Mobile Device Proxy for Legacy Vehicle V2X Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy vehicles without V2X capabilities cannot fully participate in vehicle-to-everything (V2X) communications, leading to suboptimal involvement in safety maneuvers and lack of situational awareness, as they cannot receive or process relevant V2X messages, resulting in a high processing burden for proxy devices that must filter through irrelevant data.
Innovation Solution
A mobile device acts as a proxy for legacy vehicles, determining temporal colocation and relevance of V2X messages, filtering out irrelevant data to provide driving assistance information, thereby minimizing processing load and enhancing driver awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile device acts as a proxy for legacy vehicles to enable V2X communication, then legacy vehicles can participate in V2X networks and receive driving assistance information, but the processing burden on the mobile device increases due to filtering through irrelevant data
Solution Approach 1:
The mobile device determines temporal colocation with the vehicle before processing V2X messages. This preliminary filtering action ensures that only messages relevant to the specific vehicle are processed, reducing the processing burden while enabling V2X network participation for legacy vehicles
Solution Approach 2:
The system filters V2X messages based on local relevance to the specific vehicle-proxy relationship. By determining temporal colocation and message relevance before processing, the system applies local quality filtering to reduce unnecessary processing while maintaining V2X adaptability
2Productivity
If the mobile device filters V2X messages based on temporal colocation and relevance, then processing efficiency improves, but the complexity of determining colocation and relevance increases
Solution Approach 1:
The mobile device serves as an intermediary between V2X communication infrastructure and legacy vehicles. It determines temporal colocation and message relevance as intermediate filtering steps, improving processing efficiency while managing complexity through structured determination protocols
3Reliability
If legacy vehicles without V2X capabilities receive driving assistance information through proxy devices, then driver awareness and safety improve, but the reliability of information delivery may be compromised due to data filtering
Solution Approach 1:
The mobile device performs preliminary determination of temporal colocation and message relevance before filtering and delivering information. This ensures that only accurately relevant messages are delivered to legacy vehicle drivers, maintaining information delivery reliability while reducing data filtering losses through precise preliminary filtering criteria

AI summary
Techniques described herein include utilizing a mobile device as a proxy receiver for a vehicle such that a driver of the vehicle can be presented driving assistance information based on messages received by the mobile device. The mobile device can determine that it is temporally located with the vehicle. If so, the mobile device can be configured to receive messages from other entities (e.g., vehicles, roadside units, traffic signals, and the like) in a vehicle-to-everything network. On reception, the mobile device may determine whether a received data message is relevant to the vehicle. In response to determining that the data message is, in fact, relevant to the vehicle, the mobile device may provide driving assistance information that is generated based at least in part on the information provided in the received data message.
