Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern automotive vehicles face challenges in inter-communication operability between various Internet of Things (IoT) devices due to the use of different communication protocols, which hinders seamless data transmission and authentication within vehicle communication networks.
Innovation Solution
A vehicle communication system that employs an accessor module to encode data in an automotive connectivity communication protocol, including an object data portion defining a domain and a payload data portion, with a corresponding authentication protocol, allowing for authentication and encoding of the payload data according to an object-specific communication protocol, ensuring secure and protocol-agnostic data transmission between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different communication protocols are used for IoT devices in automotive vehicles, then device diversity and functionality are improved, but inter-communication operability and data transmission reliability deteriorate
Solution Approach 1:
The patent introduces an intermediary translation layer that converts data from multiple object-specific communication protocols into a unified automotive connectivity communication protocol. This mediator component receives data packets from diverse IoT devices using different protocols, translates them into a standardized format, and transmits them through the vehicle network, thereby enabling reliable communication between devices with different protocols without requiring each device to support all protocols directly
Solution Approach 2:
The patent implements a universal automotive connectivity communication protocol that serves as a common language for all IoT devices in the vehicle network. This universal protocol layer enables any device regardless of its native protocol to communicate with any other device, providing multi-functional compatibility across the entire network while maintaining the ability to handle device-specific protocols through translation
2Reliability
If protocol translation and authentication are performed for each data transmission, then security and interoperability are improved, but processing time and system complexity increase
Solution Approach 1:
The patent implements preliminary authentication and protocol translation setup during device initialization and network joining phases. Authentication credentials and protocol mapping configurations are pre-established before actual data transmission begins, allowing the system to perform rapid lookups and translations during operation without repeating complex authentication procedures for every data packet, thereby reducing real-time processing complexity while maintaining security
Solution Approach 2:
The patent divides the communication system into distinct functional segments: authentication modules, protocol translation modules, and data transmission modules. Each segment handles specific tasks independently, allowing for optimized processing at each stage and reducing the complexity burden on any single component. The segmentation enables parallel processing of authentication and translation operations
Data Source
AI summary
A vehicle communication system that provides data between various objects (i.e., devices) within a vehicle communication network is disclosed. In one or more implementations, the vehicle communication system includes an accessor interface module that receives data encoded in an automotive connectivity communication protocol from another accessor module. The other accessor module is associated with an originating object within a vehicle communication network. The data encoded in the automotive connectivity communication protocol includes an object data portion defining a domain associated with a destination object and a payload data portion. The domain has a corresponding authentication protocol for authenticating the data. The accessor interface module authenticates the data according to the authentication protocol. The vehicle communication system also includes an object-specific protocol encoder module that determines an object-specific communication protocol associated with the destination object. The object-specific communication protocol encodes the payload data portion according to the object-specific communication protocol.
