Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle platooning technologies face challenges in addressing benefit conflicts between vehicles, leading to instability and inefficiency in platoons, particularly when vehicles are owned by different individuals or service providers, which affects the stability and efficiency of traffic flow.
Innovation Solution
A vehicle platoon incentive mechanism based on a double auction, utilizing a bidding and price asking matrix to determine optimal platoon formations and redistribute benefits among participants, ensuring stability and efficiency through a trustworthy third-party controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If vehicle platooning is implemented to reduce aerodynamic drag and fuel consumption, then energy efficiency is improved, but benefit distribution among vehicles becomes unequal leading to instability
Solution Approach 1:
The patent introduces a benefit redistribution mechanism as an intermediary system that mediates between the aerodynamic drag reduction benefits and the stability requirements of the platoon. This mechanism calculates and redistributes benefits among vehicles based on their contributions, ensuring that all vehicles receive fair compensation for their participation, thereby maintaining platoon stability while achieving energy efficiency goals.
Solution Approach 2:
The patent changes the parameter of benefit distribution from equal allocation to proportional allocation based on each vehicle's contribution to drag reduction. By adjusting the benefit distribution parameters according to actual aerodynamic benefits received, the system ensures that vehicles contributing more to the platoon's efficiency receive greater benefits, thus maintaining stability while achieving overall energy savings.
2Use of energy by moving object
If vehicles are arranged in platoon formation to maximize drag reduction, then energy conservation is improved, but conflict among drivers or owners arises due to unequal benefits
Solution Approach 1:
The patent implements a feedback mechanism where the benefit redistribution system continuously monitors the aerodynamic benefits received by each vehicle and adjusts the distribution of incentives accordingly. This feedback loop ensures that drivers or owners see a direct correlation between their vehicle's contribution to drag reduction and the benefits they receive, thereby maintaining their willingness to participate in the platoon formation.
Solution Approach 2:
The patent applies local quality by providing differentiated benefit distribution to different vehicles based on their specific positions and contributions to the platoon. Instead of uniform treatment, each vehicle receives benefits proportional to its local contribution to drag reduction, ensuring that vehicles in different positions (leading, intermediate, trailing) are fairly compensated for their specific roles, thus maintaining driver willingness to participate.
3Adaptability or versatility
If vehicles leave the platoon to travel alone or join other platoons due to benefit conflicts, then individual vehicle autonomy is maintained, but traffic flow efficiency deteriorates
Solution Approach 1:
The patent introduces dynamic benefit redistribution that adapts to changing platoon compositions and vehicle positions. As vehicles join or leave the platoon, the system dynamically recalculates and redistributes benefits to maintain fairness and stability. This dynamic adjustment ensures that vehicles can maintain autonomy to join or leave platoons while the system continuously optimizes benefit distribution to prevent instability, thereby maintaining traffic flow efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism resolves benefit conflicts by promoting stable and efficient platoon formation, ensuring fair benefit distribution and behavioral stability, enhancing traffic flow efficiency and reducing energy consumption.
Implementation Method 1
when the vehicles travel closely enough to each other, a front vehicle reduces aerodynamic drag on a front surface of a rear vehicle, and generates higher pressure to provide propulsion for a leading vehicle

AI summary
A vehicle platoon incentive mechanism and system based on a double auction, a device, and a medium are provided. A highway system is conceived, where vehicles can be platooned and transmits their information to a controller. The controller searches for an optimal vehicle platoon to maximize a benefit of the vehicle platoon and redistribute the benefit among members in the vehicle platoon through a incentive mechanism to motivate a driver or a vehicle owner to form and maintain the optimal vehicle platoon. The incentive mechanism resolves a benefit conflict between vehicles through the benefit redistribution, thereby promoting formation of a stable and efficient vehicle platoon. The vehicle platoon incentive mechanism will make up for insufficient research on the vehicle platoon incentive mechanism. This mechanism can determine leader-follower positions and associated benefits, offering a potential solution to the instability in platooning behavior.
