Digital Vehicle Key Protocol Bridging for Terminal Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing digital vehicle key solutions face compatibility issues due to restrictions on terminal devices, as they require specific public protocols, limiting user experience and increasing development and deployment costs, as not all terminal devices support the same public protocols, preventing seamless key sharing and vehicle control across different manufacturers.
Innovation Solution
A terminal device equipped with a communication device that detects the absence of native system components for adapting a public protocol and communicates with a target communication party based on the public protocol, enabling the implementation of digital vehicle key functions even on devices without native support, using protocols like ICCOA, CCC, or ICCE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital vehicle key solutions require specific public protocols in the native system, then security and protocol compliance are improved, but compatibility across different terminal devices deteriorates
Solution Approach 1:
The patent introduces a virtual machine as an intermediary layer between the public protocol requirements and the terminal device's native system. When the native system lacks required components, the virtual machine provides them, enabling protocol compliance without modifying the underlying native system. This mediator approach allows digital vehicle key functions to run on diverse terminal devices while maintaining security and protocol standards.
2Adaptability or versatility
If private protocol configurations are implemented to ensure compatibility, then adaptability across devices is improved, but development and deployment costs increase
Solution Approach 1:
The patent creates a universal virtual machine solution that can execute digital vehicle key protocols across different terminal devices regardless of their native system capabilities. Instead of developing separate private protocol implementations for each device type, the virtual machine provides a unified platform that handles protocol adaptation, reducing overall system complexity and development costs while maintaining broad compatibility.
3Reliability
If native system components are required for public protocol adaptation, then protocol implementation reliability is improved, but device complexity and deployment requirements increase
Solution Approach 1:
The virtual machine acts as a mediator that packages required protocol components into a self-contained environment. Instead of requiring the terminal device's native system to have specific components installed, the virtual machine brings its own implementation of necessary components, simplifying deployment requirements while ensuring reliable protocol implementation.

AI summary
A terminal device includes a communication device, configured to detect whether a native system of the terminal device includes components for adapting a public protocol of a digital vehicle key, and communicating with a target communication party based on the public protocol in case of absence of at least one of the components in the native system, in which the target communication party is a participant of the public protocol.
