Abstract
With the escalating global energy crisis and environmental issues, vehicle energy-saving technologies have become a crucial research direction for sustainable development in the transportation sector. This study aims to investigate various vehicle energy-saving technologies and their energy efficiency evaluation methods, providing a scientific basis for enhancing vehicle energy utilization efficiency. By integrating theoretical analysis, experimental validation, and simulation modeling, this research delves into key technologies such as the optimization of hybrid power system control strategies, the application of lightweight materials, and aerodynamic improvements, while proposing an energy efficiency assessment model based on a multi-criteria evaluation system. This model, incorporating real-world operating condition data, can more accurately reflect the comprehensive performance of different energy-saving technologies under complex operational scenarios. The results indicate that through the synergistic optimization of multiple energy-saving technologies, vehicle energy consumption can be significantly reduced, along with emissions. Moreover, the proposed evaluation method demonstrates greater universality and accuracy compared to traditional single-indicator approaches. A primary innovation of this study lies in the construction of an integrated evaluation fr amework that encompasses technical performance, economic cost, and environmental benefits, offering new insights for the selection and promotion of energy-saving technologies and laying a foundation for relevant policy formulation and technical standard refinement.
