Autonomous Vehicle Platoon Scheduling After Overtaking Order Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous vehicle traffic systems face instability due to frequent overtaking and passing when the actual order of vehicles is switched, leading to impediments in stable traveling, as they do not account for changes in vehicle order.
Innovation Solution
An operation management apparatus and method that generates and modifies travel plans for autonomous vehicles to maintain the switched order after overtaking and passing, using a plan generator, communication device, and operation monitor to detect and adjust travel plans, and includes removing a vehicle if it is overtaken excessively to maintain system stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operation plan is maintained after vehicle order switching, then the original operation schedule is preserved, but frequent overtaking and passing occur causing unstable vehicle travel
Solution Approach 1:
The system dynamically adjusts the operation plan based on actual vehicle order changes. When overtaking and passing occur, the operation monitor detects the order switching and the plan generator modifies subsequent travel plans to accommodate the new vehicle sequence, making the system adaptive rather than rigid
Solution Approach 2:
The operation monitor continuously receives travel information from vehicles and detects order switching events. This feedback loop enables the system to identify when vehicle order changes occur and trigger appropriate plan modifications to maintain stable operation
2Reliability
If the operation plan is changed after vehicle order switching, then stable traveling is improved, but the complexity of plan management increases
Solution Approach 1:
The system extracts and isolates the order switching detection function into a dedicated operation monitor module. This separation allows the plan generator to focus on modifying travel plans based on clear signals from the monitor, simplifying the overall management complexity
Solution Approach 2:
The operation management system is divided into distinct functional modules: the operation monitor for detecting order changes and the plan generator for modifying travel plans. This segmentation allows each module to perform its specific function efficiently without overwhelming complexity
3Productivity
If a delayed vehicle overtakes and passes other vehicles to return to original order, then the operation plan is satisfied, but frequent overtaking impedes stable traveling
Solution Approach 1:
Instead of requiring the delayed vehicle to overtake and pass others to restore the original order, the system inverts the approach by modifying the operation plan to accept the new vehicle order. This eliminates the need for frequent overtaking maneuvers while still satisfying operational requirements

AI summary
An operation management apparatus includes a plan generator configured to generate a travel plan for each of a plurality of vehicles that form a line of vehicles and that travel autonomously along a predetermined travel route; a communication device configured to transmit the travel plans to the respective vehicles and receive, from the vehicles, travel information that indicates travel status of the vehicles; and an operation monitor configured to detect, based on the travel information, whether or not overtaking and passing of the vehicles have occurred. In response to the overtaking and passing, the plan generator modifies the travel plans so as to keep the order as switched upon the overtaking and passing.
