Mobility Service System Digital Twin Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobility service systems face challenges in efficiently acquiring and providing vehicle data, particularly when vehicles are in a power-off state or when data normalization is required, as they either handle low data poorly or are limited to normalized data only, and there is a need for flexible data provision methods.
Innovation Solution
A mobility service providing system comprising an onboard device that collects and spontaneously transmits vehicle data to a server, which also receives requests for data access and provides data to requestors, enabling both direct and cloud-based data acquisition methods, including the use of digital twins for normalized data handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the system only handles normalized data, then data consistency is improved, but data flexibility and adaptability deteriorate
Solution Approach 1:
The patent creates a digital twin copy of the vehicle that replicates the vehicle's state, events, and data in a virtual environment. This copy allows the system to access and provide data regardless of the actual vehicle's operational state, enabling both consistent normalized data representation and flexible adaptation to different data access scenarios (real-time, historical, normalized, raw).
Solution Approach 2:
The digital twin serves as an intermediary between the physical vehicle and the data access system. It mediates the interaction by providing a standardized virtual representation that can be accessed consistently while also enabling flexible data retrieval methods (direct access, normalized access, historical access) without requiring the actual vehicle to be in a specific state.
2Reliability
If the system waits for vehicle data transmission, then data completeness is improved, but response time deteriorates
Solution Approach 1:
The digital twin continuously maintains a virtual copy of the vehicle's state and events, performing preliminary data collection and storage before actual data requests are made. This allows the system to provide immediate responses for both real-time and historical data access without waiting for the vehicle to transmit data, while still maintaining data completeness through continuous updates of the digital twin.
3Adaptability or versatility
If the system provides both real-time and historical data, then data versatility is improved, but system complexity increases
Solution Approach 1:
The digital twin provides a universal interface that handles multiple data access scenarios through a single unified system. It can provide real-time data, historical data, normalized data, and raw data through the same digital twin structure, eliminating the need for separate systems for each data type and reducing overall system complexity despite increased versatility.
Data Source
AI summary
When an interface unit has received a first access request, first control units acquire vehicle data from storage units, and provide the vehicle data to a request source through an interface unit. When the interface unit has received a second access request, a second control unit acquires the access result including the vehicle data from a vehicle-mounted machine by accessing the vehicle-mounted machine, and provides the access result to the request source through the interface unit.
