Flight Control Priority Setting for Aircraft Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flight control systems for unmanned aircraft bias the burden of collision avoidance to one vehicle, potentially impairing its safety.
Innovation Solution
A flight control device that sets a priority relationship between two aircraft based on acquired information to determine which aircraft should perform collision avoidance, ensuring both vehicles' safety is maintained.

Engineering Contradiction Analysis
1Device complexity
If a flight control system assigns collision avoidance burden to one aircraft, then the control logic is simplified, but the safety of that one aircraft is impaired
Solution Approach 1:
The collision avoidance responsibility is segmented between multiple aircraft based on priority relationships. Instead of one aircraft bearing the entire burden, the system divides the avoidance task by establishing which aircraft (subject or counterpart) should perform avoidance maneuvers based on acquired aircraft information, thereby distributing the safety burden while maintaining manageable control logic for each individual aircraft.
Solution Approach 2:
Rather than having one aircraft unilaterally perform collision avoidance, the system inverts the approach by enabling both aircraft to assess the situation and determine priority relationships. This allows the aircraft with higher priority (determined through information exchange) to be responsible for avoidance, preventing the safety impairment that occurs when the burden is unfairly concentrated on one vehicle.
2Reliability
If priority relationship setting is implemented between two aircraft, then both aircraft safety is maintained, but the device complexity increases
Solution Approach 1:
The flight control device is designed with multi-functionality to handle both normal flight control and collision avoidance priority determination. By integrating the priority relationship setting capability into the existing flight control system, the patent avoids adding separate complex subsystems, thereby maintaining both aircraft safety through priority-based avoidance while limiting the increase in overall device complexity.
Solution Approach 2:
Each aircraft independently acquires its own information and the counterpart aircraft information, then autonomously determines the priority relationship without requiring complex external arbitration. This self-service approach allows both aircraft to maintain safety through decentralized decision-making while avoiding the complexity of centralized control systems.

AI summary
A technique controls a subject aircraft which is a flight vehicle. In the technique, subject aircraft information is acquired as information on the subject aircraft, and counterpart aircraft information is acquired as information on a counterpart aircraft that is a flight vehicle different from the subject aircraft. A priority relationship is set according to the subject aircraft information and the counterpart aircraft information. The priority relationship indicates which of the subject aircraft and the counterpart aircraft has higher priority in performing collision avoidance flight that is flight for avoiding a collision between the subject aircraft and the counterpart aircraft.
