Solution Overview

Problem

Current vehicle-to-everything (V2X) communication systems have limited effectiveness due to the need for vehicles to be within a specific communication range to transmit and receive data, restricting their application to only certain scenarios.

Innovation Solution

Deploying unmanned aerial vehicles (UAVs) equipped with sensors and communication interfaces to assist V2X communications by transmitting and receiving information about road conditions and vehicle data, using cellular V2X and dedicated short-range communications, and integrating with technologies like GPS, visual light communications, and radar to extend communication range and facilitate data exchange.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If V2X communication is implemented using traditional cellular or WLAN systems, then data transmission reliability is improved, but communication range is limited and application scenarios are restricted

Engineering Contradiction:
Improvedata packet delivery success rateVSAvoidcommunication range
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

The patent introduces UAVs as intermediary nodes between vehicles and the network infrastructure. These UAVs equipped with V2X communication modules act as mobile relays, receiving data from vehicles and forwarding it to distant targets, thereby extending the effective communication range beyond traditional cellular or WLAN limitations while maintaining reliable data transmission through established protocols

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transitions from ground-based V2X communication to three-dimensional aerial communication by deploying UAVs in the air space above roadways. This spatial dimensionality change allows communication signals to propagate over longer distances and overcome ground obstacles, effectively expanding the communication coverage area without sacrificing transmission reliability

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If V2X communication is limited to within a specific communication range, then system complexity is reduced, but road safety and traffic efficiency are compromised

Engineering Contradiction:
Improvecommunication system complexityVSAvoidroad safety warning effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent employs dynamically deployable UAVs that can be positioned and repositioned in real-time based on traffic conditions and safety requirements. This dynamic deployment allows the system to extend safety warning coverage to areas beyond fixed communication ranges without requiring a permanently complex infrastructure, as UAVs are activated only when and where needed

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If UAVs are deployed to extend communication range, then application scenarios are expanded, but device complexity and deployment difficulty increase

Engineering Contradiction:
ImproveV2X application scenariosVSAvoidUAV deployment system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs UAVs with multi-functional capabilities including V2X communication modules, sensor suites for environmental perception, and integrated navigation systems. This universality allows a single UAV platform to handle multiple V2X application scenarios such as collision warning, traffic flow optimization, and infrastructure monitoring, thereby expanding application versatility without proportionally increasing system complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Techniques are described herein for conducting traffic and road operations using unmanned aerial vehicle (UAV) assisted vehicle-to-everything (V2X) communications. The UAVs can be deployed at various locations and can be operatively connected to a cell site, a mobile edge computing (MEC) server, and/or a V2X sensor. The UAVs, upon detecting an oncoming vehicle from a target location traveling towards one or more autonomous vehicles (AVs), can directly communicate with the one or more AVs to alert the AVs of the approaching oncoming vehicle. If the UAVs cannot communicate with the AVs, the UAVs can handover messages to other UAVs that can communicate with the AVs. The UAVs can also transport messages to a cell site and/or a V2X sensor to broadcast messages to the one or more AVs. Cell sites can also transmit messages to broadcast the messages to the AVs within respective coverage areas.
