Vehicle Convoy Communication System for Multi-Channel Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intelligent transport systems (ITS) are limited in their ability to enable effective communication between multiple vehicles in convoy situations, primarily focusing on road management and safety, and do not adequately support data exchange necessary for maintaining vehicle coordination in convoy scenarios.
Innovation Solution
A method and system for managing a vehicle convoy through the exchange of setup and confirmation messages, including convoy data messages that contain essential vehicle configuration settings and status information, utilizing various communication channels such as LTE-V, DSRC, and mobile telecommunications networks to ensure effective data transfer between vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple communication channels are used for convoy data exchange, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The communication system is segmented into multiple independent channels (DSRC for direct vehicle-to-vehicle communication, LTE-V for networked communication, and mobile telecommunications as fallback). Each channel operates independently with its own protocol stack, allowing the system to select appropriate channels based on availability and requirements without requiring all channels to be simultaneously configured in a single complex system.
Solution Approach 2:
The convoy management system is designed with multi-functional communication capabilities that can operate across different channel types. The same convoy data messages and control logic can be transmitted via DSRC, LTE-V, or mobile networks, making the system universally compatible with multiple communication infrastructures without requiring separate systems for each channel.
2Reliability
If comprehensive convoy data messages are exchanged between vehicles, then coordination and safety are improved, but data transmission requirements and processing load increase
Solution Approach 1:
The system extracts and transmits only the essential convoy-relevant data elements through standardized message formats. Critical information such as vehicle position, speed, terrain settings, and navigation data are selectively extracted from the complete vehicle data set and transmitted in compact standardized formats, reducing overall data transmission requirements while maintaining coordination and safety.
Solution Approach 2:
The communication system adapts message parameters based on convoy conditions. Data transmission frequency, message size, and detail level are dynamically adjusted according to convoy speed, terrain complexity, and communication channel characteristics. This allows comprehensive coordination data to be transmitted efficiently by changing transmission parameters rather than always sending maximum detail.

AI summary
A method of managing a vehicle convoy, the method comprising: sending a convoy setup invitation message from a first vehicle to set up a vehicle convoy; receiving, at the first vehicle, a confirmation message from a second vehicle accepting the convoy setup invitation; sending, from the first vehicle, convoy data messages to the second vehicle, the convoy data messages comprising data required to maintain the vehicle convoy.
