Cloud Diagnostic Server Cluster for Multi-Brand Vehicle Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diagnostic terminals have limited capabilities, making it difficult and costly for repair factories to diagnose multiple vehicle brands, requiring extensive resources and multiple accounts for different manufacturers.
Innovation Solution
A cloud diagnostic server cluster managed by a management server allocates corresponding diagnostic servers to terminals, allowing a single terminal to diagnose vehicles of different brands with improved efficiency and reduced costs, using a single user account.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a diagnostic terminal is configured with diagnostic functions for multiple vehicle brands, then the diagnostic capability is improved, but the device complexity and economic costs increase significantly
Solution Approach 1:
The patent implements a cloud-based diagnostic system where a single diagnostic terminal can access diagnostic services for multiple vehicle brands through a unified interface. The management server coordinates between the terminal and multiple brand-specific diagnostic servers, enabling one terminal to perform diverse diagnostic functions without requiring separate hardware or software configurations for each brand.
Solution Approach 2:
The management server acts as an intermediary between the diagnostic terminal and multiple brand-specific diagnostic servers. It receives diagnostic requests from the terminal, routes them to the appropriate diagnostic server based on vehicle brand, and returns results to the terminal. This mediator architecture allows the terminal to access multiple brands' diagnostic capabilities without directly integrating with each brand's system.
2Adaptability or versatility
If multiple diagnostic services are purchased for different vehicle brands, then the diagnostic coverage is improved, but the economic costs increase
Solution Approach 1:
The patent combines multiple brand-specific diagnostic services into a single unified diagnostic system. Instead of requiring separate diagnostic terminals or software licenses for each vehicle brand, the system merges access to all brand diagnostic servers through one terminal and one user account, reducing the need for multiple separate service purchases.
Solution Approach 2:
A single diagnostic terminal with unified client software provides universal access to diagnostic services for multiple vehicle brands. The system eliminates the need to purchase and maintain separate diagnostic solutions for each brand, achieving cost reduction while maintaining broad diagnostic coverage.
3Reliability
If multiple user accounts are required for different diagnostic services, then the access authorization is improved, but the ease of operation deteriorates
Solution Approach 1:
The system implements a unified user account system that provides universal access authorization across all diagnostic services. A single user account can authenticate and access diagnostic functions for multiple vehicle brands, eliminating the need to create, manage, and switch between multiple separate accounts while maintaining proper authorization control.
Solution Approach 2:
The management server acts as an intermediary that handles user authentication and authorization centrally. It verifies user credentials and grants appropriate access rights to different diagnostic servers based on the user's permissions, eliminating the need for users to manage multiple accounts while maintaining secure access control.
4Measurement precision
If extensive resources are allocated for analyzing diagnostic protocols of various vehicles, then the diagnostic accuracy is improved, but the productivity and time efficiency deteriorate
Solution Approach 1:
The management server serves as an intermediary that handles protocol analysis and data interpretation between the diagnostic terminal and various vehicle systems. It manages the complexity of different diagnostic protocols for various brands, allowing the terminal to maintain high diagnostic accuracy without requiring extensive local resources for protocol analysis.
Solution Approach 2:
The diagnostic servers for each vehicle brand autonomously handle their own protocol analysis and diagnostic processing. When the terminal sends a diagnostic request, the appropriate brand-specific server independently performs the protocol analysis and returns results, eliminating the need for the terminal to allocate extensive resources for analyzing diverse vehicle protocols.

AI summary
Embodiments of the present invention relate to the field of diagnostic technologies of a vehicle, and specifically disclose a diagnostic method for a vehicle. The method includes: receiving, by a diagnostic server, a connection request message sent by a terminal, the connection request message being used to request address information of a diagnostic server corresponding to a to-be-diagnosed vehicle; determining the corresponding diagnostic server according to the connection request message; and sending the address information of the diagnostic server to the terminal, so that the terminal establishes a communication connection with the diagnostic server according to the address information. According to the foregoing technical solutions, in the embodiments of the present invention, a plurality of vehicle can be diagnosed by using the terminal, improving diagnostic efficiency and achieving relatively high user experience.
