Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle bus protocols are inadequate for non-safety communications due to low bandwidth and transmission speed, limiting information flow, data security, and remote access while maintaining security against unauthorized parties.
Innovation Solution
A vehicle middleware system with a microprocessor executable media controller that manages media streams, identifies restricted input/output systems, and applies rules to ensure compliance with operator commands and governing laws, enabling improved data stream management and integration across diverse systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If existing vehicle bus protocols are used for non-safety communications, then device compatibility is maintained, but bandwidth and transmission speed are insufficient
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the existing vehicle bus system and external communication networks. This gateway translates and mediates data transmission, enabling high-speed communication while maintaining compatibility with legacy vehicle protocols through protocol conversion and data formatting functions.
2Loss of information
If vehicle bus protocols are used for non-safety communications, then system simplicity is maintained, but information flow and data security are limited
Solution Approach 1:
The patent segments the communication system into distinct functional modules: a core vehicle bus system for safety-critical communications, a gateway layer for protocol translation and security management, and external communication interfaces for high-bandwidth data transfer. This segmentation allows information flow enhancement in non-safety channels without compromising the simplicity and reliability of the core vehicle system.
3Ease of operation
If remote access is enabled without restrictions, then ease of access is improved, but security against unauthorized parties deteriorates
Solution Approach 1:
The patent implements dynamic access control mechanisms that adaptively manage remote connectivity. The system continuously evaluates security contexts, authentication credentials, and operational states to dynamically adjust access permissions, enabling seamless authorized remote access while automatically blocking unauthorized attempts through real-time security policy enforcement.

AI summary
The present disclosure describes a microprocessor executable media controller operable to receive a media stream from a remote node, the received media stream being for an occupant associated with an on board vehicle input/output system, identify which on board vehicle input/output systems are restricted due to operator command and/or as a result of a governing law, and provide the media stream, in compliance with any restriction, to a selected input/output system associated with the occupant.
