In-Vehicle Incident Detection for Automated Driving Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle incident monitoring technologies fail to reliably and quickly detect anomalies, especially when a vehicle is driving in a manner similar to a general drive pattern, even if an incident has occurred.
Innovation Solution
An in-vehicle device equipped with an incident detection processing unit that acquires vehicle information and detects incidents based on this information, utilizing a network system comprising a vehicle, roadside unit, and center server to rapidly identify and respond to potential cyber threats or anomalies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anomaly detection is performed by comparing vehicle drive information with general drive patterns, then detection can be performed using available data, but incidents cannot be detected when the vehicle is driving in a manner close to general drive patterns
Solution Approach 1:
The patent segments the monitoring system into multiple independent components: an incident information acquisition unit that collects data from multiple ECUs, an incident detection unit that analyzes the data, and a safety control unit that executes responses. This segmentation allows each component to specialize in specific tasks, improving overall detection reliability without being constrained by general drive pattern comparisons.
Solution Approach 2:
The patent introduces an intermediary monitoring system that sits between the ECU network and the vehicle control systems. This intermediary acquisition unit collects incident information from multiple ECUs independently of the normal drive pattern flow, enabling detection of anomalies even when vehicle behavior appears normal. The intermediary layer acts as a buffer that can identify subtle deviations without disrupting normal operation.
2Device complexity
If general-purpose devices and programs are used in information communication equipment, then system complexity is reduced, but the risk of cyberattacks increases
Solution Approach 1:
The patent implements preliminary safety measures by continuously monitoring for incidents before they can compromise the system. The incident detection unit proactively identifies potential cyber threats by analyzing data from multiple ECUs, enabling the safety control unit to deactivate automated driving functions or alert the driver before a cyberattack can cause harm. This preliminary detection approach mitigates cyberattack risks while maintaining the use of general-purpose devices.
Solution Approach 2:
The patent creates a protective buffer layer through the incident monitoring system that cushions the vehicle control systems against cyberattacks. By continuously acquiring incident information from multiple ECUs and analyzing it through the detection unit, the system prepares safety responses in advance, such as deactivating automated driving functions or triggering driver alerts, thereby cushioning the impact of potential cyber threats before they can propagate through the system.
Data Source
AI summary
An in-vehicle device is mounted on a vehicle capable of automated driving, and comprises an incident detection processing unit which acquires vehicle information representing a control state of the vehicle, and detects an incident that occurred in the vehicle based on the vehicle information.
