Vehicle Display Control for Adaptive Nearby-Vehicle Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control devices for vehicles struggle to provide appropriate information on surrounding vehicles, as too little information can be insufficient and too much can be overwhelming for occupants, especially during automated driving modes.
Innovation Solution
A display control device that includes a vehicle-information acquiring unit and a display control unit, which acquires and displays information on nearby vehicles in a switching manner between a detailed first image and a less detailed second image, based on the driving mode and occupant's anxiety level, adjusting the amount of information shown according to the vehicle's state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If detailed information on surrounding vehicles is displayed, then occupant awareness of surrounding conditions is improved, but information overload and obtrusiveness occur
Solution Approach 1:
The display control device dynamically adjusts the amount of information displayed based on real-time driving conditions, vehicle state, and occupant behavior. The system switches between different display modes (first display mode with detailed information, second display mode with reduced information) to optimize information delivery without causing overload
Solution Approach 2:
The system changes display parameters such as information density, detail level, and presentation format based on detected conditions. When the vehicle is stationary or moving slowly with high surrounding vehicle density, more detailed information is displayed. When moving at high speed or in low-density areas, less detailed information is shown to prevent information overload
2Object-affected harmful factors
If minimal information on surrounding vehicles is displayed, then information overload is reduced, but occupant awareness of surrounding conditions deteriorates
Solution Approach 1:
The display system dynamically adapts information quantity based on contextual factors including vehicle speed, surrounding vehicle density, and occupant attention patterns. This ensures sufficient information is provided when needed while minimizing information when it would be overwhelming
Solution Approach 2:
The system provides different levels of information detail in different display regions or contexts. Critical safety-related information is always displayed with appropriate detail, while less critical information is adjusted based on current conditions, ensuring important information is never lost while preventing overall information overload
3Loss of information
If fixed detailed display is used, then information completeness is maintained, but adaptability to different driving situations is reduced
Solution Approach 1:
The display control device transitions from a fixed display approach to a dynamic adaptive system that responds to changing driving conditions, vehicle state, and occupant behavior patterns, maintaining information completeness when needed while adapting presentation to suit different situations
Solution Approach 2:
The display system is designed to perform multiple functions by adjusting its information presentation based on context. It can provide detailed surveillance information when the vehicle is stationary, reduced information during high-speed travel, and customized views based on occupant preferences, making the single display system universally applicable to diverse driving scenarios

AI summary
A display control device includes a vehicle-information acquiring unit and a display control unit. The vehicle-information acquiring unit is configured to acquire information on at least one nearby vehicle close to a vehicle. The display control unit is configured to display an image showing the nearby vehicle based on the information on the nearby vehicle. The display control unit displays, in a switching manner, a first image showing the nearby vehicle and a second image showing the nearby vehicle having a smaller amount of information than the first image.
