Dual-Device Request Coordination for Priority Processing Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As vehicle functions become more diverse and complicated, coordinating a large number of processing execution requests in a single processing device becomes challenging due to increased processing load and speed requirements.
Innovation Solution
A control system with a first electronic device and a second electronic device that coordinate execution requests, where the first device determines processing order based on first priority ranks and the second device determines transmission order based on second priority ranks, allowing for efficient coordination and processing of multiple requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all processing requests are coordinated in one processing device, then centralized control is achieved, but processing load and coordination speed become problematic when the number of requests increases
Solution Approach 1:
The patent divides the coordination function into two separate electronic devices: a first electronic device that coordinates all execution requests from multiple devices, and a second electronic device that coordinates only the execution requests it receives and transmits to the first device. This segmentation allows each device to handle a smaller subset of requests, improving processing speed while maintaining centralized control through the first device's ultimate authority over all requests.
2Adaptability or versatility
If the types and frequency of processing execution requests increase, then system functionality improves, but coordination difficulty increases
Solution Approach 1:
By segmenting the coordination workload between two electronic devices, the system can handle increased types and frequencies of requests without overwhelming a single coordinator. The second device filters and pre-coordinates requests before they reach the first device, reducing the complexity burden on the central coordinator while allowing the system to accommodate more diverse and frequent requests.
Solution Approach 2:
The second electronic device acts as an intermediary between the multiple source devices and the first electronic device. It receives execution requests, performs preliminary coordination based on second priority ranks, and transmits selected requests to the first device. This intermediary role simplifies the overall coordination complexity by distributing the coordination burden and filtering requests before they reach the main coordinator.
3Manufacturing precision
If priority ranks are densely assigned without available ranks, then processing order is precise, but adaptability to new requests decreases
Solution Approach 1:
The system performs preliminary assignment of available priority ranks to execution requests at the second electronic device before transmitting them to the first device. By pre-assigning priority ranks and identifying available ranks in advance, the system maintains precise processing order while preserving adaptability to accommodate new requests without requiring updates to the first device's coordination table.

AI summary
A control system includes a first electronic device that processes execution requests from a plurality of devices in an order according to a first priority rank that is assigned to each execution request, and a second electronic device that receives execution requests from some of the plurality of devices and transmits the execution requests to the first electronic device in an order according to a second priority rank that is assigned to each execution request.
