Vehicle Communication Control Device Message Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle communication systems, the concentration of message processing on specific hardware resources can lead to network overload and message omission or delay, as each resource has limited processing capacity.
Innovation Solution
A vehicle communication control device and method that allocates messages to multiple hardware resources based on preset criteria, such as communication period information and identification number information, to distribute the load and prevent message omission, using a storage device and controller to manage message allocation and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If messages are concentrated and allocated to a specific hardware resource, then the processing capacity of that resource is utilized efficiently, but the vehicle communication network experiences load and message omission or delay
Solution Approach 1:
The patent segments message allocation by dividing messages into different groups based on communication periods (first group with first communication period, second group with second communication period) and allocating them to different hardware resources. This segmentation prevents concentration of all messages on a single resource, thereby maintaining reliability while utilizing processing capacity.
Solution Approach 2:
The patent applies local quality by assigning different allocation strategies to different message groups based on their specific communication period characteristics. Messages with different communication periods are allocated to different hardware resources according to their specific needs, optimizing processing for each group while preventing overall system overload.
2Productivity
If a new message is requested for a hardware resource that has already reached the processing limit state, then the hardware resource is fully utilized, but the processing of the new message is omitted or delayed
Solution Approach 1:
By segmenting messages into different groups based on communication periods and allocating them to different hardware resources, the patent ensures that when one hardware resource reaches its processing limit, other resources are still available to handle additional messages from different groups, preventing message omission and delay.
Solution Approach 2:
The patent implements dynamic message allocation where the allocation of messages to hardware resources is adjusted based on communication period characteristics and current resource states. This dynamic approach allows the system to adaptively distribute messages to available resources, preventing overload and ensuring timely processing.
3Reliability
If messages are allocated based on communication period information and identification number information, then message distribution across hardware resources is improved, but the complexity of message allocation management increases
Solution Approach 1:
The patent uses parameter changes by allocating messages based on specific message parameters such as communication period information and identification number information. This parameter-based allocation approach achieves balanced distribution across hardware resources while maintaining manageable complexity through systematic rules.
