In-Vehicle Networks & Onboard Cybersecurity
Anomaly detection in CAN, Ethernet, and FlexRay networks is critical for cybersecurity, detecting protocol violations, timing deviations, and message inconsistencies. Approaches combine statistical features, sequence models (like LSTM), and physical-layer fingerprinting to ensure robust intrusion detection.
Manufacturing Systems & Offboard Cybersecurity
Monitoring manufacturing processes for anomalies ensures quality and operational efficiency. This includes detecting irregularities in production lines, robot behavior, and network security threats. Hybrid and unsupervised deep learning methods are key due to data heterogeneity and scarcity of labeled anomalies.
In-Vehicle Sensors & Subsystems
Anomaly detection in sensors (e.g., radar, LiDAR, IMU) and vehicle subsystems (powertrain, braking) is vital for autonomous driving and predictive maintenance. Temporal models, reconstruction-based detectors, and real-time lightweight solutions are employed to identify sensor drifts, intermittent faults, and actuator deviations.
EV Charging Infrastructures & Grid Anomalies
With the rise of EVs, detecting anomalies in charging stations and the integrated power grid is paramount. This involves identifying irregular load profiles, hardware degradation, power quality issues, and cyber intrusions. Lightweight, scalable, and hybrid models are used to ensure grid stability and charger reliability.

Case Study: Benchmarking Real-Vehicle Attacks with ROAD Dataset
The ROAD (Real-Vehicle On-road Anomaly Detection) dataset, developed by ORNL, is a critical benchmark for evaluating automotive anomaly detection systems against stealthy, real-vehicle attacks. Unlike traditional datasets that might focus on specific attack types, ROAD provides a comprehensive environment to test detectors for robustness against sophisticated, real-world intrusions.
Its emphasis on PR-centric metrics (Average Precision, FPR@95%) ensures that evaluation accurately reflects performance on highly imbalanced data, prioritizing the detection of rare but critical anomalies. This addresses a key challenge in automotive AI: ensuring reliable detection without excessive false positives in a safety-critical context, pushing the industry towards more robust and generalizable solutions for connected and autonomous vehicles.
