Platooning Management Device for Fair Cost Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing platooning methods disproportionately increase the driving costs for leading vehicles, necessitating a system to equitably distribute these costs among vehicles in a platooning line while maintaining fuel efficiency and safety.
Innovation Solution
A platooning management device that calculates driving costs based on contribution, emergency level, fuel efficiency, and risk, and adjusts the platooning location by requesting vehicles with lower costs to take the lead, ensuring fair cost distribution and minimizing fuel consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If vehicles maintain platooning formation with a leading vehicle, then fuel efficiency of following vehicles is improved, but driving costs of the leading vehicle increase
Solution Approach 1:
The system dynamically adjusts the leading vehicle position based on real-time calculation of driving costs for each vehicle. Vehicles rotate the leading position according to their calculated cost burden, transforming a static role assignment into a dynamic, adaptive system that optimizes cost distribution while maintaining fuel efficiency benefits
Solution Approach 2:
The system changes the parameter of leading vehicle position based on calculated driving costs. By evaluating multiple parameters (fuel consumption, distance, time) and adjusting which vehicle assumes the leading role, the system achieves equitable cost distribution while preserving the aerodynamic benefits for all vehicles
2Device complexity
If the leading vehicle position is fixed, then platooning structure is simplified, but cost distribution among vehicles becomes unfair
Solution Approach 1:
The system implements dynamic role assignment where the leading vehicle position is not fixed but rotates based on real-time cost calculations. This dynamic approach maintains operational simplicity while achieving fair cost distribution through automated evaluation and position swapping protocols
3Ease of operation
If vehicles frequently swap leading positions, then cost distribution becomes more equitable, but platooning stability decreases
Solution Approach 1:
The system employs feedback mechanisms where driving costs are continuously calculated and evaluated. Position swaps are triggered only when cost differentials exceed predetermined thresholds, and stability protocols prevent excessive swapping by requiring confirmation cycles and maintaining minimum interval periods between position changes
Solution Approach 2:
The system prepares for potential position swaps by pre-calculating driving costs and establishing threshold criteria beforehand. Stability cushioning mechanisms are in place to prevent premature or excessive swapping, ensuring that position changes occur only when genuinely necessary for cost equity

AI summary
A platooning management device, a vehicle system including the same, and a method thereof are provided. The platooning management device includes a processor that calculates driving costs of vehicles in a platooning line, and compares the driving costs of the vehicles to determine whether it is necessary to change a location of a leading vehicle in the platooning line. When it is necessary to change the location, the processor performs location change control. A storage stores driving costs obtained by the processor and information received from the vehicles in the platooning line.
