This study explores the use of wavelet-based analysis for evaluating vehicle ride comfort through vibration signal processing. Using a custom-developed Android application, three-axis accelerometer and GPS data were collected under real driving conditions to identify three categories passenger experience: comfortable, vibrationally uncomfortable, oscillatory uncomfortable. The signals decomposed using Daubechies wavelet (Db2) up level 8, feature extraction was conducted detail coefficients. Significant differences between types observed time frequency domain analyses, with enhanced discrimination achieved via decomposition RMS-based quantification. results highlight that uncomfortable exhibit highest coefficient values, clearly differentiating them from other two categories. findings confirm methods provide improved insights into characteristics, enabling more precise classification discomfort. work establishes foundation real-time monitoring future applications in transportation safety healthcare, particularly context patient transport.
