Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-road vehicles often experience unstable communication networks due to limited or no cellular service in outdoor areas, leading to frequent disconnections and poor vehicle networking stability.
Innovation Solution
A communication method for off-road vehicle groups utilizing portable communication devices equipped with short-range and long-range communication modules, allowing for unlicensed communication and positioning information sharing without reliance on cellular networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cellular service is used for vehicle communication, then data sharing and communication between vehicles can be realized, but communication stability deteriorates in areas with poor signal coverage
Solution Approach 1:
The patent introduces a portable communication device as an intermediary between off-road vehicles. This device includes short-range communication modules that enable direct vehicle-to-vehicle communication without relying on cellular infrastructure, and long-range communication modules that can bridge gaps when vehicles are out of direct range. The portable device acts as a mediator that maintains communication stability in areas where cellular service is unavailable.
Solution Approach 2:
The communication system is segmented into multiple communication ranges: short-range modules for direct vehicle-to-vehicle communication and long-range modules for extended communication. This segmentation allows the system to adapt to different spatial configurations and maintain reliability whether vehicles are close together or dispersed in areas with poor cellular coverage.
2Reliability
If short-range communication is used for vehicle communication, then communication stability is improved, but communication range is limited
Solution Approach 1:
The patent merges short-range communication modules and long-range communication modules into a single portable communication device. The short-range modules provide stable direct communication, while the long-range modules extend the communication horizon. By combining these different communication technologies in one device, the system achieves both stability and extended range without requiring separate systems.

AI summary
A communication method for an off-road vehicle group is applied to a first portable communication device. The first portable communication device includes a short-range communication module and a long-range communication module, both sending and receiving unlicensed transmissions, as well as a positioning module such as a GPS chip. The method includes: establishing a communication between the first portable communication device and a first off-road vehicle based on the short-range communication module, and obtaining driving information of the first off-road vehicle; establishing a communication between the first portable communication device and a second portable communication device based on the long-range communication module, and the second portable communication device establishing a communication with a second off-road vehicle; and sending driving information of the first off-road vehicle and location information of the first portable communication device to the second portable communication device based on the long-range communication module.
