Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the platoon is divided into old string and new string due to an event, then the safety and adaptability of autonomous driving are improved, but the complexity of platoon management and traffic flow continuity deteriorate
Solution Approach 1:
The platoon is divided into old string and new string when an event occurs, allowing independent management of different vehicle groups. This segmentation enables safer event handling while maintaining overall system control through the processor that monitors both strings separately
Solution Approach 2:
The processor determines recombination conditions in advance before actually recombining the strings. By pre-assessing conditions such as distance, traffic congestion level, and lane availability, the system prepares for safe recombination while maintaining current string separation, thus managing complexity proactively
2Productivity
If the divided strings are recombined after event, then the efficiency of platooning is improved, but the risk of traffic congestion and safety issues increases
Solution Approach 1:
The processor continuously monitors multiple conditions (distance between strings, traffic congestion level, number of free lanes, autonomous driving function status) to determine when recombination is safe. This feedback mechanism ensures recombination only occurs when conditions are favorable, reducing congestion and safety risks while maintaining platooning efficiency
Solution Approach 2:
The system evaluates multiple parameters simultaneously (distance, traffic congestion level, lane availability) to determine recombination timing. By changing the state from separated to recombined based on parameter thresholds, the system optimizes efficiency while minimizing harmful effects through data-driven decision-making
3Reliability
If multiple conditions are checked for recombination, then the safety and reliability are improved, but the complexity of control system increases
Solution Approach 1:
The processor performs multiple functions: monitoring string separation, evaluating recombination conditions, controlling recombination execution, and managing autonomous driving functions. By consolidating these diverse functions into a single processor, the system improves safety through comprehensive monitoring while avoiding the complexity of multiple separate control systems

AI summary
The present disclosure provides a platooning controller and a method thereof. The platooning controller includes a processor that, when a string is divided into an old string and a new string due to occurrence of an event during platooning, recombines the divided strings after the occurrence of the event is ended. The controller includes a storage storing data and an algorithm run by the processor. The processor determines a condition where it is possible to recombine the divided strings and controls recombination between the divided strings.
