Vehicle Communication via Stored Road Data in RSU-Free Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle-to-Infrastructure (V2I) communication systems face challenges in areas without Road-Side Units (RSUs), as vehicles rely on RSUs for critical information about road conditions and safety, which can be limited by RSU installation constraints such as high costs, difficult terrain, and poor connectivity.
Innovation Solution
Vehicles are equipped with controllers that can gather and store data about vehicle events at locations without RSUs and communicate directly with other vehicles via wireless communication, allowing them to transmit and update information about road conditions, enabling vehicles to adjust their operating parameters proactively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If V2I communication relies on RSUs for critical road condition information, then information accuracy is improved, but system coverage and accessibility deteriorate in areas without RSUs
Solution Approach 1:
The patent introduces vehicles as intermediary nodes that collect, store, and relay road condition information in areas without RSUs. When a vehicle encounters road conditions, it stores this information locally and transmits it to other vehicles through V2V communication, acting as a mobile intermediary that bridges the information gap in RSU-free zones.
Solution Approach 2:
The patent implements a mechanism where vehicles create copies of road condition information gathered from RSUs or directly observed conditions. These copied information packets are stored in vehicle memory and distributed to other vehicles, enabling information replication and dissemination without requiring physical RSU infrastructure at every location.
2Loss of information
If RSUs are installed to provide comprehensive V2I communication coverage, then information availability is improved, but infrastructure cost and complexity increase
Solution Approach 1:
The patent enables vehicles to serve themselves by equipping them with onboard units that can independently gather, store, and share road condition information. This self-service capability reduces dependency on centralized RSU infrastructure, allowing the system to maintain information availability through distributed vehicle-based resources rather than extensive fixed infrastructure.
Solution Approach 2:
The patent makes vehicles multi-functional by enabling them to perform multiple roles: they remain their primary transportation function while simultaneously acting as mobile information collectors, storage units, and communication nodes. This universality eliminates the need for dedicated RSU infrastructure at every location, as vehicles fulfill multiple information dissemination functions.
3Adaptability or versatility
If vehicles store road condition data locally without RSUs, then system independence is improved, but data transmission reliability deteriorates in RSU-free zones
Solution Approach 1:
The patent implements preliminary action by having vehicles proactively gather and store road condition information in their memory before needing to transmit it. When road conditions are detected or RSU information is received, vehicles pre-store these data packets, ensuring that information is readily available for immediate transmission to other vehicles without requiring real-time RSU connectivity.
Solution Approach 2:
The patent provides beforehand cushioning by creating redundant information storage across multiple vehicles. Instead of relying on a single transmission path from RSUs, the system distributes information copies across the vehicle fleet in advance, cushioning against potential transmission failures or RSU unavailability by having multiple independent information sources ready to relay data.

AI summary
Methods and systems are proposed for a communication network. In one example, a system for a vehicle comprises a controller of the vehicle comprising instructions stored in memory thereof that when executed enable the controller to gather data related to a vehicle event at a location and store the data in memory in response to the location being free of a road-side unit (RSU), where the controller is further configured to establish a vehicle-to-infrastructure network in wireless communication with the vehicle at a second location different from the location.
