Vehicle Onboard Modules Sharing Services for Toll System Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Complex applications like toll systems in electronic vehicle on-board systems face challenges due to high communication bus load and additional validation and certification efforts when integrating third-party modules, leading to inefficiencies and difficulties in verifying and certifying their functionality.
Innovation Solution
Modularizing services into individual service modules that can be shared by multiple application modules, with a recording module connected to the communication bus to detect and record requests and responses, providing a signature for authenticity and enabling easy verification and certification of the toll application and its service modules, allowing for efficient integration and testing of complex applications like tolling and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex applications like toll systems are integrated as separate devices, then functionality is provided, but communication bus load increases and validation/certification effort increases
Solution Approach 1:
The patent merges the toll application with the vehicle's existing on-board system by integrating it as a module within the system rather than as a separate device. This consolidation allows the toll application to share communication resources and validation infrastructure with other vehicle functions, thereby providing the required functionality while avoiding the additional communication bus load and certification overhead that would result from a completely separate device integration
2Adaptability or versatility
If third-party service modules are integrated, then application functionality increases, but validation and certification effort increases
Solution Approach 1:
The patent segments the on-board system into modular service modules, each with defined interfaces and responsibilities. This segmentation allows third-party service modules to be integrated in a standardized manner, where the modular architecture and interface specifications provide a framework for validation and certification that reduces the overall effort compared to integrating non-modular third-party components
3Adaptability or versatility
If multiple application modules are added, then system functionality increases, but load on communication bus increases
Solution Approach 1:
The patent implements a universal service module architecture where service modules can be shared by multiple application modules. This multi-functionality allows different applications to access common services through the same communication interfaces and protocols, thereby increasing system functionality while avoiding the proportional increase in communication bus load that would result from dedicated communication paths for each application
