Abstract:

Transmission technology is the key of the vehicle powertrain. The development of energy-saving vehicle and new energy resource vehicles posed new challenges to the transmission technology. Based on energy-saving vehicle and new energy resource vehicle technology roadmap, the requirement of the traditional internal combustion vehicles, hybrid vehicle (HEV) and plug-in hybrid vehicle (PHEV), pure electric vehicle (EV) on the transmission system side were proposed, and the development of the transmission industry in Mainland China was also described. The characteristics of different types of automatic transmission was analyzed. The development direction of multi-shift, wide speed ratio, lighting weight, high power density, high efficiency and
continuous optimization was described. The types of HEV/PHEV configuration schemes and their respective characteristics were introduced. The advantages and disadvantages of typical configuration schemes and the development of HEV/PHEV control technologies were analyzed. Finally, the development of centralized electric drive and distributed electric drive technology was introduced.
