Abstract
As global energy crises and environmental pollution become increasingly severe, the development of new energy vehicles has emerged as a critical approach to addressing these challenges. Plug-in hybrid electric vehicles (PHEVs), which combine the advantages of conventional internal combustion engine vehicles and pure electric vehicles, hold significant potential for reducing emissions and improving energy efficiency. The energy recovery system is one of the key technologies for enhancing overall vehicle efficiency and extending driving range. This study focuses on the optimization design and performance improvement of the energy recovery system in PHEVs, aiming to develop an efficient and intelligent energy recovery strategy. By establishing vehicle dynamics models and motor operation characteristic models, this research integrates rule-based control algorithms with fuzzy logic control to achieve precise control of energy recovery during braking processes. Experimental results demonstrate that the proposed energy recovery system effectively increases the utilization rate of braking energy, reducing overall vehicle energy consumption by approximately 15% under urban driving conditions, while significantly enhancing driving comfort and safety. Innovatively, this study introduces multi-ob jective optimization algorithms, achieving an optimal balance between energy recovery efficiency and ride experience. This research provides theoretical foundations and technical support for the practical application of energy recovery systems in PHEVs, contributing significantly to the advancement of the new energy vehicle industry.
