Air-Ground UAV Pairing for Early Roadblock Rerouting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional unmanned ground vehicles face challenges in quickly responding to and avoiding roadblocks due to their limited ability to receive advanced obstacle detection information in real-time.
Innovation Solution
A near-field sensing information transmission and pairing system for air-land unmanned vehicles, where an unmanned aviation vehicle continuously senses obstacles on the ground and transmits re-routing signals to an unmanned ground vehicle, which calculates and transmits an alternative route based on map information and current coordinates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional unmanned ground vehicles use only onboard sensors for obstacle detection, then the vehicle structure remains simple, but the reaction time to avoid roadblocks is insufficient
Solution Approach 1:
An unmanned aviation vehicle serves as an intermediary aerial sensor platform that detects obstacles ahead of the ground vehicle and transmits early warning information, enabling the ground vehicle to react earlier to roadblocks while keeping the ground vehicle's own sensor system relatively simple
Solution Approach 2:
The detection system transitions from a two-dimensional ground-based sensor array to a three-dimensional air-ground collaborative system, where the aerial vehicle provides top-down and forward viewing capabilities that extend the detection horizon beyond what ground-mounted sensors can achieve
2Reliability
If unmanned ground vehicles wait for vehicles behind to reverse when blocked, then collision avoidance is achieved, but the immediacy of avoiding roadblocks is poor
Solution Approach 1:
The aerial unmanned vehicle performs preliminary detection of obstacles and traffic control features before the ground vehicle reaches them, transmitting early warning information that enables the ground vehicle to take preventive action such as changing lanes or stopping before the obstacle, rather than reacting after being blocked
3Ease of operation
If remote operators take over self-driving vehicles in emergency situations, then troubleshooting capability is improved, but the ability to obtain advance obstacle information for re-routing remains insufficient
Solution Approach 1:
The system performs preliminary detection and transmission of obstacle information before the ground vehicle encounters the emergency situation, providing advance warning that enables automated or operator-assisted re-routing decisions rather than waiting for remote operators to respond after the vehicle is already blocked

AI summary
A near-field sensing information transmission and pairing system for air-land unmanned vehicles and a method thereof are disclosed. The unmanned aviation vehicle is driven to move along a forward route of an unmanned ground vehicle in advance, and continuously senses whether an obstacle or a traffic control appears in the forward route; when sensing the presence of the obstacle or the traffic control feature, the unmanned aviation vehicle generates and transmits a re-routing signal to the unmanned ground vehicle, an alternative route is calculated to replace the original forward route based on map information, a current coordinate, an obstacle coordinate and a destination coordinate, so as to increase a reaction time of the unmanned ground vehicle, thereby achieving the technical effect of improving immediacy of the unmanned ground vehicle to avoid a roadblock.
