Vehicle Convoy Sensor Data Sharing via Centralized Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle platoons, the coordination of sensor data sharing among vehicles is lacking, leading to excessive dispersion and affecting the safety of platoon driving.
Innovation Solution
A data sharing method and apparatus that utilizes a remote control end, such as a cloud server, to generate data sharing configuration information based on vehicle status information, determining sensor data sharing strategies for vehicles within the platoon, and distributing these strategies to facilitate coordinated sensor data sharing among vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vehicles in a platoon share sensor data without centralized coordination, then each vehicle can access sensor information from other vehicles, but the data sharing becomes excessive and dispersed, affecting platoon driving safety
Solution Approach 1:
A centralized coordination server is introduced as an intermediary between vehicles in the platoon. The server receives sensor data from each vehicle, processes and filters it according to platoon driving requirements, then distributes appropriate data to relevant vehicles. This mediator prevents excessive and dispersed data sharing by controlling what data is shared and with whom, thereby maintaining platoon driving safety while ensuring necessary information availability.
2Reliability
If a centralized system coordinates sensor data sharing in vehicle platoons, then data sharing becomes more organized and safe, but the system complexity increases
Solution Approach 1:
The centralized coordination server performs multiple functions within a single system: it collects sensor data from all vehicles, processes and filters the data, determines sharing strategies, and distributes data to appropriate vehicles. By consolidating these functions into one multi-functional system rather than having separate systems for each function, the overall system complexity is reduced while maintaining organized and safe data sharing.
3Loss of information
If sensor data is shared freely among all vehicles in a platoon, then information availability is high, but data dispersion becomes excessive and coordination is lost
Solution Approach 1:
Instead of uniform data sharing across all vehicles, the system applies local quality by tailoring data sharing to specific vehicles' needs. The centralized server analyzes which vehicles require which sensor data based on their positions, functions, and operational requirements within the platoon. Each vehicle receives a customized set of sensor data appropriate to its specific role, ensuring necessary information accessibility while preventing excessive dispersion and maintaining coordination stability.

AI summary
A data sharing method and apparatus applied to a vehicle convoy, and a medium and an electronic device. A vehicle convoy includes a plurality of vehicles. The data sharing method comprises: acquiring state information of each vehicle in a vehicle convoy, wherein the state information comprises sensor parameter information on the vehicle (S410); according to the state information of each vehicle, generating data sharing configuration information for the vehicle convoy, wherein the data sharing configuration information is used for representing a sensor data sharing policy of each vehicle (S420); and transmitting the data sharing configuration information to each vehicle in the vehicle convoy, such that each vehicle performs sensor data sharing processing according to the data sharing configuration information (S430).
