Developing energy-saving and new energy vehicles is an important force driving the next round of scientific and technological revolution and industrial transformation. Hybrid vehicles, with their strong environmental adaptability, diverse energy supply, and high degrees of freedom in energy utilization, will coexist with pure electric vehicles for a long time in the future and are an important support for building a manufacturing powerhouse. After studying the characteristics of hybrid vehicle configurations in depth, this paper analyzes the current status and technological research level of hybrid vehicles in China and abroad. It summarizes the development needs and technical features of hybrid vehicles and focuses on the key technologies of the core components and system integration control of hybrid vehicles. Finally, it puts forward the development suggestions and prospects of hybrid vehicles. This paper can provide support and reference for the development of hybrid vehicle technological routes and policy formulation in China.
