Parallel Vehicle V2V Communication Channels for Security and Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle communication systems are vulnerable to man-in-the-middle attacks and suffer from intermittent communication, leading to potential safety issues due to lack of redundancy in wireless channels, especially in challenging RF environments, and limitations in accurately tracking vehicle locations, particularly in areas where GPS signals are weak or unreliable.
Innovation Solution
Implementing a method that activates multiple wireless communication channels in parallel between vehicles, operating at different radio carrier frequencies, to transmit common information and subsequently deactivate them, while also using a vehicle-to-device key exchange system to securely authenticate communication and monitor vehicle locations across intersections, using a combination of GPS and route circuits for location determination.

Engineering Contradiction Analysis
1Reliability
If a single wireless communication channel is used between vehicles, then device complexity is reduced, but communication reliability deteriorates due to lack of redundancy in challenging RF environments
Solution Approach 1:
The communication system is segmented into multiple independent wireless channels operating at different radio carrier frequencies. Each channel functions as a separate communication path, allowing the system to divide the communication task across multiple frequencies to ensure reliability while managing complexity through modular channel management.
Solution Approach 2:
The system changes the frequency parameter by operating multiple communication channels at different radio carrier frequencies. This parameter diversification allows the system to bypass RF environment challenges affecting any single frequency, thereby improving communication reliability without requiring overly complex error correction mechanisms.
2Reliability
If multiple wireless communication channels operating at different frequencies are activated in parallel, then communication security improves by preventing man-in-the-middle attacks, but device complexity and energy consumption increase
Solution Approach 1:
Security is segmented across multiple parallel communication channels at different frequencies. By distributing security-critical communications across these channels and implementing authentication protocols on each, the system achieves enhanced security through diversity, making it difficult for a single point of failure or attack to compromise the entire communication system.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism using public key infrastructure and digital certificates. This intermediary security layer verifies the identity of communicating vehicles before establishing secure channels, preventing man-in-the-middle attacks while managing complexity through standardized cryptographic protocols rather than custom complex security implementations.
3Reliability
If GPS is used for vehicle location tracking, then measurement precision is sufficient in most areas, but reliability deteriorates in areas where GPS signals are weak or unreliable
Solution Approach 1:
The system merges GPS-based location tracking with route circuit-based location determination into a unified hybrid system. By combining these two location determination methods, the system achieves reliable location tracking across all areas - using GPS when available and route circuits as a reliable backup or primary method in areas with weak GPS signals, thereby improving overall reliability without sacrificing precision.

AI summary
A method is provided that can include activating at least two wireless communication channels in parallel, between a first wireless transceiver and a second wireless transceiver. Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.
