Find Innovative SolutionsGenerate Solutions
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 includes a server for storing calibration databases and receiving calibration signals from responders, and a requester that invokes calibration signals from the server to read or write calibration values, enabling remote online calibration across multiple vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If local calibration system is used for single vehicle, then calibration function is automatic, but it cannot monitor or operate multiple vehicles simultaneously
Solution Approach 1:
The patent introduces a server as an intermediary component that centralizes calibration data storage and management. Multiple responders (vehicle ECUs) and requesters (calibration tools) communicate through this server, enabling multi-vehicle calibration without requiring complex peer-to-peer connections between all components. The server acts as the mediator that facilitates data fusion and coordination across distributed vehicles.
Solution Approach 2:
The calibration system is segmented into distinct functional roles: responders (vehicle ECUs that provide calibration data), requesters (tools that invoke calibration operations), and a central server (that manages data storage and coordination). This segmentation allows each component to have specialized functions, improving overall system versatility while maintaining manageable complexity through clear role differentiation.
2Ease of operation
If manual program duplication is used for multiple locations, then each location can calibrate locally, but program maintenance and data fusion become difficult
Solution Approach 1:
The server implements a universal calibration database and coordination mechanism that serves all locations simultaneously. Instead of maintaining separate calibration programs at each location, the same calibration data and operations can be accessed universally by any requester through the server. This multi-functional approach allows a single calibration program to serve multiple vehicles and locations, eliminating the need for manual duplication and simplifying program management.
Solution Approach 2:
The system uses centralized calibration data storage on the server that can be copied or accessed by multiple requesters simultaneously. Rather than distributing and manually updating calibration programs at each location, the server maintains the master copy that all locations can access and use, ensuring consistency and eliminating program management complexity.
3Reliability
If separate programs are written for local and remote calibration, then local calibration works, but remote ECU access and data fusion cannot be achieved
Solution Approach 1:
The patent merges local and remote calibration operations into a unified system architecture. The server combines calibration data from multiple responders and coordinates operations between requesters and responders in a single integrated platform. This merging eliminates the need for separate programs and enables automatic data fusion, improving reliability by ensuring consistent data handling across all calibration operations.
Solution Approach 2:
The server implements feedback mechanisms that allow requesters to invoke calibration operations and receive results, while responders provide calibration data and status information back to the server. This feedback loop ensures that calibration data is accurately transmitted and processed, maintaining data reliability while the server handles the complexity of coordination automatically.
