Steering-Wheel Phone Display Adaptation for Speed and Touch Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information display systems are limited in their ability to dynamically adjust the display of information based on driving conditions and user needs, often overwhelming drivers with too much information at once.
Innovation Solution
A vehicle information display apparatus and method that utilizes a mobile phone mounted on the steering wheel, equipped with an input unit, memory, and processor. The system adjusts the transparency or button size of the mobile phone screen based on driving speed, and further adapts by increasing button sizes when the user's hand approaches the phone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display shows all available information, then the user has access to complete vehicle information, but the driver is overwhelmed with too much information at once
Solution Approach 1:
The display information is segmented into different categories (driving safety information, infotainment information, vehicle status information) and presented in a hierarchical manner. Critical driving safety information is prioritized and displayed prominently, while less critical information is available on demand or displayed in a less prominent manner.
Solution Approach 2:
The display dynamically adjusts the amount and type of information shown based on driving conditions. At high speeds, only essential information is displayed. At low speeds or when parked, more detailed information becomes available. The system adapts to the driver's needs in real-time.
2Loss of information
If the display shows detailed information, then the user has complete information access, but the readability and visibility are reduced
Solution Approach 1:
Different regions of the display have different quality characteristics. Critical information areas have higher brightness and contrast for maximum visibility, while secondary information areas have lower intensity. The display adjusts local properties based on the importance and type of information presented.
3Quantity of substance
If the button size is small, then the screen can display more information, but the ease of operation is reduced
Solution Approach 1:
The button size dynamically changes based on detected hand proximity. When the driver's hand approaches the steering wheel controls, buttons automatically enlarge to facilitate easy operation. When the hand is not present, buttons return to their normal smaller size, allowing more elements to be displayed.
Solution Approach 2:
The system changes the size parameter of display elements based on operational context. Buttons transition between different size states (small for display density, large for operation) depending on whether the driver intends to interact with them.
4Illumination intensity
If the transparency is high, then the display is more visible, but the glare and distraction to the driver increases
Solution Approach 1:
The display transparency and brightness dynamically adjust based on ambient light conditions and driving speed. At high speeds, the display becomes less transparent and dimmer to reduce distraction. At lower speeds or when parked, the display can be more transparent and brighter for better visibility.
Solution Approach 2:
The system changes optical parameters (transparency, brightness, contrast) of the display based on operational context. These parameters are adjusted in real-time to balance visibility needs with driver safety and minimize distraction.

AI summary
A vehicle information display apparatus may include: an input unit configured to receive driving speed information of a vehicle; a memory configured to store a program for performing speed-based mobile phone screen control by using the driving speed information of the vehicle; and a processor configured to execute the program. The processor may adjust the transparency or button size of the mobile phone screen according to the driving speed of the vehicle.
