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 remote control module that allows remote configuration and alteration of vehicle components, enabling improved data management, interoperability, and secure access through a dynamic software environment with Ethernet-based sensor technology and IPv6 connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If existing vehicle bus protocols are used, then device compatibility is maintained, but bandwidth and transmission speed are insufficient for non-safety communications
Solution Approach 1:
The patent introduces a gateway device as an intermediary between different bus protocols (CAN, LIN, FlexRay) and Ethernet-based networks. This gateway translates and mediates communications, allowing high-speed Ethernet traffic to flow through the legacy bus architecture without requiring changes to existing protocol-compatible components, thus resolving the contradiction between speed improvement and protocol adaptability.
Solution Approach 2:
The vehicle network is segmented into different domains: safety-critical domains continue to use traditional CAN/LIN protocols, while non-safety domains (infotainment, telematics, diagnostics) are connected via Ethernet through the gateway. This segmentation allows high-speed communications in non-safety domains without compromising the stability and compatibility of safety-critical systems.
2Ease of operation
If remote access is enabled, then user convenience is improved, but security against unauthorized access must be maintained
Solution Approach 1:
The gateway device serves as a security intermediary that all remote access requests must pass through. It implements authentication mechanisms, authorization policies, and encryption/decryption functions. This allows remote access convenience while maintaining security, as the gateway filters and controls all communications between external devices and vehicle systems.
Solution Approach 2:
The system implements self-service security features including automatic authentication, dynamic permission assignment, and real-time monitoring. The gateway autonomously manages security policies, authenticates devices, and controls access permissions without requiring manual intervention, thus maintaining security while enabling convenient remote access.
3Loss of information
If data management is enhanced, then information flow is improved, but data security requirements become more complex
Solution Approach 1:
The gateway acts as a centralized data management intermediary that implements security policies, encryption, and access control for all data transmissions. It manages information flow between different vehicle systems and external networks, enhancing information flow while consolidating security complexity into a single manageable component rather than distributing it across multiple systems.

AI summary
The present disclosure describes a microprocessor executable remote control module operable to receive, via a remote node, a command from a vehicle owner to configure and/or alter and/or determine a state of a selected vehicle component and, when the vehicle owner is authenticated successfully by the remote control module, to configure and/or alter and/or determine a state of the selected vehicle component.
