Problem

Existing fleet management systems for autonomous vehicles lack efficient demand anticipation and control mechanisms, particularly for autonomous flying vehicles, leading to suboptimal resource allocation and operational inefficiencies.

Innovation Solution

A computer-implemented method and system for controlling a fleet of autonomous vehicles, which involves obtaining missions from a master schedule, generating vehicle commands based on mission parameters, maintaining persistent connections with vehicles, sending commands for mission execution, and monitoring vehicle operations to adjust commands as needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If centralized fleet management systems are implemented to control large autonomous vehicle fleets, then resource allocation and operational control improve, but system complexity and cost increase

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidfleet management system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The fleet management system is segmented into multiple hierarchical levels: centralized cloud-based components for strategic decision-making and local onboard controllers for tactical execution. This segmentation allows the system to handle large fleets without overwhelming central infrastructure, improving scalability while maintaining control efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by pre-planning flight paths, pre-coordinating with air traffic control, and pre-positioning vehicles based on predictive analytics. This reduces real-time computational burden and enables faster response to dynamic conditions without increasing system complexity.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If real-time monitoring and control of autonomous vehicles is implemented, then operational safety and mission execution improve, but communication requirements and system resources increase

Engineering Contradiction:
Improvemission execution reliabilityVSAvoidcommunication energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic status reporting and command transmission instead of continuous communication. Vehicles report key parameters at scheduled intervals or upon significant events, reducing communication overhead and energy consumption while maintaining adequate monitoring for safe operation.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

Vehicles autonomously monitor their own status, detect anomalies, and execute corrective actions without constant controller intervention. This self-service capability reduces communication requirements while maintaining high reliability through onboard decision-making algorithms.

Inventive Principle:
Principle #25Self-service

3Productivity

If predictive analytics and demand anticipation systems are added to fleet control, then resource allocation optimization improves, but computational requirements and processing time increase

Engineering Contradiction:
Improveresource allocation optimizationVSAvoidcomputational processing time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs predictive analytics and demand forecasting in advance using historical data and machine learning models. By pre-computing resource allocation strategies and vehicle positioning recommendations, the system reduces real-time computational requirements while maintaining optimization benefits.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Complex real-time computational problems are replaced with pre-computed lookup tables and simplified decision rules derived from predictive analytics. This substitution reduces processing time during critical operations while retaining the benefits of sophisticated optimization.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
