HD Platooning Maneuvers Based on Predicted V2V QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-density platooning driving maneuvers in transportation vehicles face challenges due to varying quality of service (QoS) in vehicle-to-vehicle communication, particularly in heterogeneous cellular network access and the presence of scattering and shadowing objects, which can affect the safety and efficiency of the convoy by altering inter-vehicle distances and energy consumption.
Innovation Solution
A method for determining high-density platooning driving maneuvers that considers a predicted quality of service (QoS) profile, selecting maneuvers based on energy consumption and packet inter-reception time criteria, and adjusting these maneuvers dynamically to ensure safe and efficient operation by using a processing device equipped with a microcontroller or microprocessor to perform the method, which includes testing strategies for closing and opening maneuvers and compensating for uncertainty in QoS predictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If high-density platooning maneuvers are performed with small inter-vehicle distances, then energy consumption is reduced, but communication reliability deteriorates due to varying QoS and scattering objects
Solution Approach 1:
The system dynamically adjusts the platoon formation and inter-vehicle distances based on real-time QoS conditions and predicted scattering object locations. The platooning maneuver is not static but adapts its parameters (distances, speeds, formations) according to environmental conditions and communication quality, resolving the contradiction between maintaining small distances for energy efficiency and ensuring communication reliability.
Solution Approach 2:
The system performs preliminary actions by predicting the locations of scattering and shadowing objects before they affect communication. Using environmental data and predictive algorithms, the system anticipates QoS degradation and proactively adjusts platoon formation or communication parameters in advance, preventing reliability issues before they occur while maintaining energy-efficient operation.
2Use of energy by moving object
If inter-vehicle distances are reduced for high-density platooning, then fuel efficiency improves, but safety risks increase due to communication uncertainties
Solution Approach 1:
The system implements continuous feedback loops that monitor actual communication quality, packet inter-reception times, and platoon performance. This feedback is used to adjust inter-vehicle distances and formation parameters in real-time, ensuring that safety margins are maintained even when operating in high-density configurations for fuel efficiency. The feedback mechanism allows the system to respond to unexpected QoS variations and maintain safe operation.
Solution Approach 2:
The system changes operational parameters such as inter-vehicle distances, relative speeds, and formation configurations based on predicted QoS profiles and scattering object locations. By dynamically adjusting these parameters, the system can operate in energy-efficient high-density modes when conditions permit while automatically increasing safety margins when communication reliability is compromised by environmental factors.
3Use of energy by moving object
If platooning maneuvers are optimized for energy efficiency, then fuel consumption decreases, but maneuver flexibility is reduced due to strict distance constraints
Solution Approach 1:
The system employs dynamic maneuver planning that adapts platoon formation and motion parameters based on real-time QoS conditions and predicted scattering object locations. Rather than following rigid distance constraints, the system continuously adjusts formation geometry, relative velocities, and maneuver timing to optimize energy efficiency while maintaining operational flexibility and adapting to changing environmental conditions.

AI summary
A method for determining a high-density platooning (HDPL) driving maneuver which includes selecting an HDPL closing maneuver, and selecting an HDPL opening maneuver. Closing maneuver means a maneuver with which the inter-vehicle distance between platoon members is decreased. Opening maneuver means a maneuver with which the inter-vehicle distance between platoon members is increased. The method also includes testing the selected HDPL maneuvers in terms of energy consumption taking into account a predicted quality of service (QoS) of a vehicle-to-vehicle V2V communication link for the communication between the platoon members. In response to the selected HDPL driving maneuvers not fulfilling the test criteria, the method waits a time and then selects an HDPL closing maneuver and an HDPL opening maneuver and tests the newly chosen HDPL maneuver again.
