Abstract: This paper introduces the application of hybrid power technology in vehicles. It analyzes the characteristics
of vehicles and hydraulic hybrid vehicles and mainly focuses on the hydraulic hybrid vehicles. A comprehensive sum-
mary of hydraulic hybrid vehicles is given based on hydrostatic transmission technique with secondary regulation. This
paper points out the application conditions and application range of raulic hybrid power technology
Key words: hybrid power technology, secondary regulation, hydrostatic transmission
