Vehicle Mobile Terminal Identification Information Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-vehicle communication systems face instability and misuse of vehicle information, leading to trust issues and ineffective safe driving support services due to periodic updates of vehicle IDs and identification information, which can result in unstable operations and potential misuse of information for purposes other than safe driving support.
Innovation Solution
A mobile terminal determines the necessity of transmission control for mobile device information based on the possibility of misuse and the magnitude of adverse influence on the service, using multiple identification information and suspending or updating information to prevent misuse without affecting the service's stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If vehicle ID is updated periodically to prevent information misuse, then security against misuse is improved, but service stability deteriorates because receiving vehicles can no longer identify the own vehicle
Solution Approach 1:
The patent segments identification information into multiple types (first identification information for anti-m misuse and second identification information for service identification). This segmentation allows each type to serve its specific function independently, resolving the contradiction between preventing misuse and maintaining service stability.
Solution Approach 2:
The patent applies different identification information for different purposes: first identification information is used specifically for preventing misuse by tracking vehicles, while second identification information is used for stable service operations. This local differentiation of function resolves the contradiction by optimizing each identification type for its specific role.
2Object-affected harmful factors
If identification information is updated immediately when exiting proximate condition, then security is improved, but service stability deteriorates due to potential identification changes during active communication
Solution Approach 1:
The patent implements dynamic control of identification information updates based on the proximate condition state. Updates are suppressed during proximate conditions to maintain stability, and enabled when exiting proximate conditions to improve security. This dynamic adjustment resolves the contradiction between security and stability.
Solution Approach 2:
The patent determines in advance whether updating identification information is appropriate by evaluating the proximate condition before performing the update. This preliminary assessment prevents unstable identification changes during active communication while ensuring security updates occur when safe, resolving the contradiction.
3Object-affected harmful factors
If multiple identification information are maintained for different purposes, then security against misuse is improved, but device complexity increases
Solution Approach 1:
The patent segments identification information into distinct types with specific functions, making the complexity manageable through clear functional separation. First identification information handles anti-m tracking prevention while second handles service identification, reducing the cognitive and operational complexity compared to a single undifferentiated system.

AI summary
If identification information is updated periodically, there is such a problem that when another vehicle is receiving driving support based on transmitted identification information of an own vehicle, if the identification information of the own vehicle is updated, the operation of driving support using the identification information becomes unstable because another vehicle can no longer identify the own vehicle.A mobile terminal mounted on a vehicle determines whether or not transmission control of identification information is necessary after determining the possibility of identification information misuse, determining the effect by controlling transmission of identification information, and determining the magnitude of adverse influence on the safe driving support service.
