Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle data management systems face complexity when dealing with data from vehicles of varying specifications, models, and manufacturers, leading to inconsistent classification and treatment of similar data types.
Innovation Solution
A vehicle data management device and system that includes a data acquisition unit and a data conversion unit, which acquires vehicle identification information and converts vehicle data into standardized labels and physical values using a conversion map, allowing for consistent classification and analysis across different vehicle models and manufacturers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicle data is classified based on specifications, model year, and manufacturer, then data organization is improved, but database complexity increases and data consistency deteriorates
Solution Approach 1:
The patent introduces a conversion map as an intermediary component that mediates between raw vehicle data and standardized data representations. The conversion map contains conversion information that translates manufacturer-specific data formats into unified standards, allowing the system to maintain simple database structure while handling diverse vehicle data from multiple manufacturers and models without increasing database complexity
Solution Approach 2:
The patent applies parameter changes by transforming data parameters according to vehicle identification information. The conversion map stores conversion information that changes data parameters (such as data types, formats, and representations) based on the specific vehicle manufacturer and model, enabling consistent data treatment while maintaining organized structure without complexity
2Quantity of substance
If vehicle data is accumulated as-is, then data volume is preserved, but data consistency deteriorates due to different identification numbers for same data types
Solution Approach 1:
The conversion map acts as an intermediary that ensures data consistency while preserving data volume. It translates various manufacturer-specific identification numbers and data formats into standardized representations, so that data from multiple vehicles with different specifications are consistently treated as the same data type while maintaining all original data records
Solution Approach 2:
The patent implements universality through the conversion map that serves multiple functions: it handles data conversion, ensures consistency, and maintains data volume. The conversion information in the map enables the system to universally process data from different vehicle manufacturers and models, transforming them into a common standardized format without losing any data
Data Source
AI summary
A vehicle data management device includes a data acquisition unit and a data conversion unit. The data acquisition unit is configured to acquire, from each of a plurality of in-vehicle devices mounted on a corresponding vehicle of a plurality of vehicles, a vehicle identification information that is set based on at least a model of the vehicle, and a first data that is contained in a communication frame and is indicative of a vehicle information. The data conversion unit is configured to convert the first data into a label and a second data based on a conversion map that contains a label identification information for identifying the label corresponding to the first data, and a conversion information for converting the first data into the second data. The conversion map contains at least one label identification information and at least one conversion information for each vehicle identification information.
