Mobile Device Proxy for Legacy Vehicle V2X Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy vehicles lack the capability to transmit and receive V2X messages, limiting their participation in vehicle-to-everything communication and reducing their ability to benefit from shared interactions and environmental awareness.
Innovation Solution
A mobile device acts as a proxy for legacy vehicles, obtaining transmission credentials and processing V2X data on their behalf, enabling them to participate in V2X communication and share information with other V2X-capable vehicles and infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If legacy vehicles are excluded from V2X communication due to lack of transmission capability, then V2X network complexity is reduced, but legacy vehicle participation and safety are worsened
Solution Approach 1:
A mobile device acts as an intermediary between legacy vehicles and the V2X network. The mobile device obtains transmission credentials and transmits V2X messages on behalf of the legacy vehicle, enabling participation without requiring modifications to the legacy vehicle itself. This resolves the contradiction by maintaining network simplicity while achieving legacy vehicle inclusion through a mediating entity.
2Adaptability or versatility
If legacy vehicles are equipped with V2X communication components, then legacy vehicle participation is improved, but device complexity and cost are worsened
Solution Approach 1:
The mobile device serves as an external intermediary that handles all V2X communication functions. Instead of adding communication components to the legacy vehicle, the mobile device independently manages credential acquisition and message transmission, thereby achieving legacy vehicle participation without increasing vehicle device complexity.
Solution Approach 2:
The mobile device creates a functional copy of V2X communication capabilities that the legacy vehicle lacks. By obtaining transmission credentials and transmitting messages on behalf of the legacy vehicle, the mobile device replicates the communication functions that would otherwise require dedicated hardware in the legacy vehicle.
3Adaptability or versatility
If a mobile device acts as proxy for legacy vehicles, then legacy vehicle participation is improved, but transmission credential security management is worsened
Solution Approach 1:
The system implements feedback mechanisms where the mobile device monitors and manages transmission credentials dynamically. The mobile device obtains credentials from credential authorities and uses them appropriately for legacy vehicle communication, with the ability to revoke or update credentials based on security conditions, thereby maintaining security while enabling participation.

AI summary
Techniques described herein include utilizing a mobile device as a proxy receiver and/or transmitter for a vehicle in a V2X network. In some embodiments, the mobile device associated mobile device capabilities may be configured to obtain vehicle capabilities and store such data in memory at the mobile device. The mobile device may obtain any suitable combination of a reception credential and one or more transmission credentials. In some embodiments, the one or more transmission credentials may be generated by a credential authority based at least in part on determining that the vehicle capabilities and mobile device capabilities indicate that the sensor(s) and/or processing resources of the vehicle and/or mobile device meet transmission requirement thresholds for the network. The mobile device may subsequently transmit any suitable data message on behalf of the vehicle using at least one of the transmission credentials.
