Vehicle Middleware for Data Stream Management

The patent segments the communication system into multiple layers: existing vehicle bus protocols (CAN, LIN) are retained for safety-critical communications, while a new middleware layer is introduced to handle non-safety communications. This segmentation allows high-speed data transfer for entertainment and information services without compromising the simplicity and reliability of safety-critical systems.

The patent introduces a middleware component as an intermediary between the existing vehicle bus protocols and new high-speed communication requirements. This middleware manages data streams, handles protocol conversion, and coordinates between different communication layers, enabling enhanced transmission speed while maintaining compatibility with existing systems.

The patent implements dynamic data stream management where the middleware adapts communication parameters, priority levels, and security measures based on real-time vehicle state and communication requirements. This dynamic approach enhances data security and information flow management without requiring overly complex static control systems.

The middleware is designed with multi-functionality to handle various communication protocols, security mechanisms, and data stream management tasks within a single integrated component. This universal design provides comprehensive data security and information flow control without proportionally increasing system complexity.

The patent employs a nested architecture where the middleware layer is embedded within the existing vehicle bus structure. Multiple processing modules are organized in hierarchical layers, with the middleware nesting communication management functions within the broader vehicle network architecture. This nesting provides adaptability and versatility while maintaining a manageable system structure.

The patent adds a new dimensional layer to the vehicle communication architecture by introducing the middleware between the physical bus layer and the application layer. This dimensional change enables multiple processing modules to operate in different functional dimensions (safety-critical vs. non-safety communications) without creating excessive horizontal complexity.
