Steering Wheel Coverage Compensation for Vehicle Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, the display area covered by the steering wheel obstructs critical driving information, increasing the risk of accidents as drivers must physically move to access important data like vehicle speed and navigation.
Innovation Solution
A system that includes a position-adjustable steering wheel and driver's seat, along with image sensors and a controller, which determines the driver's eye position and adjusts the display output to ensure critical information is visible without being covered by the steering wheel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a large display is installed to provide comprehensive driving information, then the information display capability is improved, but the steering wheel may cover critical information reducing visibility
Solution Approach 1:
The display output position is dynamically adjusted based on real-time detection of the driver's eye position and steering wheel angle. The controller continuously monitors these parameters and automatically repositions critical driving information to areas not covered by the steering wheel, making the system adaptive to changing driving conditions without manual intervention.
Solution Approach 2:
The system employs image sensors to detect the driver's eye position and feeds this information back to the controller. The controller processes this feedback along with steering wheel angle data to determine the optimal display position, creating a closed-loop control system that ensures critical information remains visible to the driver.
2Loss of information
If the display position is fixed to avoid being covered by the steering wheel, then information visibility is improved, but the display cannot provide comprehensive information across the full display area
Solution Approach 1:
The display output position transitions from a fixed location to a dynamic position that changes based on steering wheel angle and driver eye position. This allows the display to utilize the full display area when needed while automatically relocating critical information to visible areas when the steering wheel obstructs the view.
Solution Approach 2:
Different areas of the display are assigned different functions based on their visibility characteristics. Critical driving information is selectively positioned in areas not covered by the steering wheel, while other areas can display supplementary information, creating a spatial differentiation of display content quality and importance.
3Loss of information
If manual adjustment of display position is required to avoid steering wheel coverage, then information visibility is improved, but the ease of operation deteriorates due to additional driver actions needed
Solution Approach 1:
The display system performs self-adjustment by automatically detecting the driver's eye position and steering wheel angle, then repositioning critical information without requiring any manual input from the driver. The system serves itself by monitoring its own operational parameters and making necessary adjustments autonomously.
Solution Approach 2:
Real-time feedback from image sensors detecting eye position and steering wheel angle enables the controller to automatically adjust display position, eliminating the need for manual intervention and ensuring critical information remains visible throughout driving operations.

AI summary
A vehicle includes: a position-adjustable steering wheel, a position-adjustable driver's seat, a display extending on the dashboard from one side facing the driver's seat to another side in which a center fascia is disposed, at least one image sensor configured to capture a vehicle interior image to obtain the vehicle interior image, a storage configured to store driver's seat positioning information of the driver's seat and steering wheel positioning information of the steering wheel, and a controller configured to obtain eye position information indicating a position of each of eyes of the driver with respect to the steering wheel based on at least one of the driver's seat positioning information or the vehicle interior image, determine a covered area on the display, covered by the steering wheel, based on the eye position information and the steering wheel positioning information, and adjust an output position of an image output on the display based on the covered area.
