Projected Interface Function Conflict Handling in Vehicle Head Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle systems face function conflicts when projecting interfaces from terminal devices, such as head units, leading to impaired user experience due to simultaneous operation of conflicting functions using shared hardware modules like microphones and speakers.
Innovation Solution
A method and apparatus that enable devices to share status information of their functions, allowing for conflict resolution by processing overlapping functions, such as stopping one function or using separate hardware modules, to ensure seamless operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the interface of the first device is projected to the second device, then the user can use functions of the first device on the second device, but function conflicts occur when both devices attempt to use shared hardware modules simultaneously
Solution Approach 1:
The patent applies preliminary action by having the first device send status information of its functions to the second device before actual function execution occurs. This allows the second device to advance-know the working states of functions on the first device and proactively avoid conflicts by selecting appropriate processing manners (such as interrupting or skipping) before the conflicting functions are executed, thereby ensuring reliable function execution while maintaining adaptability
2Reliability
If the second device uses its original function while the first device projects a conflicting function, then the second device maintains its native functionality, but the user cannot normally use the projected function
Solution Approach 1:
The patent applies dynamics by making the processing manner of the second device adaptive and changeable based on real-time status information. Instead of a fixed approach, the second device dynamically selects from multiple processing manners (interrupt, skip, or concurrent execution) depending on the current working states of both devices, allowing it to maintain native function reliability while ensuring projected function usability through flexible adjustment
3Reliability
If status information is shared between devices, then function conflicts can be detected and processed, but the system complexity increases
Solution Approach 1:
The patent applies the taking out principle by extracting only the necessary status information (working states of specific functions) from the first device and transmitting it to the second device, rather than sharing all possible data. This selective extraction enables conflict detection and processing capability while minimizing information synchronization complexity by focusing only on the critical status parameters needed for conflict avoidance

AI summary
This disclosure provides function conflict processing methods and apparatuses. In an implementation, a method includes: receiving, from a first device and by a second device, projection data and first status information of a first function of the first device, wherein the first status information indicates a working status of the first function of the first device, and in response to determining that: (1) the first status information indicates that the first function of the first device is in a working state and (2) a first function of the second device is in a working state, processing, by the second device, a conflict of the first function.
