Vehicle Parameter Display with Visual Conversion Graph
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle parameter display systems do not effectively convey the interconnections between different parameters, such as energy reserve, distance covered, and remaining range, making it difficult for drivers to understand how changes in one parameter affect others, particularly in electric vehicles.
Innovation Solution
A method and device that graphically represent the conversion of changes in one parameter into another using elongate objects on a display, allowing drivers to visualize the impact of parameter changes and influences from other factors, such as driving mode, style, and navigation, on energy reserve and remaining range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If separate displays are used for each vehicle parameter, then each parameter value can be clearly shown, but the connection between different parameters cannot be recognized by the driver
Solution Approach 1:
The patent combines multiple separate parameter displays into a single integrated graphical representation. The display shows the first parameter (e.g., energy reserve) and second parameter (e.g., remaining range) together with visual elements that illustrate their interconnection, allowing drivers to understand how changes in one parameter affect another without requiring multiple separate displays
Solution Approach 2:
The patent introduces visual intermediary elements such as graphical icons, arrows, and proportional representations that mediate between the first and second parameters. These visual intermediaries make the abstract relationship between parameters concrete and understandable, showing drivers how energy reserve converts to remaining range in an intuitive manner
2Measurement precision
If numerical values are displayed for parameters, then precise information is provided, but drivers cannot intuitively understand the impact of parameter changes
Solution Approach 1:
The patent transforms numerical parameter values into visual representations with varying sizes, lengths, or positions. For example, the remaining range is displayed as a graphical element whose length corresponds to the distance, and whose position or size changes in response to energy reserve levels. This allows drivers to intuitively grasp parameter impacts without needing to interpret numerical changes
Solution Approach 2:
The patent employs color variations to indicate different states and relationships between parameters. Visual elements representing energy reserve and remaining range use color changes to show availability, consumption rates, and interconnections, making the information both precise and intuitively understandable at a glance

AI summary
The present invention relates to a method and a device (2) for displaying vehicle parameters comprising at least a first and a second parameter. In the method according to the invention, a value of the first parameter and a value of the second parameter are determined and displayed on a display surface (8). Furthermore, the value of the first parameter is changed, and at least a first part of the change in the value of the first parameter is converted into a change in the value of the second parameter. A first display element (9) is generated on the display surface (8), by means of which the conversion of the change in the value of the first parameter into the change in the value of the second parameter is graphically represented.
