Solution Overview

Problem

Existing vehicle platooning systems lack efficient methods to consider parameters such as occupancy, autonomy level, safety, and priority when forming or joining platoons, leading to challenges in reaction time and space availability for new vehicles.

Innovation Solution

The system coordinates vehicle platooning by considering parameters like occupancy, autonomy level, and travel preference through V2X assistance, allowing vehicles to join platoons based on these factors, using C-V2X communications and platoon control systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If vehicles join platoons without considering occupancy, autonomy level, safety, and priority parameters, then the platoon formation process is simple and fast, but the platoon efficiency and safety deteriorate

Engineering Contradiction:
Improveplatoon safetyVSAvoidplatoon coordination complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by introducing multiple evaluation parameters (occupancy, autonomy level, safety, priority) to characterize vehicle suitability for platooning. The system dynamically adjusts platoon formation decisions based on these parameters, transforming the platoon coordination process from a simple binary decision to a multi-dimensional evaluation system that improves safety while maintaining manageable complexity through structured parameter assessment.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the system considers multiple parameters (occupancy, autonomy level, safety, priority) for platoon formation, then platoon efficiency and safety improve, but the coordination complexity and processing time increase

Engineering Contradiction:
Improveplatoon formation efficiencyVSAvoidreaction time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-establishing evaluation criteria and parameter thresholds for platoon formation before actual platoon operations begin. The system prepares the multi-parameter evaluation framework in advance, so that when vehicles seek to join platoons, the coordination process can quickly reference pre-defined safety and efficiency standards rather than computing everything in real-time, thus reducing reaction time while maintaining comprehensive evaluation.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If vehicles are allowed to join platoons without parameter verification, then space availability and access are improved, but platoon coordination and safety are compromised

Engineering Contradiction:
Improvevehicle access to platoonVSAvoidplatoon safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies feedback by implementing a verification mechanism where vehicles seeking to join platoons receive evaluation results based on their occupancy, autonomy level, safety, and priority parameters. The system provides feedback to vehicles about their platoon eligibility status, allowing easy access for qualified vehicles while automatically filtering out unsuitable candidates, thus maintaining both ease of operation for legitimate vehicles and high safety standards through continuous parameter verification.

AI summary

Certain aspects of the present disclosure provide techniques for coordinating vehicle platooning with V2X assistance. The techniques generally include: a first vehicle associated with a source UE transmitting a request to a base station to join a vehicle platoon. The request indicates at least one of: an occupancy parameter of a first vehicle associated with the source UE; an autonomy level of the first vehicle; or a travel preference parameter. The occupancy parameter may include a number of passengers, seating positions of passengers, and other occupancy information pertaining safety and prioritization. The autonomy level enables vehicles of similar autonomy to form a platoon that optimizes headways, thus minimizing fuel consumption due to air resistance. The travel preference parameter may include a preferred speed of the source UE. The source UE may receive a response message indicating confirmation that the first vehicle is allowed to join the vehicle platoon.
