Vehicle Navigation Display Filtering Charging Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of charging stations for electric vehicles leads to a cluttered and confusing display on navigation systems, making it difficult for drivers to identify suitable charging points effectively.
Innovation Solution
A method that filters charging stations using multiple criteria, such as proximity, compatibility, and user preferences, to display a manageable number of stations, prioritizing those that are most suitable for the vehicle's current state and the driver's habits, ensuring an uncluttered and relevant representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all available charging stations are displayed on the navigation system, then complete information is provided to the driver, but the display becomes extremely cluttered and confusing
Solution Approach 1:
The patent extracts and displays only the most relevant charging stations based on multiple filter criteria (route compatibility, charging power, user preferences, real-time availability) rather than showing all charging stations. This selective extraction maintains information quality while eliminating display clutter.
Solution Approach 2:
The patent applies different filtering and display strategies to different geographic regions and contexts. Charging stations along the planned route are displayed with different prominence and detail compared to stations off-route, creating a localized, context-appropriate display that avoids universal clutter.
2Ease of operation
If multiple filter criteria are applied to reduce the number of displayed charging stations, then display clarity is improved, but the complexity of the display system increases
Solution Approach 1:
The system automatically applies multiple filter criteria and adjusts display content without requiring manual user configuration. It self-adapts to user behavior patterns, vehicle characteristics, and real-time conditions, reducing the perceived complexity for the user while maintaining sophisticated filtering in the background.
Solution Approach 2:
The system pre-calculates and stores filter criteria, user preferences, and compatibility data before the navigation session begins. This preliminary preparation allows the filtering process to run efficiently during actual use without adding real-time computational complexity to the user interface.
3Loss of information
If charging stations are prioritized based on vehicle state and user behavior, then relevance and energy management are improved, but the difficulty of detecting and measuring suitable stations increases
Solution Approach 1:
The system continuously monitors user interactions with charging station suggestions and vehicle state changes, using this feedback to refine filtering criteria and prioritization algorithms. This feedback loop improves information relevance over time while automating the complex assessment of station suitability.
Solution Approach 2:
The patent replaces manual assessment of charging station suitability with automated electronic evaluation based on vehicle telemetry, user profile data, and real-time charging infrastructure status. This substitution handles the complexity of measuring and detecting suitable stations through computational rather than manual processes.

AI summary
A display method for a vehicle that includes an electric drive and an electric charge accumulator for storing electric energy for the electric drive. Multiple properties of multiple charging stations are provided, which are suitable for charging the electric charge accumulator of the vehicle, and multiple filter criteria are also provided. One particular filter criterion is assigned to one particular property of the multiple properties of the charging stations. The multiple charging stations are filtered, using the multiple filter criteria, for generating a filtered subset of charging stations in such a way that the filtered subset of charging stations has no more than a predetermined number of charging stations. The filtered subset of charging stations is displayed on a display device of the vehicle.
