Solution Overview
Problem
Existing vehicular calibration systems are limited to local monitoring and cannot achieve simultaneous monitoring and interoperation across multiple vehicles distributed in different locations, requiring manual program duplication and lacking data fusion capabilities.
Innovation Solution
A vehicular multi-location synergic remote calibration method and system that utilizes a server, requester, and responder to store and manage calibration signals, allowing for remote calibration and data fusion across multiple vehicles by creating mapping system variables and using asynchronous functions for data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a local calibration system is used for single vehicle calibration, then the calibration process can be completed on one computer, but it cannot achieve simultaneous monitoring and data fusion across multiple vehicles in different locations
Solution Approach 1:
The patent introduces a server as an intermediary component that centralizes calibration data storage and management. The server receives calibration data from multiple responders across different locations and makes it accessible to requesters, enabling multi-location calibration without requiring complex peer-to-peer connections between all systems.
Solution Approach 2:
The calibration system is segmented into distinct functional components: requesters (initiating calibration), responders (providing calibration data), and a central server (managing data fusion). This segmentation allows each component to perform its specific function independently while contributing to the overall multi-location calibration capability.
2Loss of information
If separate programs are written for each location to access remote ECUs, then local calibration can be performed, but data fusion between different locations cannot be achieved
Solution Approach 1:
The server provides a universal platform that handles multiple functions: storing calibration data from any responder, retrieving data for any requester, and managing calibration signals across all locations. This eliminates the need to develop separate programs for each location, as the same server-based system serves all calibration needs.
Solution Approach 2:
The system establishes feedback loops where calibration data flows from responders to the server, and calibrated information flows back from the server to requesters and ultimately to ECUs. This structured feedback mechanism ensures that calibration information is continuously updated and fused across all locations without requiring separate program development.
3Productivity
If manual program duplication is used for multi-vehicle calibration, then each location can calibrate its vehicles, but simultaneous monitoring and interoperation across locations cannot be achieved
Solution Approach 1:
Instead of copying entire calibration programs to multiple locations, the system copies only the necessary calibration data through the centralized server. The server stores calibration signals and makes them available to all requesters, eliminating the time-consuming process of duplicating programs while enabling simultaneous access to calibration information across all locations.

AI summary
A vehicular multi-location synergic remote calibration method and system is provided. The vehicular multi-location synergic remote calibration method includes: a server, a requester and a responder; where the server stores a calibration database and receives and stores a calibration signal from the responder; the requester invokes the calibration signal from the server to read a calibration signal value; and/or, after the calibration signal is written, the requester sends a written target value to the responder through the server, and the responder completes vehicular online calibration and the requester reads a written calibration signal by applying to the server.
