Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current method of transmitting data from vehicle driver assistance systems to an external backend computer using the pull principle results in high query volumes, increased latency, and data protection challenges due to continuous data reporting and direct GPS position sharing.
Innovation Solution
Implementing a method where ADAS data is stored in a vehicle-side swarm data aggregator, summarized, and transmitted only when needed, with anonymization and analysis triggered by a parameterizable analysis algorithm, reducing data transfer volume and optimizing data protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous data reporting and direct GPS position sharing are used, then data availability and real-time monitoring are improved, but data transfer volume and latency increase
Solution Approach 1:
The system pre-processes and stores ADAS data in a vehicle-side swarm data aggregator before external requests occur. This preliminary action allows the backend computer to quickly retrieve and analyze relevant data without waiting for continuous real-time reporting, thereby reducing latency while maintaining data availability.
Solution Approach 2:
The patent extracts only the necessary GPS position information and specific ADAS data relevant to the analysis request, rather than transmitting all continuous data streams. This selective extraction reduces data transfer volume and processing latency while preserving the reliability needed for safety-critical analysis.
2Adaptability or versatility
If all ADAS data is transmitted to the backend computer, then comprehensive analysis capability is improved, but data transfer volume and processing load increase
Solution Approach 1:
The system applies local quality by storing and pre-processing different types of ADAS data (geoinformation, traffic data, event data, status data) with different levels of detail and retention periods based on their specific characteristics and potential analytical value. This allows comprehensive analysis capability while optimizing data transfer volume by only transmitting relevant data.
Solution Approach 2:
The patent segments ADAS data into four distinct categories (geoinformation, traffic data, event data, status data) with different storage and transmission characteristics. This segmentation enables selective transmission of only the data segments relevant to specific analysis requests, reducing overall data transfer volume while maintaining comprehensive analysis capability when needed.
3Ease of operation
If GPS position data is shared directly with external users, then location-based service quality is improved, but data protection and privacy security worsen
Solution Approach 1:
The backend computer acts as an intermediary between the vehicle's GPS position data and external users. It receives position information, processes it in the context of safety-critical analysis needs, and provides location-based services without directly exposing raw position data to external users. This maintains service quality while protecting privacy through controlled mediation.
4Speed
If data is stored in vehicle-side swarm data aggregator with decay time, then fast reaction time is achieved, but data retention period is limited
Solution Approach 1:
The system implements dynamic data retention with decay time, where data is stored in the vehicle-side swarm data aggregator for a limited period and automatically removed after expiration. This dynamic approach enables fast reaction times for recent events while managing storage resources efficiently, and allows historical analysis by retrieving data from multiple vehicles' aggregators as needed.
