Dataset and MATLAB Scripts for Recurrence-Based Diagnostics of Electric Parking Brake (EPB) Modules

This dataset contains vibration-based diagnostic data and MATLAB scripts used in the study: "Non-Destructive Diagnostics of Electric Parking Brake Modules Using Recurrence Analysis of Piezoelectric Sensor Data". The dataset includes: - Data corresponding to five predefined failure modes of the EPB system: (1) missing gear (lower row), (2) missing gear (upper row), (3) tooth damage, (4) timing belt damage, (5) incorrect gear installation. - Extracted Recurrence Quantification Analysis (RQA) features (DET, LAM, Lmax, L, TT, Vmax) for multiple sensor locations. - MATLAB scripts used for computation of RQA statistics and generation of plots presented in the manuscript. The RQA feature files correspond directly to the defined failure modes and allow reproduction of the statistical results reported in the study.
