Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real vehicle operation is used to generate telematics data for testing, then data authenticity is improved, but time consumption and operational complexity increase significantly
Solution Approach 1:
The patent creates a simulated vehicle environment that generates telematics data copies identical in format and structure to real vehicle data. The simulation system replicates vehicle states, sensor readings, and event sequences without requiring actual vehicle operation, thus maintaining data authenticity while eliminating time-consuming physical testing
Solution Approach 2:
The system performs preliminary data generation through simulation before actual testing begins. By pre-generating realistic telematics data scenarios including edge cases and failure modes, the system eliminates the need for extensive real-world driving tests, significantly reducing time consumption while maintaining data quality
2Adaptability or versatility
If real vehicle operation is used to generate telematics data, then data coverage across vehicle states is improved, but operational complexity and resource requirements increase
Solution Approach 1:
The simulation system dynamically transitions between various vehicle states (idle, cruising, acceleration, deceleration, parking) through controlled parameter adjustments. This allows comprehensive coverage of all possible vehicle operating conditions without the operational complexity of physically maneuvering a real vehicle through each state
Solution Approach 2:
The simulated vehicle environment serves multiple functions simultaneously: it generates telematics data, simulates various vehicle states, creates test scenarios, and provides a controlled testing platform. This multi-functionality achieves comprehensive data coverage while reducing operational complexity compared to using actual vehicles
3Measurement precision
If physical vehicle testing is used for application development, then testing accuracy is improved, but cost and time resources increase
Solution Approach 1:
The system creates accurate digital copies of vehicle telematics data that preserve all measurement precision and data characteristics of real vehicle operation. Developers can test applications against these simulated data copies with the same accuracy as real-world testing, while achieving significantly higher development productivity through automated simulation
Solution Approach 2:
The simulation system prepares test data and scenarios in advance, allowing developers to conduct comprehensive application testing before deploying to real vehicles. This preliminary testing phase maintains measurement precision while dramatically improving development efficiency by identifying and resolving issues in the virtual environment
Data Source
AI summary
Simulation of vehicle telematics events is provided by a vehicle telematics simulator. The simulator performs a simulation of vehicle telematics events based on user-defined parameters to generate simulation data. The simulation data is formatted according to a reporting protocol to obtain formatted simulation data. The reporting protocol may be the same reporting protocol used by vehicle-based telematics devices to format and report measurement data for real-world vehicle telematics events. The formatted simulation data is provided to a vehicle telematics service hosted at a server system for processing. The formatted simulation data is processed along with formatted measurement data representing measurements of real-world telematics events via a common processing pipeline of the vehicle telematics service. The vehicle telematics simulator may reside at a client computing device or at the server system that hosts the vehicle telematics service.
