Mine Vehicle V2V Coordination for Collision Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles on mine sites face challenges in collision avoidance due to the lack of consideration for other vehicles in trajectory planning, relying on centralized platforms that are prone to latency, outages, and blind spots.
Innovation Solution
Implementing Vehicle-to-Vehicle (V2V) communication to enhance obstacle detection and classification, allowing autonomous vehicles to exchange localization and mission information to improve collision prediction and path planning, even during network outages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized platforms are used for collision prevention, then autonomous vehicles can receive mission control and trajectory planning, but the system becomes prone to latency, outages and blind spots
Solution Approach 1:
The patent introduces V2V communication as an intermediary layer between autonomous vehicles and the centralized platform. This mediator enables direct peer-to-peer information exchange about vehicle positions, trajectories, and intentions, reducing dependency on the centralized network infrastructure and mitigating latency and outage issues while maintaining system coordination
2Loss of information
If sensor perception is used for obstacle detection, then autonomous vehicles can detect other vehicles, but the system lacks knowledge of vehicle positions for trajectory planning
Solution Approach 1:
The patent merges sensor-based perception data with V2V communication data to create a comprehensive view of the operating environment. By combining direct sensing with information exchanged between vehicles about their positions and trajectories, the system overcomes the limitations of either approach alone, achieving both complete position information and accurate detection
3Reliability
If V2V communication is implemented for obstacle detection, then collision avoidance capabilities are improved, but the system requires additional communication interfaces and data processing
Solution Approach 1:
The V2V communication interface is designed to serve multiple functions simultaneously: it enables direct vehicle-to-vehicle communication for collision avoidance, exchanges classification information for obstacle identification, and shares trajectory data for path planning. This multi-functionality reduces the need for separate dedicated systems for each function, mitigating the increase in overall system complexity
