IVI Management Module Decouples Control from Hardware
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle infotainment (IVI) systems lack flexibility in controlling IVI components, limiting user experience and system expansion due to tight coupling between application programs and hardware devices.
Innovation Solution
An IVI apparatus with a management module that obtains and sends component information to a terminal device, allowing it to communicate with IVI components, reducing coupling and enhancing flexibility through open protocol standards and connection modules for network access and charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If application programs and hardware devices are tightly coupled in the IVI system, then the system can provide stable and reliable IVI services, but the flexibility and ease of system expansion are reduced
Solution Approach 1:
The patent segments the IVI system into independent components: terminal devices, IVI components, and an IVI apparatus. The terminal device runs application programs independently and communicates with IVI components through the IVI apparatus, which manages component information and establishes connections. This segmentation decouples the tight relationship between application programs and hardware devices, allowing independent updates and expansions of each component while maintaining system stability.
2Device complexity
If the IVI system uses built-in application programs and fixed invocation relationships, then the system structure is simple and reliable, but the ease of operation and user control are limited
Solution Approach 1:
The IVI apparatus serves as an intermediary between terminal devices and IVI components. It obtains component information from IVI components, manages this information centrally, and facilitates communication between terminal devices and IVI components based on user requests. This intermediary structure allows users to control IVI components through their terminal devices with simple operations, while the IVI apparatus handles the complex coordination and connection management in the background.
3Reliability
If the IVI system maintains fixed invocation relationships between application programs and hardware devices, then the system is reliable and stable, but the ease of manufacture and system upgrade are difficult
Solution Approach 1:
The patent implements dynamic invocation relationships where the IVI apparatus obtains component information from IVI components and matches them with terminal devices based on service requests in real-time. The invocation relationship is not fixed but dynamically established based on current system state and user needs. This allows the system to be upgraded by simply adding new IVI components or terminal devices without restructuring the entire system, while maintaining stability through the standardized communication framework managed by the IVI apparatus.
