Vehicle Data Collection by Use-Purpose for Leaner Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle data collection systems waste resources by transmitting unnecessary data, leading to increased memory and power consumption in both vehicles and center devices, without optimizing data transmission based on the purpose of vehicle use.
Innovation Solution
A vehicle data collection device that collects and discriminates vehicle data based on purpose of use using an analysis model, storing and transmitting only necessary data to a center device, thereby reducing unnecessary data transmission and resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all vehicle data is transmitted to the center device, then data completeness is improved, but memory consumption and power consumption increase
Solution Approach 1:
The patent extracts and transmits only the necessary vehicle data to the center device based on the determined purpose of use, rather than transmitting all collected data. This selective extraction reduces the volume of transmitted data, thereby lowering power consumption and memory usage while maintaining data completeness for the specific application purpose.
Solution Approach 2:
The patent applies different data transmission strategies based on the local quality or characteristics of the data and its relevance to the purpose of use. By analyzing the purpose of use and determining which data items are necessary, the system applies selective transmission quality levels to different data types, optimizing the balance between data completeness and resource consumption.
2Loss of information
If all vehicle data is transmitted to the center device, then data completeness is improved, but memory consumption increases
Solution Approach 1:
The system extracts only the necessary data items from the collected vehicle data based on the determined purpose of use. By removing unnecessary data before transmission and storage at the center device, the memory consumption is reduced while maintaining data completeness for the specific application purpose.
3Ease of operation
If unnecessary data is transmitted, then resource consumption increases, but data transmission simplicity is maintained
Solution Approach 1:
The patent performs preliminary determination of the purpose of use and identifies necessary data items before the actual data transmission occurs. This preliminary action of filtering and selecting data in advance simplifies the transmission process by pre-processing the data, while simultaneously reducing resource consumption by eliminating unnecessary data from the transmission pipeline.

AI summary
A data collector collects types of vehicle data. An analysis model represents a correspondence between a tendency and a purposes of use of a vehicle. In a correspondence table, selected data, which is a part of the types of vehicle data to be collected for each of the purposes of use, is associated with the purpose of use. A data accumulator accumulates the types of vehicle data collected in a certain period in the past. A purpose discriminator discriminates the purpose of use using the analysis model and the types of vehicle data accumulated in the data accumulator. A storage controller causes a transmission data storage to store the selected data to be transmitted to a center device identified using the correspondence table and based on the discriminated purpose of use. A transmission controller transmits the stored selected data to the center device at a set transmission frequency.
