Vehicle Display Layout for Travel Assist Status Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle display systems locate status display elements at less visible ends of the meter display, making it harder for drivers to see them when they are more likely to look, and more likely to be bothered by them when they are less likely to look.
Innovation Solution
The vehicle display control device adjusts the display area for status elements based on travel assist control status and road type, positioning them in a more visible area when the driver is likely to look, such as on an expressway, reducing botheration and enhancing visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the status display element is located at the right end of the meter display, then the driver is less likely to be bothered by it when not looking at it, but the driver is more likely to have difficulty seeing it when more likely to look at it
Solution Approach 1:
The patent applies the dynamics principle by making the display area of the status display element dynamically adjustable based on driving conditions. The control unit changes the display area between a first area (less visible) and a second area (more visible) according to whether travel assist control is active and whether the vehicle is on an expressway. This resolves the contradiction by adapting the visibility characteristics to the actual need for information at different times.
Solution Approach 2:
The patent applies the parameter changes principle by modifying the display parameters (display area position and size) based on changing driving conditions. The control unit adjusts the display area parameters in response to changes in travel assist control status and road type, thereby optimizing the balance between driver botheration and information visibility under different operating conditions.
2Ease of operation
If the status display element is located at a less visible area, then driver botheration is reduced when not looking, but visibility when needed is compromised
Solution Approach 1:
The display area is made dynamic and adjustable based on driving conditions. When travel assist control is active or the vehicle is on an expressway, the status display element is shown in a more visible second area to ensure reliability of information accessibility. When these conditions are not met, it is shown in a less visible first area to maintain ease of operation and reduce driver distraction.
3Adaptability or versatility
If the display area is fixed, then the system is simple, but it cannot adapt to different driving conditions where visibility needs vary
Solution Approach 1:
The patent implements a dynamic display control system that adapts to different driving conditions by changing the display area based on travel assist control status and road type. This provides adaptability to varying visibility needs while keeping the control logic relatively simple - the control unit only needs to check two conditions (travel assist control on/off and expressway detection) to determine the appropriate display area.

AI summary
The vehicle display control device includes a control unit capable of executing a travel assist control for causing the vehicle to travel so that the vehicle speed coincides with the set vehicle speed or the vehicle follows the preceding vehicle, and a display device in which a status display element relating to an operating status of the travel assist control is displayed in a preset display area. The control unit is configured to set a display area to a first area when neither a first condition that travel assist control is on nor a second condition that the vehicle is traveling on an expressway is satisfied, and to set the display area to a second area when either or both of the first condition and the second condition are satisfied. The second area is set at a position that is more visible to a driver than the first area.
