Vehicle Head Unit Dynamic UI Configuration via Mobile App Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for processing mobile terminal applications on vehicle head units, such as mirroring, fail to provide a flexible and user-friendly interface, making it difficult for drivers to focus on driving and do not accommodate various applications efficiently, especially without layout information.
Innovation Solution
A method that dynamically configures the user interface of a vehicle head unit by acquiring information on executable applications from a mobile terminal, selecting an appropriate template based on the applications and driving state, and displaying them using a specific mode, including full, minimized, or floating display modes, to optimize the user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mirroring method is used to display mobile terminal screen on head unit, then the mobile terminal environment is grafted onto the vehicle head unit, but the screen becomes complicated and drivers cannot concentrate on driving
Solution Approach 1:
The patent extracts only the necessary application information from the mobile terminal rather than mirroring the entire screen. The head unit acquires specific application data (type, name, icon) and displays it through a simplified template interface, removing unnecessary screen elements while preserving application functionality.
Solution Approach 2:
The patent applies different display templates based on the specific application being displayed. Each application type (music, navigation, phone) receives a customized display layout optimized for its function, rather than using a uniform mirroring approach. This localizes the display quality to match the specific application requirements.
2Adaptability or versatility
If multiple applications are displayed on the head unit, then more functionality is provided, but the interface becomes more complex and difficult to manage
Solution Approach 1:
The patent creates a universal template system that can accommodate multiple different application types through a single standardized interface framework. The templates are designed to be multi-functional, handling music players, navigation apps, phone applications, and other types through common display patterns and layout structures.
Solution Approach 2:
The patent segments the display interface into modular templates that can be independently selected and configured. Each template represents a discrete functional unit that can be activated based on the running application, allowing the interface to be divided into manageable, context-specific sections rather than a monolithic complex display.
3Adaptability or versatility
If the head unit displays applications without layout information, then compatibility is maintained, but the screen configuration cannot be optimized for different applications and driving states
Solution Approach 1:
The patent prepares multiple display templates in advance, each optimized for specific application types and driving conditions. These templates are pre-configured with appropriate layouts, icon arrangements, and display parameters before the application runs, allowing the head unit to quickly select and apply the most suitable template without real-time optimization complexity.
Solution Approach 2:
The patent changes display parameters (layout, icon size, information hierarchy) based on the specific application type and driving state. The system adjusts these parameters dynamically by selecting from pre-prepared template variations, enabling optimization without requiring complex real-time layout generation.

AI summary
The present invention relates to a method for configuring a user interface of a head unit of a vehicle by using a mobile terminal. The method includes steps of: (a) allowing the head unit of the vehicle to acquire information on at least one application stored at an executable state in the mobile terminal, if the mobile terminal is connected to the head unit; (b) allowing the head unit to decide a specific template interoperable with the application among multiple templates stored in the head unit by referring to the acquired information on the application; and (c) deciding a display mode of the specific template by referring to at least one piece of information on the number of acquired application and the driving state of the vehicle and displaying the acquired application on a screen of the head unit by using the decided display mode of the specific template.
