On-Vehicle Device Server Information Collection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information collection systems face increased communication loads and reduced analysis efficiency due to the unnecessary upload of vehicle event data and the mixing of useful and useless data, as the usefulness of vehicle event data depends on various factors such as event type, surrounding circumstances, and analysis purposes.
Innovation Solution
An information collection system comprising an on-vehicle device and a server that transmits a first signal upon detecting a vehicle event, with the server determining whether predetermined information acquisition conditions are met before uploading vehicle event data, thereby reducing unnecessary data transmission and enhancing analysis efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle event data is uploaded to the server every time a vehicle event is detected, then the server receives complete data for analysis, but the communication load increases unnecessarily and analysis efficiency decreases due to mixing useful and useless data
Solution Approach 1:
The server performs preliminary determination of information acquisition conditions before requesting data upload. The server stores predetermined conditions (timing-based information, type information, configuration information) and evaluates them before issuing upload demands, thereby avoiding unnecessary communication loads while ensuring useful data is collected
Solution Approach 2:
The system changes the parameter of data transmission from continuous/upload-on-detection to conditional/upload-on-demand. The server dynamically determines whether to request data based on multiple parameters including timing, event type, and vehicle configuration, thereby optimizing communication efficiency
2Loss of information
If vehicle event data is uploaded every time a vehicle event is detected, then all data is available for analysis, but the server accumulates mixed useful and useless data reducing analysis efficiency
Solution Approach 1:
The server preliminarily determines which data would be useful for analysis by evaluating predetermined information acquisition conditions before requesting upload. This preliminary filtering ensures that only potentially useful data is transmitted to the server, improving analysis efficiency by eliminating useless data from the accumulation process
Solution Approach 2:
The server extracts and evaluates specific parameters (timing-based information, type information, configuration information) from the detected vehicle events to determine whether to request data upload. This extraction process separates useful events from useless ones, ensuring only relevant data is accumulated for analysis
3Reliability
If the system determines usefulness of vehicle event data based on event type, surrounding circumstances, and analysis purposes, then data quality for analysis improves, but the complexity of determining when to upload increases
Solution Approach 1:
The server preliminarily stores and manages predetermined information acquisition conditions including timing-based information, type information, and configuration information. By preparing these determination criteria in advance, the server can efficiently evaluate detected events without complex real-time processing, maintaining data quality while managing system complexity
Solution Approach 2:
The server acts as an intermediary between the on-vehicle device and the analysis process. It receives detection information, evaluates it against predetermined conditions, and selectively requests data upload. This intermediary role simplifies the determination complexity by centralizing the evaluation logic in the server rather than requiring complex local decision-making

AI summary
An information collection system includes an on-vehicle device and a server, wherein the on-vehicle device includes a first transmission signal transmitting part configured to transmit a first transmission signal to the server when the vehicle event is detected, and an upload executing part configured to transmit the vehicle event data to the server when the upload demand is received. The server includes a determining part configured to determine, based on the determination purposes information, when the first transmission is received, whether the information acquisition condition is met, an upload demanding part configured to transmit the upload demand to the on-vehicle device when it is determined that the information acquisition condition is met, and a vehicle event data receiving part configured to receive the vehicle event data transmitted from the on-vehicle device.
