Vehicle-to-Infrastructure Communication Control Using Directional Short-Wave Antennas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-everything (V2X) communication systems face challenges in maintaining data transmission integrity due to blockages and coverage area limitations, which can impede the flow of critical information such as weather conditions and traffic updates between vehicles and infrastructure.
Innovation Solution
The system employs a vehicle computer and infrastructure computer that utilize directional short-wave antennas and phased-array antennas to establish and maintain communication by determining optimal transmission paths and adjusting antenna directions based on vehicle location, trajectory, and blockages, allowing for the transmission of data even when direct lines are obstructed through secondary vehicle forwarding.

Engineering Contradiction Analysis
1Reliability
If V2X communication systems use traditional wireless communication networks, then data can be transmitted between vehicles and infrastructure, but data transmission is prevented or impaired when blockages occur or coverage area is limited
Solution Approach 1:
The patent introduces intermediary relay vehicles that forward data between infrastructure elements and target vehicles. When direct communication is blocked or unavailable, relay vehicles act as mediators to transmit data through alternative paths, ensuring continuous communication despite blockages or coverage limitations.
Solution Approach 2:
The system transitions from traditional two-dimensional ground-based wireless communication to three-dimensional short-wave radio communication utilizing aerial/vertical paths. This enables data transmission through the atmosphere rather than being constrained to ground-level line-of-sight, overcoming blockages and expanding coverage areas.
2Reliability
If the system uses directional short-wave antennas with phased-array technology, then communication reliability improves in obstructed environments, but device complexity increases
Solution Approach 1:
The patent employs dynamic beamforming and electronic steering of phased-array antennas to adaptively direct communication paths based on real-time vehicle locations, trajectories, and detected blockages. This dynamic adjustment enables the system to overcome obstacles and maintain reliable communication without requiring physical reconfiguration.
Solution Approach 2:
The system performs preliminary actions by pre-establishing communication parameters, coverage areas, and relay vehicle lists before actual data transmission occurs. Infrastructure elements broadcast their locations and coverage information in advance, allowing vehicles to proactively select optimal communication paths and relay vehicles before blockages occur.

AI summary
A vehicle computer comprises a processor and a memory. The memory stores instructions executable by the processor to receive a location of a first stationary directional short-wave antenna, to determine a line from a vehicle location to the location of the first stationary antenna, to transmit a short-wave request message to the first stationary short-wave antenna based on the determined line, the message including vehicle data, and upon receiving a short-wave acknowledgment message from the first stationary short-wave antenna, to transmit a second short-wave message including vehicle data.
