Ethernet TSN Reconfiguration Validation for Vehicle Data Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the ability to efficiently configure and validate real-time Ethernet data networks in motor vehicles, particularly for automated driving, due to limitations in vehicle electrical systems and control units, which restrict the addition of new driving functions and fail to ensure error-free reconfiguration without interfering with existing data streams.
Innovation Solution
An apparatus comprising a vehicle diagnostic device, data storage devices, and data checking devices that perform integrity checks to validate configuration changes, allowing for reconfiguration of Ethernet TSN networks, enabling updates and new driving functions while ensuring feasibility and minimizing network interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If configuration change data is transferred directly to the network without validation, then reconfiguration speed is improved, but network reliability deteriorates due to potential errors and interference with existing data streams
Solution Approach 1:
The patent applies preliminary action by performing integrity checks on configuration change data before it is transferred to the real-time Ethernet data network. The checking device validates the data using check values (such as CRC or hash values) to ensure correctness before activation, preventing erroneous configurations from reaching the network and thus maintaining reliability while enabling efficient reconfiguration.
2Manufacturing precision
If multiple parameters are configured manually in the network, then configuration precision is improved, but device complexity deteriorates due to the multiplicity of parameters and state machines
Solution Approach 1:
The patent applies copying by using pre-defined configuration templates or master configuration data that contain the correct settings for multiple parameters. Instead of manually configuring each parameter individually, the system copies validated configuration data to ensure precision while reducing the complexity of manual configuration processes. The checking device validates these copied configurations to maintain accuracy.
Solution Approach 2:
The patent applies universality by creating a multi-functional configuration system where a single configuration change data package can update multiple parameters across different network components simultaneously. The checking device performs universal validation on all parameters within the configuration package, ensuring precision while managing complexity through centralized configuration management rather than individual parameter handling.
3Adaptability or versatility
If memory resources are reserved for unknown functions, then adaptability is improved, but loss of substance deteriorates due to unavailable memory for current operations
Solution Approach 1:
The patent applies preliminary action by performing integrity checks and validation on configuration change data before it is activated in the network. This ensures that memory resources are only allocated after validation succeeds, preventing waste of memory resources on invalid or erroneous configurations while still allowing adaptability for future functions through validated configuration updates.
