Vehicle Control Device for Position-Based Message Subscriptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication methods for vehicles, such as periodic communication with servers, lead to increased processing load on servers and communication bandwidth when a large number of vehicles are involved, causing pressure on the communication band.
Innovation Solution
A control device for movable apparatuses that includes a position information acquisition unit, a distribution connection area acquisition unit, and a transmission unit to manage and optimize communication by determining distribution connection areas based on vehicle position, allowing for efficient subscription and cancellation of messages, thereby reducing unnecessary communication and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles communicate with servers periodically to transmit position information, then the server can provide information to vehicles, but the processing load on the server and communication bandwidth increase significantly when a large number of vehicles are involved
Solution Approach 1:
The server performs preliminary actions by proactively pushing distribution connection area information to vehicles before the vehicles need to request it. This allows vehicles to pre-register their subscription interests and receive information pushes when entering distribution areas, eliminating the need for continuous periodic communication and reducing overall bandwidth consumption while maintaining reliable information delivery
Solution Approach 2:
Vehicles autonomously determine whether to register or cancel subscriptions based on their own position information and the distribution connection area information they receive. This self-service mechanism reduces server processing load by eliminating the need for the server to manage subscription states for all vehicles, while still ensuring reliable information delivery through automated position-based triggers
2Extent of automation
If vehicles transmit position information periodically to the server, then the server can manage information distribution, but the vehicle processing load and communication frequency increase
Solution Approach 1:
The system replaces continuous periodic communication with event-driven periodic action. Vehicles only communicate with the server when specific events occur: when they receive distribution connection area information and need to register subscriptions, or when they exit distribution areas and need to cancel subscriptions. This event-driven approach maintains automated information distribution while dramatically improving communication efficiency by eliminating unnecessary periodic transmissions
Solution Approach 2:
The patent extracts the essential function of position monitoring from continuous communication and implements it through position information acquisition units in vehicles that locally determine when subscription actions are needed. This extraction allows the server to focus only on pushing distribution area information and handling subscription requests, improving overall system productivity while maintaining automated distribution
3Adaptability or versatility
If the server processes position information from all vehicles periodically, then information can be distributed, but the server processing load increases with the number of vehicles
Solution Approach 1:
Vehicles autonomously manage their own subscription states by comparing their position information with distribution connection area information. This self-service approach allows the system to scale to large numbers of vehicles without proportionally increasing server processing power, as each vehicle independently determines when to register or cancel subscriptions rather than requiring server-mediated position management for all vehicles
Solution Approach 2:
The server performs preliminary action by pushing distribution connection area information to vehicles in advance, allowing vehicles to proactively register subscriptions before needing information. This preliminary action reduces real-time server processing requirements, enabling the system to scale to more vehicles without linearly increasing server processing power demands
