Abstract:　In the 21st century，world demand for energy than any other time in history more than the energy shortage problem has become a troubled world，how under the premise of protecting  the  environment  to  meet  the  energy  needs  of  the  people  has  become  an important research topics. Car，as an energy-intensive machine，thus the need for technical innovation, also came into being all kinds of new energy vehicles. Developing the new energy vehicles，hybrid vehicles，more energy-efficient conventional cars has become a global automotive industry consensus. All the world’s largest car manufacturers have a huge variety of new hybrid research and development resources, energy-saving technologies.

Hybrid cars hybrid system is the key，its performance is directly related to vehicle performance hybrid cars. After ten years of development，hybrid system motors and motor assembly from the discrete structure of the original engine motor and gearbox to the development of integrated structure that integrated hybrid powertrain system.

　　　In this paper, the research on hybrid vehicles, hybrid vehicles described current problems and research progress. The concept of hybrid vehicles, classification and principles  of  analysis  of  the  latest  energy-saving  hybrid  vehicle  technology  are expounded. The world’s major automobile manufacturers of advanced energy-saving technology of hybrid cars are introduced. Hybrid vehicles and energy-saving technology development prospects is discussed.
