Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-road vehicles face challenges in communicating their state to other vehicles when traveling on vast, rough terrains devoid of defined routes, especially when outside cellular coverage, making it difficult for drivers to alert others to specific states such as mechanical issues or needing assistance.
Innovation Solution
A calling system for off-road vehicles that includes processing circuitry to obtain location information and specific state signals, allowing wireless transmission of calling signals directly between vehicles using RF communication, enabling two-way voice and data exchange without relying on base station intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cellular communication is used for off-road vehicles, then communication coverage is provided, but it becomes unavailable in remote areas without cellular coverage
Solution Approach 1:
The patent introduces a peer-to-peer communication system where off-road vehicles act as intermediary nodes to relay messages. When one vehicle cannot directly communicate with another due to distance or terrain, intermediate vehicles forward the communication signals, enabling reliable communication across vast remote areas without traditional cellular infrastructure.
Solution Approach 2:
The communication system is designed to function universally across different environments by combining direct wireless communication for nearby vehicles with relay communication through intermediate vehicles for distant vehicles. This multi-functional approach ensures communication availability whether vehicles are within direct range or need to use relay nodes in remote areas.
2Adaptability or versatility
If direct wireless communication is used between off-road vehicles, then communication in remote areas is enabled, but communication range is limited to nearby vehicles
Solution Approach 1:
The communication range is segmented into direct communication zones for nearby vehicles and relay communication zones for distant vehicles. The system automatically determines whether to use direct communication or route messages through intermediate vehicles based on the relative positions and communication capabilities of the vehicles involved.
Solution Approach 2:
The system transitions from two-dimensional direct vehicle-to-vehicle communication to a three-dimensional communication architecture that includes intermediate relay vehicles. This adds a dimensional layer to communication routing, allowing messages to traverse greater distances by hopping through multiple vehicles in sequence.
3Loss of information
If off-road vehicles communicate state information, then situational awareness is improved, but response time increases when cellular coverage is absent
Solution Approach 1:
Vehicles continuously broadcast their state information (location, status, destination) in advance using wireless communicators. This preliminary communication ensures that when vehicles need assistance or need to alert others of their presence, the information is already available to nearby vehicles, reducing response time even in remote areas without cellular coverage.
Solution Approach 2:
The system implements feedback mechanisms where receiving vehicles acknowledge received state information and can respond with their own status or assistance offers. This continuous feedback loop ensures timely responses to emergency situations or coordination needs, maintaining rapid communication despite the absence of cellular infrastructure.

Data Source
AI summary
A calling system for off-road vehicles includes processing circuitry. The processing circuitry is configured to: obtain location information indicating a location of a first off-road vehicle; obtain a specific state signal indicating that the first off-road vehicle is in a given specific state; and cause a first wireless communicator of the first off-road vehicle to, based on the specific state signal, wirelessly transmit a calling signal containing the location information, wherein the wireless transmission of the calling signal by the first wireless communicator is performed using a wireless communication technology in which the calling signal transmitted from the first wireless communicator is received directly by a second wireless communicator of a second off-road vehicle.
