In-Vehicle Anomaly Notification Using Code Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anomaly detection systems in vehicles struggle with inappropriate output of anomaly notifications due to high false detection rates, making it difficult to distinguish between actual attacks and false alarms, especially when multiple events are detected over time.
Innovation Solution
An analysis device that collects and analyzes log information from in-vehicle devices, applies immediate and predictive notification rules, and utilizes code verification results to determine the timing and type of anomaly notifications, reducing false detections by integrating log analysis, attack detection, and notification control units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple separate analysis devices are used to measure different parameters (glucose, cholesterol, uric acid), then measurement precision for each parameter is maintained, but device complexity and space requirements increase significantly
Solution Approach 1:
The patent combines multiple independent analysis devices into a single integrated device. Each device measures a different parameter (glucose, cholesterol, uric acid) using its own sensor and reagent system. By merging these separate devices into one unified system with a common controller and display, the patent reduces device complexity and space requirements while maintaining the measurement precision of each individual parameter through dedicated sensors and reagents.
2Measurement precision
If multiple separate analysis devices are used to measure different parameters, then measurement precision for each parameter is maintained, but the space required for all devices increases
Solution Approach 1:
The patent consolidates multiple analysis devices that would otherwise occupy separate spaces into a single integrated unit. The device includes multiple sensors, reagent containers, and measurement chambers arranged within one compact housing, significantly reducing the total space required while maintaining the ability to perform precise measurements for each parameter through dedicated sensor-reagent pairs.
3Ease of manufacture
If conventional reagents are used without protective coatings, then ease of manufacture is maintained, but bacterial contamination and reagent degradation occur
Solution Approach 1:
The patent introduces a protective coating as an intermediary layer between the conventional reagents and the external environment. This coating, applied to the reagent-containing structures, prevents bacterial contamination and reagent degradation without requiring changes to the reagent formulation itself. The coating acts as a barrier that maintains reagent integrity while allowing the manufacturing process to remain simple and compatible with conventional reagents.

AI summary
Provided is an analysis device that reduces false detection of an attack event to appropriately output an anomaly notification. The analysis device configured to be communicable with a plurality of monitoring-target devices collects monitoring results of each of the monitoring-target devices, determines whether an anomaly has occurred in each of the monitoring-target devices, based on the monitoring results, and determines whether to output an anomaly notification indicating the anomaly, based on a result of the determination and code verification results of each of the monitoring-target devices.
