce visibility due to changes in positional relationship and display status as the vehicle moves, making it difficult for users to easily identify charging locations and availability.
Innovation Solution
A navigation system that displays charging facility information on a schematic diagram ordered by proximity to the vehicle's current position, using icons to indicate charging equipment and vehicle availability, maintaining fixed positions until the facility is passed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If charging facility information is displayed superimposed on maps, then the information can be shown in the context of geographic location, but the visibility and ease of reading deteriorates due to changes in positional relationship and display status as the vehicle moves
Solution Approach 1:
The display system is segmented into two distinct components: a map display showing geographic location and a separate schematic diagram showing charging facility information. This segmentation allows each display element to serve its specific function without interfering with the other, thereby maintaining visibility of charging information while preserving the geographic context provided by the map.
Solution Approach 2:
A schematic diagram acts as an intermediary between the map display and the driver. Instead of directly superimposing charging facility information on the map, the system uses the schematic diagram as a mediator to present this information in a separate, easily readable format that updates based on the vehicle's position relative to charging facilities.
2Ease of operation
If charging facility information is displayed on a schematic diagram in order of proximity, then the ease of reading improves, but the ability to show geographic context is reduced
Solution Approach 1:
The display is segmented into two functional areas: the map provides geographic location context while the schematic diagram provides ease of reading for charging facility information. This division allows both requirements to be satisfied simultaneously without compromise.
Solution Approach 2:
The system merges the map display and schematic diagram display into a unified interface. Both displays work together to provide comprehensive information - the geographic context from the map and the organized charging facility details from the schematic diagram - creating a more complete information presentation than either could provide alone.

AI summary
A control unit of an information processing device searches for a charging facility that is included in one or more facilities located on a planned travel route of a user vehicle and is either one or both of a facility that has charging equipment and a facility to which a charging vehicle for charging the user vehicle is dispatched. The control unit of the information processing device outputs display information for displaying charging facility information on whether the user vehicle can be charged at the charging facility, which has been searched for, on a schematic diagram on which information on the one or more facilities is displayed in order of proximity to the current position of the user vehicle.
