Special Issue Information

Dear Colleagues,

Technological advances in artificial intelligence are fundamentally reshaping automotive systems, making them increasingly autonomous, intelligent, and interconnected. In modern vehicles, complex software and data-driven control architectures are now core components that enable advanced functions such as advanced driver-assistance systems (ADASs) and automated driving. While these innovations have played a crucial role in improving future mobility in terms of safety, efficiency, and user experience, significant technical challenges have emerged due to increasing complexity. The greater the complexity of software-intensive automotive systems, the higher the probability of faults occurring in sensors, actuators, and control units, potentially compromising safety-critical functions. Ensuring the safety and reliability of such systems during both manufacturing and operation phases therefore requires advanced fault detection and diagnosis (FDD) methods that go beyond conventional rule- or model-based approaches. These methods should be capable of handling the scale, heterogeneity, and dynamic nature of automotive data.

In recent years, AI-driven approaches for FDD have gained considerable attention from both the scientific community and industry, leading to remarkable progress reported in the literature. Despite these advances, critical challenges remain in terms of the reliability, generalisability, and explainability of such methods, particularly when applied to complex, safety-critical automotive systems.

The aim of this Special Issue is to bring together cutting-edge research contributions that address theoretical developments and innovative engineering applications, as well as advanced tools and platforms for fault detection, isolation, identification, prognosis, and analysis in both conventional and electric automotive systems. We particularly welcome submissions exploring the design and implementation of AI-driven FDD frameworks that leverage machine learning (ML), deep learning (DL), and large language models (LLMs) to enhance the safety, robustness, and efficiency of next-generation automotive technologies during both manufacturing and operation phases. Topics of interest include, but are not limited to, the following:

  • ML- and DL-based methods for fault detection and diagnosis of automotive sensors, actuators, and electronic control units (ECUs).
  • Application of foundation models and LLMs for analysing time-series and multimodal automotive data.
  • Scalable frameworks for FDD in electric, hybrid, and autonomous vehicles.
  • Explainability and interpretability of AI-based diagnostic models.
  • Robustness and safety assurance of AI-driven FDD methods under ISO 26262 and related standards.
  • AI-based behaviour analysis of automotive systems during validation process.
  • Fault-tolerant control and predictive maintenance enabled by AI-driven approach.
  • Benchmarking and comparative studies on real-world automotive datasets.

The growing complexity of software-defined automotive systems generates massive heterogeneous sensor and ECU data during real and virtual validation, and conventional rule-based analysis of such multivariate time series struggles under dynamic operating conditions, noise, and diverse fault scenarios. Deep learning-based anomaly detection has shown promising performance, yet existing approaches remain limited by static thresholds, insufficient robustness, and reduced interpretability. This study proposes an adaptive framework for intelligent fault detection in test recordings of automotive software systems (ASSs), integrating deep denoising autoencoders (DAEs), adaptive Gaussian thresholding, and explainable artificial intelligence (XAI) techniques. Four DAE architectures (ANN-, RNN-, GRU-, and LSTM-DAE) are systematically evaluated under different noise levels, system versions, and fault conditions, with detection thresholds that adapt dynamically to the statistical behavior of the reconstructed signals, thereby reducing false alarms under varying operating conditions. The framework was evaluated using real-world test recordings from IAV and Hardware-in-the-Loop (HIL)-based digital test drives, where ANN-DAE achieved the most robust detection performance, with F1-scores of 93.91% and 96.39% on the real and virtual test-drive data, respectively. Furthermore, the integration of XAI improved the transparency of anomaly interpretation at the signal level. Overall, the proposed framework shows strong potential for intelligent anomaly detection and quality assurance in safety-critical automotive systems. Full article

Soft errors pose a critical reliability threat to deep neural networks in safety-critical systems. We present YOLO-FI, a fault injection framework for YOLO models that supports module-wise analysis, multiple formats, and customizable fault models. Using YOLO-FI, we evaluate YOLOv8 in floating- and fixed-point forms on COCO. Results show that floating-point YOLOv8 is vulnerable across modules, while fixed-point models are resilient except for the final module. Range restriction improves resilience in most floating-point modules but fails in the final one. To address this, we propose selective hardening of the vulnerable module, achieving effective fault mitigation with modest overhead. Full article
