Adaptive Vehicular Display Adjusting Content for Driver Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular display systems face challenges in reducing manufacturing costs and ensuring improved visibility of display information for drivers, particularly due to complex configurations and obstructions from the steering wheel.
Innovation Solution
A vehicular display system utilizing a mobile device with a mobile display part that adjusts display size and position based on the driver's eye positions, using an imaging unit to recognize the driver's eyes and a reference position, allowing the system to reconfigure content placement to avoid obstruction by the steering wheel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a mobile device is used as the display unit instead of a HUD or fixed display, then manufacturing cost is reduced, but visibility of the display screen is compromised due to driver position variations and steering wheel obstruction
Solution Approach 1:
The patent applies dynamics by making the display position and size adjustable based on detected driver eye positions. The display unit dynamically changes its characteristics to accommodate different driver positions and steering wheel angles, transforming a static display system into an adaptive one that maintains visibility while using cost-effective mobile devices
Solution Approach 2:
The system changes display parameters (position and size) based on detected eye positions and steering wheel angle. By adjusting these parameters in real-time, the system optimizes visibility for each driver configuration while maintaining the use of inexpensive mobile display devices
2Device complexity
If the display position is fixed to reduce complexity, then device complexity is reduced, but the display may be obstructed by the steering wheel for drivers with different eye positions
Solution Approach 1:
The system performs self-adjustment by automatically detecting driver eye positions and steering wheel angle, then autonomously modifying display characteristics without requiring manual intervention. This self-service capability maintains visibility across different driver configurations while keeping the control system relatively simple
Solution Approach 2:
The system uses feedback from eye position detection and steering wheel angle sensing to continuously adjust display parameters. This closed-loop control ensures the display remains visible and accessible despite variations in driver position and steering wheel orientation

AI summary
A vehicular display system includes a mobile device (28) having a mobile display part (74) and adapted to be disposed in a predetermined position in a vehicle. The mobile display part is configured to display contents such that at least one of a display size and a display position of each of the contents is changed in accordance with positions of eyes (51) of a driver (50) sitting on a driver's seat (18) in the vehicle with respect to a reference position in the vehicle. Preferably, the mobile device has an imaging unit (71) for picking up an image and recognizes the positions of the driver's eyes and the reference position from the image picked up by the imaging unit. The vehicular display system may further include a vehicle on-board unit fixedly mounted in the vehicle.
