In-Vehicle Display Resizing Based on Driving Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increase in size of center information displays (CIDs) in vehicles disperses a driver's gaze and makes it difficult to perform accurate inputs, increasing the risk of safety issues and reducing user convenience.
Innovation Solution
An electronic device and control method that adjusts the display size and input means based on driving context, using a processor to determine IVI levels and change the UI accordingly, shifting information and inputs between different displays to minimize driver distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the size of the center information display (CID) is increased to provide more various pieces of information, then the information provision capability is improved, but the driver's gaze is dispersed and safety problems may occur
Solution Approach 1:
The CID dynamically adjusts its display size based on the vehicle's driving state. When the vehicle is stationary or moving at low speed, the CID displays at full size to provide comprehensive information. When the vehicle is moving at high speed, the CID reduces its display size or switches to a different display mode to minimize driver distraction and maintain safety.
2Adaptability or versatility
If the size of the CID is increased to provide more functions, then the functionality is improved, but the user's movement for input is increased and accurate input becomes difficult
Solution Approach 1:
The system dynamically adjusts the CID size based on vehicle speed. At low speeds where precise input is needed, the CID is displayed at full size allowing easy access to all functions. At high speeds, the CID size is reduced or alternative input methods are prioritized to simplify operations and maintain input accuracy.
3Adaptability or versatility
If the CID is positioned at the center of the dashboard to provide infotainment, then the infotainment function is improved, but the driver's attention is dispersed compared to the cluster positioned in the gaze direction
Solution Approach 1:
The CID's display characteristics dynamically change based on vehicle speed. At low speeds, the CID can be fully utilized for infotainment purposes. At high speeds, the system reduces the CID's prominence or switches to displaying only essential driving information, thereby maintaining driver attention while preserving infotainment functionality when appropriate.

AI summary
According to an embodiment disclosed in this specification, an electronic device may be configured to obtain driving information of the vehicle, the driving information including transmission state information of the vehicle and information for an autonomous driving function; when the transmission state information indicates a position other than drive, control the size of the exposed region of the first display to be a first size, using the driving unit; when the transmission state information indicates drive and the driving information indicates that the autonomous driving function is enabled, control the exposed region of the first display to be a second size that is less than the first size, using the driving unit; and when the transmission state information indicates drive and the driving information indicates that the autonomous driving function is disabled, control the exposed region of the first display to be less than the second size, using the driving unit.
