Solution Overview
Problem
Existing systems for collecting driving event data in motor vehicles face challenges in efficiently transmitting accurate and detailed information due to limited transmission bandwidth and cost constraints, requiring a balance between data volume and description accuracy.
Innovation Solution
A method where a stationary server device generates configuration data based on initial event data from a first motor vehicle, reconfiguring a second motor vehicle's detection apparatus to generate more detailed second event data, optimizing data transmission by utilizing available bandwidth only when necessary and focusing on relevant surroundings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detection apparatus is configured to generate detailed event data, then measurement precision is improved, but data transmission volume increases beyond available bandwidth
Solution Approach 1:
The patent segments the data collection process into multiple phases: initial coarse detection with minimal data transmission, followed by selective detailed measurement only for relevant events. This divides the continuous data stream into hierarchical levels of detail, transmitting only essential information continuously while reserving detailed data for specific cases.
Solution Approach 2:
The system performs preliminary detection using basic sensors to identify potential driving events before committing resources to detailed measurement. This preliminary action filters out irrelevant data early, preventing unnecessary detailed measurements and reducing overall data transmission volume while maintaining measurement precision for actual events.
2Measurement precision
If detection apparatus is configured to generate detailed event data, then measurement precision is improved, but transmission costs increase
Solution Approach 1:
The patent segments data transmission into two cost categories: low-cost continuous transmission of minimal event signals, and high-cost selective transmission of detailed data only when necessary. This segmentation optimizes the balance between measurement precision and transmission cost by minimizing expensive data transfers.
Solution Approach 2:
The system applies partial action by transmitting only the minimum necessary data continuously, and adding detailed information partially only when driving events are detected. This avoids the excessive action of continuously transmitting full-detail data, reducing transmission costs while maintaining measurement precision for relevant events.
3Measurement precision
If all motor vehicles continuously transmit detailed event data, then measurement precision is improved, but transmission bandwidth is exceeded
Solution Approach 1:
The patent merges data collection efforts across multiple vehicles by having them transmit minimal data to a central server, which then coordinates detailed measurements. This combining approach allows the system to achieve comprehensive coverage and high measurement precision without each vehicle independently consuming full bandwidth, improving overall transmission efficiency.
Solution Approach 2:
Vehicles perform preliminary detection and transmit only essential information continuously. The server uses this preliminary data to identify which vehicles should perform detailed measurements, preventing all vehicles from simultaneously transmitting detailed data and exceeding bandwidth limits, thus maintaining transmission efficiency.

AI summary
A method is disclosed for measuring a driving event, a server device receiving first event data from a first motor vehicle, which first event data signal the driving event identified by a first detection apparatus of the first motor vehicle. The method further provides that the server device generates configuration data on a basis of the first event data in order to configure a second detection apparatus of a second motor vehicle that is different from the first detection apparatus of the first motor vehicle and sends the configuration data to the second motor vehicle in order to generate second event data that describe the driving event.
