Predictive maintenance enabled by machine learning: Use cases and challenges in the automotive industry

Recent developments in maintenance modelling fuelled by data-based approaches such as machine learning (ML), have enabled a broad range of applications. In the automotive industry, ensuring the functional safety over the product life cycle while limiting maintenance costs has become a major challenge. One crucial approach to achieve this, is predictive maintenance (PdM). Since modern vehicles come with an enormous amount of operating data, ML is an ideal candidate for PdM. While PdM and ML for automotive systems have both been covered in numerous review papers, there is no current survey on ML-based PdM for automotive systems. The number of publications in this field is increasing - underlining the need for such a survey. Consequently, we survey and categorize papers and analyse them from an application and ML perspective. Following that, we identify open challenges and discuss possible research directions. We conclude that (a) publicly available data would lead to a boost in research activities, (b) the majority of papers rely on supervised methods requiring labelled data, (c) combining multiple data sources can improve accuracies, (d) the use of deep learning methods will further increase but requires efficient and interpretable methods and the availability of large amounts of (labelled) data.

Automated summary

Recent advancements in maintenance modeling, particularly driven by data-based approaches like machine learning, have led to a wide range of applications in various industries. In the automotive sector, ensuring functional safety and optimizing maintenance costs has become a significant challenge. The lack of current surveys on ML-based predictive maintenance for automotive systems highlights the importance of understanding this emerging field. Key findings suggest that the availability of public data can boost research activities, combining multiple data sources can enhance accuracy, and the use of deep learning methods is expected to rise further.
