As the development of new energy vehicles deepens, hybrid vehicles have emerged as a relatively rapidly expanding market segment, and Original Equipment Manufactures(OEMs) have augmented their investment in the research and development of hybrid vehicles and hybrid drive units. To develop hybrid drive units more efficiently,the main concept and classification of hybrid vehicles and hybrid drive system are introduced from component composition, structure and motor position.Based on the drive system types of hybrid models in the China market in 2024, the application status of different configuration of hybrid drive systems is described in detail.And based on the development history of hybrid drive units of automobile companies such as Toyota, Honda, General Motors, SAIC and BYD, the iterative process of the hybrid drive unit is systematically sorted out, and the future development trend of the hybrid drive unit is ultimately prospected, so as to provide a reference for enterprises to develop hybrid drive units with independent intellectual property rights.
