Vehicle Display Layout for Enlarging Travel Control Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems in vehicles risk obscuring critical travel control information from the driver when switching displays during travel due to insufficient sizing of necessary information.
Innovation Solution
A system that dynamically adjusts display areas by enlarging the first area displaying travel control information and reducing the second area when the enlarged display portion exceeds the first area, ensuring critical information remains visible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display switches to show application program information during vehicle travel, then the driver can access application functions, but the travel control information may not be displayed in sufficient size
Solution Approach 1:
The display screen is divided into multiple regions: a first region dedicated to travel control information and a second region for application program information. This segmentation allows both types of information to be displayed simultaneously in appropriate sizes without interfering with each other, resolving the contradiction between display versatility and display size precision.
Solution Approach 2:
Different regions of the display are assigned different functions and quality characteristics. The first region maintains high visual prominence and sufficient size for travel control information, while the second region displays application information with adjusted sizing. This local differentiation ensures that critical travel information always appears in sufficient size regardless of application display activity.
2Quantity of substance
If the display area for application information is increased, then more application details can be shown, but the area for travel control information is reduced
Solution Approach 1:
The display area is segmented into a first region for travel control information and a second region for application information. This segmentation establishes clear boundaries that prevent application information from encroaching on travel control information space, ensuring that increasing application display capacity does not reduce the travel control information area.
Solution Approach 2:
Instead of competing for the same display space, the solution places travel control information and application information in different spatial regions of the display. This dimensional separation allows both information types to be displayed simultaneously at appropriate sizes, resolving the zero-sum trade-off between information display capacity and travel control information area.

AI summary
A display device for vehicles includes a display unit installed in front of a driver seat of a vehicle and having a first area and a second area. The first area displays first information used for travel control of the vehicle. The second area is provided at a position farther from the driver seat than the first area and displaying second information other than the first information. The display device further includes a control unit performing, in response to a user's operation, at least one of enlarging a display portion of information displayed on the display unit or adding new information to the display unit; and a determination unit determining, when the display portion of the first information displayed in the first area is enlarged or when new first information is added to the first area, whether or not a size of the enlarged display portion of the first information or a size of the display portion of the new first information to be added is larger than the first area. When the determination unit determines that the size of the enlarged display portion of the first information or the size of the display portion of the new first information to be added is larger than the first area, the control unit reduces the second area, enlarges the first area, and displays the first information whose display portion is enlarged or the new first information in the enlarged first area. When the display portion of the second information displayed in the second area is enlarged or when new second information is added to the second area, the determination unit determines whether or not a size of the enlarged display portion of the second information or a size of the display portion of the new second information to be added is larger than the second area. When the determination unit determines that the size of the enlarged display portion of the second information or the size of the display portion of the new second information to be added is larger than the second area, the control unit maintains the size of the second area and adjusts the size of the enlarged display portion of the second information or the size of the display portion of the new second information to be added to match the size of the second area.
