Mobile ITS Station Software Update via V2X P2P
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for software updates in mobile ITS stations face challenges when the station is in motion, particularly at high speeds, as they often require cellular communication or manual intervention, making consistent updates difficult.
Innovation Solution
A method for mobile ITS stations to perform software updates via V2X communication by identifying a neighbor station with an updatable software version, requesting and receiving the update file through a Peer-to-Peer network using a communication interface like DSRC, allowing for direct vehicle-to-vehicle communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cellular communication (C-V2X) or infrastructure-based V2I communication is used for software updates, then update reliability is improved, but the system cannot consistently update while the mobile ITS station is being driven at high speed
Solution Approach 1:
The patent introduces a Peer-to-Peer communication interface as an intermediary mechanism that enables direct software update file transmission between mobile ITS stations without requiring cellular networks or infrastructure. This allows updates to occur during high-speed driving by establishing direct communication links between vehicles in proximity, resolving the contradiction between reliable updates and adaptability during motion.
Solution Approach 2:
The system enables mobile ITS stations to perform self-updates by autonomously identifying neighboring stations with update files, initiating download requests, and receiving update packages through P2P communication. This self-service capability allows updates to proceed during high-speed driving without manual intervention or dependency on external infrastructure, simultaneously achieving reliability and adaptability.
2Manufacturing precision
If manual update intervention is required, then update control precision is improved, but productivity and ease of operation deteriorate
Solution Approach 1:
The system automatically identifies neighboring mobile ITS stations possessing software update files, initiates download requests without user intervention, and completes the update process autonomously. This eliminates manual intervention requirements while maintaining precise update control through automated version verification and file integrity checks, thereby improving both productivity and ease of operation.
Solution Approach 2:
The system implements feedback mechanisms where mobile ITS stations broadcast their software version information and update file availability to neighboring stations. This feedback enables automatic identification of suitable update sources and verification of update requirements, ensuring precise update control while enabling efficient automated execution without manual intervention.
3Reliability
If infrastructure-based V2I communication is used for updates, then update reliability is improved, but device complexity and dependency on external infrastructure increase
Solution Approach 1:
The patent extracts the software update function from dependency on external cellular networks and infrastructure by implementing direct P2P communication between mobile ITS stations. This removes the infrastructure dependency while maintaining update reliability through direct vehicle-to-vehicle file transmission, thereby reducing device complexity and external dependencies.
Solution Approach 2:
The P2P communication interface serves multiple functions: it enables software update file transmission, broadcasts software version information, and facilitates direct peer-to-peer communication between vehicles. This multi-functionality eliminates the need for separate infrastructure-based update systems, reducing overall system complexity while maintaining reliable update capabilities.

AI summary
A method of controlling a first mobile Intelligent Transport System (ITS) station. The method includes identifying a second mobile ITS station having a software version updatable on the first mobile ITS station based on receiving a message from at least one neighbor mobile ITS station through a first communication interface; making a request for a software update file for the updatable software version to the second mobile ITS station through the first communication interface; and receiving the software update file from the second mobile ITS station while a connection to the second mobile ITS station is maintained through the first communication interface.
