Vehicle AVN Contact Priority Management for Multi-Terminal Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Audio, Video, Navigation (AVN) systems in vehicles are limited in the number of terminals they can register due to data capacity constraints, leading to inefficiencies in managing contact information and providing hands-free functions.
Innovation Solution
A system and method that prioritize contact information management based on terminal usage history, utilizing a communication unit, connection confirming unit, priority calculating unit, and contact information renewing unit to communicate with terminals, confirm connections, calculate priorities, and manage contact information storage within the AVN system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the AVN system stores all contact information from all terminals, then complete contact information is available, but the system complexity and management difficulty increase
Solution Approach 1:
The patent applies local quality by differentiating the treatment of contact information based on terminal priority. Instead of uniform storage of all contact information, the system assigns different storage qualities to different terminals. High-priority terminals receive full contact information storage, while low-priority terminals have their contact information excluded. This creates a non-uniform, localized quality approach that reduces overall system complexity while maintaining essential contact information completeness.
2Productivity
If the system prioritizes contact information from specific terminals, then data retrieval efficiency improves, but the system requires additional priority calculation mechanisms
Solution Approach 1:
The patent implements preliminary action by pre-calculating and storing priority levels for each terminal before actual data retrieval operations. The system continuously monitors terminal connections, usage patterns, and interaction history to establish priority rankings in advance. When contact information needs to be retrieved or stored, the system simply references the pre-established priority levels rather than performing complex real-time calculations. This preliminary prioritization significantly improves data retrieval efficiency while minimizing the computational complexity during actual operations.

AI summary
A system and a method of managing contact information of a terminal recognized by a vehicle include: a communication unit, which communicates with one or more terminals located in a vehicle and recognizes the terminal, and which receives information stored in the recognized terminal; a connection confirming unit which confirms a function, to which the terminal recognized through the communication unit is connected through communication, among the functions provided by an Audio, Video, and Navigation (AVN) system of the vehicle; a priority calculating unit, which calculates a priority of the terminal with respect to other terminals according to the connection between the terminal confirmed by the connection confirming unit and the function provided by the AVN system and generates priority list information for maintaining contact information stored in the terminal; and a contact information renewing unit, which downloads and stores the contact information stored in the terminal in a linked database according to the priority list information generated by the priority calculating unit or deletes the contact information stored in the database.
