In-Vehicle ITS Service Integration Using Trusted Mobile Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent transportation systems (ITS) face limitations in bandwidth and hardware resources, leading to insufficient capacity for implementing advanced services and features, particularly in vehicles not originally designed to support these services, resulting in degraded transportation experience and safety risks due to reliance on external data sources.
Innovation Solution
Utilizing a mobile communication device connected to the vehicle's ITS system to provide additional services and data, with a processor selectively identifying and authorizing the use of service information elements based on risk metrics and trustworthiness, ensuring safe integration of external data for critical vehicle functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external data sources are used to provide additional services, then service capacity is improved, but safety and reliability deteriorate due to trust risks
Solution Approach 1:
The patent introduces a mobile communication device as an intermediary between external data sources and the vehicle's ITS system. This intermediary performs trust evaluation and data filtering, allowing the system to access external services while maintaining safety through selective data authorization based on risk metrics
Solution Approach 2:
The system performs preliminary trust evaluation and risk assessment on external data sources before integrating their services. By pre-authorizing data sources based on their trustworthiness metrics, the system ensures that only reliable external data is used, preventing safety issues before they occur
2Device complexity
If vehicles not originally designed for advanced services are used, then device complexity is reduced, but service functionality deteriorates
Solution Approach 1:
The mobile communication device serves multiple functions: it acts as a communication interface, a trust evaluation engine, a data filtering system, and a service authorization manager. This single universal device enables advanced ITS services in vehicles without dedicated hardware, making the system multi-functional without increasing vehicle complexity
Solution Approach 2:
The system uses the mobile communication device's existing capabilities and resources to provide ITS services, rather than requiring the vehicle to have specialized hardware. The mobile device leverages its own processing power, communication interfaces, and data processing abilities to serve the vehicle's ITS needs
3Reliability
If comprehensive data filtering and authorization is implemented, then safety is improved, but processing time and system complexity increase
Solution Approach 1:
The system implements selective data filtering and authorization rather than comprehensive processing of all external data. By focusing trust evaluation and risk assessment only on critical service information elements and authorized data sources, the system maintains high safety standards while reducing unnecessary processing time
