Vehicle Display Exposure Control for Driving Context Input Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing size of center information displays (CIDs) in vehicles disperses a driver's gaze, potentially leading to safety issues and difficulties in entering accurate inputs while driving.
Innovation Solution
A method and device for controlling a display in a vehicle based on driving context, where the size of the exposed region of the display is adjusted depending on the transmission state and autonomous driving function status, to minimize driver distraction and facilitate accurate input.
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 quantity of information provided is improved, but the driver's gaze becomes dispersed and safety problems may occur
Solution Approach 1:
The CID is designed with adjustable size that dynamically changes based on driving conditions. The display size is reduced when the vehicle is in motion and expanded when parked, allowing the system to adapt to different operational states and minimize gaze dispersion during driving while maximizing information provision when stationary
Solution Approach 2:
The physical parameter of display size is changed based on transmission state. The system detects whether the vehicle is in drive mode or parked mode and adjusts the CID size accordingly, transforming the display from a large static structure to a dynamically sized interface that responds to operational context
2Adaptability or versatility
If the size of the CID is increased to provide more functions, then the versatility of the system is improved, but the user's movement for input increases and accurate input becomes difficult
Solution Approach 1:
The CID size dynamically adapts to driving conditions, being reduced during motion to minimize the movement distance required for touch inputs. This dynamic adjustment ensures that frequently used controls remain within easy reach while the system maintains full functionality through software-based adaptability
Solution Approach 2:
The system achieves versatility not through physical expansion but through software-based multi-functionality. The reduced-size display during driving provides essential controls and information, while the full functionality is available when parked, allowing one physical structure to serve multiple operational contexts

AI summary
Methods and devices are provided for use in a vehicle. Driving information of the vehicle is obtained. The driving information includes transmission state information of the vehicle and information for an autonomous driving function. When the transmission state information indicates a position other than drive, a size of an exposed region of a first display is controlled to be a first size. When the transmission state information indicates drive and the driving information indicates that the autonomous driving function is enabled, the exposed region of the first display is controlled to be a second size that is less than the first size. When the transmission state information indicates drive and the driving information indicates that the autonomous driving function is disabled, the exposed region of the first display is controlled to be less than the second size.
