Vehicle Driver Profile Sync With Dual Storage and Timed Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing individual characteristics management systems struggle to obtain detailed individual characteristics while minimizing the processing load on vehicles, often requiring extensive communication between vehicles and servers.
Innovation Solution
The system employs a dual-storage approach with a first storage installed in the vehicle and a second storage external to the vehicle. The controller updates both data sets based on the driving state, with updates to the first data occurring during driving and updates to the second data happening when the vehicle is stopped, transmitting only the data updated during driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed individual characteristics are estimated by computation at an external server, then measurement precision of individual characteristics is improved, but device complexity and processing load at the vehicle side increase due to large amount of communication
Solution Approach 1:
The patent segments the data storage and processing functions between two locations: first storage (local vehicle storage) and second storage (external server storage). This segmentation allows the system to maintain detailed individual characteristics data externally while providing essential data locally, thereby improving estimation accuracy without requiring constant communication during vehicle operation.
Solution Approach 2:
The system performs preliminary actions by updating the first storage with essential individual characteristics data before the vehicle operates. This preliminary data preparation enables the vehicle to function with reduced communication needs, while the external server maintains comprehensive data for accurate estimation when the vehicle is not in use.
2Quantity of substance
If all data relating to individual characteristics is stored at the exterior of the vehicle, then storage capacity is improved, but processing load and response time at the vehicle increase
Solution Approach 1:
The patent divides data storage into two segments: first storage located in the vehicle for essential data requiring fast access, and second storage located externally for comprehensive data. This segmentation enables the system to maintain large data capacity externally while ensuring rapid access to critical individual characteristics data during vehicle operation.
3Productivity
If communication between vehicle and server is minimized, then processing load at vehicle side is reduced, but update frequency of individual characteristics data decreases
Solution Approach 1:
The system implements periodic action by updating the external second storage with comprehensive individual characteristics data at regular intervals when the vehicle is not in use. This periodic update mechanism ensures data timeliness and accuracy while minimizing communication interference with vehicle operations, thereby maintaining both processing efficiency and information freshness.
