Dynamic Communication Module Selection for Vehicle Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle communication systems face instability due to the inability to dynamically select the most appropriate communication module based on changing communication conditions such as signal strength, speed, and availability across different regions.
Innovation Solution
A communication apparatus that evaluates and selects between in-vehicle and external communication modules using a selection table updated by a server based on the vehicle's location, considering criteria like communication cost, speed, and availability, ensuring optimal module selection for stable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plurality of communication modules are available for selection, then communication flexibility and adaptability are improved, but communication stability deteriorates due to difficulty in selecting the most appropriate module dynamically
Solution Approach 1:
The patent implements dynamic selection of communication modules based on real-time evaluation of communication conditions. The system continuously monitors signal strength, communication speed, and availability for each module type (in-vehicle and external modules) and dynamically switches between them according to current conditions, transforming the static module selection into a dynamic adaptive process that maintains both flexibility and stability
Solution Approach 2:
The patent establishes a feedback mechanism where the system evaluates communication conditions for each available module, compares them against selection criteria, and uses this feedback information to determine optimal module selection. This closed-loop control ensures that the system responds to changing conditions while maintaining stable communication through informed decision-making
2Productivity
If communication modules are selected based on multiple criteria (cost, speed, availability), then communication efficiency is improved, but system complexity increases due to evaluation and selection processes
Solution Approach 1:
The patent segments the complex selection process into distinct evaluation components: signal strength evaluation, communication speed evaluation, availability assessment, and cost consideration. Each criterion is evaluated separately and then integrated through a structured selection table, breaking down the complex decision-making into manageable segments that improve efficiency without overwhelming system complexity
Solution Approach 2:
The patent performs preliminary evaluation of communication conditions for each module type before actual communication occurs. By pre-assessing signal strength, speed, availability, and cost factors and storing this information in a selection table, the system prepares advance guidance for module selection, reducing real-time decision complexity while maintaining high communication efficiency

AI summary
A communication apparatus that can communicate with a public communication network by using an in-vehicle communication module permanently installed in a vehicle or one or more external communication modules not installed permanently in the vehicle. The communication apparatus includes: a memory unit configured to store a selection table recording a criterion for selecting a communication module to be used for the communication; and a control unit configured to evaluate a plurality of the communication modules and acquire an evaluation result; and to select a communication module to be used for communication according to the evaluation result and the selection table.
