Vehicle Display Orientation Cues That Preserve Forward Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems project destination icons that can obstruct the view of the scene ahead, annoying occupants when the destination is close or obstructed, and fail to consider the positional relationship between the vehicle and the destination.
Innovation Solution
A vehicle display system that acquires position information for the vehicle and destination, displaying an orientation image only when the distance or visibility conditions are favorable, and adjusting the image's focus and size based on the vehicle's proximity to the destination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a destination icon is always displayed at the center of the display region, then the orientation information is clearly conveyed to the occupant, but the visibility of the scene ahead is impaired when the destination is close or obstructed
Solution Approach 1:
The display position of the destination icon is made dynamic rather than fixed. The icon moves between the center position (when destination is far) and the lower right position (when destination is close or obstructed), allowing the system to adapt to different driving scenarios and balance information display with scene visibility
Solution Approach 2:
Different display positions are used for different spatial relationships between vehicle and destination. The center position is used when the destination is far away, while the lower right position is used when the destination is close or obstructed, optimizing the display strategy for local conditions
2Loss of information
If the destination icon is displayed prominently, then the orientation information is easily perceived, but the occupant is annoyed when the icon obstructs the view of the destination in the scene ahead
Solution Approach 1:
The system dynamically adjusts the icon's display position based on the spatial relationship between the vehicle and destination. When the destination is close or obstructed, the icon moves to the lower right position, reducing visual conflict and improving occupant comfort while still conveying orientation information
3Device complexity
If the destination icon remains stationary at the center, then the display system is simple, but it cannot adapt to different positional relationships between the vehicle and destination
Solution Approach 1:
The display system incorporates dynamic position adjustment based on vehicle-destination spatial relationship. The control system monitors distance and obstruction conditions, then automatically adjusts the icon position between center and lower right, providing adaptability without excessive complexity
Solution Approach 2:
The system pre-defines two optimal display positions (center and lower right) for different scenarios. By preparing these positions in advance and switching between them based on conditions, the system achieves adaptability without requiring complex real-time optimization algorithms

AI summary
A vehicle display device configured to display a predetermined image on a display region depicting a scene ahead of a vehicle. The vehicle display device includes memory and a processor connected to the memory. The processor is configured to acquire position information for the vehicle and position information for a destination point, and to display a first image indicating an orientation of the destination point at the display region in a case in which a relationship between the position of the vehicle and the position of the destination point satisfies a predetermined condition relating to visibility.
