Vehicle Display Control Using Smartphone Position-Based Auxiliary Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles face limitations in displaying driving information due to the small screen size of In-Vehicle Infotainment (IVI) devices, necessitating a solution to enhance information display through user terminals like smartphones.
Innovation Solution
A vehicle system that includes a holder, communication interface, and controller to identify the position of a user terminal, determine auxiliary information based on its position, and transmit it to the terminal, prioritizing information display based on tilt and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If driving information is displayed only on the IVI device, then the system is simple, but the display area is limited due to the small screen size
Solution Approach 1:
The patent combines the IVI device display with the user terminal display to create an extended display system. The controller integrates information from both displays, allowing driving information to be shown across multiple screens including the smartphone or tablet held by the user, thereby significantly increasing the effective display area while maintaining coordinated control through a unified system
Solution Approach 2:
The controller acts as an intermediary between the IVI device and the user terminal. It receives information from the IVI device, processes it according to preset rules, and transmits selected information to the user terminal for display. This mediator approach enables extended display functionality while keeping the system architecture manageable through centralized control logic
2Loss of information
If all vehicle operating information is transmitted to the user terminal, then complete information is provided, but the user terminal becomes overloaded and difficult to manage
Solution Approach 1:
The controller extracts and transmits only the necessary auxiliary information to the user terminal, rather than sending all vehicle operating information. It identifies key information elements based on preset criteria such as driving state, vehicle speed, and navigation status, filtering out redundant data. This extraction approach ensures the user terminal receives sufficient information for enhanced display without being overloaded with unnecessary data
Solution Approach 2:
Different types of information are transmitted to different display locations based on their importance and relevance. Critical driving information is prioritized for transmission to the user terminal, while less important information remains on the IVI device. This localized information distribution optimizes both information completeness and user terminal manageability by tailoring the information sent to each display's specific needs

AI summary
A vehicle includes at least one holder, a communication interface configured to communicate with a user terminal, a user interface device configured to visualize and output vehicle operating information, and a controller configured to, in response to the user terminal being mounted on the at least one holder, identify a position of the user terminal, determine auxiliary information to be displayed on the user terminal from the vehicle operating information based on the position of the user terminal, and control the communication interface to transmit the auxiliary information to the user terminal.
