Outlier Detection in Racing Car Telemetry Data as a Fault Diagnosis ToolThe present Master’s Thesis aims to develop a methodology for anomaly detection in motorsport telemetry data, with the objective of identifying abnormal behaviours that may be associatedwith mechanical failures. Based on real data recorded by the acquisition system of the Ligier JS2Rvehicle, various physical signals related to the engine, gearbox and driving behaviour have beenanalysed using unsupervised machine learning techniques.The study focuses on the analysis of a real failure that occurred during a race — the explosionof the gearbox oil radiator. Since there were no labels indicating the exact moment of failure, an unsupervised learning approach was adopted. Furthermore, due to the temporal nature of telemetrydata, the project relies on multivariate time-series techniques, which make it possible to modelthe normal behaviour of the vehicle and detect significant deviations. To this end, four anomalydetection methods were implemented and compared: Hierarchical Temporal Memory, Matrix Profile, Unsupervised Anomaly Detection, and Anomaly Detection with CorrelationAnalysis.The results confirm the ability of the models to identify the moments in which the behaviourof the variables deviates from normal conditions, highlighting gearbox oil pressure (gsp) as thevariable most strongly associated with the failure. In addition, the alterations observed in engineand driver-related variables reveal the dynamic consequences of the incident.Finally, this work lays the foundation for the future development of an interactive tool thatwill allow engineers to visualise detected anomalies along the vehicle’s track or by laps, therebyfacilitating post-session diagnostics. Despite certain limitations — such as the absence of spatialinformation and the need to expand the database of failure cases to obtain a more comprehensivetool - the proposed methodology demonstrates strong potential to become a support system fordata analysis in competitive racing environments.
