Abstract
With the rapid development of modern transportation systems, vehicle fault diagnosis and health management have become critical approaches to enhancing transportation efficiency and safety. This study proposes an integrated vehicle fault diagnosis and health management system based on big data technology, aiming to achieve comprehensive monitoring and precise evaluation of vehicle operating conditions through real-time data acquisition, analysis, and prediction. A multi-source sensor data fusion method is employed in conjunction with machine learning algorithms and deep neural network models to construct an efficient fault feature extraction and classification fr amework. Additionally, a health index assessment system is introduced to quantify the degree of vehicle performance degradation. Experimental results demonstrate that the system can accurately identify various typical fault patterns, achieving a diagnostic accuracy of over 95%, while also exhibiting strong generalization capabilities and real-time advantages. Furthermore, the system supports long-term trend forecasting, providing a scientific basis for preventive maintenance. The primary innovation of this research lies in the deep integration of big data analytics with traditional diagnostic techniques, overcoming the limitations of single data sources and significantly improving the reliability and intelligence level of diagnostics. The research findings not only offer new insights into vehicle operation and maintenance management but also broaden the application prospects in the field of condition monitoring and health management for complex equipment.
