Platooning Vehicle Data Charge Sharing via Master Access Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current platooning technologies in connected cars rely on individual data communication modules, leading to inefficient data charge management among vehicles, where vehicles with low communication charge rates or insufficient data capacity cannot utilize the data charge rates of others, limiting communication efficiency during platooning.
Innovation Solution
Implementing a method where vehicles share data charge rate information through V2V communication to determine a master vehicle that activates an access point for short-distance communication, allowing slave vehicles to access and use the master's data communication resources, thereby optimizing communication charge efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If each vehicle uses its own data communication module for V2V communication, then communication independence is maintained, but communication charge efficiency deteriorates when vehicles have low charge rates or insufficient data capacity
Solution Approach 1:
The patent merges the data communication resources of multiple vehicles by establishing a master-slave architecture where one vehicle (master) provides data communication services to other vehicles (slaves) in the platoon. This combining approach allows vehicles with sufficient data capacity to share their resources, improving overall communication charge efficiency while reducing the burden on individual vehicles.
Solution Approach 2:
The master vehicle performs multiple functions: it maintains its own data communication while simultaneously providing data communication services to slave vehicles through its data communication module. This multi-functionality enables a single vehicle to serve multiple purposes, improving resource utilization efficiency.
2Reliability
If vehicles maintain separate data communication modules, then communication reliability is preserved, but data charge rate optimization is limited
Solution Approach 1:
The system implements feedback mechanisms where slave vehicles report their data capacity status to the master vehicle, and the master vehicle adjusts its data communication allocation accordingly. This feedback loop enables dynamic optimization of data charge rates while maintaining communication reliability through continuous monitoring and adjustment.
Solution Approach 2:
The master-slave relationship is dynamic rather than static. Vehicles can switch roles based on real-time data capacity conditions, and the system adapts data communication parameters dynamically to optimize charge rates while maintaining reliable communication throughout the platoon.

AI summary
A vehicle and method of platooning control therefor are provided to achieve optimum communication charge efficiency while a plurality of vehicles perform platooning. A data communication method of a platooning vehicle includes starting platooning by a plurality of vehicles and sharing data charge rate information through a first protocol for vehicle-to-vehicle communication (V2V) by the plurality of vehicles. A first master vehicle and at least one slave vehicle are determined based on the shared data charge rate information. An access point (AP) is then activated according to a second protocol for short distance communication by the first master vehicle and an AP of the master vehicle is accessed and data communication is performed by the at least one slave vehicle.
